Green walnut shell peeling machine

The green walnut shell peeling machine is a professional piece of post-harvest processing equipment for fresh walnuts. This model features a dry peeling mechanism that operates without water, effectively removing the green husks while preventing tannin-related staining or quality degradation.

It adopts a one-to-one feeding design to avoid squeezing and damage to walnuts during processing, delivering a high peeling efficiency suitable for large-scale production. With a processing capacity of 6–8 tons per hour, it offers stable and efficient performance to meet the demands of commercial walnut processing operations.

By replacing labor-intensive manual peeling work, this machine significantly cuts labor costs and improves overall processing efficiency. It eliminates the risk of hand irritation caused by husk tannins and ensures clean, uniformly peeled walnuts with good appearance and preserved quality.

How does the green walnut peeling machine work?

The green walnut peeling machine removes the outer green husk from fresh walnuts through a gentle yet efficient dry peeling process, with no water needed.

1. Controlled Feeding: Fresh green walnuts are fed into the machine and guided into individual, one-to-one channels by specially designed cross-shaped baffles on the feed chains. This ensures each walnut moves through the process separately, without squeezing or bumping into others.
2. Dry Peeling Mechanism: Inside the peeling section, rotating components create controlled friction against the walnuts. The tough green husk is rubbed and stripped away cleanly, while the hard inner shell remains undamaged. The dry peeling method avoids the tannin staining and water-related quality issues common with wet systems.
3. Automatic Separation & Discharge: As the process finishes, the peeled walnuts and removed husks are automatically separated. Clean walnuts exit through the main discharge port, while waste husks are expelled separately, ready for collection or disposal.

This continuous, automated workflow lets the machine process 6–8 tons of green walnuts per hour, delivering high peeling efficiency with minimal breakage and consistent results.

Walnut husk peeling machine advantages

• Innovative Dry Peeling Technology: The waterless dry peeling design eliminates the need for rinsing, making the process eco-friendly and energy-efficient, while avoiding tannin-related walnut discoloration.

• Superior Peeling Performance: The 45° angled stainless steel blade design simulates manual cutting, delivering over 100 precise cuts per walnut for thorough, clean peeling without damaging the inner shell.

• No Pre-Processing Required: Walnuts can be peeled immediately after harvesting, skipping the 3–5 day waiting period for ripening with ethylene. This preserves freshness and keeps kernels bright white.

• High Efficiency & Large Capacity: Available in multiple models: the 10-channel large version processes 6+ tons/hour, the 6-channel medium version handles ~3.5 tons/hour, and the PTO-driven mobile model suits on-site orchard use.

• Cost-Effective & Labor-Saving: Automated peeling drastically cuts labor costs. The mobile version even allows husks to be returned directly to the field as fertilizer, saving transportation and disposal costs.

• Durable & Low-Maintenance Build: Constructed with high-quality stainless steel and chain blade structures, the machine offers reliable performance with minimal upkeep.
