Background
With the rapid development of the tobacco industry, the standard of the tobacco leaf demand is higher and higher, the production of high-quality tobacco leaves is the main direction of the future development, and the science and technology cigarette development becomes the main melody of the modern development of the traditional tobacco agriculture. The tobacco curing barn is matched by an advanced scientific technology, the internal quality and the external quality of tobacco leaves are continuously improved, the labor intensity and the production cost are reduced, the economic benefit is increased, and the tobacco curing barn becomes a necessary means for tobacco to mainly compete for the market at the present stage. In four links of tobacco seedling raising, planting, picking and baking, tobacco baking is an essential key link in tobacco production, and is also a link with the most uncontrollable quality, the highest risk, the largest loss and higher cost in the current tobacco production. Therefore, the key problems of keeping the enthusiasm of farmers for tobacco planting and solving the stable tobacco production are solved.
Aiming at the problems existing in tobacco leaf baking, the problem that the intensive production and management of tobacco leaves are greatly promoted is mainly solved by optimizing the structure of a bulk curing barn and matching with a special tobacco leaf field control instrument at present, but because the bulk curing barn mainly adopts coal for heat supply, the problems that the quality of the cured tobacco leaves is influenced by inherent unstable combustion, uneven temperature rise and stabilization and the like exist, the ineffective energy consumption is too high, the fuel waste is caused, and a large amount of SO is discharged2、CO2、NOXAnd pollutants such as particulate matters cause environmental damage and the like. In addition, the existing tobacco leaf field control instrument takes the baking temperature and humidity as control parameters, and the maturity of tobacco leaves is different, so that the automatic control effect is not good, the intelligent degree and the automation degree are low, the baking control is relatively complex, the labor level is high, the tobacco leaf adaptability is poor, and the quality after baking needs to be improved.
Aiming at the problems of the coal-fired curing barn, various heating modes such as biomass granular fuel, electric heating, natural gas, heat pump and the like are adopted, and a series of new problems are brought although some problems of coal-fired heating can be avoided. For example, biomass particles are distributed dispersedly, the density is low, the distribution of the biomass particles by manufacturers is less, the yield is low, the development is slow, and the biomass particles generate a large amount of tar during low-temperature combustion to cause the fault of combustion equipment. Therefore, the baking technology of the biomass fuel baking room has a certain distance for completely realizing intelligent and precise baking by breaking through the existing baking technology. Although the electric heating is fast in heating, the energy consumption is high, the heat efficiency is low, and energy is not saved. In addition, when the problems of power failure caused by natural disasters such as thunderstorm rain and the like, fuel supply interruption caused by heating and setting of fuels which are difficult to obtain nearby and the like are encountered in the baking period, the single or simple baking room with the combination of the electric heating, the biomass heating, the natural gas heating and the like can only be forced to stop the primary baking of the tobacco leaves, and huge economic loss can be caused. And the heat pump heating mode needs to reform the power grid and additionally configure a standby power supply in the early period, so that the one-time investment is high, and the heat pump heating mode is difficult to popularize. Therefore, the research on the baking and baking room which can adapt to various energy sources and can intelligently integrate and utilize the advantages of various energy sources is the key for improving the baking quality of the tobacco leaves.
