Grain chiller avoids this loss results from insect  activity and mildew growth during storage.

Grain is one of our most vital staple foods. It is farmed and harvested with great care. According to the Food and Agriculture Organisation of the United Nations (FAO), the annual spoilage of the grain harvested worldwide is over 20 %. The major part of this loss results from insect activity and mildew growth. Using the QINGFENG conservation cooling process effectively  revents these losses. Many million tonnes of grain, oil seed, rice, maize, and other cereals are conserved worldwide using this technology.

Preventing weight and quality losses through insects. Originally, conservation cooling was developed for conserving moist grain, before drying. These days, however, more dry grain is cooled than moist –mainly to protect against feeding and proliferating insects.  Losses through insect feeding can effectively cease by cooling the harvested crop to temperatures under 13 °C. If the temperatures are low enough, the insects go into diapause – hibernation – and cannot harm the stored crop.
