As an important agricultural machinery and equipment, the working efficiency and shelling quality of peanut sheller machine are directly related to farmers’ economic benefits. In the process of peanut shelling, air volume control is a key link. Reasonable air volume adjustment can not only improve the shelling efficiency, but also reduce the breakage rate of peanut kernels and improve the quality of finished products.
First of all, the main function of air volume control is to separate the shelled peanuts from the shells. By adjusting the wind power of the fan, the lighter peanut shells can be effectively blown away, while the heavier peanut kernels will fall, thus realizing separation. If the air volume is too small, the peanut shells may not be completely blown out, resulting in incomplete separation; If the air volume is too large, the peanuts may be blown away together, resulting in a waste of resources. Therefore, accurate control of air volume is the key to ensure the normal operation of equipment and improve separation efficiency.
Secondly, different varieties of peanuts have different requirements for air volume. For example, due to the differences in weight and shape between small peanuts and large peanuts, it is necessary to adjust different air volume to achieve the best separation effect.
| Peanut Type | Average Kernel Weight (g) | Shell Thickness | Recommended Air Velocity (m/s) |
|---|---|---|---|
| Spanish (small) | 0.4–0.6 | Thin | 8–10 |
| Virginia (large) | 0.8–1.2 | Thick | 12–15 |
| Runner (medium) | 0.6–0.8 | Medium | 10–12 |
Practical tip: Before large-scale operation, run a 5–10 kg sample batch. Gradually increase fan speed from minimum until shells are cleanly removed but no kernels are observed in the waste stream. Document this baseline setting for each variety.
Besides, environmental factors will also affect air volume control. For example, in a humid environment, peanut shells may become heavier due to moisture absorption, so it is necessary to increase the air volume appropriately at this time; In dry environment, it is necessary to reduce the wind power to avoid excessive blowing. Therefore, the operator needs to flexibly adjust the equipment parameters according to the actual environmental conditions.
In order to achieve accurate air volume control, modern peanut sheller is usually equipped with adjustable fan or intelligent control system. These technical means make the operation easier and improve the automation level and work efficiency of the equipment.
In a word, the air volume control of peanut sheller machine is an important factor affecting the shelling effect. By adjusting the air volume reasonably, the shelling efficiency can be effectively improved, the loss can be reduced, and the product quality can be ensured. In practice, users need to flexibly adjust the equipment according to peanut varieties, environmental conditions and other factors to achieve the best use effect.
