The Study Of Utilization Of Central Heating And Thermal Recycling In Tobacco Leaf Curing

This paper reviewed the status of research and development in tobacco bulk curing bam all the world, and analyzed the development trends of bulk-curing in china. Based on the current situation of bulk curing to consider the factors of saving energy, reducing consumption and environmental protection, we conceived and system designed new technical ideas of central heating and thermal recycling in curing. We carry out the experiments in2011and2012, and improved and consummated the systems of central heating and thermal recycling in curing. It was valuable to study in central heating for tobacco leaf bulk-curing and achieved significant effect of thermal recycling in curing, meanwhile, we provided study experience and study data in this field.The successful design of hot-humid gas recycling system made redundant thermal energy and humidity to recycling a reality. Hot-humid gas from hotter bam could be used to heating for colder bam or dampening for cured tobacco leaves, which could save energy, cut costs, reduce residue and waste gas, improve the level of intensification and modernization. These systems resolved the problems of lower thermal efficiency, incapable recycling of thermal energy and higher labour cost. However, these systems had a little deficiency and would be resolved, for all that, it was valuable to study.
