APPARATUS FOR COUNTERCURRENT HEAT TREATMENT OF BIOLOGICAL TISSUE

摘要

A device and a method for a continuous heat treatment of biological tissue material that may or may not be disintegrated, such material comprising, e.g., fish, wherein the material is treated with heat in countercurrent to the material flow using a vertically arranged container provided with at least one vertically arranged shaft mounted for rotation. The shaft is provided with stirrers each having a vertical and helical pitch and being adapted to work the material zone by zone in vertical and horizontal directions.
