Wedge Style Dryer

Wedge Style Dryer.Conduction heat transfer type dryer

The wedge style dryer is a conduction heat transfer type of dryer. A heating medium such as steam, hot water or oil passes inside wedge-shaped rotary blades and also through the jacket of the dryer main unit.
The wedge style dryer efficiently dries the processed materials up to the specified moisture level via heat transfer from the rotary blades and jacket.
The moisture evaporated from the processed materials is discharged together with the carrier gas.
This conduction method produces minimal exhaust gas, which enables a smaller exhaust gas processor to be used. This results in great advantages such as a smaller installation area and lower running costs.
