Cocoa Butter Filtration

With this new concept, the old-fashioned horizontal cocoa butter filter cloth press has been replaced by a fully automatic cocoa butter filtration system. The new cocoa butter filtration system makes manual cleaning redundant and virtually eliminates manual labour. The fully automatic cocoa butter filtration consists of a pressure vessel with vertically suspended filter elements on the inside. During the cocoa butter filtration process unfiltered cocoa butter is pumped into the pressure vessel; while being pressed through the system the fixed particles remain on the outside of the filter cloth. Compressed air is used to automatically clean the filter cloths. The deposit (slurry) falls to the bottom of the vessel and is subsequently pumped to the liquor tank. After cleaning the system is ready for a new filtration cycle.
