Grain is one of our most important staple foods, it is the staff of life. It is cultivated and harvested with great care. Proper storage must be ensured to maintain quality and to avoid quantity losses.

Spoilage of freshly-harvested grain is caused by self-heating of the grain due to cellular respiration. Carbon dioxide, water, and heat are released through cellular respiration. Self-heating depends on grain moisture and grain temperature. The result is loss of dry matter, as well as development of microbes, mildew, and insect feeding, e.g. through the grain weevil.

These losses can be effectively prevented through cooling to under 13°C. Cooling preservation is the most natural method for limiting quality and quantity losses associated with grain storage. Chemical additives are not required. Moreover, cooling preservation offers additional business administration advantages that should be interesting for every storage facility.
