Several common peanut shellers

Peanut shelling methods are mainly divided into non-mechanical shelling and mechanical shelling. At present, mechanical peanut shelling equipment is mainly used in the market. According to the different principles and structural forms of shelling, the main forms of common peanut shellers can be divided into two types: hitting and kneading type and grinding disc type. Among them, the hitting and kneading type is the most widely used. The peanut kernels enter the shelling bin from the feeding hopper. Under the combined action of rolling and concave screen in the shelling bin, the peanut shells are squeezed and kneaded to realize shelling. The sieve is discharged to the vibrating screen. During the falling process, the husk is blown out by the fan between the concave plate screen and the vibrating screen. The peanut kernels and the uncleaned peanut nuts are separated under the action of the vibrating screen and the cleaning fan, and the seeds are separated. The kernels enter the material box from the discharge port for collection, and the unhulled pods enter the dehulling device through the pneumatic conveying pipeline to complete the whole shelling process.

In this shelling equipment, the shelling bin is the key component, which has an important impact on the quality of the shelling machine. The hulling bin consists of a hulling and rolling screen and a concave plate screen. According to the different structural forms of the hulling and rolling, it can be divided into two types: open shelling and rolling and closed shelling and rolling. The difference between the two in operation principle and operation quality is as follows: when the combination of the open shelling roller and the concave screen is used to shell the peanuts, the peanuts enter the shelling bin and are first hit by the rotating rod during the falling process. Afterwards, the Yingguo falls between the rolling concave screen. Under the rotational drive of the rolling rod and the blocking action of the concave screen, the external force is applied between the pod and the rotating rod concave screen, and between the pod and the Yingguo. Kneading and squeezing, so that the pod husk is broken, and the seed kernel is prolapsed under the action of external force. The gap is discharged from the shelling bin. Under this structure, each rod (board) has a significant impact on the peanuts in the shelling bin, and the breakage rate is relatively high, but its structural characteristics make the shelling bin larger space, and the requirement for the uniformity of pod feeding is low. It can realize the shelling of peanut pods with a large feeding rate, and the productivity is relatively high. It is suitable for high-efficiency shelling of oil and edible peanuts. Compared with the above structure, the closed shelling rolling concave screen structure has a better impact on the pods. Weak, when the pods fall from the hopper to the shelling bin, driven by the closed drum, the shelling is mainly achieved under the rubbing and squeezing action of the shelling drum, and the damage rate is relatively small, but its structural characteristics make shelling easier. The space in the silo is relatively small. In actual production, the uniformity of the feeding of the shelling equipment is relatively high. The feeding rate is fast and easy to cause blockage, which affects the normal operation. It can be used for low-loss shelling of seed peanuts.

The structure of the punching and kneading peanut shelling bin is also quite different from the peanut shelling equipment produced by different manufacturers. In the process of shelling, the braided screen has a large blocking effect on peanuts, and the removal rate is high. Relatively small.
