[0028] like Figure 4 As shown, this utility model provides a circulating dehumidifier technical solution for tobacco processing: the rotary dehumidification mechanism 8 includes a rotary motor 81, a rotating rod 82, a sealing cover plate 83, a connecting rod 84, and several tobacco leaf holders 85. The output shaft of the rotary motor 81 is fixedly connected to the top of the rotating rod 82, the central axis of the sealing cover plate 83 is rotatably connected to the middle of the outer wall of the rotating rod 82, the lower end of the outer wall of the rotating rod 82 is fixedly connected to the upper end of the connecting rod 84, and one end of each of the several tobacco leaf holders 85 is respectively ring-shaped. The array is set on the outer wall of the connecting rod 84. The output shaft of the rotary motor 81 drives the connecting rod 84 to rotate through the rotating rod 82, so that the tobacco leaf holder 85 moves in a circular motion inside the dehumidification cylinder 2, further improving the dehumidification efficiency of the tobacco leaves. The rotary motor 81 is externally fixed to the top of the mounting plate 7, and the output shaft of the rotary motor 81 extends through to the bottom of the mounting plate 7. The bottom of the sealing cover 83 overlaps the top of the dehumidification cylinder 2, and the sealing cover 83 covers the dehumidification cylinder 2 to reduce heat loss.

[0029] like Figure 5As shown, this utility model provides a circulating dehumidifier technical solution for tobacco processing: the tobacco storage component 85 includes a fixed frame 851, a mounting frame 852, a storage box 853, two breathable nets 854, four bolts 855, and four knobs 856. One end of the outer wall of the storage box 853 is fixedly connected to the inner wall of the mounting frame 852. The front and rear ends of the storage box 853 are respectively provided with through-hole mounting openings 8530. The outer walls of the two breathable nets 854 are respectively fixedly connected to the inner walls of the two mounting openings 8530. Tobacco leaves are placed inside the storage box 853, and hot air can dry the surface of the tobacco leaves by passing through the breathable nets 854. The outer wall of the storage box 853 is engaged with the inner wall of the fixed frame 851. One end of 55 is fixedly connected to the middle of the knob 856, and one end of the fixing frame 851 is fixedly connected to the outer wall of the connecting rod 84.

The outer wall of the bolt 855 passes through the insertion hole 8520 and is threaded to the inner wall of the threaded hole 8510. The storage box 853 is put into the fixing frame 851 to connect the mounting frame 852 and the fixing frame 851.

[0030] The working principle of this circulating dehumidifier used for tobacco processing will be explained in detail below.

[0031] like Figure 1-5As shown, during the tobacco processing, tobacco leaves are placed into multiple storage boxes 853 in sequence. Then, the storage boxes 853 are inserted into the fixed frame 851 via the mounting frame 852. Bolts 855 are then inserted into the threaded holes 8510 along the insertion holes 8520 to fix the storage boxes 853. Next, the hydraulic cylinder 9 is activated to retract. The output end of the hydraulic cylinder 9 drives the mounting plate 7 downwards along the moving groove 601 via the sliding plate 10, causing the reinforcing plate 12 to slide downwards along the outer wall of the supporting upright plate 11, thus covering the dehumidifying cylinder 2 with the sealing cover 83. Then, the heating rod 32 is activated to heat the tobacco leaves, and the temperature controller 4 is used to adjust the temperature of the heating rod 32. The fan 51 is then activated, and the fan 51... The exhaust pipe 53 draws hot air from the heating box 3 into the air box 54 through the connecting pipe 52, and then through multiple branch pipes 55 into the annular pipe 201, so that the hot air is sprayed out from the exhaust pipe 202. Combined with the start of the rotary motor 81, the connecting rod 84 is rotated through the rotating rod 82, which causes the tobacco leaf holder 85 to move in a circular motion in the dehumidification cylinder 2. The sprayed hot air passes through the breathable net 854 to dry the surface of the tobacco leaves, promotes uniform heating of the tobacco leaf surface, and achieves an effective dehumidification effect. During the dehumidification process, due to the continuous delivery of hot air, the hot air returns to the heating box 3 through the circulation pipe 203. By recycling the heat, energy loss is reduced, the utilization rate of heat energy is improved, and energy consumption is effectively reduced.

[0032] The specific types and structures of the hydraulic cylinder 9, heating rod 32, temperature controller 4, fan 51 and rotary motor 81 used are all existing products, and the specific circuit connection structure and control relationship are also existing technologies, which will not be elaborated on here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
