Cryogenic grinding of spices is a method of powdering spices/herbs at sub zero temperatures ranging from 0 to minus 196 C. The spices are frozen with liquid nitrogen, as they are being ground. This process does not damage or alter the chemical composition of the spices in any way.The effect of cryogenic cooling in the grinding of PEEK was studied and compared with pressurized air cooling. The ground surface quality, cutting forces, and tool loading are investigated. The ground surface quality was profoundly affected by the cryogenic cooling. The cryogenic cooling led to superior surface quality.The effects of cryogenic cooling on the grinding process of

Cryogenic size reduction utilizes the cooling effect of liquid nitrogen to embrittle materials prior to and or during the grinding process. Materials which are elastic in nature, which have low melting points, which have low combustion temperatures and which are sensitive to oxygen can be ideally machined by cryogenic grinding process.For example, cryogenic grinding under the protection of liquid carbon dioxide or liquid nitrogen gas helps to retain flavor substances and improve the flavor quality of product powder (Karam et al(PDF) Cryogenic Grinding: a Physical Technique to Retain Volatile
