Walnut Shelling Machine | Pecan Cracker
Walnut shelling machine is mainly used for hard shelling of walnuts to achieve separation of shell kernels. high output, low breaking rate.
In the initial processing of walnuts, shelling is a key step that affects both kernel yield and product quality. The walnut shelling machine is specifically designed for walnuts and other hard-shelled nuts, enabling continuous and stable shelling operations while maintaining a certain rate of whole kernels. The machine features a reasonable structure and simple operation, making it suitable for small to medium-sized walnut processing plants and primary agricultural product processing projects.
Application of The Automatic Walnut Cracker Machine
This walnut cracking machine is primarily used for the mechanical shelling of walnuts and can also be applied to certain hard-shelled nuts such as macadamia. The shelling efficiency may vary for walnuts of different varieties and moisture content. The machine’s structure can be adjusted to accommodate a variety of raw material conditions, meeting common walnut processing requirements.
Machine Structure and Working Principle
Our walnut cracking machine consists of two main components: the stator and the rotor.
During operation, walnuts enter the gap between the stator and rotor. Under continuous and uniform pressure, the walnut shells are crushed. The gap size can be adjusted according to the walnut size, ensuring a consistent shelling effect.
We usually recommend that customers grade the walnuts before shelling. This allows the gap to be adjusted according to different walnut sizes, ensuring clean shelling, a high whole-kernel rate, and reduced kernel breakage. To support this, we also offer a corresponding walnut grading machine to help complete the entire processing workflow.
Features of Commercial Walnut Cracker
- Walnut sheller is a new generation of hard walnut peeling machines with a compact structure, full automation, and easy operation.
- It has the advantages of stable and reliable performance, high shelling efficiency, low breakage rate of the walnut kernel, good sorting, and low loss rate.
- Pecan cracker uses a 380V power supply, motor power of 1.5KW, small size, energy saving, easy to use, easy to operate, and easy to transport.
- With high processing efficiency, one people can operate and can process hard walnuts about 200kg-400kg per hour.
Safety and Material
We understand that safety in food processing is of utmost importance. Therefore, all parts that come into contact with walnuts are made of food-grade 304 stainless steel, ensuring that the walnuts remain uncontaminated during processing. The walnut shelling machine body is made of carbon steel, providing a sturdy and durable structure.
Specifications of Pecan Cracker Machine
- Processing Capacity: 200–400 kg/h
- Whole Kernel Rate: Approximately 70% (depends on walnut variety and condition)
- Machine Weight: 160 kg
- Motor Power: 1.5 kW
- Operating Voltage: 380 V / 50 Hz
- Dimensions (L × W × H): 1.2 × 0.7 × 1.3 m

This configuration is suitable for continuous operation and meets the basic daily processing capacity required for walnut shelling.
Automatic Walnut Shelling Line Configuration
The walnut shelling machine is designed only for walnut shelling, with the primary function of cracking whole walnuts. If complete separation of walnut shells and kernels is required, a kernel and shell separator or a screening machine can be used in combination. Common basic configurations include:
- Elevator: Automatically feeds walnuts, reducing manual labor
- Walnut Shelling Machine: Performs the main shelling operation
- Sieving Machine: Separates shells and kernels preliminarily, improving the efficiency of subsequent processing
This combination enables continuous operation, reduces manual involvement, and is suitable for customers with certain production capacity requirements.
Adjustment and Operating Recommendations
To ensure optimal shelling results, we generally recommend that customers:
- Grade the walnuts according to size;
- Adjust the gap between the stator and rotor according to walnut size;
- Regularly check the machine’s operating condition and clean the interior to maintain long-term stable processing capacity.
- Equipped with a vibrating screen for nuts to separate shells and kernels.
By following these simple steps, shelling results during batch production can be more consistent, and the walnut kernel breakage rate is significantly reduced. Our company can also integrate these machines with elevators and conveyor belts to form a fully automated shelling line, if required.
