Specifically, the smoke exhaust mechanism 3 recovers the discharged heat energy for reuse, thereby making the utilization efficiency of heat energy high.

[0032] See also Figure 1 , Figure 2 The drying mechanism 2 includes a heating box 201, and the heating box 201 is fixedly installed on the upper end of the base 1 near the fixed frame 101. There is a combustion chamber 202 for burning gas inside the heating box 201. The above-mentioned combustion chamber 202 is a prior art and will not be described in detail here. The gas is burned in the combustion chamber 202 to generate heat energy. An exhaust hood 203 is fixedly installed on the upper end of the combustion chamber 202. A heat transfer pipe 204 for transferring hot smoke is fixedly installed on the upper end of the exhaust hood 203. Hot smoke is generated after the gas burns. The hot smoke is collected by the exhaust hood 203 and then transferred to the drying cylinder 102 through the heat transfer pipe 204, so that the hot smoke dries the food in the drying box.

[0033] See also Figure 1 to Figure 3 A driving motor 205 is fixedly installed on the right end of the drying cylinder 102, and a stirring rod 206 is fixedly installed on the output end of the driving motor 205. A stirring piece 207 is fixedly installed on the outer wall of the stirring rod 206. Specifically, after placing the food in the drying cylinder 102, the driving motor 205 is started, so that the stirring rod 206 drives the stirring piece 207 to start rotating, and the food in the drying box is stirred, so that the food in the drying box is dried more evenly. A drying joint 208 is fixedly installed on one end of the stirring rod 206, and the end of the heat transfer pipe 204 away from the exhaust hood 203 is rotatably connected to the end of the drying joint 208 away from the drying cylinder 102. Specifically, the drying joint 208 allows the stirring rod 206 to maintain ventilation connection with the heat transfer pipe 204 during the rotation process.

[0034] See also Figure 1 to Figure 6A vent pipe 209 is fixedly installed at one end of the drying joint 208 away from the heat transfer pipe 204, and the vent pipe 209 passes through the interior of the stirring rod 206. A control valve 210 is fixedly installed at one end of the vent pipe 209 away from the drying joint 208. A control rod 211 is rotatably installed at the control end of the control valve 210, and a winding spring is provided at the connection between the control valve 210 and the control rod 211. Specifically, when the control rod 211 is not pulled, the control valve 210 is closed. When the control rod 211 is pulled, the rotation angle of the control rod 211 is increased. The larger the opening of the control valve 210 is, the larger the air transfer pipe 218 is fixedly installed at the end of the control valve 210 away from the ventilation pipe 209, and the end of the air transfer pipe 218 away from the control valve 210 is fixedly installed with a drying plate 212, and a plurality of drying holes 217 are opened on the inner wall of the drying plate 212, and the drying holes 217 are each provided with a protective net (not shown in the figure), the protective net prevents the food in the drying box from entering the drying holes 217 during the stirring process, causing the drying holes 217 to be blocked and the hot smoke cannot be discharged, and the drying plates 212 are symmetrically installed at both ends of the stirring blade 207.

[0035] See also Figure 1 to Figure 6 , a sliding groove 213 is provided at one end of the stirring piece 207 away from the stirring rod 206, and a resistance plate 214 is slidably installed in the sliding groove 213, and the resistance plate 214 is set to a trapezoid. The resistance plate 214 is set to a trapezoid, so that when the resistance plate 214 rotates to stir the food, the more water there is in the food, the greater the resistance the resistance plate 214 encounters. A control spring 215 is fixedly installed between the resistance plate 214 and the stirring piece 207, and a control line 216 is fixedly installed at one end of the resistance plate 214 close to the control spring 215, and the end of the control line 216 away from the resistance plate 214 is fixedly connected to the outer wall of the control rod 211. Specifically, when the resistance plate 214 is stirring the food, the resistance plate 214 moves, and the resistance plate 214 drives the control line 216 to move, so that the control line 216 pulls the control rod 211 to rotate, and the control valve 210 is opened. When the resistance plate 214 does not enter or leave the food, the control spring 215 pulls the resistance plate 214 to rebound to its original position.

[0036] See also Figures 1 to 8The smoke exhaust mechanism 3 includes a smoke exhaust pipe 301, and the smoke exhaust pipe 301 is fixedly installed at the upper end of the drying cylinder 102. An exhaust pump 302 is fixedly installed on the upper end of the smoke exhaust pipe 301, and an exhaust pipe 303 at the output end of the exhaust pump 302 is fixedly installed. A heating plate 304 is fixedly installed at the upper end of the drying cylinder 102 near the exhaust pipe 303. Specifically, the heat in the hot steam is transferred to the heating plate 304, and the heating plate 304 is arranged at the upper end of the drying cylinder 102 to prevent the water vapor dried in the drying cylinder 102 from condensing into water at the upper end of the inner wall of the drying cylinder 102, and the exhaust pipe 303 is bent and folded inside the heating plate 304, and the exhaust A thermal insulation plate 305 is provided at the lower end of the tube 303, and the thermal insulation plate 305 prevents the cooled condensed water in the exhaust pipe 303 from cooling the heating plate 304. A collecting box 306 is provided at the end of the exhaust pipe 303 away from the exhaust pump 302, and the collecting box 306 is fixedly installed at the upper end of the fixing frame 101. An exhaust groove 307 is provided at the upper end of the collecting box 306. Specifically, when the drying device is used, the exhaust pump 302 is started, so that the exhaust pump 302 transfers the evaporated water vapor in the drying cylinder 102 through the exhaust pipe 303 to the collecting box 306 to cool and collect the water vapor, and the waste smoke is discharged through the exhaust groove 307.

[0037] The working principle of the present invention is as follows: when food needs to be dried, the display is placed in the drying cylinder 102, the combustion chamber 202 is ignited, and the hot smoke from the combustion chamber 202 is transferred to the ventilation pipe 209 through the heat transfer pipe 204, and then discharged through the drying plate 212 to dry the food in the drying cylinder 102, and the driving motor 205 is started, and the stirring rod 206 starts to drive the drying plate 212 to start rotating to stir the food in the drying cylinder 102, so that the food is dried more evenly;

[0038] When the stirring rod 206 stirs the food in the drying drum 102, the undried part of the food in the drying drum 102 has a large amount of moisture, which causes the resistance plate 214 to be subjected to increased force, so that the resistance plate 214 pulls the control line 216 to move, and the control line 216 pulls the control rod 211, so that the opening of the control valve 210 increases, and the discharge of hot smoke from the undried part increases, thereby improving the drying efficiency of uniformly drying the food.
