Hot Air Dryer for Plastic

Hot Air Dryer for Plastic

In China ECOTECH factory, hot air dryer for plastic means the desiccant rotors which require the hot air with around 160℃-180℃ to recuperative when moisture being matured adsorption. Hot air dryer for plastic usually used in plastic dehumidifying machines.

Plastic products have very high requirement to air desiccant standard. Almost all plastic materials have the characteristic of hygroscopicity. PA, PET, PC, PBT, Ca all are hygroscopic materials. Plastic raw material particles are shaped by heated and kneaded.

As the ambient temperature gradually rises, water evaporates, leading to an increase in ambient humidity. High humidity will lead to the plastics products with many problems of bubbling, cracking, speckle marks, poor transparency and these defective phenomenon.

Therefore, to solve these problem need to find the answer from the root, that is to lower the humidity of the air, and let the air be almost completely dry. To reduce air humidity, the most ideal measure is to use the hot air dryer for plastic. In the actual manufacturing course, honeycomb rotary hot air dryer for plastic is an essential equipment.

Our molecular sieve honeycomb rotary hot air dryer for plastic can reduce the air dewpoint to below -40℃ and make the heat to blow over the surface of wet-containing plastic particles, that can reduce the moisture content of plastic to below 0.02% before molding, thus improving the quality of finished products. And meanwhile the hot air make the dryer being reactivation.

The working principle of hot air dryer for plastic is using the molecular sieve in the glass fiber cellular to capture the wet air of moisture and storage them in the rotary rotors, then the stored moisture being removal by the hot air. The dryer always slowly run with very small power.

These Hot air dryer for plastic, our market shares is around 75%-80% in China. Specialized in making all kinds of different specification air dryers for industry dehumidifying to get the super desiccant air.
