Modeling of granular heat transfer in cryogenic grinding ...

Abstract In the case of grinding of spices, the cryogenic counterpart is commonly used for obtaining a high-quality spice powder retaining the maximum thermo-sensitive flavoring compounds; however, the operational cost restricts its industrial application. Therefore, in a cryogenic grinding system, an insight into the micro-mechanical behavior and heat transfer phenomena of the granules is ...
