Secondary fine-screening device for mixed materials of rice blending system

Abstract

The invention discloses a secondary fine-screening device for mixed materials of a rice blending system. According to the secondary fine-screening device, a three-way valve is additionally installed at the bottom of a blended rice cabin, and a flow pipe is connected to a discharging opening of the three-way valve to enable materials to flow back to a feeding opening of a grading screen lifting machine; parts of the materials flow back to a white rice grader in the manner that the opening degree of the three-way valve is adjusted for secondary screening, and large broken rice and complete rice in blended rice are separated out again through current fine screening; the separated-out complete rice enters a complete rice cabin 1 of a rice blending cabin; and the separated-out large broken rice enters a large broken rice cabin 2 of the rice blending cabin, and only a quite small amount of large broken rice returns to the blended rice cabin 3 of the rice blending cabin again. By means of the secondary fine-screening device, the material level of the blended rice cabin can be lowered in time, the grain shape sense of finished products can be stabilized, manual physical labor is not required for re-grading the materials of the blended rice cabin in the stopping state, the mixed materials can also be continuously screened to be blended into the rice blending system during starting normal production, continuous conducting of production is guaranteed, and influences, caused by stopping processing generated when the blended rice is surplus, on the production yield are prevented.

Description

technical field [0001] The invention relates to a device capable of performing secondary refinement on non-consumable mixed materials aiming at the existing rice blending technology. Background technique [0002] At present, most rice processing enterprises use rice blending technology. According to the grade requirements of different rice blending schemes, white rice is sorted into whole rice, large broken rice, mixed rice, medium broken rice, and small broken rice. Different types of broken rice are prepared to achieve the purpose of improving appearance, meeting quality requirements, balancing nutrition, and improving economic benefits. When blending rice, different types of rice should be mixed according to specific ratios. However, due to the high output of mixed materials in the rice blending cabin when the raw grain is poor, it is impossible to consume more mixed rice when producing medium and high-end products, and it is very easy to cause a surplus of mixed rice.

Problems solved by technology

In order to overcome the shortage of existing rice blending machinery and bin capacity, the present invention provides a secondary selection device for the mixed material for the existing rice blending machine, the purpose is to synchronously select and re-separate the mixed material through partial reflux in the mixed rice bin Produce the broken and whole rice in the mixed rice that cannot be consumed, reduce the amount of rice in the mixed rice warehouse, and at the same time improve the production efficiency of the entire system, effectively reduce costs and improve benefits
