Dispersers provide the mechanical energy to breakdown agglomerated particles to smaller aggregates. There are two classes of dispersers to grind material. The first group uses a high shear disperser blade rotating at a high speed. The second class are bead mills that use grinding media. A mechanical force moves the media at a rapid speed ...

Hello. I recently just purchased the VitaMix dry container for milling grain. I freeze the grain so the temperature doesn't get too high, but even so to get a fine/finer grind I have to mill for about 1 min 20 sec. The flour seems quite warm. I have taken the temperature of the flour immediately after grinding, but I have been unable to find at which temperature the enzymes
