[0002] Bitter melon contains a lot of vitamin C, so it is necessary to use extraction equipment to extract the vitamin C from the bitter melon, and during the extraction process, a constant temperature heating device is needed to heat the bitter melon.

[0003] The constant temperature heating device in the prior art generally heats a high-speed air flow through a heating tube to form a hot air flow, and then heats the heating tube through the hot air flow to heat the bitter melon in the heating tube. Since the heating tube is in direct contact with the air flow, the heat of the heating tube can be quickly transferred to the air flow, resulting in that when the heating tube is rapidly heated, the temperature of the hot air flow can rise rapidly, causing the temperature of the hot air flow to fluctuate too much, and when the fan speed increases, the flow rate of the hot air flow increases, causing the heating temperature to rise. Changes in the fan speed and the temperature of the hot air flow will affect the heating temperature, resulting in the inability to stabilize the heating temperature of the heating tube and the inability to heat the heating tube at a constant temperature. There are problems such as inconvenience in adjusting the heating temperature and the heating temperature not being high enough. Therefore, it is necessary to provide a constant temperature heating device for extracting vitamin C from bitter melon. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1 to 9A constant temperature heating device for extracting vitamin C from bitter melon comprises a mounting plate 1 and a heating box 2 and a plurality of support columns 3 fixed on the top thereof, a heating box 4 with an open top fixed on the top of the plurality of support columns 3, a conveying box 5 fixed to the bottom of the heating box 4 and one end of the heating box 2, a plurality of reflux cylinders 10 fixed to the side of the heating box 4 and the top of the heating box 2, a sealing plate 6 for sealing the heating box 4 is fixed on the top, a heating cylinder 7 is fixed through the middle of the sealing plate 6, a motor plate 8 for sealing the heating box 2 is fixed to the other end of the heating box 2, an AC motor 9 is fixed to the side of the motor plate 8 through a support rod, a fixed bearing 11 is fixed through the middle of the motor plate 8, and a rotating shaft fixed to the power output end of the AC motor 9 is fixed through the middle of the fixed bearing 11 12. A disc plate 13 is fixed at one end of the rotating shaft 12, and a rotating cylinder 14 is nested on the disc plate 13. A sealing ring 17 and an intermediate plate 16 are fixed at one end and the middle of the rotating cylinder 14 respectively. A sealed bearing 18 is fixed through the middle of the sealing ring 17 and the intermediate plate 16. An output cylinder 19 and an input cylinder 20 are fixed through the middle of the two sealed bearings 18 respectively. An elbow pipe 21 is embedded in one side of the output cylinder 19, and a heating mechanism is fixed at the ends of the elbow pipe 21 and the input cylinder 20; a plurality of heat-conducting fan blades 15 are fixed to the periphery of the rotating cylinder 14, and the plurality of heat-conducting fan blades 15 are tilted and fixed on the surface of the rotating cylinder 14, so that an airflow is formed when the rotating cylinder 14 and the plurality of heat-conducting fan blades 15 are synchronized, and a hot air channel 31 is formed in the middle of the heat-conducting fan blades 15.

[0030] Preferably, a plurality of communication holes 30 are formed in the rotating cylinder 14, and the plurality of communication holes 30 are respectively located on both sides of the middle plate 16. The plurality of communication holes 30 are connected to the hot air channel 31 inside the heat-conducting blade 15. A groove is formed on one side of the heat-conducting blade 15. The two heat-conducting blades 15 are riveted together to form the hot air channel 31 through the two grooves.

[0031] When implemented, the grooves of the two heat-conducting fan blades 15 form a hot air channel 31, and the hot air flow flows in the hot air channel 31 inside the heat-conducting fan blades 15. The hot air flow heats the heat-conducting fan blades 15 so that their temperature rises rapidly. Then, the heat-conducting fan blades 15 form an airflow at high speed while quickly transferring heat to the air, so that the heat-conducting fan blades 15 directly form a hot air flow at high speed. Since the force of the high-speed air flow is generated by the heat-conducting fan blades 15, the air will rub against the heat-conducting fan blades 15 at high speed when forming the airflow. Since the heat of the heat-conducting fan blades 15 can be evenly transferred to a large amount of air, when the temperature of the hot air flow changes, the influence of the hot air flow on the temperature of the hot air flow formed by the heat-conducting fan blades 15 can be reduced.

[0032] Preferably, the middle plate 16 is located in the middle of the rotating cylinder 14, so that the space inside the rotating cylinder 14 is divided equally by the middle plate 16. One end of the output cylinder 19 and the input cylinder 20 is provided with a vertical bend. The output cylinder 19 and the input cylinder 20 are nested with each other, and the top of the input cylinder 20 passes through the top of the output cylinder 19. The tops of the output cylinder 19 and the input cylinder 20 pass through the top of the heating box 2.

[0033] During specific implementation, the input cylinder 20 injects the hot air flow into the rotating cylinder 14, and then the hot air flow enters the hot air channel 31 of the heat-conducting fan blade 15 through the connecting hole 30, and the hot air flow returns to the interior of the rotating cylinder 14 through the connecting hole 30, and the hot air flow is transported out of the rotating cylinder 14 through the output cylinder 19. The hot air flow is separated by the intermediate plate 16 when entering and discharging the rotating cylinder 14, so that the hot air flow circulates inside the hot air channel 31 of the heat-conducting fan blade 15, which can greatly increase the contact time between the hot air flow and the heat-conducting fan blade 15, so that the heat of the hot air flow is fully transferred to the heat-conducting fan blade 15.

[0034] Preferably, both ends of the rotating cylinder 14 are open, one end of the rotating cylinder 14 is sealed by a disc plate 13, and the other end of the rotating cylinder 14 is sealed by a sealing ring 17. The bottom of the heating cylinder 7 extends into the interior of the heating box 4. The interiors of the heating box 2, the heating box 4 and the conveying box 5 are connected. A plurality of heat-conducting fan blades 15 surround the outer periphery of the rotating cylinder 14.

[0035] During specific implementation, the heat-conducting fan blades 15 form an airflow at high speed and simultaneously transfer heat to the air rapidly, so that the heat-conducting fan blades 15 directly form a hot airflow at high speed. When the rotation speed of the heat-conducting fan blades 15 is faster, the friction speed of the heat-conducting fan blades 15 and the air is also faster, and the flow rate of the hot air flow generated by the heat-conducting fan blades 15 is also higher, resulting in the temperature of the hot air flow formed by the heat-conducting fan blades 15 not being proportional to its rotation speed, which can reduce the influence of the rotation speed of the heat-conducting fan blades 15 on the temperature of the hot air flow formed by it.

[0036] Preferably, the heating mechanism is a heat exchange device, and the ends of the elbow pipe 21 and the input tube 20 are respectively connected to the heat exchange device. The heat exchange device can be purchased on the market or customized. The heat exchange device generates a heat-conducting fluid, which is input through the input tube 20, so that the heat-conducting fluid flows through the hot air channel 31 of the heat-conducting fan blade 15. Finally, the heat-conducting fluid enters the elbow pipe 21 from the output tube 19, so that the heat-conducting fluid circulates through the heat exchange device and flows through the hot air channel 31 inside the heat-conducting fan blade 15. The heat exchange device heats the heat-conducting fan blade 15 through the heat-conducting fluid, wherein the heat-conducting fluid can be water vapor or automobile coolant, etc.

[0037] Preferably, the heating mechanism comprises a hot air cylinder 22, a fixed tube 23, a heating tube 24, a welding plate 25, a servo motor 26, a waterproof bearing 27, a transmission shaft 28 and a propeller 29. The end of the input tube 20 is nested with a hot air cylinder 22 with one end open, and a welding plate 25 for sealing the hot air cylinder 22 is fixed on the inner wall of one end thereof. A waterproof bearing 27 is fixed through the middle of the welding plate 25, and a transmission shaft 28 is fixed through the middle of the waterproof bearing 27. A servo motor 26 is fixed to one end of the transmission shaft 28, and a plurality of propellers 29 are fixed to the other end of the transmission shaft 28; a fixed tube 23 is fixed through the other end of the hot air cylinder 22, and a heating tube 24 is embedded in the middle of the fixed tube 23. One end of the elbow tube 21 is embedded in the side of the hot air cylinder 22, the servo motor 26 is fixed to the welding plate 25 by a support rod, and the heating tube 24 is inserted into the middle of the input tube 20 and nested with it.

[0038] When implementing it, as shown in the attached instructions Figures 3 to 7 As shown, the servo motor 26 drives the transmission shaft 28 and the propeller 29 to rotate at high speed. The rotation of the propeller 29 forms an air flow that flows from top to bottom and enters the input cylinder 20. The heating tube 24 heats the air flow inside the input cylinder 20, so that the air flow temperature inside the input cylinder 20 rises rapidly. The hot air flow in the output cylinder 19 is re-delivered to the hot air cylinder 22 through the elbow tube 21, so that the hot air flow circulates inside the hot air cylinder 22, the rotating cylinder 14 and the heat-conducting fan blades 15.

[0039] Among them, the disc plate 13, the intermediate plate 16 and the sealing ring 17 are fixed to the inner wall of the rotating cylinder 14. The sealing ring 17 can rotate around the sealing bearing 18 at the end of the output cylinder 19, and the intermediate plate 16 can rotate around the sealing bearing 18 at the end of the input cylinder 20. One of the sealing bearings 18 ensures that the seal is maintained between the intermediate plate 16 and the input cylinder 20, and the other sealing bearing 18 ensures that the seal is maintained between the sealing ring 17 and the output cylinder 19.

[0040] In the present invention, when in use, first, put the bitter melon into the interior of the heating cylinder 7, the AC motor 9 drives the rotating shaft 12, the disc plate 13, the rotating cylinder 14, the heat-conducting fan blades 15, the intermediate plate 16 and the sealing ring 17 to rotate synchronously at a high speed, the heat-conducting fan blades 15 rotate to form an air flow inside the heating box 2, the air flow enters the conveying box 5, and then the air flow enters the heating box 4, the air flow heats the heating cylinder 7 to increase its temperature, and the bitter melon inside the heating cylinder 7 is heated inside it, as shown in the attached manual. Figures 3 to 7As shown, the servo motor 26 drives the transmission shaft 28 and the propeller 29 to rotate at a high speed. The rotation of the propeller 29 forms an air flow that flows from top to bottom and enters the input cylinder 20. The heating tube 24 heats the air flow inside the input cylinder 20, so that the air flow temperature inside the input cylinder 20 rises rapidly to form a hot air flow. The input cylinder 20 injects the hot air flow into the rotating cylinder 14, and then the hot air flow enters the hot air channel 31 of the heat-conducting fan blades 15 through the connecting hole 30. The hot air flow returns to the interior of the rotating cylinder 14 through the connecting hole 30, and the hot air flow is transported out of the rotating cylinder 14 through the output cylinder 19. The hot air flow is separated by the middle plate 16 when entering and discharging the rotating cylinder 14, and the hot air flow in the output cylinder 19 is re-transmitted to the hot air cylinder 22 through the elbow pipe 21, so that the hot air flow circulates inside the hot air cylinder 22, the rotating cylinder 14 and the heat-conducting fan blades 15. The heat of the heating tube 24 is transmitted to the heat-conducting fan blades 15 through the air flow, and the heat of the heat-conducting fan blades 15 is transmitted to the air flow.
