Silo ventilation and emptying: Venticône®

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

The Venticône ® is designed to empty the silo completely by gravity and to ventilate the grain.

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

With a Venticône ®, there’s no need for a sweeping screw. Manual emptying of the residual slope exposes the silo operator to mycotoxins, which constitutes a hazard. The Venticône ® allows grain to be ventilated, and improves food hygiene for consumers and livestock, as the grain is not in contact with the concrete (unlike flat storage).

The time saved enables the farmer to carry out work with greater added value.

The Venticône ® also provides ventilation for stored products such as wheat, corn, barley, rye, soybeans… The cone elements have 1.6 mm deep gills to facilitate ventilation. If necessary, the cone elements have pan-head bolts for easy emptying.
The operator can easily clean the underside of the Venticône ®.

In short, the Venticône ® is a silo equipment with many advantages.
