ABSTRACT:
The invention concerns an apparatus having a cylindrical tempering column comprising a cooling stage and a subsequent reheating stage for continuous tempering of a fat-containing, chocolate-like mass. A plurality of interconnected mass chambers are separated by intermediary heat exchange chambers. The mass chambers comprise mixing and stirring elements (8) with radially extending, plate shaped arms (11) comprising plate shaped mixing blades (13, 14, 15, 16; 17, 18, 19, 20). According to the invention, an opening (24) for flow of the chocolate mass therethrough is arranged in the plate shaped arm (11) at a part of the arm located between the inner mixing blade (13; 17) and the hub. Hereby is provided an axial flow of the mass close to the drive shaft, so that nests and zones of no stirring in the mass are avoided around the shaft, especially where the plate shaped arm is connected with the hub. The total surface area of the plate shaped arms (11) and of the mixing blades (13, 14, 15, 16; 17, 18, 19, 20) may decrease gradually in direction out towards the peripheral cylinder wall. Hereby is achieved a considerable more uniform stirring of the mass at all areas of the chamber followed by an enhanced heat transport in the mass than was possible with the prior temperers.
