Walnut Fruit Washing Machine

GONGMAO Equipment Manufacturing, founded in 1994, with 32+ experience, specializes in advanced nuts and food processing machinery, particularly complete processing solutions for customers worldwide.

Many walnut processors focus quality upgrades on downstream peeling, drying and de-enzyming, yet overlook the critical pre-washing step. Raw walnuts carry heavy sediment, dust, impurities and mold residues from harvesting, storage and transit. Poor pre-cleaning cannot be offset by advanced downstream processes, directly hurting product appearance, food safety and export inspection pass rates.

Traditional manual rinsing and simple soaking deliver limited cleaning with dead zones, uneven results, low efficiency and high water use. Manual handling risks secondary contamination and residual stains, leading to inconsistent batch cleanliness. This is a key reason many factories fail high-end retail and export food safety checks and cannot reach premium pricing. Standardized pre-washing equipment is essential for clean, high-grade walnut kernels.

Addressing heavy impurities, incomplete cleaning, inconsistent cleanliness and high labor costs, this walnut fruit washing machine is core front-end equipment for walnut deep processing lines. Designed for deep cleaning of raw walnuts and kernels, it supports large-scale standardized pretreatment for all walnut specifications.

Unlike simple soaking and rinsing, it features multi-flow circulating scrubbing and flexible tumbling cleaning. It fully covers surface gaps to remove stubborn sediment, dust, impurities and mold debris for thorough dead-zone-free cleaning. Gentle tumbling prevents impact damage to shells and kernels, preserving raw material integrity.

Built with a circulating filtration system, it separates wastewater and impurities and recycles clean water. This water-saving eco-friendly design maintains consistent cleaning quality and avoids cross-contamination. Fully automatic inline operation cuts labor costs and eliminates the low efficiency and unstable quality of manual washing.

As the first step of the full deep processing line, the walnut fruit washing machine works independently or integrates seamlessly with kernel extraction, de-enzyming, peeling and drying lines. Smooth process flow supports uniform downstream peeling, stable drying and consistent appearance. It controls cleanliness at the source, delivering spotless walnut kernels that fully meet food safety and export standards.

Premium walnut products start with clean pretreatment. This professional walnut fruit washing machine enables standardized pre-washing, effectively lifting product grade and market premium, and helping manufacturers secure high-end snack, gift box and export orders.
