Background
At present, the main equipment for baking tobacco leaves in China is a standard intensive baking room, and coal is used as energy. The tobacco baking has strict temperature and humidity time curves. The means for controlling the temperature of the curing barn is to control the firepower of the coal-fired furnace, and the means for controlling the humidity is to carry out the moisture removal through a moisture removal window of the curing barn. In the tobacco leaf baking process, the moisture is discharged timely. The relative humidity of the dehumidifying airflow is high, the temperature (40-60 ℃) of the dehumidifying airflow is higher than the ambient air temperature, and a large amount of low-temperature waste heat is carried. Therefore, at present, the intensive tobacco curing barn has the following three disadvantages:
1. wasting energy and polluting environment. The existing baking room adopts fire coal as heat supply energy, the heat loss of the moisture-removing air flow is usually 10 to 20 percent of the lower heating value of the fuel, and can reach more than 25 percent when the heat loss is serious. The heat loss not only increases the consumption of redundant fire coal, but also discharges more harmful gas quantity and pollutes the environment.
2. The flue-cured tobacco quality varies from person to person and is not easy to control. The fire coal of the bulk curing barn needs to be controlled manually, and the curing process needs to be attended by people, so that the labor cost is high.
