Abstract: A pulverizer used to pulverize tea leaves, grain such as sesame and wheat, and minerals such as ceramics and rocks. A pair of upper and lower mortars provided for the pulverizer are rotated relatively to pulverize material between the pulverizing surface provided on the top surface of the lower mortar and the pulverizing surface provided on the bottom surface of the upper mortar. The pulverizing surface of the lower mortar is formed in a concave conical shape and the pulverizing surface of the upper mortar is formed in a conical shape matching the concave conical shape. Accordingly, when pulverization is performed between the pulverizing surfaces of the upper and lower mortars, the material is raised along the pulverizing surface of the lower mortar toward its outer peripheral section and slips down along the pulverizing surface, returning toward its central section. This up-and-down movement is repeated. The material can therefore be retained for an extended period of time between the pulverizing surfaces.

Abstract: Grain is fed from a hopper to a horizontally oriented adjustable speed steam heated auger driven by a variable speed drive. The auger is long enough (approximately twenty inches) that temperature controlled steam fed to a plurality of inlets along the auger as related to the rate of grain movement through the auger heats the grain therein to approximately three hundred degrees fahrenheit. Then it is dropped through a grain outlet opening into a high velocity cold air stream temperature shocking the hot grain causing a sudden contraction of grain outer layers causing them to crack and loosen from the grain core. The grain is then fed through tubes to space between a rotatable internally rubber (or soft plastic) sheet layer sheathed inner surface outer mill member fitted to and rotatable about a truncated cone member having outer surface metal channel members angled approximately forty five degrees adjacent at the top and diverging at the bottom.

Abstract: A series of screens for use with a size reduction machine have a tapered apertured wall formed into a frusto-conial shape, with an open wide end and a narrow closed end. All screens of a particular series have a cylindrical section, the same interior depth, outside diameter and angle of the tapered wall. Despite variations in the material wall thickness, screens of the same series are interchangeable on a size reduction machine and the gap can remain constant without any adjustment to the impeller. Further, a size reduction machine has means external to the machine providing for infinite adjustments to the gap. With previous machines, each time that a screen of a different thickness was used, it was necessary to make an adjustment to the gap in order to maintain the same gap. Further, when an adjustment to the gap is required, that is accomplished by removing the screen and impeller from the machine and inserting spacers onto the shaft.
