How to Reduce Peanut Kernel Breakage with a Peanut Shelling Machine?

Peanut kernel breakage is an important concern when choosing a peanut shelling machine. Excessive breakage can reduce the quality and selling value of peanut kernels. A suitable machine, correct screen selection, and proper operating conditions can help achieve efficient shelling while reducing kernel damage.

Choose the Right Screen Size

One of the most important factors affecting peanut kernel breakage is the screen size. Different peanut varieties have different kernel sizes, so the screen should be selected according to the actual width of the peanuts.

The combined peanut shelling and cleaning machine supports different screen mesh sizes, including 7, 8, 9, and 11 mm for certain models. Larger models can also be equipped with three or four screens, making it easier to process peanuts of different sizes and improve shelling results.

Keep Peanuts Properly Prepared

Before shelling, peanuts should be cleaned and maintained at a suitable moisture level. The recommended working humidity for this machine is 6.3%–12%. Excessive moisture or unsuitable material conditions can affect shelling performance and increase the risk of kernel damage.

The integrated cleaning system first removes dirt, stones, leaves, and other impurities. This helps protect the shelling equipment and provides cleaner material for the next processing stage.

Select the Correct Machine Capacity

Choosing a machine that matches your processing requirements is also important. The combined peanut shelling and cleaning machine is available in several models, with capacities ranging from 700–800 kg/h to 5,000–8,000 kg/h.

For example, the 6BHX-1500 is suitable for smaller-scale processing, while the 6BHX-20000 is designed for much higher output. Selecting an appropriate model helps maintain stable processing instead of forcing a machine to operate beyond its suitable capacity.

Use a Combined Shelling and Cleaning System

A combined machine integrates cleaning and shelling into one processing system. The cleaning section removes impurities before the peanuts enter the sheller, while the shelling section uses a closed screen box and fan to separate shells from kernels.

This design not only improves processing efficiency but also helps maintain cleaner peanut kernels. According to the product specifications, the different models have a shelling rate of ≥99%, breakage rate of ≤5%, and loss rate of ≤0.5% under the stated operating conditions.

Maintain the Peanut Shelling Machine Regularly

Regular cleaning and maintenance should not be overlooked. Dirt, stones, metal pieces, and other impurities should be removed before operation. Keeping the machine clean helps maintain stable performance and reduces the possibility of operating problems.

Choose a Peanut Shelling Machine for Your Needs

Reducing peanut kernel breakage requires more than simply choosing a high-capacity machine. Correct screen selection, suitable peanut moisture, proper machine capacity, effective pre-cleaning, and regular maintenance all contribute to better shelling performance.

For commercial peanut processing, a combined peanut shelling and cleaning machine can provide an efficient solution by completing cleaning and shelling in one system while maintaining a low stated breakage rate.
