Abstract

The invention relates to the field of tobacco baking, in particular to a uniform-airflow-type efficient tobacco baking room and a low-temperature tobacco baking technology. The uniform-airflow-type efficient tobacco baking room comprises a tobacco baking room body, a heating device is arranged in the tobacco baking room body, a main air pipe, three or more auxiliary air pipes, an air distributionbox and a fan are arranged in the tobacco baking room body, the main air pipe is vertically arranged at the center in the tobacco baking room body, the auxiliary air pipes are distributed around the main air pipe in the mode of being at the equal distance from the main air pipe, the main air pipe and the auxiliary air pipes communicate with the air distribution box, and the air distribution box communicates with the fan; and holes are formed in the main air pipe and the auxiliary air pipes. The uniform-airflow-type efficient tobacco baking room is used, in the tobacco baking process, the dry-bulb temperature is gradually increased from 32 DEG C to 62 DEG C, the wet-bulb temperature is gradually increased from 32 DEG C to 39 DEG C, and the tobacco baking time is 130-150 hours. According tothe uniform-airflow-type efficient tobacco baking room, airflow at all the positions of the tobacco baking room is mixed uniformly, the temperatures and the humidity in all areas in the tobacco bakingprocess are relatively uniform, low-temperature baking can be adopted, not only is fuel saved, but also the time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of flue-cured tobacco, in particular to a high-efficiency flue-cured tobacco room with uniform airflow and a low-temperature flue-cured tobacco process. Background technique [0002] Curing room equipment is an indispensable infrastructure for the development of professional baking and the construction of modern tobacco agriculture. At present, there are mainly two types of curing rooms (horizontal type) and ordinary curing rooms (vertical type), that is, the airflow descending type. room and updraft barn. At present, the high loss rate of curing is the bottleneck restricting the curing of tobacco leaves. It is urgent to reduce the loss of tobacco leaves during curing and improve the utilization rate of heat energy in curing rooms. The limitation of the airflow movement mode in the existing curing barn has caused a large temperature and humidity difference in different areas of the barn barn, and different areas have...
