Thin-film dryers

Transfer heat through the equipment surface

Thin-film dryers use a heated wall and rotor to distribute the product. In the vertical design, hinged blades spread the incoming wet material as it moves towards the solids outlet. The process removes vapour while developing the required dried-product condition.

Handle changing product consistency

Horizontal thin-film dryers can process feeds that pass through a sticky or pasty phase on the way to a solid. The manufacturer offers operation under vacuum, at atmospheric pressure or under pressure, depending on the design. The photo illustrates horizontal equipment.

Configuration note. Construction and process conditions must be selected for the feed and final product. A common throughput or temperature rating does not apply to the whole range.
