Paper Title:
Experimental Study on the Temperature Variation of a New Tobacco Curing Barn with Double-Way Ventilation
  Abstract

In China, there is a vast area of tobacco producing, and the production condition in various regions is different. It is difficult for the traditional bulk tobacco curing barns with air rising to adjust the area with all conditions, and the intrinsic quality of cured tobacco is difficult to guarantee. We study on a new tobacco curing barn with double-way ventilation, and we analyze its performance through experiments. We tested the change of the temperature field in both the new tobacco curing barn with double-way ventilation and the traditional tobacco curing barn with air rising, the result shows: (1) Air moves in the new tobacco curing barn with double-way ventilation from top to bottom, compared with the traditional bulk tobacco curing barn with air rising, the new tobacco curing barn has a smaller amount of airflow, and it also has a small temperature difference on the same horizontal plane and a reasonable temperature difference on vertical direction, this is good for the curing of different maturity tobacco leaves; (2) Fuel of the new tobacco curing barn with double-way ventilation is one-time added, so the heat supply is stable, and the temperature changes quite gentle, but fuel of the traditional tobacco curing barn with air rising is many-time added, the temperature changes dramatic. (3) The new tobacco curing barn with double-way ventilation has forced ventilation channel and enhanced moisture channel to strengthen the ability of natural ventilation, so when power outages and other emergency situations happen, there is natural air convection in the tobacco curing barn, but the simple tobacco curing barn with air rising totally could not avoid the harm caused by power outages and other emergency situations. This research could provide reference for the design and application of new curing barn later.
