Referring to fig. 1 to 3, the invention discloses an electric heating device for tobacco leaf modulation, which comprises a curing barn and a cyclone steam-water separator, wherein the cyclone steam-water separator forms a circulation, moist airflow is pumped out from the curing barn by the cyclone steam-water separator, and dry airflow is input into the curing barn again after water is drained. Wherein a plurality of heating modules 40 and a power supply control system 13 for supplying power to each heating module 40 are arranged in the curing barn. A cyclone-type steam-water separator 12 is arranged at the left end of the baking room, a door 11 is arranged at the right end of the baking room, and a plurality of power supply control systems 13 are arranged at the upper end of the baking room. The air supplementing module is communicated with the air return layer and is used for supplementing fresh air, and the supplemented fresh air naturally enters the circulation after being dehumidified by the cyclone-type steam-water separator. The whole device adopts closed circulation and has little pollution to the environment.
The baking room is in a cuboid shape, four layers of spaces are divided from top to bottom in the baking room through three horizontal plates and are respectively called as a wind supply layer 21, a heating layer 22, a carrying layer 23 and a return air layer 24, and only the carrying layer 23 is provided with an inlet and an outlet on the side and a door 11 for temporarily sealing the inlet and the outlet; of course, the supply air layer 21 and the return air layer 24 need to be connected to the cyclone 12 by pipes. The output end of the cyclone-type steam-water separator 12 is connected with the air supply layer 21, the output end is connected with the air return layer 24, and the liquid discharge end directly discharges the condensate to the outside of the device. For convenience of reference, the three plate members will be hereinafter referred to as an upper plate 31, a middle plate 32 and a lower plate 33. Three plates are all provided with a plurality of hollow holes for air flow to pass through. Considering that the lower plate 33 is used for supporting the tobacco leaves and a frame for containing the tobacco leaves and is subjected to larger gravity, a plurality of supporting ribs are arranged between the lower plate 33 and the bottom of the curing barn to avoid the deformation of the lower plate 33; while the space formed between the support ribs communicates with the air outlet of the return air layer 24, the design mainly ensures that the support ribs do not obstruct the air flow movement.
The support ribs may be cylindrical, at which time the air flow is free to flow in the return air layer 24. In this embodiment, all the support ribs are strip-shaped plates, and at both ends of each support rib in the length direction, a space defined between two adjacent support ribs faces the air outlet of the air return layer 24, and at this time, the airflow flows along the support ribs in the air return layer 24. The fore and aft ends of the support ribs do not reach the fore and aft ends of the return air layer 24.

In this embodiment, the left end of the air supply layer 21 is close to the cyclone-type steam-water separator 12, and the air flow reaches the right end of the air supply layer 21 and is continuously heated. At this time, when the left heating module 40 is normally operated, the right heating module 40 needs to reduce the amount of heat generated. Thus, the left air flow enters the carrier layer 23 after being heated, and the right air flow enters the carrier layer 23 after being additionally heated, so that the temperature uniformity of the air flow in the carrier layer 23 is satisfied.
Preferably, in order to mix the air flow uniformly and then flow to the carrier layer 23, a plurality of turbulence modules 50 are further included in the device. Each the vortex module 50 is installed at the side that the upper plate 31 is close to the middle plate 32, the vortex module 50 includes a cask structure 51 and a plurality of centers on the mouth 52 of arranging to one side of cask structure 51 circumference, set up a plurality of fretwork holes on the cask structure 51, each the outline of mouth 52 of arranging to one side is the quadrant ellipsoid (refer to figure 3 specifically, the ellipsoid here is only approximate), each the circular arc that the end of giving vent to anger of mouth 52 both had with the mouth 52 position of arranging to one side is tangent, again towards the afterbody of adjacent mouth 52 of arranging to one side, and the afterbody that strikes adjacent mouth 52 of arranging to one side is dispersed when the air current flows out around the circumference of cask structure 51, further mixes with the air current that the structure 51 released. In fig. 3, the upper plate 31 is turned upside down to show only the heating module 40 and the turbulator module 50, and the air flow is from bottom to top in the angle of fig. 3.
In other embodiments, the upper plate 31 is a flat plate, and then a plurality of circular holes are formed on the flat plate, and finally the heating module 40 is installed. Preferably, in order to improve the turbulence effect, the turbulence module 50 is uniformly distributed on the upper plate 31 at a position avoiding the heating module 40, and the hollowed holes and the inclined vents 52 of the turbulence module 50 are used as the hollowed holes of the upper plate 31. In fig. 2, for simplicity, the heating module 40 and the spoiler module 50 are not all shown, and it can be understood that the above-mentioned two modules are arrayed to obtain the solution. Referring to fig. 2, in another embodiment, there are three power control systems 13, each power control system 13 controls three arrays of heating modules 40 and turbulator modules 50, respectively, and the upper plate 31 may not have a hollowed-out hole between two adjacent arrays.
In this embodiment, the outermost diameter of the turbulent flow module 50 is 8-14cm, the outermost diameter of each heat pipe 42 of one heating module 40 is 8-14cm, the outer diameter of each heat pipe 42 is 1-1.5cm, and the inner diameter wall thickness is 1-2 mm.
Preferably, the output end of the cyclone separator 12 is branched into three outlets, and then the three outlets are uniformly arranged along the width direction of the blowing layer 21, and the input end of the cyclone separator 12 is branched into three inlets, and then the three inlets are uniformly arranged along the width direction of the return air layer 24. In other embodiments, an outlet or an inlet of the cyclone separator 12 may be connected to the air supply layer 21 and the air return layer 24 with larger left end areas through a funnel structure, so as to ensure uniform air supply and air return. In order to further improve the air supply and extraction effect, an air pump is further added to the outlet branch of the cyclone-type steam-water separator 12.
In the whole circulation, the smart application of the cyclone-type steam-water separator 12 plays a role in providing airflow force and removing moisture in the airflow; the drying efficiency of the cyclonic steam-water separator 12 is higher than that of conventional evaporator condensation. In order to allow the airflow to be uniformly heated and then discharged to the loading layer 23, the blowing layer 21 functions as a buffer zone, allowing the airflow to accumulate in the blowing layer 21 and to enter the heating layer 22. In the heating layer 22, the heating modules 40 at different positions can easily control the heating amount, so that the temperature in the whole curing barn is kept at the same level, and the scheme is easier to manufacture the tobacco leaves with uniform and good quality.
