Galvanized Grain Aerator OZ-4 / 380V

Grain Aerator OZ-4 is an efficient electric device designed for active ventilation and drying of grain masses during long-term storage in warehouses, silos, and elevators.

Thanks to its galvanized construction, it is corrosion-resistant and suitable for operation even in high-humidity environments. This reliable solution is ideal for owners of small and medium-sized farms who want to effectively preserve the quality of stored grain.

Key Benefits:

• Maintains grain quality by effectively lowering temperature and humidity, preventing mold, fungi, and pest development.
• Extends storage time by eliminating "hot spots" (self-heating zones) that can destroy grain batches.
• Dries and preserves grain by accelerating the drying of freshly harvested grain to safe moisture levels (e.g., <14% for wheat).
• Heats seed material, aiding in preparation for sowing.
• Durable galvanized steel construction ensures longevity and rust resistance.

How It Works:

The device consists of a perforated tube screwed directly into the grain mass and a high-pressure centrifugal fan. Air pushed through the grain cools, dries, and removes excess moisture. It operates in two modes: blowing (air supply) and suction (air extraction).

The blowing mode injects fresh air deep into the grain mass to support cooling and drying. The suction mode effectively removes humid air from inside the storage, reducing the risk of mold, fungi, and spoilage.

Applications:

• Grain warehouses and silos
• Grain piles
• Elevators
• Conservation of wheat, corn, rapeseed, soy, sunflower, flax, and other crops
