Cryogenic Grinding of Spices Preserves Essential Oils

Mar 25, 2018· The cryogenic grinding system consists of two units, Pre-cooling Unit, and Grinding Unit. These units introduce liquid nitrogen into the barrel and remove the heat from the material before it enters into the grinder. By the use of low temperature, the raw materials become brittle, which causes the fibers to shatter.
