Seminar On Cryogenic Grinding Report Download

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.

Mechanical Disruption Methods: Grinding

Limitations – A significant problem in cryogenic grinding with mortar and pestle is that small samples (e.g., 10-20 mg) can be essentially lost when ground into the surface of the mortar. This makes sample recovery difficult and leads to poor yields. Another major disadvantage of mortars and pestles is that the number of samples that can be ...
