CONCA CR

CR150 – CR300 – CR600 – CR1000 – CR2000

CONTINUOUS AND GENTLE CONCHING

Conching machine mod. CR, CR150, CR300, CR600, CR1000, CR2000, had been designed for satisfying at best chocolate aromatic ‘transformation’.

In addition to cocoa mass conching, there is the possibility of loading other ingredients of the recipe.

Through the continuous mechanical movement, exerted by the special stirrers inside the tank, the cocoa liquor is slammed on the walls of the tank. Favoring product aeration, moisture and residual acidity extraction.

Process

PLASTICIZATION: that is to say the transformation of the product from lumpy into fluid through considerable ‘cutting’ efforts effected by a special horizontal agitator driven by a powerful motorization. In this phase air around solid particles are eliminated allowing the union with cocoa butter.
DEHUMIDIFICATION and ACIDITY EXTRACTION: in this phase, the humidity and acetic acid (due to cocoa beans fermentation) are extracted from the product. With the progressive water elimination, viscosity is gradually reduced. This phase strongly affects the creation of the aroma and fluidity of the end product.
AROMA’S DEVELOPMENT: by submitting the product to a continuous aeration, some reactions occur (Maillard reaction) which cause the transformation of many compounds present in others having pleasant taste. The continuous homogenization of the product inside the conching machine, keeping a constant temperature in addition to the listed process, it allows to get a global equilibrated aroma.
