About Cocoa:

Cocoa Processing: Founded in 1885: Duyvis has developed into a key supplier for machinery in the food and especially in the cocoa industry. Innovative solutions and continuous (re-) development and engineering had made PM Duyvis tot the key supplier for machinery processing cocoa beans into cocoa-liquor-butter and powder.

Cocoa Butter: For more than 100 years Duyvis has been modifying, maintaining and overhauling cocoa butter presses of various manufacturers. Some 30 years ago Duyvis developed its own cocoa butter press. Today the Duyvis cocoa butter presses have proved to be the very best of their kind, capable of continous operation with a high capacity and an excellent output quality.

Cocoa Powder: The Duyvis powder installation is a complete system. Hot cocoa crumbs coming from the pressing  room are fed into the mill installation and come out as stabilized cocoa powder that can be stored without running the risk of lump formation or loss of colour.

Liquor Pump: Duyvis has designed a unique pump, capable of combining high flow capacities with high pressures. This liquor pump, developed and produced in-house by Duyvis, is operational under the most extreme conditions in the industry. The pump has been specially designed for transporting difficult-to-pump viscous and abrasive liquids such as cocoa liquor that require a relatively high pressure. The pump is largely used for filling cocoa butter presses at a pressure of 25 bar. As a result of the high pressure cocoa butter usually starts flowing during the process of filling before the actually pressing.

Grinding Line: The machinery manufactured by Wiener is well known to the cocoa liquor and chocolate industry. An estimated 40% of the world's cocoa bean crop is processed on the Wiener equipment worldwide.
