Patent ID: 11452301

Abstract:
Disclosed is a method for processing cocoa beans or nibs comprising the steps of: (a) adding water to cocoa beans or nibs to form a suspension; (b) wet grinding said suspension; (c) subjecting said suspension to a heat treatment at a temperature of 70° C. or less; (d) separating the suspension into: a water phase (heavy phase), a fat phase (light phase) comprising cocoa butter, and a solid phase comprising cocoa powder and fluid components; (e) continuously separating the fluid components from the solid phase obtained in step (d) to obtain cocoa aroma and cocoa powder by supplying a flow of said solid phase to a mixing device; wherein the mixing device comprises: a cylindrical, tubular body with a horizontal axis having an inlet opening for the solid phase, an outlet opening for the dried solid phase and an optional outlet opening for a vapor phase comprising cocoa aroma; end plates closing the tubular body at its opposite ends; a coaxial jacket heating or cooling the internal wall of the tubular body to a temperature of from 55° C. to 150° C.; and a bladed rotor, which is supported for rotation in the tubular body, its blades being arranged as a helix and oriented for centrifuging the solid phase and simultaneously transporting it towards the outlet opening.
