A method of and apparatus for continuously processing substances containing cocoa butter or similar fats, especially chocolate masses, in a tempering machine with several stages of cooling on cooling surfaces followed by stages of heating on heating surfaces. The mass is supplied through mass chambers, in which it is stirred by powered impellers, to the cooling stages and to the heating stages. A cooling medium flows through cooling chambers adjacent to the cooling surfaces and a heating medium flows through heating chambers adjacent to the heating surfaces. Enough cooling medium flows through the cooling chambers to generate turbulence. The mass in the mass chambers is stirred powerfully enough to thoroughly blend it. The mass is removed from the cooling and heating surfaces without being touched by the mixing impellers in an operation that involves a shearing gradient in the cap between the cooling and heating surfaces and the mixing impellers of from 500 to 4000 sec-1.

Tempering machine for substances containing cocoa butter and similar fats, particularly chocolate masses, comprising: at least one mass chamber with mixing and stirring elements and a cooling stage having heat-exchange surfaces; a cooling circuit with a cooling medium therethrough connected to said cooling stage, said masses being cooled through heat exchange at said heat-exchange surfaces; a heating stage with heat-exchange surfaces; a tempering circuit with a tempering medium connected to said heating stage, said masses being reheated after being cooled through heat exchange at said heat-exchange surfaces of said heating stage; said heat exchange surfaces of said heating stage being at least 40% of the sum of said heat-exchange surfaces of said cooling stage and said heating stage for maintaining a constantly regulated temperature of the heat-exchange surfaces of said heating stage.
