Hollow screw heat exchanger

For difficult cases of heat exchange with granular and pasty or medium viscous products that require continuous cooling. Use in almost all branches of industry, e.g. chemical-, pharmaceutical and aluminium industry.

Intermeshing hollow screws constantly deliver and thoroughly mix the product to be processed. The individual particles of the product repeatedly contact the heat exchanging surfaces of the hollow screw.

Max. heat exchange is achieved when the product is filled in up to the optimal filling level. Size and conveyance speed are depending on the transfer rate, the product to be transferred and installation position.
