    密集烤房中应用翅片管散热器对烟叶质量的影响:以普通换热器为对照,研究了翅片管散热器在密集烤房中应用的效果及其对中上部烟叶外观质量、化学成分、香气物质、评吸质量和经济性状的影响。结果表明:翅片管散热器能显著地改善上部烟叶的外观质量,而对中部烟叶的改善效果不大。采用翅片管散热器能在一定程度上改善烟叶的内在化学成分的协调性和感官评吸质量,提高其香气物质的含量和内在品质。翅片管散热器对经济性状的影响明显,能显著地降低每公斤干烟的耗煤量,提高均价等,有利于节能降耗。
    The effect of finned tube radiator on tobacco leaf quality in intensive curing barn: The effect of finned tube radiator on appearance quality, chemical composition, aroma substance, smoking quality and economic characteristics of middle and upper tobacco leaves in intensive curing barn was studied. The results showed that finned tube radiator could significantly improve the appearance quality of upper tobacco leaves, but had little effect on middle tobacco leaves. Finned tube radiator can improve the coordination of chemical components and sensory evaluation quality of tobacco leaves to a certain extent, and improve the content and internal quality of aroma substances. Finned tube radiator has obvious influence on economic characteristics, which can significantly reduce the coal consumption per kilogram of dry smoke, increase the average price, and is conducive to energy saving and consumption reduction. 
    密集烘烤由于装烟密度大,节省烘烤用工,有利于提高专业化程度和烟叶烘烤质量,现已成为中国烤烟烘烤的发展方向。但是我国烘烤设备的研究与应用却相对落后,不能满足烤烟生产发展的要求,因此,对烤房设备的研究一直是行业热点。美国密集烤房专家在热风循环系统、装烟设备、燃料利用、排湿系统、密集烘烤工艺等方面不断完善,逐步形成了适应美国经济状况、生产方式的先进的商业化生产、商业化运作的现代化、机械化、智能化的密集烤房以及相应的配套设备与技术。随着我国现代农业发展战略的实施,烤烟生产组织形式也发生了重大转变。在不断加大烟叶生产基础设施建设投入的同时,全面推进烟叶生产的规模化、集约化、专业化和信息化。目前我国密集烤房在加热设备方面已经取得了较大进展。换热器是工业传热过程中必不可少的设备,翅片管散热器与普通光管换热器相比具有许多热性能和经济上的优点。在合适的条件下,翅片管散热器不仅可减少换热器尺寸,而且能提高换热效率,在制冷、空调和化工等工业领域得到广泛应用。但是该换热器在密集烤房设备中的应用研究较少。因此,本研究探讨了翅片管散热器在密集烤房中的应用效果,并研究了采用该设备后对烤后中上部烟叶质量的影响,旨在为密集烤房设备的改进提供理论依据。
    Intensive flue-curing has become the development direction of flue-cured tobacco in China because of its high loading density, saving labor and improving the degree of specialization and the quality of Flue-cured tobacco. However, the research and application of curing equipment in our country is relatively backward, which can not meet the requirements of the development of flue-cured tobacco production. Therefore, the research on curing equipment has always been a hot spot in the industry. Experts in intensive curing barns in the United States have continuously improved in hot air circulation system, tobacco loading equipment, fuel utilization, moisture exhaust system, intensive curing technology, and gradually formed a modern, mechanized and intelligent intensive curing barn and corresponding intensive curing barns adapted to the economic situation and production mode of the United States. Supporting equipment and technology. With the implementation of China's modern agricultural development strategy, the organization of tobacco production has also undergone a major transformation. While increasing investment in infrastructure construction of tobacco leaf production, we should comprehensively promote the scale, intensiveness, specialization and informatization of tobacco leaf production. At present, China's bulk curing barns have made great progress in heating equipment. Heat exchanger is an indispensable equipment in industrial heat transfer process. Finned tube heat exchanger has many advantages in thermal performance and economy compared with ordinary smooth tube heat exchanger. Under suitable conditions, finned-tube radiator can not only reduce the size of heat exchanger, but also improve the heat transfer efficiency. It has been widely used in refrigeration, air conditioning and chemical industries. However, the application of the heat exchanger in bulk curing barn equipment is few. Therefore, this study explored the application effect of finned tube radiator in intensive curing barn, and studied the influence of this equipment on the quality of upper and middle leaves after curing, in order to provide theoretical basis for the improvement of intensive curing barn equipment.辛苦整理.转载请注明http://www.wxsxsjx.com
