Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable canning technology, specifically to a continuous pasteurization structure for fruit and vegetable canning production lines. Background Technology

[0002] Canned fruits and vegetables are a very popular food. They are preserved by sealing fruits and vegetables in airtight jars, significantly extending their shelf life and enhancing their unique flavor. During the canning process, pasteurization is used to kill bacteria. Pasteurization is a sterilization method that uses relatively low temperatures to kill germs while preserving the nutrients and flavor of the produce, thus ensuring the original flavor of the canned fruits and vegetables while eliminating harmful bacteria.

[0003] Chinese Patent Publication No. CN220000616U discloses a continuous pasteurization mechanism for a fruit canning production line, including a pasteurization chamber. A heating tube is fixedly connected to the bottom of the pasteurization chamber, and a cover plate is fixedly connected to the upper side of the chamber. A conveying mechanism connects the cover plate and the pasteurization chamber, and cans are placed on the conveying mechanism. The conveying mechanism includes a conveyor plate connected inside the pasteurization chamber, with both ends of the conveyor plate bent upwards. Material holes are provided on both the left and right sides of the pasteurization chamber, and the two ends of the conveyor plate extend out of the chamber through two material holes respectively. A limiting groove is provided on the upper side of the conveyor plate, and the cans are located within the limiting groove. A conveyor belt is fixedly connected to the lower side wall of the cover plate, and multiple pusher plates are fixedly connected to the outer wall of the conveyor belt, with the pusher plates evenly distributed on the conveyor belt. This invention effectively improves the continuity of the pasteurization mechanism and increases the production efficiency of canned goods.

[0004] However, the above-mentioned existing technologies cannot sterilize every side of the canned food, and if the residual steam after sterilization in the sterilization chamber is not absorbed, it will result in waste. Utility Model Content

[0005] The purpose of this invention is to provide a continuous pasteurization structure for fruit and vegetable canning production lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuous pasteurization structure for a fruit and vegetable canning production line includes a sterilization chamber and a fixed frame. A fixed box is fixedly connected to the top of the sterilization chamber, and an air extractor is fixedly connected inside the fixed box. An air suction pipe is fixedly connected to one side of the air extractor. Two hanging rods are fixedly connected to the top of the sterilization chamber. A connecting plate is fixedly connected to the bottom of the hanging rods. An electric telescopic rod is fixedly connected to the surface of the connecting plate. A fixed plate is fixedly connected to the telescopic end of the electric telescopic rod. Multiple connecting parts are fixedly connected to the bottom of the fixed plate. A second motor is fixedly connected to one end of each connecting part. A bidirectional lead screw is fixedly connected to the output end of the second motor. One end of the bidirectional lead screw is rotatably connected to the inner side of the connecting part. Two threaded seats are threaded onto the surface of the bidirectional lead screw. A gripper is fixedly connected to the bottom of each threaded seat. An anti-slip pad is fixedly connected to the inner side of the bottom of the gripper.

[0008] Preferably, one end of the suction pipe is fixedly inserted through and extends into the sterilization chamber, and an air inlet pipe is fixedly connected to one side of the sterilization chamber.

[0009] Preferably, a first motor is fixedly connected to one side of the fixed frame, a drive roller is fixedly connected to the output end of the first motor, a conveyor belt is drivenly connected to the surface of the drive roller, and a driven roller is drivenly connected to the inner side of one end of the conveyor belt.

[0010] Preferably, one end of the driving roller and both ends of the driven roller are rotatably connected to the inner side of the fixed frame, and multiple placement slots are fixedly connected to the surface of the conveyor belt.

[0011] Preferably, a control panel is fixedly connected to the surface of the sterilization box, and transparent curtains are provided on both sides of the sterilization box.

[0012] Preferably, the control panel is electrically connected to the first motor, the second motor, the vacuum pump, and the electric telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, to ensure thorough sterilization of the bottom of the can, the electric telescopic rod is activated via the control panel. This rod moves the fixed plate downwards, which in turn moves multiple connecting parts downwards, causing the grippers to move downwards until they reach both sides of the can. Then, the second motor is activated, driving a bidirectional lead screw to rotate. This screw rotates two lead screw seats in corresponding directions, which in turn move the grippers in the corresponding directions, ultimately bringing the anti-slip pads close to the can until it is clamped tightly. The electric telescopic rod is then activated again, moving the clamped can upwards to further sterilize the bottom. After sterilization, the vacuum pump is activated via the control panel. This pump uses a suction pipe to absorb residual steam inside the sterilization chamber for recycling or other purposes, thus solving the problems of insufficient sterilization and wasted steam.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a continuous pasteurization structure for a fruit and vegetable canning production line, including a sterilization box 1 and a fixing frame 2. A fixing box 6 is fixedly connected to the top of the sterilization box 1. An air extractor 17 is fixedly connected inside the fixing box 6. An air suction pipe 8 is fixedly connected to one side of the air extractor 17. One end of the air suction pipe 8 is fixedly inserted through and extends into the interior of the sterilization box 1. An air inlet pipe 7 is fixedly connected to one side of the sterilization box 1. Two hanging rods 13 are fixedly connected to the top of the interior of the sterilization box 1. A connecting plate 14 is fixedly connected to the bottom of the hanging rods 13. An electric telescopic rod 15 is fixedly connected to the surface of the connecting plate 14. A fixing plate 16 is fixedly connected to the telescopic end of the electric telescopic rod 15. Multiple connecting parts 19 are fixedly connected to the bottom of the fixing plate 16. A second motor 18 is fixedly connected to one end of the connecting parts 19. A bidirectional lead screw 20 is fixedly connected to the output end of the second motor 18. One end of the bidirectional lead screw 20 is rotatably connected to the inner side of the connecting parts 19. Two threaded seats 21 are threadedly connected to the surface of the bidirectional lead screw 20. A clamp 22 is fixedly connected to the bottom of the threaded seats 21. The gripper 22 has an anti-slip pad 23 fixedly connected to its inner bottom. When the electric telescopic rod 15 is activated, it moves the fixed plate 16 downward. The downward movement of the fixed plate 16 moves multiple connecting parts 19 downward, thereby moving the gripper 22 downward until it reaches both sides of the can. Then, the second motor 18 is activated, which drives the bidirectional lead screw 20 to rotate. The rotation of the bidirectional lead screw 20 moves the two lead seats 21 in the corresponding directions, thereby moving the gripper 22 in the corresponding directions. Finally, the anti-slip pad 23 is brought close to the can until it is clamped. Then, the electric telescopic rod 15 is activated again, which moves the clamped can upward, thus sterilizing the bottom of the can. After sterilization, there may be residual steam inside the sterilization chamber 1. If it is not recovered, it will easily cause waste. Therefore, by activating the vacuum pump 17, the vacuum pump 17 will drive the suction pipe 8 to absorb the residual steam inside the sterilization chamber 1 for recycling or other purposes.

[0023] like Figure 1 and Figure 2 As shown, a first motor 5 is fixedly connected to one side of the fixed frame 2. An active roller 11 is fixedly connected to the output end of the first motor 5. A conveyor belt 3 is driven to the surface of the active roller 11. A driven roller 12 is driven to the inner side of one end of the conveyor belt 3. One end of the active roller 11 and both ends of the driven roller 12 are rotatably connected to the inner side of the fixed frame 2. Multiple placement slots 4 are fixedly connected to the surface of the conveyor belt 3. The cans are placed in the placement slots 4, and then the first motor 5 is started. The first motor 5 drives the active roller 11 to rotate, thereby driving the conveyor belt 3 to rotate, thus driving the cans on the surface to be transported.

[0024] like Figure 1As shown, a control panel 10 is fixedly connected to the surface of the sterilization chamber 1. Transparent curtains 9 are respectively provided on both sides of the sterilization chamber 1. The control panel 10 is electrically connected to the first motor 5, the second motor 18, the exhaust fan 17 and the electric telescopic rod 15. The transparent curtains 9 can prevent steam from escaping too quickly and affecting sterilization. The control panel 10 is used to open and close the first motor 5, the second motor 18, the exhaust fan 17 and the electric telescopic rod 15.

[0025] Working principle: When in use, first introduce steam into sterilization chamber 1 through air inlet pipe 7 until the sterilization conditions suitable for the current canned food are introduced, and then place the canned food in placement slot 4;

[0026] The first motor 5 is started by controlling the control panel. The first motor 5 drives the drive roller 11 to rotate, which in turn drives the conveyor belt 3 to rotate, thereby conveying the cans on the surface. Since the distance between the two placement slots 4 is the same as the distance between the two grippers 22, the cans can be conveyed to the inside of the sterilization box 1 directly below the grippers 22 under the action of the conveyor belt 3. At this time, the first motor 5 is turned off, the conveyor belt 3 stops conveying, and the cans can be sterilized.

[0027] To ensure thorough sterilization of the bottom of the can, the electric telescopic rod 15 is activated via the control panel. The electric telescopic rod 15 moves the fixing plate 16 downwards, which in turn moves multiple connecting parts 19 downwards, causing the gripper 22 to move downwards until it reaches both sides of the can. Then, the second motor 18 is activated, driving the bidirectional lead screw 20 to rotate. The bidirectional lead screw 20 rotates, causing two lead seats 21 to move in corresponding directions, which in turn moves the gripper 22 in corresponding directions. Finally, the anti-slip pad 23 is brought closer to the can until it is clamped. Then, the electric telescopic rod 15 is activated again, moving the clamped can upwards, thus sterilizing the bottom of the can.

[0028] After sterilization, the sterilized canned goods are placed in the placement slot 4 in the reverse order of the above operations. When sterilizing the canned goods, the placement slot 4, the clamp 22 and other structures can also be sterilized.

[0029] The first motor 5 is started again via the control panel. The first motor 5 will drive the conveyor belt 3 to continue moving, thereby moving the sterilized canned goods to the next process. Through the above operations, the canned goods can be sterilized continuously.

[0030] If the steam in the sterilization chamber 1 is allowed to dissipate on its own, it will be wasteful. Therefore, after sterilization, the vacuum pump 17 is started through the control panel. The vacuum pump 17 will drive the suction pipe 8 to absorb the residual steam inside the sterilization chamber 1 for recycling or other purposes.

[0031] The above steps can thoroughly sterilize canned goods while reducing steam waste.
