Two-roller dryer
Technology
Two-roller dryer
Gentle drying process
Roller dryers are used for the continuous drying of solutions, suspensions and pastes of various consistencies and viscosities.
The wet material to be dried is applied to rotating, heated hollow rollers in thin, even layers using special devices. The moisture evaporates during a partial rotation of the rollers. The dried product is removed by scraper blades and fed to the next processing stage via conveyor systems.
The ZETTL ROLLER DRYERS can be operated both under normal pressure and under vacuum. Thanks to ZETTL GmbH's many years of experience, roller dryers can be produced in almost any size and according to the customer's requirements.
