The drying experiments of corn in three types of dryer were carried out, breakage susceptibility of corn was measured. The results show that it is related to temperature and velocity of air, initial moisture content of corn, as well as the cooling methods. The temperature was the most remarkable effect factor on breakage susceptibility. Among three types of dryer, the concurrent flow dryer with counter flow cooling has the least effect on breakage resistance, the breakage susceptibility of corn after drying was the smallest.
