The most economic and ecological method for the conservation of cereals.

Cold storage is especially beneficial for rice, corn, wheat, barley, soya bean, sunflower seed, sorghum, cottonseed, green coffee, alfalfa granules and compound feed, … Ideal for seed conservation.

It is applicable in silos and warehouses. In the case of silos, the refrigerator is connected in place of the aeration fan. Its installation is usually immediate, not requiring additional works. In the case of warehouses and warehouses, there must previously be a special system of air conduction, either above or below the pavement. Our technical department will advise you in this regard for the conservation of grains.

Process of conservation of grains and seeds

The cold air produced by CONSERFRIO® is conducted to the lower part of the silo. This air begins to cool the grain of the lower layers, pushing the heat, which crosses the entire mass of grain upward absorbing its heat, and escapes in the form of hot air through the upper openings of the silo. The cooling ends when the air escaping from the grain mass is cold. In the case of refrigeration of warehouses, the process is analogous to that which takes place in silos. Cereal is a bad conductor of heat, that is, it acts as a good insulator. The heat radiation on that cold grain, even inside a metal silo or warehouse, has little influence. Therefore, it does not require isolation for optimum grain conservation.

Advantages of the conservation of seeds and grains

It avoids the typical problems of the conservation of seeds: development of heat, insects, fermentation, molds, toxins, weight loss due to the metabolism of the grain, condensation of water. It allows higher humidity contents in the grain, without risk, thus avoiding the expensive and dangerous use of chemical treatments against insects. The product is stored in the best conditions. Operating costs are lower than storage costs with traditional systems. The CONSERFRIO® equipment is normally amortized during the first year of use.
