TPE Dehumidifying dryer Equipment principle
TPE Dehumidifying dryer Since most engineering plastics are hygroscopic, coupled with the influence of weather and regional climate, it is easy to cause the plastic pellets to be excessively wet and fail to achieve the molding effect. In addition, the plastic raw materials are different in the previous granulation process, so the air moisture content and hygroscopicity are also different. Therefore, during molding, bubbles, silver bars, poor transparency, cracks, and poor stability are likely to occur, which seriously affect product quality. The air pipeline of the desiccant dryer adopts a closed circulation system, which can not be affected by the external weather. It can dry the material well in dry weather or wet weather without reversing moisture, and the product quality is high. The dehumidification dryer first draws the air in the environment to remove the moisture in the air under low dew point, and then heats the dried air into one or more standard drying hoppers, which can improve the drying efficiency and shorten the drying time. If a traditional hot air blower uses moisture with external air to dry the material, it is difficult to achieve the drying effect. In addition, when the plastic is taken out of the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere. Traditional hot air blowers cannot prevent the plastic from continuing to absorb moisture, and the drying effect is poor. The use of dehumidification dryers can be divided into stand-alone and centralized. The stand-alone dehumidification dryer usually includes a dryer mainframe, a drying barrel, and a suction machine. The stand-alone dehumidification dryer is suitable for a small amount of various drying, and its advantages are good drying efficiency and convenient and quick material change. The centralized dehumidification dryer includes a dryer host and several drying barrels. Each drying barrel has an independent heating controller, which can dry several different raw materials at the same time, and cooperates with an air volume control valve to control the air volume of each drying barrel. , Suitable for mass production of plastics. 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.
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.

TPE Dehumidifying dryer application
TPE Dehumidifying dryer Dehumidify plastic and plastic products such as PET, PE, PPO, PC, TPE, etc.
Widely used in offices, archives, data, libraries, computer rooms, precision instrument rooms, hospitals and valuables warehouses, chemical fiber, pharmaceuticals, military, glass, food, electronics, metallurgy, printing, warehouses, basements, archives, electricity, Telecommunications, cigarettes, medicine, printing, tea, leather, textiles and other places that require humidity With the widespread use of engineering plastics, Dehumidifying dryers have gradually replaced traditional hot air dryers.
This is a device used to dehumidifying plastic resin to achieve drying. For example,
POM,ABS,TPE,PAL,ABS,CAB,EVA(2),EVOH,LM(4),LCP,PA11,PA6.46.6,PAI,PAR,PBT,
PC,PC/ABS,PC/PBT,PE.HDEPE,LDPE black3%,PE.HDEPE.LDPE black40%,PEEK,PE(1),
PEN,PES,PET,PETG,PI,PMMA,POM,PP,PPO,PPS,PS,[GPPS.EPS.HIPS],PSU,PIT,PUR,
PVC,SAN,SB,TPE,TPE,TPO,TPU,
Dehumidifier dryerand other plastic resins must be dehumidified and dried during the production process to improve the quality of the finished product.
TPE Dehumidifying dryer series are mainly designed for high-efficiency dehumidification of engineering plastics with strong hygroscopicity. Using the honeycomb runner with ceramic fiber as the base material, which represents the highest technological achievements of today, as the core component, the dry air provided can easily reach -40℃ dew point, and ideally it can reach -50℃ or even lower dew point , And the dew point temperature is stable, ensuring the high quality and stability of the molded plastic products. The whole series adopts P.LD. temperature control system as standard equipment; also provides PLC control with LCD touch-sensitive human-machine interface and can monitor the dehumidification effect of the machine Dew point meter is optional, the maximum drying air volume of this product can reach 3000m3/hr. The plastic before molding must be dried to an orientation ratio of less than 0.02%, which is completely bad, sprue adhesion, burrs, bubbles, silver bars, flow marks, cracks, dimensional stability and internal stress. Product defects (for example, insufficient physical properties and strength) are caused by sufficient dehumidification of the plastic before molding. Especially for PET, PBT, PA, PC and other high water absorption plastics, drying equipment with an ultra-low dew point of -40°C is required.
TPE Dehumidifying dryer can be dried to a volume ratio of less than 0.02%, which solves the shortcomings of short circuit, gate adhesion, bubbles, silver bars, cracks, poor dimensional stability, internal stress and insufficient physical strength of the product. There are a lot more.
Mainly used in plastic products, automobiles, optical discs, experiments, communications, optics, etc.; the rotary honeycomb can reach a low dew point of zero bai for dehumidification and drying at -40°C. In the case of enhanced configuration, the dehumidification dew point can be as high as -50°C. It is a choice for high-precision industries.
