Working Principle

  • Fluidization and Stratification: As raw materials enter the screen surface, they are subject to vibratory force and upward airflow.
  • Gravity Separation: Lighter peanut kernels remain suspended and flow smoothly downward to the discharge outlet. Heavier stones and metallic impurities stay close to the screen surface and move upward driven by vibration, achieving precise gravity separation.

Key Advantages

  • High Efficiency: Combines gravity destoning with air suction technology to achieve a stone removal rate of over 99%.
  • Zero Damage: Precise airflow control ensures effective impurity separation without damaging the delicate skin or kernels of peanuts.
  • Equipment Protection: Prevents hard impurities from entering downstream shelling machines or colloid mills, extending the service life of blades and grinding discs.
  • Eco-friendly Operation: Features a compact structure, adjustable frequency, low energy consumption, and dust-free operation.

Core Components Breakdown

Technical Highlights: Equipped with dual unbalance vibration motors featuring adjustable eccentric blocks.

Operational Benefit: Provides stable, low-noise linear vibration that ensures consistent material throw angles without damaging fragile peanut skins.

Technical Highlights: Made of food-grade 304 stainless steel or wear-resistant galvanized mesh with precision-punched fish-scale or woven openings.

Operational Benefit: Optimizes fluidization, allowing lighter peanuts to float upward on air currents while heavier stones settle onto the sieve deck and move toward the discharge outlet.

Technical Highlights: Features an integrated air regulation valve with a high-pressure centrifugal fan and transparent observation window.

Operational Benefit: Allows operators to finely calibrate air volume according to crop moisture and grain density, ensuring complete stone separation without blowing out light peanuts.

Technical Highlights: Constructed with thick-walled laser-cut structural steel and high-tensile composite rubber shock absorbers.

Operational Benefit: Isolates dynamic forces to protect floor structures, reduces operating vibration noise, and ensures structural stability during 24/7 continuous industrial processing.

Technical Highlights: Includes an adjustable flow gate and internal distribution plate at the inlet.

Operational Benefit: Prevents material clogging and spreads the peanut layer evenly across the full width of the sieve deck for maximum processing capacity.

Applications

  • Suitable Materials: Ideal for peanut kernels, soybeans, sesame seeds, and sunflower seeds.
  • Target Industries: Widely used in peanut shelling plants, peanut oil pressing facilities, peanut butter manufacturing plants, and grain cleaning centers.

Why Use a Peanut Destoner Machine?

Protecting Downstream Machinery & Reducing Maintenance Costs
Harvested raw peanuts frequently contain hard stones, metallic particles, and clods. If these enter processing lines without prior cleaning, they can severely damage the grinding discs of a Colloid Mill or break the blades of a Nut Cutting Machine. Integrating a Peanut Destoner Machine intercepts these rigid impurities at the source, significantly extending the service life of high-value equipment.
High-Precision Gravity Separation
Stones and mud clods often share a similar size and appearance with peanut kernels, making them difficult to detect using standard Sorting Machines or manual inspection. A Gravity Destoner leverages upward airflow and vibratory specific gravity separation to efficiently remove identical-sized impurities in bulk without damaging the delicate peanuts.

Can this machine be used for other crops besides peanuts?

Yes. While optimized for peanuts (in-shell or kernel), it is a versatile gravity de-stoner suitable for a wide range of granular crops including soybeans, sesame seeds, sunflower seeds, coffee beans, and wheat. The inclination angle of the sieve, airflow volume, and vibration frequency can all be easily adjusted to handle different grain sizes and densities.

What is the separation efficiency for small stones or mud clods of similar size to peanuts?

Our machine achieves a de-stoning efficiency of ≥99.5% for stones and heavy impurities. For mud clods that have the exact same density and size as peanuts, gravity separation alone may be less effective; in such cases, we recommend pairing the de-stoner with our preliminary rotary screening drum or clod crusher prior to de-stoning.
