Abstract

Refining mill for cocoa, which is essentially characterized by being constituted by a set of grinding installable in the upper part of the bench of a final refining machine, the mill being integrated by a fixed and a rotating disk, both of stone, provided in its internal face of a radial groove and coaxially facing vertically with very little separation from each other inside a metallic envelope conveniently mounted on the general bedplate of said machine, in whose housing there are also the adequate fasteners and rotation of the rotating disk, such as screws, transmission shaft, bearings and corresponding electric motor, depositing, on the other hand, the cocoa to refine inside a front hopper that opens next to the central area of the fixed disk in which there is a frustoconical cavity lined inside with a wall of material harder than the stone that forms, the rest of the disc, whose cavity locates, at the same time, a stump solidary of the rotating disk that presents the own frustoconical configuration of the cavity in which it turns and of which it is slightly separated forming an interstice through which the cocoa is forced to pass, which remains , for this purpose, committed to a grinding that continues to be verified then within the gap that also exists between the vertical faces of both discs, from which the paste thus obtained descends, by gravity, by an appropriate lower nozzle that directs them towards the refining rollers of the machine.
