QUALITY MANAGEMENT


Cold Grinding, Cryogenic Milling


Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

With the cryogenic method specifically particle fineness can be achieved while maintaining product quality. Cooling of heat sensitive materials with liquid nitrogen during the grinding process prevents their temperature from rising during the mechanical grinding. The usual heating due to the grinding process is prevented which eliminates material melting and sticking.


A grinding under liquid and gaseous nitrogen is available on the following plants:



Cryogenic Milling is suitable for the following substances

  • Tough and elastic materials
  • Products with a high oil or fat content, such as nutmeg, oilseed, spices, flavourings
  • Dust-explosive material, as nitrogen or carbon dioxide produces an inert atmosphere by oxygen displacement which safely prevents fires and explosions.


Fields of application for Cold Grinding

  • Ethylene vinyl acetate (EVA)
  • Food for preservation of vitamins and proteins
  • Spices such as pepper, ginger, cardamom or cloves, for preservation of scents and flavourings, aromas, flavors and essential oils
  • Plastics, rubber, thermoplastics, elastomers and waxes
  • Substances with a low softening point
