ECO2–Choc®

Conching before Grinding

ECO2–Choc®

The real alternative to the conventional chocolate process!

Unlike conventional methods, the process begins with conching in the powder phase, which enables the efficient removal of volatile substances such as moisture, ideal for high-quality chocolate products.

Thanks to this innovative process, the energy required for conching is reduced by up to 50%, making the process significantly more economical without compromising product quality.

A residual water content of ≤1% ensures a low viscosity mass at reduced fat levels thus enabling resource-saving grinding in agitator bead mills.
 

The system starts with the TRIQUENCE® mixer, which roughly conches raw materials and develops flavorings under the influence of temperature and shear forces. The mass enters a buffer mixer and then the desired fineness is set in the grinding process with the IMPACTOR® bead mill.
