VERTICAL SINGLE SHAFT DRY CONCHES WITH BATCH CONTENTS FROM 2000 TO 6000 KG FOR ABSOLUTE DRY CHONCHING AND LIQUEFYING

The vertical single shaft batch conche PVS is designed for high-quality chocolate formulations. This type of dry conche has an installed base of hundreds of machines worldwide and the concept is proven over years.

The special designed and precise machined conching tool with defined clearance between conching tool and the jacketed conching bowl guarantees a maximum energy input into the product and high shearing during the dry conching phase. Like the HBC conche, the conching shaft is driven by a variable speed drive.The conche PVS is additionally equipped with a spraying unit, sucks the chocolate from the bottom of the PVS conche and distributes the chocolate via a rotating disk in a thin film to the wall of the conche. In combination with an increased speed of the conching shaft a very good homogenization, deagglomerating and stabilization of the finished chocolate mass is achieved. The open and simple design as well as the precise machines clearance of the conche PVS offers a very good emptying of the conche with minimal product residues. This also minimized the cleaning and maintenance requirements.

Working Principle - two phase conching

• phase - dry conching and pre-liquefying
• Deacidification and dehydration of the mass coming from the five roll refiner
• phase - spray refining and final liquefying
• Deagglomerating, homogenizing and degas- sing of the pre-liquefied  mass
• Final liquefying of the constant agglomerate- free and homogeneous mass
