Pre-refining is widely employed by most chocolate producers, as it offers remarkable advantages. The input products are semi-liquid fatty masses with an average particle size distribution of approximately 500μm (measured by micrometer) and containing less than 1% solid particles with a maximum size of approximately 4mm.

The output product is a homogeneous mix with an average particle size distribution of 120-220μm, measured by micrometer, suitable for being fed into the successive refining line. By integration of the pre refiner into the line the mixing time can be easily reduced.

SACMI HCP series machines, equipped with various rolls size guarantee the required capacity. The discharged chocolate mass is homogenous in particle size and fluidity and that ensures the proper functionality of the following refining machine.
