可调节气流方向的闭式循环热泵烤房的设计应用
Design and application of closed-loop heat pump curing barn with variable airflow direction
摘要
Abstract
To reduce the coal consumption and environmental pollution of tobacco flue-curing equipment and improve the softness of cured leaves, a closed-loop heat pump curing barn with variable airflow direction was designed. The test results showed that the temperature in the designed barn was controlled accurately and stably, and met the temperature and humidity requirements of bulk curing of flue-cured tobacco. The flow rate of condensate water varied at different curing stages, and decreased continuously with the proceeding of curing. Compared with the tobacco cured by coal-fueled bulk curing barn, the tobacco cured by heat pump barn was softer, shrank more obviously widthwise, had more favorable levels of chemical components and more harmonious chemical compositions, and higher sensory quality scores, the cost of labor and energy reduced by 1.88 RMB yuan per kg cured leaves. This technology provides a support for promoting the curing quality of tobacco.关键词
