Cryogenic grinding SEMINAR REPORTS FOR MECHANICALS

01-10-2009  Cryogenic grinding involves cooling a material below its embitterment temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture

Cryogenic Grinding Seminar Report, PPT, PDF for

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.

Mechanical Disruption Methods: Grinding

Cryogenic grinding is useful as a first step in preparing samples for chemical lysis or subsequent mechanical processing. Its true value is that samples can be reduced from large solid items to small particles without tremendous input of heat. With smaller particle size, the sample can be rapidly dissolved, as is done for RNA isolation.
