What Do The fFour-piece Quilt Comforter Sets Refer To?

The four-piece quilt comforter sets refers to the essentials for bed use when sleeping. It mainly includes two pillow cases, a quilt cover and a bed sheet. Most of the materials are pure cotton, and there are silk cotton and fiber. The four-piece set on the bed occupies an important position in home life. According to the differences of the four seasons, there are many differences in the types of fabrics of the four-piece set. The fabric structure of four-piece sheets is generally divided into plain weave, twill weave, satin weave, and jacquard. Low-grade plain weave products have many intertwined points, firm texture, flat surface, the same appearance effect on the front and back, and good abrasion resistance and breathability. Twill fabric is a more common mid-range product, with longer floating lines and a soft feel. Tissue fabrics are denser and the product is thicker. Satin fabrics are mostly used in middle-to-high-grade bedding, with soft texture, smooth and shiny fabric. What fabrics do the four-piece sheets have? • Cotton fabric Pure cotton fabric is considered as a comfortable fabric, and it is the most common four-piece fabric in the family. Advantages: Absorbs water, sweat and sticks to the skin, and does not have any irritating properties to human skin. Cotton fabrics dominate the bedding. In the cold winter, cotton fabrics have better warmth, giving a soft and comfortable feel as a whole, and the price of cotton bedding is also moderate. Disadvantages: The biggest disadvantage of cotton fabrics is that they will shrink after frequent cleaning. • Linen fabric Advantages: Linen sheets make it easier to fall asleep than cotton sheets, and they sleep soundly and deeply. Examination of the skin showed that the type of linen bedding had no irritation to the skin, reduced skin temperature and muscle tension, and the linen fabric also had the effect of inhibiting bacterial growth. Disadvantages: The bedding of linen fabric feels rough, and it is generally used as a bed cover during the day, or as a nursing bed sheet on a mattress. • Polyester fabric Polyester fabric is a blended fiber, which is a blend of some natural fibers and chemical fibers. Both the comfort of natural fibers and the durability of chemical fibers. Advantages: Low cost, good color fastness, bright colors, good shape retention, and more durable. Disadvantages: Easy to pilling, easy to electrostatic, poor affinity. • Brushed Fabric The brushed fabric is a high-grade combed cotton. During the post-processing, the fabric is brushed to make the surface of the fabric have a certain velvet feel and improve the fabric feel. Advantages: Sanding is also called sanding, which can make warp and weft yarns produce hairs at the same time, and the hairs are short and dense, the suede is flat, the hand feels full and soft, rich in suede, and the luster is soft without aurora. Disadvantages: Because the brushed cotton products are made of cotton fibers and lack elasticity, cotton clothing will be easily deformed, and it is easy to stick to wool and difficult to remove completely. Not only that, the brushed fabric is also particularly afraid of acid. When the concentrated sulfuric acid contaminates the cotton, the cotton will be burned into holes. • Bamboo Fiber Fabric Bamboo fiber fabric belongs to a new type of fabric. It is made from natural moso bamboo as raw material and digested by hydrolysis. Advantages: Because the cross section of the bamboo fiber is covered with oval gaps, it has good air permeability, and it is cool and comfortable for people to sleep on it. Bamboo fiber is a natural fiber that can produce negative ions and far infrared rays, which can promote blood circulation and metabolism. Disadvantages: During the weaving process, due to the characteristics of easy absorption of bamboo fiber, large wet elongation and large plastic deformation, it is very easy to be brittle. 100% bamboo fiber in manufacturing has not solved the shrinkage problem well. • Silk Fabric Advantages: The most high-end fabric is silk fabric. Silk fabric has gorgeous appearance, richness, natural soft light and glittering effect, feels comfortable, high strength, better elasticity and moisture absorption than cotton, etc. Disadvantages: Easy to soil, and less heat resistant to strong sunlight than cotton. Still have to learn to maintain a variety of bedding in order to make them last longer.

The role and advantages,disadvantages of plate heat exchangers

Plate heat exchangers are a type of mobile device that transfers heat between metal plates because the liquid is spread over more surfaces, which increases the exchange rate. Metal tubes are used to heat fluids. The role of plate heat exchangers The plate heat exchanger is based on different external and internal components, the welding plate exchange plates are welded together, and the brazed plate type construction model is vacuum brazed. In many cases, in order to make smaller sections work better, some chambers are designed to be thinner, allowing most of the liquid to contact the plate, improving heat transfer. The plate heat exchanger can play a good heat transfer effect in the boiler heating in winter. In the daily use process, it is necessary to do a good job of protecting this equipment. The plate heat exchanger is a kind of equipment that can play multiple benefits and functions for us. The user clearly knows its role and protects it so that it can play a greater role. Advantages of plate heat exchangers High heat transfer coefficient. The plate heat exchanger has a small flow channel, the plates are wavy, and the cross-section changes are complex, which makes the flow direction and velocity of the fluid constantly change, which increases the disturbance of the fluid and has a high heat transfer coefficient. Great adaptability. The required heat transfer area can be achieved by increasing or decreasing the plate. A heat exchanger can be divided into several units, which can be used for heating or cooling between several fluids at the same time. Compact structure, small size and few consumables. The heat transfer area per cubic meter volume can reach 250m2, and the heat transfer surface per square meter only needs about 15kg of metal. Dirt factor is small. Due to the large flow disturbance, dirt is not easily deposited. The plate heat exchanger plate is of good material and has little corrosion, which makes its fouling coefficient value smaller. Plate heat exchangers mainly use metal plates, so the price of raw materials is cheaper than the same metal pipes. Disadvantages of plate heat exchangers 1) Poor sealing and easy to leak. The gasket needs to be replaced frequently, which is troublesome. 2) The use pressure is limited, and generally does not exceed 1MPa. 3) The use temperature is limited by the temperature resistance of the gasket material.

The Type of HQ Wireline Overshots

PEERCHEER offers compact BQ Ezy lock overshots for use with hq wireline overshots. Working Principle When the salvager enters the center tube of the drill bit, the slider moves up, so that the salvager head can be inserted into the center tube. When the slider is up, the slider moves down and tightens, and the friction bit is used to lift the drill bit. The connecting rope on the slide will tighten tightly, just pull out the center tube. Before salvaging, you must first determine the position of the drill bit at the bottom of the hole. A thin plate can be bolted to the bottom of the drill rod. The drill rod can be dropped to the bottom of the hole and pressed onto the drill bit. The indentation left to determine the relative position of the hole bottom drill bit and the center of the drill turret, and then move the rig or turntable so that the center of the turntable is facing the center tube of the wound head, then it can ensure that the fishing device can be accurately inserted into the center tube. Key points of operation: (1) Measure the length of the salvage tubing, verify the depth of the fish roof well, and the salvage entry (2) Select the fishing tool and go down the fishing pole to explore the fish top (3) Salvage in combination with the salvage tools used (4) Trial mention, if the reading of the dynamometer increases obviously, indicating that it has been held, then lift the pipe string steadily and remove the falling objects. (5) If a card is encountered after fishing, the card will be unlocked or reversed, the salvage pipe will be pulled out, and the next step will be studied.

Notes on choosing the right protective plastic film

As a manufacturer of

protective films

, Auge is committed to researching the types of protective films and the driving force of market growth. As the demand for the protective film market continues to grow, considering the increasing demand for product protection, it is very important to choose the type that suits your needs.

Determine the type of surface to be protected. The protective film can be applied to many types of surfaces, such as:

Metal

Plastic

Glass

Painted Surface

In addition, these types of surfaces can have a variety of textures, including smooth, embossed or coated. Therefore, it is necessary to understand the nature of the surface to be protected. If an unsuitable film is selected for a given surface, it may cause bonding failure.

Understand Application Conditions of Protective Plastic Film

It is a good idea to understand the conditions of the protective film in a given application. Clearly pre-determining the nature of the application will help ensure that the selected protective film can maintain the performance level throughout its required life cycle and reduce the possibility of failure.

Know the Attributes of Protective Plastic Film

Although all protective films are designed to protect surfaces, they have unique properties. These include:

Color tint

Optical grade clarity

The ability to prevent electrostatic discharge

Before choosing a protective film, you must first evaluate the required characteristics. This will ensure that the film provides the correct quality to achieve the desired end-use results.

Smart Adhesive for Protective Plastic Film

Adhesives also play an important role in determining the performance of protective films. Therefore, it is best to ensure that the selected adhesive meets the needs of the end use before manufacturing the film.

Why You Need An Automated Optical Pcb Inspection Of The Assembly

Whether turning the pages of the Sherlock Holmes mystery or watching the replay of "Monk", I hope to see these investigators find important details that others cannot. However, even the largest of these detectives finds it difficult to find problems on the assembled printed circuit board. On complex circuit boards, there may be thousands of opportunities for defects, and manual inspection simply cannot reliably search for all defects within a reasonable time. As part of the different inspection methods that contract manufacturers should use, the Automated Optical PCB Inspection (AOI) system will handle most inspections on the PCBA. The system can quickly assess thousands of details, which are too small for the human eye to capture and report any detected problems to the operator.

What is AOI PCB assembly inspection and how does it work?

Automated optical inspection equipment has been around for a while, and it is constantly being improved and updated to improve its functionality. This inspection equipment is used in many industries, including PCB manufacturing, for inspecting bare boards, solder paste applications and assembly. For PCB assembly, the AOI system will check component placement and soldering, and will alert inspection technicians of various potential problems, from the use of incorrect parts to bad solder connections.

AOI PCB inspection equipment

relies on high-resolution camera systems and different illumination sources such as fluorescence, LED, ultraviolet and infrared to capture image arrays. When assembling a new PCB, the contract manufacturer will run the circuit board through the AOI system after the parts are placed, and then run again after the circuit board is soldered.

In subsequent runs, the AOI system will scan each assembled board and compare these images with the archived images of the gold standard board. When areas that fail to meet the gold standard are found, it will mark these areas as possible defects so that technicians can conduct more detailed inspections.

AOI adjustability: the key to successfully preventing assembly defects

PCB AOI equipment can be "adjusted" according to the needs of the assembled board. The system's adjustability allows contract manufacturers to filter out acceptable problems and capture hard-to-see defects that were difficult to find through visual inspection in the past. The manual inspection process requires technicians to look at every part, marking, and solder joint on the board, which may involve thousands of details in order to check on a complex board. With so many details to check, it is easy to understand the incompleteness.

On the other hand, the

automated optical pcb inspection

system enables highly skilled inspectors to focus only on the relatively few potential defects identified by the system. Compared with the labor-intensive manual inspection process, this allows your CM to discover actual defects in a relatively short time.

At

Insun

, we have a variety of testing and inspection methods that we often use on all production boards including AOI. From the incoming inspection of raw materials and parts to the functional testing of the assembled boards under power, we all ensure that your boards have been assembled and operated as expected. Our goal is to provide you with the best assembled printed circuit board.

Maintenance Method of Constant Temperature and Humidity Electronic Test Chamber

Maintenance method of constant temperature and humidity electronic test chamber: 1.Before the test, be sure to check that the water level in the water tank is not too high or too low. If the water overflows the water tank or is too low, the wet ball test cloth will not absorb water properly, and the accuracy of the wet ball will be affected. The water level can be kept about six minutes full. The water level of the water tank can be adjusted to adjust the height of the water tank. You need to check and add water almost every two or three tests. You can see the water pipe in front to replenish the water. The machine will alarm and stop working when there is no water. 2.If the machine is operated below 0 ℃, avoid opening the door of the box as much as possible, because at low temperature, if the door is opened, frosting of the internal evaporator and other parts is likely to occur, especially the lower the temperature, the worse Must be opened, the door opening time should be minimized. 3.When the temperature test box has completed low-temperature operation, be sure to set the temperature to 60 ° C and perform the drying process for about half an hour, so as not to affect the measurement time or freezing phenomenon of the next working condition. 4.The radiator (condenser) of the freezer should be regularly maintained and kept clean. 5.The humidifier barrel's water inlet pipe must completely exhaust the remaining air to prevent water from entering. After the machine finishes running at low temperature, it is necessary to set the normal temperature condition (30 ± 5 ℃) so that the temperature in the box will be normal temperature when the machine is stopped, so as not to affect the freezing phenomenon caused by the low temperature in the box and the fogging of the window glass . 6.During operation, unless absolutely necessary, please do not open the door of the box, otherwise it may cause the following adverse consequences: －High temperature and humidity rushing out of the box is very dangerous for the operator. －The inside of the door is still hot, which is easy to cause injury. - Hot air may trigger a fire alarm and cause incorrect action. 7.Please note that the automobile rain testing chamber must be grounded safely and securely to avoid static induction. 8.Avoid turning off and on the freezing unit within three minutes. 9.If a hot sample is placed in the box, please use an external power supply for the sample power control. Do not use the power supply of the machine directly. 10.Circuit breakers and temperature over-temperature protectors provide safety protection for the test products of this machine and the operator, so please check regularly. 11.The correct installation of wet ball gauze can only ensure the correct measurement of relative humidity. 12.Testing of explosive, flammable and highly corrosive substances is absolutely forbidden. 13.Please read the controller manual and related manuals before operating the constant temperature and humidity machine.

The market explosion of TWS has boosted the market demand for rechargeable button batteries exponentially

What is the TWS Coin Battery? The TWS headset is a true wireless Bluetooth headset. The main feature is that it has no physical wires and is easy to carry. The cordlessness has prompted TWS headsets to require rechargeable batteries, including a pair of headset batteries and a charging compartment battery, accounting for about 10% -20% of the total cost. It is a key component that affects various performances such as battery life. After replacing therechargeable coin battery, the overall length of the headset becomes smaller, and the wearing aesthetics are significantly improved. We expect button batteries to become the mainstream of the industry in the future. At present, VDL is one of the major manufacturers of TWS earphone button batteries in the world, with independent core patent technology. At the same time, considering the precision of the TWS cell manufacturing process and high technical barriers, new entrants will face patent disputes, insufficient production capacity, technical barriers and other issues. VDL is expected to usher in high growth early next year. VDLdesigns, manufactures and sells small polymer lithium batteries and is recognized as one of China's top high-tech companies.                                                1254C Coin Battery Compared with other batteries, button batteries are easier to standardize, more ergonomic, high space utilization, and easy to process and assemble. VDL's button battery has the following advantages: 1. Independently developed patented technology 2. High performance 3. Good security 4. Small size, durable and safe for TWS The Advantages of Rechargeable Button Batteries When a button battery such as Airpod Pro is rated at 93 milliwatts, we believe that it has reached its maximum capacity. However, with the development of new Bluetooth technology, TWS can certainly use longer-lasting batteries. To keep prices low, button batteries will not be used in semi-wireless earbuds because lithium polymer batteries are cheaper and fit the dimensions of these earbuds. Before reducing the receiving coil to a diameter equal to or less than 12mm, it can be installed in a coin cell. Moreover, the button battery has been wirelessly charged during the day, and it is not far away that the charging box becomes a wireless charger.

CNC Glass Cutting Machine

The use of plexiglass began in the 1930s and is a synthetic polymer plastic whose main characteristic is optical transparency. The new material plexiglass completely solves the requirements of aircraft development, providing structural simplicity and the required rigidity and safety. At present, the main characteristics of plexiglass are required in various industries, such as high strength, impact resistance, low weight, high transparency, and easy processing. For small businesses specializing in advertising, design services, architecture, and souvenir products, plexiglass is almost the main structural material. Processing methods Plexiglass is perfectly processed by cutting. However, this will produce a large number of small chips. Since the plexiglass melts at a relatively low temperature, the generated chips are easy to sinter and stick to the cutting edge of the tool. This makes it difficult to process and reduces the quality of the finished product. In addition, plexiglass is very sensitive to the sharpness of the tool: the minimum wear of the tool or milling cutter will cause a sharp decline in processing performance. Another disadvantage of mechanical processing is that plexiglass is prone to contact damage. In addition, this is not only applicable to cutting tools-when the workpiece is fixed on the table, it may damage the surface of the workpiece. However, it is almost impossible to restore the product, such as finishing the polishing, so that the transparent surface is free of white turbidity! CNC glass cutting machine can provide very high cutting accuracy and seam fineness. Because there is no cutting force, there is no need to install the workpiece, which means that the surface will not be damaged by mechanical clamping. Laser cutting and engraving will not produce chips or dust. The dot effect produced by the high-energy laser on the surface of the plexiglass will only cause the material to evaporate-the generated gas can be easily removed by the machine's standard exhaust system, and will not pollute the environment. The laser processing of plexiglass is carried out at high speed, and the specific processing cost is the lowest. The CNC glass cutting machine can do all the work with plexiglass: coating large-format workpieces, graphically cutting complex contours, performing surface engraving and even 3D processing! When choosing laser products for "plexiglass", we need to pay attention to: 1) Laser tube type Generally, most "budget" models are equipped with laser tubes with mixed gas active media. The characteristics of gas lasers are high radiation stability and low specific energy consumption. 2) The shape and size of the processed workpiece It is always recommended to take the machine "in large quantities" to the desktop area. The limiting factor here may be the budget and the area where the machine will be located on the production floor. It should be noted that machines with large working areas are more versatile equipment. 3) The power of the laser tube determines the thickness of the workpiece For engraving plexiglass, 25-60 watts of power is sufficient. Cutting end-to-end workpieces with a maximum thickness of 10 mm will require 60-80 W of power. To process thicker workpieces, as well as parallel processing of workpieces, lamps with a capacity greater than 80 watts are required. 4) Processing speed The higher the product's productivity, the greater the company's profit. Therefore, when choosing a laser machine, the focus should be on the maximum speed indicator. 5) Warranty support and service These factors are very important, and equipment suppliers should be selected first, not only through the verification of the machine model sold, but also through high-quality customer service throughout the life of the equipment.

cause of bicycle helmet failure

When I was riding by the river, I found another cyclist fell and caused head injuries. This is due to improper wearing of the helmet. I hope this is an isolated incident. But this exact situation has happened several times before. Although this helmet failure is not as common as several others, I have seen them many times, which is very painful. Improper installation or incorrect wearing of the helmet will affect the safety of the helmet, and may not provide all its safety functions when it is dropped or crashed.

The most common cause of bicycle helmet failure

Carry helmetWearing

attractive bicycle helmets

in this way is usually because the helmet is too large or the belt is not adjusted properly, which reduces safety and increases the chance of the helmet loosening in a crash.Helmet leans backTilt the helmet backwards may be useful for Hollywood cowboys, but not so effective for city bikers. First, it looks stupid. But what's worse is that if you fall, your entire forehead and face are vulnerable.Reverse the helmet

How to find the right helmet and wear it correctly

Choose the correct sizeStart by measuring your head circumference and confirm that your head circumference fits the size range of the helmet. These dimensions are almost always in centimeters, so using a metric tape measure will solve the problem. Make sure that the helmet you choose is just the right size, not too small or too big.Dial in to FitThe

popular bike helmets

have a dial adaptation system that can be customized. This dial can expand and retract the helmet to half of the maximum size in either direction to accommodate a wider range of head shapes and sizes.Adjust the beltAfter setting the helmet, arrange the belt and position it so that the front is about two fingers wide from the top of the eyebrows. Adjust the position of the side straps so that the straps form a "V" shape under and in front of your ears, and the front and back straps will not be slack. Tighten the chin strap until you can install two fingers underneath.

Why are digital labels better for your products?

Digital printing is quickly becoming a popular choice for printing product labels and stickers. There are many good reasons for this, including cost reduction, high quality, fast turnaround and small batch production capacity. What is digital printing? Digital label printing(label printing machine) obtains the digital file of your design, and then prints the image directly on the selected label material on the printing press. Unlike flexographic printing, all colors and images are produced in one step. These printing presses run slower than flexographic printing presses and are therefore ideal for ordering in small batches. Common features of digital label projects Decoration or original label printing If you want the label to help sell the product and represent the brand, print quality is the key. Color consistency, image registration and color vividness can all be solved by digital labels. For example, beverage labels, food bag labels, and private label brands often run in our digital meeting rooms. If your label will be used for branding, it is most likely suitable for digital advertising. A Short-term order Compared with flexographic printing, the minimum value allowed by digital printing is much lower. If each product requires 500-25,000 color labels, then digital labels are likely to fit your product. For short-term operation, you will not need to keep unwanted inventory. Variable printing on the press Variable data printing is a form of digital printing, including on-demand printing, where elements such as text, graphics, and images can be changed from one printing to another without stopping or slowing the printing process. When printing labels on a flexographic label printer, a new label die may be required to obtain a unique shape or size. These may cost hundreds of dollars. Flexo printing machines also use metal plates to create images for each color of the design, just like regular printing machines. Packaging sustainability Flexo label printing can waste a lot of material, because during the setup process, the press operator must enter the color and align the plate to make the label perfect. However, using digital label printing, basically does not need to be set to reduce your costs. Flexibility One of the best features of digital label printing is the flexibility of artwork. As the product line evolves, you may need to update the label. Because the digital version does not require a printing plate, you can easily modify the design and send the revised artwork, and you can print without paying an additional printing plate fee. This is very useful for start-up brands or series running with multiple SKUs. Not every product is suitable for digital printing. Most medical device labels, two-color labels, or complex coupon labels do not work well with digital printing. If you use a small amount of labels in any type of food packaging for beverage manufacturing, digital label printing may be a way to save you time and money.

Through the research and development of stone paper production technology and the exploration of performance characteristics, the application of stone paper materials in the packaging field is promoted. The core layer of the stone paper honeycomb paperboard is formed by a chain compression molding process, that is, the core layer is pressed by the core paperboard through a chain molding device with a protruding honeycomb hexagonal prism structure, and then the prepared core layer and the stone paper are pressed. Tissue paper is melt-bonded at an instant high temperature. Compared with the traditional corrugated cardboard of the same specification, the stone paper composite corrugated cardboard with a thickness of 4.50mm has a break resistance of at least 2.5 times and a puncture strength of 1.7 times. The core layer of the stone paper corrugated cardboard adopts the extrusion flow calendering molding process, that is, the stone paper is directly extruded and cooled in a molten state through a corrugated die to obtain a core layer. Each bonding surface is pre-heated and bonded by instantaneous high-temperature hot-melt bonding. Compared with the conventional honeycomb paperboard of the same specification, the prepared honeycomb paperboard with a basis weight of 202g / m2 has a flattening strength of 2.6 times that of the traditional honeycomb paperboard, and the burst resistance is at least 2.5 times that. Lightweight stone paper, which is a light weight multi-layer stone paper composed of foamed stone paper and non-foamed stone paper. Foaming and hot-melt compounding are the key technologies.

How smart health watches can help you improve your health

In recent years, smart watches have attracted considerable attention. "What are smart watches actually doing?" This is a question worth considering. From the most basic point of view, smart watches are an extension of smartphones. They can receive notifications, receive calls from your wrist, allow you to use the application and tell the time. This always-on function is of great significance for changing the lifestyle of watch owners and even their health status. Here are a few ways smart watches can help you improve your health: Step tracker. One of the easiest ways to improve health and improve exercise is to take 10,000 steps a day. The smart watch has a built-in pedometer, which makes it easy to check the number of steps performed. Sleep monitoring. According to statistics, more than one-third of adults sleep less than 7 hours a night, and continued lack of sleep can have long-term negative effects on the body. Smart watches can track sleep patterns when worn at night. They can let you know how many hours of sleep you have and the number of uninterrupted hours. Although these sleep statistics cannot replace professional sleep research, they can help you identify patterns and set goals to improve sleep quality and quantity. Exercise reminder. Everyone knows that we should exercise, but usually the hardest part of exercise is to get used to it. Setting exercise reminders is a great way to turn good goals into good habits. If you don’t have a mobile phone, it’s easy to miss reminders, but your smart watch will vibrate on your wrist, letting you know it’s time to go to the gym. Timer and stopwatch. Although this is not necessarily a new feature of smart watches, it has been used on digital watches for many years. Timers and stopwatches are very useful for runners, swimmers and cyclists. It is easier to listen to music while exercising. You may have your favorite music on your smartphone, but it is often awkward to exercise with a large phone. Many smart watches allow you to load a limited number of favorite songs directly onto the watch independently of your smartphone. Combined with Bluetooth headset, it can bring greater convenience and comfort when exercising. Custom dial. One of the most popular features of smart watches is the ability to customize the dial, allowing you to express your personality. In addition to the interesting, colorful dial, many smart watches also allow you to add health tracking on the main dial. Add the steps you have taken or increase the target on the dial to put your health first. The data is analyzed simultaneously. Despite the limited processing power of smart health watch themselves, they are always connected to a smartphone, which allows you to synchronize the health conditions (sleep, steps, etc.) you collect with your phone. Even with the most powerful features in the world, smart watches still rely on one very important thing: you want to make the most of it.

The origin of organic oyster sauce

Oysters are a kind of marine mollusk, with delicious meat and rich nutrition. In 1888, in the South Water Village of Zhuhai, Guangdong Province, Li Jinshang, the inventor of oyster sauce, cooked oysters on a fire as usual. When he was busy with other things, he forgot to take care of him. I'm afraid it's boiled! When he lifted the lid of the pot, he saw in front of him a thick layer of thick juice with a tan color and a fragrant fragrance, which attracted appetite. Unintentionally, a new condiment-oyster sauce was invented in this way! Many people think that organic oyster sauce is a kind of fat. In fact, oyster sauce is not a fat like soy sauce, but a seasoning. The soup made from boiled oyster sauce is oyster sauce after filtering and concentration. It is a rich and delicious seasoning. A high-quality oyster sauce should have the umami flavor of oysters, and a vegetarian oyster sauce made from mushrooms. Oyster sauce is widely used, suitable for cooking a variety of food ingredients, such as meat, vegetables, soy products, fungi, etc., can also be mixed with a variety of pasta, shabu seafood, edible food, etc. Oyster sauce is also suitable for a variety of cooking methods. It can be used directly as a dipping point for seasonings. It can also be used for heating, braising, grilling, roasting, frying, and so on. It can also be used for cold filling and snack meat fillings. Tips for using oyster sauce Mixed seasoning Not only can oyster sauce be seasoned alone, but it can also be used in conjunction with other seasonings. Seasoning with oyster sauce should never be shared with spicy seasonings, vinegar and sugar, as these seasonings will mask the umami flavor and detract from the special flavor of oyster sauce. Should not be cooked too long Oyster sauce will lose its umami if it is cooked in a pot for a long time. Generally, it is advisable to add oyster sauce immediately before or immediately after cooking. Mix the broth and thicken When using oyster sauce to make the gravy, it is not possible to directly add the oyster sauce. Instead, it should be mixed with the broth and diluted to make the oyster sauce. The oyster sauce is the best when the dish is eight when it is mature. It is easier to develop color and the oyster flavor is fragrant. Marinated ingredients Garlic oyster sauce is also a good seasoning for marinated ingredients, allowing the unique umami flavor of oyster sauce to penetrate the interior of the raw materials, increasing the taste and texture of the dishes. When cooking meat offal, marinating in oyster sauce can remove the offal smell of the offal and make the sauce rich and fresh. Use proper oyster sauce to marinate the meat, which can remove the meaty smell, supplement the lack of the original taste of the meat, and add the strong flavor of the dishes to make the taste more delicious. Avoid high temperature cooking Generally used as seasoning materials, it has special freshness, but avoid cooking at high temperature, otherwise it will lose the unique fresh taste, and the nutrition will be scattered.
