Working principle:

Dehumidifying dryer is put the dehumidifier and insulation dryer together to form a dehumidifying and drying combination. It is generally applied to further remove moisture from dried plastic particles,reduce the moisture content of plastic particles to the index which is reuqired by plastic proccessing . It working principe is the hot and humid air will blow into the honeycomb rotor which is return from drying bucket after cooling .The moisture is quickly absorbed by the melecular seive, then will be desorved by the high-temperature moisture which regernertived. These two air currents act simultaneously on the rotor.As the rotor rotates , the moisture in the air is continously absorbed and desorved and discharged, eventually forming a stable low dew point air,which is heated to the drying temperature required by the plastic material , and then blown into the drying bucket to forming a closed circulation loop.
