[0023] See also Figure 1 The embodiment of the utility model provides a tobacco leaf moisture-recovery device, comprising a steam generating cylinder 1, a first heating component, a preheating cylinder 4 and a second heating component. A safety valve 11 and a steam outlet 13 are arranged at intervals on the upper part of the steam generating cylinder 1. Baffles 15 are staggered near the upper end of the steam generating cylinder 1. The first heating component comprises a first electromagnetic heating controller 3 and a first inductance coil 2 connected to the first electromagnetic heating controller 3. The first inductance coil 2 is wound and sleeved on the circumferential outer wall of the steam generating cylinder 1. The preheating cylinder 4 is connected to the steam generating cylinder 1 through a connecting pipe 7. The upper part of the preheating cylinder 4 is connected to a water reservoir 9 through a water inlet pipe 8. The second heating component comprises a second electromagnetic heating controller 6 and a second inductance coil 5 connected to the second electromagnetic heating controller 6. The second inductance coil 5 is wound and sleeved on the circumferential outer wall of the preheating cylinder 4.

[0024] Among them, when the present application is used, the steam outlet 13 is connected to the tobacco curing room, and a heat insulation layer is provided between the outer wall of the steam generator cylinder 1 and the first inductance coil 2, and a heat insulation layer is also provided between the outer wall of the preheating cylinder 4 and the first inductance coil 2. The heat insulation layer is made of high-temperature resistant insulating and heat-preserving cotton. The heat insulation layer has a good heat preservation effect, which insulates the steam generator cylinder 1 and the preheating cylinder 4, reduces the heat dissipated to the outside by the steam generator cylinder 1 and the preheating cylinder 4, and has an energy-saving effect.

[0025] The principle of the first heating component is: when the first heating component is in use, the first electromagnetic heating controller 3 is first started, the first electromagnetic heating controller 3 converts the alternating current into direct current, and then converts the direct current into high-frequency and high-voltage electricity. The first electromagnetic heating controller 3 passes the high-frequency and high-voltage electricity to the first inductor 2, and the high-speed changing high-frequency and high-voltage current passes through the first inductor 2. At this time, a high-speed magnetic field change is generated in the first inductor 2. The first inductor 2 is sleeved on the outer wall of the steam generator tube 1. The steam generator tube 1 has eddy currents generated by cutting the alternating magnetic lines of force. The eddy currents cause the carriers in the steam generator tube 1 to move irregularly at high speed. The carriers collide and rub against each other in the steam generator tube 1 to generate heat. The generated heat heats the water in the steam generator tube 1. The principle of the second heating component is the same as that of the first heating component, and this application will not be repeated in detail here.

[0026] Specifically, there are two baffles 15, and the baffles 15 are fan-shaped. The arc-shaped outer edge of the baffle 15 is connected to the inner wall of the steam generator cylinder 1. The baffle 15 is set with the arc-shaped edge tilted inward and downward. During the boiling process of water, the baffle 15 plays a good blocking role to prevent boiling water droplets from splashing into the steam. A water level gauge (not shown in the figure) is also provided on the steam generator cylinder 1. The water level gauge and the steam generator cylinder 1 form a communicating vessel. The liquid level gauge is also called a liquid level gauge or a liquid surface gauge. The water level gauge is a prior art and is not described in detail in this application.

[0027] Combination Figure 1 As shown, the steam generator cylinder 1 and the preheating cylinder 4 are both closed shells at both ends. A safety valve 11 is provided at the upper part of the steam generator cylinder 1. When the internal air pressure of the steam generator cylinder 1 is too high, the safety valve 11 can be opened to discharge the air and relieve the pressure to reduce the internal pressure of the steam generator cylinder 1. In addition, a barometer 12 is also provided at the upper part of the steam generator cylinder 1 to ensure the safety of the steam generator cylinder 1. A drain pipe 16 is provided near the lower end of the steam generator cylinder 1, and a first switch valve 17 is provided on the drain pipe 16. A second switch valve 14 is provided at the steam outlet 13.

[0028] Specifically, the water inlet pipe 8 is provided with a first water pump 81, and the preheating cylinder 4 is provided with a liquid level sensor 41 near its upper end. It should be noted that the parts not described in detail in this application are all prior arts.

[0029] In addition, a temperature sensor 71, a third switch valve 74, a second water pump 72 and a one-way valve 73 are sequentially arranged on the connecting pipe 7. By setting the one-way valve 73, the water in the steam generating cylinder 1 is prevented from entering the preheating cylinder 4. When the temperature sensor 71 detects that the water in the connecting pipe 7 reaches a predetermined temperature threshold, the second electromagnetic heating controller 6 is closed, and the third switch valve 74 and the second water pump 72 are opened, so that the heated water in the preheating cylinder 4 enters the steam generating cylinder 1.

[0030] When the present application is working, the cold water in the water reservoir 9 is pumped into the preheating cylinder 4 through the first water pump 81, the second heating component preheats the water in the preheating cylinder 4 to the set temperature, and then the preheated water in the preheating cylinder 4 is pumped into the steam generating cylinder 1 through the second water pump 72. The second heating component is used to heat the water in the steam generating cylinder 1 to generate the required water vapor, and the generated water vapor is introduced into the curing room through the steam outlet 13 to rehumidify the tobacco leaves.

[0031] Of course, the present invention is not limited to the above-described implementations. Several other implementations based on the design concept of the present invention are provided below.

[0032] For example, in other embodiments, different from the above-described embodiments, Figure 1 As shown, a first filter 82 is provided on the water inlet pipe 8 near the water reservoir 9, and a second filter 75 is provided on the connecting pipe 7 between the third switch valve 74 and the second water pump 72. Both the first filter 82 and the second filter 75 can be filters commonly used by those skilled in the art.

[0033] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model fall within the protection scope of the present utility model.
