中文摘要：

针对批次式稻谷干燥机的缓苏层与干燥层有效容积的比值在4~8,需连续循环工作时,增加了动力消耗及运动部件对稻谷损伤的问题,设计多干燥层批次式稻谷干燥机,使缓苏层与多个干燥层有效容积之和的比值〈1,并采用静止干燥与循环干燥相结合的间歇循环烘干工艺。现场试验表明：与现行稻谷干燥工艺相比较,该工艺可减少干燥机循环动力消耗40%,并使干燥机提升、布料、排料机构对稻谷损伤率降低50%,且在保证干燥品质的前提下,比相同容积的批次稻谷干燥机产量提高约3%。

英文摘要：

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 40%,and cut down the damage rate of paddy by 50%,caused by mechanism of material lifting,distributing and discharging compared with the present drying technology.Meanwhile the new type paddy drier in batch can increase production about 3%compared with that of same volume and the drying quality can be ensured.
