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.

Ventilames® are placed in the channels positioned in the foundations.

Ventilames® are manufactured with dense steel to take a weight of 7 tonnes.

Ventilames® are 500mm or 380mm in width.

Ventilames® have shaped edging on all 4 sides to stop the grain falling into the ventilation channel.

Ventilames® must be covered by 2m of grain prior to switching on the ventilation.

Privé SA has been manufacturing perforated flooring since 1970.

Perforated floors are made of Z275 galvanized steel.

Privé perforated floors consist of a set of floorboards for the cell surface. The diameter of the ventilation holes is 1.3 mm. The perforation is suitable for cereals and rapeseed.

Perforated floor supports have a top edge bent at 90° to avoid shearing the floorboards.

The height of the perforated floor’s galvanized supports is 340 mm or 475 mm, and the height under the floor is 295 mm or 430 mm.

All sealing strips between the cylinder and the floorboards are included in the Privé offer. Ventilation inlets can be 340 mm or 500 mm in diameter, and conveyor inlets 550 mm high and 625 mm wide.

The narrow gap between the perforated floorboards prevents grain and impurities from getting trapped between the boards.

The sweeper auger hooks onto the grooved flaps on the periphery of the floor, preventing the auger from slipping.

The ventigaines® can be moved when a building is empty to permit the surface to be used for a different purpose.

The ventigaines® are 836mm long and 330mm high .

The diametre of the Ventigaines openings are 1.5mm with a 23% perforation.

The recommended air flow in the tunnels is 6500m3/hour and the air diffusion capacity of the tunnels is 2500m3/hour/linear metre.

The air intake diameters are 340mm or 500mm.

Water is an essential element of life, but it can also be a powerful weapon against fire, depending on the capacity stored. Water tanks are reservoirs that store large quantities of water for use in emergency situations, such as fires. These tanks are also used for non-potable rainwater harvesting, liquid storage and as reservoirs for sprinkler systems.
