Hosokawa Micron further develops Mikro ACM mills
New developments in design have made the Mikro ACM mills from Hosokawa Micron even more suitable for the processing of heat and flavour sensitive products such as high-grade cocoa powder or chocolate crumb.
The Mikro mills can be used across almost the whole field of fine and micro-sized size reduction of products up to a hardness of 4 Mohs but their high air throughput, material flow and gentle comminution make them particularly suited to chocolate powder and crumb.
With an internal air classifier, the impact mills are capable of fine grinding without creating excess ultrafines. The ground product has a steep particle size distribution curve and this can be tailored to suit the application by adjustment of grinding conditions and the air classifier speed.
New developments of the Mikro ACM include the direct cooling of the grinding chamber which now means cocoa with a fat content of 26% can be milled without risk of product degradation. This high fat cocoa cannot be processed with pin mills, but the Mikro ACM, air classifier mill can achieve the requested fineness of 99.7 up to 99.99% < 75 µm. Reduced maintenance and cleaning intervals now mean there is even less risk of microbial contamination. Designed as a closed loop system, the air quality remains constant and resulting low air humidity prevents condensation forming.
