Embodiment 2
[0033] Embodiment two: on the basis of embodiment one, its difference is, rice dedusting process, comprises the following steps:
[0034] A, send rice: use the belt conveyor that the rotating speed is 140r / min to send the finished rice into the upper cylinder 10;
[0035] B. Loose rice: When the rice enters the upper cylinder 10, it needs to pass through the rice dispersing plate 2, and the rice enters the rice inlet hole. The rice will be in contact with the bar plate 3 with 20 grids, and the bar plate 3 will hold the rice. Divided into multiple sub-flows, the sub-flows increase the contact area of the rice with the air, and the hindrance of the bar plate 3 will increase the distance between the rice grains when they fall;
[0036] C. Water spraying and dedusting: After the rice has passed through the step of loosening rice, start the water spray pipe 5, the flow rate of water is 0.7L / s, the water spray pipe 5 sprays water into the atomizing nozzle, and the atomizing nozzle...
Embodiment 3
[0038] Embodiment three: on the basis of embodiment one, its difference is, rice dedusting process, comprises the following steps:
[0039] A. Sending rice: use the belt conveyor with a rotating speed of 85r / min to send the finished rice into the upper cylinder 10;
[0040] B. Loose rice: When the rice enters the upper cylinder 10, it needs to pass through the rice-loosening disc 2, and the rice enters the rice inlet hole. The rice will be in contact with the stopper disc 3 with 16 grids, and the stopper disc 3 will hold the rice Divided into multiple sub-flows, the sub-flows increase the contact area of the rice with the air, and the hindrance of the bar plate 3 will increase the distance between the rice grains when they fall;
[0041] C. Water spraying and dedusting: after the rice has gone through the step of loosening rice, start the water spray pipe 5, the flow rate of water is 0.5L / s, the water spray pipe 5 sprays water into the atomizing nozzle, and the atomizing noz...

Abstract
The invention discloses a rice dust removing device. The rice dust removing device comprises an upper cylinder and a lower cylinder; the upper cylinder is fixedly connected to the top of the lower cylinder; a rice scattering disc is arranged on the upper cylinder; a rice inlet hole is formed in the rice scattering disc; a mesh-shaped stop rod disc is fixedly connected into the rice inlet hole; water spraying pipes are peripherally distributed on the upper cylinder, and are connected with atomizing nozzles towards the inner side of the upper cylinder; air inlet holes are uniformly distributed in the axial direction of the lower cylinder; a water sucking cylinder is fixedly connected into the lower cylinder; spiral blades are arranged on the outer side wall of the water sucking cylinder; water sucking holes are uniformly distributed in the axial direction of the water sucking cylinder; and the water sucking cylinder is filled with water sucking materials. The invention further discloses a rice dust removing process; and the rice dust removing process comprises the steps of: (A) rice feeding; (B) rice scattering; (C) dust removal through water spraying; and (D) water and dust suction. The device directly uses atomized water for being matched with the water sucking cylinder to remove dust on the surface of rice; water can cool the rice, and can remove the dust, so that the dust removing effect is guaranteed, and the rice particle quality is guaranteed; and meanwhile, the process steps are simplified, so that the dust removing efficiency is improved.
Description
technical field [0001] The invention relates to a dust removal device and a dust removal process, in particular to a rice dust removal device and a rice dust removal processing technology. Background technique [0002] Rice dedusting is a step that needs to be carried out after finishing the rice. Generally, the common rice dedusting device is a centrifugal dust collector, which consists of an inner cylinder, an outer cylinder, a conical cylinder, an air inlet, and an ash discharge port. The inner and outer cylinders and the ash discharge port are located on the same axis; the inner cylinder is evenly distributed with dust discharge holes that rice grains cannot pass through. Spiral rotating at high speed. During the rotation, the dust particles are thrown to the inner wall of the outer cylinder under the action of a large centrifugal force and collide with the wall surface, friction and the speed gradually decreases to zero, and then fall to the cone part along the cylinde...
