Technical study of peanut shelling machine

In the study of shelling technology, in addition to the principle and equipment, people still studied the process to improve the shelling rate of seed and shelling quality.
Grading process of peanut shelling machine: Since the particle size of material is large, it must be graded by size first before shelling to improve the shelling rate and reduce the damage rate.

Peanut Shelling Machine
Moisture content: The moisture content of peanut pods has great influence on the shelling effect. If the moisture content is higher, the toughness of the shell would increase; if the moisture content is lower, then the fines content of nut is high. Thus, the most appropriate moisture content of peanut pods should be kept to ensure the difference of the maximum elastic deformation and plastic deformation of shells and kernels, that is, the moisture content of shells should be lower enough to make it have the greatest brittleness that can be fully broken in the shelling process. At the same time, the plasticity of the kernel should be kept. The fines content of kernels can't be too large under the action of external force due to the low moisture content, which can reduce the breakage of kernels.
