So what is the difference between PAL Granule dryer 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 PAL Granule dryer 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.

PAL Granule dryer granule dryer Equipment principle

Box type plastic resin dryer
PAL dryer
The air circulation system of the hot air circulation oven adopts a fan circulating air supply method, and the air circulation is uniform and efficient. The air source is driven by a circulating air motor (using a non-contact switch) to drive the wind wheel through the heater to send out the hot air, and then to the oven chamber through the air duct, and then suck the used air into the air duct to become the air source for recirculation. Heating use. Ensure the uniformity of indoor temperature. When the temperature value swings due to the opening and closing of the door, the air circulation system quickly restores the operating state until it reaches the temperature value set by the oven.
The hot air circulation oven is divided into five standard models: one-door bicycle oven, two-door two-car oven, two-door four-car oven, three-door six-car oven, four-door eight-car oven; in addition, Qibao drying can be provided according to customer requirements Non-standard customization.
Most of the hot air circulates in the box with high thermal efficiency and energy saving. The oven uses forced ventilation, and an adjustable air distribution board is installed in the oven to dry the materials evenly. The heat source of the oven can be steam, hot water, electricity, far infrared, and a wide range of options. The whole oven has low noise and stable operation. Automatic temperature control, convenient installation and maintenance.
It has a wide range of applications and can dry various materials. It is a universal drying equipment. The arc angle close welding of the inner tank of the oven facilitates the circulation of hot air and is convenient for online cleaning and sterilization.

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. PAL Granule dryer 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.

3. High-quality thermal insulation materials and high-sealing design avoid unnecessary energy loss.
5. Adjustable air inlet.
6. Motor overload protection, phase sequence protection.
Working principle of box dryer:
Put the material to be dried into the movable tray. When the power is turned on, the powerful wind wheel starts to force the air entering from the air inlet to blow to the electric heating tube. The air is heated by the electric heating tube and passes through the holed partition. The wall is evenly blown to the material, and the air carrying moisture will be drawn out of the oven by the top moisture exhaust fan. Such repeated cycles can achieve the effect of dehumidification and drying.

With the widespread use of engineering plastics, PAL Granule dryer pellet Dehumidifying dryers have gradually replaced traditional hot air dryers.
