[0002] A series of complex physiological and biochemical changes, including macromolecular substance degradation process and flavor substance formation process, occur in tobacco during the curing process. During the curing process of tobacco, some volatile flavor substances formed will be released into the curing barn environment and combined with water vapor formed by dehydration in the curing process. These components will be lost to the air outside the curing barn during the curing barn dehumidification process, resulting in not only heat loss but also loss of flavor substances. Therefore, how to recover volatile flavor substances during the curing process of tobacco and apply them to cigarettes and other products to further increase the income of tobacco farmers is a problem that needs to be solved.

[0020] By those skilled in the art, the parts in the case are connected in sequence, and the specific connection and operation sequence should be referred to the following working principle, and the detailed connection means is the known technology in the art, and the following mainly introduces the working principle and process.

[0021] The traditional flavor substance recovery device cannot directly extract the aroma components in the tobacco curing barn, and first needs to condense the hot steam carrying the aroma components in the curing barn exhaust process, and then needs to collect the condensed water and then introduce the condensed water into the machine through a pump for extraction centrifugation. This operation increases the process of extracting the effective components of the aroma components in the extraction curing barn condensate, and increases the loss of volatile components in the condensate.

[0024] In the specific implementation process, it is worth pointing out that the pagoda two-way pipe 12 is provided with a valve for controlling the flow direction of the medium, the staff should connect the external driving device with the rotating rod 3, and then the rotating rod 3 can be driven to rotate by the external driving device, so as to drive the rotating drum 2 and the centrifugal shaft 23 to rotate, which can be driven by a motor, or other driving modes can be adopted, and the specific driving device is not limited, as long as it meets the use requirement, the external smoke can enter the inside of the inner pipe 17 through the smoke inlet pipe 20, and the spiral coil pipe 21 can condense and liquefy the water vapor in the inner pipe 17;

[0025] Further, the bottom of the cover plate 4 is fixedly connected with the centrifugal shaft 23, the outer wall of the centrifugal shaft 23 is sleeved with a flow blocking disc 24 from below, the bottom of the cover plate 4 is fixedly connected with a light phase weir plate 5 which is fixedly connected with the upper inner wall of the rotating drum 2, and the top of the rotating drum 2 is fixedly connected with a heavy phase weir plate 6;

[0026] In the specific implementation process, it is worth pointing out that the mixed phase in the rotating drum 2 is separated into light phase and heavy phase under the stirring of the centrifugal shaft 23 and through the light phase weir plate 5 and the heavy phase weir plate 6;

[0029] Further, the spiral coil 21 is connected with a compressor 22 at both ends, and the outer wall of the inner tube 17 is fixedly connected with a sleeve 18.

[0030] In the specific implementation process, it is worth pointing out that the compressor 22 can cool and circulate the cooling liquid in the spiral coil 21, thereby ensuring the condensation quality of the water vapor. In actual operation, the spiral coil 21 should be used in cooperation with a circulating pump, so that the circulation of the cooling water can be realized through the circulating pump.

The specific material is not limited, as long as it meets the use requirements.

[0033] Specifically, when using the device for extracting aroma components in the drying room, external flue gas enters the inner tube 17 through the flue gas inlet pipe 20. At this time, the spiral coil 21 can be used to condense and liquefy the water vapor. Simultaneously, the compressor 22 is turned on to ensure the liquefaction quality of the water vapor. Then, the liquefied water enters the interior of the shell 1 through the heavy phase inlet 11. Then, the external drive device connected to the rotating rod 3 is turned on. The external drive device can then drive the rotating rod 3 to rotate, thereby driving the rotating drum 2 and the centrifugal shaft 23 to rotate. Then, the pump body 14 is turned on, and the pump body 14 injects the extractant inside the extractant sealed bottle 13 into the interior of the shell 1 through the light phase inlet 9. Then, the extraction work can begin. The separated light phase and heavy phase media can be discharged through the light phase outlet 10 and the heavy phase outlet 8, respectively. Then, the operator adjusts the valve direction of the pagoda two-way pipe 12 so that the separated light phase re-enters the interior of the shell 1 through the light phase inlet 9, realizing the process of full-sealed and cyclic extraction of the extractant to achieve the maximum extraction volume.

[0034] Example 2, by Figure 1 and 2 It can be seen that a connecting cylinder 27 is threadedly connected to the lower outer wall of the housing 1, and a base 26 is rotatably connected to the lower outer wall of the connecting cylinder 27 via a bearing. The inner wall of the base 26 is rotatably connected to the lower part of the baffle plate 24 via a sealed bearing. A limit rod 28 is inserted into the bottom of the housing 1, and the bottom of the limit rod 28 is fixedly connected to the top of the base 26.

[0035] In the specific implementation process, it is worth noting that the outer wall of the connecting cylinder 27 is provided with a handle, which makes it easier for the staff to use the handle to drive the connecting cylinder 27 to rotate, thereby realizing the quick disassembly of the housing 1. The bottom of the housing 1 should be provided with a sealing gasket, so as to ensure the sealing performance between the housing 1 and the base 26, thereby avoiding leakage. The specific material of the sealing gasket is not limited, as long as it meets the usage requirements. The limit rod 28 can limit the housing 1, so that it can only achieve simple up and down movement.

[0036] Specifically, based on the above embodiment 1, when it is necessary to clean the inside of the housing 1, the operator twists the connecting cylinder 27. At this time, the connecting cylinder 27 rotates, and the housing 1 can move along the outer wall of the limiting rod 28. When the housing 1 leaves the inner wall of the connecting cylinder 27, the inside of the housing 1 can be cleaned.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
