Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically a steaming and frying processing device for cottonseed oil processing. Background Technology

[0002] Currently, the conventional indirect heating structure of cottonseed oil processing steaming and roasting equipment mostly adopts a design of adding an annular sealed cover to the outside of the steaming and roasting pot. Heating steam is introduced into the sealed cavity formed by the annular cover and the outer wall of the pot, and the heat is conducted and diffused to the internal material through the metal cavity wall of the steaming and roasting pot, thereby achieving indirect heating of the material. This traditional heating method relies on a single radial heat conduction path through the cavity wall, which is limited in heat transfer mode and has low transfer efficiency. This not only results in a slow overall heating rate of the material, directly prolonging the steaming and roasting process time and increasing steam and power energy consumption, but also causes the temperature of the cavity wall area to be affected because the steam acts directly on the cavity wall. The temperature is significantly higher than that of the cottonseed cake, resulting in uneven temperature distribution. Since cottonseed cakes require a special process of high-moisture steaming, prolonged contact between the high-temperature chamber wall and the high-moisture cake easily leads to cake adhesion to the chamber wall, drying, and coking. This results in inconsistent steaming and roasting levels, affecting the stable removal of free gossypol, insufficient oil release, and fluctuations in residual oil content in the cake, thus reducing oil extraction efficiency and crude oil quality. Furthermore, cleaning the coking deposits is tedious and difficult, significantly increasing daily maintenance workload and downtime. Therefore, this invention provides a steaming and roasting processing device for cottonseed oil processing. Summary of the Invention

[0003] The purpose of this invention is to provide a steaming and frying processing device for cottonseed oil processing, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: a steaming and frying processing device for cottonseed oil processing, comprising several steaming and frying pans fixedly stacked from top to bottom, each steaming and frying pan having movable rings rotatably connected to its upper and lower ends, a main drive rod slidably arranged between the movable rings, a number of mounting shells fixedly installed on the main drive rod, and the mounting shells being located inside corresponding steaming and frying pans, each mounting shell having two symmetrical scrapers, a steam hood being provided on the outer ring surface of each steaming and frying pan, and a number of heat-conducting contacts being circumferentially fixedly installed at equal intervals on the inner ring surface of each steaming and frying pan, with the side of the heat-conducting contacts away from the corresponding steaming and frying pan extending into the steam hood, a heat-conducting ring being provided between each adjacent number of heat-conducting contacts, and a number of heat-conducting arc rods being provided on each heat-conducting ring. Heat dissipation fins are provided between several adjacent heat-conducting arc rods. This device conducts part of the heat from the steam hood to the center of the pot body through the heat dissipation fins in the inner cavity and the reciprocating piston plate, forming a two-way heat diffusion between the inner and outer walls. This can balance the heat, accelerate the heating, and prevent the material from sticking to the wall. This structure can directly modify existing equipment without increasing the power of the steam generator. With the heat-conducting rods to recover waste heat, the thermal energy utilization rate is greatly improved. The reciprocating mechanism synchronously drives the scraper to move in opposite directions and gently squeeze, so as to achieve uniform processing of the material, prevent shell and blank separation, ensure that the shell and kernel soften at the same time, and promote the pre-release of oil to improve the oil yield. At the same time, the reciprocating motion of the scraper can carry away the moisture accumulated at the bottom, inhibit the agglomeration of the material, and further optimize the heat utilization. This device reduces equipment modification costs and energy consumption, improves heating uniformity and material processing effect, and achieves high efficiency and cost reduction.

[0005] Preferably, a drive motor is fixedly installed on the top of the steaming and frying pot, and a drive gear is fixedly installed on the output end of the drive motor. A column ring is fixedly installed on the top of the steaming and frying pot, and a driven gear that meshes with the drive gear is rotatably connected to the top of the column ring. The driven gear and the main drive rod are slidably connected up and down. During the steaming and frying process, the drive motor drives the drive gear to rotate, and the drive gear drives the driven gear, the main drive rod, the mounting shell and the scraper to rotate. The scraper stirs the material in the steaming and frying pot, so that the material undergoes physical and chemical changes under precise control of temperature and moisture, thereby improving the oil yield of subsequent pressing and reducing the content of harmful substances such as gossypol.

[0006] Preferably, a crossbar is welded to the top of the main drive rod, and two symmetrical support frames are welded to the top of the steaming and frying pot located at the top. A corrugated ring frame that cooperates with the crossbar is welded between the tops of the two support frames.

[0007] Preferably, a C-shaped plate is fixedly installed in the inner cavity of each mounting shell, and a sliding rod is slidably provided at both ends of each C-shaped plate. Several scrapers are welded to the ends of the corresponding sliding rods respectively. A circular plate is welded to the side of each sliding rod away from the corresponding scraper. A spring is wound around the body of each sliding rod, and several springs are respectively connected between the corresponding C-shaped plate and the corresponding circular plate. A pressure plate is welded to the side wall of each circular plate.

[0008] Preferably, each of the mounting shells has a sliding pressure rod at its top, a horizontal plate welded to its bottom, and a spring wound around its body. Several springs are connected between the top of the inner cavity of the corresponding mounting shell and the corresponding horizontal plate. A V-shaped frame is welded to the bottom of each horizontal plate. The moving mounting shell will drive the pressure rod to move up and down synchronously. When the mounting shell moves upward, the mounting shell drives the pressure rod to move upward. The moving pressure rod moves into the mounting shell under the obstruction of the top cavity wall of the steaming pot. The moving pressure rod pushes the horizontal plate and the V-shaped frame to move. The moving V-shaped frame pushes the two symmetrical pressure plates to move. In addition, due to the structural characteristic of the V-shaped frame contracting towards the center, the two symmetrical pressure plates drive the corresponding sliding rod and the corresponding scraper to move, thereby causing the scrapers to move towards each other.

[0009] Preferably, each of the steaming and frying pots has a ventilation hood welded to the top of its inner cavity. Each ventilation hood has several one-way air inlet valves on its annular surface. Each heat dissipation fin has several springs circumferentially connected at equal intervals at its bottom. A piston plate is connected between the bottoms of each pair of adjacent springs. Each piston plate has several one-way air outlet valves circumferentially arranged at equal intervals at its bottom. Since the crossbar at the top of the main drive rod is slidably set within the wave-shaped ring frame, when the drive motor drives the crossbar to rotate, the crossbar will move up and down along the trajectory of the wave-shaped ring frame, thereby causing the main drive rod to drive the mounting shell and piston plate to move up and down. The heat-conducting contact can transfer part of the heat inside the steam hood to the heat-conducting ring, and then the heat-conducting ring will transfer the heat to the heat dissipation fins through the heat-conducting arc rod.

[0010] Preferably, each of the steaming and frying pots has a feed inlet at the top and a discharge outlet at the bottom. Each of the steam hood ring walls is connected to an indirect steam pipe, and each of the steaming and frying pot ring walls is connected to a direct steam pipe. The top of the steaming and frying pot is connected to two symmetrical exhaust pipes.

[0011] This invention provides an improved steaming and roasting processing device for cottonseed oil processing, which has the following improvements and advantages compared with the prior art: In summary, this device uses internal heat dissipation fins and a reciprocating piston plate to conduct some of the heat from the steam hood to the center of the pot, creating a two-way heat diffusion system with the external wall heat conduction. This evens out heat distribution, accelerates heating, and prevents the material from sticking to the wall. This structure allows for direct modification of existing equipment without increasing the power of the steam generator. Combined with a heat-conducting rod to recover waste heat, it significantly improves thermal energy utilization. The reciprocating mechanism synchronously drives the scrapers, moving them in opposite directions and applying slight pressure to ensure uniform material processing, prevent shell-material separation, ensure simultaneous softening of the shell and kernel, and promote pre-release of oil to increase oil yield. Simultaneously, the reciprocating motion of the scrapers removes accumulated moisture from the bottom layer, inhibiting material agglomeration and further optimizing heat utilization. This device reduces equipment modification costs and energy consumption while improving heating uniformity and material processing efficiency, achieving high efficiency and cost reduction.

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] This invention provides an improved steaming and roasting processing device for cottonseed oil processing. The technical solution of this invention is as follows: like Figures 1-11As shown, a steaming and frying processing device for cottonseed oil processing includes several steaming and frying pans 1 fixedly stacked from top to bottom. Each steaming and frying pan 1 has movable rings 2 rotatably connected to its upper and lower ends. A main drive rod 3 is slidably arranged between the movable rings 2. Several mounting shells 4 are fixedly installed on the main drive rod 3, and each mounting shell 4 is located inside a corresponding steaming and frying pan 1. Each mounting shell 4 contains two symmetrical scrapers 5. A steam hood 6 is provided on the outer ring surface of each steaming and frying pan 1. Several heat-conducting contacts 7 are circumferentially fixedly installed at equal intervals on the inner ring surface of each steaming and frying pan 1. The side of each heat-conducting contact 7 away from the corresponding steaming and frying pan 1 extends into the steam hood 6. A heat-conducting ring 8 is provided between each pair of adjacent heat-conducting contacts 7. Several heat-conducting arc rods 9 are provided on each heat-conducting ring 8. Heat dissipation fins 10 are provided between several adjacent heat-conducting arc rods 9. Each steaming and frying pot 1 has a feed inlet 32 ​​through the top and a discharge outlet 33 through the bottom. Each steam hood 6 has an indirect steam pipe 34 connected to its annular wall and a direct steam pipe 35 connected to its annular wall. The top of the steaming and frying pot 1 has two symmetrical exhaust pipes 36 connected to its top. In use, cottonseed kernel flakes after calcination are added into the first steaming and frying pot 1 through the feed inlet 32. Then, high-temperature steam is delivered into the steaming and frying pot 1 through the direct steam pipe 35 to heat and humidify the steaming and frying pot 1. At the same time, high-temperature steam is delivered into the steam hood 6 through the indirect steam pipe 34. The heat of this high-temperature steam is transferred to the material inside the steaming and frying pot 1 through the cavity wall. Furthermore, a drive motor 11 is fixedly installed on the top of the steaming and frying pot 1, and a drive gear 12 is fixedly installed on the output end of the drive motor 11. A column ring 13 is fixedly installed on the top of the steaming and frying pot 1, and a driven gear 14 that meshes with the drive gear 12 is rotatably connected to the top of the column ring 13. The driven gear 14 and the main drive rod 3 are slidably connected up and down. During the steaming and frying process, the drive motor 11 drives the drive gear 12 to rotate, and the drive gear 12 drives the driven gear 14, the main drive rod 3, the mounting shell 4 and the scraper 5 to rotate. The scraper 5 stirs up the material in the steaming and frying pot 1, so that the material undergoes physical and chemical changes under precise control of temperature and moisture, thereby increasing the oil yield of subsequent pressing and reducing the content of harmful substances such as gossypol.

[0016] Furthermore, a crossbar 15 is welded to the top of the main drive rod 3, and two symmetrical support frames 16 are welded to the top of the steaming pot 1 located at the top. A corrugated ring frame 17 that cooperates with the crossbar 15 is welded between the tops of the two support frames 16. A ventilation hood 27 is welded to the top of the inner cavity of each steaming pot 1. Several one-way air intake valves 28 are provided on the annular surface of each ventilation hood 27. Several springs 29 are circumferentially connected at equal intervals at the bottom of each heat dissipation fin 10. A piston plate 30 is connected between the bottoms of each pair of adjacent springs 29. The bottoms of each piston plate 30 are circumferentially connected at equal intervals. Several one-way vent valves 31 are arranged circumferentially. Since the crossbar 15 at the top of the main drive rod 3 is slidably positioned within the wave-shaped ring frame 17, when the drive motor 11 rotates the crossbar 15, the crossbar 15 moves up and down along the trajectory of the wave-shaped ring frame 17, thereby causing the main drive rod 3 to move the mounting shell 4 and piston plate 30 up and down. The heat-conducting contact 7 can transfer some of the heat from the vapor hood 6 to the heat-conducting ring 8, which then transfers the heat to the heat dissipation fins 10 via the heat-conducting arc rod 9. When the piston plate 30 moves downward, the space within the ventilation hood 27 expands. The gas inside the vent hood 27 enters through the one-way inlet valve 28. When the piston plate 30 moves upward, the space inside the vent hood 27 is compressed, and the gas inside is discharged through the one-way outlet valve 31. The discharged gas, carrying the heat from the heat dissipation fins 10, is blown towards the central area of ​​the steaming pot 1. This forms a circular diffusion of heat from the outside to the inside of the steaming pot 1 cavity wall, and a circular diffusion of heat from the inside to the outside of the heat dissipation fins 10. The two heat paths work together to achieve uniform heat diffusion and avoid heat accumulation that causes the material to stick to the wall. In addition, this device can be used in existing devices. The modification improves the heating rate of the existing device and reduces the upgrade cost without increasing the power of the indirect steam generator through dual-path collaborative operation. Specifically, the steam input from the direct steam pipe 35 moves upward through the outlet 33 and inlet 32 ​​between adjacent steaming pots 1 and is finally discharged through the exhaust pipe 36. The upward-flowing steam will pass over the heat-conducting arc rod 9, which can recover the heat of the steam that has not fully released its heat, thereby improving the steam heat utilization rate of the device to a certain extent. Furthermore, a C-shaped plate 18 is fixedly installed inside the cavity of each mounting shell 4. Each C-shaped plate 18 has sliding rods 19 slidably mounted at both ends. Several scrapers 5 are welded to the ends of corresponding sliding rods 19. A circular plate 20 is welded to the side of each sliding rod 19 away from the corresponding scraper 5. A spring 21 is wound around the body of each sliding rod 19, and several springs 21 are connected between the corresponding C-shaped plate 18 and the corresponding circular plate 20. A pressure plate 22 is welded to the side wall of each circular plate 20. A pressure rod 23 is slidably mounted on the top of each mounting shell 4. Each pressing rod 23 has a horizontal plate 24 welded to its bottom. A spring 25 is wound around the body of each pressing rod 23, and several springs 25 are connected between the top of the corresponding mounting shell 4 and the corresponding horizontal plate 24. A V-shaped frame 26 is welded to the bottom of each horizontal plate 24. The vertically moving mounting shell 4 will drive the pressing rod 23 to move synchronously up and down. When the mounting shell 4 moves upward, it drives the pressing rod 23 upward. The upward-moving pressing rod 23 moves into the mounting shell 4 under the obstruction of the top cavity wall of the steaming pot 1. The pressure bar 23 pushes the horizontal plate 24 and the V-shaped frame 26 to move. The moving V-shaped frame 26 pushes the two symmetrical lower pressure plates 22 to move. In addition, due to the structural characteristic of the V-shaped frame 26 contracting towards the center, the two symmetrical lower pressure plates 22 respectively drive the corresponding sliding rods 19 and the corresponding scrapers 5 to move, thereby causing the scrapers 5 to move towards each other. During this process, the scrapers 5 rotate and move up and down simultaneously. When they move upward, the two symmetrical scrapers 5 move towards each other synchronously. When the scrapers 5 are not moving upward, they push the lower material blank into the... As the material moves, the lower material is subjected to dual compression from the upper material and the pusher plate, causing the shell and kernel of the material to soften simultaneously, thus preventing shell-embryo separation. At the same time, the compression promotes the pre-release of oil from the cells, increasing the oil yield. When the scraper 5 moves upward and towards each other, the lower material between them is gradually replaced by the upper material. At this time, with the help of the two scrapers 5 moving towards each other, the upper material can also achieve simultaneous softening of the shell and kernel. This allows the material to undergo more comprehensive and uniform light compression, further improving the oil yield.

[0017] Working principle: During use, cottonseed kernel flakes after calcination are added into the first steaming and frying pot 1 through the feed inlet 32. Then, high-temperature steam is supplied into the steaming and frying pot 1 through the direct steam pipe 35, thereby heating and humidifying the steaming and frying pot 1. At the same time, high-temperature steam is supplied into the steam hood 6 through the indirect steam pipe 34. The heat of this high-temperature steam is transferred to the material inside the steaming and frying pot 1 through the cavity wall. During the steaming and frying process, the drive motor 11 drives the drive gear 12 to rotate. The drive gear 12 drives the driven gear 14, the main drive rod 3, the mounting shell 4 and the scraper 5 to rotate. With the help of the scraper 5, the material inside the steaming and frying pot 1 is turned and fried, so that the material undergoes physical and chemical changes under the precise control of temperature and moisture, thereby increasing the oil yield of subsequent pressing and reducing the content of harmful substances such as gossypol. Because the crossbar 15 at the top of the main drive rod 3 is slidably set within the wave-shaped ring frame 17, when the drive motor 11 drives the crossbar 15 to rotate, the crossbar 15 will move up and down along the trajectory of the wave-shaped ring frame 17, thereby causing the main drive rod 3 to drive the mounting shell 4 and piston plate 30 to move up and down. The heat-conducting contact 7 can transfer some of the heat inside the steam hood 6 to the heat-conducting ring 8, which then transfers the heat to the heat dissipation fins 10 via the heat-conducting arc rod 9. When the piston plate 30 moves down, the space inside the ventilation hood 27 expands, and the gas inside enters the ventilation hood 27 through the one-way inlet valve 28. When the piston plate 30 moves up, the space inside the ventilation hood 27 is compressed, and the gas inside is discharged through the one-way outlet valve 31. The discharged gas, carrying the heat from the heat dissipation fins 10, is blown towards the central area of ​​the steaming pot 1, thus forming a steam... The heat from the wall of the wok 1 cavity diffuses in a ring from the outside to the inside, while the heat from the heat dissipation fins 10 diffuses in a ring from the inside to the outside. These two heat paths work together to achieve uniform heat diffusion and prevent the material from sticking to the wall due to heat accumulation. In addition, this device can be modified on existing devices. Without increasing the power of the indirect steam generator, the heating rate of the existing device can be improved through the dual-path coordinated operation, reducing the upgrade cost of the existing device. The steam input from the direct steam pipe 35 moves upward from bottom to top through the outlet 33 and inlet 32 ​​between adjacent woks 1, and is finally discharged through the exhaust pipe 36. The upward-flowing steam will pass over the heat-conducting arc rod 9, which can recover the heat of the steam that has not been fully released, thus improving the steam heat utilization rate of this device to a certain extent. Furthermore, the vertically moving mounting shell 4 drives the downward pressure rod 23 to move synchronously up and down. When the mounting shell 4 moves upward, it drives the downward pressure rod 23 upward. The upward-moving downward pressure rod 23 moves into the mounting shell 4 under the obstruction of the top cavity wall of the inner cavity of the steaming pot 1. The moving downward pressure rod 23 pushes the horizontal plate 24 and the V-shaped frame 26 to move. The moving V-shaped frame 26 pushes the two symmetrical downward pressure plates 22 to move. In addition, due to the structural characteristic of the V-shaped frame 26 contracting towards the center, the two symmetrical downward pressure plates 22 respectively drive the corresponding sliding rod 19 and the corresponding scraper 5 to move, thereby causing the scraper 5 to move towards each other. During this process, the scraper 5 rotates and moves up and down reciprocally. When it moves upward, the two symmetrical scraper 5 move towards each other synchronously. When the scraper 5 does not move upward, It pushes the lower layer of material to move. At this time, due to the double compression of the upper layer of material and the pusher plate, the shell and kernel of the material soften simultaneously, thus preventing the shell and embryo from separating. At the same time, the compression promotes the pre-release of oil from the cells, increasing the oil yield. When the scraper 5 moves upward and moves towards each other, the lower layer of material between them is gradually replaced by the upper layer of material. At this time, with the help of the light compression applied by the two scrapers 5 moving towards each other, the upper material can also achieve synchronous softening of the shell and kernel. This allows the material to undergo more comprehensive and uniform light compression, further improving the oil yield. In addition, when the scraper 5 moves up and down, it can carry out the moisture accumulated in the bottom layer of material where the turning effect is weakest, thus effectively preventing the material from clumping. Furthermore, the discharge of high-temperature moisture also helps to improve the utilization rate of steam heat by the heat-conducting arc rod 9.
