The hot air entering the pipeline 84 finally enters the frying mechanism 1 to heat and fry the melon seeds and promote the discharge of dust.

[0028] A mixing pipe 35 and a burner 37 are provided between the biomass furnace 31 and the air conditioning chamber 36. The biomass furnace 31 and the air conditioning chamber 36 are connected through the mixing pipe 35 and the burner 37. A pipe six 311 is installed through the air conditioning chamber 36. The heating mechanism 3 also includes a fan 2 310. The pipe six 311 is connected to the air inlet of the fan 2 310. The frying mechanism 1 includes a wok body 11. The wok body 11 is provided with a pipe one 16. A pipe seven 314 is connected between the pipe one 16 and the air outlet of the fan 2 310.

[0029] A fifth pipe 38 connected to the gas mixing pipe 35 is fixedly installed on the air conditioning chamber 36, a second thermometer 312 and a second valve 313 are provided on the sixth pipe 311, and a second upper hopper 32, an incomplete combustion zone 33 and an ash hopper 34 are provided on the biomass furnace 31.

[0030] A heat exchanger 29 is provided inside the heat exchanger 23. An air inlet pipe 1 26, an air outlet pipe 2 28 and an air outlet pipe 3 210 are provided on the heat exchanger 29. The air inlet pipe 1 26 and the air outlet pipe 2 28 both extend to the outside of the heat exchanger 23. The air outlet pipe 3 210 is located inside the heat exchanger 23. The heat exchanger 23 is provided with an air outlet pipe 4 211, an air outlet pipe 5 212 and an air inlet pipe 2 213. The air outlet pipe 4 211 is connected to the air inlet pipe 3 39, the air outlet pipe 5 212 is connected to the pipe 5 38, and a valve 1 214 is provided inside the air outlet pipe 3 210.

[0031] The heat exchange mechanism 2 also includes a fan 22, an air outlet pipe 111 is provided on the frying pan body 11, a pipe 24 is connected between the air inlet of the dust collector 21 and the air outlet pipe 111, a pipe 3 25 is connected between the air inlet of the fan 22 and the air outlet of the dust collector 21, and a pipe 4 27 is connected between the air outlet of the fan 22 and the air inlet pipe 1 26.

[0032] A plurality of stir-frying chambers 13 are provided in the wok body 11. The top of the stir-frying chamber 13 is opened, and the bottom of the stir-frying chamber 13 is provided with a mesh plate 18. A heating tube 17 is provided below the mesh plate 18. The plurality of heating tubes 17 are interconnected and connected to the pipe 16. An adjustment plate 14 that can move up and down is provided between two adjacent stir-frying chambers 13.

[0033] Furthermore, the heating pipe 17 is used to spray the hot air flow input by the pipe 16 upward and pass through the mesh plate 18 to act on the melon seeds.

[0034] The plurality of stir-fry chambers 13 are stepped, and the mesh plates 18 are inclined.

[0035] An upper hopper 12 is installed on the wok body 11, and the upper hopper 12 is connected to the stir-fry chamber 13 located at the top. A level meter 15 is installed in the wok body 11, and the level meter 15 is located directly below the upper hopper 12. A lower hopper 110 is provided on one side of the stir-fry chamber 13 located at the bottom. A thermometer 112 and an inspection port 19 are provided on the side of the wok body 11 away from the pipe 16.

[0036] Furthermore, when the fan 22 is working, a negative pressure can be formed in the pipe 3 25. At this time, the air outlet pipe 111 is also in a negative pressure state, and the dust rising in the stir-fry chamber 13 can actively enter the air outlet pipe 111 and be discharged.

[0037] Furthermore, the opening degree of valve 1 214 can change the amount of hot air discharged from air outlet 3 210 , and ultimately change the temperature of air entering air outlet 4 211 and air outlet 5 212 .

[0038] Furthermore, by adjusting the height of the plate 14, the gap between the plate 14 and the mesh plate 18 below can be adjusted. Figure 3As shown, when the gap between the adjustment plate 14 and the mesh plate 18 increases, the speed at which the material in the stir-frying chamber 13 on the left side of the adjustment plate 14 enters the stir-frying chamber 13 on the right side will become faster, so that the time the material stays in the stir-frying chamber 13 for stir-frying becomes shorter;

[0039] like Figure 3 As shown, when the gap between the adjustment plate 14 and the mesh plate 18 increases or decreases, the speed at which the material in the stir-frying chamber 13 on the left side of the adjustment plate 14 enters the stir-frying chamber 13 on the right side will slow down, making the time the material stays in the stir-frying chamber 13 for stir-frying longer. Therefore, by adjusting the position height of the adjustment plate 14, the discharge speed of the material in the stir-frying chamber 13 can be adjusted.

[0040] In this embodiment, the biomass fuel falls into the biomass furnace 31 through the upper hopper 32, and the biomass fuel undergoes incomplete combustion in the incomplete combustion zone 33 to generate combustible gas. The combustible gas enters the burner 37 through the gas mixing pipe 35 and is burned. The flame generated by the combustion enters the air conditioning chamber 36.

[0041] The hot air flow generated by the flame heat passes through the pipe 6 311, the fan 2 310, the pipe 7 314 and the pipe 1 16 in sequence and enters the multiple heating pipes 17. After entering the heating pipes 17, the hot air flow will be ejected upward, and the melon seeds will be dropped from the upper hopper 12 into the stir-frying chamber 13 at the highest point. The materials at the highest point will roll downward from the top along the inclined multiple mesh plates 18 and finally be discharged through the lower hopper 110. During this process, the melon seeds will be heated and stir-fried by the hot air flow from bottom to top as they pass through the mesh plates 18, and the dust generated during the stir-frying process will rise and enter the air outlet pipe 111.

[0042] After roasting the melon seeds, the hot air flow will carry dust into the air outlet pipe 111 and enter the dust collector 21 through the second pipe 24. After the dust is removed by the dust collector 21, the clean hot air flow will flow through the third pipe 25, pass through the fan 1 22 and the fourth pipe 27, and enter the heat exchanger 29 through the air inlet pipe 1 26. The clean hot air flow entering the heat exchanger 29 will eventually be discharged to the outside of the equipment through the second air outlet pipe 28, and the remaining clean hot air flow will enter the heat exchanger 23.

[0043] The external cold air enters through the air inlet pipe 213 and contacts the surface of the heat exchanger 29. It will gradually heat up to form hot air and mix with the hot air flow discharged from the air outlet pipe 310. A part of the hot air + hot air flow mixture is discharged through the air outlet pipe 5 212 and enters the mixing pipe 35 through the pipe 5 38 to mix with the combustible gas in the mixing pipe 35, which plays an auxiliary role in the combustion of the combustible gas. The remaining part of the hot air + hot air flow mixture will enter the air conditioning chamber 36 through the air outlet pipe 4 211 and the air inlet pipe 39 to adjust the temperature of the flame heat discharged by the burner 37, so that it forms a hot air flow suitable for frying melon seeds.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
