The ratio of effective volume between tempering layer and drying layer of traditional paddy dryer in batch was usually 4~8, and some problems such as power consumption and damaged paddy caused by moving parts were increased during continuous operation. Therefore, paddy dryer of multi-drying layer in batch was designed, which the ratio of effective volume between tempering layer and multi-drying layer was less than 1, and the technique of intermittent circulating combined static drying and cycle drying was applied. Spot testing has showed that the technique can reduce the power consumption by 4...
