Trends in Grinding of Agroindustrial Products-A Literature Review

It is observed that engineering texts dealing with theoretical and analytical food milling operations do not emphasize the new trends found. As a complementary part of this study, eight patents related to cryogenic grinding in food were analyzed, identifying uses of this type of grinding in coffee, lipids, lycopene, proteins, grains, and seeds. Besides, a search was carried out to find out commercial suppliers of cryogenic grinding equipment, in which six companies from China with their equipment were identified.
