Our green walnut peeling machine is designed to remove the green outer husk from freshly harvested walnuts efficiently, without adding water during the peeling process. Shuliy Machinery provides this walnut processing equipment for farms, agricultural cooperatives, walnut processors, and commercial processing plants that need a faster alternative to manual peeling or traditional water-based methods.
With a chain-fed conveying system, multiple independent channels, and inclined stainless-steel blades, the machine continuously cuts and removes the green husk while minimizing unnecessary squeezing between walnuts. The large model can process more than 6 tons of green walnuts per hour, with a normal capacity of around 6–8 tons/h, making it suitable for large-scale walnut processing.
What Is a Green Walnut Peeling Machine?
Freshly harvested walnuts are covered by a thick green outer layer known as the green husk or green hull. This outer layer needs to be removed before the walnuts enter subsequent processing stages such as washing, drying, grading, and storage.
A green walnut peeling machine is designed specifically for this initial processing stage. Instead of removing the hard walnut shell, the machine focuses on cutting and separating the soft green outer husk.
It can also be described as a:
- Walnut hulling machine
- Walnut husking machine
- Walnut hull removing machine
- Green walnut husk remover
- Walnut processing machine
The exact terminology can vary between markets, but the purpose is the same: efficiently remove the green husk from freshly harvested walnuts.

How Does the Green Walnut Hulling Machine Work?
The machine uses a combination of chain conveying and inclined blade cutting to remove the green husk.
Fresh green walnuts enter the feeding section and are distributed into multiple channels. The chain system continuously moves the walnuts forward while the stainless-steel blades make repeated cuts into the green husk.
The 45° inclined blade arrangement is designed to imitate the cutting action used when green husks are removed manually. As the walnut moves through the machine, it passes through multiple cutting points, allowing the green husk to be progressively opened and separated.
The general working process is:
Fresh green walnuts → Multi-channel feeding → Chain conveying → Repeated blade cutting → Green husk removal → Peeled walnuts discharge
The walnuts are processed through individual channels rather than being heavily accumulated in one peeling chamber. This helps reduce excessive squeezing and provides a more controlled feeding and peeling process.
45° Stainless-Steel Blades for Continuous Cutting
One of the key features of this walnut peeling machine is its inclined stainless-steel blade design.
The blades are installed at approximately 45°, creating an angled cutting action as the walnuts travel through the machine. Instead of relying mainly on squeezing or friction, the machine uses repeated cutting to open the green husk.
During the complete peeling process, a walnut can pass through more than 100 cutting actions from feeding to discharge. The repeated cutting helps separate the green husk progressively rather than attempting to remove the entire husk in one operation.
This design is particularly useful for fresh walnuts with relatively firm green husks.
Dry Walnut Peeling Without Water
A major advantage of this green walnut peeling machine is its waterless dry peeling process.
Traditional walnut husk removal methods may involve water, soaking, or other pre-treatment processes. These steps can increase water consumption and extend processing time.
Our machine works without adding water during the peeling process.
Main benefits include:
- No water required for the peeling process
- Lower water consumption
- Less wastewater generation
- Reduced cleaning requirements
- No soaking stage
- Faster processing after harvesting
- Lower operating costs
For walnut processing areas where water resources are limited, dry peeling can be a practical solution.
No Need for Long Soaking Before Peeling
Freshly harvested mature walnuts can be processed directly after harvesting without relying on a 3–5 day soaking period for husk softening.
This allows processors to move more quickly from harvesting to mechanical peeling:
Harvest → Green husk removal → Further processing
Shortening the waiting period can be particularly useful during the walnut harvest season, when large quantities of walnuts need to be processed within a limited period.
It also reduces the need for temporary storage of freshly harvested walnuts before peeling.
10 Independent Channels for High-Capacity Processing
For customers with higher production requirements, Shuliy Machinery offers a 10-channel green walnut peeling machine.
The feeding system uses multiple chain sections and cross-shaped baffles to organize walnut movement. The machine has 10 independent feeding and peeling channels, allowing walnuts to enter the peeling area in a more organized way.
This channel design helps prevent large quantities of walnuts from being concentrated in the same area and reduces unnecessary mutual squeezing during peeling.
The result is a more continuous feeding process that is suitable for commercial walnut processing.
Green Walnut Peeling Machine Capacity
The large 10-channel model has a capacity of:
More than 6 tons/hour, normally around 6–8 tons/hour.
The actual output can vary depending on factors such as walnut variety, maturity, green husk condition, feeding uniformity, and operating conditions.
For smaller processors, we also provide lower-capacity options.
| Model | Channel | Drive | Capacity | Suitable For |
| Large model | 10 channels | 2.2 kW geared motor | 6–8 t/h | Large processors and cooperatives |
| Medium model | 6 channels | 1.5 kW geared motor | About 3.5 t/h | Small and medium processors |
| Tractor-driven model | Multiple-channel design | Tractor PTO | About 3.5 t/h | Orchard and field processing |
Three Green Walnut Peeling Machine Options
Different walnut processing operations have different production requirements. Therefore, we offer several configurations.
1. 10-Channel Green Walnut Peeling Machine
This is the high-capacity option for commercial walnut processors.
With a 2.2 kW geared motor and 10 independent channels, it can process more than 6 tons of green walnuts per hour, normally reaching around 6–8 tons/h.
It is suitable for:
- Large walnut processing plants
- Agricultural cooperatives
- Commercial walnut processors
- Large-scale farms
2. 6-Channel Green Walnut Hulling Machine
The medium model uses a 1.5 kW geared motor and has a capacity of around 3.5 tons/hour.
It is a practical choice for customers who do not require the capacity of the 10-channel model but still want to replace labor-intensive manual peeling.
It can be used by:
- Small walnut processors
- Medium-sized farms
- Agricultural cooperatives
- Local processing workshops
3. Tractor-PTO Driven Walnut Peeling Machine
For orchard operators who prefer mobile processing, we also offer a tractor-driven configuration.
The machine is powered through the tractor’s PTO system, eliminating the need for a separate electric motor.
Its capacity is around 3.5 tons/hour, making it suitable for processing walnuts directly in orchards.
This can be useful when transportation costs are a concern. Green husks can be separated close to the harvesting area, while the peeled walnuts can then be transported for further processing.
What Happens After Green Walnut Peeling?
Removing the green husk is only the first stage of walnut processing. After peeling, the walnuts can enter additional processing equipment depending on the final product and processing requirements.
A typical processing flow may include:
Green walnut harvesting → Green husk removal → Washing → Drying → Grading → Storage or further processing
Further processing includes:
Walnut Grading → Walnut Shelling → Shell and Kernel Separation → Walnut Kernel Grading
For commercial walnut processing projects, Shuliy Machinery can also help customers select equipment for subsequent processing stages.
Is This Machine Suitable for Your Walnut Processing Business?
A green walnut peeling machine can be a good choice if you need to process a large volume of freshly harvested walnuts within a short harvest season.
The right model mainly depends on your daily walnut volume and working environment.
Before selecting the walnut peeling machine, it is also useful to consider the walnut variety, maturity, green husk condition, required capacity, available power supply, and whether the machine will operate in an orchard or a fixed processing facility.
