A walnut processing plant helps you process large quantities of walnuts through size grading, shelling, kernel-shell separation, and final sorting. We offer a multi-stage walnut shelling line designed for continuous material processing.
The equipment configuration can be adjusted according to walnut size, processing capacity, and kernel quality requirements. The number of shelling machines can also be increased or reduced to suit your project.
What Is a Walnut Processing Plant?
Our walnut processing unit for shelling combines several machines to separate walnut kernels from their hard shells. Rather than relying on a single walnut cracking machine, the complete system handles multiple processing stages.
The main functions include:
- Grading walnuts by size before shelling
- Feeding walnuts into shelling machines at a controlled rate
- Cracking the shells and separating kernels from shells
- Removing stones and residual shell fragments
- Sorting kernels and removing defective pieces
This configuration is suitable for walnut processors who need to handle bulk raw materials and organize multiple processing stages in one production system.
Walnut Shelling Line with a Capacity of 1–1.5 Tons per Hour
The machine configuration in this article is based on a processing capacity of 1–1.5 tons per hour. Of course, we can customize the solution according to each customer’s specific capacity requirements.
- Raw material elevator
- Rotary drum grading machine
- Electromagnetic quantitative feeding hoppers
- Multiple walnut shelling machines
- Kernel collecting conveyor
- Feeding elevator for the separation section
- Kernel-shell separators
- Gravity destoner
- Screening machine
- Final sorting conveyor
The rotary drum grading machine separates walnuts into different size grades. The graded materials are then fed into the corresponding shelling machines.
The number of walnut shelling machines is flexible. For example, a configuration with three or four shelling machines can be considered according to the required throughput, walnut size distribution, and shelling performance. The final configuration should be confirmed through material testing and equipment matching.
How Does the Walnut Processing Plant Work?
1. Raw Material Feeding and Size Grading
An elevator conveys the raw walnuts into a rotary drum grading machine. The machine separates walnuts into four size grades, helping prepare the raw material for the shelling stage.
2. Quantitative Feeding
After grading, electromagnetic quantitative feeding hoppers deliver walnuts to the shelling machines.
This arrangement supports controlled feeding and allows different walnut sizes to enter the appropriate shelling units.
3. Walnut Shelling
The walnut shelling machines crack the hard shells to release the kernels. Their shelling gaps can be adjusted according to walnut size to help balance shell removal and kernel integrity.
Depending on the project, we can match three, four, or another suitable number of walnut shelling machines to the required processing capacity.
4. Kernel and Shell Separation
After shelling, the mixture of walnut kernels and shells is conveyed to the separation section.
The kernel-shell separators separate the two materials and discharge them through different outlets for collection.
