ピーナッツ殻むきユニット（清掃・選別システム付き）

The peanut shelling unit integrates the cleaning and shelling systems into a single unit, forming a complete processing solution that includes peanut cleaning, shelling, and separation functions. It boasts a cleaning rate of≥99%, a shelling rate of≥99%, a loss rate of≤0.5%, and a breakage rate of≤5%.

It firstly removes heavy and light impurities from the peanuts, then performs multi-stage shelling. The peanut moisture content must be below 10% to ensure a high shelling rate and low breakage rate. It is particularly used in peanut-producing areas (hilly, mountainous, and sandy soil regions).

Significant advantages of the peanut shelling unit

1. Our peanut shelling unit consists of two parts: an impurity removal system and a peanut shelling system. This structure ensures the cleanliness of the raw materials before shelling, improving the final quality.
2. This peanut shelling processing machine features a three-roller shelling design that shells the peanut layer by layer. The adjustable gap between the rollers and the concave grid ensures a shelling rate of ≥99% and a breakage rate of ≤5%.
3. The shelling system is equipped with multi-layer grading screens to separate peanut kernels and shells, improving overall efficiency.
4. Its cleaning and impurity-removal section is equipped with a vibrating screen and a large fan, which uses a powerful airflow system to remove peanut shells and minor impurities.
5. The shelling section is equipped with an automatic re-shelling system, which can automatically grade and re-shell incompletely shelled peanuts, significantly improving the shelling rate.

Structure and function of the groundnut shelling machine

Cleaning system structure

Components:

• モーター
• Feed hopper
• Sorting screen
• Crankshaft
• Vacuum fan
• Air conveying device

Functions:

1. Removing heavy impurities (stones, clods of earth)
2. Removing light impurities (dust, leaves, straw)
3. Protecting the shelling rollers
4. Improving peanut quality

Shelling system structure

Components:

• モーター
• Feed hopper
• Shelling rollers (I, II, III)
• Concave grille
• Grading and sorting screen
• Crankshaft
• Vacuum fan
• A Conveying device
• B Conveying device

Functions:

1. Utilizing the friction between the patterned rollers and the concave grille to shell peanuts
2. Separating the kernel from the shell
3. Automatically performing secondary shelling on unprocessed peanuts
4. Minimizing breakage

1. Feeding hole: Put the peanut there.
2. Destoner machine: Remove the stones and other impurities in the peanuts.
3. Conveyor: Transfer the peanuts to the shelling machine.
4. Discharge hole: Peanut seed outlet.
5. Sheller: Remove the husk of the peanut.

Working principle of the peanut shelling unit

Step 1: Impurity removal

Raw peanuts enter the feed hopper and then the sorting screen. Under the action of crankshaft vibration and airflow from the suction fan, the heavier impurities (stones, clods of soil) are discharged through the impurity outlet, while the lighter impurities (dust, leaves) are sucked out by the fan.

Finally, the clean peanuts enter the air conveying system and are transported to the shelling system.

Step 2: Three-stage shelling

Peanuts enter the shelling roller I → Primary shelling

Unshelled peanuts enter the roller II → Secondary shelling

Remaining peanuts enter the roller III → Tertiary shelling

Machine shelling principle: Shelling is achieved through repeated friction between the rollers and the concave grid.

Step 3: Grading and separation

After the mixture enters the grading screen, the outer shells are discharged by the fan, while the kernels are discharged from the outlet. Unshelled peanuts are separated and automatically returned for secondary shelling. This cycle can achieve a shell removal rate of up to 99%.

Applications of this machine

This peanut shelling processing line is frequently used in peanut-growing areas, particularly in hilly, mountainous, and sandy soil regions, for shelling peanuts to remove impurities and achieve effective shelling.

Furthermore, it is especially suitable for peanut-producing areas, seed processing plants, commercial factories, agricultural cooperatives, and export-oriented enterprises that require clean, uniform, and high-quality peanut kernels.

If you are looking for a reliable, scalable, and long-term peanut processing solution, then a peanut shelling unit is an ideal investment for improving efficiency, reducing losses, and enhancing market competitiveness. Contact us for the price list!
