A multifunctional rice mill with upward suction

Abstract

The invention relates to the field of grain machine devices, in particular to an upper-air-drafting multifunctional rice husking machine. The upper-air-drafting multifunctional rice husking machine comprises a rice husking machine body and a motor used for driving the rice husking machine, the rice husking machine body comprises a feeding opening, a husking and whitening chamber, a main shaft and a white rice discharging opening, the main shaft is horizontally arranged in the husking and whitening chamber, a main emery roll used for rice husking is fixed to the main shaft, and an upper air drafting opening used for discharging bran is formed in the top of the rice husking machine body; a husking and whitening chamber air inlet is formed in the lateral face of the husking and whitening chamber and is communicated with the upper air drafting opening through the husking and whitening chamber, and a broken rice discharging opening is formed in the bottom of the husking and whitening chamber. The rice bran is discharged through the upper-air-drafting multifunctional rice husking machine in the upper-air-drafting mode, so that the defect that rice grains are accumulated at the lower portion of a traditional rice husking machine is overcome; a grid tray bran screening and separating device is additionally arranged so that secondary screening can be carried out on broken rice; a tail segment refined husking roller is additionally arranged on the main shaft so that a client can conduct flexible selection according to grains needing to be processed in the processing process.

Description

technical field [0001] The invention relates to the field of grain machine equipment, in particular to an upward-suction multifunctional rice mill. Background technique [0002] The traditional bran discharge method of the horizontal rice mill mostly adopts the bran discharge method of suction under negative pressure. The biggest defect of this method is that the rice grains are affected by their own gravity and the suction force under the negative pressure. During the flow of the rice grains in the milling chamber, a large amount of them will be stored in the lower part of the milling chamber, resulting in a large flow resistance. Uneven internal pressure, poor bran discharge, uneven whitening, high energy consumption and other comprehensive problems. The traditional horizontal rice mill mainly has the following disadvantages: [0003] 1. The roller of the horizontal emery roller rice mill is generally sintered with corundum and the internal cast iron core. From the poin...

AI Technical Summary

Problems solved by technology

But the reality is that the particle size and particle shape of various grains are different, and this traditional structure is difficult to meet the processing requirements of various grains

[0004] 2. During the whitening process of brown rice in the milling room, bran powder and broken rice will be produced

Because the value of broken rice is far from the value of rice bran, it will cause great waste

[0005] 3. The outlet of the traditional horizontal rice mill mostly adopts a simple pressure door discharge device

As a result, the quality of the white rice is not good; or it flows into the pipeline and causes the accumulation of bran powder, which is difficult to clean up; or it flows into the subsequent rice machine, which increases the burden on the subsequent rice machine
