2021-12-1 Grinding is an age-old technique of particle size reduction to produce powders that can be used as intermediate or end products. Grinding aims to reduce the size of the particle by mechanical means such as impact, compression, shear, and cutting (Sahay and Singh, 1996).Hammer mill, plate mill, ball mill, pin mill, roller mill are commonly used grinding

Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle. The spices and foodstuffs remain free-flowing and are much easier to grind. Cold grinding avoids the undesirable rise in temperature caused by the electrical energy of the mill motors and ensures high product quality.
