The walnut green husk peeling machine is a professional dehusking unit engineered for primary walnut processing. It removes the green outer husk from freshly harvested walnuts using a fully dry process, eliminating the need for traditional pile-heaping ripening, water soaking, or manual peeling. With capacity options from 3.5 to over 6 tons per hour, this machine serves orchards, small-to-medium processors, and large-scale factories seeking automated walnut husking.
Compared with traditional wet or manual methods, this walnut husk removing machine delivers cleaner peeling, lower kernel damage, and zero wastewater discharge. The bionic chain-blade cutting system adapts to different walnut sizes, while the stainless steel blade assembly ensures long service life and food-safe operation. It is the ideal choice for walnut growers and processors upgrading from labor-intensive dehusking methods.
Taizy has specialized in nut processing machinery for over 20 years, with equipment exported to more than 30 countries. Every walnut green husk peeling machine is manufactured under the Q/HSY 001-2024 production standard and supported by a 12-month warranty with lifetime technical assistance.

How Does the Walnut Dehulling Machine Work?
The walnut dehulling machine uses a chain-blade peeling mechanism built around two core cutting assemblies:
- Upper blade assembly: Straight blades mounted evenly on a driven chain, cutting into the green husk at a 30-degree angle.
- Lower blade frame: C-shaped fixed blades arranged with buffer springs calibrated to walnut shell strength. Side limiters keep blades moving only vertically, allowing automatic adaptation to different walnut diameters.
- Stainless steel cutting edges: Set at a 45-degree angle for clean, precise cutting.
As walnuts pass through the blade gap, each nut receives more than 100 high-frequency cuts during a single cycle. This removes the green husk thoroughly while keeping the inner shell intact and minimizing breakage.
Waterless Dry Peeling Process
The fresh walnut peeling machine operates without water at any stage. Freshly harvested walnuts can be fed directly into the machine without the traditional 3–5 day pile-heaping period or water soaking. This delivers three key advantages:
- Better product quality: Walnuts retain freshness and kernels stay white.
- Environmental compliance: Zero wastewater discharge, no treatment facilities needed.
- Resource recovery: Removed husks can be returned to the field as organic fertilizer.
Automatic Feeding and Separation
The chain-plate feeding system arranges walnuts evenly before they enter the peeling chamber, preventing blockages. After processing, two separate discharge outlets release:
- Finished products: Clean, dehusked walnuts
- Rejects: Unpeeled or damaged nuts
This automatic separation reduces the need for manual sorting after peeling.
What Materials Can This Walnut Husker Machine Process?
The walnut husker machine is designed primarily for green-husk walnuts at the early post-harvest processing stage. It is suitable for:
- Orchard field operation: Mobile tractor-driven model peels walnuts directly at the harvest site, with husks returned to the soil.
- Small and medium processing plants: Medium model balances capacity and investment cost for family farms and small cooperatives.
- Large-scale factories: 6TH-6000 model delivers high-volume continuous production for commercial processors and agricultural cooperatives.
This machine is commonly used before walnut drying, storage, or further processing into snack products, walnut oil, or packaged retail nuts.
Why Choose a Fresh Walnut Peeling Machine Over Traditional Methods?
| Advantage | Benefit |
|---|---|
| Immediately after harvest | No waiting for pile-heaping ripening, preserving freshness and kernel whiteness |
| Dry operation | No water consumption, no wastewater, eco-friendly production |
| Wide model range | Fixed, medium, and mobile models cover all working scenarios |
| Durable construction | Metal frame, wear-resistant blades, buffer-protected cutter assembly |
| Labor savings | One operator can manage the machine, output tens of times higher than manual peeling |
| Automatic separation | Independent outlets for finished products and rejects reduce sorting labor |
| Food-safe materials | Stainless steel blades and contact parts resist corrosion |
| Low maintenance | Few wear parts, simple daily care, long service life |
How Does the Bionic Cutting Technology Improve Peeling Quality?
Traditional walnut husking methods face several challenges that directly impact
| Customer Pain Point | Traditional Method | Machine Solution |
|---|---|---|
| Slow processing speed | Manual peeling: 50–100 kg/h | Mechanical output: 3,500–6,000 kg/h |
| Kernel darkening | 3–5 day pile-heaping causes quality loss | Immediate processing preserves kernel whiteness |
| Water waste and pollution | Wet peeling requires large water volumes | Dry process uses zero water, zero discharge |
| High labor cost | 5–10 workers needed for peeling | Single operator sufficient |
| Inconsistent peeling results | Variable quality across batches | Bionic blade system adapts to walnut size for uniform results |
| Difficult husk disposal | Wet husks create waste management problems | Dry husks become organic fertilizer |
What Do Customers Say About the Walnut Green Husk Peeling Machine?
A walnut processing cooperative in China’s Yunnan province purchased the 6TH-6000 model to handle their annual harvest of over 2,000 tons of raw walnuts. Before installation, the cooperative relied on 15 manual workers for husking, processing only 800 kg per day with inconsistent quality and frequent kernel damage.
After deploying the walnut husk-removing machine, the cooperative reported:
- Daily throughput: Increased from 800 kg to over 48 tons
- Labor requirement: Reduced from 15 workers to 2 operators
- Kernel damage rate: Dropped from 12% to under 3%
- Processing time: Reduced from 3 weeks to 5 days for the same harvest volume
The cooperative manager noted that the immediate dry peeling process preserved kernel whiteness, which directly improved their selling price to European buyers.
