Description

Technical Field

[0001] The present invention relates to the technical field of perilla seed oil frying equipment, and in particular to a frying process and system for perilla seed pretreatment used in perilla seed oil production. Background Art

[0002] In the production of perilla seed oil, perilla seed pretreatment is crucial. There are many problems in traditional perilla seed pretreatment methods. For example, manual frying has low efficiency and is difficult to meet the needs of large-scale production. Moreover, the temperature control is inaccurate, which easily leads to uneven preheating and frying of perilla seeds, affecting the quality and oil yield of perilla seed oil. At the same time, there is a lack of a complete and efficient frying system, and the automation and standardization of perilla seed pretreatment cannot be achieved. Therefore, it is very necessary to develop an advanced frying process and system for perilla seed pretreatment.

[0003] In the patent with the publication number CN110760375A, a flaxseed frying and oil pressing system is disclosed, which includes a flaxseed frying part and a flaxseed oil pressing part. The flaxseed frying part includes a frying device, a cooling and temperature reduction device, and a screening device. The frying device can make the temperature inside the frying device more stable and uniform, ensuring that the flaxseeds are evenly heated inside the frying device. The cooling and temperature reduction device can spray water to cool down and increase humidity while turning the flaxseeds to accelerate heat loss. The screening device reduces the powder and debris in the flaxseeds from flying around or sticking to the chute. The oil pressing part includes an oil press, an oil residue dispersion device, a crude oil filtering device, a first oil residue conveyor, a second oil residue conveyor, a waste residue conveyor, an oil residue elevator, and a waste residue elevator. The oil residue dispersion device can disperse the lumpy oil residue to effectively prevent the lumpy oil residue from blocking the oil press. The crude oil filtering device can not only filter the crude oil but also automatically stir, thereby improving the filtering efficiency and reducing the labor intensity of workers.

[0004] The existing technology has the following defects: It is impossible to preheat perilla seeds evenly: In the existing perilla seed pretreatment, the heat transfer method of the preheating equipment is relatively single, resulting in different heat absorption of each part of the perilla seeds, and the perilla seeds are unevenly distributed in the equipment. The heat conduction is slower at the accumulation area. During subsequent frying, the perilla seeds with uneven heat absorption have different degrees of maturity, affecting the oil output quality and taste, and the oil yield will also decrease. Therefore, a structure for evenly preheating perilla seeds needs to be set up to make the perilla seeds heat more evenly as a whole, so as to maintain the consistency of maturity during subsequent frying, make the taste more pure, retain more complete nutritional components, and achieve the effects of enhancing production stability and improving product quality.

[0005] It is impossible to continuously feed, preheat, and stir-fry perilla seeds: In the existing perilla seed pretreatment, preheating and stir-frying are generally carried out separately, lacking functional modules for continuous feeding, preheating, and stir-frying. This complicates the connection links of perilla seed feeding, preheating, and stir-frying, resulting in low production efficiency. The preheating and stir-frying processes are intermittent, unable to form a stable output rhythm. Therefore, a structure for continuously feeding, preheating, and stir-frying perilla seeds needs to be set up, so that the perilla seeds are evenly heated and the process is continuous, which can retain its nutritional components to the greatest extent, improve the quality of perilla oil, make its taste more pure and its nutritional value higher, and achieve the effects of improving production efficiency and realizing large-scale stable output. Summary of the Invention

[0006] In view of the problems in the prior art such as the inability to evenly preheat perilla seeds and the inability to continuously feed, preheat, and stir-fry perilla seeds, a stir-frying process and system for perilla seed pretreatment in perilla oil production are proposed.

[0007] On the one hand, the present application provides a stir-frying system for perilla seed pretreatment in perilla oil production, and its purpose is: through the set outer wheel mechanism, the perilla seeds are evenly preheated, so that the whole perilla seeds are heated more evenly, thus maintaining the consistency of maturity during subsequent stir-frying, making its taste more pure and retaining more complete nutritional components, achieving the effects of enhancing production stability and improving product quality. Through the set inner wheel assembly and drive assembly, the perilla seeds can be continuously fed, preheated, and stir-fried, so that the perilla seeds are evenly heated and the process is continuous, which can retain its nutritional components to the greatest extent, improve the quality of perilla oil, make its taste more pure and its nutritional value higher, and achieve the effects of improving production efficiency and realizing large-scale stable output.

[0008] The technical solution of the present invention is: A stir-frying system for perilla seed pretreatment in perilla oil production includes a bracket, a support rod fixedly connected to the bracket, an inner wheel assembly arranged between the two support rods, an outer wheel mechanism rotatably connected to the outside of the inner wheel assembly, and a drive assembly installed inside the bracket. The outer wheel mechanism is used to preheat the perilla seeds, the inner wheel assembly is used to stir-fry and extract oil from the preheated perilla seeds, the drive assembly is used to drive the inner wheel assembly and the outer wheel mechanism simultaneously. The inner wheel assembly includes a fixed inner wheel fixedly connected to the support rod, a central shaft penetrating the fixed inner wheel and rotatably connected to the inside of the support rod, and an oil-passing stirring plate fixedly connected to the outer wall of the central shaft; The outer wheel mechanism includes a rotating outer wheel rotatably connected to the outer wall of the fixed inner wheel. A feeding channel is opened inside the rotating outer wheel. One end of the feeding channel far from the fixed inner wheel is communicated with a feeding port, and one end of the feeding channel close to the fixed inner wheel is communicated with a feeding opening. A plurality of guiding components are fixedly installed on the inner wall of the feeding channel, and the guiding components are used to control the flow direction of the perilla seeds.

[0009] With the above - mentioned solution, through the externally - set wheel mechanism, the drained perilla seeds are put into the material - passing channel from the feeding port. The perilla seeds pass through the material - passing channel and reach the first guiding wheel. At the same time, there are the perilla seeds pre - heated in the previous batch in the fixed inner wheel. The operation of the driving component drives the rotating outer wheel and the central shaft to rotate synchronously. The rotation direction of the servo motor is set. In the initial state, it rotates clockwise by 90° first, so that the perilla seeds enter the first corner of the material - passing channel through the first guiding wheel. Then it rotates clockwise by 90° again, so that the perilla seeds flow between the first corner and the second corner of the material - passing channel. Then it rotates counter - clockwise by 180°, so that the perilla seeds reach the second guiding wheel. Then it rotates counter - clockwise by 90°, so that the perilla seeds enter the second corner of the material - passing channel through the second guiding wheel. Then it continues to rotate counter - clockwise by 90°, so that the perilla seeds flow between the second corner and the third corner of the material - passing channel. Finally, it rotates clockwise by 180°, so that the perilla seeds reach the third guiding wheel. It rotates forward and backward repeatedly until the perilla seeds reach the discharging port. Thus, the perilla seeds are uniformly pre - heated, making the perilla seeds heat more evenly as a whole, thereby maintaining the consistency of maturity during subsequent frying, making its taste more pure and retaining more complete nutritional components, achieving the effect of enhancing production stability and improving product quality.

[0010] Further, a plurality of partition plates are fixedly connected to the inner wall of the rotating outer wheel. The plurality of partition plates evenly divide the material - passing channel into multiple parts for diverting the perilla seeds. A discharging port is also opened on the inner wall of the rotating outer wheel, and the discharging port is arranged opposite to the feeding port.

[0011] With the above - mentioned solution, through the set partition plates and discharging port, the partition plates can evenly distribute a batch of raw materials into multiple portions and put them into the material - passing channel. Through the discharging port, the fried perilla seeds can fall into the discharging cart, playing the role of diverting raw materials and providing a discharging channel.

[0012] Further, the guiding component includes a guiding wheel rotatably connected between two adjacent partition plates and a guiding block fixedly installed on the inner wall of the material - passing channel. A limiting groove is opened on the inner wall of the guiding block, and a reverse blocking plate is rotatably connected to the inner wall of the guiding block. The reverse blocking plate will block the reverse rotation of the guiding wheel under the action of gravity.

[0013] With the above - mentioned solution, through the set guiding component, the perilla seeds can slowly penetrate into the material - passing channel through the rotation of the rotating outer wheel and the guiding of the guiding block. And due to the reverse blocking of the reverse blocking plate, the perilla seeds can be prevented from remaining in the material - passing channel.

[0014] Further, a material - passing sliding door and a discharging sliding door are slidably connected to the outer wall of the fixed inner wheel. When the material - passing sliding door is opened, the rotating outer wheel and the fixed inner wheel are communicated through the material - passing port. When the discharging sliding door is opened, the perilla seeds inside the fixed inner wheel are discharged through the discharging port.

[0015] Further, pull rods are fixedly connected to the outer walls of the material-passing sliding door and the discharging sliding door. A sliding rod is slidably connected to the inner wall of the pull rod, and the sliding rod can be inserted into the pull rod to form an integral body with the pull rod.

[0016] Further, a plurality of heating rods are fixedly connected to the inner wall of the fixed inner wheel. The heating rods provide temperature for the interior of the fixed inner wheel and the material-passing channel, and the part of the material-passing channel closer to the heating rods has a higher temperature.

[0017] With the above solution, through the inner wheel assembly provided, after the perilla seeds are preheated and fried, the servo motor is turned off, so that the rotating outer wheel and the oil-passing stirring plate stop at the initial state. At this time, the sliding rod can be inserted into the pull rod through the through slot, and then the pull rod is pulled to open the material-passing sliding door and the discharging sliding door. The fried perilla seeds fall into the discharging truck through the discharging port, and the residues and perilla seed oil are filtered out by the residue filter plate. The preheated perilla seeds enter the interior of the fixed inner wheel through the material-passing port and are blocked by the oil-passing stirring plate to prevent the preheated perilla seeds from being mixed with the fried perilla seeds. At the same time, a new batch of perilla seeds is put into the feeding port, and then the material-passing sliding door and the discharging sliding door are closed, playing a role in continuous operation.

[0018] Further, the driving assembly includes a servo motor fixedly installed on the inner wall of the bracket. The output shaft of the servo motor is fixedly connected with a driving gear. A connecting plate is fixedly connected to the outer wall of the rotating outer wheel, and a transmission gear ring is fixedly connected to the outer wall of the connecting plate. The transmission gear ring meshes with the driving gear, and two through slots are formed in the inner wall of the connecting plate.

[0019] Further, the driving assembly further includes a driven shaft fixedly installed on the inner wall of the bracket. A synchronous transmission belt is connected between the driven shaft and the central shaft in a transmission manner. A driven gear is fixedly connected to the outer wall of the driven shaft, and the driven gear also meshes with the driving gear.

[0020] With the above solution, through the driving assembly provided, the servo motor is operated. The output shaft of the servo motor drives the transmission gear ring and the driven gear to rotate synchronously through the driving gear. Among them, the transmission gear ring drives the rotating outer wheel to rotate outside the fixed inner wheel through the connecting plate, and the driven gear drives the central shaft to rotate inside the support rod through the driven shaft and the synchronous transmission belt, thereby driving the oil-passing stirring plate to stir the preheated perilla seeds inside the fixed inner wheel, playing a role in providing synchronous rotation power.

[0021] Further, a discharging truck is arranged directly below the rotating outer wheel, and a residue filter plate is fixedly connected to the inner wall of the discharging truck.

[0022] With the above solution, through the discharging truck provided, the fried perilla seeds can fall into the discharging truck through the discharging port, and the residues and perilla seed oil are filtered out by the residue filter plate.

[0023] On the other hand, the present application provides a process for frying system in the pre-treatment of perilla seeds for perilla seed oil production. Using a frying system for pre-treatment of perilla seeds for perilla seed oil production, the process comprises the following steps: Step 1: The drained perilla seeds enter the material passing channel through the feeding port; Step 2: Operate the driving component to drive the rotating outer wheel and the central shaft to rotate simultaneously; Step 3: The perilla seeds are guided and circulated in the material passing channel by the guiding component; Step 4: When the perilla seeds reach the material passing port, stop the driving component and open the material passing sliding door and the discharging sliding door; Step 5: The preheated perilla seeds enter the interior of the fixed inner wheel through the material passing port and are blocked by the oil-passing stirring plate; Step 6: The original fried perilla seed residues and perilla seed oil flow into the discharging truck through the discharging port; Step 7: Close the material passing sliding door and the discharging sliding door; Step 8: Repeat Steps 1 to 7 to continuously preheat and fry.

[0024] With the above solution, the drained perilla seeds are put into the material passing channel through the feeding port, and a batch of raw materials are evenly distributed into multiple portions by the partition plate, which is conducive to the uniform preheating of the perilla seeds. The perilla seeds reach the first guiding wheel through the material passing channel. At the same time, there are the perilla seeds preheated in the previous batch in the fixed inner wheel. Operate the driving component to drive the rotating outer wheel and the central shaft to rotate synchronously, and the rotation direction of the servo motor is set to perform periodic forward and reverse rotations. The perilla seeds slowly penetrate in the material passing channel through the rotation of the rotating outer wheel, and the temperature also rises accordingly, making the preheating more linear and uniform. And through the guiding of the guiding block and the reverse blocking of the reverse baffle plate, the perilla seeds are prevented from remaining in the material passing channel. At the same time, the oil-passing stirring plate continuously stirs the preheated perilla seeds in the fixed inner wheel in the forward or reverse direction, making the frying of the perilla seeds more uniform. When the perilla seeds reach the material passing port, the preheating is completed and the frying is also completed. Turn off the servo motor to stop the rotating outer wheel and the oil-passing stirring plate in the initial state. At this time, a sliding rod can be inserted into the pull rod through the through groove, and then the pull rod is pulled to open the material passing sliding door and the discharging sliding door. The fried perilla seeds fall into the discharging truck through the discharging port, and the residues and perilla seed oil are filtered out through the residue filter plate. The preheated perilla seeds enter the interior of the fixed inner wheel through the material passing port and are blocked by the oil-passing stirring plate to prevent the preheated perilla seeds from being mixed with the fried perilla seeds. At the same time, a new batch of perilla seeds are put into the feeding port, and then the material passing sliding door and the discharging sliding door are closed for continuous operation.

[0025] Advantages of the present invention: Through the set outer wheel mechanism, the drained perilla seeds are put into the material passing channel from the feeding port. The perilla seeds reach the first guide wheel through the material passing channel. At the same time, there are the perilla seeds preheated in the previous batch in the fixed inner wheel. The operation of the driving component drives the rotating outer wheel and the central shaft to rotate synchronously. The rotation direction of the servo motor is set to perform periodic forward and reverse rotations. Thus, the perilla seeds are evenly preheated, making the overall heating of the perilla seeds more uniform, thereby maintaining the consistency of maturity during subsequent frying, making its taste more pure and the nutrient components more completely retained, achieving the effect of enhancing production stability and improving product quality.

[0026] Through the set inner wheel component, after the perilla seeds are preheated and fried, the servo motor is turned off, so that the rotating outer wheel and the oil-passing stirring plate stop at the initial state. At this time, the sliding rod can be inserted into the pull rod at the through groove, and then the pull rod is pulled to open the material passing sliding door and the discharging sliding door. The fried perilla seeds fall into the discharging truck through the discharging port, and the residues and perilla seed oil are filtered out through the residue filter plate. The preheated perilla seeds enter the inside of the fixed inner wheel through the material passing port and are blocked by the oil-passing stirring plate to prevent the preheated perilla seeds from being mixed with the fried perilla seeds. At the same time, a new batch of perilla seeds is put into the feeding port, and then the material passing sliding door and the discharging sliding door are closed, playing a role in continuous operation.

[0027] Through the set driving component, the servo motor is operated. The output shaft of the servo motor synchronously drives the transmission gear ring and the driven gear to rotate through the driving gear. Among them, the transmission gear ring drives the rotating outer wheel to rotate outside the fixed inner wheel through the connecting plate, and the driven gear drives the central shaft to rotate inside the support rod through the driven shaft and the synchronous transmission belt, thereby driving the oil-passing stirring plate to stir the preheated perilla seeds inside the fixed inner wheel, playing a role in providing synchronous rotation power.

Specific embodiments

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0031] Example 1, referring to Figure 1 - Figure 10 , which is the first embodiment of the present invention, provides a frying system for pre-treating perilla seeds for perilla oil production, including a bracket 1, a support rod 2 fixedly connected to the bracket 1, an inner wheel assembly 3 disposed between the two support rods 2, an outer wheel mechanism 4 rotatably connected to the outside of the inner wheel assembly 3, and a driving component 5 installed inside the bracket 1. The outer wheel mechanism 4 is used to preheat the perilla seeds, the inner wheel assembly 3 is used to fry and extract oil from the preheated perilla seeds, and the driving component 5 is used to drive the inner wheel assembly 3 and the outer wheel mechanism 4 simultaneously. The inner wheel assembly 3 includes a fixed inner wheel 31 fixedly connected to the support rod 2, a central shaft 32 penetrating the fixed inner wheel 31 and rotatably connected to the inside of the support rod 2, and an oil-passing stirring plate 33 fixedly connected to the outer wall of the central shaft 32.

[0032] Referring to Figure 3 - Figure 4 , the outer wheel mechanism 4 includes a rotating outer wheel 41 rotatably connected to the outer wall of the fixed inner wheel 31. A material-passing channel 44 is opened inside the rotating outer wheel 41. One end of the material-passing channel 44 away from the fixed inner wheel 31 communicates with a feeding port 43, and one end of the material-passing channel 44 close to the fixed inner wheel 31 communicates with a material-passing port 45. A plurality of guide assemblies 46 are fixedly installed on the inner wall of the material-passing channel 44, and the guide assemblies 46 are used to control the flow direction of the perilla seeds.

[0033] Specifically, two brackets 1 are provided. Each of the two brackets 1 is connected to a support rod 2. The inner wheel assembly 3 is arranged between the two support rods 2. When the driving assembly 5 operates, it can drive the rotating outer wheel 41 and the central shaft 32 to rotate synchronously. The material passing channel 44 is opened inside the fixed inner wheel 31, and a plurality of guiding assemblies 46 are arranged inside it. Through the forward and reverse rotation of the outer wheel mechanism 4, the guiding assemblies 46 can slowly guide the perilla seeds into the interior of the material passing channel 44 until the material passing opening 45.

[0034] Through the provided outer wheel mechanism 4, the drained perilla seeds are put into the material passing channel 44 from the feeding port 43. The perilla seeds pass through the material passing channel 44 and reach the first guiding wheel 461. At the same time, there are the perilla seeds preheated in the previous batch in the fixed inner wheel 31. The driving assembly 5 is operated to drive the rotating outer wheel 41 and the central shaft 32 to rotate synchronously. The rotation direction of the servo motor 51 is set. In the initial state, it rotates clockwise by 90° first, so that the perilla seeds enter the first corner of the material passing channel 44 through the first guiding wheel 461. Then it rotates clockwise by 90° again, so that the perilla seeds flow between the first corner and the second corner of the material passing channel 44. Then it rotates counterclockwise by 180°, so that the perilla seeds reach the second guiding wheel 461. Then it rotates counterclockwise by 90°, so that the perilla seeds enter the second corner of the material passing channel 44 through the second guiding wheel 461. Then it continues to rotate counterclockwise by 90°, so that the perilla seeds flow between the second corner and the third corner of the material passing channel 44. Finally, it rotates clockwise by 180°, so that the perilla seeds reach the third guiding wheel 461. By repeatedly rotating forward and backward, until the perilla seeds reach the material passing opening 45. Thus, the perilla seeds are uniformly preheated, making the perilla seeds heat more evenly as a whole, thereby maintaining the consistency of maturity during subsequent frying, making its taste more pure and the nutritional components more completely retained, achieving the effects of enhancing production stability and improving product quality.

[0035] Refer to Figure 3 As shown in the figure, a plurality of partition plates 42 are fixedly connected to the inner wall of the rotating outer wheel 41. The plurality of partition plates 42 evenly divide the material passing channel 44 into multiple parts for diverting the perilla seeds. A discharge opening 47 is also opened on the inner wall of the rotating outer wheel 41. The discharge opening 47 is arranged opposite to the feeding port 43.

[0036] Through the provided partition plates 42 and discharge opening 47, the partition plates 42 can evenly distribute a batch of raw materials into multiple portions and put them into the material passing channel 44. Through the discharge opening 47, the fried perilla seeds can fall into the discharge truck 6, playing the role of raw material diversion and providing a discharge channel.

[0037] Refer to Figure 5, the guiding assembly 46 includes a guiding wheel 461 rotatably connected between two adjacent partition plates 42, and a guiding block 462 fixedly installed on the inner wall of the material passing channel 44. A limiting groove 463 is formed on the inner wall of the guiding block 462, and a reverse blocking plate 464 is rotatably connected to the inner wall of the guiding block 462. Under the action of gravity, the reverse blocking plate 464 blocks the reverse rotation of the guiding wheel 461.

[0038] Specifically, the reverse blocking plate 464 can swing in the limiting groove 463. When the guiding wheel 461 rotates forward, it can guide and discharge the perilla seeds. When rotating in the reverse direction, the reverse blocking plate 464 can block the rotation of the guiding wheel 461.

[0039] Through the arranged guiding assembly 46, the perilla seeds can slowly penetrate in the material passing channel 44 through the rotation of the rotating outer wheel 41 and the guiding of the guiding block 462, and the reverse blocking of the reverse blocking plate 464 can prevent the perilla seeds from remaining in the material passing channel 44.

[0040] Refer to Figure 6 - Figure 8 , a material passing sliding door 34 and a discharging sliding door 35 are slidably connected to the outer wall of the fixed inner wheel 31. When the material passing sliding door 34 is opened, the rotating outer wheel 41 and the fixed inner wheel 31 are communicated through the material passing port 45. When the discharging sliding door 35 is opened, the perilla seeds inside the fixed inner wheel 31 are discharged through the discharging port 47. Pulling rods 36 are fixedly connected to the outer walls of the material passing sliding door 34 and the discharging sliding door 35. A sliding rod 37 is slidably connected to the inner wall of the pulling rod 36. The sliding rod 37 can be inserted into the pulling rod 36 to become an integral body with the pulling rod 36. A plurality of heating rods 38 are fixedly connected to the inner wall of the fixed inner wheel 31. The heating rods 38 provide temperature for the inside of the fixed inner wheel 31 and the material passing channel 44. The part of the material passing channel 44 closer to the heating rod 38 has a higher temperature.

[0041] Through the arranged inner wheel assembly 3, after the perilla seeds are preheated and stir-fried, the servo motor 51 is turned off to make the rotating outer wheel 41 and the oil-passing stirring plate 33 stop in the initial state. At this time, the sliding rod 37 can be inserted into the pulling rod 36 through the through groove 55, and then the pulling rod 36 is pulled to open the material passing sliding door 34 and the discharging sliding door 35. The stir-fried perilla seeds fall into the discharging cart 6 through the discharging port 47, and the residues and perilla seed oil are filtered out by the residue filtering plate 61. The preheated perilla seeds enter the inside of the fixed inner wheel 31 through the material passing port 45 and are blocked by the oil-passing stirring plate 33 to prevent the preheated perilla seeds from being mixed with the stir-fried perilla seeds. At the same time, a new batch of perilla seeds is put into the feeding port 43, and then the material passing sliding door 34 and the discharging sliding door 35 are closed, playing a role in continuous operation.

[0042] Refer to Figure 9The driving assembly 5 includes a servo motor 51 fixedly mounted on the inner wall of the bracket 1, the output shaft of the servo motor 51 is fixedly connected to a driving gear 52, the outer wall of the rotating outer wheel 41 is fixedly connected to a connecting plate 54, the outer wall of the connecting plate 54 is fixedly connected to a transmission ring gear 53, the transmission ring gear 53 is meshed with the driving gear 52, and the inner wall of the connecting plate 54 is provided with two through grooves 55. The driving assembly 5 also includes a driven shaft 56 fixedly mounted on the inner wall of the bracket 1, a synchronous transmission belt 58 is transmission-connected between the driven shaft 56 and the central shaft 32, and a driven gear 57 is fixedly connected to the outer wall of the driven shaft 56, and the driven gear 57 is also meshed with the driving gear 52.

[0043] By means of the drive assembly 5, the servo motor 51 is operated, and the output shaft of the servo motor 51 synchronously drives the transmission ring gear 53 and the driven gear 57 to rotate via the driving gear 52, wherein the transmission ring gear 53 drives the rotating outer wheel 41 to rotate outside the fixed inner wheel 31 via the connecting plate 54, and the driven gear 57 drives the central shaft 32 to rotate inside the support rod 2 via the driven shaft 56 and the synchronous transmission belt 58, thereby driving the oil-passing stirring plate 33 to stir the preheated perilla seeds inside the fixed inner wheel 31, thereby providing synchronous rotation power.

[0044] Reference Figure 3 A discharge cart 6 is arranged directly below the rotating outer wheel 41 , and a residue filtering plate 61 is fixedly connected to the inner wall of the discharge cart 6 .

[0045] Through the provided unloading vehicle 6 , the roasted perilla seeds can fall into the unloading vehicle 6 through the unloading port 47 , and the residue and perilla seed oil can be filtered out through the residue filtering plate 61 .

[0046] During the use process, the drained perilla seeds are put into the material passing channel 44 from the feeding port 43, and a batch of raw materials are evenly distributed into multiple portions by the partition plate 42, which is conducive to the uniform preheating of the perilla seeds. The perilla seeds reach the first guide wheel 461 through the material passing channel 44. At the same time, there are perilla seeds preheated in the previous batch in the fixed inner wheel 31. The driving assembly 5 is operated to drive the rotating outer wheel 41 and the central shaft 32 to rotate synchronously, and the rotation direction of the servo motor 51 is set to perform periodic forward and reverse rotations. The perilla seeds slowly penetrate in the material passing channel 44 through the rotation of the rotating outer wheel 41, and the temperature also rises accordingly, making the preheating more linear and uniform. And through the guidance of the guide block 462 and the reverse blocking of the reverse blocking plate 464, the perilla seeds are prevented from remaining in the material passing channel 44. At the same time, the oil-passing stirring plate 33 continuously stirs the preheated perilla seeds in the fixed inner wheel 31 in the forward or reverse direction, making the frying of the perilla seeds more uniform. When the perilla seeds reach the material passing port 45, the preheating is completed, and at the same time, the frying is also completed. The servo motor 51 is turned off to make the rotating outer wheel 41 and the oil-passing stirring plate 33 stop in the initial state. At this time, the sliding rod 37 can be inserted into the inside of the pull rod 36 at the through groove 55, and then the pull rod 36 is pulled to open the material passing sliding door 34 and the discharging sliding door 35. The fried perilla seeds fall into the discharging truck 6 through the discharging port 47, and the residues and perilla seed oil are filtered out through the residue filter plate 61. The preheated perilla seeds enter the inside of the fixed inner wheel 31 through the material passing port 45 and are blocked by the oil-passing stirring plate 33 to prevent the preheated perilla seeds from being mixed with the fried perilla seeds. At the same time, a new batch of perilla seeds are put into the feeding port 43, and then the material passing sliding door 34 and the discharging sliding door 35 are closed to carry out continuous operation.

[0047] Example 2, refer to Figure 1 - Figure 10 , a process for a frying system for perilla seed pretreatment for perilla seed oil production is provided. A frying system for perilla seed pretreatment for perilla seed oil production is used, which comprises the following steps: Step 1: The drained perilla seeds enter the material passing channel 44 from the feeding port 43; Step 2: The driving assembly 5 is operated to drive the rotating outer wheel 41 and the central shaft 32 to rotate simultaneously; Step 3: The perilla seeds are guided and circulated in the material passing channel 44 by the guiding assembly 46; Step 4: When the perilla seeds reach the material passing port 45, the driving assembly 5 is stopped, and the material passing sliding door 34 and the discharging sliding door 35 are opened; Step 5: The preheated perilla seeds enter the inside of the fixed inner wheel 31 through the material passing port 45 and are blocked by the oil-passing stirring plate 33; Step 6: The residues and perilla seed oil of the original fried perilla seeds flow into the discharging truck 6 through the discharging port 47; Step 7: The material passing sliding door 34 and the discharging sliding door 35 are closed; Step 8: Repeat Steps 1 to 7 to continuously preheat and fry.

[0048] Working principle of the present invention: During operation, the drained perilla seeds are put into the material passing channel 44 from the feeding port 43, and a batch of raw materials are evenly distributed into multiple portions by the partition plate 42, which is conducive to the uniform preheating of the perilla seeds. The perilla seeds reach the first guide wheel 461 through the material passing channel 44. At the same time, there are perilla seeds preheated in the previous batch in the fixed inner wheel 31.

[0049] Operate the servo motor 51. The output shaft of the servo motor 51 synchronously drives the transmission gear ring 53 and the driven gear 57 to rotate through the driving gear 52. Among them, the transmission gear ring 53 drives the rotating outer wheel 41 to rotate outside the fixed inner wheel 31 through the connecting plate 54, and the driven gear 57 drives the central shaft 32 to rotate inside the support rod 2 through the driven shaft 56 and the synchronous transmission belt 58, so as to drive the oil-passing stirring plate 33 to stir the preheated perilla seeds inside the fixed inner wheel 31.

[0050] The rotation direction of the servo motor 51 is set. In the initial state, it rotates clockwise by 90° first, so that the perilla seeds enter the first corner of the material passing channel 44 through the first guide wheel 461. Then it rotates clockwise by 90° again, so that the perilla seeds flow between the first corner and the second corner of the material passing channel 44. Then it rotates counterclockwise by 180°, so that the perilla seeds reach the second guide wheel 461. Then it rotates counterclockwise by 90°, so that the perilla seeds enter the second corner of the material passing channel 44 through the second guide wheel 461. Then it continues to rotate counterclockwise by 90°, so that the perilla seeds flow between the second corner and the third corner of the material passing channel 44. Finally, it rotates clockwise by 180°, so that the perilla seeds reach the third guide wheel 461. It rotates forward and backward repeatedly until the perilla seeds reach the feeding port 45.

[0051] The perilla seeds slowly penetrate in the material passing channel 44 through the rotation of the rotating outer wheel 41, and the temperature also rises accordingly, making the preheating more linear and uniform. Generally, the perilla seeds are gradually heated to 80°C to 120°C during the preheating stage. And through the guiding of the guiding block 462 and the reverse blocking of the reverse blocking plate 464, the perilla seeds are prevented from remaining in the material passing channel 44. At the same time, the oil-passing stirring plate 33 continuously stirs the preheated perilla seeds in the fixed inner wheel 31 in the forward or reverse direction, making the frying of the perilla seeds more uniform.

[0052] After the perilla seeds reach the feeding port 45, the preheating is completed, and at the same time, the frying is also completed. The servo motor 51 is turned off, so that the rotating outer wheel 41 and the oil-passing stirring plate 33 stop at the initial state. At this time, a slide bar 37 can be inserted into the inside of the pull rod 36 at the through groove 55, and then the pull rod 36 is pulled to open the feeding sliding door 34 and the discharging sliding door 35. The fried perilla seeds fall into the discharging truck 6 through the discharging port 47, and the residue and perilla oil are filtered out through the residue filter plate 61. The preheated perilla seeds enter the inside of the fixed inner wheel 31 through the feeding port 45 and are blocked by the oil-passing stirring plate 33 to prevent the preheated perilla seeds from being mixed with the fried perilla seeds. At the same time, a new batch of perilla seeds is put into the feeding port 43, and then the feeding sliding door 34 and the discharging sliding door 35 are closed for continuous operation.
