Description

Technical Field

[0001] This utility model relates to the field of aquatic product processing technology, specifically a vacuum tumbling machine for aquatic product processing. Background Technology

[0002] Currently, the pickling and processing of aquatic products mainly involves soaking in seasoning solutions, using water-retaining additives, and manually stirring to coat the product with a batter or starch. As the soaking time increases, the aquatic products gradually absorb flavor from the outside in. However, these pickling methods are difficult to effectively control in terms of processing temperature, humidity, production time, and harmful microorganisms and pathogens in the processing environment, resulting in low mass production feasibility and a significant proportion of labor costs in production. Furthermore, under normal atmospheric pressure, the tissue structure of aquatic products cannot be improved, making it difficult to enhance product quality and yield. In addition, after soaking, aquatic products experience significant weight loss (due to moisture loss during cooking) and changes in tissue density (15%-30%) during heat treatment, leading to a decline in taste and loss of the pickled flavor.

[0003] Tumbling is a physical process of energy conversion in meat. It promotes the distribution of the liquid medium (salt water), improves the tenderness of the meat, and enhances the extraction and movement of salt-soluble proteins to the surface of the meat. Tumbling machines utilize the principle of physical impact, causing the meat to tumble inside the drum, resulting in collisions and beatings between the meat and the impellers inside the drum, and among the meat pieces themselves, achieving a massaging and marinating effect.

[0004] Currently, the tumbling and kneading processing of aquatic products generally relies on unidirectional rotary equipment, whose core bottleneck lies in the single dimension of motion. Traditional tumbling drums can only rotate around an axis, causing raw materials to accumulate at the bottom of the drum due to centrifugal force. The blade coverage is too low, requiring frequent shutdowns for manual turning, thus extending the processing cycle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vacuum tumbling machine for processing aquatic products. It solves the problems of traditional tumbling drums that can only rotate around an axis, causing raw materials to accumulate at the bottom of the drum due to centrifugal force, resulting in low blade coverage and requiring frequent machine stops for manual turning, thus extending the processing cycle.

[0006] This utility model provides the following technical solution: a vacuum tumbling machine for processing aquatic products, comprising a support plate and a vacuum tumbling cylinder, wherein the vacuum tumbling cylinder is provided with multiple blades, four telescopic rods are fixedly installed on the upper surface of the support plate, an mounting plate is fixedly installed between the top ends of the telescopic rods, two limiting plates are fixedly installed on the upper surface of the mounting plate, the vacuum tumbling cylinder passes through the limiting plates, the vacuum tumbling cylinder is rotatably connected to the limiting plates, a first bevel gear is fixedly installed on the outer surface of the vacuum tumbling cylinder, and an outer cylinder is rotatably installed on the upper surface of the mounting plate, the top end of the outer cylinder... A second bevel gear is fixedly installed, and the second bevel gear meshes with the first bevel gear. A drive motor is fixedly installed on the upper surface of the support plate. A crankshaft is fixedly installed at the output end of the drive motor. A bushing is fitted on the outer surface of the crankshaft. A connecting rod connects the bushing and the mounting plate. The connecting rod is hinged to the mounting plate. A third bevel gear is fixedly installed at the end of the crankshaft away from the drive motor. An inner cylindrical rod is inserted inside the outer cylinder. A fourth bevel gear is fixedly installed on the outer surface of the inner cylindrical rod. The fourth bevel gear meshes with the third bevel gear.

[0007] Preferably, the telescopic rod includes a mounting column and a support column, one end of the support column penetrates and extends into the interior of the mounting column, and a spring is fixedly installed between the support column and the inner wall of the mounting column.

[0008] Preferably, two retaining rings are fixedly installed on the outer surface of the vacuum tumbling drum.

[0009] Preferably, the limiting plate includes two plates, and a plate connecting member is fixedly connected between the two plates. One side of each of the two plates is an arc-shaped surface, and a limiting groove is formed on the outer surface of the arc-shaped surface. The limiting groove is adapted to the fixing ring.

This allows fragile raw materials such as fish and shrimp to receive uniform and gentle tumbling treatment, significantly improving the product's texture integrity and flavor integration.

Detailed Implementation

[0015] Please see Figure 1-5A vacuum tumbling machine for processing aquatic products includes a support plate 1 and a vacuum tumbling drum 2. The vacuum tumbling drum 2 contains multiple blades and has a feed nozzle at one end. Four telescopic rods 3 are fixedly mounted on the upper surface of the support plate 1, and an mounting plate 4 is fixedly mounted between the top ends of the telescopic rods 3. Two limiting plates 5 are fixedly mounted on the upper surface of the mounting plate 4. The vacuum tumbling drum 2 passes through the limiting plates 5 and is rotatably connected to the limiting plates 5. A first bevel gear 6 is fixedly mounted on the outer surface of the vacuum tumbling drum 2. An outer cylinder 7 is rotatably mounted on the upper surface of the mounting plate 4, and a second bevel gear 6 is fixedly mounted at the top end of the outer cylinder 7. A bevel gear 8 is fitted with a second bevel gear 8 and a first bevel gear 6. A drive motor 9 is fixedly mounted on the upper surface of the support plate 1. A crankshaft 10 is fixedly mounted on the output end of the drive motor 9. A bushing 11 is fitted on the outer surface of the crankshaft 10. A connecting rod 12 is connected between the bushing 11 and the mounting plate 4. The connecting rod 12 is hinged to the mounting plate 4. A third bevel gear 13 is fixedly mounted on the end of the crankshaft 10 away from the drive motor 9. An inner cylindrical rod 14 is inserted inside the outer cylindrical column 7. A fourth bevel gear 15 is fixedly mounted on the outer surface of the inner cylindrical rod 14. The fourth bevel gear 15 meshes with the third bevel gear 13.

[0016] The outer cylinder 7 has a cavity inside, and two elongated limiting grooves 701 are opened on the inner wall of the cavity. Two elongated fixing protrusions 702 are fixedly installed on the outer surface of the inner cylinder 14, and the elongated limiting grooves 701 and the elongated fixing protrusions 702 fit together.

[0017] When the outer cylinder 7 rotates, the outer cylinder 7 drives the inner cylinder 14 to rotate synchronously through the elongated limiting groove 701 and the elongated fixing protrusion 702; When the outer cylinder 7 moves up and down, the outer cylinder 7 drives the elongated limiting groove 701 to move up and down along the elongated fixed protrusion 702, ensuring that when the outer cylinder 7 drives the inner cylinder 14 to rotate, the outer cylinder 7 can also move up and down at the same time, ensuring that the rotational motion and the lifting motion of the outer cylinder 7 do not interfere with each other.

[0018] In use, after the aquatic products are added into the vacuum tumbling drum 2, the drive motor 9 drives the crankshaft 10 to rotate. The crankshaft 10 drives the third bevel gear 13 to rotate through the fourth bevel gear 15, thereby driving the inner rod 14 to rotate. The inner rod 14 drives the outer cylinder 7 to rotate through the elongated limiting groove 701 and the elongated fixing protrusion 702. The outer cylinder 7 drives the vacuum tumbling drum 2 to rotate through the meshing second bevel gear 8 and the first bevel gear 6, thereby achieving the effect of tumbling the aquatic products in the vacuum tumbling drum 2.

[0019] While the drive motor 9 drives the crankshaft 10 to rotate, the crankshaft 10 drives the mounting plate 4 to move up and down reciprocally through the bushing 11 and the connecting rod 12. The mounting plate 4 drives the vacuum tumbling drum 2 to move up and down reciprocally, so that the aquatic products in the vacuum tumbling drum 2 can fully contact the paddles, which improves the working quality of the aquatic product tumbling processing, shortens the working time, and improves the working efficiency.

[0020] The telescopic rod 3 includes a mounting post 301 and a support post 302. One end of the support post 302 passes through and extends into the interior of the mounting post 301, and a spring 303 is fixedly installed between the support post 302 and the inner wall of the mounting post 301 to achieve the telescopic effect and provide stable support for the mounting plate 4.

[0021] Two retaining rings 16 are fixedly installed on the outer surface of the vacuum tumbling drum 2.

[0022] The limiting plate 5 includes two plates 501, and a plate connector 502 is fixedly connected between the two plates 501. The opposite side of the two plates 501 is set as an arc surface, and a limiting groove 503 is opened on the outer surface of the arc surface. The limiting groove 503 is adapted to the fixing ring 16.

[0023] The vacuum tumbling drum 2 is guaranteed to rotate stably within the limiting plate 5. The limiting slide 503 and the fixing ring 16 ensure that the vacuum tumbling drum 2 will not be displaced in the horizontal direction. The two symmetrically designed plates 501 ensure that the vacuum tumbling drum 2 will not be displaced in the vertical direction. There is a gap between the connecting plate and the fixing ring 16 to facilitate the user to add lubricating oil and facilitate later maintenance. Four evenly distributed casters 17 are fixedly installed on the lower surface of the support plate 1, which facilitates operation and movement.

[0024] In summary, this vacuum tumbling machine for aquatic product processing achieves 360° rotation and vertical lifting of the tumbling drum through the coordinated operation of a bevel gear set, crankshaft, outer cylinder, and inner rod. This allows the raw materials to collide and penetrate the blades at multiple angles in a vacuum environment, significantly shortening the flavor infusion period. Furthermore, the precise control of the complex motion trajectory is ensured through the fitting of long grooves and protrusions, overcoming the limitations of traditional unidirectional movement. This allows fragile raw materials such as fish and shrimp to receive uniform and gentle tumbling treatment, significantly improving the product's textural integrity and flavor integration.
