Description

Technical Field

[0001] This utility model relates to the field of food sterilization technology, specifically to a high-temperature sterilization system for the production of bagged food. Background Technology

[0002] Food packaging sterilization addresses the problems of secondary contamination of food during the packaging process, as well as the processing and sterilization of food after packaging. To date, heat sterilization remains the most important and effective method for food sterilization. Based on different processing temperatures, heat sterilization is often classified into pasteurization, high-temperature sterilization, and ultra-high-temperature sterilization.

[0003] The utility model disclosed in CN215904853U is a sterilization device for the production of ready-to-eat bagged food, including a tank. The top of the tank is connected to a filling pipe. A fixing ring is slidably connected to the top of the inner cavity of the tank. The four corners of the bottom of the fixing ring are supported by bearings and fixing rods. Mesh boxes are fixedly installed at equal intervals on the surface of the fixing rods. A driving assembly is fixedly installed at the bottom of the tank. A rotating assembly is fixedly installed in the inner cavity of the tank. The rotating assembly includes a gear and a gear ring. The gear is fixedly installed at the upper and lower ends of the surface of the fixing rod.

[0004] The aforementioned application document states that high-temperature steam is injected into the inner cavity of the tank through a filling pipe. At this time, the drive component and the rotating component work together to sterilize the products inside the mesh box at high temperature during the rotation process. However, when sterilizing large batches of products at high temperature, it is easy to cause uneven sterilization, which is not conducive to the production process. Utility Model Content

[0005] This invention proposes a high-temperature sterilization system for bagged food production, which solves the problem mentioned in the above documents that easily leads to uneven high-temperature sterilization.

[0006] The technical solution of this utility model is as follows: A high-temperature sterilization system for bagged food production includes a body, a conveying device is provided on the inner side of the body, a connecting frame is fixedly connected to the top of the body, a fan is fixedly installed on the top of the connecting frame, an air outlet pipe is provided at the bottom of the fan, and a uniform air outlet mechanism is provided at the bottom of the air outlet pipe; the uniform air outlet mechanism includes an air outlet duct, the bottom of which is connected to and fixedly connected to the air outlet pipe, a rotating rod is rotatably connected to and through the front end of the air outlet duct, a driven gear is fixedly connected to the front end of the rotating rod, a guide plate is fixedly connected to the surface of the rotating rod, a motor is fixedly installed on the top of the air outlet duct, a rotating shaft is fixedly connected to the motor through its output shaft, a driving gear is fixedly connected to the front end of the rotating shaft, a slide cylinder is fixedly connected to the front end of the air outlet duct, a return spring is provided inside the slide cylinder, a slide rod is slidably connected inside the slide cylinder through the return spring, a rack A is fixedly connected to the end of the slide rod away from the slide cylinder, a rack B is fixedly connected to the bottom of the rack A, and a deceleration mechanism is provided inside the slide cylinder.

[0007] Optionally, the air guide plate is located inside the air outlet duct, and the air guide plate is initially inclined, so that the air guide plate can guide the direction of the air discharged from the air outlet duct.

[0008] Optionally, the teeth on the driven gear are initially engaged with the teeth on the rack B. When the rack B moves, its teeth will engage with the teeth on the driven gear, causing the driven gear to rotate.

[0009] Optionally, the teeth on the drive gear mesh with the teeth on rack A in the initial state, and the drive gear is an incomplete gear. Initially, the rotation of the drive gear and the meshing of its teeth with the teeth on rack A will cause rack A to move.

[0010] Optionally, the bottom of the air outlet is close to the top of the conveying device, and the air discharged from the air outlet can blow air onto the products being transported on the conveying device.

[0011] Optionally, the deceleration mechanism includes a connecting plate and a deceleration block. The connecting plate is fixedly connected to the slide rod, and a contact block is rotatably connected to the top of the connecting plate. An elastic rope and a limiting rod are fixedly connected to the top of the connecting plate, and the deceleration block is fixedly connected to the inner wall of the slide cylinder.

[0012] Optionally, the end of the elastic rope away from the connecting plate is fixedly connected to the contact block. When the contact block is subjected to force and rotates, the elastic force of the elastic rope can drive it to return to its original position.

[0013] Optionally, the end of the contact block away from the connecting plate is arc-shaped, and the end of the contact block away from the connecting plate is close to the inner wall of the slide. When the connecting plate drives the contact block to move, the arc-shaped end of the contact block will contact the deceleration block.

[0014] Optionally, the end of the limiting rod away from the connecting plate is close to the side of the contact block, and the limiting rod can limit the direction of rotation of the contact block.

[0015] Optionally, the deceleration block is semi-cylindrical in shape and made of rubber. When the semi-cylindrical rubber deceleration block is squeezed with the contact block, it will generate greater resistance.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, by setting a uniform air outlet mechanism, when the fan is turned on to blow air onto the products conveyed on the conveying device, the motor can be turned on. At this time, the air guide plate will swing back and forth through the cooperation of components such as the rotating shaft, the drive gear, rack A, and rack B, so that the direction of the air blown out of the air outlet will change continuously. At this time, the air is heated, which can uniformly sterilize the products conveyed on the conveying device at high temperature.

[0018] 2. By incorporating a slowing mechanism, the speed at which the slide bar moves back to its original position is reduced through the cooperation of components such as the connecting plate, contact block, elastic rope, and deceleration mechanism. This makes the back-and-forth swinging speed of the air guide plate more uniform, thereby making the airflow direction change of the air outlet more uniform and improving the high-temperature sterilization effect.

[0031] Example 1

[0032] like Figures 1-6As shown, this embodiment proposes a high-temperature sterilization system for bagged food production, including a body 1. A conveying device 2 is arranged inside the body 1. A connecting frame 3 is fixedly connected to the top of the body 1. A fan 4 is fixedly installed on the top of the connecting frame 3. An air outlet pipe 5 is arranged at the bottom of the fan 4. A uniform air outlet mechanism 6 is arranged at the bottom of the air outlet pipe 5. The uniform air outlet mechanism 6 includes an air outlet duct 61. The bottom of the air outlet duct 61 is close to the top of the conveying device 2. The air discharged from the air outlet duct 61 can uniformly distribute the air. The product transported on the conveying device 2 is blown with air. The bottom of the air outlet duct 61 is connected to the bottom of the air outlet pipe 5. The front end of the air outlet duct 61 is connected to a rotating rod 62. The front end of the rotating rod 62 is fixedly connected to a driven gear 63. A guide plate 64 is fixedly connected to the surface of the rotating rod 62. The guide plate 64 is located inside the air outlet duct 61 and is initially inclined. The guide plate 64 can guide the direction of the air discharged from the air outlet duct 61. A motor 65 is fixedly mounted on the top of the air outlet duct 61. A rotating shaft 66 is fixedly connected to the motor 65 via its output shaft. A drive gear 67 is fixedly connected to the front end of the rotating shaft 66. A sliding cylinder 68 is fixedly connected to the front end of the air outlet duct 61. A return spring 69 is installed inside the sliding cylinder 68. A sliding rod 610 is slidably connected inside the sliding cylinder 68 via the return spring 69. A rack A611 is fixedly connected to the end of the sliding rod 610 away from the sliding cylinder 68. Initially, the teeth of the drive gear 67 engage with the rack A61. 1. The upper teeth mesh with each other, and the driving gear 67 is an incomplete gear. At the beginning, the driving gear 67 rotates and its teeth mesh with the upper teeth of the rack A611, which will drive the rack A611 to move. The bottom of the rack A611 is fixedly connected to the rack B612. The upper teeth of the driven gear 63 mesh with the upper teeth of the rack B612 in the initial state. When the rack B612 moves, its teeth will mesh with the upper teeth of the driven gear 63, which will drive the driven gear 63 to rotate. The slide cylinder 68 is equipped with a slowing mechanism 7.

[0033] In this embodiment, the product to be transported is placed on the conveying device 2 for transport. The fan 4 and motor 65 are turned on. When the fan 4 starts, it generates airflow that enters the air outlet duct 61 from the air outlet pipe 5 and is finally blown out by the air outlet duct 61 onto the product on the conveying device 2. During this process, a heating device can be used to blow out hot air to sterilize the product on the conveying device 2 at high temperature. The motor 65 drives the rotating shaft 66 to rotate through its output shaft. The rotation of the rotating shaft 66 drives the drive gear 67 to rotate. Initially, the upper teeth of the drive gear 67 mesh with the upper teeth of the rack A611, which drives the rack A611 to move. The movement of the rack A611 drives the rack B612 and the slide rod 610 to move. The return spring 69... When the rack B612 is stretched and moves, its teeth mesh with the teeth on the driven gear 63, causing the driven gear 63 to rotate. The rotation of the driven gear 63 causes the rotating rod 62 and the air guide plate 64 to rotate. When the driving gear 67 rotates to the toothless part and disengages from the rack A611, the return spring 69 rebounds and causes the slide rod 610 to move in the opposite direction to restore its original position. The rack A611 and rack B612 move in the opposite direction to restore their original positions. At this time, the driven gear 63 reverses to restore its original position, and the rotating rod 62 and the air guide plate 64 also reverse to restore their original positions, thus forming a cycle. The back-and-forth swing of the air guide plate 64 causes the air direction blown out of the air outlet 61 to change continuously, which can evenly sterilize the products conveyed on the conveying device 2 at high temperature.

[0034] Example 2

[0035] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The deceleration mechanism 7 includes a connecting plate 71 and a deceleration block 75. The connecting plate 71 is fixedly connected to the slide rod 610. A contact block 72 is rotatably connected to the top of the connecting plate 71. An elastic rope 73 and a limiting rod 74 are fixedly connected to the top of the connecting plate 71. The end of the elastic rope 73 away from the connecting plate 71 is fixedly connected to the contact block 72. After the contact block 72 is subjected to force and rotates, the elastic force of the elastic rope 73 can drive it to return to its original position. The deceleration block 75 is fixedly connected to the inner wall of the slide cylinder 68. 2. The end of the contact block 72 away from the connecting plate 71 is arc-shaped, and the end of the contact block 72 away from the connecting plate 71 is close to the inner wall of the slide cylinder 68. When the connecting plate 71 drives the contact block 72 to move, the arc-shaped end of the contact block 72 will contact the deceleration block 75. The end of the limiting rod 74 away from the connecting plate 71 is close to the side of the contact block 72. The limiting rod 74 can limit the direction of rotation of the contact block 72. The deceleration block 75 is semi-cylindrical in shape and is made of rubber. When the semi-cylindrical rubber deceleration block 75 is squeezed with the contact block 72, it will generate greater resistance.

[0036] In this embodiment, the movement of the slide bar 610 will drive the connecting plate 71 to move. When the connecting plate 71 moves, it will drive the contact block 72 to move. At this time, the arc-shaped end of the contact block 72 will contact the deceleration block 75. At this time, the contact block 72 will be deflected by the force and will not be squeezed too much with the deceleration block 75, thus generating greater resistance. Then the elastic rope 73 will drive the contact block 72 to return to its original position. When the return spring 69 rebounds and drives the slide bar 610 to move in the opposite direction to return to its original position, the contact block 72 cannot be deflected under the restriction of the limiting rod 74. At this time, the semi-cylindrical rubber deceleration block 75 will squeeze the contact block 72, generating greater resistance, thereby slowing down the speed of the slide bar 610 moving in the opposite direction to return to its original position. This makes the speed of the back-and-forth swing of the air guide plate 64 more uniform, thereby making the change of the air direction blown out of the air outlet 61 more uniform and improving the effect of high-temperature sterilization.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
