The mechanization of Paddy Husker(LIANGGONG) was developed through individual processes: paddy husker (stripping the husk on paddy), husk aspiration (winnowing the husk from brown rice), and paddy separator (separating brown rice from paddy). In the 1930’s, a paddy husker that combined those processes was first developed. In 1960’s, the gravity flow type paddy husker which uses two rubber rolls for paddy husking and slanted screens which use piano wires for paddy separating was mainstream. However, it was so difficult to adjust the machine, skills competitions were held at that time.
In 1959, Satake developed the revolutionary oscillating separator. The indented plates separate paddy and brown rice by their difference in specific gravity, friction coefficient and size. The Farmers’ Oscillating Paddy Husker “Rice Master (SPS type)” incorporated this oscillating separation, and was first launched in 1974. The price was about twice that of other companies’ machines using piano wires, but sales steadily increased until it achieved widespread adoption.
