The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly ...


Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle. The spices and foodstuffs remain free-flowing and are much easier to grind. Cold grinding avoids the undesirable rise in temperature caused by the electrical energy of the mill motors and ensures high product quality.


The optimum solution for these types of materials is cryogenic grinding. It involves embrittlement of the material with dry ice or liquid nitrogen which substantially improves the breaking behavior.

Cryogenic grinding – starting with rubber that has been coarse ground to two-inch minus, it can produce a fine grind, ¼ inch minus to 30 mesh, in fewer steps at a rate of 4,000-6,000 pounds per hour. In this method, liquid nitrogen is used to freeze the rubber, which is then "shattered" as it passes through a hammer mill. ...


Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model). A normal mill that works at more than 5000rpm needs cooling by water, air, special bearings etc. On the other hand, in cryogenic lines it is possible to reach 30,000 rpm with one or two motors, achieving a finer ...
