This machine is designed according to the characteristics of the natural cocoa butter and cocoa butter equivalent(CBE).Tempering machines are used to pre-crystalise the fat (cacao butter) contained in the chocolate, forming stable crystals of type ß and ß´ which provokes the acceleration of the total crystallization of the product, increasing visibly its brightness and shelf life and avoiding the formation of fat bloom and sugar bloom in the final product.It is in vertical structure,the chocolate mass is fed from the side, then passing through the temperature adjusting screw and output from the top of the machine. The screw is divided into four temperature sections.After this process, the chocolate products will be well crystallized with smooth taste, good finishing and longer shelf life.
