Description
Technical Field
The utility model relates to a flue-cured tobacco heating device.
Background
After tobacco leaves are harvested by tobacco production farmers, fresh tobacco leaves are purchased by a tobacco purchasing mechanism after being baked and yellow, and at present, the fresh tobacco leaves are baked by the farmers through a heating mode through a device called a tobacco baking room. At present, the traditional coal-fired tobacco curing barn: through at the built-in hot air flue of tobacco flue-curing house, the in-process that the outside chimney of tobacco flue-curing house passes through the heat at the passageway gives off the hot air flue heating to the tobacco flue-curing house in, at the bottom of the utilization ratio, most heat is discharged through the chimney, has also discharged a large amount of smoke and dust simultaneously, pollutes seriously. The heat dissipation of the hot channel is uneven, and the tobacco leaves close to the hot channel are usually over-high in temperature, so that the quality of the baked tobacco leaves is reduced. Temperature control is controlled by manually controlling firepower, temperature fluctuation is large, manual operation space is large, the temperature control is easy to lose control, a humidity control manual observation thermometer is controlled through a manual air port, 24-hour manual field operation is needed, and requirements on skills and physical strength of personnel are high.
In addition, another traditional tobacco flue-curing house is a biomass tobacco flue-curing house: through setting up a heat transfer room in tobacco flue-curing house outside one side, granule combustor is established in the heat transfer room, is equipped with the air heater between heat transfer room and the tobacco flue-curing house, and the air heater blows the tobacco flue-curing house in with the heat that granule combustor gived off through tobacco flue-curing house top air intake, provides hot-blast for the tobacco leaf is dry, discharges from tobacco flue-curing house bottom air outlet again. The temperature generated by the combustion machine is required to be too high, and the required hot air temperature is obtained by mixing the heat exchange chamber with external cold air and is sent into the tobacco curing house. In the process, the heat loss is large, the temperature in the curing barn is not uniform, the cured tobacco at the air inlet has poor quality, and the cured tobacco at other parts cannot reach the unified standard. The design of business turn over wind gap is violated moisture and is expanded the principle that upwards flows naturally after the heating, forces moisture to discharge from below, and the wind-force of fan is enough big, leads to the excessive emission of humidity, does not have the accurate accuse humidity of method. The particle combustor discharges a large amount of smoke and dust during combustion, and has serious pollution and high noise during combustion.
Because the coal-fired tobacco curing barn does not meet the requirements of emission reduction and energy conservation at present, the coal-fired tobacco curing barn also adopts electric heating tobacco curing, such as an air source heat pump tobacco curing barn: the design is basically the same as the biomass flue-cured tobacco, only the heating source is changed into the heat pump by the granule combustor, the environmental protection problem of the granule combustor is solved, but the accuracy of temperature and the control of temperature can not reach the requirement, the heat pump heating is through air compression heating, the highest temperature that can cross is limited, the temperature can not reach the temperature that needs in the back end drying technology, need increase the electric heater and supply heat, temperature control is out of control easily, and electric energy consumption is big.
