The State Intellectual Property Office (SIPO) made public on August 5 the application for utility model protection of a box-type stacked curing barn filed by Qujing City Tobacco Company in southwest China's tobacco-producing Yunnan Province.

The box-type stacked curing barn developed by Qujing City Tobacco Company comprises a heating room and a leaf tobacco feeding room. The heating room is equipped with a burning furnace, an air-heater and a hot air transmission passage. The leaf tobacco feeding room has guide rails installed at the bottom and both sides. At the foot of a wall of the curing barn adjacent to the guide rails, a guide rail wall higher than the bottom of the leaf tobacco feeding room is installed. An air outlet is opened in the wall adjacent to the heating room, with an air inlet in the lower part. On the guide rails are several independent rolling leaf tobacco feeding boxes made of metal pipes. At the four corners of the leaf tobacco feeding room, supporting rolling wheels are installed.

The patent has contributed to solving the difficult technical problem of poor exchange of air flows in the process of leaf tobacco curing at existing box-type stacked curing barns, which in turn results in relatively high proportions of damaged leaf tobacco including rotten sheets and steamed sheets. Thus, the application of this patent will lead to balanced temperatures and humidity, accelerated dewatering and drying of leaf tobacco, indirect reduction of the cost of leaf tobacco curing, and improvement of the quality of leaf tobacco curing. Enditem
