Grinding spices: How does cryogenic grinding work? Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle.
