Abandon the cost of improvement.
Brief description
Fig. 1 is the principle schematic of a kind of multistage hot air drying system that the present invention provides.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1, it is the preferred embodiment of a kind of multistage hot air drying system that the present invention provides, it includes：Control dress
Put, air draft house steward 1, exhaust fan 2 and at least two groups drying units 3, described in every group, drying unit 3 is all total by described air draft
Pipe 1 is connected with described exhaust fan 2.
Described drying unit 3 includes drying oven 31, the stop valve 32 with driver and drying air fan 34, described dry
Dry baking oven 31 is provided with air inlet 301 and exhaust outlet 302, the air inlet 301 of described drying oven 31 pass through pipeline with the external world
Ambient air connects, and the exhaust outlet 302 of described drying oven 31 is connected with described air draft house steward 1 by pipeline, described stop valve
32 are arranged on the pipeline that described drying air fan 34 is connected with described air draft house steward 1, the end of described air draft house steward 1 and described row
The air inlet connection of wind blower fan 2, in drying unit 3 described in every group, the driver of stop valve 32 is connected with described control device respectively
