Chocolate Refining Machine - Ball Mill

Description

Ball refining is one of the chocolate micronization techniques. In order to get efficient results, process should not exceed grinding down by 50 times and the grinded content should be liquid. Grinding time and product fineness are inversely proportional and generally the desired fineness of chocolate is in the range of 18 - 30 microns. 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. RBM50 and RBM100 are designed for artisans and small workshops. LabBM10 is designed for laboratory use, product development or educational use. Machines are equipped with solenoid valve which automatically opens gate of cold water flow and ensures cooling of the equipment. Because of friction of spherical 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.

Auxiliary equipment

Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do not provide efficient results in grinding raw materials thicker than 1.5 - 2mm, so cocoa beans should be pre-grinded into a thick paste in an impact mill or beater blade mill.

Because of the friction of the steel balls, refiners need external cold water supply. It is possible to use tape or tower water for cooling but we suggest using a chiller for the cooling purpose.
