From Cocoa Press Cake to Cocoa
Finely-ground cocoa liquor is separated into liquid cocoa butter and solid cocoa press cake in a chamber filter press.
While the cocoa butter is filtered and discharged in liquid form or into blocks, the compact cocoa press cake is pre-milled in roller crushers and then dry-milled into finely-ground cocoa powder.
NETZSCH can offer various machine types for pulverizing the pre-crushed low fat or high fat cocoa press cakes depending on their fat content, feed temperature and desired final fineness.
