The fully automatic walnut cracking machine can quickly shell walnuts with skin into whole kernels. Taizy offers three types of walnut shelling machines based on different capacities. The shelling rate is over 99%, the whole-kernel rate is above 70%, and the capacity ranges from 200 to 1000 kg per hour.
All parts in contact with the walnuts are made of food-grade 304 stainless steel, keeping the kernels clean and safe during shelling. The machine is easy to clean and simple to operate — just pour walnuts into the feed inlet, and you will get shelled walnut kernels.
This machine can shell walnuts of different varieties and sizes. It can also shell almonds, pecans, chestnuts, and other hard-shell nuts. It is widely used in nut processing plants, food factories, agricultural processing centres, and export companies.
Why Choose a Walnut Cracking Machine？
- Suitable for a variety of walnuts, such as pecan nut, hazelnut
- Compared with a hand-operated sheller, the walnut sheller is more efficient
- It runs smoothly and takes up little space
- Simple operation, no pollution
- It is durable and easy to maintain
- Manufacturers’ direct, inexpensive
- We also have a reliable pre-sale and after-sales guarantee
How Does the Walnut Cracking Machine Work?
The walnut shelling machine is made of two main parts: a stator and a rotor.
When the machine is running, walnuts enter the gap between the stator and rotor. The shells are broken by continuous and even pressure.
The gap can be adjusted to match different walnut sizes. Before shelling, it is recommended to grade the walnuts by size. Then adjust the gap according to the walnut size. This ensures stable batch shelling, clean shell removal, and a low kernel breakage rate.
Types of Walnut Shelling Machines
Taizy classifies its machines into three types based on different capacities: TZ-300, TZ-600, and TZ-1000.
Type 1: TZ-300
Machine Introduction
This machine is mainly used for shelling walnuts, summer fruits, and other hard-shell nuts. Different walnut varieties may result in different outputs and whole-kernel rates. By adjusting the gap between the inner and outer drums, the machine can achieve the best shelling effect. Walnuts are fed from the top and discharged after shelling through the internal system.
Machine Parameters
| Parameter | Specification |
|---|---|
| Capacity | 200–300 kg/h |
| Weight | 230 kg |
| Power | 1.5 kW |
| Voltage | 380 V, 50 Hz |
| Whole-kernel rate | 70% |
| Dimensions (L×W×H) | 1.2 × 0.7 × 1.3 m |
| Material | Carbon steel |

Type 2: TZ-600
Machine Introduction
This machine is mainly used for shelling walnuts and other hard-shell nuts. Output and whole-kernel rate vary depending on the walnut variety. The gap between the inner and outer drums can be adjusted to achieve optimal shelling. Airflow can also be controlled to ensure effective shell and kernel separation. Walnuts are fed from the top, shelled inside the machine, and discharged through the bottom outlets—one for shells and one for kernels.
Machine Parameters
| Parameter | Specification |
|---|---|
| Capacity | 500–600 kg/h |
| Weight | 260 kg |
| Power | 2.2 kW, 50 Hz |
| Voltage | 220V/380 V |
| Whole-kernel rate | 70% |
| Dimensions (L×W×H) | 1.2 × 0.7 × 1.6 m |
| Material | Carbon steel |

Type 3: TZ-1000
Machine Introduction
The single-stage walnut cracking machine is a basic device for shelling walnuts, with an adjustable gap. After shelling, some small walnuts may remain uncracked and need to be separated and reprocessed by adjusting the gap.
Taizy offers a three-stage walnut cracking machine, which can grade walnuts into three sizes and complete shelling in a single pass, improving efficiency and reducing manual reprocessing.
Machine Parameters
| Parameter | Specification |
|---|---|
| Capacity | 1000 kg/h |
| Machine Dimensions | 3500 × 1950 × 2500 mm |
| Weight | 350 kg |
| Power | 4.3 kW |
| Voltage | 380 V, 50 Hz |
| Material | Carbon steel |

Walnut Cracking Machine Operating Procedure
Walnut Grading & Preparation
- Grade walnuts to ensure uniform size. Remove mud, stones, and high-moisture walnuts to reduce breakage and protect the machine.
Adjust Stator & Rotor Gap
- Set the gap according to the walnut size. Run a small test batch first, then fine-tune the gap for optimal batch shelling.
Start Machine & Feed Evenly
- Start the machine without a load, then feed walnuts evenly and continuously. Avoid overloading to prevent blockage or uneven shelling.
Shelling & Automatic Separation
- Walnuts are cracked between the stator and rotor. Shells and kernels are automatically separated via airflow or screening systems, improving product cleanliness and reducing manual sorting.
Output Inspection & Fine Adjustment
- Check kernel integrity and breakage rate. If breakage is high or some walnuts remain unshelled, adjust the gap and continue operation.
Cleaning & Maintenance
- After the operation, clean residual shells. Regularly check the stator, rotor, and drive components to ensure stable long-term performance.
