In a silo, the stored product is emptied by gravity. The Venticône® is a cone-shaped structure positioned at the bottom of the silo. This equipment offers numerous advantages over a flat-bottom design.

The Venticône® is designed to fully empty the silo by gravity and to ventilate the grains effectively.

When the product is stored in a flat-bottom silo, emptying it through the central auger can leave behind a residual slope. This residual slope consists of grains that remain in the silo after gravitational emptying and can vary in volume based on the physical properties of the product. This residual slope can lead to issues such as mould and pests, necessitating regular cleaning of the silo. The Venticône® allows for nearly complete gravitational emptying of the grains.

With a Venticône®, a sweep auger becomes unnecessary. Manual removal of the residual mound places the silo operator at risk of exposure to mycotoxins, which poses a health hazard. The Venticône® also ensures proper ventilation of the grain, promoting better food hygiene for consumers and livestock, as the grain does not come into contact with concrete (unlike flat storage).

The time saved allows farmers to focus on more value-added work.

Additionally, the Venticône® provides ventilation for stored products such as wheat, corn, barley, rye, soybeans, …. The cone’s elements are designed with 1.6 mm deep openings to enhance ventilation. If needed, the cone elements are equipped with wing bolts for easier emptying. Operators can also easily clean beneath the Venticône®.

In summary, the Venticône® is a silos equipment that presents many benefits.

The Ventilame® are designed for the ventilation of silos and for ventilating flat-stored grains in warehouses.

The purpose of the the Ventilame® is to ensure the quality of harvested crops.

The Ventilame® are installed on drainage channels integrated into the foundations.

Made from thicker steel, the Ventilame® can support loads of up to 7 tons

The Ventilame® are available in widths of 500 mm or 380 mm.

Each Ventilame® features downward edges on all four sides to prevent grains from falling into the ventilation channel.

Before activating the ventilation system, a minimum of 2 meters of grain must cover the Ventilames®.

Privé SA has been manufacturing perforated floors since 1970.

The perforated floors are made from Z275 galvanized steel.

Privé’s perforated floors consist of a series of floor slats that cover the cell area. The diameter of the ventilation perforations is 1.3 mm, making them suitable for grains and rapeseed.

The supports for the perforated floors feature a 90° bent upper edge to prevent cutting into the floor slats.
The height of the galvanized supports for the perforated floor is either 340 mm or 475 mm, and the clearance under the floor measures 295 mm or 430 mm.

All sealing flanges between the cylinder and the floor slats are included in the Privé offer. Ventilation inlets can have a diameter of 340 mm or 500 mm, while the conveyor inlets measure 550 mm in height and 625 mm in width.

The small gap between the perforated floor slats prevents grain and impurities from getting trapped between them.

The sweep auger engages with the grooved flaps placed around the perimeter of the floor, preventing it from slipping.

When a warehouse is empty, the Ventigaines® can be relocated, allowing the surface area to be repurposed for other uses.

Each Ventigaines® measures 836 mm in length and 330 mm in height.

The diameter of the openings in the Ventigaines® is 1.5 mm, featuring a perforation rate of 23%.

The recommended airflow in the tunnels is 6,500 m³/hour, while the air diffusion capacity of the tunnels is 2,500 m³/hour per linear meter.

Air intake diameters are available in either 340 mm or 500 mm.

Water is a vital element for life, but it can also serve as a powerful tool against fires, depending on the volume stored. Water tanks are reservoirs designed to hold large quantities of water for use in emergencies, such as firefighting. These tanks are also utilized for the collection of non-potable rainwater, the storage of liquids, and as reservoirs for sprinkler systems.
