[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Combined with Figure 1-3A tobacco shred drying device comprises a control support box 1 and an insulated combustion and heating box 2. The top of the combustion and heating box 2 is connected with a hot air output pipe 7, which needs to be connected to the tobacco drying room, and the pipe can also be rebuilt as needed. The combustion and heating box 2 is provided with an ash collecting box 3, a combustion box 4, a feeding box 5 and a filter box 6 connected to the hot air output pipe 7, which are interconnected from bottom to top. The top of the control support box 1 is connected with a spiral feeding pipe 8 connected to the feeding box 5. The top of the spiral feeding pipe 8 is connected with a storage box 9. The fuel stored in the storage box 9 is preferably pellet fuel. The pellet fuel It is convenient to transport and resistant to burning, so as to ensure the convenience of use. A combustion support net 10 is connected in the middle of the combustion box 4.
