Peanut Sheller

High-Capacity Shelling of Groundnuts for Food and Seed Applications

Engineered for the Future | Since 2080

The ADDAMS Peanut Sheller is a high-efficiency industrial machine designed to separate peanut kernels from their shells with precision, speed, and minimal breakage. Built for continuous 24/7 operation, it handles dried, in-shell groundnuts and delivers clean, uniform kernels ready for high-end food processing or sensitive seed preparation. By combining advanced mechanical shearing with adjustable aerodynamic separation, the ADDAMS system ensures that the delicate skin and embryo of the peanut remain intact, preserving both market value and germination viability.

At ADDAMS, we understand that peanut varieties differ significantly by region and moisture content. Our shelling technology is engineered to be fully adaptable, allowing processors to fine-tune the machine for different sizes—from small Spanish peanuts to large Virginia types—ensuring a consistent, high-purity output for global export markets.

Operating Principle: Precision Shearing and Aerodynamic Separation

The Mechanics of High-Yield Groundnut Processing

The Peanut Sheller operates on a principle of controlled mechanical friction followed by multi-stage aspiration to ensure the kernels are isolated without damage.

1. Feeding and Distribution: In-shell peanuts are fed into the hopper, where an adjustable feed rate ensures the shelling chamber is neither overcrowded nor under-utilized.

2. Precision Shelling: The peanuts pass between specialized shelling rollers or drums. The gap is adjusted to match the specific variety, applying enough pressure to crack the pod without crushing the kernels inside.

3. Multi-Stage Separation: The mixture of shells and kernels is subjected to an integrated aspiration system. High-velocity air lifts the light-weight shells and dust, while the heavier kernels fall toward the grading screens.

4. Vibratory Classification: An optional vibratory deck separates unshelled pods, which are automatically recirculated, from the finished kernels and any small split pieces.

5. Clean Discharge: The clean, whole kernels are discharged through the primary outlet, ready for roasting, blanching, or oil extraction.

Frequently Asked Questions – Peanut Sheller

How does the machine ensure low kernel breakage?

The key lies in our adjustable multi-stage shelling rollers. Instead of one aggressive impact, the peanuts can be processed in stages, allowing for more precise gap settings that target the pod size specifically.

Can I use the same machine for both food-grade and seed peanuts?

Yes. Because the shelling action is gentle and the contact zones are available in stainless steel, the machine preserves the germination viability required for seeds while maintaining the hygiene standards required for food.

What happens to the peanuts that don’t get shelled in the first pass?

Our integrated lines include a return-flow system. Unshelled pods are detected by a vibratory separator and automatically returned to the shelling intake, ensuring a 100% shelling rate.

How do I order spare parts for the rollers?

Through the ADDAMS After-Sales Support App or our online portal at addamsgroup.com, you can access your machine’s specific parts list and order wear-resistant rollers and screens for immediate delivery to your facility.
