Disc Dryer

A Haarslev Disc Dryer is the ideal solution for removing as much water as possible, as gently as possible, from coarser fish, animal or poultry by-products with a low fat content. Designed to use steam pressures of up to 10 bar, these dryers have become the solution of choice for coarser inputs featuring lower fat levels, because they make use of the natural fatty content in the material.

These sturdy, reliable units are built around a rotor consisting of a central shaft fitted with multiple steam-heated discs. These apply indirect heat over a very large area, in a compact design that quickly and effectively removes the evaporated water vapor. This means as much heat as possible gets transferred to the material in the dryer.

The dried material is discharged at the bottom, using a screw conveyor fitted with variable-speed drive. This can be adjusted independently of the dryer itself, providing maximum flexibility.

Vacuum drying configurations are also available to provide exceptional end-product quality.

Applicable for
Defatted animal by-products such as meat and bone
Defatted fish by-products
Hydrolyzed feathers
Mechanically dewatered blood

Benefits
Relatively large heating surface provides exceptional evaporation in a compact design
Good control of load level inside the dryer, making sure the rotating discs transfer heat as efficiently as possible
Effective heat transfer because condensate is removed quickly
Full control of drying processes enables you to boost yield and product quality
Exceptional reliability and long service life thanks to cool-running, oil-lubricated bearings
