Abstract

A conching device comprising at least one rotor shaft (4) having conching tools (5) is subdivided by partition walls (10, 11, 12) into compartments (13-16), so that in these compartments (13-16) different formulations can be conched simultaneously. The through holes for the rotor shaft (17) across the partition walls (10, 11, 12) between the compartments (13-16) are sealed by means of Belleville spring washers (18) such that no transport of chocolate paste can take place from one compartment (13-16) to another. Since the conching device comprises only one driving mechanism 8 and only two bearing units (6, 7) for each rotor shaft (4), there results a cost- and space-saving device, which can be employed in a manifold way. Thus, different formulations can be conched in the different compartments, which formulations can be processed parallely or at different times, by way of example.
