Description

A disc-type peanut shelling machine

technical field

The invention relates to the technical field of shelling machines, in particular to a disc-type peanut shelling machine.

Background technique

Existing shelling machines mainly include drum type peanut shelling machine, scraper type peanut shelling machine, air explosion type peanut shelling machine and the like.

Among them, the working principle of the drum-type peanut sheller is the blow method. Peanuts are impacted and sheared in the rotating drum to break the shell and achieve the purpose of shelling. Peanut pods are repeatedly struck between the rotating drum and the fixed concave plate sieve, and the peanut shell is hit by the rod and the friction between the shell and the concave plate sieve, so that the peanut shell is broken and the shell is separated. The utility model has the advantage of simple structure, but the breaking rate of peanut pods is not high and the damage rate of peanut kernels is relatively high.

The working principle of the scraper type peanut sheller is extrusion shelling. When the equipment is working, the peanuts enter the shelling chamber from the feed hopper, and are repeatedly hit and collided by the high-speed rotating shaft part-the scraper, as well as the friction, grinding, shearing, Under the action of extrusion, the peanut shells are continuously broken. The peanut shells are broken by extrusion and separated from the peanut kernels to achieve the effect of shelling. The main factor affecting the cleaning rate and breakage rate of this type of sheller is whether the gap between the two rollers can make the pods be clamped and smoothly enter the gap to achieve the purpose of extrusion. Therefore, the grading of peanut pods has a great influence on the shelling effect.

The working principle of the air explosion peanut sheller is the air explosion method, also known as the pressure expansion method. The method is to use the air permeability of the peanut shell, put it into a sealed container, and fill the peanut pod with a certain pressure of gas. The high-pressure gas is released instantly, and the air pressure balance of the peanut pods is broken. Under the impact of the high-pressure gas inside the Yingguo, the shell explodes from the inside out to complete the shelling process. This principle depends on the gas pressure to remove the shell, so it is greatly affected by the air pressure and the maintenance time of the air pressure. The shelling efficiency of this shelling method is very low. After the gas explosion shelling, follow-up processing is required.
