A disc rotor with an impact pin is attached along its vertical axis inside a cast iron casing installed on top of the steel frame, which is spun at high speed by a belt. Grains are fed into the center of the rotor through a feeder at the top, and they are quickly scattered toward the outside by centrifugal force, where they are struck by the pin. The grains are also polished by the effect of them hitting the wall of the casing. The flattened grains then fall from the wall. There is also an aspirator, which blows air onto the grains to separate and remove any impurities they contain, such as the lighter epidermis and saccharide, by blowing them away.
The high-speed aspirator relies on the force of impact due to the centrifugal force to kill insect larvae attached to the surface of grains, while simultaneously polishing their surface, and separating and removing impurities and contaminants generated by the polishing process by blowing air onto the grains. This machine has the functions of both the sculler machine and aspirator of a conventional grain separator, and it can also clean and separate contaminants from grains even more than is possible by cleaning them only with water in a washer. It is extremely compact despite its capabilities, making it a revolutionary separator.
