Grain Destoner

---

Indpro's Destoner is the ideal solution for removing high density contamination from a continuous flow of grains such as, rice, wheat durum wheat, corn (maize), rye, soybeans, oats, buckwheat, spelt, millet and rice to name a few.

The deck comprises of a perforated screen, through which an upward draft is created by centrifugal fan. Due to difference in density of product and the contaminants, the heavy particles such as stones are retained at the bottom of this fluidized mass and product remains a float. Air velocity can be adjusted to achieve the optimal degree of separation. The oscillating action of the screen causes the heavy particles to work their way to the upper end of the deck from where they are expelled through stone outlet. The stone-free grain floats on cushions of air toward the product outlet located at the lower end of the deck. Discharge occurs at both outlets through a rubber chute, which avoids air ingress.

The Destoner machine is used in various application such as rice mills, grain mills, flour mills etc. In this grain destoner air volume can be adjusted to achieve an optimal degree of separation.

The throughput capacity vary according to the type of product to be handled and contamination in it. Variety of products can be handled – Rice, Wheat, Millets, Sorghum, Barley, Malt etc. Typically, the capacity ranges from 8 TPH to 20 TPH.
