Plastic dehumidifying drying unit Difference and application
In the past, the traditional hot-air dryer used by plastic production enterprises, if it encounters humid weather, it is difficult for the hot-air dryer to accomplish the drying purpose.
Plastic dehumidifying drying is born to improve the application of hot air blower.
Introduction of plastic dehumidifying drying
dehumidifying dryer is generally used in the production of precision plastic products. It dehumidifies and dries the raw materials with strong hygroscopicity, such as PC, PET, PLA, PA, PMMA, etc., so as to avoid the problems of bubbles, water lines, poor light transmittance, etc. and ensure the high molding quality of products.
So what’s the difference between dehumidifying dryer and standard hopper dryer?
Standard hopper dryer
Standard hopper dryer has low cost and easy operation. It is suitable for most production with less strict requirements on appearance. Suitable for shell parts such as ABS, PE, HDPE, PP, etc.
dehumidifying dryer
dehumidifying dryer can effectively improve the shortcomings of ordinary dryers. It firstly draws in ambient air to remove the moisture in the air at a low dew point, and then heats and transports the dried air to the dryer to dehumidify and dry the materials, which greatly improves the working efficiency and reduces the drying time, and the drying effect is excellent.
Commonly used in PC, PET, PLA, PA, PMMA and other materials with strong hygroscopicity.
Crystallizer
Many engineering plastics, such as PET, PLA, etc., need not only dehumidification and drying, but also crystallization. Ordinary dehumidification dryers can only dehumidify and dry, while crystallizer can help the plastics crystallize while dehumidifying and drying, which is powerful. It is widely used in plastics, chemical industry, optics and other industries. Its characteristics are high crystallization drying rate, low energy consumption, keeping the physical properties of raw materials and high product molding quality.
All-in-One dehumidifying dryer
It integrates drying, dehumidification and transportation, and the one-piece design ensures that the materials are dried in a completely closed system, which prevents the dried materials from regaining moisture due to contact with outside air, and achieves a good drying effect.
Microcomputer PID control system, with over-temperature protection, motor overload, motor reverse protection, shutdown delay cooling and other protection functions. You can also choose PLC system. Dry air with low dew point and dew point below-40 C can ensure that the materials are fully dried.
The choice of all-in-one dehumidifying dryer should consider the material correspondence and other issues, so as to ensure that the raw materials are fully dried and dehumidify and dry efficiently.
