谷物干燥节能的探讨

本文提出一种谷物干燥的方法,即在低温慢速干燥谷物时,采用分级自动加热气流的方法。用这种方法干燥谷物,干燥机气道的气流自动地处于低温或常温,但它始终具有进行干燥谷物的能力。从试验结果表明,在一定的风量比下,能够收到节能和避免发芽的效果。 本试验的平均能耗是840千卡/公斤水。较一般高温快速干燥法可节能约20％,但所需时间较长。

AN APPROACH OF ENERGY SAVING IN GRAIN DRYING

This paper presents a method of drying grain. It is using a method of grading automatical heating air flow in the low-temperature slow-velosity drying grain. Using this drying grain method,the air flow in the air duct of the drying machine may be in low or normal temperature automatically.But it always has the ability to carry on drying grain. Tie results of the experiments showed that under a definite wind-quantity ratio, we can save the energy consumption on the one hand, and avoid the germination damage of the rice grain on the other.The average energy consumption in the experiments is 840 k cal/kg water.It is 20%lower than the gemeral method of high-temperature rapid drying, but it takes longer time.
