The Structure Optimization Design and Experimental Study of Electric Heating Furnace of Jujube Drying Machines
摘要
Abstract
The electric heating furnace as heat source device at present is widely used in all kinds of drying machines . For ceramics single tube electric heater of application of DH 65 series large jujube hot-air dryer , Based on theory of heat transfer , optimal design for multiple heater triangle combination of electric heating furnace structure .By thermal effect of the improved electric heater analysis shows that under the same condition of the heat transfer , furnace body structure opti-mization to improve heating time of air inside of the electric heating furnace , also increase the heat transfer effect , com-pared with before improvement , Based on two kinds of hot-air drying test furnace body structure showed that the heating time of electric heating furnace is reduced to 10 min and 8℃temperature difference , and temperature stage temperature decreased 6℃, 1℃reduces the temperature deviation .Meanwhile , the improved drying room temperature fluctuation is small , the stability of the temperature is higher , has better temperature control effect .关键词
