Background technology
Existing polished rice technology can be divided into two classes according to polished rice action principle difference: grind and cut pure white and wipe from pure white.Stone roller is cut the pure white technology and is claimed pressure pure white technology again, mainly relies on relative motion between roller and all kinds of Grinding structural unit to come the grain of rice ground to grind to cut, and removes rice husk and chaff layer, and certain pure white gap is arranged between roller and the Grinding structural unit.Claim speed pure white technology and wipe from the pure white technology, principle is to drive between the grain of rice and the grain of rice in the pure white chamber, produce relative motion between the grain of rice and the Grinding structural unit by roller motion, mutual friction is peeled off grain of rice rice husk and chaff layer, this wiping is ground from the grinding that does not rely on roller and is cut, but must carry out under certain speed and frictional force.
The principle of above-mentioned two kinds of polished rice technology is had nothing in common with each other, but the grinding device that adopts in its process all is rigid material: grind and cut type rice polisher roller diamond dust roller commonly used, Grinding structural unit is generally metal rice cutter; Rubbing and separation type rice polisher roller is generally iron roll, and rice huller screen is used the cylindrical metal rice huller screen always.When paddy or brown rice at a relatively high speed or big strength collide these rigidity when grinding devices, local pressure is crossed the higher position and is occurred the situation that plumule comes off and cracks rice easily.
In the actual process, stone roller is cut type rice polisher roller rotating speed and is crossed low or the pure white excesssive gap all can make the pure white deleterious, and rubbing and separation type rice polisher processing rotating speed is crossed the low effect that also can make frictional force not have pure white inadequately, but plumule comes off and broken rice rate if the raising rotating speed can increase again.Keep plumule rice preferably in order to produce plumule, also have the method for many rice polisher combination continuous productive processes or repeatedly circulation is processed.But this method not only working (machining) efficiency is low, the situation that processing repeatedly also causes a meter temperature rise, plumule to come off and crack rice easily.
