Cryogenic grinding technology retains colour, antioxidant activity, aroma and flavour properties of the materials thereby improves the product quality. ... As the cost of raw materials and energy is increasing day by day, it is very necessary to make its efficient use to get quality spice at a reasonable cost. ...
Some benefits of cryogenic grinding is that it is extremely dry, imparts no impurities on materials and eliminates any possibility of surface oxidation. Ground material can reduce compound costs, reduce blistering, and reduce mixing time, increase extrusion rates, and provide "value" from recovering companies own scrap instead of incurring ...
The cryogenic size reduction process, also known as "cryomilling", involves exposing the resin pellets to temperatures of -100° Centigrade or lower. These temperatures lead to finer grains, as they make even the most elastic polymers more brittle. This environment also suppresses recovery and recrystallization.
It is only efficient or cost-effective for certain ones. But for those specific materials it produces superior results. Cryo grinding is effective for grinding flexible and organic materials—such as commercial food products and many polymers—that embrittle only at cryogenic temperatures.
Cryogenics is the study of the production of very low temperature (below −150°C, −238°F or 123K) and the behavior of materials at those temperatures. Similarly, cryogenic grinding is a term ...
Feb 07, 2016· 6. Here comes the necessity of CRYOGENIC GRINDING …..also known as Freeze Grinding. 7. For pulverizing many materials, Cryogenic Grinding Technology increases productivity & lower power cost. Many elastic {or} "soft" materials are very difficult to pulverize (crush to fine particle),requiring long cycle times & high power/energy ...

In order to grind tough and elastic materials with a high throughput into fine powder, an efficient cryogenic cold grinding system is required. The feed material must firstly be cooled with a suitable refrigerant such as e.g. liquid nitrogen to a defined temperature usually below the glass transition or softening temperature to cool.
Cryogenic grinding is a process of mixing Liquid Nitrogen with a spice to lower the temperature up to -190 degrees C then grinding the super-cooled product. This type of grinding system protects spices essential oils and other vital constituents that could be lost during conventional grinding.
May 21, 2018· Cryogenic Grinding has its own advantages like less maintenance, no cooling agents required, low torque motors can be used for grinding, dimensions of the particle can be controlled but there are some demerits of this process like cost, the hazard of fuels, dry atmosphere is required etc.
