Pcb In Air Conditioning
Air conditioner is a weapon that we use to withstand high temperature in hot summer, so that we can have comfortable enjoyment even when the temperature is high. This is the biggest role of air conditioning, followed by providing us with indoor heating function in cold winter. This plays a very important role in the comfort of our lives, this editor will introduce the air-conditioning circuit board, please see the introduction of the air-conditioning circuit board below.Air Conditioning Circuit Board-Introduction to Air Conditioning Circuit BoardThe names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board. The English names are (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board (FPC circuit board is also called flexible circuit board. Flexible circuit board is polyimide Or polyester film is a kind of substrate with high reliability and excellent flexible printed circuit board. It has the characteristics of high wiring density, light weight, thin thickness, good bending!) and soft and hard Combination board (reechas, Soft and hard combination plate)-The birth and development of FPC and PCB have spawned a new product of soft and hard combination board. Therefore, the soft and hard combined board, that is, the flexible circuit board and the rigid circuit board, after pressing and other processes, combined according to the relevant process requirements, to form a circuit board with FPC characteristics and PCB characteristics.Air Conditioning Circuit Board-Air Conditioning Circuit Board Classification IntroductionAccording to the number of layers, circuit boards are divided into three major categories: single panel, double panel, and multilayer circuit board. The first is the single panel. On the most basic PCB, the parts are concentrated on one side, and the wires are concentrated on the other side. Because the wires only appear on one side, this PCB is called a single-sided circuit board. Single panel is usually simple to manufacture and low in cost, but the disadvantage is that it cannot be applied to products that are too complicated. The double-sided board is an extension of the single-sided board. When the single-layer wiring cannot meet the needs of electronic products, the double-sided board is used. Both sides are covered with copper and have traces, and the vias can be used to connect the lines between the two layers to form the required network connection. Multi-layer board refers to a printed board that has more than three conductive graphic layers and the insulating material in between, and the conductive patterns are interconnected as required. Multilayer circuit board is the product of the development of electronic information technology towards high speed, multifunction, large capacity, small volume, thinness and light weight.Air conditioner circuit board-matters needing attention1. Choose a reasonable wire width. The impact interference caused by the transient current on the printed lines of the PCB circuit board is mainly caused by the inductance of the printed wire. Therefore, the inductance of the printed wire should be minimized. 2. Adopting the correct wiring strategy and using equal routing can reduce the inductance of the wires, but the mutual inductance and distributed capacitance between the wires increase. If the layout allows, it is best to use a grid-shaped wiring structure. The specific method is to print the side of the board horizontally. Wiring, vertical wiring on the other side, and then connected with metallized holes at the cross holes. 3. In order to suppress the crosstalk between the PCB circuit board wires, when designing and routing, try to avoid long-distance equal routing, as far as possible from the distance between the line, the signal line and the ground line and the power line as much as possible cross. Setting a grounded printed line between some signal lines that are very sensitive to interference can effectively suppress crosstalk.

Pcb Water Dispenser
A water dispenser is a device that warms or cools barreled pure water (or mineral water) and is convenient for people to drink. Put barreled water on top of the machine and use it with barreled water. It can be divided into three types: warm heat, ice heat, and ice temperature heat. The ice heat machine is divided into two types: semiconductor refrigeration water dispenser and compressor refrigeration water dispenser.Working principle of water dispenser Warm water dispenserWhen the warm water dispenser is used, press the heating switch, and the power supply provides power for the "insulation" indicator to indicate power-on. At the same time, the power supply is divided into two circuits: one circuit constitutes a heating circuit, and the electric heating tube is energized to heat up; the other circuit provides voltage for the "heating" indicator for heating instructions. When the water in the hot tank is heated to the set temperature, the thermostat contacts are disconnected, the heating and heating indication circuit power is cut off, the "heating" indicator goes out, and the electric heating tube stops heating.When the water temperature drops to the set temperature, the thermostat contacts are connected to the power circuit, and the electric heating tube re-heats, so that the water temperature is kept between 85-95°C.There are double protection elements in the circuit of the warm water dispenser. When the water dispenser is over temperature or a short circuit fault occurs, the over temperature fuse automatically melts or manually resets the thermostat to automatically disconnect the heating circuit power supply for protection. The over-temperature fuse is a one-time thermal protection element and cannot be reset. After troubleshooting, replace the new over-temperature fuse with the original model specifications, and then manually press the reset button of the manual reset thermostat. .Hot and cold water dispenserWhen the semiconductor direct-cooling hot and cold water dispenser is used, the direct-cooling hot and cold water dispenser provides normal temperature water from the water tank and enters the water in two ways: one way into the cold tank container, and the cold water is produced through refrigeration; the other way into the hot tank, after heating Out hot water.After pressing the cooling switch, after the AC voltage is stepped down by the power transformer, full-wave rectification by the rectifier diode and capacitor filtering, the DC voltage is output for semiconductor refrigeration component cooling and fan exhaust, and at the same time, the cooling indicator lights. Since the direct-cooling hot and cold water dispensers are not equipped with automatic temperature control, the refrigeration indicator is always on after turning on.Press the heating switch, the heating indicator lights, the electric heating tube generates heat, and the water in the hot tank heats up. When the water temperature rises to the specified temperature, the thermostat contacts are disconnected, the heating power supply is automatically cut off, the heating indicator goes out, and the electric heating tube stops heating. When the water temperature drops to the desired temperature, the thermostat contacts are closed, the heating power is automatically turned on, the heating indicator lights, and the electric heating tube generates heat. Then repeat the above process to keep the water temperature between 85-95°C.Compression refrigeration water dispenserWhen the refrigeration switch of the compression refrigeration water dispenser is pressed, the green indicator light of the refrigeration lights, the compressor starts to operate, the refrigerant vapor that has absorbed heat and vaporization in the evaporator is sucked back, and then compressed into high-temperature and high-pressure gas, and sent to the condensation The condenser dissipates heat into the outside air through the condenser to condense into a high-pressure liquid, and then flows into the evaporator through capillary throttling to reduce the temperature of the water, and then is sucked back by the compressor. In this way, the purpose of cooling is achieved. When the water temperature drops to the set temperature with time, the contact of the refrigeration thermostat is opened, the green indicator light of the refrigeration goes out, the compressor stops, and it enters the heat preservation working condition. After the power is turned off, the water temperature gradually rises. When it reaches the set temperature, the contact of the cooling thermostat closes, the green indicator light turns on when the power is turned on, and the compressor runs. In this way, the water temperature is controlled between 4-12°C.Press the heating switch, the heating circuit is turned on, the red heating indicator lights up, and the electric heating tube heats up. When we specify the temperature, the thermostat automatically resets, cuts off the power, the red heating indicator goes out, and turns into the heat preservation working condition. After the power is turned off, the water temperature gradually decreases. When the temperature drops to the set temperature, the contact of the thermostat closes, the power is turned on, the red heating indicator lights, and the electric heating tube heats up again. In this way, the water temperature is controlled between 85-95°C.The fuse temperature fuse and manual reset thermostat in this type of water dispenser are protection devices. When the circuit is overheated or overloaded, it will automatically fuse or disconnect the circuit, which plays a role in safety protection.Air-cooled refrigeration water dispenserAir cooling is one of the cooling methods, that is, using air as a medium to cool the objects that need to be cooled. Usually it is to increase the surface area of the object that needs to be cooled, or to speed up the rate of air flowing through the object per unit time, or the two methods are shared. The former can be achieved by adding a heat sink on the surface of the object. Usually the heat sink is hung outside the object or fixed on the object to make the heat dissipation more efficient. The latter can use fans (fans) to enhance ventilation and strengthen the cooling effect. In most cases, the addition of heat sinks can greatly improve the cooling efficiency.In any case, the air used must be lower than the temperature of the object and its surface to remove the heat. This is due to the constraint of the second law of thermodynamics, that is, it is impossible to transfer heat from a low-temperature object to a high-temperature object without causing other Variety.

Disinfection Cabinet Pcb
Disinfection cabinet refers to tools for drying, sterilizing, disinfecting, warming and dehumidifying food utensils, tableware, towels, clothing, beauty salons, medical equipment and other items through ultraviolet, far infrared, high temperature, ozone, etc. The appearance is generally a cabinet Box-shaped, most of the cabinet body is made of stainless steel, and the panel is made of tempered glass or stainless steel.Disinfection cabinet principle1. The principle of ultraviolet disinfection cabinetThe sterilization principle of the ultraviolet disinfection cabinet is to irradiate bacteria, viruses and other microorganisms by ultraviolet rays, so as to damage the DNA structure in the body, kill bacteria or lose the ability to reproduce. DNA has the strongest absorption of ultraviolet rays with a wavelength of 253.7nm. The sterilization effect of ultraviolet rays is related to the irradiation intensity and the total irradiation amount, and the kill rate is generally ≥ 99%.2. Principle of high temperature disinfection cabinetHigh temperature sterilization is achieved by heating the temperature to 100 ℃ and maintaining it for more than 15 minutes to achieve the purpose of sterilization. This high temperature sterilization mainly includes microbial organisms including bacteria and viruses. The high-temperature sterilization cabinet generally adopts the far-infrared heating method. The electric heating element heats the air or generates radiant heat. After the appliance is subjected to high temperature for a period of time, the surface of the bacteria, viruses and other microbial organism protein tissues are deformed and thus killed.

The microwave oven, as the name implies, uses the microwave to cook meals. The microwave oven is a modern cooking stove that uses microwaves to heat food. Microwave is an electromagnetic wave. The energy of this electromagnetic wave is not only much larger than the usual radio wave, but also has a "personality". As soon as the microwave touches the metal, it reflects, and the metal has no way to absorb or conduct it; the microwave can pass through glass, ceramic, plastic Insulating materials such as, but will not consume energy; and foods containing water, not only microwaves cannot penetrate, but their energy will be absorbed.The microwave oven is a modern cooking utensil that uses microwave heating. The biggest advantages of cooking food in a microwave oven are fast heating speed, high thermal efficiency, and can maintain the color, aroma, taste and nutritional value of food. Household microwave ovens basically adopt a box structure, which is mainly composed of power transformer microwave generator (magnetron), transmission waveguide, furnace cavity, wave stirrer, furnace door and control part. As shown in the figure below is a popular microwave oven circuit. It is composed of timer, double lock switch, furnace door safety switch, cooking relay and thermal relay.The microwave oven is composed of seven parts: Magnetron: It is the "heart" of a microwave oven. It generates and emits microwaves (DC electrical energy is converted into microwave oscillation output). It is actually a vacuum tube (metal tube). Power Transformer: It is the part that supplies voltage to the magnetron.Furnace cavity: Also called resonant cavity, it is the place where food is cooked, made of metal plate coated with non-magnetic material. Ventilation holes are opened on the left and top of the furnace cavity. The microwave input into the furnace cavity through the waveguide is reflected back and forth in the cavity wall, and each time it passes through and passes through the food. When designing a microwave oven, the side length of the oven cavity is usually a multiple of 1/2 the wavelength of the microwave guided wave, so that when the food is heated, the cavity can maintain resonance and the resonance range is appropriately widened. Waveguide: transmits the microwave power generated by the magnetron to the oven cavity to heat the food.Rotary worktable: The rotary worktable is installed at the bottom of the furnace cavity, at a certain height from the bottom of the furnace, driven by a small motor at 5-6 rpm. Furnace door: The role of the oven door is to facilitate the picking and placing of food and to observe the situation during cooking. The oven door is the front wall that forms the oven cavity. It is a checkpoint for the entire microwave oven to prevent microwave leakage. Time power controller: choose different power to cook or defrost different foods.

Coffee Machine Pcb
People applied electronic technology to the coffee machine, and realized the automatic control of the whole process of brewing coffee such as grinding, pressing, filling, brewing, and removing residues, creating a coffee machine; in the early 20th century AD, he lived in Italy An "impatient engineer" near Poli, who was impatient with dripping coffee for too long, came up with a way to wait for the time to brew coffee with high temperature and high pressure to shorten the time, so he invented Italian coffee Quick conditioning, Espresso also became popular. Semi-automatic coffee machineThe semi-automatic coffee machine, commonly known as the handle machine, is a traditional Italian coffee machine. This machine is based on manual operation of grinding, pressing, filling, brewing, and manually removing residue. This type of machine includes small single-tap household machines, double-tap, three-tap large-scale commercial machines, etc. The newer machines are also equipped with electronic water control, which can accurately and automatically control the amount of coffee brewed.This type of machine is mainly produced in Italy and is very popular in Italy. Its main features are: simple machine structure, reliable work, easy maintenance, and high-quality Italian coffee can be produced according to the correct usage method. The shortcomings of this machine are also advantages: operators must undergo rigorous training to make high-quality coffee with this machine, and excellent baristas can provide customized coffee.Automatic coffee machinePeople apply electronic technology to coffee machines, and realize the automatic control of the whole process of brewing coffee such as preheating, cleaning, grinding, pressing, brewing, and purging powder, creating a fully automatic coffee machine.The high-quality fully automatic coffee machine brews coffee according to the most scientific data and procedures, and all are equipped with a complete protection system, which is convenient to use, and the coffee that can be obtained with just one touch is superior to the convenience. Products of traditional coffee machines.The structure is relatively complex, requiring good maintenance, and high maintenance costs are the shortcomings of this machine. However, the automatic coffee machine is convenient, fast, consistent in quality and high in efficiency. Operators do not need training and other outstanding advantages make it more and more popular with customers.Manufacturers are mainly automatic coffee machines produced in Switzerland, Germany, Italy and other countries, with a wide variety. Among them, the automatic coffee machine made in Switzerland is ingeniously designed and unique. The fully automatic coffee machine made in Italy has a simple appearance, stable and reliable quality, and is well-known in the international coffee machine industry.Automatic coffee machines are divided into large, medium and small sizes according to the number of coffee brewed per hour (generally from 60 to 280 cups per hour). They are suitable for offices and homes. Since Luigi Bezzera launched the first vapor pressure commercial coffee machine in 1901, whether it is Pavoni GaggiaOr other machines that use steam or pistons as pressure are only one boiler: the bottom of the boiler is hot water for brewing coffee, and the steam is provided above, but in order to make steam, the entire boiler must be heated to boiling, making the heat close to the boiling point The water burns the coffee powder, loses the aromatic fat deep in the coffee powder, and even extracts the bitter coffee.Because the water for brewing coffee is heated in a large boiler, the water will not be fresh after being placed in the boiler for a long time, and the temperature difference of the hot water will increase due to the use of steam. The temperature difference of the hot water for making coffee.In order to improve the temperature difference, Ernesto Valente was the first FAEMA in the world to use a pump as a pressure source in 1960In E61, the method of heating the water used to brew coffee is changed so that the water used to brew coffee does not directly contact the heat source, but uses a method similar to water heating.In the middle of the boiler of E61 (hereinafter referred to as the outer boiler) is a tube (hereinafter referred to as the internal pipeline), which uses the pump to introduce fresh cold water into the internal curved pipeline. When the pump pushes fresh cold water through this tube, the cold water will be heated by the hot water in the outer boiler, but it is surrounded by a tube, so the fresh water will not come into contact with the hot water of the outer boiler. The reason why the water pipe is made into a curved shape is to make the cold water have enough time to contact the external boiler and become the hot water temperature just suitable for brewing coffee.Due to the circulation of hot water in the boiler, the temperature of each cup of coffee is very close, whether it is one cup per hour or one hundred cups at once. In this way, not only can the temperature difference be reduced, but also the freshness of the water can be taken into account. The hot water in the outer boiler is only used to generate steam for making milk foam, and it is not used to brew coffee.This is the principle of a single boiler heat exchanger. Until the end of 2018, the internal structure and principle of most Italian coffee machines are still very close to FAEMA E61.From the above description, we can infer: when the capacity of the outer boiler is larger, the temperature difference of the hot water for brewing coffee will be lower, and the effect of the temperature difference caused by the use of steam can be reduced.

Soy Milk Machine Pcb
Soymilk machine, controlled by microcomputer, realizes the automatic preheating, beating, cooking and delayed cooking process. As the emphasis on health is gradually strengthened, in order to be clean and hygienic, many families have chosen to make their own soymilk, thereby driving the market of household microcomputer automatic soymilk machine. Soy milk has extremely high nutritional value and is a very ideal healthy food. Soymilk machine type1. By modeFully automatic soymilk machine: It is the most popular soymilk machine. It is very convenient to use. Just put the soybeans in the soymilk machine and press the switch for about 15 minutes to drink fresh soymilk.Stone Mill Soymilk: Use traditional stone mill soymilk.2. According to the polishing methodSoymilk machine: It is a professional soymilk machine. It is very convenient to use. Both dry and wet beans can be grinded, and there is no need to pour it out for cooking. You can choose this kind of soymilk if you drink it regularly.Juicing and stirring compound soybean milk: the soybeans are crushed by stirring, and only the wet beans can be ground. After grinding, pour it out and cook in a pot. It can be used to squeeze juice.3. Automatic separation refinerIts characteristic is that while grinding the raw materials, the slurry and slag can be separated by itself in the machine body.The machine has reasonable structure, beautiful appearance and convenient operation. It has small size, light weight, low voice, saves personnel, saves electricity, stable performance and reliable quality. I It is easy to clean and easy to move.4. According to functionAccording to whether the soymilk machine can grind five-grain soymilk, dried/wet soymilk, cold drinks of fruits and vegetables, rice paste and corn juice, soymilk machines can almost complete these functions.5. According to usageHousehold soymilk machine: used in general households, the capacity of the soymilk machine can be selected according to the number of people in the family.Commercial Soymilk Maker: Used in places with a relatively large number of people, such as hotels, fast food restaurants and other public places, the cost is more expensive than the household soymilk Maker, the structure is more complicated, and it has good stability.6. With or without meshThere are net-type soymilk machines: the market has existed for a long time, and the material of the net ranges from silk mesh to stainless steel mesh. Features: There are fine grinding of the net, delicate soybean milk, the use time of the motor is longer; it is not easy to clean.Netless soybean milk machine: It came into being with the development of soybean milk machine technology. The stainless steel mesh was removed, and the chassis heating model was added under the new technology. Features: no net, soy milk is rough, the use time of the motor is short; easy to clean.Soymilk machine composition structure 1. CupThe cup is like a huge teacup with handles and spouts, and is mainly used to hold water or soy milk. Some cups are made of plastic and some are made of stainless steel, but they are made of stainless steel or polycarbonate that meets food hygiene standards. When purchasing the machine, it is better to choose the stainless steel cup body, mainly for easy cleaning. The "upper water level" line and the "lower water level" line are marked on the cup body to regulate the amount of water added to the cup body. The upper edge of the cup body just fits the lower cover of the machine head, so as to fix and support the machine head.2. Machine headThe handpiece is the assembly of the soymilk machine. Except for the cup body, the remaining parts are fixed on the handpiece. The head casing is divided into an upper cover and a lower cover. The top cover has a handle, work indicator and power socket. The lower cover is used to install the main components. On the upper part of the lower cover (that is, inside the machine head), a computer board, transformer and beating motor are installed. The lower part protruding from the lower cover has an electric heater, a blade, a net cover, an anti-overflow electrode, a temperature sensor and an anti-dry electrode. It should be noted that the material of the lower cover also needs to comply with food hygiene standards.3. HeaterHeating power 800 W, stainless steel material; there are heating tubes, heating plates, etc. according to the shape of the soybean milk machine, used to heat the soybean milk.4. Temperature sensorIt is used to detect the water temperature in the cup during "preheating". When the water temperature reaches the set temperature of MCU (SH66P20A) (generally requires about 80 ℃), start the motor to start beating.5. Anti-dry electrodeThe electrode is not an independent component, but a stainless steel housing using a temperature sensor. The outer diameter of the shell is 6 mm, the effective length is 89 mm, and the length is much longer than the overflow prevention electrode. It is inserted into the bottom of the cup body. When the water level of the cup is normal, the lower end of the anti-dry electrode should be immersed in water. When the water level in the cup is low or no water, or the machine head is lifted, and the lower end of the anti-dry electrode is removed from the water surface, the MCU (microcontroller) detects this state through the anti-dry electrode to ensure safety. Soymilk machines will be prohibited from working.6. BladeThe shape of the blade is exactly like the propeller of the ship, and it is made of high hardness stainless steel, which is used to crush the beans. There are S type, X type, I type and so on.7. Net coverUsed to hold beans and filter soy milk. In actual work, the mesh cover is fastened to the lower cover of the machine head by fastening the oblique flute. When cleaning, you will find that the mesh cover and the lower cover of the machine head are too tight after being heated. Therefore, when removing the mesh cover, you should first cool it with cold water to avoid scratching your hand or damaging the mesh cover with too much force. In particular, cleaning the net cover is relatively time-consuming and often makes users feel too hard. This problem has attracted the attention of various manufacturers. After technological innovation, Jiuyang Company has achieved a major breakthrough in the improvement of the net cover. The Lafarre net applying Jiuyang's patented diversion technology is matched with the "X-type cyclone blade". After tens of thousands of full-cycle fine refining, it not only greatly It improves the nutritional quality of soy milk and at the same time makes the cleaning of the grille simple and easy.8. Anti-overflow electrodeIt is used to detect the boiling of soybean milk and prevent the overflow of soybean milk. Its outer diameter is 5 mm and its effective length is 15 mm, which is above the cup. In order to ensure the normal operation of the anti-overflow electrode, it must be cleaned in time, and the soybean milk should not be too thin, otherwise, the anti-overflow electrode will lose its protective effect and cause an overflow cup.Soymilk working principle Circuit characteristicsThe fully automated processes such as preheating, beating, and boiling of the general soybean milk machine are controlled by the MCU (Single Chip Microcomputer) related pins, driven by the corresponding transistors, and then implemented by the relay group composed of multiple relays to implement circuit conversion. As long as you master this basic rule, you can conduct circuit checks on all types of soymilk machines to eliminate various types of faults. However, some soymilk models have a little problem with the production of the circuit board. It presses the component number under the component, so only the component can be seen on the circuit board, but the component number cannot be seen. inconvenient.work processAdd an appropriate amount of water, either warm or cold water. After powering on, start the "pulping" function, the electric heating tube begins to heat, and the water temperature reaches the set temperature after 25 minutes. In the pre-beating stage, when the water temperature reaches the set temperature, the motor starts to work for the first pre-beating, and then continues to heat to reach the beating temperature after touching the anti-overflow electrode. In the beating/heating stage, the beating and Heating so that the soybeans are completely crushed, the soybean milk is initially boiled, and boiled. After the soybean milk is boiled, it enters the boiling stage, and the heating tube repeatedly heats the gap, so that the soybean milk is fully cooked and completely emulsified.

Juicer is a machine that can quickly squeeze fruits and vegetables into vegetable juice, small size ones can be used at home. It was invented by Dr. Norman Walker back in 1930. On this basis, the designers later improved the juicers of different styles and different principles.There are two main types of consumer groups for juicer: one is for families with children or the elderly. Children are prone to picky food and the elderly have bad teeth. Juicing their own juice can satisfy their intake of sufficient nutrition; the other is to pursue fashion and life Juicy young people, juicers meet their needs of advocating individual taste. With the improvement of the quality of life, consumers' mentality has begun to transition from the most basic life needs to a nutritious and healthy taste life, which makes it possible for juicers to become more popular. Whether it is a juicer or a food processor, it is in the market introduction period. For most consumers, it is still a luxury product. How to guide consumers' consumption concepts is crucial.Fruits and vegetables are the main foods for humans to take vitamins. Studies have shown that people who regularly eat fruits and vegetables have a higher health status than people who do not like fruits and vegetables. Especially in the prevention of diseases, fruits and vegetables also have an irreplaceable role, which is really a healthy diet. Although fruits and vegetables are rich in nutrients, many people do not like to eat them directly, so many families are equipped with juicers to solve health problems.Three different working principles of juicer1. High-speed centrifugal juicerThis is the most common type of juice extractor on the domestic market. Its working principle is to use a knife net to turn the fruit at a high speed of thousands of revolutions per minute to crush the fruit. The powerful centrifugal force causes the juice to flow into the juice cup, and the fruit residue Throw it into the slag collection barrel. Different brands and models of high-speed centrifugal juicers also have differences in material, power, and feed port size. When selecting, pay attention to choose the one with high power and large feed port.Advantage: The fruit does not need to be cut very small, and the juice is squeezed quickly. It takes only a few seconds to squeeze an apple or carrot, and the juice is clear.Disadvantages: noisy; the juice yield is average. The squeezed pomace is wet and a bit wasteful. It can hardly squeeze juice for leafy vegetables with low water content or particularly soft fruits.2. Low-speed extrusion juicerThis kind of juicer is also loved by many people. Its working principle is to rely on an internal screw rod to rotate at a low speed of 80 revolutions per minute to squeeze and grind the fruit. The juice flows through the filter and the pomace. The slag discharge port is discharged.Advantages: low noise; high rate of squeezing relatively crisp fruit, the squeezed fruit residue is very dry, no waste, and it is also satisfactory for leaf vegetables.Disadvantages: The fruit needs to be cut into very small pieces, and then filled in and squeezed little by little, which takes time; the squeezed juice is thicker, mixed with small pulp fibers.3. Food processorMany people call this machine also called a juicer. Strictly speaking, it should be called a food processor or a blender. It needs to be added with water. Its working principle is that the blade at the bottom of the mixing cup rotates at a high speed, and the food is repeatedly broken under the action of the water flow.Advantages: low price, easy cleaning, and can process a variety of foods.Disadvantages: water is needed to use, cannot squeeze pure fruit juice, can only stir out fruit and vegetable paste.Different juicers use different circuit boards, and we can meet different circuit board needs. The services we can provide are as follows.
