Overview

Nut Destoner Machine (1).png

The Nut Destoner Machine is a purpose-built device engineered to eliminate stones, clods, and other heavy contaminants from nuts—including almonds, walnuts, pecans, and peanuts—during processing. Its operation hinges on leveraging the variance in specific gravity between nuts and impurities: through a combination of vibration and airflow, lighter nuts are lifted and transported forward, while denser stones and heavy debris fall through separation gaps or are expelled via side outlets.

Crafted from food-grade stainless steel, this machine offers adjustable vibration frequency and airflow intensity, allowing it to adapt seamlessly to different nut sizes and moisture levels. It comes equipped with a feeding hopper, vibration screen, and dedicated impurity discharge port, ensuring exceptional separation accuracy (up to 99%) while keeping nut loss to a minimum. With its compact footprint, it can be effortlessly integrated into existing nut processing lines or used as a standalone unit, making it a versatile choice for nut farms, processing facilities, and food manufacturing plants.

Product Advantages

Product Advantages

Exceptional Separation Precision: By harnessing the power of gravity and vibration, this machine achieves a 99% accuracy rate in removing stones and heavy impurities, guaranteeing the purity of the processed nuts.​

Broad Nut Compatibility: Its adaptability shines through adjustable vibration frequency and airflow, making it suitable for a wide range of nuts—including almonds, walnuts, pecans, and peanuts—without compromising efficiency.​

Food-Grade Construction: Crafted from 304 stainless steel with smooth, seamless surfaces, it meets stringent food hygiene standards. The design also simplifies cleaning, ensuring hassle-free maintenance.​

High Efficiency with Minimal Waste: Boasting a processing speed of 500-3000kg/h, it handles large volumes effortlessly. Meanwhile, nut loss is kept to ≤0.5%, significantly reducing raw material waste.​

User-Friendly Operation: A digital control panel allows easy adjustment of vibration and airflow settings, eliminating the need for complex training. Even operators with limited experience can master it quickly.​

Durable and Reliable Performance: Equipped with a heavy-duty vibration motor and wear-resistant components, it delivers stable operation over an extended service life, minimizing downtime.

Application Scenarios

Application Scenarios

Nut Farms: Ideal for cleaning freshly harvested nuts such as walnuts and almonds, effectively removing stones and soil clods before storage to prevent damage and maintain quality.​

Nut Processing Plants: Seamlessly integrates into production lines as a pre-processing step—before shelling, roasting, or packaging—ensuring that only pure nuts enter subsequent stages, enhancing overall product quality.​

Food Factories: Essential for removing impurities from nuts used in snack production, including mixed nuts and nut butter, ensuring compliance with strict food safety standards.​

Nut Wholesale Markets: Helps clean bulk nuts to 提升 marketability, meeting the high-quality requirements of retailers and end customers.​

Organic Nut Production: Relies solely on physical separation methods, avoiding chemical cleaning agents. This preserves the organic integrity of the nuts, ensuring they meet organic certification criteria.
