A Review on Cryogenic Grinding - Inpressco

2017-6-2  From the research it can be concluded that the cryogenic grinding process produces fairly smooth fracture surfaces. Little or no heat is generated in the process. This results in less degradation of the material. Apart from this Fineness and uniform distribution of particular sized particle is met in this process according to requirement; it can be adjusted using suitable configuration of Cryogenic grinders. As the production is in inert atmosphere the material is protected from oxidation and rancidity. Comparatively the cost of Cryogenic grinding

Cryogenic grinding was shown to significantly affect active constituent levels in herbs. Test results showed an average increase of 15.6% in constituents tested in four medicinal herbs when they were ground cryogenically. The range was 10.7% to 21.8%, indicating that some herbs are affected more than others by the temperatures at which

2021-2-15  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.
