Description

Technical Field

[0001] This invention relates to the field of constant temperature heating cylinder technology, specifically to a circulating constant temperature heating cylinder for efficient cooking of cooked meat products. Background Technology

[0002] In the cooked meat processing industry, cooking is the core process that determines the taste, flavor, and quality of the product. The circulating constant-temperature heating tank, as a key piece of equipment in large-scale production, functions primarily to maintain a stable temperature of the cooking liquid (broth, stock, etc.) within the tank, ensuring uniform cooking and flavor absorption of the cooked meat products. Simultaneously, it improves cooking efficiency through liquid circulation, meeting the demands of continuous industrial production. As cooked meat processing shifts towards large-scale, standardized, and high-quality production, the cleanliness and circulation stability of the cooking liquid have an increasingly significant impact on product quality. The circulating filtration system, as a core component ensuring the cleanliness of the cooking liquid, directly determines the cooking effect and product qualification rate of the heating tank.

[0003] During the cooking process of cooked meat products, various impurities inevitably arise in the cooking liquid within the tank. These mainly include scum formed from blood, myoglobin, and hemoglobin released during the heating process, as well as solid impurities such as meat scraps, tendons, spice residues, and collagen coagulation. If these impurities remain in the cooking liquid for a long time, they will cause a series of problems: Firstly, impurities will suspend in the liquid or settle at the bottom of the tank, causing the cooking liquid to become turbid. This not only causes impurities to adhere to the surface of the meat products, affecting the consistency and cleanliness of the product's appearance, but also introduces a fishy or gamey odor, damaging the flavor purity of the meat products and reducing product quality. Secondly, the long-term accumulation of impurities will clog the circulation pipes, heating elements, and temperature sensors of the hot tank, leading to poor liquid circulation and decreased accuracy in constant temperature control. This not only reduces cooking efficiency but also accelerates equipment wear and tear, increases equipment maintenance costs, and may even cause uneven cooking, undercooked meat, or burnt meat due to localized overheating, further affecting the product qualification rate.

[0004] In existing technologies, to address the aforementioned problems, conventional circulating thermostatic heating cylinders are typically equipped with simple filtration structures, commonly including a single filter screen in the circulation pipeline. However, this filtration method is insufficient to meet the demands for cleanliness and circulation stability of the cooking liquid in large-scale production. Firstly, the filtration precision of a single filter screen is low, only able to filter larger particles of meat scraps and spice residues, failing to effectively filter fine impurities such as foam and collagen coagulation. The filtration effect is poor, and impurities will re-enter the cylinder with the circulating liquid, making it difficult to fundamentally solve the liquid turbidity problem. Secondly, the filter screen is easily clogged by impurities during use, requiring frequent manual disassembly and cleaning. This not only increases the labor intensity of operators but also interrupts the cooking process, affecting production continuity and reducing production efficiency. Summary of the Invention

[0005] To overcome the above-mentioned defects, the present invention provides a circulating constant temperature heating cylinder for efficient cooking of cooked meat products, which solves the technical problem that the filtration effect is easily affected by impurities during the liquid circulation filtration process in the existing heating cylinder.

[0013] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, by setting up a liquid circulation mechanism, the operation of the diaphragm pump can drive the liquid to circulate between the filter box and the cylinder. During the liquid circulation process, the liquid can be filtered through the filter cylinder, thereby accumulating the impurities generated during the cooking process in the filter box, thus preventing the impurities from flowing back into the cylinder and affecting the cooking effect of the cooked meat. 2. In this invention, the cleaning mechanism enables the first motor to rotate the support plate, which in turn drives the first and third gears to move in a circular motion. The first and third gears mesh with the first gear ring, respectively, to rotate the threaded rod and splined rod. The rotation of the threaded rod causes the moving ring and cleaning ring to move on the surface of the filter cartridge, while the rotation of the splined rod causes the cleaning ring to rotate. This facilitates the cleaning of impurities on the filter cartridge surface using the cleaning brushes on the cleaning ring. Simultaneously, the discharge pipe allows for the discharge of impurities and small amounts of liquid from the filter box, thus facilitating the cleaning and impurity removal of the filter cartridge.

At the same time, the rotation of the threaded rod 16 can drive the moving ring 14 and the cleaning ring 15 on the moving ring 14 to move, thereby facilitating the cleaning of the filter cartridge 6 by the cleaning bristles.

[0025] Reference Figures 4-7 The second rotating mechanism includes an annular groove, a first driving groove, and a third rotating mechanism.

Specifically, the operation of the first motor 20 can drive the support plate 5 to rotate, and the rotation of the support plate 5 can drive the first gear 18 to move around the support plate 5. At the same time, the meshing of the first gear 18 with the first gear ring 17 can drive the first gear 18 and the threaded rod 16 to rotate.

[0026] Reference Figures 5-9The first rotating mechanism includes a first cavity, a second gear ring 22, and a rotating assembly. The first cavity is located inside the moving ring 14 and communicates with the cleaning tank. A second gear 21 is rotatably mounted inside the first cavity.

Then, through the meshing of the third gear 26 with the first toothed ring 17, the third gear 26 and the spline rod 25 are driven to rotate. Thus, through the cooperation of the spline rod 25 and the spline opening 24, the second gear 21 is driven to rotate. At the same time, through the meshing of the second gear 21 with the second toothed ring 22, the cleaning ring 15 is driven to rotate. This facilitates the cleaning effect of the filter cartridge 6 by the cleaning bristles. At the same time, it works with the discharge pipe to discharge impurities and a small amount of liquid in the filter box 3, thus facilitating the cleaning and impurity removal of the filter cartridge 6.

[0027] In this embodiment, during use, the operator adds cooked meat and cooking liquid to the tank 1 for heating and cooking. At the same time, the operator controls the diaphragm pump 9 to work. The operation of the diaphragm pump 9 can drive the liquid to flow between the filter box 3 and the tank 1. During the liquid flow, the liquid can be filtered through the filter cylinder 6, thereby accumulating the impurities generated during the cooking process in the filter box 3, thus preventing the impurities from flowing back into the tank 1 and affecting the cooking effect of the cooked meat. After cooking is completed, the operator opens the impurity discharge control valve to discharge a certain amount of cooking liquid. During the drainage process, the operator controls the first motor 20 to work. The operation of the first motor 20 can drive the support plate 5 to rotate. At the same time, the rotation of the support plate 5 can drive the first gear 18 and the third gear 26 to move in a circle with the rotation of the support plate 5. Then, through the meshing of the first gear 18 and the third gear 26 with the first gear ring 17, the threaded rod 16 and the spline rod 25 are driven to rotate. Through the rotation of the threaded rod 16, the moving ring 14 and the cleaning ring 15 can be driven to move on the surface of the filter cylinder 6, so that the outer wall of the filter cylinder 6 can be cleaned by the cleaning brush. During the rotation of the spline rod 25, the second gear 21 can be driven to rotate through the cooperation between the spline rod 25 and the spline opening 24. At the same time, the second gear 21 and the second gear ring 22 can drive the cleaning ring 15 to rotate, thereby facilitating the cleaning effect of the cleaning brush on the filter cartridge 6. Simultaneously, the impurities and a small amount of liquid in the filter box 3 can be discharged through the discharge pipe, thus facilitating the cleaning and impurity removal of the filter cartridge 6. Afterwards, the operator closes the discharge control valve and adds the boiling liquid into the cylinder 1, thereby achieving the impurity removal treatment of the boiling liquid.
