The Isoma Cocoa Bean Conveyor is a fully enclosed, inclined belt conveyor, developed to feed loose cocoa beans from the exit of the sterilisation unit, up to the roaster infeed located at high level.

​

It was designed and manufactured as a fully welded stainless steel construction and enclosed throughout its length with sealed, safety interlocked doors.

The conveyor also incorporates a full wash down CIP system (Clean In Place – rinse, detergent and disinfect), to meet strict hygiene requirements required by the customer.

 

In order to achieve a more efficient roast, the process requires any excess moisture on the cocoa beans to be removed prior to feeding into the roaster unit.

 

Therefore a pre-roast drying system was developed and installed by Isoma, where hot air is ducted into the fully enclosed conveyor, in separate zones along the entire length.
