电晕风干燥实验的研究

在自制的电晕风干燥装置上,对水进行了干燥实验.通过改变放电间隙、针状电极的数目和放电电压,对影响电晕风干燥速率的因素做了初步的研究.实验结果表明:放电间隙越小,针状电极数目越多,输出电压越高,干燥速度越快.在此基础上,又对土豆片进行了干燥试验.

Experimental Study on Electrical Corona Wind Drying

With a self-made electrical corona wind drying equipment, a drying experiment for water was carried out. By changing the distance and voltage between the two electrodes, the factors related to the drying speed are qualitatively studied. The experimental results show that the closer the distance between the two electrodes, the more the number of needle like electrodes; and the higher the voltage between the two electrodes, the faster the drying speed. On the basis of these conclusions, drying for a piece of potato is also studied.
