Abstract
In an insulated mixing and cooling chamber having a feed auger to deliver cooled particles to a grinder and an intromitter auger rotatable around the feed auger to mix the particles within the chamber, independent variable speed, reversible motors operate the intromitter and feed augers, whereby the relative rotation of the augers may be precisely adjusted even while the mixing apparatus and associated grinding apparatus are operating. Electronic and or pneumatic control of cryogenic liquid inflow, as well as electronic control of the auger drive motors, may be used to optimize cooling and mixing conditions.
