This drier is designed following GMP norms and it has been conceived as a universal drier for all types of products. Heating is applied to the cylindrical body, doors, bottoms and filter. It is also possible to apply it to the shaft and blades, creating an additional dynamic drying surface area. The sealing of the agitator shaft can be obtained either by a packed seal or mechanical seal. In the sanitary version the shaft is cantilevered on the side of the front inspection and cleaning door.
