Description

Technical Field

[0001] This invention relates to the field of canned food sterilization technology, and in particular to a canned food sterilization device, sterilization equipment, and sterilization method. Background Technology

[0002] Sterilization of canned foods is done to extend their shelf life and ensure food safety. The following are common sterilization methods for canned foods:

[0003] High-temperature sterilization (heat sterilization): This is one of the most common sterilization methods. Food is heated to a high temperature in a sealed container, usually between 120 and 135 degrees Celsius, for a period of time (usually a few minutes to tens of minutes) to ensure that microorganisms in the food, including bacteria, fungi, and spores, are killed.

[0004] When sterilizing canned foods, it is necessary to select an appropriate sterilization method based on the nature of the food, its packaging form, and production requirements, and to ensure that the sterilization process complies with hygiene standards and food safety regulations.

[0005] During the sterilization process of canned foods, gases such as oxygen from the air and air bubbles from the food may be released. These gases expand in a high-temperature environment, causing the pressure inside the can to increase, which in turn causes the lid to bulge and result in food leakage.

[0006] In summary, the existing technology lacks a technique to prevent can lids from bulging during high-temperature sterilization of certain canned foods. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art by providing a sterilization device, sterilization equipment, and sterilization method for canned food.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a canned food sterilization device, including a sterilization pot, a placement rack is slidably arranged inside the sterilization pot, a plurality of placement mesh plates are fixedly connected to the placement rack, a plurality of cans are placed on the placement mesh plates, a plurality of fixing frames are fixedly connected to the placement mesh plates, and a plurality of anti-bulging lid mechanisms are fixedly connected to the fixing frames.

[0009] A cleaning box is fixedly installed on one side of the sterilizer. An adjusting seat is slidably fitted inside the cleaning box. A cleaning mechanism is rotatably connected to the adjusting seat. The anti-bulging cover mechanism includes an electric push rod A. One end of the electric push rod A is fixedly connected to a fixed frame, and the other end of the electric push rod A is fixedly connected to an adjusting frame. An electric push rod B is fixedly connected inside the adjusting frame, and a pressure plate is fixedly connected to the other end of the electric push rod B. Sliding sliders are slidably fitted on the inner walls of both ends of the adjusting frame. A spring is fixedly connected between the sliding slider and the adjusting frame. A clamping plate is fixedly connected to the bottom end of the sliding slider. An inclined guide block is fixedly connected to one end of the sliding slider. Guide pressure rods are fixedly connected to both ends of the pressure plate, and the guide pressure rods slide in contact with the inclined guide blocks. A sliding sleeve is fixedly connected to the bottom of the placement rack. A limit frame is fixedly connected inside the sterilizer, and the sliding sleeve slides in contact with the limit frame. The cleaning mechanism includes an elbow pipe, which is fixedly connected to an adjusting seat. One end of the elbow pipe is connected to a pipe connector via a flexible hose, and the other end of the pipe connector is fixedly connected to the cleaning tank. A rinsing pipe is rotatably connected to the other end of the pipe connector. A worm gear is fixedly connected to one end of the rinsing pipe, and a worm is engaged with one side of the worm gear. The worm is rotatably connected to the adjusting seat, and an adjusting wheel is fixedly connected to one end of the worm. A sealing cover is slidably fitted at one opening of the cleaning tank, and a pressure rod is rotatably connected to one end of the sealing cover. The other end of the pressure rod is threadedly connected to the cleaning tank. A limit seat is fixedly connected inside the cleaning tank, and the limit seat is slidably fitted with a sliding sleeve. A rack is fixedly connected to one inner wall of the cleaning tank, and the rack is engaged with the adjusting wheel. A drain pipe is fixedly connected to the bottom of the cleaning tank.

[0010] Preferably, the placement mesh plate is fixedly provided with multiple dividing strips.

[0011] Preferably, the adjusting seat is threadedly connected to a threaded rod, one end of which passes through the inner wall of the cleaning tank, extends to the outside, and is fixedly connected to a motor.

[0012] It is also proposed that a method for sterilizing canned food, using the aforementioned apparatus, includes the following steps:

[0013] S1. By placing the sliding sleeve at the bottom of the placement rack onto the limiting frame, place it into the sterilizer, and then place the canned goods onto the placement mesh plate in sequence.

[0014] S2. Then, use the electric push rod B to move the pressure plate down and press it on the top of the can to prevent air from bulging inside the can during high-temperature sterilization, which would cause air leakage at the can opening.

[0015] S3. Then turn off the sterilizer and sterilize the canned food with high temperature. After sterilization, the canned food needs to be removed. At this time, use electric push rod A to move the adjusting frame up, thereby moving the can held by the clamping plate up. Then insert the material picking plate between the can and the placing mesh plate, and then move the clamping plate apart, so that the can falls onto the material picking plate to complete the quick material picking.

[0016] S4. Then take out the used placement rack and place it in the cleaning tank. Then close the sealing cover and move the adjusting seat by driving the threaded rod. At this time, under the action of the rack, the rinsing pipe will rotate and be placed between multiple placement mesh plates.

[0017] S5. Then, the external cleaning fluid is injected into the hose through the pipe joint via the pump body, and then injected into the flushing pipe through the elbow pipe to flush the mesh plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When high-temperature sterilization of canned goods is required, the anti-bulging lid mechanism is used so that the pressure plate can press against the lid of the can, thereby preventing the lid from bulging during sterilization and avoiding food leakage.

[0020] 2. When removing sterilized canned goods, the clamps in the anti-bulging lid mechanism can lift the cans, making it easier to insert them into the material receiving plate. When the clamps are released, multiple cans can fall onto the material receiving plate at once, achieving rapid unloading.

[0021] 3. By using the cleaning mechanism, after the canned food is sterilized, the racks and other structures are placed in the cleaning box. Under the action of the adjusting seat, the rinsing pipe can automatically rinse the racks and other structures, which helps to remove residual food fragments, grease, bacteria and other dirt, and prevent dirt residue from causing cross-contamination of food and safety issues.

Both ends of the adjusting frame 602 have slidably fitted inner walls. A slider 605 is provided, and a spring 606 is fixedly connected between the slider 605 and the adjusting frame 602. A clamping plate 607 is fixedly connected to the bottom of the slider 605. An inclined guide block 608 is fixedly connected to one end of the slider 605. Guide pressure rods 609 are fixedly connected to both ends of the pressure plate 604. The guide pressure rods 609 and the inclined guide block 608 are in sliding contact. A sliding sleeve 201 is fixedly connected to the bottom of the placement frame 2. A limit frame 101 is fixedly connected to the inside of the sterilizer 1. The sliding sleeve 201 and the limit frame 101 are in sliding cooperation. The cleaning mechanism 9 includes an elbow pipe 901, which is fixedly connected to the adjusting seat 8. One end of the elbow pipe 901 is connected to a pipe connector 902 via a hose 907. The other end of the pipe connector 902 is fixedly connected to the cleaning tank 7. A rinsing pipe 903 is rotatably connected to the other end of the pipe connector 902. A worm gear 904 is fixedly connected to one end of the rinsing pipe 903. A worm 905 is meshed and driven on one side of the worm gear 904. The worm 905 is rotatably connected to the adjusting seat 8. One end of the worm 905 is fixedly connected to... An adjusting wheel 906 is provided. A sealing cover 701 is slidably fitted at the opening on one side of the cleaning tank 7. A pressure rod 705 is rotatably connected to one end of the sealing cover 701, and the other end of the pressure rod 705 is threadedly connected to the cleaning tank 7.

A rack 703 is fixedly connected to the inner wall of one side of the cleaning tank 7, and the rack 703 is engaged with the adjusting wheel 906 for transmission. A drain pipe 704 is fixedly connected through the bottom of the cleaning tank 7. The sterilizer 1 is a steam-type high-temperature sterilizer 1: it uses steam as a heat transfer medium to heat canned food to a high temperature through direct steam heating to achieve sterilization.

[0034] like Figure 4 As shown, multiple separator strips 301 are fixedly installed on the mesh plate 3. The separator strips 301 facilitate the separation of the cans 4.

[0035] like Figure 7 As shown, a threaded rod 801 is threadedly connected to the adjusting seat 8. One end of the threaded rod 801 extends through the inner wall of the cleaning tank 7 to the outside and is fixedly connected to a motor 802. The threaded rod 801 drives the cleaning mechanism 9 to move.

[0036] A method for sterilizing canned food, using the aforementioned apparatus, includes the following steps:

[0037] S1. By placing the sliding sleeve 201 at the bottom of the placement rack 2 onto the limiting rack 101, the rack is placed into the sterilizer 1, and then the canned food 4 is placed onto the placement mesh plate 3 in sequence.

[0038] S2. Then, use the electric push rod B603 to drive the pressure plate 604 to move down and press it on the top of the can 4 to prevent air from bulging inside the can 4 during high-temperature sterilization, which would cause air leakage at the opening of the can 4.

[0039] S3. Then shut down the sterilizer 1 and sterilize the can 4 with high temperature. After sterilization, the can 4 needs to be removed. At this time, use the electric push rod A601 to drive the adjusting frame 602 to move upward, thereby driving the can 4 held by the clamping plate 607 to move upward. Then insert the material picking plate between the can 4 and the placing mesh plate 3, and then drive the clamping plate 607 to separate, so that the can 4 falls onto the material picking plate, completing the rapid material picking.

[0040] S4. Then take out the used placement rack 2 and place it in the cleaning box 7. Then close the sealing cover 701. By causing the threaded rod 801 to drive the adjusting seat 8 to move, the rinsing pipe 903 will rotate and be placed between multiple placement mesh plates 3 under the action of the rack 703.

[0041] S5. Then, the external cleaning fluid is injected into the hose 907 through the pipe joint 902 by the pump body, and then injected into the flushing pipe 903 through the elbow pipe 901, thereby flushing the mesh plate 3.

[0042] By placing the sliding sleeve 201 at the bottom of the placement rack 2 onto the limiting rack 101, the rack is placed into the sterilizer 1. Then, the cans 4 are placed on the placement mesh plate 3 in sequence. Then, the electric push rod A601 is used to drive the adjusting rack 602 to move down to the appropriate position.

[0043] The electric actuator B603 drives the pressure plate 604 to move down and press it on the top of the can 4, so as to prevent air from bulging inside the can 4 during high-temperature sterilization and causing air leakage at the opening of the can 4. At the same time, when the pressure plate 604 moves down, it will contact the inclined guide block 608 through the guide rod 609, thereby driving the connected slider 605 to move, so that the slider 605 drives the connected clamping plate 607 to clamp the can 4.

[0044] Then, the sterilizer 1 is turned off, and the can 4 is sterilized by high temperature. After sterilization, the can 4 needs to be removed. At this time, the electric push rod A601 drives the adjusting frame 602 to move upward, thereby driving the can 4 held by the clamping plate 607 to move upward. Then, the material picking plate is inserted between the can 4 and the placing mesh plate 3. Then, the electric push rod B603 drives the pressure plate 604 to move upward. At this time, the inclined guide block 608 is unrestricted. Under the action of the spring 606, the clamping plate 607 is separated, so that the can 4 falls onto the material picking plate, completing the rapid material picking.

[0045] Then, the used placement rack 2 is taken out and placed in the cleaning tank 7. Then, the sealing cover 701 is closed, and the pressure rod 705 is rotated to connect it to the cleaning tank 7. Then, the motor 802 drives the threaded rod 801 to rotate, so that the threaded rod 801 drives the adjusting seat 8 to move. At this time, under the action of the rack 703, the worm 905 connected to the adjusting wheel 906 will rotate, so that the worm 905 drives the flushing pipe 903 connected to the worm wheel 904 to rotate and be placed between multiple placement mesh plates 3.

[0046] Then, the external cleaning fluid is injected into the hose 907 through the pipe joint 902 via the pump body, and then into the flushing pipe 903 through the elbow pipe 901, thereby flushing the mesh plate 3.
