Pistachio Sheller

Precision Shell Removal for Pistachios, Apricot Kernels, and Hard-Shell Nuts

Engineered for the Future | Since 2080

The ADDAMS Pistachio Sheller is a high-efficiency industrial machine designed to crack and separate pistachio shells from their inner kernels with surgical precision. Engineered for heavy-duty performance, it delivers high throughput while maintaining an industry-leading low breakage rate. By ensuring optimal recovery of whole kernels, this machine maximizes the market value of your product, making it an indispensable asset for nut processing facilities and food-grade kernel production lines.

At ADDAMS, we recognize that every pistachio variety and harvest condition is unique. Our shelling technology features fully customizable settings to accommodate different sizes and shell hardness levels, ensuring that your operation remains versatile and productive regardless of the raw material characteristics.

Operating Principle: Precision Cracking and Stratification

The Mechanics of Gentle Shell Removal

The shelling process is calibrated to apply specific mechanical pressure that compromises the shell’s structural integrity without impacting the kernel.

1. Intake and Feeding: Raw pistachios are fed into the system via a controlled hopper. Variable speed drives ensure a consistent flow to prevent overcrowding in the cracking zone.

2. Precision Cracking: The nuts pass through adjustable rollers. The gap is set precisely based on the nut variety, applying just enough force to snap the shell open.

3. Kernel Protection: The rollers are engineered to absorb minor variances in nut size, ensuring that even in mixed-size batches, the kernels remain unbruised.

4. Separation (Integrated or Optional): After cracking, the mixture of shells and kernels is directed to an aspiration or vibratory stage.

5. Collection: Light-weight shells are removed via air suction, while the heavier kernels are graded and collected via the primary discharge chute.

Pistachio Sheller Frequently Asked Questions

Does the shelling process damage the pistachio kernels?

No. Professional cracking machines are calibrated to apply just enough force to crack the shell. By adjusting the precision rollers, the machine ensures a high rate of whole kernels and keeps wastage to an absolute minimum.

Can the machine handle different varieties of pistachios?

Yes. The ADDAMS Pistachio Sheller features adjustable pressure settings and roller gaps. This allows it to handle various sizes and moisture contents, from sweet snacking pistachios to hard-shelled bitter varieties.

What maintenance is required for high-volume operation?

Routine maintenance involves checking the alignment of the rollers and cleaning the sieves to ensure no residue interferes with performance. Because we use food-grade stainless steel and hardened alloys, the machine is resistant to wear and rust.

How do I separate the shells from the kernels after cracking?

While the sheller focuses on the cracking action, ADDAMS offers optional integrated Air Separators or Vibratory Classifiers. These modules use aspiration to lift away the lighter shells, leaving the clean, heavy kernels behind.
