Description

A roller type peanut shelling machine

Technical field

The utility model relates to the technical field of peanut shelling, specifically a drum-type peanut shelling machine.

Background technique

The shelling machine is the core machinery in the peanut shelling processing equipment series. It is also the key to determining the efficiency of peanut shelling and the degree of kernel damage and loss. China's peanut production accounts for about 40% of the world's and ranks first, but its technical level in peanut harvesting and shelling processing is far lower than that of the United States, whose output is less than one-seventh of China's. The low efficiency and quality of peanut shelling has largely restricted the development of my country's export of peanuts and products and the development of the food processing industry. Peanut seed shelling is an important part of peanut seed preparation before sowing. The quality of peanut seeds after shelling directly affects emergence, growth and yield. At present, peanut seed shelling is mostly based on the appearance characteristics of the peanut pod, using principles such as rubbing, squeezing, and impact, and using shelling components (drum type, flat type, etc.) and shelling screens (punch screen, grid screen, etc.) The interaction between the peanut pods causes the peanut pods to crack and break to complete the shelling. The peanut shelling machines all have problems such as low removal rate, high peanut kernel damage rate, and poor adaptability to peanut varieties to a certain extent. In response to the above problems, the present invention designs a shelling mechanism with uniform feeding, a rotatable gravure screen and anti-clogging function, in order to achieve high-efficiency and low-damage shelling of peanuts.

While improving the efficiency of peanut shelling, we also need to pay attention to the peanut shelling effect and the quality of the peanut kernels after shelling. Existing peanut shelling machines use a centralized crushing method. The peanuts are squeezed out of order in the drum to achieve shelling. Usually, the method of increasing the rotation speed is used to improve production efficiency. This causes the quality of the peanut kernels to deteriorate due to excessive extrusion after shelling; Especially in terms of peanut seed shelling, the quality requirements of the shelled peanut kernels are relatively high. The existing peanut seed shelling is mostly manual shelling, which has problems such as low efficiency and high labor intensity. Therefore, there is an urgent need for a uniform feeding and Peanut shelling machine with high shelling efficiency and minimal damage to peanut kernels.
