Impurity removing device for rice processing

[0013] The present invention will be further described below in conjunction with embodiments and with reference to the accompanying drawings. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the figure, and the words "inner" and "outer" "Respectively refers to the direction toward or away from the geometric center of a particular component.

[0014] Such as figure 1 The impurity removal device for rice processing according to the present invention includes a shell 1 and a feeding funnel 2; a feeding funnel 2 is provided above the shell 1, and a flat vibrating screen is provided inside the shell 1 below the feeding funnel 2 3. The aperture of the flat vibrating screen 3 is larger than the diameter of the rice by 0.5-1 mm, a blower 4 is provided on the side wall of the housing 1 above the flat vibrating screen 3, and an impurity collection box is provided on the right side of the flat vibrating screen 3 5. The opening of the impurity collection box 5 faces the blowing pipe 4, and an inclined vibrating screen 6 is provided directly below the flat vibrating screen 3. The diameter of the inclined vibrating screen 6 is smaller than the diameter of the rice by 0.5-1 mm. The vibrating screen 6 is provided with a cleaning chamber 7 on the right side. The opening of the cleaning chamber 7 is connected to the lower end of the inclined vibrating screen 6. A motor 8 is provided above the cleaning chamber 7 and the motor 8 drives the cleaning chamber 7 The stirring shaft 9 rotates, and a water inlet pipe 10 and a water outlet pipe 11 are connected to one side of the cleaning chamber 7. The water inlet pipe 10 is located above the water outlet pipe 11, and the bottom of the cleaning chamber 7 is provided with a rice outlet port 12.

[0015] The working process of the present invention: After the rice is poured in through the feeding funnel, the blower blows the straw, rice bran, etc., which are lighter in weight, into the impurity collection box, and then falls on the flat vibrating screen, which has a larger aperture than the rice 1-2mm. Therefore, the rice passes through and leaves with a diameter larger than that of the rice. The rice falls on the oblique vibrating screen. The aperture of the oblique vibrating screen is smaller than that of the rice. Therefore, impurities with a small diameter pass through and the rice is left behind. The opening of the cleaning chamber falls into the cleaning chamber for cleaning, the stirring shaft stirs and cleans the impurities on the surface of the rice, and then the water is discharged, and the rice is poured out through the rice outlet.

[0016] As an embodiment of the present invention, a baffle 13 is further provided at the opening of the cleaning chamber 7. The function of the baffle is to guide the rice on the inclined vibrating screen into the cleaning room.

[0017] As an embodiment of the present invention, the bottom of the cleaning chamber 7 is in the shape of a funnel cone. The bottom of the cleaning chamber can facilitate the pouring of rice smoothly.

[0018] As an embodiment of the present invention, a filter screen is added to the side wall of the cleaning chamber 7 at the water outlet 11, and the filter screen completely covers the water outlet. The filter is to prevent part of the rice from flowing out of the water outlet.

[0019] The invention provides a rice processing impurity removal device, which can not only remove the straw, rice bran and other impurities lighter than rice in the rice, but also remove impurities such as stones larger in diameter and smaller than rice in diameter, and finally remove stickiness. The rice bran, rice, etc. attached to the surface of the rice can basically remove impurities, improve the overall quality of the rice, and increase the taste of the rice.

[0020] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any other form. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope of protection claimed by the present invention. .
