Cryogenic grinding Generally speaking, CO 2 or LN 2 are used as the cooling agents. The product and system are cooled either by direct injection of the cooling agent into the mill or, if longer residence times or lower temperatures are necessary, by precooling and embrittlement of the material in a screw cooler. Enthalpy CO 2 330 kJ/kg (-20°C)

Wide-chamber mill for additive manufacturing

The CW-II product line has been given a substantial redesign to make it fit for the demands posed by cryogenic size reduction of difficult feed materials. Two contra-rotating pin discs rotate in the mill at speeds of up to 120 m/s each at their outer periphery, allowing relative speeds of up to 240 m/s to be realised.

Cryogenic grinding prevents spices from heating up during grinding and causing the essential oils to volatilise and heat-sensitive fats to melt. In the worst case, this can lead to the grinding elements clogging up and the mill blocking. Cryogenic grinding therefore optimises both the product properties and the process management.

Cryogenic Temperature: Everything You Need to Know CTP

Oct 29, 2020 The cryogenic temperature range is defined as from −238 °F to −460 °F, which is absolute zero, the point where molecular motion is as close to theoretically possible to stopping completely. Temperatures above −238 °F can, therefore, not be considered cryogenic. Any treatments applied at such temperatures won’t qualify as cryogenic
