Abstract

A rice washing apparatus which can wash rice in a short time with a high degree of efficiency, and which can prevent occurrence of fragmentation of the rice, is composed of a rice washing tank formed of a cylindrical body, having a lower part in an inverted conical shape, and formed in its lower end with a rice discharge port, a water discharge pipe connected to a side of the lower part of the rice washing tank, a hollow valve rod adapted to be moved up and down in the rice washing tank, and provided in the lower part thereof with a rice discharge valve for opening and closing the rice discharge port, a hollow rotary shaft through which the valve rod is extended, and an agitating member 10 mounted to the rotary shaft. Water is fed into the valve rod through the upper part of the latter and flows down therein so as to suck air thereinto through air intake ports formed in the rotary shaft and the valve rod, and accordingly, the air and the water are mixed so as to produce bubbles which are then discharged into the lower part of the rice washing tank. Thus, the rice is washed by the water and the bubbles so as to enhance the effect of polishing of the rice, and to allow impurities such as rice bran to overflow from the rice washing tank with the use of the quality of the floatation of the impurities.
