Silo ventilation and emptying: the Venticone®

In a silo, the stored product is emptied by gravity. The Venticone ® is a conical structure placed at the bottom of the silo. This equipment has many advantages over a flat bottom.

The Venticone® is designed to completely empty the silo by gravity and to ventilate the grains.

When the product is stored in a flat-bottomed silo, during emptying through the central trough, a residual slope is formed. The residual slope is the grain remaining in the silo after gravity emptying. The residual slope can vary in volume depending on the physical properties of the product. The residual slope can cause problems for grain storage (mold, pests, etc.) so the silo must be cleaned regularly. The Venticone ® allows almost complete gravity emptying of the grains.

With a Venticone ®, a sweeping screw is unnecessary. Manual emptying of the residual slope exposes the silo operator to mycotoxins, which constitutes a danger. The Venticone ® allows the ventilation of the grain and better food hygiene for consumers or for livestock because the grain is not in contact with the concrete (unlike flat storage). 

The working time saved allows the farmer to carry out work with higher added value.

The Venticone ® also provides ventilation for stored products such as wheat, corn, barley, rye, soybeans, etc. In fact, the cone elements have 1,6 mm deep vents to facilitate ventilation. If necessary, the cone elements have pan head bolts to facilitate emptying.
The operator can easily clean the underside of the Venticone®.

In summary, the Venticone ® is a silo equipment with many advantages.
