Grain Destoner Machine

 

 

A grain destoner machine is a device that separates impurities from grains by utilizing the differences in density and suspension speed between grains and stones, using mechanical wind and a reciprocating screen surface. This cocoa bean stoner separates stones from grains by adjusting pressure and vibration frequency based on the differences in specific gravity and density. This grain destoner machine is suitable for processing crops such as cocoa beans, coffee beans, corn, peanuts, sesame seeds, soybeans, wheat, millet, barley, buckwheat, castor beans, oats, rice, peppercorns, cottonseed, camellia, sorghum, and sunflower seeds.

1. The rectangular work surface provides uniform and adjustable airflow.
2. The work surface's vertical and horizontal tilt are adjustable, allowing for quick work surface changes.
3. The work surface's vibration frequency is controlled by an inverter and can be adjusted continuously.
4. This grain destoner machine uses a silent downblowing fan for low noise.
5. An external air pressure gauge ensures clear airflow adjustment. An external grease nipple facilitates maintenance.

 

This grain destoner machine utilizes positive pressure, utilizing airflow and vibration friction to act on the material. Heavier materials sink to the bottom and move upward, while lighter materials float to the surface and flow downward, achieving gravity separation. This grain destoner machine can be used to sort a variety of dry granular materials, removing grass clippings, dust, stones, immature kernels, insect-damaged kernels, moldy kernels, and broken kernels. Its destoner efficiency exceeds 99.5%.
