Cryogenic Grinding is the technique of pulverizing spices and herbs at subzero temperatures 17.78C, to minimize the loss of essential oils. Using liquid Nitrogen vapour blanket or Nitrogen gas circulation, a dry and cold atmosphere is created which does not react with the spices.
Suitable Lab Mills for Cryogenic Grinding. A number of aspects have to be taken into consideration while selecting a suitable laboratory mill for cryogenic grinding. While, the sample volume is critical for the decision, the feed size and preferred final fineness are important factors as well.
Singleuse vials of 1.5, 2 and 5 ml are also available for cryogenic grinding when it comes to sample amounts below 0.7 ml. Due to the high energy input and the resulting frictional heat, the grinding process should not take longer than 2 minutes to prevent the sample from warming up and to preserve its breaking properties.
Implementation Cryogenic grinding usually starts with chips or a fine crumb. This is cooled using a chiller. The rubber, while frozen, is put through a mill. This is often a paddle type mill. The Best Practice on Cryogenic Grinding covers this process in detail. The final product is a range of particle sizes
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.

and cryogenic grinding would help to understand grinding phenomena and develop efficient grinding system. It was established that cryogenic grinding produced Gelucire 4414 in a powder form and did not change its physical properties, emulsification capacities and dissolution performances of the formulation 5. Normal grinding produces poor quality
cryogenic grinding processes. I am sure cryogenic grinding is a growing market, especially in areas such as rotomoulding materials, hotmelt adhesives, powder coatings and recycling, says Bertling, and this facility will provide independent advice, with no bias towards particular manufacturers. If the economic gains to be had
Limits of Cryogenic Grinding We at Spectra Cryogenic Systems Pvt. Ltd recommend that you discuss your grinding requirement with one of our specialists before selecting any Grinding System. If there is any question about whether a material can be ground in a cryogenic system we will request that a portion be submitted for testgrinding.
