Abstract
An autoclave-type reaction vessel has a mechanism for stirring and recirculating the cocoa solution, the mechanism having a greater mechanical performance which allows for an increase in the efficiency of the various processing steps, in particular via an increase in the water content of the solution. In a closed vat (1), stirring elements (32 to 35) are mounted on a hollow rotatable shaft (6) driven by a back-geared motor (7). Some of the solution is drawn off at the bottom of the vat by an external pump (36) which delivers it up the inside of the hollow shaft (6) to a spraying head (41). Processing fluids (48, 49) such as neutral gases and alkaline solutions may be added to the solution before it reaches the pump (36).
