Cocoa processing

Cocoa processing begins with grinding the cocoa beans to liquefy the cocoa butter inside them. This first process produces a thick paste called cocoa paste. The cocoa paste is pressed to obtain cocoa butter. The part remaining after pressing, called the cocoa cake, can be turned into cocoa powder in a further grinding process. Processing cocoa beans therefore produces cocoa paste, cocoa butter and the cocoa cake, which are then mixed with other ingredients to make chocolate.

Costacurta’s wire cloth filtering disks are used in the cocoa paste pressing process. The machines used in this process are cocoa presses. These are hydraulic presses that compress the cocoa paste at a high pressure against a metal filtering disk. The high pressure causes the cocoa butter to liquefy, which is then separated by the filtering disk and collected. The result of this pressing is the separation of the liquid cocoa butter from the cocoa cake.

The wire cloth filtering disks are made by Costacurta in stainless steel to guarantee the highest level possible of cleanliness and hygiene. In addition, they are plasma cut in order to minimise the risk of pieces of wire coming loose. The use of suitable raw material also allows the machine operator, thanks to the action of special magnets, to remove any metal particles present in the cocoa powder.
