Most of the engineering plastics are hygroscopic. When the plastic is taken out of the moisture-proof sealed packaging bag and exposed to the atmosphere, it begins to absorb moisture from the atmosphere. If the general traditional hot-air bucket dryer is used, it can not prevent the plastic from continuously absorbing moisture because it uses the external air with moisture to dry the plastic.


   with the wide application of engineering plastics, the dehumidification dryer has gradually replaced the traditional hot air dryer.


   classification


   the application of dehumidification dryer can be divided into single machine and centralized. Single machine dehumidification dryer generally includes dryer host, drying barrel and suction machine. The application of single machine is suitable for a few and diverse drying. Its advantages are good drying power and convenient rapid refueling.


   the centralized dryer includes a dryer host and several drying barrels. Each drying barrel has an independent heating controller, which can dry several different raw materials together, and cooperate with the air volume control valve to control the air volume of each drying barrel.
