Description

Technical Field

[0001] This invention belongs to the field of meat processing technology, and in particular relates to a pork processing technology with efficient sterilization and modified atmosphere preservation functions. Background Technology

[0002] In the processing of pork products, improving the preservation quality and extending the shelf life of the products has always been a key focus of the industry. Traditional meat processing technology, while ensuring meat quality, usually relies on refrigeration, the addition of preservatives and other means to extend the shelf life of the products. However, these methods often have some limitations in practical applications. For example, they may have a negative impact on the taste and nutritional value of the meat, as well as pose potential risks to the environment and human health. In addition, the temperature in meat processing workshops is currently 8-10 degrees Celsius to protect meat products and prevent them from being damaged by high temperatures.

[0003] While some technologies and methods currently on the market can extend the shelf life of pork products to a certain extent, they have some significant problems. For example, some preservatives may adversely affect the meat quality, causing it to harden or lose its original flavor. Furthermore, traditional low-temperature preservation methods can only effectively inhibit the growth of microorganisms, but cannot completely eliminate pathogens. In addition, while gas-based packaging technology can improve the preservation of meat products, the technical challenges of establishing and maintaining a stable modified atmosphere storage system still need to be overcome.

[0004] Therefore, there is an urgent need for a device that can efficiently eliminate pathogenic microorganisms in pork products while maintaining the freshness of the meat and achieving a good preservation effect. Summary of the Invention

[0005] This invention addresses the problem that existing low-temperature preservation methods can only effectively inhibit the growth of microorganisms but cannot completely eliminate pathogenic bacteria. The following technical solution is proposed:

A jet pipe is fixedly installed at the bottom of each electric valve.

[0008] As a preferred embodiment of the above technical solution, lifting frames are symmetrically installed on both sides of the outer surface of the guide pipe, and the bottom end of the lifting frame is fixedly connected to the top end of the frame.

[0009] As a preferred embodiment of the above technical solution, a positioning rod is symmetrically welded to one end of the control box, and two round rods are symmetrically rotatably connected between the inner walls of the two positioning rods. A support plate is installed at the position between the two round rods on the opposite side of the two positioning rods. Several cylinders are installed at the top of the control box at the top position of the support plate. Printed blocks are snapped onto the output ends of the cylinders. A rotating rod is symmetrically rotatably connected to one end of the control box, and guide rods are symmetrically installed at equal intervals at the top position of the rotating rod at one end of the control box.

[0010] As a preferred embodiment of the above technical solution, a limit frame is fixedly installed at one end of the control box at the bottom of the positioning rod. A moving block is slidably connected to the outside of the limit frame, and a horizontal rod is movably connected inside the moving block. A protective plate is fixedly installed at one end of the horizontal rod. A cylinder is embedded at the bottom of the two limit frames facing each other. A cylinder is rotatably connected to the top of the frame at the positions on both sides of the control box.

[0011] As a preferred embodiment of the above technical solution, brackets are installed on the top of the frame and on the side of the control box away from the positioning rod. An unwinding roller is rotatably installed inside the bracket located at the top of the frame, and a winding roller is rotatably installed inside the bracket on the side of the control box.

[0012] As a preferred embodiment of the above technical solution, a base plate is fixedly installed inside the frame at the position between the conveyor belts. A cylinder three is fixedly installed at the top of the base plate. A limit strip is fixedly installed between the tops of two cylinders three. Four limit blocks are equidistantly installed at the top of the limit strip. Lifting blocks are movably connected to the inside of each of the four limit blocks. A vibration motor is fixedly installed at the middle of the top of each lifting block. A vibration head is fixedly installed at the output end of the vibration motor.

[0013] As a preferred embodiment of the above technical solution, the bottom end of the lifting block is connected to a linkage rope that passes through the limiting block, and one end of the linkage rope is equipped with a clamping plate that is slidably connected inside the limiting block. A spring rod is snapped between the clamping plate and the opposite surface of the limiting block.

[0014] As a preferred embodiment of the above technical solution, a serrated strip is welded to the top of the base plate, and a gear that is rotatably connected to the limit block is engaged with the edge of the serrated strip. An L-shaped rack is connected to the outer core of the gear, and one end of the L-shaped rack is fixedly connected to one end of the lifting block.

[0015] A pork processing technology with efficient sterilization and modified atmosphere preservation functions includes the following steps;

[0016] Step 1: Place the ingredients: Put the pork into the food storage container;

[0017] Step 2: Vibration Smoothing: The vibration of the motor during operation moves the pork inside the food storage container.

[0018] Step 3: Gas protection: Gas is generated by an ozone generator, and external CO2 and O3 enter the gas mixer for mixing. The mixed gas enters the gas mixing cylinder through the pipeline for blending. The gas ratio and concentration in the gas mixing cylinder are detected by a gas detector. The O3 concentration can be adjusted by the gas flow rate. The blended gas is sprayed into the inside of the food storage container through the jet pipe.

[0019] Step 4: Film application: The protective film is cut, heat-pressed, and squeezed using a cutting board, cutting knife, heat-sealing plate, and pressing plate to adhere it to the top of the food storage container.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) Using O3 as a high oxidant can effectively kill bacteria on the surface of pork, especially Clostridium botulinum (an anaerobic bacterium). Clostridium botulinum is a single-celled organism and can be fully killed under the action of O3. Clostridium botulinum cannot survive in a high-oxygen environment, while pork cells are multicellular clusters that exchange energy and nutrients, achieving mutual protection. Therefore, pork cells have a stronger survival ability under high O3 concentrations. We need to calculate the appropriate O3 concentration to ensure effective bacterial killing without harming the survival of normal pork cells. Calculations show that O3 concentrations of 20-30 mg / L can effectively kill bacteria without damaging pork cells, ensuring higher quality and better safety for pork. Therefore, it can effectively improve the preservation effect and food safety of pork. O3 has a long half-life at low temperatures (0-10 degrees Celsius), exceeding 120 minutes, which allows for mixing, gas filling, packaging, and sufficient time to kill bacteria. Therefore, using O3 for modified atmosphere packaging is feasible and effective. Using O3 modified atmosphere packaging technology to preserve pork can extend the preservation time by more than 2 days compared to existing modified atmosphere packaging technologies.

[0022] (2) Vibration drives the pork inside the food storage box to disperse, thereby keeping the top of the pork flat. This method helps to ensure that the pork is more evenly distributed during storage and transportation, thus ensuring the quality and safety of the food. It also helps to cover the surface of the food storage box with film later, preventing pork residue from remaining at the seam between the film and the food storage box during the film covering process, thereby improving the subsequent connection effect.

[0023] (3) It can clamp the food storage container, keep the food storage container stable, prevent the food storage container from shifting during vibration, and further improve the vibration dispersion effect.

[0024] (4) The date labeling process has been automated, reducing the cost of manual operation and improving work efficiency.

[0025] (5) It can limit the installation of the protective film, ensuring that its layout is neat and its fixation is reliable, which helps the protective film to be laid out and fixed smoothly, reduces wrinkles caused by movement or use, and improves the subsequent use effect.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0034] Example 1

[0035] This invention provides a pork processing technology with highly efficient sterilization and modified atmosphere storage functions, such as... Figures 1 to 6 As shown, the pork processing device includes: a frame 1, a conveyor belt 2 installed inside the frame 1, a control box 3 fixedly installed at the top of the frame 1, a number of cylinders 27 equidistantly installed at the bottom of the control box 3, a pressing plate 28 installed between the bottom ends of two cylinders 27, and a total of four pressing plates 28. A cutting plate 29 is movably installed at the bottom end of the leftmost pressing plate 28, a cutting blade 30 is movably installed at the bottom end of the second pressing plate 28 from left to right, a heat sealing plate 31 is movably installed at the bottom end of the third pressing plate 28 from left to right, and a pressing plate 32 is movably installed at the bottom end of the rightmost pressing plate 28.

[0036] An ozone generator 20 is installed on the back of the frame 1. After the ozone generator 20 is connected to a pure oxygen generator, O3 is generated through the ozone generator 20 and the pure oxygen generator during use. Two pipes are connected to the bottom of the gas mixer 21; one pipe is connected to the outlet of the ozone generator 20, and the other pipe is connected to a CO2 gas pipe. At this time, O3 and CO2 are input into the gas mixing cylinder 22 through the gas mixer 21. The outlet of the gas mixer 21 is connected to the gas mixing cylinder 22 through a pipe. The gas mixing cylinder 22 has three inlets, allowing different gases to enter. Therefore, the gas mixture in the gas mixing cylinder 22 contains CO2, O2, and O3. In this application, CO2 and O3 are used for gas regulation. The gas mixing cylinder 22 is equipped with a gas monitor 46 connected to one end. The gas monitor 46 monitors the gas inside the gas mixing cylinder 22 and only injects the gas into the gas mixing cylinder 22 after the target ratio is reached. The gas outlet of the gas mixing cylinder 22 is connected to a guide pipe 23 through a pipeline. Four electric valves 24 are installed at equal intervals on the outside of the guide pipe 23. A jet pipe 25 is fixedly installed at the bottom of the electric valve 24. The temperature of the production line is between 8-10 degrees Celsius. At this temperature, it is used to protect the pork and prevent the pork from being damaged by high temperature and becoming smelly. Gas regulating valves are set on the outside of the connection points of the pipeline to the ozone generator 20, the gas mixer 21 and the gas mixing cylinder 22 respectively, which are used to regulate the flow rate of the gas entering the pipeline.

[0037] like Figure 1 and Figure 2 As shown, lifting frames 26 are symmetrically installed on both sides of the outer surface of the guide pipe 23, and the bottom end of the lifting frame 26 is fixedly connected to the top end of the frame 1.

[0038] The lifting frame 26 facilitates the lifting and lowering of the guide pipe 23, thus reducing the difficulty of lifting and lowering the guide pipe 23.

[0039] like Figure 1 and Figure 3 As shown, a positioning rod 4 is symmetrically welded to one end of the control box 3. Two round rods 5 are symmetrically rotatably connected between the inner walls of the two positioning rods 4. A support plate 6 is installed between the two positioning rods 4 and the two round rods 5. Several cylinders 7 are installed at the top of the control box 3 at the top of the support plate 6. Printing blocks 8 are snapped onto the output ends of the cylinders 7. The number of cylinders 7 and printing blocks 8 is set to four. A rotating rod 9 is symmetrically rotatably connected to one end of the control box 3. The back of the rotating rod 9 is connected to the output shaft of the drive motor fixedly installed in the control box 3 by a flat key for the rotation of the rotating rod 9. Two rollers are rotatably connected to the outside of the rotating rod 9. A thermal printing film is fixedly installed on the outside of one roller, and the used thermal printing film is wound on the outside of the other roller. Guide rods 10 are symmetrically installed at equal intervals at the top of the rotating rod 9 at one end of the control box 3.

[0040] The roller rotates under the action of the rotating rod 9. At this time, another rotating rod 9 is installed on the outside of the roller. The thermal printing film enters the outside of the guide rod 10 at the bottom of the rotating rod 9 and enters the outside of the roller. At this time, the cylinder 7 is activated. When the cylinder 7 moves, it drives the printing block 8 to move. When the printing block 8 moves, it drives the thermal printing film to continue printing on the plastic wrap, so that the date appears on the plastic wrap. This method automates the date marking, saves labor costs, and improves work efficiency.

[0041] like Figure 1 and Figure 3 As shown, a limit frame 11 is fixedly installed at one end of the control box 3 at the bottom of the positioning rod 4. A moving block 12 is slidably connected to the outside of the limit frame 11. A horizontal rod 14 is horizontally connected inside the moving block 12. A protective plate 15 is fixedly installed at one end of the horizontal rod 14. A cylinder 16 is embedded at the bottom of the two limit frames 11 facing each other. A cylinder 2 17 is rotatably connected to the top of the frame 1 at the positions on both sides of the control box 3.

[0042] The position of the protective plate 15 can be changed by the up-and-down moving block 12. Then, the protective plate 15 is moved so that it enters the edge of the protective film, thereby limiting the protective film to the left and right. Then, the limited protective film is moved along the bottom of cylinder 16 and cylinder 27 to limit the position of the protective film. At this time, the protective film is at the top of the food storage box, which makes it easier to fix the food storage film to the surface of the food storage box later.

[0043] like Figure 2 and Figure 3 As shown, brackets 18 are installed at the top of the frame 1 and on the side of the control box 3 away from the positioning rod 4. A motor is installed at one end of the bracket 18. The output ends of the two motors are connected to the unwinding roller 13 and the winding roller 19 respectively through flat keys for the rotation of the unwinding roller 13 and the winding roller 19, thereby changing the difficulty of the rotation of the unwinding roller 13 and the winding roller 19. The unwinding roller 13 is rotatably installed inside the bracket 18 located at the top of the frame 1, and the winding roller 19 is rotatably installed inside the bracket 18 on the side of the control box 3.

[0044] The take-up roller 19 and the unwind roller 13 can be placed on the bracket 18, and the protective film is unwound by the unwind roller 13. The unwound protective film enters the outside of the take-up roller 19, thereby winding up the protective film and allowing it to flow.

[0045] like Figure 5 and Figure 6As shown, a base plate 33 is fixedly installed inside the frame 1 at the position between the conveyor belts 2. A cylinder 35 is fixedly installed on the top of the base plate 33. A limit strip 36 is fixedly installed between the tops of the two cylinders 35. Four limit blocks 37 are equidistantly installed on the top of the limit strip 36. Lifting blocks 41 are movably connected to the inside of each of the four limit blocks 37. A vibration motor 44 is fixedly installed in the middle of the top of the lifting block 41. A vibration head 45 is fixedly installed at the output end of the vibration motor 44.

[0046] It can easily clamp the food storage container and cause the inside of the container to vibrate, thereby moving the pork inside the container and using the vibration force to keep the pork at the top of the container flat.

[0047] like Figure 5 and Figure 6 As shown, the bottom end of the lifting block 41 is connected to a linkage rope 40 that passes through the limiting block 37. One end of the linkage rope 40 is equipped with a clamping plate 38 that is slidably connected inside the limiting block 37. A spring rod 39 is snapped between the clamping plate 38 and the opposite surface of the limiting block 37.

[0048] As the lifting block 41 rises, the clamping plate 38 moves via the linkage rope 40. When the clamping plate 38 moves, it compresses the spring rod 39, thus clamping the food storage container and keeping it stable. At the same time, the clamping plate 38 is driven to reset under the tension of the spring rod 39, which facilitates the separation between the clamping plate 38 and the food storage container.

[0049] like Figure 5 and Figure 6 As shown, a serrated strip 34 is welded to the top of the base plate 33. A gear 43 is meshed with the edge of the serrated strip 34 and rotatedly connected to the limit block 37. An L-shaped rack 42 is connected to the outer core of the gear 43, and one end of the L-shaped rack 42 is fixedly connected to one end of the lifting block 41.

[0050] As the limiting strip 36 rises and falls, it drives the gear 43 to rise and fall. When the gear 43 rises and falls, it rotates under the action of the serrated strip 34. When the gear 43 rotates, it drives the L-shaped rack 42 to move. When the L-shaped rack 42 moves, it drives the lifting block 41 to rise and fall, which changes the difficulty of the lifting block 41. This makes the vibrating head 45 at the top of the lifting block 41 contact the bottom of the food storage box, which makes it easier to keep the inside of the food storage box vibrating. The vibration drives the pork inside the food storage box to disperse, so that the top of the pork remains flat.

[0051] A pork processing technology with efficient sterilization and modified atmosphere preservation functions includes the following steps;

[0052] Step 1: Place the ingredients: Put the pork into the food storage container;

[0053] Step 2: Vibration Smoothing: The vibration of the vibrating motor 44 during operation causes the pork inside the food storage container to move.

[0054] Step 3: Gas Protection: Gas is generated by ozone generator 20, and external CO2 and O3 enter the gas mixer 21 for mixing. The mixed gas then enters the gas mixing cylinder 22 for further preparation. The gas ratio and concentration in the gas mixing cylinder 22 are detected by gas detector 46. The O3 concentration can be adjusted by the gas flow rate. The prepared gas is then sprayed into the inside of the preservation box along the jet pipe 25, thus protecting the pork inside the preservation box with gas.

[0055] Step 4: Film application: The protective film is cut, hot-pressed, and squeezed using the cutting plate 29, cutting knife 30, heat-sealing plate 31, and pressing plate 32 to adhere the protective film to the top of the food storage container.

[0056] Working principle: In actual use, the operator moves the protective film of the unwinding roller 13 along the outside of the two round rods 5 to the outside of the first cylinder 16, and then along the first cylinder 16 to the outside of the two second cylinders 17, and then along the outside of the second cylinder 17 to the outside of the take-up roller 19. At this time, the protective film is laid out. Then, the operator pushes the moving block 12. When the moving block 12 moves, it drives the position of the horizontal rod 14 to move. Then, the horizontal rod 14 moves, so that the horizontal rod 14 drives the protective plate 15 to the outside of the protective film, thereby limiting the installation of the protective film, ensuring that its layout is neat and its fixation is reliable. This helps to smoothly lay and fix the protective film, reduce wrinkles caused by movement or use, and improve the subsequent use effect.

[0057] Next, the roller rotates under the action of the rotating rod 9. At this time, another rotating rod 9 is installed on the outside of the roller. The thermal printing film enters the outside of the guide rod 10 at the bottom of the rotating rod 9 and enters the outside of the roller. At this time, the cylinder 7 is activated. When the cylinder 7 moves, it drives the printing block 8 to move. When the printing block 8 moves, it drives the thermal printing film to continue printing on the plastic wrap. This method realizes the automated date marking process, reduces the cost of manual operation, and also improves work efficiency.

[0058] Next, the personnel place the food storage container containing pork into the conveyor belt 2. The conveyor belt 2 then moves, and when it reaches the top of the bottom plate 33, the conveyor belt 2 stops. Then, cylinder 35 is activated. Cylinder 35 moves the limit bar 36, which in turn moves the limit block 37. The rise and fall of the limit block 37 causes the gear 43 to rise. As the gear 43 rises, it rotates under the action of the serrated rack 34. This rotation of the gear 43 causes the L-shaped rack 42 to rise. The movement of the L-shaped rack 42 then causes the lifting block 41 to rise. The lifting block 41 rises, driving the vibration motor 44 to rise. When the vibration motor 44 rises, the vibration head 45 at the top of the lifting block 41 contacts the bottom of the food storage box, which facilitates the vibration inside the food storage box. The vibration drives the pork inside the food storage box to disperse, thus keeping the top of the pork flat. This method helps to ensure that the pork is more evenly distributed during storage and transportation, thereby ensuring the quality and safety of food. It also helps to cover the surface of the food storage box with film later, preventing pork residue from remaining at the seam between the film and the food storage box during the film covering process, thereby improving the subsequent connection effect.

[0059] Furthermore, during this process, as the lifting block 41 rises, the clamping plate 38 moves via the linkage rope 40. When the clamping plate 38 moves, it compresses the spring rod 39. The clamping plate 38 clamps the food storage container, keeping it stable and preventing displacement during vibration, thus further improving the vibration dispersion effect.

[0060] Next, conveyor belt 2 continues to move the food storage container, causing it to enter the bottom of the jet pipe 25. At this time, ozone generator 20 operates to produce O3. CO2 and O3 enter the gas mixer 21 and mix. The mixed gas then enters the gas mixing cylinder 22, where O3 and CO2 are blended. The gas monitor 45 monitors the gas, and once the target ratio is reached, the gas flows along guide pipe 23 into electric valve 24. Electric valve 24 then opens and closes, allowing the mixed gas to flow along jet pipe 25 into the food storage container. The temperature of this production line is between 8-10 degrees Celsius, at which point the decomposition rate of O3 is relatively slow, thus increasing the residual time of O3. Using O3 as a high oxidant, it can also effectively kill bacteria on the surface of pork, especially Clostridium botulinum (anaerobic bacteria). Since the cells are single-celled organisms, under the action of the high oxidant O3, they can be fully eliminated. Clostridium botulinum is an anaerobic bacterium that cannot survive in a high-oxygen environment. Pork cells, on the other hand, are multicellular clusters that exchange energy and nutrients with each other for mutual protection. Therefore, pork cells have a stronger survival ability under high concentrations of O3. In order to ensure effective killing of bacteria without harming the survival of normal pork cells, it has been calculated that an O3 concentration of 20-30 mg / L can effectively kill bacteria without damaging pork cells, ensuring higher quality and better safety of pork. Therefore, it can effectively improve the preservation effect and food safety of pork. O3 has a long half-life at low temperatures (0-10 degrees Celsius), exceeding 120 minutes, which allows for mixing, gas filling, packaging, and sufficient time for killing bacteria. Therefore, using O3 for modified atmosphere packaging is feasible and effective. Using O3 modified atmosphere packaging technology to preserve pork can extend the shelf life by more than 2 days compared to existing modified atmosphere packaging technologies.

[0061] Next, the food storage container containing O3 gas is placed at the bottom of the cutting plate 29. At this time, cylinder 27 drives the pressing plate 28 to move. When the pressing plate 28 moves, it drives the cutting plate 29 to the top of the food storage container. At this time, the outer ring of the plastic wrap is cut. Simultaneously, cylinder 27 drives the pressing plate 28 to move. When the pressing plate 28 moves, it drives the cutting blade 30 to make a horizontal cut on the protective film. Then it resets. Then, the plastic wrap and the food storage container are simultaneously placed at the bottom of the heat sealing plate 31. At this time, the heat sealing plate 31 moves up and down to heat and press the plastic wrap. Then it resets. Then, the plastic wrap and the food storage container are simultaneously placed at the bottom of the pressing plate 32. At this time, the pressing plate 32 moves up and down to press the plastic wrap, so that the plastic wrap covers the outside of the food storage container, thereby protecting the pork inside the food storage container.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
