Tobacco drying room 10 is heated rapidly to predetermined temperature by the hot water in storage water pot 50.
(3) after 50 water temperature of heat storage water pot is reduced to set temperature, the 5th water circulating pump 15 is out of service, starts temperature
Control module 30 is spent, i.e. second circulation water pump 12 starts, and the first refrigeration compressor 32 starts.
(4) humidity control module 20 requires automatic startup according to the humidity of Tobacco drying room 10, starts the side with control
Method is that first circulation wind turbine 21 starts, and third water circulating pump 13 starts, and the running frequency of first circulation wind turbine 21 is done according to tobacco
The humidity variation automatic adjustment of dry room 10.
(5) after Tobacco drying, humidity control module 20, temperature control modules 30, water source hot water heat pump 60 etc. are complete
Portion is stopped, and second circulation wind turbine 17 starts, and the 5th water circulating pump 15 starts, at this point, the heat of Tobacco drying room 10 passes through
First air-water heat exchanger 16 is recovered and is stored in heat storage water pot 50.
The tobacco drying apparatus of present invention embodiment shown in FIG. 1 has the following advantages that：
(1) drying process carries out in confined conditions, and the smell of tobacco is kept, and drying process is not by atmospheric environment shadow
It rings；
(2) it is estimated through design, drying cost declines more than 30%.
(3) after dry, force ventilated mode is taken to cool down, cooling time is saved；
(4) drying process temperature and humidity can be fully according to traditional temperature, humidity with independent control, Tobacco drying
Controlling curve carries out, and mouthfeel and the tradition of tobacco are consistent；
(5) drying equipment utilizes pure driven by power, and drying process does not generate any pollutant；
(6) equipment automatically controls, and equipment is saved a large amount of artificial without manually nursing.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification for all within the spirits and principles of the present invention, being made,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
