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 allows products to be ground and crushed at a lower level of stress, depending on the hardness of each product, causing in lower energy output. Since less energy is used, there is an even amount of pressure used during the grinding process. This results in a higher quality product that is more fine, uniform, and has an ...

Cryogenic grinding is the act of cooling or chilling a material and then reducing it into a small particle size. Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate cryogenic recycling of tough composite materials and multi component scrap. The term "cryogenics" originates from Greek word which means creation or production by means of cold.

Cryogenic grinding of plant and animal tissue is a technique used by microbiologists samples that require extraction of nucleic acids must be kept at 80 c or lower during the entire extraction process for samples that are soft or flexible at room temperature cryogenic grinding may be the only viable technique for processing samples design of a .
