Description
Technical Field
[0001] The present invention relates to the technical field of tea processing, and specifically to an automatic sterilization device for solid tea materials. Background Art
[0002] Solid tea materials refer to products in solid form obtained by converting the effective components of tea through specific processing techniques, such as extraction, concentration, drying, etc., using tea or fresh tea leaves as raw materials, such as solid instant tea, tea bricks, tea cakes, etc. The automatic sterilization of solid tea materials achieves efficient and uniform sterilization effects through the integration of advanced sterilization technologies, intelligent control systems, and dynamic material handling devices, while maximizing the retention of tea quality. Currently, most solid tea materials adopt automatic sterilization technologies such as steam sterilization, microwave-steam synergistic sterilization, or ultraviolet vibration sterilization. After the production of solid tea materials, they are usually stored in a warehouse, and the humidity and temperature are controlled to prevent moisture absorption, mildew, and odor pollution. However, with the increase in storage time, it is inevitable that there will be bacterial contamination in solid tea materials. Among them, tea cakes are relatively prone to mildew due to their dense internal structure. Therefore, steam sterilization work will be carried out on tea cakes after a period of storage, and steam sterilization process is mostly used for sterilizing solid tea cake materials. During the steam sterilization process of tea cakes, first, the surface of the tea cake needs to be pretreated to moderately loosen the tea cake to ensure steam penetrability and clean the surface of the tea cake. Subsequently, the staff places the tea cake flat on the tray of the steam sterilization equipment and starts the sterilization equipment to treat the bacteria in the tea cake. However, in the actual sterilization process, since most tea cakes are placed flat on the tray, the side of the tea cake close to the steam movement trajectory is heated faster, while the side wall not in the steam movement trajectory is heated relatively slower. Therefore, uneven heating often occurs. Uneven heating of the tea cake easily causes some areas to fail to reach the temperature and time required for sterilization, resulting in the survival of microorganisms in these areas and affecting the quality of the tea cake. For this reason, we propose an automatic sterilization device for solid tea materials. Summary of the Invention

Detailed implementation manner
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-11 , an automatic sterilization device for solid tea materials. The present invention correspondingly solves the technical problems in the background technology, and correspondingly improves the technical problems in the background technology. Combining the attached Figure 1 and the attached Figure 2 As shown, it includes a sterilization tank body 1. A partition board 2 is fixedly installed inside the sterilization tank body 1. Support shaft bodies 3 are fixedly installed on both the partition board 2 and the inner wall of the top of the sterilization tank body 1. A rotating shaft body 4 rotatably connected to the outer wall thereof is installed between the support shaft bodies 3. Among them, a ring-shaped vertical support 41 is fixedly installed on the rotating shaft body 4, and a plurality of annular supports 42 are installed in parallel with the vertical support 41. A breathable disc frame 5 is provided on each annular support 42. Fixed shaft bodies 421 are symmetrically installed on each annular support 42, and the breathable disc frame 5 is rotatably connected to the fixed shaft bodies 421. A torsion spring mechanism 422 connected to the breathable disc frame 5 is sleeved on the fixed shaft bodies 421. Steel telescopic parts 423 are also symmetrically installed on the annular supports 42, and the ends of the steel telescopic parts 423 are rotatably connected to the bottom of the breathable disc frame 5. It should be noted that combining the attached Figure 6As shown, the angular difference between each steel telescopic part 423 and the fixed shaft body 421 is 90°. A plurality of chambers 51 are provided on the air-permeable disc rack 5. Each chamber 51 is provided with a placement part 6 for placing tea cakes, and the tea cakes are placed vertically on the placement part 6. A servo motor 7 is fixedly installed at the bottom of the sterilization tank body 1, and the output end of the servo motor 7 is connected to the rotating shaft body 4 through a transmission unit 8; Furthermore, under the action of the transmission unit 8, the servo motor 7 causes the rotating shaft body 4 to rotate in a limited manner on the support shaft body 3, so that the rotating shaft body 4 drives the annular bracket 42 to rotate through the vertical bracket 41. The fixed shaft body 421 on the annular bracket 42 will drive the air-permeable disc rack 5 and the placement part 6 thereon to rotate, that is, the tea cakes placed vertically on the placement part 6 will perform circular motion, which can effectively improve the uniform heating rate of each part of the tea cake, improve the sterilization efficiency, and avoid the phenomenon of local overheating or overcooling of the tea cake due to uneven heating, thus ensuring the consistency of the tea cake quality.
[0020] As a further limitation in the present invention, the placement part 6 is installed in the chamber 51 and is slidably connected to the inner wall thereof by a placement frame 61, and a buffer spring 66 in contact with the end of the placement frame 61 is installed on the inner wall of the chamber 51. Combining with the attached Figure 1 and the attached Figure 2 As shown, a plurality of sealing door panels are also provided on the sterilization tank body 1. Each sealing door panel corresponds to the air-permeable disc rack 5 one by one. Furthermore, the staff can open the sealing door panel and take out the placement frame 61 on the air-permeable disc rack 5 to vertically place the tea cake on the placement frame 61. Combining with the attached Figure 6 and the attached Figure 7 As shown, a plurality of fixing nuts 62 are installed on one side of the placement frame 61. The fixing nuts 62 are threadedly connected to one side of the placement frame 61, and a plurality of locking nuts 63 are threadedly connected to the other side of the placement frame 61. The locking nuts 63 correspond to the fixing nuts 62 one by one. Silicone sleeves 67 are sleeved on the ends of both the locking nuts 63 and the fixing nuts 62. A plurality of silicone rollers 69 are fixedly installed inside the placement frame 61. During the specific use process, the staff vertically places the tea cake in the placement frame 61 and makes it contact with the silicone rollers 69. One side of the tea cake contacts the silicone sleeve 67 of the fixing nut 62, and then the locking nut 63 is rotated. The end of the locking nut 63 with the silicone sleeve 67 contacts the other side of the tea cake, thereby limiting the tea cake to ensure that the tea cake is in a vertical state; Slot 68 is provided on both sides of the placement frame 61. The second telescopic shaft body 64 is located in the slot 68 and is slidably connected to its inner wall. A return spring 65 is connected between the second telescopic shaft body 64 and the inner wall of the slot 68. A sliding groove body 511, an inclined upward groove body 512 communicating with the sliding groove body 511, a return groove body 513 communicating with the inclined upward groove body 512, and an inclined downward groove body 514 communicating with the return groove body 513 and the sliding groove body 511 are provided on the inner wall of the chamber 51. Guide panels two 515 are fixedly installed at the intersection of the sliding groove body 511 and the inclined upward groove body 512 and at the intersection of the inclined upward groove body 512 and the return groove body 513; Combined with the attached Figure 8 As shown, when the placement frame 61 is fixed in the chamber 51, the second telescopic shaft body 64 is located at the intersection of the sliding groove body 511 and the inclined upward groove body 512 and is on one side of one of the guide panels two 515. One side of the guide panel two 515 in the present invention is an inclined surface and the other side is a right-angle surface. The side located in the sliding groove body 511 is the inclined surface, and the side located in the inclined upward groove body 512 is the right-angle surface; The other guide panel two 515 located at the intersection of the inclined upward groove body 512 and the return groove body 513 has an inclined surface on the side located in the inclined upward groove body 512 and a right-angle surface on the side located in the return groove body 513; Continuing from the above, when the staff needs to take out the tea cake from the placement frame 61 or place the tea cake to be disinfected, the sealing door panel on the corresponding sterilization tank body 1 is opened, and then the placement frame 61 is pushed. The placement frame 61 squeezes the buffer spring 66. It should be noted that when the corresponding second telescopic shaft body 64 on both sides of the placement frame 61 is located at the intersection of the sliding groove body 511 and the inclined upward groove body 512, the buffer spring 66 is already in a compressed state. The second telescopic shaft bodies 64 on both sides of the placement frame 61 will then follow the trajectory of the inclined upward groove body 512 and pass through the inclined surface of another guide panel two 515, and finally enter the reset groove body 513. At this time, the reset movement of the second telescopic shaft body 64 is no longer restricted. Then, under the action of the buffer spring 66, the placement frame 61 moves in a fixed direction, that is, the second telescopic shaft body 64 moves in a fixed direction within the reset groove body 513, and finally enters the sliding groove body 511 through the inclined downward groove body 514. At this time, the end of the placement frame 61 is located outside the sterilization tank body 1, and the staff can take out the placement frame 61 and vertically place multiple tea cakes in the placement frame 61. One side of the tea cake contacts the silica gel sleeve 67 of the fixing nut 62, and then the locking nut 63 is rotated. The end of the locking nut 63 with the silica gel sleeve 67 contacts the other side of the tea cake; then the placement frame 61 with the tea cakes placed is placed in the chamber 51. During this process, the second telescopic shaft bodies 64 on the side wall of the placement frame 61 will move along the trajectory of the sliding groove body 511, pass through the guide panel two 515 at the intersection of the sliding groove body 511 and the inclined upward groove body 512, and enter the inclined upward groove body 512 along the inclined surface of the guide panel two 515. During this process, the buffer spring 66 is in a compressed state. Then, the staff no longer applies a force to the placement frame 61. The placement frame 61 is already inside the sterilization tank body 1, and if the second telescopic shaft body 64 makes a reset movement, it will be blocked by the right-angle surface of the guide panel two 515, so that the placement frame 61 is fixed on the air-permeable disc rack 5.
[0021] Combined with the attached Figure 2 and the attached Figure 3 As shown, as a further limitation in the present invention, the transmission unit 8 includes a protective frame 81 fixedly installed on the partition plate 2, and a driven gear 82 is arranged inside the protective frame 81. The driven gear 82 is fixedly connected to the rotating shaft body 4. Among them, a transmission gear 83 meshing with the driven gear 82 is also arranged inside the protective frame 81, and a connecting portion 84 rotatably connected to the inner wall of the partition plate 2 is fixedly installed on the transmission gear 83. The connecting portion 84 is connected to the output end of the servo motor 7. Combined with the attached Figure 3As shown, the connecting part 84 is in contact with the output end of the servo motor 7, and the connection is non-fixed. The end of the connecting part 84 is actually an electromagnet. After the electromagnet passes, it generates an attractive force on the magnetic output end of the servo motor 7, so that the output end of the servo motor 7 drives the end of the connecting part 84 in contact to rotate. A lockable component such as a coupling can also be installed between the two according to the actual use situation. When the servo motor 7 starts, the lockable component is used to drive the connecting part 84 to rotate. When the servo motor 7 stops running, the rotation of the connecting part 84 will not interfere with the output end of the servo motor 7 under the action of the lockable component; Combined with the attached Figure 4 As shown, a sliding shaft body 31 is also connected between the support shaft bodies 3, and the sliding shaft body 31 is slidably connected to the inner wall of the support shaft body 3. An electromagnetic component 9 is fixedly installed at the bottom of the sterilization tank body 1, and the end of the sliding shaft body 31 penetrates through the partition plate 2 and is located directly above the electromagnetic component 9. The end of the sliding shaft body 31 is a magnetic end, and when the electromagnetic component 9 is energized, it generates a repulsive force on the magnetic end of the sliding shaft body 31. A plastic spring 32 sleeved on the sliding shaft body 31 is connected between each support shaft body 3 and the sliding shaft body 31. The sliding shaft body 31 is located inside the rotating shaft body 4, and the outer wall of the sliding shaft body 31 does not contact the inner wall of the rotating shaft body 4; Combined with the attached Figure 6 and the attached Figures 9-11As shown in the figure, at the bottom of each breathable disc rack 5, drive shaft bodies 52 rotatably connected to the rotating shaft body 4 are symmetrically installed. The end of the drive shaft body 52 penetrates through the outer wall of the rotating shaft body 4 and extends into its interior. A connecting frame 53 is fixedly installed at the end of the drive shaft body 52. A movable shaft body 54 slidably connected to its inner wall is also installed inside the connecting frame 53. Below each movable shaft body 54, an annular disc rack 33 fixedly connected to the sliding shaft body 31 is provided. A through groove 34 is formed in the annular disc rack 33. The movable shaft body 54 is located on the movement track of the annular disc rack 33. A constant force spring 55 is connected between the movable shaft body 54 and the inner wall of the connecting frame 53. An expansion shaft body one 56 with a spherical end is fixedly installed on the movable shaft body 54. A steel disc rack 43 is fixedly installed on the inner wall of the rotating shaft body 4. A limiting groove body 44 for limiting the movement track of the expansion shaft body one 56 is provided on the steel disc rack 43; the limiting groove body 44 includes a reset area 441, an arc area 442 communicated with the reset area 441, and clamping areas 443 symmetrically arranged with the center line of the reset area 441 as the axis. The clamping areas 443 are communicated with the end of the arc area 442. A guiding panel one 444 is fixedly installed at the intersection of the clamping area 443 and the arc area 442; thus, when the electromagnetic component 9 is energized, it generates a repulsive force on the magnetic end of the sliding shaft body 31, so that the sliding shaft body 31 squeezes the plastic spring. During the movement of the sliding shaft body 31, the annular disc rack 33 thereon will move synchronously with it. During the movement of the annular disc rack 33, the through groove 34 thereon will approach the movable shaft body 54, that is, the movable shaft body 54 is located in the through groove 34. When the breathable disc rack 5 rotates with the rotating shaft body 4, the drive shaft body 52 thereon will rotate synchronously with it. Then, the connecting frame 53 on the drive shaft body 52 will drive the movable shaft body 54 to move synchronously. Since the movable shaft body 54 is located in the through groove 34, the movable shaft body 54 will be forced to rotate by the through groove 34 during the rotation until the end of the movable shaft body 54 is located on the surface of the annular disc rack 33. During the rotation of the movable shaft body 54, it will drive the drive shaft body 52 to rotate synchronously through the connecting frame 53, so that the breathable disc rack 5 rotates along the center line of the fixed shaft body 421. During the rotation of the movable shaft body 54, the expansion shaft body one 56 with a spherical end thereon will move along the track of the limiting groove body 44 of the steel disc rack 43, that is, the expansion shaft body one 56 enters the arc area 442 and enters the clamping area 443 through the inclined surface of the guiding panel one 444. Further explanation, one side of the guiding panel one 444 is an inclined surface and the other side is a right-angle surface; Specifically, during actual use, the staff first pre-treats the surface of the tea cake. After the treatment is completed, the sealing door panel on the sterilization tank body 1 is opened, and the vertical support 41 is rotated so that the annular support 42 drives the air-permeable disk frame 5 to rotate, that is, the placement frames 61 on each air-permeable disk frame 5 are sequentially exposed at the sealing door panel. Subsequently, the staff gently pushes the placement frame 61, so that the telescopic shafts II 64 on both sides of the placement frame 61 pass along the track of the inclined upward groove body 512 through the inclined surface of the guiding panel II 515 at the intersection of the inclined upward groove body 512 and the reset groove body 513, and finally enter the reset groove body 513. Subsequently, the placement frame 61 is reset under the action of the buffer spring 66, that is, the telescopic shaft passes along the track of the reset groove body 513 through the inclined downward groove body 514, and finally enters the sliding groove body 511. At this time, the end of the placement frame 61 is located outside the sterilization tank body 1. The staff takes out the placement frame 61 and vertically places a plurality of tea cakes in the placement frame 61. One side of the tea cake contacts the silica gel sleeve 67 of the fixing nut 62. Subsequently, the locking nut 63 is rotated, and the end of the locking nut 63 with the silica gel sleeve 67 contacts the other side of the tea cake; then the placement frame 61 with the tea cakes placed is placed in the chamber 51. During this process, the telescopic shafts II 64 on the side wall of the placement frame 61 will move along the track of the sliding groove body 511 and pass through the guiding panel II 515 at the intersection of the sliding groove body 511 and the inclined upward groove body 512, and enter the inclined upward groove body 512 along the inclined surface of the guiding panel II 515. The right-angled surface of the guiding panel II 515 obstructs the reset of the telescopic shaft II 64. This is repeated multiple times until each placement frame 61 is vertically placed with tea cakes; When the placement of the tea cakes is complete, the servo motor 7 is started. The output end of the servo motor 7 drives the meshing gear to rotate through the connecting part 84. The meshing gear meshes with the driven gear 82, so that the driven gear 82 drives the rotating shaft body 4 to rotate forward on the support shaft body 3. During the forward rotation of the rotating shaft body 4, the rotating shaft body 4 drives the annular support 42 to rotate through the vertical support 41. The fixed shaft body 421 on the annular support 42 drives the air-permeable disk frame 5 and the placement frame 61 thereon to rotate, that is, the tea cakes vertically placed on the placement frame 61 will perform circular motion. Thus, during the sterilization process in the sterilization tank body 1, the tea cakes perform circular motion, so that the steam can penetrate the tea cakes more quickly, shortening the sterilization time. At the same time, the uniform heating reduces the energy waste caused by local overheating, improving the energy utilization efficiency of the steam sterilization equipment; After sterilization for a certain period of time, the electromagnetic component 9 is energized to generate a repulsive force on the magnetic end of the sliding shaft body 31. During the directional movement of the sliding shaft body 31, the annular disc frame 33 thereon will move synchronously with it. During the movement of the annular disc frame 33, the through groove 34 thereon will approach the movable shaft body 54, that is, the movable shaft body 54 is located in the through groove 34. Subsequently, the rotating shaft body 4 rotating forward will drive the ventilation disc frame 5 to rotate synchronously. The driving shaft body 52 on the ventilation disc frame 5 will drive the movable shaft body 54 to rotate synchronously through the connecting frame 53. During this process, the telescopic shaft body 1-56 on the movable shaft body 54 is located in the reset area 441. Since the end of the movable shaft body 54 is located in the through groove 34, during the rotation of the movable shaft body 54, its end is affected by the inner wall of the through groove 34 and rotates, thereby causing the ventilation disc frame 5 to rotate along the center line of the fixed shaft body 421, that is, the torsion spring mechanism 422 is in a deformed state, so that the ventilation disc frame 5 drives the placement frame 61 to adjust the angle. During the adjustment process, the steel telescopic part 423 on the annular bracket 42 will support the ventilation disc frame 5. The vertically placed tea cake in the placement frame 61 also makes a corresponding angle adjustment, so that the tea cake is inclined and located on the movement track of the steam. During the rotation of the movable shaft body 54 under the action of the through groove 34, the telescopic shaft body 1-56 thereon will enter the arc area 442 along the reset area 441 and pass through the inclined surface of the guiding panel 1-444. Here, it should be noted that the energization amount of the electromagnetic component 9 can be set by a program. That is, when the telescopic shaft body 1-56 on the movable shaft body 54 enters the clamping area 443 from the reset area 441, the energization amount of the electromagnetic component 9 at this time is M. When the electromagnetic component 9 continues to increase the energization amount, the annular disc frame 33 continues to move, that is, the movable shaft body 54 continues to adjust the angle. When the telescopic shaft body 1-56 moves along the track of the clamping area 443, the energization amount of the electromagnetic component 9 is N. Then, when the telescopic shaft body 1-56 is at the right-angle surface of the guiding panel 1-444, the angle of the ventilation disc frame 5 is limited at this time. Sterilize for a certain period of time in this state, so that the quality of each area on the surface of the tea cake is easy to contact with the steam;Subsequently, the staff can increase the power supply of the electromagnetic component 9, that is, the annular disc frame 33 continues to move upward under the action of the sliding shaft body 31, so that the movable shaft body 54 continues to rotate, that is, the telescopic shaft body 1 56 moves along the track of the clamping area 443 and finally leaves the steel disc frame 43. During this process, the movable shaft body 54 in the connecting frame 53 will stretch the constant force spring 55. Subsequently, the electromagnetic component 9 is powered off, and the annular disc frame 33 is reset with the sliding shaft body 31 under the action of the plastic spring 32, that is, the movable shaft body 54 is no longer subjected to the acting force. The air-permeable disc frame 5 makes the driving shaft body 52 drive the movable shaft body 54 to rotate back under the action of the torsion spring mechanism 422 through the connecting frame 53, that is, the telescopic shaft body 1 56 rotates along the outer wall of the steel disc frame 43. When it moves to below the reset area 441, the movable shaft body 54 will drive the telescopic shaft body 1 56 back into the reset area 441 under the action of the constant force spring 55, and at this time the air-permeable disc frame 5 returns to the normal state; the servo motor 7 changes the rotation direction to make the rotating shaft body 4 reverse, and then powers on the electromagnetic component 9 again, repeating the above operation to make the air-permeable disc frame 5 adjust the angle again, but the direction of this angle adjustment is opposite to the above angle adjustment direction. Thus, during the sterilization process of the tea cake on the air-permeable disc frame 5, the angle can be adjusted during the circular motion along with the air-permeable disc frame 5, so that the steam can more effectively penetrate into the interior of the tea cake, making each side of the tea cake evenly heated, effectively avoiding the phenomenon of local overheating or overcooling of the tea cake due to uneven heating, and thus ensuring the consistency of the tea cake quality.
