Description

Technical Field

[0001] This utility model relates to the field of sandwich series meat product technology, and in particular to a meat product sterilization and preservation device. Background Technology

[0002] In the food processing industry, sterilization and preservation technology for meat products has always been an important research direction. As consumers' demands for food safety and quality continue to rise, traditional technologies are gradually showing their limitations. While high-temperature sterilization can effectively kill microorganisms, it can easily lead to the loss of nutrients and a deterioration in taste. The use of chemical preservatives, although inhibiting microbial growth, poses potential health risks. In recent years, new sterilization and preservation technologies such as ultraviolet sterilization, ozone sterilization, and low-temperature plasma sterilization have gradually emerged. These technologies can, to a certain extent, ensure sterilization effectiveness while better preserving the nutritional components and taste of food. However, their high equipment costs and complex operation still limit large-scale application. To meet market demands, the industry urgently needs a highly efficient, safe, and economical sterilization and preservation technology.

[0003] Currently, the conventional methods for sterilizing and preserving meat products mainly include the following: First, high-temperature sterilization, which kills microorganisms by heating to a certain temperature, but this leads to moisture loss and a decline in taste. Second, the addition of chemical preservatives, such as sodium benzoate and potassium sorbate, to inhibit microbial growth, but this poses food safety risks. Third, vacuum packaging, which inhibits the growth of aerobic bacteria by reducing oxygen content, but has limited effectiveness against some anaerobic bacteria. Fourth, low-temperature refrigeration, which slows down microbial growth by lowering the temperature, but is energy-intensive and cannot completely sterilize. Fifth, ultraviolet sterilization, which kills microorganisms by destroying their DNA structure with short-wave ultraviolet light, but has limited effectiveness for deep sterilization. Sixth, ozone sterilization, which kills microorganisms by releasing highly oxidizing ozone gas, but has high equipment maintenance costs. These methods each have their own characteristics in practical applications and are widely used in the preservation of meat products.

[0004] However, existing technologies have obvious drawbacks: high-temperature sterilization can easily lead to a decline in the quality of meat products, chemical preservatives can be harmful to human health, vacuum packaging has limited sterilization effect on aerobic bacteria, low-temperature refrigeration has high energy consumption and cannot completely sterilize, ultraviolet sterilization has limited effect on deep sterilization, and ozone sterilization equipment has high maintenance costs. Therefore, a meat product sterilization and preservation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a meat product sterilization and preservation device, which aims to improve the limitations of existing sterilization methods, such as high temperature, chemical preservatives, vacuum packaging, low temperature refrigeration, ultraviolet and ozone sterilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] As a further description of the above technical solution:

[0015] The other end of the first connecting rod is rotatably connected to the second connecting rod, and the outside of the second connecting rod is slidably connected to the bottom of the moving plate.

[0020] As a further description of the above technical solution:

[0021] The cleaning mechanism includes a motor, which is externally mounted on the inner wall of the base, and a disc is fixedly connected to the drive end of the motor.

[0022] The above technical solution involves starting the motor, and the positional change of the motor drive end can drive the disk to rotate, thereby providing a clean driving force.

[0023] As a further description of the above technical solution:

[0024] A rotating block is fixedly connected to the outside of the disk, and a limit rod is fixedly connected to the inner wall of the base.

[0025] As a further description of the above technical solution:

[0026] Through the above technical solution: the rotation of the disc drives the rotating block to rotate around the center of the disc, and the base has the function of fixing the position of the limiting rod.

[0027] The limiting rod is slidably connected to a moving rod, the rotating block is slidably connected to the inner wall of the moving rod, the ultraviolet lamp is slidably connected to a cleaning plate, and the moving rod is fixedly connected to the outside of the cleaning plate.

[0032] This utility model has the following beneficial effects:

[0033] 1. In this utility model, the synergistic effect of ultraviolet lamps and ozone generator effectively kills microorganisms on the surface and inside of meat products. The synergistic effect of vacuum pump and gas regulator further inhibits microbial reproduction, extends the shelf life of meat products, avoids the quality decline caused by high-temperature sterilization and the health risks brought by chemical preservatives, and achieves efficient, safe and economical sterilization and preservation effects. When multiple springs deform and reset, they can drive the outside of the sliding plate to make close contact with the contact plate, thereby keeping the inside of the device sealed. The internal sealing of the meat product sterilization and preservation device can prevent external air, dust, microorganisms and other pollutants from entering and avoid secondary contamination of meat products.

[0034] 2. In this utility model, the rotation of the disc drives the rotating block to rotate around the center of the disc, thereby pulling the position of the moving rod to change along the limit rod.

[0042] 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.

[0043] Reference Figure 1 and Figure 3 An embodiment of this utility model provides a meat product sterilization and preservation device, comprising a base 1, an ultraviolet lamp 5 installed on the top of the base 1, an ozone generator 8 installed on the bottom of the base 1, a vacuum pump 2 installed on the outside of the base 1, a gas regulator 6 installed on the side of the base 1 away from the vacuum pump 2, a controller 3 installed on the outside of the base 1, multiple sensors installed on the inner wall of the base 1, a cleaning mechanism 4 installed on the inner wall of the base 1, and a sealing mechanism 7 installed inside the base 1.

[0044] Specifically, the ultraviolet lamp 5 includes a low-pressure mercury lamp or an LED ultraviolet lamp with a wavelength of 253.7nm. Low-pressure mercury lamps have high ultraviolet emission efficiency and are suitable for applications requiring high-intensity ultraviolet sterilization; LED ultraviolet lamps have a longer lifespan and lower energy consumption, making them suitable for scenarios requiring long-term continuous operation. The ozone generator 8 includes a ceramic dielectric discharge ozone generator 8 or an electrolytic water ozone generator 8. The ceramic dielectric discharge ozone generator 8 has high ozone generation efficiency and is suitable for scenarios requiring rapid generation of large amounts of ozone; the electrolytic water ozone generator 8 does not require a high-voltage power supply, offering higher safety and making it suitable for applications with high safety requirements. The vacuum pump 2 includes a rotary vane vacuum pump 2 or a screw vacuum pump 2. The rotary vane vacuum pump 2 has high pumping efficiency and is suitable for scenarios requiring rapid vacuuming; the screw vacuum pump 2 has a longer lifespan and lower noise, making it suitable for scenarios requiring long-term stable operation. The gas regulator 6 includes a proportional gas regulating valve or other types of gas regulating valves. Proportional gas control valves can precisely control gas flow and are suitable for scenarios requiring precise adjustment of gas composition; other types of gas control valves will exhibit better performance in specific situations, such as gas control valves made of materials with stronger corrosion resistance.

[0045] The ultraviolet lamp 5 and the ozone generator 8 work together through the internal space of the device. The ultraviolet light emitted by the ultraviolet lamp 5 effectively kills microorganisms on the surface of meat products, while the ozone generated by the ozone generator 8 penetrates into the meat products to kill deeper microorganisms. This synergistic effect makes the sterilization more comprehensive and thorough. The vacuum pump 2 and the gas regulator 6 also work together through the internal space of the device. After the vacuum pump 2 creates a vacuum, the gas regulator 6 fills the device with inert gas to further inhibit microbial growth and extend the shelf life of the meat products.

[0046] Controller 3 includes a PLC controller 3 or other types of controller 3. The PLC controller 3 has high reliability and stability, and can accurately control the working status of each component based on the temperature, humidity and gas concentration data detected by the sensors. The sensors include temperature and humidity sensors and gas concentration sensors, which are used to monitor the environmental parameters inside the device in real time to ensure that each component operates in optimal condition.

[0047] Reference Figure 4 and Figure 5The sealing mechanism 7 includes a traction door 701, which is rotatably connected to the outer side of the base 1. A contact plate 707 is fixedly connected to the outer side of the traction door 701. A fixing plate 704 is fixedly connected to the inner wall of the base 1. A plurality of springs 705 are fixedly connected to the inner wall of the fixing plate 704. A sliding plate 706 is fixedly connected to the other end of the plurality of springs 705. A telescopic assembly 708 is slidably connected to the inner wall of the base 1.

[0048] Specifically, the positional change of the traction door 701 can cause the contact plate 707 to change position, so that the outside of the contact plate 707 contacts the sliding plate 706, causing the sliding plate 706 to change position, thereby causing multiple springs 705 to deform. The repositioning of the multiple springs 705 can make the outside of the sliding plate 706 in close contact with the outside of the contact plate 707, thereby keeping the inside of the device sealed.

[0049] Reference Figure 3 and Figure 4 The telescopic assembly 708 includes a movable plate 7081, which is slidably connected to the inner wall of the base 1. A connecting rod 7082 is rotatably connected to the bottom of the movable plate 7081. A connecting rod 7083 is rotatably connected to the other end of the connecting rod 7082, and the connecting rod 7083 is slidably connected to the bottom of the movable plate 7081. A connecting rod 7084 is slidably connected to the top of the connecting rod 7083, and the other end of the connecting rod 7084 is rotatably connected to the outside of the traction door 701. A spring 702 is fixedly connected to the inner wall of the base 1, and a locking block 703 is fixedly connected to the other end of the spring 702.

[0050] Specifically, the positional change of connecting rod 1 7082 can pull the moving plate 7081 to move, thereby enabling the moving plate 7081 to move the processed meat product to move. The positional change of connecting rod 2 7083 can pull the positional change of connecting rod 1 7082. The moving plate 7081 provides a sliding space for connecting rod 2 7083, allowing the moving plate 7081 to move a longer distance. The positional change of the traction door 701 can pull the positional change of connecting rod 3 7084, thereby enabling connecting rod 3 7084 to move the positional change of connecting rod 2 7083. The positional change of the locking block 703 can cause the spring 2 702 to deform. The rotation of the locking block 703 can make it engage with the outside of the traction door 701, thereby locking the sealing structure.

[0051] Reference Figure 2The cleaning mechanism 4 includes a motor 401, which is externally mounted on the inner wall of the base 1. A disc 402 is fixedly connected to the drive end of the motor 401. A rotating block 404 is fixedly connected to the outside of the disc 402. A limiting rod 405 is fixedly connected to the inner wall of the base 1. A moving rod 406 is slidably connected to the outside of the limiting rod 405. The rotating block 404 is slidably connected to the inner wall of the moving rod 406. A cleaning plate 403 is slidably connected to the outside of the ultraviolet lamp tube 5. The moving rod 406 is fixedly connected to the outside of the cleaning plate 403.

[0052] Specifically, starting the motor 401 causes the drive end of the motor 401 to rotate, thereby providing a cleaning driving force. The rotation of the disk 402 causes the rotating block 404 to rotate around the center of the disk 402. The base 1 has a fixed position on the outside of the limiting rod 405, so that the moving rod 406 can move along the outside of the limiting rod 405. The position change of the rotating block 404 can cause the moving rod 406 to move. The position change of the moving rod 406 can cause the cleaning plate 403 to slide outside the ultraviolet lamp tube 5, thereby cleaning the outside of the ultraviolet lamp tube 5.

[0053] Working principle: Through the synergistic effect of ultraviolet lamp 5 and ozone generator 8, microorganisms on the surface and inside of meat products are effectively killed. Through the synergistic effect of vacuum pump 2 and gas regulator 6, the reproduction of microorganisms is further inhibited, the shelf life of meat products is extended, and the quality decline caused by high temperature sterilization and the health risks brought by chemical preservatives are avoided, thus achieving efficient, safe and economical sterilization and preservation effects.

[0054] Pushing the traction door 701 causes the contact plate 707 to change position. The outside of the contact plate 707 contacts the sliding plate 706, causing the sliding plate 706 to change position. This causes multiple springs 705 to deform. The reset of the multiple springs 705 causes the outside of the sliding plate 706 to make tight contact with the contact plate 707, thus keeping the inside of the device sealed. Rotating the locking block 703 causes the outside of the locking block 703 to engage with the outside of the traction door 701, and causes the second spring 702 to deform. The reset of the second spring 702 fixes the position of the locking block 703, keeping the inside of the meat product sterilization and preservation device sealed. This prevents external air, dust, microorganisms and other contaminants from entering, avoiding secondary contamination of the meat products.

[0055] When the motor 401 is started, the rotation of the drive end of the motor 401 causes the disc 402 to rotate. The rotation of the disc 402 causes the rotating block 404 to rotate around the center of the disc 402, thereby pulling the position of the moving rod 406 to change along the limit rod 405. The position change of the moving rod 406 causes the cleaning plate 403 to clean the outer surface of the ultraviolet lamp tube 5. Timely cleaning of the exterior of the ultraviolet lamp tube 5 can remove dust, stains and other coverings, thus ensuring the normal intensity of ultraviolet irradiation, ensuring the sterilization effect, allowing the lamp tube to work continuously and stably, avoiding the impact of obstruction on its disinfection efficiency in the target area, and ensuring the smooth and efficient implementation of sterilization work.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
