Powerful Cryogenic Grinders for Sample
The Freezer/Mill® is a programmable cryogenic grinder specifically designed for milling and grinding of tough or temperature sensitive samples. Samples are placed in sealed cryogenic grinding vials then immersed in liquid The cryogenic grinding system consists of two main units, namely precooling unit and grinding unit. Materials. For the present study, cumin seed was obtained from the local market during February–March, 1995. The initial average moisture content of the seed was found to be 9.53% d.b.

Cryomill the perfect mill for cryogenic grinding RETSCH
The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughlyWe investigated the influence of cryogenic grinding on the quality of rapeseed cake. Rapeseed cake is a good source of valuable proteins (30%) and oil (14%), with a balanced fatty acid composition and a fair amount of sterols, which may reduce the risk of cardiovascular diseases.
