The smoke pump 310 can recover the hot air generated during baking and draw it into the interior of the serpentine coil 305 to heat the heat-conducting plate and then preheat the material inside the storage cylinder 3, thereby improving its baking efficiency.
[0022] In this utility model, the top of the storage cylinder 3 is connected to a communicating inlet 307, and the top of the inlet 307 is provided with a sealing cover 308.
[0023] In this utility model, the bottom four corners of the storage cylinder 3 are fixed with support legs 303, and the bottom of the support legs 303 is fixedly connected to the top of the base 1.
[0024] In this utility model, the exhaust end of the baking oven body 2 is connected to a communicating exhaust pipe 203, and the other end of the connecting pipe 301 is connected to and communicates with the outer wall of the exhaust pipe 203. A solenoid valve is installed inside the exhaust pipe 203, and a one-way valve 302 is installed inside the connecting pipe 301.
[0025] In this invention, the outer wall of the baking oven body 2 is provided with an observation window 201, and the top side of the baking oven body 2 is provided with a control panel 202.
[0026] In this utility model, a mounting cylinder 4 is provided at one end of the top of the base 1, and the mounting cylinder 4 is installed at an inclination. A rotating rod 403 is rotatably connected to one end of the inner wall of the mounting cylinder 4, and an auger 404 is fixed to the outer wall of the rotating rod 403. The discharge end of the mounting cylinder 4 is connected to and communicates with the feed end of the baking oven body 2. A motor 402 is installed at the other end of the mounting cylinder 4, and the output shaft of the motor 402 is fixedly connected to one end of the rotating rod 403. A feeding pipe 306 is connected to the bottom of the storage cylinder 3, and the other end of the feeding pipe 306 is connected to and communicates with the outer wall of the mounting cylinder 4. The auger 404 can convey materials, and a control valve is installed inside the feeding pipe 306.
[0027] In this utility model, two support plates 405 are fixed to the bottom of the outer wall of the mounting cylinder 4. The bottom of the two support plates 405 is fixed to the top of the base 1.

[0028] Working principle: In use, first open the sealing cover 308, then feed the material to be baked into the storage cylinder 3 through the feed inlet 307. Next, open the control valve in the feeding pipe 306 to transport the material into the mounting cylinder 4. Then, run the motor 402, which drives the rotating rod 403 to rotate, and in turn drives the auger 404 to rotate. The auger 404 then transports the material to the feeding end of the baking oven 2. The controller then controls the heating system inside the baking oven 2 to operate and bake the biomass. During the baking process, a large amount of hot air is generated, and after a period of operation, the hot air needs to be discharged through the exhaust pipe 203. During exhaust, the smoke extraction pump 310 is activated, which extracts air from the serpentine coil 305 and, through the connecting pipe 301, extracts the flue gas inside the exhaust pipe 203. The flue gas is then delivered into the serpentine coil 305. The smoke extraction pump 310 is then turned off, and the control valve in the gas delivery pipe is closed, allowing the flue gas to remain inside the serpentine coil 305. The outer wall of the serpentine coil 305 is then heated, and the heat-conducting plate transfers the heat from the serpentine coil 305 to the inside of the storage cylinder 3, preheating the material inside the storage cylinder 3. This preheating of the biomass improves its subsequent baking efficiency and enables the utilization of the flue gas, achieving high efficiency and energy saving.
