Ball refining is one of the chocolate micronization techniques. Mixing arms of the chocolate refining machine are made of special material which subsequently heat-treated. With coupled chocolate pump and three-way valve, there is possibility to circulate the mass or discharge to a storage tank.Machines are equipped with solenoid valve which automatically opens gate of cold water flow and ensures cooling of the equipment. Because of friction of spheric balls cold water is required from an external source which can be from tape, tower or a chiller. Machine will open cold water gate in case overheating and will close it when cooled.
