Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature sterilization devices, specifically, to a high-temperature sterilization device for meat processing. Background Technology

[0002] Meat products are foods made primarily from meat through various processing methods. These include cured meat products, cooked meat products, and fermented meat products. These meat products not only possess unique flavors and textures but also offer better preservation properties. To further ensure the food safety and quality of meat products, specialized high-temperature sterilization devices are typically used during processing. These devices effectively eliminate potential pathogenic microorganisms, maintaining stable and safe quality. However, in existing high-temperature sterilization devices, the hot water usually only contacts the top surface of the meat. During sterilization, the meat needs to be removed and rotated to ensure thorough disinfection, resulting in low sterilization efficiency.

[0003] To address the aforementioned issues, Chinese patent CN220211847U discloses a high-temperature sterilization device for meat products, comprising a sterilization mechanism, an exhaust pipe, a pressure relief mechanism, a bending plate, a sleeve plate, and a cylinder. It heats water in a storage tank using heating wires, generating high-temperature steam that completely envelops the meat products, achieving comprehensive sterilization. However, during the high-temperature sterilization process, because the heating wires are located at the bottom of the device, heat transfer relies primarily on natural convection. This results in a slow and uneven temperature rise within the device, significantly prolonging the sterilization time and potentially causing some products to fail to achieve the desired sterilization effect, thus impacting food safety and quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a high-temperature sterilization device for meat processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A high-temperature sterilization device for meat processing includes a sterilization chamber, a heating mechanism at the bottom of the sterilization chamber, a sterilization mechanism and a placement mechanism arranged sequentially above the heating mechanism, a sealing door that cooperates with the sterilization chamber on one side of the placement mechanism, and an exhaust pipe extending through the top of the sterilization chamber.

[0008] Furthermore, in order to ensure that the high-temperature sterilization device can effectively carry out sterilization operations, water is introduced into the bottom of the sterilization chamber through the water inlet pipe and heated by the heating wire, so that the water can be heated and evaporated, and then the water vapor can enter the top of the sterilization chamber to sterilize the meat products. The heating mechanism includes a heating wire set at the bottom of the sterilization chamber, a water inlet pipe that penetrates the sterilization chamber on one side of the heating wire, and a drain pipe that penetrates the sterilization chamber on the other side of the heating wire.

[0009] Furthermore, to improve the sterilization efficiency of the sterilization device, the expansion and contraction orifices accelerate and guide the water vapor, allowing it to enter the mixing tube. The flow of water vapor creates a negative pressure inside the hollow sphere, located between the expansion orifice and the mixing tube. This allows air from the sterilization chamber to enter the mixing tube through the air inlet pipe, mixing with the water vapor before exiting through the expansion pipe. This significantly shortens the time required for the sterilization device to reach the sterilization temperature and ensures temperature consistency within the sterilization chamber, thereby improving sterilization efficiency and quality. The sterilization mechanism includes... The device includes a partition plate positioned above the heating mechanism. Several connecting blocks are threaded through the top of the partition plate. Each connecting block has a contraction hole at its bottom, a buffer hole at its top, and an expansion hole at its top that mates with the connecting block. A hollow sphere is positioned on the outer top of each connecting block. An air inlet pipe mates with the expansion hole is threaded through one side of the hollow sphere. A mixing pipe mates with the expansion hole is threaded through the top of the hollow sphere. An expansion pipe is positioned at the top of the mixing pipe. A drain pipe mates with the partition plate is positioned at one end of each hollow sphere. The diameter of the top of the expansion hole is smaller than the diameter of the bottom of the mixing pipe.

[0010] Furthermore, to ensure that the meat products can come into full contact with water vapor to achieve the best sterilization effect, the meat products are placed inside the sterilization chamber with the support of several support blocks supporting the placement plate. With the further support of the support columns and support plates, a certain space is maintained between the bottom of the meat products and the placement plate, allowing the meat products to come into full contact with water vapor as much as possible, thereby ensuring the sterilization effect of the bottom of the meat products. The placement mechanism includes several support blocks symmetrically arranged on the inner wall of the sterilization chamber. The top of the two sets of support blocks located on the same horizontal line is equipped with a placement plate. The top of the placement plate has several ventilation holes. The top of the placement plate is equipped with several support columns, and the top of the support columns is equipped with support plates. The support columns are evenly arranged and distributed in a rectangular shape on the top of the placement plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the coordinated arrangement of a sterilization box, heating mechanism, sterilization mechanism, placement mechanism, sealing door, and exhaust pipe, can not only achieve sterilization of meat products and ensure the stable and safe quality of meat products, but also rapidly increase the temperature inside the sterilization device, enabling the sterilization device to quickly and evenly reach the sterilization temperature, greatly reducing the time required for sterilization and ensuring the sterilization effect of meat products.

[0013] 2. Through the sterilization mechanism, the water vapor is accelerated and guided by the shrinkage hole, buffer hole, and expansion hole, allowing water vapor to enter the mixing tube. Due to the flow of water vapor, a negative pressure is generated inside the hollow sphere and between the expansion hole and the mixing tube, allowing air in the sterilization chamber to enter the mixing tube from the air inlet pipe. The air and water vapor mix in the mixing tube and are discharged from the expansion pipe, which greatly shortens the time required for the sterilization device to reach the sterilization temperature and ensures the temperature consistency in the sterilization chamber, thereby improving sterilization efficiency and quality.

[0014] 3. Through the placement mechanism, the meat products can be placed inside the sterilization box under the support of several support blocks on the placement plate. With the further support of the support columns and support plates, a certain space is maintained between the bottom of the meat products and the placement plate, so that the meat products can come into full contact with water vapor as much as possible, thereby ensuring the sterilization effect of the bottom of the meat products.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a high-temperature sterilization device for meat processing is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the high-temperature sterilization device for meat processing according to an embodiment of the present invention includes a sterilization box 1, a heating mechanism 2 is provided at the bottom of the sterilization box 1, a sterilization mechanism 3 and a placement mechanism 4 are arranged sequentially above the heating mechanism 2, a sealing door 5 that cooperates with the sterilization box 1 is provided on one side of the placement mechanism 4, and an exhaust pipe 6 is provided through the top of the sterilization box 1.

[0027] By utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of sterilization box 1, heating mechanism 2, sterilization mechanism 3, placement mechanism 4, sealing door 5 and exhaust pipe 6, this utility model can not only achieve sterilization treatment of meat products and ensure the stable and safe quality of meat products, but also rapidly increase the temperature inside the sterilization device, enabling the sterilization device to quickly and evenly reach the sterilization temperature, greatly reducing the time required for sterilization and ensuring the sterilization effect of meat products.

[0028] In one embodiment, the heating mechanism 2 includes a heating wire 201 disposed at the bottom of the sterilization chamber 1. A water inlet pipe 202 penetrating the sterilization chamber 1 is disposed on one side of the heating wire 201, and a drain pipe 203 penetrating the sterilization chamber 1 is disposed on the other side of the heating wire 201. Water is introduced into the bottom of the sterilization chamber 1 through the water inlet pipe 202, and the water is heated by the heating wire 201, so that the water can be heated and evaporated, and then the water vapor can enter the top of the sterilization chamber 1 to sterilize the meat products.

[0029] In one embodiment, the sterilization mechanism 3 includes a partition 301 disposed above the heating mechanism 2. A plurality of connecting blocks 302 are disposed through the top of the partition 301. A contraction hole 303 is formed at the bottom of each connecting block 302. A buffer hole 304 is formed at the top of each contraction hole 303. An expansion hole 305, cooperating with the connecting block 302, is formed at the top of each buffer hole 304. A hollow sphere 306 is disposed on the outer side of the top of the connecting block 302. An air inlet pipe 307, cooperating with the expansion hole 305, is disposed through one side of the hollow sphere 306. A mixing pipe 308, cooperating with the expansion hole 305, is disposed through the top of the hollow sphere 306. An expansion pipe 309 is formed at the top of the mixing pipe 308. One end of each hollow sphere 306... A drain pipe 310 is provided to cooperate with the partition 301; the diameter of the top of the expansion hole 305 is smaller than the diameter of the bottom of the mixing pipe 308; under the accelerating and guiding effect of the contraction hole 303, buffer hole 304 and expansion hole 305 on water vapor, water vapor can enter the mixing pipe 308. Due to the flow of water vapor, a negative pressure is generated inside the hollow ball 306 and between the expansion hole 305 and the mixing pipe 308, so that the air in the sterilization chamber 1 can enter the mixing pipe 308 from the air inlet pipe 307, so that the air and water vapor are mixed in the mixing pipe 308 and discharged from the expansion pipe 309. This greatly shortens the time required for the sterilization device to reach the sterilization temperature and ensures the temperature consistency in the sterilization chamber 1, thereby improving the sterilization efficiency and quality.

[0030] In one embodiment, the placement mechanism 4 includes several support blocks 401 symmetrically arranged on the inner wall of the sterilization chamber 1. Two sets of support blocks 401 located on the same horizontal line have placement plates 402 at their top ends. The top ends of the placement plates 402 have several ventilation holes 403, and the top ends of the placement plates 402 have several support columns 404. The top ends of the support columns 404 have support plates 405. The support columns 404 are evenly arranged and rectangularly distributed at the top ends of the placement plates 402. With the support of the support blocks 401 on the placement plates 402, meat products can be placed inside the sterilization chamber 1. Furthermore, with the support columns 404 and support plates 405 providing additional support, a certain space is maintained between the bottom of the meat products and the placement plates 402, allowing the meat products to fully contact the water vapor, thereby ensuring the sterilization effect at the bottom of the meat products.

[0031] In addition, it should be noted that in order to prevent excessive steam pressure inside the sterilization device, a pressure relief valve is installed inside the exhaust pipe 6. This pressure relief valve is existing technology and will not be elaborated on further here.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In practical application, by opening the sealing door 5, workers can place meat products on the placement plate 402. Supported by the support plate 405, the bottom of the meat products is kept at a certain distance from the placement plate 402, allowing the bottom of the meat products to contact the water vapor for subsequent sterilization. If there is insufficient space above the placement plate 402 for placing the meat products, the placement plate 402 can be supported by two sets of support blocks 401 at the same horizontal level below. The sealing door 5 is then closed. Water is introduced into the sterilization chamber 1 through the water inlet pipe 202 and heated by the heating wire 201, causing the water to evaporate. The water vapor then passes through the contraction hole 303, buffer hole 304, and expansion hole 305. As the diameter of the contraction hole 303 gradually decreases, the flow rate of the water vapor increases. 3. The buffer hole 304 and expansion hole 305 accelerate and guide the water vapor, allowing it to enter the mixing tube 308. The flow of water vapor creates a negative pressure inside the hollow ball 306 and between the expansion hole 305 and the mixing tube 308, allowing air in the sterilization chamber 1 to enter the mixing tube 308 through the air inlet pipe 307. This mixes the air with the water vapor in the mixing tube 308 and discharges it through the expansion pipe 309, greatly shortening the time required for the sterilization device to reach the sterilization temperature and ensuring the temperature consistency within the sterilization chamber 1. This allows the water vapor to sterilize the meat products on top of the sterilization chamber 1. During the sterilization process, the exhaust pipe 6 ensures a constant air pressure in the sterilization chamber 1. After sterilization, the sealing door 5 is opened to remove the meat products, and the water in the device is discharged through the drain pipe 203 and the drain pipe 310.

[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the sterilization chamber 1, heating mechanism 2, sterilization mechanism 3, placement mechanism 4, sealing door 5, and exhaust pipe 6, not only can meat products be sterilized, ensuring the stable and safe quality of meat products, but the temperature inside the sterilization device can also be rapidly increased, enabling the sterilization device to quickly and evenly reach the sterilization temperature, greatly reducing the sterilization time and ensuring the sterilization effect of meat products. Through the sterilization mechanism 3, under the accelerating and guiding effect of the shrinkage hole 303, buffer hole 304, and expansion hole 305 on water vapor, water vapor can enter the mixing tube 308. Due to the flow of water vapor, a vapor is generated inside the hollow sphere 306 located between the expansion hole 305 and the mixing tube 308. The negative pressure allows air inside the sterilization chamber 1 to enter the mixing pipe 308 through the air inlet pipe 307, where air and water vapor mix and are discharged through the expansion pipe 309. This significantly shortens the time required for the sterilization device to reach the sterilization temperature and ensures the temperature consistency within the sterilization chamber 1, thereby improving sterilization efficiency and quality. The placement mechanism 4, supported by several support blocks 401 on the placement plate 402, allows meat products to be placed inside the sterilization chamber 1. Further support from the support columns 404 and support plates 405 ensures that the bottom of the meat product has sufficient space with the placement plate 402, allowing the meat product to fully contact the water vapor and thus ensuring the sterilization effect at the bottom of the meat product.
