Abstract

In a batch method for the heat treatment of particulate solid material, especially food materials, the vessel in which the heat treatment takes place is essentially a jacketed pressure vessel (1) in which the material is tumbled while being heated, and in order to obtain an increase in throughput the solids and cooking liquor are removed to a second vessel (2) after cooling. In the second tumbling vessel there is a reversible strainer (12) which is used in the position illustrated to separate the liquor from the solids and then inverted after withdrawal of the liquor so that they may be blended with a different liquor, such as a sauce, introduced via a line (14).
