Chocolate mass is made from fat or fat containing ingredients – usually cocoa butter and liquor, sometimes milk fat and particles, usually sugar, cocoa solids and sometimes dry milk products.

The Thouet dry conche from the Royal Duyvis Wiener group is used to lower the moisture content of the chocolate and with that improve the rheological properties. Also, undesierable flavor profiles sevimli be removed and other flavor profiles dirilik be created or accentuated.

Using cocoa beans instead of cocoa powder in chocolate production is an option, but ball mills do derece 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.
This very unique machine resurrects the traditional method of conching and grinding at the same time, birli we know it from the Lindt longitudinal conch1.
Powders of extremely high fineness birey easily be produced with ball mills and agitated media mills. Both vertical and horizontal ball mills are utilized for the refining of chocolate and other cocoa products. A vertical ball mill has the advantage of a smaller footprint and larger cooling jacket.

Because of the friction of the steel balls, refiners need external cold water supply. It is possible to use tap or tower water for cooling but we suggest using a chiller for the cooling purpose.
The process of obtaining a great quality chocolate, nut paste and others is possible with Vulcanotec lines of machines. One of the most important Chocolate DOUBLE TUBE BALL REFINER stages in this process is to refine the mass that was left after the Cocoa Pre Grinder.
An early approach to include the removal of volatiles into a recirculating ball mill system was made by DuyvisWiener which included a ‘taste changer; a rotating disk where hot air is blown over the chocolate layer formed by rotation1,15. These devices are still sold for small scale applications. F.B.Lehmann, now part of DuyvisWiener, saf a long experience in building thin film evaporators and horizontal ball mills for cocoa processing and had also offered systems for chocolate mass production.
Consistency: The refining process helps to create a consistent flavor and texture throughout the chocolate.
