Abstract: A pepper seed polishing machine consists of a frame made from welded angle iron bars, a polishing mechanism which is a concave made from iron sieve having holes with diameter of 1.5-2 millimeters, and an agitator set. The agitator set consists of three backward curve vane blades welded onto a rotating shaft and is driven by a two-horsepower electric motor via a two V belt-pulley set. Black pepper seed is loaded into a hopper located on top of the machine. After polishing process, the polished seed is unloaded from the machine, while dust and rubbish can be collected separately. Polishing or rubbing off the outer skin of pepper seed resulted from rubbing action between seed to metal and seed to seed. The revolution of the rotor can be changed by changing pulleys' diameter. This results in changing of time required for each cycle of polishing process and polishing capacity as well. After polishing, the pepper seed has much more favorably odor than those polished by the conventional method.

Abstract: A discoid element (7, 8) for a helical screw or worm arrangement comprising, on each side, identical shallow depressions (20); each depression having an open end (21) adjacent the periphery and a closed end (22) adjacent a central bore (23). The depressions (20) in one side of the discoid element are staggered with respect to those of the other side. The discoid element may also contain radial ribs (24, 25, 26, 27) constituting the sidewalls of the shallow depressions. The discoid elements may suitably be used in apparatus for dehusking grain.

Abstract: Disclosed is the improvements in whitening apparatus for producing strongly glossy white rice without using any gloss additive. The improved apparatus wherein: friction between half-finished white rice grains which have been moistened while being supplied to a whitening chamber of the apparatus is caused by the rotation of a whitening roll axially disposed in a perforated bran-removing and whitening cylinder, said roll and said cylinder are defining therebetween said whitening chamber, whereby the surfaces of grains are fully cleaned of bran which is constantly discharged through the perforated wall of said cylinder, thereby enabling to expose hard portions of white rice grains devoid of bran. The ratio between the length and diameter of said cylinder experimentally substantiated for best results may be between 2:1 to 20:1.

The drum and the paddles both rotate in the same direction at prescribed velocities.

Abstract: A method is characterized by causing a container with grain loaded therein to perform two rotary motions, that is a rotary motion about its own axis and a rotary motion about an axis of rotation extending in parallel with and in the same plane as its own axis, with subsequent positive removal of seed covers. The method enables the separation of seed cover from endosperm of grain of various cereal crops without destructing endosperm. An apparatus for carrying out this method is provided with at least two containers mounted in a hollow casing in parallel relative to each other for rotation about their common axes and interconnected for combined rotation about a common axis of rotation extending in parallel with their own axes. The apparatus has means for charging grain communicated with the containers, as well as collectors for seed covers and endosperm of grain communicated with the containers.
