Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.
produced during the grinding process can result in a finer, more consistent particle size distribution and higher throughputs for many products compared to conventional grinding methods. These products include adhesives and waxes, carpets, color concentrates and pigments, composites, grains, pharmaceuticals, plastics, powder coatings, metal, multi-

On the other hand, the duration of the grinding process should be kept as short as possible, because the material to be ground, which is heated again by the energy input of the grinding tools, should not be deformed but be grinded. The objectives of the cryogenic milling of thermoplastics and elastomers are:
From spices to thermoplastics, cryogenic size reduction can provide benefits to a variety of industries. Cryogenic size reduction can provide benefits for many processing appli ions, including spices. Liquid nitrogen LIN has been used for more than 30 years in cryogenic grinding to “super-refrigerate” size reduction processes in industries such as food processing, plastics recycling
Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 C or lower during the entire extraction process. For samples that are soft or flexible at room temperature cryogenic grinding may be the only viable technique for processing samples
This process is described as cold grinding or cryogenic grinding. In cold grinding, the substance is cooled down by adding cryogenic gases, such as liquid nitrogen, and is therefore easier to grind.
Industrial hemp and its cannabidiol CBD derivatives have pushed to double-digit growth rates in the last few years, bringing with it substantial growing pains. New, efficient methods for growing, harvesting, processing, testing and packaging industrial hemp are needed — in addition to quality requirements and standards — to meet the escalating demand for this product.
