Why should corn be cooled?
Spontaneous heating of the grain often causes great damage. Systematic hygiene regulations and the call for natural treatment of the produce grain without chemical substances are standards that must be attained. We have an answer for all these demands: GRANIFRIGOR™. The GRANIFRIGOR™ cooling device is used to cool down grain immediately after the harvest, independent of the weather. This effective method prevents the spoiling of freshly harvested grains, which heats up spontaneously due to its cellular respiration. Carbon dioxide, water and heat are released by this respiration – with extensive consequences: Loss of dry substance as well as the development of insects, microbes and mildew. Spontaneous heating depends on the grain’s moisture and temperature. The principle is also valid for oil seeds such as rapeseed. Since we know how grain “functions”, the GRANIFRIGOR™ operates according to two successful principles:
1. Prompt cooling to below +13 °C once the grain has been stored in: This puts insects into diapause so that they have no chance to multiply (see illustration below). Additionally the development of mildew is effectively prevented, respiration losses are minimized, and drying expenditures are also reduced by the drying effect of the cooling.
2. No ventilation with non-conditioned outside air: Grain seeds are hygroscopic. This means that depend-ing on the temperature an equilibrium develops bet-ween the moisture content of the seeds and the relative humidity of the ambient air. Moisture develops if dry grain is exposed to humid air. The grain begins to spoil. Therefore aeration by fans is completely dependent on the weather. Furthermore, the ambient temperature during harvest time is usually much too high.
