The Suction Type Gravity Destoner Food Processing Equipment represents a critical cleaning solution in grain processing, designed to remove heavy impurities such as stones, clods, and metallic particles from various grains. Operating on the principle of differential specific gravity and air classification, this equipment achieves an impressive 99.9% stone removal efficiency, ensuring grain purity and protecting downstream processing equipment from damage. With processing capacities ranging from 1.2 to 12 tons per hour across different models (TQSX85B to TQSX168), it accommodates diverse production scales from small mills to large food processing facilities.
The destoner's innovative design combines mechanical vibration with controlled airflow to separate impurities, making it suitable for processing paddy, wheat, corn, soybeans, and various oilseeds. Its compact footprint and modular construction allow easy integration into existing processing lines, enhancing overall cleaning efficiency without requiring extensive facility modifications.
The equipment features an adjustable inclined sieve deck (10-14 degrees) that creates differential movement between grains and heavy impurities. Combined with upward airflow (1.2-1.3 m/s), this system effectively stratifies materials, with grains floating on the air cushion while stones and heavy particles descend to the separation outlet.
An external centrifugal fan provides consistent airflow with adjustable volume (3200-7800 m³/h depending on model), ensuring optimal separation across different grain types and moisture levels. The sealed air circulation system minimizes energy loss and prevents dust emission into the workplace.
Rubber damping bearings and precision-balanced vibration mechanisms reduce operational noise to below 80 decibels. This not only improves working conditions but also allows installation in noise-sensitive areas without additional soundproofing.
Quick-release sieve panels allow for easy cleaning and replacement, with minimal tools required. The self-aligning bearings with anti-loosening devices reduce maintenance frequency, extending service intervals to 3000 operating hours under normal conditions.
Installed at the initial stage of grain processing lines, the destoner removes physical impurities from raw grains, protecting subsequent equipment such as hullers, mills, and polishers from abrasive damage and reducing maintenance costs.
In seed processing facilities, the equipment ensures high-purity seed stocks by removing inert matter that could compromise germination or seed quality. The gentle handling preserves seed viability while achieving thorough cleaning.
For food-grade grain processing, the destoner plays a critical role in meeting food safety standards by eliminating potential contaminants that could cause product recalls or health hazards. It effectively removes stones that could break teeth or damage processing equipment.
Optimal performance occurs with grain moisture between 12-15%. Higher moisture levels increase grain density, reducing stratification efficiency, while excessively dry grains may be carried out with impurities due to lower density. The airflow and vibration settings can be adjusted to compensate for moisture variations within ±2%.
Daily tasks include cleaning the sieve surface and checking air filters. The sieve tension should be inspected weekly, and worn sieves replaced when openings show significant wear (typically after 6-8 months of continuous operation). The fan impeller should be inspected quarterly for dust buildup that could affect airflow.
Yes, the equipment is adjustable for various grain sizes by changing sieve meshes and adjusting airflow. Specialized sieve configurations are available for small grains like millet (0.8mm mesh) up to large grains like soybeans (5mm mesh), ensuring effective separation across the entire range of common cereals and oilseeds.
