Product Outline

Vacuafluid Disk (NVD) is a disk dryer with single shaft especially for vacuum drying.
Indirect heat generated from disk and jacket efficiently contributes to drying powder at a low temperature, making use of powder fluidization generated under vacuum environment.

Application

Unit Operation
Drying, Solvent recovery, Reaction
Raw Material
Synthetic resin powder, Chemicals, Food

Features

Boiling point drop

¨

Heat weak material is dried continuously

Vacuum drying

¨

Continuous process is maintained with newly developed valves focusing simple charge/discharge
