Cryogenic Grinding Applicationscryogenic Grinding Of Spices

advantages of cryo grinding - aaamachine,ultra-fine particle grinding. ogl’s cryo grinding process produces much more finely ground particles than conventional milling methods. ogl cryo mills are able to grind many materials to 10µm average particle size or smaller. this improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid..hosokawa alpine aktiengesellschaft contraplex® pin mills,cryogenic grinding prevents spices from heating up during grinding and causing the essential oils to volatilise and heat-sensitive fats to melt. in the worst case, this can lead to the grinding elements clogging up and the mill blocking. cryogenic grinding therefore optimises both the product properties and the process management. it is possible with cryogenic grinding to.
