Description

Technical Field

[0001] This invention relates to the technical field of food production and processing, specifically to a sterilization method and sterilization apparatus for processing cooked meat products. Background Technology

[0002] In the cooked meat processing industry, sterilization is a core process to ensure food safety and extend shelf life. Among them, water bath sterilization is widely used in the processing and production of various cooked meat products because it is gentle and can better preserve the taste and quality of cooked meat products.

[0003] Currently, there are various types of water bath sterilization devices for cooked meat products on the market, covering small manual, medium semi-automatic, and large-scale assembly line types. These devices are widely used in the processing and production of various cooked meat products such as braised meat, vacuum-packed ham, and soy-braised meat products. The core working principle of these devices is to place the cooked meat products in a hot water environment at a certain temperature and keep them warm for a period of time. This kills any residual harmful microorganisms, bacteria, and spores in the meat products, thereby achieving the desired sterilization effect, ensuring the food safety of cooked meat products, and extending the product's shelf life.

[0004] Most existing sterilization devices use hot water in a single-use mode. After sterilizing a batch of cooked meat products, the hot water used for sterilization is directly discharged because it contains a small amount of meat scraps, grease, seasoning residues and other impurities. It cannot be reused for subsequent sterilization operations, resulting in a serious waste of water resources and heat energy, and significantly increasing processing costs.

[0005] Meanwhile, most existing sterilization devices adopt a single sterilization chamber structure, which requires the material-carrying structure to be removed and the sterilized material taken out after one sterilization operation is completed, and then the cooked meat products to be sterilized are put back in. The feeding, sterilization and discharging cannot be carried out synchronously and alternately, resulting in long waiting time. Summary of the Invention

[0030] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0031] like Figures 1 to 9 As shown, a sterilization device for processing cooked meat products includes a base 1 and a sterilization tank 2, wherein the sterilization tank 2 is rotatably connected to the base 1; the sterilization tank 2 has a sterilization chamber 3 and a filtration chamber 4 inside, and the filtration chamber 4 is connected to the sterilization chamber 3; there are two sterilization chambers 3, which are symmetrically distributed and located at the top and bottom of the filtration chamber 4 respectively. Through the rotational connection between the sterilization tank 2 and the base 1, the two sterilization chambers 3 can be alternately switched to the feeding station (top of the sterilization tank 2) and the sterilization station (bottom of the sterilization tank 2). Sterilization, feeding, and discharging can be carried out simultaneously without waiting for a single sterilization chamber 2 to complete the entire process, which greatly shortens the operation waiting time. Through this alternating operation mode, the problem of low efficiency in existing devices with a single sterilization chamber 2, which requires waiting for a single sterilization to be completed before feeding is achieved, is solved.

[0032] Each sterilization chamber 3 is equipped with a sterilization mechanism 5 and a material loading mechanism 6. The filtration chamber 4 is equipped with a filtration mechanism 7, which is used for filtering and recirculating the sterilization hot water. The filtration mechanism 7 is responsible for filtering impurities from the circulating hot water to prevent impurities from affecting the sterilization effect and the service life of the equipment. The sterilization mechanism 5 includes a heating component 8, which provides a constant temperature for the sterilization process, ensuring that the cooked meat products achieve the expected sterilization effect.

[0033] During the sterilization process, the hot water retained in one sterilization chamber 3 is filtered by the filtration mechanism 7 to remove impurities and can then flow directly into another sterilization chamber 3 to be sterilized for pre-filling. This not only avoids the waste caused by direct discharge of hot water and reduces processing costs, but also avoids the frequent start-stop of the heating component 8 by pre-filling with hot water, further saving energy.

[0034] The material loading mechanism 6 includes a material loading frame 9 and a cover plate 10. The material loading frame 9 slides in conjunction with the sterilization chamber 3 along the axial direction of the sterilization tank 2. Multiple material loading frames 9 are provided and stacked in the vertical direction. The cover plate 10 covers the material loading frame 9 that is furthest from the filter chamber 4.

[0035] In use, the operator first places the cooked meat products to be sterilized one by one into each of the loading frames 9. After the placement is completed, the cover plate 10 is closed. Then, the loading frames 9 containing the cooked meat products to be sterilized are pushed along the axis of the sterilization tank 2 into the sterilization chamber 3 located at the top of the sterilization tank 2 to complete the loading preparation.

[0036] Next, the sterilization tank 2 is rotated. At this time, the sterilization chamber 3 containing the cooked meat products to be sterilized gradually rotates towards the bottom of the sterilization tank 2. Meanwhile, the hot water remaining in another sterilization chamber 3 will pass through the filter chamber 4 and the internal filter mechanism 7 to filter impurities and then flow into the rotating sterilization chamber 3 to achieve pre-filling of hot water and avoid the impact of sudden temperature changes in the early stage of sterilization on the quality of cooked meat products.

[0037] When the sterilization chamber 3 containing the cooked meat products to be sterilized is fully rotated to the bottom of the sterilization tank 2, the heating component 8 in the sterilization mechanism 5 heats the hot water in the chamber and maintains the temperature within the constant range required for sterilization. This hot water immersion method ensures thorough sterilization of the cooked meat products, killing harmful microorganisms and guaranteeing food safety. Simultaneously, the operator removes the loading frame 9 from the sterilization chamber 3 at the top of the sterilization tank 2, takes out the sterilized cooked meat products, and quickly places in new cooked meat products to be sterilized. This continuous cycle of loading, sterilization, and unloading significantly improves operational efficiency.

[0038] The interconnected design of multiple sterilization chambers 3 and filtration chambers 4 enables the recycling of hot water. After being filtered by the filtration mechanism 7, the hot water can be reused in subsequent sterilization operations, effectively reducing the waste of water resources and heat energy and lowering processing costs. At the same time, the hot water pre-filling operation avoids the frequent start-up and shutdown of the heating component 8, further saving energy and improving the economy and environmental friendliness of the equipment.

[0039] By rotating and cooperating with two symmetrically distributed sterilization chambers 3 and sterilization tank 2, the alternation of feeding and sterilization is realized. There is no need to wait for a single sterilization chamber 3 to complete the entire process before feeding. Combined with the step-by-step operation method, the waiting time is effectively shortened. At the same time, the stacked arrangement of multiple material loading frames 9 further increases the batch size of a single sterilization, taking into account both efficiency and batch requirements, and is suitable for large-scale cooked meat product processing scenarios.

[0040] According to one embodiment of the present invention, the filtration mechanism 7 includes a partition 11, a filter basket 12, and a filter frame 13; two partitions 11 and two filter baskets 12 are provided, and the two partitions 11 are respectively fixedly disposed between the corresponding sterilization chamber 3 and the filter chamber 4, forming a separation and communication transition between the sterilization chamber 3 and the filter chamber 4; a through groove 14 is provided on the partition 11, and the end of the through groove 14 away from the filter chamber 4 has a funnel-shaped structure, which can guide the hot water in the sterilization chamber 3 to flow smoothly into the through groove 14, avoid hot water splashing and residue, and at the same time increase the hot water inflow area and improve the filtration efficiency.

[0041] The partition 11 has slots on its side that communicate with the through groove 14. Two filter baskets 12 are slidably disposed in their respective slots, which can initially intercept larger impurities such as cooked meat scraps and grease mixed in with the hot water. The filter frame 13 is slidably disposed in the filter chamber 4 and located between the two partitions 11. The filter frame 13 has slots, the two ends of which are respectively connected to the corresponding through grooves 14. A filter element 15 is installed inside the slot. The hot water is deeply filtered by the filter element 15 to remove fine impurities. The filtered clean hot water can flow into the sterilization chamber 3 to be sterilized through the through groove 14 on the other side, realizing the circulation and purification of hot water.

[0042] According to one embodiment of the present invention, the filtration mechanism 7 further includes a sealing assembly for achieving a controllable seal between the filtration chamber 4 and the sterilization chamber 3; the inner wall of the filter frame 13 is provided with a sliding groove 16, and the top and bottom of the filter frame 13 are provided with openings 17 communicating with the sliding groove 16; two sets of sealing assemblies are provided and symmetrically arranged in the sliding groove 16, and the sealing assembly includes a sliding frame 18 and a sealing frame 19. The sliding frame 18 is slidably engaged with the sliding groove 16 and can move up and down along the sliding groove 16. One end of the sealing frame 19 is fixedly connected to the sliding frame 18, and the other end of the sealing frame 19 is slidably engaged with the opening 17. When hot water circulation filtration is required, the sliding frame 18 drives the sealing frame 19 to extend out of the opening 17 and abut against the port of the through groove 14 on the partition plate 11 to achieve a seal between the filtration chamber 4 and the sterilization chamber 3, preventing hot water leakage during the filtration process; when the filter mechanism 7 needs to be maintained and the filter element replaced, the sliding frame 18 drives the sealing frame 19 to retract into the opening 17, releasing the seal and facilitating operation by the operator.

[0043] The sealing components effectively solve the leakage problem during hot water circulation, avoid waste of water resources and heat energy, and prevent hot water leakage from damaging other parts of the equipment, thereby improving the stability and safety of equipment operation. The two sets of symmetrically arranged sealing components correspond to the connection points of the two sterilization chambers 3 and the filter chamber 4, respectively, and can achieve synchronous sealing to meet the needs of alternating operation of the two sterilization chambers 3.

[0044] According to one embodiment of the present invention, the filter mechanism 7 further includes an adjusting rod 20 and a cam 21; the outer side of the filter frame 13 is provided with a rotating hole communicating with the slide groove 16, the adjusting rod 20 is horizontally rotatably disposed in the rotating hole, the cam 21 is fixedly connected to the adjusting rod 20, and the cam 21 is located in the slide groove 16, and the outer peripheral surface of the cam 21 abuts against the sliding frame 18.

[0045] When the position of the sealing frame 19 needs to be adjusted, the adjusting rod 20 is rotated, causing the cam 21 to rotate synchronously. Utilizing the eccentric structure of the cam 21, the sliding frame 18 is pushed to slide along the groove 16. When the protruding end of the cam 21 abuts against the sliding frame 18, it pushes the sliding frame 18 towards the opening 17, causing the sealing frame 19 to extend and seal with the port of the through groove 14. When the recessed end of the cam 21 faces the sliding frame 18, the sliding frame 18 moves inward into the groove 16 under its own weight or a restoring force, causing the sealing frame 19 to retract into the opening 17, releasing the seal. It should be specifically noted that the cam 21 has two recessed and two protruding ends, arranged symmetrically, thus enabling synchronous sealing of the two sets of sealing components.

[0046] According to one embodiment of the present invention, the filter mechanism 7 further includes a handle 22 and a positioning screw 23; the handle 22 is fixedly connected to the adjusting rod 20, and the handle 22 is provided with a through hole that slides with the positioning screw 23; the outer side of the filter frame 13 is provided with a first screw hole 24 and a second screw hole 25 that are threadedly engaged with the positioning screw 23; when the positioning screw 23 is located in the first screw hole 24, the sealing frame 19 abuts against the port of the through groove 14; when the positioning screw 23 is located in the second screw hole 25, the sealing frame 19 is located in the opening 17.

[0047] When the handle 22 is turned to drive the adjusting rod 20, causing the sealing frame 19 to abut against the port of the through groove 14 (sealed state), the positioning screw 23 is moved so that it passes through the through hole of the handle 22 and is screwed into the first screw hole 24, thereby fixing the adjusting rod 20 and the cam 21 in place. This prevents the adjusting rod 20 from rotating accidentally during equipment operation or hot water flow, which could cause the sealing frame 19 to loosen or leak. When it is necessary to remove the seal for maintenance, the positioning screw 23 is unscrewed, the handle 22 is turned to drive the sealing frame 19 back, and the positioning screw 23 is screwed into the second screw hole 25 to fix the retracted state of the sealing frame 19, preventing the sealing frame 19 from accidentally extending and affecting the operation during maintenance.

[0048] According to one embodiment of the present invention, the sterilization mechanism 5 further includes an ultraviolet lamp 26, a temperature sensor, and a control terminal; a plurality of ultraviolet lamps 26 are provided and arranged in a ring array in the sterilization chamber 3. The main function of the ultraviolet lamps 26 is to continuously perform ultraviolet sterilization treatment on the circulating hot water in the sterilization chamber 3, kill harmful bacteria, microorganisms and other bacteria that grow in the hot water, avoid secondary pollution of the circulating hot water, and ensure that the hot water remains clean and sterile during reuse.

[0049] The heating component 8 is an electric heating rod, and both the electric heating rod and the temperature sensor are fixedly installed inside the sterilization chamber 3. The ultraviolet lamp 26, the temperature sensor, and the electric heating rod are all electrically connected to the control terminal. On the one hand, the control terminal can automatically adjust the start-up and shutdown of the electric heating rod and the heating power according to the preset sterilization temperature threshold to keep the water temperature stable within the range required for sterilizing cooked meat products. On the other hand, the control terminal can uniformly control the start-up and shutdown of the ultraviolet lamp 26 and its working time to achieve the coordinated operation of hot water ultraviolet sterilization and thermal sterilization, ensuring the automation and stability of the sterilization process.

[0050] According to one embodiment of the present invention, the sterilization mechanism 5 further includes a water-proof cover 27; a plurality of water-proof covers 27 are provided, and each covers the outside of a corresponding ultraviolet lamp 26. The water-proof cover 27 is made of a waterproof, high-temperature resistant, and light-transmitting material, which not only does not affect the penetration and irradiation of ultraviolet rays, but also completely isolates the ultraviolet lamp 26 from the hot water in the sterilization chamber 3, preventing hot water from directly contacting the lamp tube and wiring parts of the ultraviolet lamp 26, preventing the lamp tube from being damaged by short circuit due to water ingress, and at the same time preventing the ultraviolet lamp 26 from being corroded by hot water, thus extending the service life of the ultraviolet lamp 26.

[0051] According to one embodiment of the present invention, a drive rod 28 is rotatably disposed on the base 1; a drive gear 29 is fixedly disposed on the drive rod 28, and a driven gear 30 is fixedly disposed on the outer side of the sterilization tank 2, the driven gear 30 meshing with the drive gear 29; a drive motor is fixedly disposed on the base 1, and the output end of the drive motor is coaxially and fixedly connected to the drive rod 28.

[0052] When the sterilization tank 2 needs to be rotated, the drive motor is started. The output end of the drive motor drives the drive rod 28 to rotate, and the drive gear 29 rotates accordingly. Through gear meshing, the driven gear 30 and the sterilization tank 2 fixed thereto are driven to rotate smoothly around the base 1. This causes the two symmetrically distributed sterilization chambers 3 to alternately switch to the top (loading or unloading) and bottom (sterilization) positions of the sterilization tank 2, realizing the alternation of loading and sterilization.

[0053] According to one embodiment of the present invention, the material loading mechanism 6 further includes a slide rail 31, a base plate 32, and a limiting component; the slide rail 31 is horizontally fixedly connected to the sterilization tank 2, and the base plate 32 is slidably disposed on the slide rail 31; the limiting component is provided in several groups and arranged in a rectangular array on the base plate 32; the limiting component includes a first buckle 33, a second buckle 34, and a connecting plate 35; the first buckle 33 is fixedly connected to the base plate 32, the second buckle 34 is fixedly connected to the cover plate 10, and the two ends of the connecting plate 35 are respectively engaged and connected with the first buckle 33 and the second buckle 34.

[0054] After the material carrier 9 is placed and the cover plate 10 is closed, the two ends of the connecting plate 35 are respectively engaged with the corresponding first buckle 33 and second buckle 34 to fix the cover plate 10 to the base plate 32, thereby firmly limiting the stacked material carrier 9 on the base plate 32. When picking up or putting down the material carrier 9, the base plate 32 can be moved along the slide rail 31 to allow the material carrier 9 to enter and exit the sterilization chamber 3 as a whole, making the operation convenient.

[0055] The limiting component, through the cooperation of the connecting plate 35 with the first buckle 33 and the second buckle 34, can firmly fix the cover plate 10 and the base plate 32, thereby reliably limiting the stacked material frame 9 and preventing the material frame 9 from shaking, shifting or falling during the rotation of the sterilization tank 2. This not only ensures operational safety but also further improves operational efficiency.

[0056] A sterilization method for processing cooked meat products includes the following steps: Step 1: Place the cooked meat products to be sterilized one by one into each of the loading frames 9. After placement, cover the loading frame 9 furthest from the filter chamber 4 with the cover plate 10. The cover plate 10 is used to prevent the cooked meat products in the loading frames 9 from falling off during the subsequent rotation of the sterilization tank 2. Then, push the loading frames 9 containing the cooked meat products to be sterilized into the sterilization chamber 3 located at the top of the sterilization tank 2 along the axial direction of the sterilization tank 2. Step 2: Rotate the sterilization tank 2. At this time, the sterilization chamber 3 containing the cooked meat products to be sterilized gradually rotates towards the bottom of the sterilization tank 2. Meanwhile, the hot water in another sterilization chamber 3 will pass through the filter chamber 4 and the internal filter mechanism 7, and after filtration, it will flow into the rotating sterilization chamber 3. Step 3: When the sterilization chamber 3 containing the cooked meat products to be sterilized is completely rotated to the bottom of the sterilization tank 2, the heating component 8 in the sterilization mechanism 5 is activated to heat the hot water in the chamber and maintain the temperature within the constant range required for sterilization, ensuring that the cooked meat products are fully sterilized. Step 4: The operator pulls out the loading frame 9 located at the top of the sterilization tank 2 and inside the sterilization chamber 3, which has already undergone sterilization. Then, the sterilized cooked meat products are taken out and new cooked meat products to be sterilized are placed in.

[0057] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
