    17/04/2020· 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,also known as freezer milling/ freezer grinding/ cryomilling is the act of cooling or chilling a material and then reducing it to smaller particle size. Almost all materials embrittle when exposed to low temperature. Cryogenic size reduction utilizes the cooling effect of liquid nitrogen to embrittle materials prior to and or during the grinding process. Materials which
