spice flavor retains during grinding process. Definition: Cryogenic grinding of spices is a method of powdering spices/herbs at sub zero temperatures ranging from 0 to minus 196 0C.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.
ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
