Grain Dryer

Hundreds of millions of tonnes of wheat, corn, soybean, rice and other grains as sorghum, sunflower seeds, rapeseed/canola, barley, oats, etc., are dried in Jinhua mobile grain dryers each year. In the main agricultural countries, drying comprises the reduction of moisture from about 17-30% w/w to values between 8 and 15%w/w, depending on the grain. The final moisture content for drying must be adequate for storage.

When drying corn kernels it is important to keep in mind that cracks and fractures in the corn can lead to many problems in both the storage and processing. The major problem that occurs from high temperature drying and then rapid cooling of the grain is stress-cracking. Stress-cracking is when fractures become present in the corn endosperm. Stress-cracked kernels often absorb water too quickly, are more likely to become broken, and are increasingly susceptible to insect and mold damage during dry storage. In order to reduce the amount of grain that is lost due to stress-cracking, Jinhua Machine Company developed the newest corn dryer with special drying methods to keep medium temperature and slow cooling which has got the Chinese government patented products certificate.
