Subject to technical changes

Since we know how grain "functions", the GRANIFRIGOR™ operates according to two successful principles:

1. Immediate cooling after grain harvest to below +13° C:

Because of this, insects go into hibernation and have no chance to spread (see fig. below). In addition, the development of molds is effectively prevented, respiration losses are minimized and due to the drying effect of the cooling process, drying expenses can be saved.

2. No ventilation with unconditioned outside air:

Humidity of the ambient air establishes a condition of equilibrium depending on the temperature. Thus, moistening occurs when moist air is introduced to dry cereal and the grain spoils. Therefore, the ventilation with fans is completely dependent on the weather. In addition, the ambient temperature is usually much too high during the harvest season.

Function:

The fan of a GRANIFRIGOR™ grain cooler draws in ambient air (see fig. below). This air is cooled in an air cooler (evaporator) to the desired temperature. The downstream HYGROMAT™ setup warms the cold air again automatically. Thus, the relative humidity is lowered and adapted to the conditions of the grain bed. Moistening, which would be extremely damaging, cannot occur. This cold and dried air is forced through the grain by the air distribution of the flat storage or the silo system. Through the exhaust vents of the storage area, the air flow passes back into the environment. With this exhaust, the absorbed heat and moisture are removed.
