Destoner

With a 7–10 tons/hour capacity and 6.25 kW power, this gravity destoner has a 100% stones-removal rate for sesame, beans, groundnuts, and rice. It is available as a 50 sets/month supply with 10–15 working days delivery, and is supplied with SGS, CE, and SONCAP documentation.

The destoner is also known as a gravity destoner. Its operating principle is based on the combination of specific gravity, airflow, and vibration. By adjusting the vibration frequency and air volume, it effectively removes heavier impurities such as stones that are similar in size to the material particles. It is suitable for small, medium, and large particle materials, including millet and sesame; mung beans and soybeans; and adzuki beans and broad beans.
