烤房中使用翅片管的密集度對煙葉質量的影響

密集烤房中應用翅片管散熱器對煙葉質量的影響：以普通換熱器為對照,研究瞭翅片管散熱器在密集烤房中應用的效果及其對中上部煙葉外觀質量、化學成分、香氣物質、評吸質量和經濟性狀的影響。結果表明:翅片管散熱器能顯著地改善上部煙葉的外觀質量,而對中部煙葉的改善效果不大。采用翅片管散熱器能在一定程度上改善煙葉的內在化學成分的協調性和感官評吸質量,提高其香氣物質的含量和內在品質。翅片管散熱器對經濟性狀的影響明顯,能顯著地降低每公斤幹煙的耗煤量,提高均價等,有利於節能降耗。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 influe印花地坪nce 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.密集烘烤由於裝煙密度大,節省烘烤用工,有利於提高專業化程度和煙葉烘烤質量,現已成為中國烤煙烘烤的發展方向。但是我國烘烤設備的研究與應用卻相對落後,不能滿足烤煙生產發展的要求,因此,對烤房設備的研究一直是行業熱點。美國密集烤房專傢在熱風循环系統、裝煙設備、燃料利用、排濕系統、密集烘烤工藝等方面不斷完善,逐步形成瞭適應美國經濟狀況、生產方式的先進的商業化生產、商業化運作的現代化、機械化、智能化的密集烤房以及相應的配套設備與技術。隨著我國現代農業發展戰略的實施,烤煙生產組織形式也發生瞭重大轉變。在不斷加大煙葉生產基礎設施建設投入的同時,全面推進煙葉生產的規模化、集約化、專業化和信息化。目前我國密集烤房在加熱設備方面已經取得瞭較大進展。換熱器是工業傳熱過程中必不可少的設備,翅片管散熱器與普通光管換熱器相比具有許多熱性能和經濟上的優點。在合適的條件下,翅片管散熱器不僅可減少換熱器尺寸,而且能提高換熱效率,在制冷、空調和化工等工業領域得到廣泛應用。但是該換熱器在密集烤房設備中的應用研究較少。因此，本研究探討瞭翅片管散熱器在密集烤房中的應用效果，並研究瞭采用該設備後對烤後中上部煙葉質量的影響，旨在為密集烤房設備的改進提供理論依據。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 彩色沥清地坪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.轉載請註明http://www.wxsxsjx.com
