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.
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
