Gravity De-stoning: By means of De-stoners, the heavy impurities such as stone, glass are separated out. It is operated under negative pressure, which will not only remove the heavy impurities, but also ensure clean environment.

This gravity de-stoner is based on gravity separating. It is a common oilseed cleaning equipment of edible oil processing project and vegetable oil extraction plant. With the synthetic action of air-flow, sifting and vibrating, stones mixed in the oil materials will be removed. There are two layer of screen in this stone cleaning machine, so that to clean both light and heavy impurities efficiently and completely. Besides, it is equipped with double vibrate motor to achieve balanced and efficient cleaning work. If you are planning for a large vegetable oil plant, this optimized designing destoner should be your best choice. 

Features of This Oilseeds Cleaning Machinery

  • Two options: with or without air-recycling system;
  • Easy operation and maintenance;
  • High specific capacity;
  • Reliable and excellent stone separation and efficient cleaning;
  • Advanced design and excellent fabricating; 

Working Principle of the Seed Cleaning Machine

It is normally design with two-layer-sieve. The key part, sieve box is supported by hollow rubber springs and it is driven by one or two vibrators. Through the feeder on the up of the machine, vegetable seeds such as soybean and sunflower seeds are fed in. Then, while the screen vibrating and the air flowing, according to different specific gravity, the materials will be stratified on the pre-separation screen. Light impurities on the top and heavy impurities at the bottom. Final separation of the stones from the seeds materials is accomplished by a countercurrent of air. The stone-free materials will be discharged through the squeezed rubber valves. Adjust the inclination of the screens and the air volume to achieve the best cleaning effect.
