Energy-saving dehumidification dryer,Dehumidifying dryer,Plastic desiccant dryer,Plastic dehumidifier.Plastic dryer.Resin dryer.Resin dehumidifier So what is the difference between PET plastic energy saving dehumidifying dryer and ordinary dryer? Under what circumstances is the plastic desiccant dryer produced? To understand this problem, we must first talk about ordinary dryers. Ordinary dryers use electric heating to heat hot air to dry materials inside the space at a high temperature, so as to evaporate water from the materials. The incoming air heated by the electric heating is the air in the environment. This is what we usually call a hot air dryer. Therefore, under current weather conditions, incomplete drying of materials will occur. Because electric heating must first heat the incoming air, but the incoming air contains high moisture, how can the material be dried thoroughly? (Mainly reflected in materials with high moisture absorption rate, similar to nylon). In view of the above situation, firstly, the ambient air is drawn in to remove the moisture in the air at a low dew point, and then relatively dry air is used to heat the material into the dryer to dry the material. Therefore, the difference between these two dryers is that the moisture content of the inlet air used for drying is different. One has processed the inlet air moisture, and the other has not processed the inlet air moisture. The parameters of the PET plastic energy saving pellet dryer are different depending on the product, particle size or powder, and the drying and dehumidifying time parameters of the predetermined material are also different. For general, you can check the following comparison table.

can dry to a moisture content below 0.02%, and solves the shortcomings of poor transparency, sprue sticking, bubbles, silver bars, cracks, poor dimensional stability, internal stress, and insufficient product physical strength. PET plastic energy saving pellet Dehumidification and drying feeding equipment series are composed of: non-heat dehumidification dryer, heat preservation type drying barrel and all stainless steel suction machine. The suction machine can transport the raw materials from the drying barrel to the forming machine, and can also transport the raw materials from the storage barrel to the drying barrel. According to customer needs, a kind of raw material can be delivered to two molding machines, vacuum motors and safety filter dust collectors are installed inside the machine. According to the production needs of different products, we can provide a powder-removing suction machine to separate the powder in the raw material and capture it. This device has a compact structure and is suitable for the production of precision injection products using engineering plastics such as connectors, precision gears, mobile phone communications, digital cameras and product size requirements, so that the moisture content of the raw materials after wet and dry is low and stable, which can meet strict requirements Technical and quality requirements.
Most engineering plastics are hygroscopic. When the plastic is taken out from the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere.
If it is a conventional hot-air barrel dryer, it is Humid external air can dry the plastic, so it cannot prevent the plastic from continuing to absorb moisture.
1. The internal circulation of the dehumidifier: through the operation of the compressor → discharge high-temperature and high-pressure gas through the exhaust port → enter the condenser for cooling → become a low-temperature and high-pressure gas → pass through the capillary tube → become a low-temperature and low-pressure liquid → evaporate and suck through the evaporator Heat → until the compressor becomes a low-temperature and low-pressure gas. So it goes back and forth.
2. The external circulation of the dehumidifier: under normal startup → through the operation of the fan → moist air is sucked in from the air inlet → passes through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → Pass through the condenser to dissipate heat → blow out from the air outlet.

PET plastic energy saving pellet dryer Precautions

1. Dehumidifing-dryer The desiccant dryer should be cleaned frequently and kept clean. The dehumidifier should be placed in the center of the room. The air inlet and outlet of the refrigerated dryer should not be blocked by obstructions, and the air filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the evaporator surface will freeze and the dehumidifier effect will be weakened. If the ambient temperature exceeds 40℃, the pressure in the system will increase and the compressor will overload. At this time, the overload protector The circuit should be cut off, otherwise the compressor motor will be damaged. So the best temperature range for dehumidifier is 15℃~40℃. If the humidity in the air is below 30%, it will be too dry and uncomfortable, so a reliable humidity controller will control it to maintain the range of 50% to 60%. When in use, close doors and windows as much as possible to achieve dehumidification in the room. The body of the desiccant dryer must be placed flat, not tilted or turned sideways, to avoid machine failure or abnormal noise.
2. Dehumidifing-dryer The water storage in the desiccant dryer is too full. In order to avoid overflowing and contaminating the ground, when the machine body must be moved during operation, please unplug the power cord first, and then pour out the water in the water storage bucket. After moving the dehumidifier, it is best to put it statically for four to six hours before starting to use it. Because the compressor pipeline in the dehumidifier contains cold coal, it must take four to six hours to return the cold coal to its original position after being moved.
3. Clean the air filter regularly (about once every two weeks) to maintain the dehumidification and dust removal efficiency and life of the machine. Clean the air filter and wash it with water below 40°C; it is better to clean it with detergent. After washing off the dust, rinse it with water, dry it in the shade and put it back into the body. When cleaning the body, wipe it gently with a damp cloth; avoid directly splashing water for cleaning, so as not to damage the electrical insulation. Adhesives on the surface of the body can be cleaned with soap and water. Avoid spraying with gasoline, petroleum spirit, solvent or spray insecticide to avoid peeling paint or discoloration. Do not use thin rods or iron wires to dig out the inside of the machine to avoid malfunction or danger. Please unplug the power cord to maintain the life of the machine when it is out of power, not used for a long time, or when traveling.
(1) Ensure that the hot air is clean.
(2) Measures should be taken to prevent coke dust and avoid backflow of hot air.
(3) During the drying process of the material, all parts of the equipment in contact with the material must be cleaned and disinfected.
(4) For viscous materials, measures should be taken to minimize sticking.
(5) In order to improve the solubility, instant solubility, and dry products, they should be continuously discharged from the drying chamber quickly and packaged after cooling.
(6) The exhaust air temperature is allowed to exceed the requirements to ensure product quality and safety.
