1. Natural Air-Drying Method
This traditional method involves spreading freshly harvested walnuts in a dry, well-ventilated, and shaded area. Over time, the green husks will naturally dry, shrink, and crack, making them easier to remove by hand. Although this process is simple and cost-effective, it requires patience—usually taking several weeks.
2. Manual Removal
For smaller quantities, manual dehulling is a straightforward option. Using gloves and a small knife, you can carefully peel off the green skin. Be cautious during this process, as the husk contains juices that can stain hands and surfaces. This method is immediate but labor-intensive.3. Artificial Ripening
Some growers use ethylene or other ripening agents to accelerate the loosening of the husk. This can reduce the waiting period compared to natural drying. It’s a mid-scale method often adopted by small farms looking to speed up the process while maintaining product quality.4. Retting Method
In this technique, walnuts are soaked in water or piled in humid conditions for several days until the husks begin to rot and soften. After that, they become easier to wash or rub off. This method is effective but must be monitored carefully to prevent over-fermentation, which could affect the nut’s flavor and quality.
5. Industrial Mechanical Dehulling
For large-scale walnut processing, mechanical husk removers are the most efficient solution. These machines abrade, crush, or blow off the green husks with minimal damage to the shell. This method ensures high throughput, uniformity, and hygiene—ideal for commercial walnut producers and processors.As this year’s walnut season approaches, Hebei Huadai Group is fully prepared to welcome the harvest.
