Processing Cocoa - International Cocoa Organization

Typically, the separation or pressing process begins by pumping hot cocoa liquor (200 degrees Celsius) into a horizontal hydraulic press with operating pressures of up to 550 bars. The cocoa cake formed from this pressing operation is then broken and milled to specified particle sizes as determined by end use. 9. Cocoa grinding
