Air-jetting rice polisher capable of achieving air intake through axial surface

Abstract

The invention discloses a wind-jet rice mill with axial air intake, which comprises a rice mill body and a fan. The inner cavity of the rice mill body is divided into a whitening chamber and a feeding chamber. The inner cavity of the rice milling machine body is provided with a main shaft; one end of the main shaft and the end of the air spraying drum are connected with a suction bearing seat for air intake and fixed on the rice milling machine body; The fan is a negative pressure fan, and is connected with the drive wheel arranged at the other end of the main shaft for connecting the driving device. The present invention changes the traditional shaft-end air intake mode through the axial surface air intake, overcomes the limitation of the air intake volume by the radial size of the main shaft, and ensures a large air volume and insufficient ventilation in the whitening room; the negative pressure air jet is adopted to ensure whitening and drinking. The bran removal effect is good, and at the same time, the rice grains are subjected to uniform whitening pressure in the roller to avoid crushing and reduce waste; and the invention has a compact structure, takes up little space, is convenient to use and maintain, and is worthy of widespread promotion.

Description

technical field [0001] The invention relates to a paddy processing equipment, in particular to a wind-jet rice milling machine with axial air intake. Background technique [0002] The rice processing process is generally divided into cleaning, husking, rice milling, and finished product processing. The rice mill is one of the main equipment in the rice processing process. The working principle of the rice mill is to press the internal pressure of the thallium and the push of the mechanical force to make the rice squeezed in the whitening room, and after self-friction and mutual friction between the brown rice and the grinding wheel, the rice can be quickly removed. cortex. The air-jet rice milling machine sprays cold air into the whitening room during the rice milling process, so that the rice milling effect is improved. , good color, lower rice temperature, less bran powder and other outstanding advantages. Therefore, the wind-jet rice milling machine is popularized quic...

Problems solved by technology

[0003] The traditional structure of jet rice milling machine is as follows: Image 6 and Figure 7 As shown, it mainly includes the rice milling main body, bran suction device, feeding device, and air blowing device. This structure has the following disadvantages: First, the rice milling machine adopts the shaft end air intake method, and the air intake is affected by the radial size of the main shaft. Restricted, and the air inlet hole is too small, resulting in small air volume and insufficient ventilation in the whitening room, resulting in poor air spray effect, resulting in poor whitening and bran removal effects, and a lot of broken rice, requiring multiple bran removal; other Second, the blower blower is used to blow air to the whitening room, and the bran suction device also uses a fan to suck the bran, so a rice mill is equipped with at least two fans, resulting in a complex structure and a large space occupation , It is troublesome to use and maintain, and the rice mill consumes a lot of energy
