The DB series cocoa bean debacterisation system operates on the whole product as the bacterial flora is only found on the surface of the skin.Roasting the whole bean immediately after processing preserves the aromatic characteristics of the chosen cocoa.The system consists of two vertically stacked conical tanks communicating through a tube equipped with two valves ensuring perfect isolation.The quantity subject to treatment goes to the upper tank meant for whole cocoa beans receipt. As the reactor of the process the lower tank receives the right dose of product, maintains its agitation and treats it with overheated pressurised vapour for a relatively brief period which is, however, sufficient to reduce the bacterial load to the minimum.At the end of the process, the sterilised cocoa beans flow out of the debacteriser, creating a batch tracking system that continuously feeds the next roasting stage.
