Low-temperature freeze pulverizer is especially used to pulverize oily materials and materials with high sugar content into granules or powder. Freezing pulverizer machine is a cryogenic mill derivative products, compared with small size, low consumption, low energy consumption, easy operation, is the first domestic set of output and energy saving in one mill. Widely used in food industry, medicine industry and polymer materials testing.
Nowadays, the liquid nitrogen mill has played an increasingly important role in industry. It mills the samples that are difficult to pulverize at room temperature, especially to heat sensitive products, including plastics and foodstuffs.
Liquid nitrogen frozen pulverizer consists of screw feeder, grinding parts, cyclone separating part, blower, electric control box and supporting frames. is a special design combined pulverizer machine with liquid Nitrogen. The grinding room is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. The liquid nitrogen circulates through the system and is continually replenished from an auto fill system in the exact amount. The temperature can be cooled down to -196°C, which can be adjusted according to the brittleness point of different stuffs. Thus the material is embrittled and volatile components are well preserved. Powerful impact blade lead to a perfect grinding efficiency. Then pulverized into powder and very fine powder inside the grinding chamber and discharge from the cyclone separator. There is no dust flying during the whole process, clean and healthy, easy to maintain, made of stainless steel. Admittedly, the auto filling system avoids direct contact with liquid nitrogen and makes the operation very safe.
Closed loop design, energy saving
Unique pulverizing design and compact space usage
Mesh size adjustable from 10-700mesh
more uniform particle size distribution
process cooling/temperature control
frequency conversion control system is used in the whole system
Can solve the crushing process of materials that can not be pulverized under normal temperature
All speed of motors can be adjustable to reach a better crushing effect
engineering plastics, nylon series product, polyester series product, polypropylene series product, polythylene series product, thermal plastics, hot melt adhesive, thermal sensitive products, natural rubber,etc. liquid nitrogen mill /cryogenic mill is widely used in grinding PP, EVA, TPU, TPEE, nylon,PA11, PA1010, PA12, PA6, PA66, PA610, and so on.
Spices and seasonings, chili powder, pepper powder, food additives (sodium alginate powder, xylitol powder, sorbitol powder), fatty mixtures, baking agents, pure coffee, mustard seeds, star aniseed, full-fat soya beans,etc.
medicine, drug and Chinese herbs (includes root, branch and block)
Materials rich in oil and sugar:
for example, chili, pepper, coriander seeds, cumin seeds, fennel seed, aniseed, cinnamon, walnut, red date, jujube, Chinese wolf berry, hawthorn, medicine, rubber, plastics, and many other fatty materials.
The grinder adopts liquid nitrogen as cooling medium, it can preserve the material which will not change the original composition.
And Cryogenic pulverizer can crush some special . Different materials may have different characteristics and crushing fineness, so please send your inquiry to us before choosing frozen pulverizer.
