Frequently Asked Questions

What is a seed destoner machine used for?

A seed destoner removes stones, glass, and other heavy impurities from grains and pulses, ensuring clean and market-ready seeds.

Which crops require destoning before processing?

Destoners are essential for wheat, lentils, chickpeas, sesame, sunflower, and other crops that often contain stones or heavy foreign materials mixed with seeds.

What is the difference between pressure type and vacuum type destoners?

Pressure-type destoners push air upward to lift lighter seeds while heavy impurities fall, whereas vacuum-type destoners use suction to achieve the same separation. Both ensure precise and gentle cleaning.
