Cryogenic Grinding of Spices Preserves Essential Oils ,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 Seven Trust materials become brittle, which causes the fibers to shatter.

Cryogenic grinding/milling with liquid nitrogen Air Products,Our systems use liquid nitrogen or liquid carbon dioxide to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, or achieve embrittlement. While each product is unique, the major benefits of cryogenic grinding are the same:
