grain destoner technical analysis and manufacturing specifications
We manufacture high-performance Air Screen Cleaners with gravity tables for reliable cleaning of sesame and beans, removing defective kernels to achieve up to 99% purity. Capacity is 7–15 TPH with a 12.8 kW power rating. CE/SGS certified.
The Air Screen Cleaner with Gravity Table is a high-performance, integrated solution designed for professional cleaning and grading of grains and pulses. By combining airflow separation, particle sieving, and gravity-based sorting into a single streamlined unit, this machine removes a wide range of impurities—from light dust and husks to heavy defective kernels—helping you achieve consistent, high-purity end products aligned with industry requirements.
Designed for both versatility and precision, the system is suitable for processing sesame seeds, soybeans, mung beans, coffee beans, and chickpeas. Deployed as a standalone cleaning unit or integrated into a full-scale seed processing plant, it removes shriveled, insect-damaged, and moldy grains. With the right setup, it can reach a final product purity of up to 99% with minimal seed loss.

It is highly versatile and suitable for sesame seeds, soybeans, mung beans, kidney beans, chickpeas, coffee beans, peanuts, and chia seeds.
While standard cleaners primarily remove size-based impurities, the gravity table uses differences in specific gravity to remove shriveled, moldy, or insect-damaged seeds that may otherwise appear similar in size to healthy kernels.
Yes. The system is designed for flexible deployment and can operate as a standalone unit or be seamlessly integrated into a complete seed processing plant.
Typical production capacity is 10 to 15 tons per hour, depending on the material type and the required purity level.
Yes. It is equipped with an environmental cyclone duster system designed to protect the warehouse environment and support operator health.
Yes. The machine features interchangeable screens, allowing you to adjust mesh size to accommodate different grains and seeds.
