Comparison of the Baking Effect of an Air Energy Heat Pump Intensive Baking Room Using Different Humidity Removal Methods
In order to explore the cost reduction and efficiency improvement baking effect of new energy baking houses in Xiangyang,Hubei,comparative experiments on the baking effects of three different dehumidification methods of air energy heat pump baking room and biomass baking room were conducted.A total of 4 treatments were set up in the experiment,with S1(CK)mobile biomass particle dense baking house as the control;S2 open air energy heat pump dense baking room;S3 closed air energy heat pump dense baking room;S4 composite air energy heat pump dense baking room.The load baking efficiency,key baking temperature control,baking cost,conventional chemical composition of tobacco leaves,and economic benefits of cured tobacco leaves for each treatment are compared and analyzed to verify the baking effect.The re-sults show that compared with biomass baking rooms,the baking efficiency of new energy heat pump baking rooms is slightly lower,but the key baking temperature control is more precise,and the baking cost is reduced;the average cost of dry smoke per unit in the new energy heat pump drying room is only 1.20-1.52 yuan/kg,which is much lower than that in the biomass drying room,with a decrease of 0.69-1.01 yuan/kg,a decrease of 31.22%-45.70%,and a savings of 386.7-543.3 yuan per unit of smoke.The chemical composition coordination of the internal quality of tobacco leaves in the heat pump drying room is improved,and the effect is better with closed and composite methods.The proportion of high-quality tobacco in the closed air enerygy heat pump intensive curing room significantly increased by 5.92 percentage point,and the av-erage price of tobacco leaves significantly increased by 2.27 yuan/kg,with the best total output value.Overall,compared with biomass inten-sive baking houses,heat pump intensive baking houses save labor,reduce costs,improve quality and efficiency,and have a very good promo-tion prospect.
