Cryogenic Grinding System Cryogenic size reduction (grinding) of spices is an acceptable technique that helps to retain the natural quality of spices. Welcome to Spectra Cryogenic Systems Pvt. Ltd. Introduction Cryogenic size reduction (grinding) of spices is an acceptable technique that helps to retain the natural quality of spices.

Cryogenic grinding solutions have historically been used for specialty or hard-to-grind and heat sensitive materials. However recent advances mean that they can be employed to create ultra-fine particles used for the manufacture of high-performance polymers and plastics.

The use of cryogenic technology for spice grinding is a scientifically proven technique with less loss of volatile content and improved color and grinding operation. Liquid nitrogen is employed to provide the refrigeration needed to pre-cool the spices and maintain the desired low temperature by absorbing the heat generated during the grinding

A pin mill or grinder was employed for grinding the black pepper under ambient and cryogenic conditions. The mill was obtained from Hosakowa Alpine (Germany) with a grinding capacity of 80 kg hr −1 and it was run by a three phase 3.7 kW motor. It consisted of two rotors (one stationary while the other was rotating) with a number of cylindrical stainless steel pins of 4 mm diameter affixed on
