    Cryogenic grinding is a method of powdering herbs at sub-zero temperatures ranging from 0 to minus 70°F. The herbs are frozen with liquid nitrogen as they are being ground. This process does not damage or alter the chemical composition of the plant in any way. Normal grinding processes which do not use a cooling system can reach up to 200°F.

  • Cryogenic grinding: an independent voice

    True cryogenic grinding is a different process designed to exploit the tendency of many materials to become brittle at low temperatures. In grinding plastics and rubbers, for example, the stresses needed to break up the material are dissipated by relaxation. As a result, plastics need 10–100 times as much energy to grind as inorganic materials, or typically 1 0 0 – 1 0 0 0 kWh/t at room ...
