Title: Method of making chocolate and chocolate flavoured compounds
IPC: B01F13/10
Filed: 1977-11-25
Abstract: A pump (5) repeatedly conveys a liquid composition containing cocoa solids through a pipe system (3) to a grinding unit equipped with a bed of grinding bodies (12) in motion, between which the cocoa solids are comminuted, which are then returned to the pump via a pipe system. The conveying rate is such that at least 30 and preferably between 50 and 500 times a volume of the liquid composition is conveyed, per hour, through the grinding unit, the volume corresponding to the volume of the grinding unit which is not occupied by the grinding bodies and the stirring device. In this manner, chocolate or a chocolate-containing substance is prepared in which the particles are highly uniform in size. When carrying out the process, the temperature is controlled so as to expel undesirable components, such as acetic acid, while the desirable components are retained. <IMAGE>
