Efficient and energy-saving unprocessed grain peeling, degerming, polishing and screening multi-use machine

Abstract

The invention discloses an efficient and energy-saving unprocessed grain peeling, degerming, polishing and screening multi-use machine, and relates to unprocessed grain peeling, degerming, polishing and screening machinery. A lower opening of a feeding hopper is communicated with a peeling chamber, a main shaft is transversely arranged on peeling chamber end plates through bearings, and a belt wheel fixed at the outer end of the main shaft is connected with a motor power wheel through a belt; the main shaft is provided with a rotating roller arranged in a screen net; an air channel is arranged outside the peeling chamber, and the tail end of the air channel is connected with a draught fan; the rotating roller is of a polygonal structure, each edge of a polygon is provided with a spring blade, the spring blades are pressed and fixed by spiral conveying pressing plates, and the rotating roller and the spring blades are matched with the screen net to rub materials; spiral blades arranged on the spiral conveying pressing plates simultaneously push the materials forwards; a large-hole-diameter screen net is connected in front of the screen net; a discharging port is formed in front of the large-hole-diameter screen net; a gland and a regulation and control device thereof are arranged at the discharging port. The efficient and energy-saving unprocessed grain peeling, degerming, polishing and screening multi-use machine has the advantages of being little in power, high in yield and quality and low in breakage rate and production cost and has the significant economic and social benefits.

Description

technical field [0001] The present invention relates to machinery, further to grain processing machinery, especially peeling and polishing machines for corn and rice. Background technique [0002] Rice milling is a process of partially or completely peeling off the cortex on the surface of raw grains by physical (mechanical) or chemical methods. At present, countries in the world generally use physical methods to mill rice. The mechanical equipment used to remove the cortex of raw grains is called a rice mill (or a peeling crusher, which is used to peel corn, wheat, rice (brown rice), etc.). Since the cortex tissue of raw grains such as corn and wheat has a lot of crude fiber, direct consumption will hinder the normal digestion and absorption of the human body. It takes a long time, the rice yield is low, and the color is dark, the viscosity is poor, and the taste is not good. Therefore, it is often necessary to remove the cortex of the raw grain through the rice milling p...

AI Technical Summary

Problems solved by technology

To sum up, both of the above two methods belong to the hard processing method, and the gap between the roller and the screen cannot be adjusted, and the whitening efficiency is low. When the internal pressure does not meet the requirements, it can only be adjusted by the pressure rotor at the discharge port. Therefore, the pressure in the radial whitening chamber is not uniform, so the broken rate is high, and the fine powder produced after the raw grain is broken is directly sucked away by the fan through the screen, so the yield is low and the waste is serious

[0004] All in all, because the existing technical structure adopts the principle of rigid rubbing, the following defects generally exist: 1. The power is large, generally 15kW to 45kW is required, and the production capacity per kW is usually only 50-90 kg per hour; 2. The output Low, usually 500-3000 kg per hour; 3. High crushing rate, usually above 50-60%; and the crushed grain is usually used as feed, which increases the cost of the product

4. The surface is rough and the appearance finish is poor, which affects the sales of the product; especially the speed rice milling machine, it is often necessary to use it with a polishing machine; 5. The cost of consumables is high, and the consumables are iron rollers or sand rollers, and the cost is high

And the existence of these defects of rice milling machine in the prior art causes food waste, electric energy waste, low production capacity
