Description

Technical Field

[0001] This utility model relates to the field of food preservation technology, and in particular to a preservation device that integrates an adjustable ice slurry nozzle and an anti-ice crystal guide plate. Background Technology

[0002] In the field of aquatic product preservation, ice slurry preservation technology, with its efficient and rapid cooling capabilities, can effectively inhibit the growth of microorganisms and enzyme activity, thereby extending the shelf life of aquatic products. It is widely used in the preservation of large yellow croaker.

[0003] The existing preservation equipment integrating an adjustable ice slurry nozzle and an anti-ice crystal guide plate has the following shortcomings:

[0004] On the one hand, the flow rate and particle size of ice slurry from traditional ice slurry nozzles are uncontrollable, and the spray angle is fixed, making it difficult to meet the preservation needs of large yellow croaker of different sizes and at different processing stages. This results in uneven ice slurry coverage and a significant reduction in preservation effect. On the other hand, during the quick-freezing process, the direction of cold air flow inside the equipment is unreasonable, and sharp ice crystals are easily formed on the surface of the fish skin. These ice crystals can pierce the fish skin and damage the fish's tissue structure, which not only affects the appearance quality of the large yellow croaker but also accelerates the oxidation and spoilage of the fish meat, reducing the economic value of the product. Utility Model Content

[0005] This invention proposes a preservation device that integrates an adjustable ice slurry nozzle and an anti-ice crystal guide plate. By optimizing the ice slurry spraying method and the direction of cold air flow in the quick-freezing module, it effectively improves the ice slurry preservation effect of large yellow croaker and reduces damage to the fish, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a preservation device integrating an adjustable ice slurry nozzle and an anti-ice crystal guide plate, comprising a quick-freezing box, wherein a pretreatment component is fixedly connected to the top right side of the quick-freezing box, and a refrigeration unit is fixedly connected to the top left side of the quick-freezing box.

[0007] The pretreatment component includes a connecting frame, with a conveying pipe fixedly connected to the top of the connecting frame, and a fan-shaped nozzle fixedly connected to the bottom end of the conveying pipe extending through the upper surface of the inner wall of the connecting frame.

[0008] The fan-shaped nozzle includes a nozzle body, which is fixedly connected to the bottom end of the delivery pipe. A spiral guide vane is fixedly connected inside the nozzle body. Rotating baffles are rotatably connected to the left and right sides of the bottom of the inner surface of the nozzle body. A push rod is movably connected to the top of the rotating baffle. A connecting ring is movably connected to the top of the two push rods. An adjusting ring is rotatably connected to the outer surface of the connecting ring. The inner surface of the adjusting ring is threadedly connected to the outer surface of the nozzle body.

[0009] Preferably, a conveyor belt is provided on the top right side of the quick-freezing box, the conveyor belt is located at the bottom of the pretreatment component, and an inclined chute is provided on the left side of the conveyor belt.

[0010] Preferably, the inclined slide is located at the top of the quick-freezing box and extends to the right side of the inner wall of the quick-freezing box at its bottom end, and a door is rotatably connected to the left end of the quick-freezing box.

[0011] Preferably, the connecting frame is fixedly connected to the top right side of the quick-freezing box, a sliding baffle is slidably connected to the right end of the connecting frame, and a control valve is fixedly connected to the middle of the outer surface of the conveying pipe.

[0012] Preferably, a connecting pipe is fixedly connected to the bottom center of the refrigeration unit, and the bottom end of the connecting pipe extends into the interior of the quick-freezing box.

[0013] Preferably, the bottom end of the connecting pipe is fixedly connected to an anti-ice crystal damage guide frame, the anti-ice crystal damage guide frame is located inside the upper part of the quick-freezing box, and a number of wave-shaped bionic fins are fixedly connected to the inner surface of the anti-ice crystal damage guide frame.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, the fan-shaped nozzle utilizes the cooperation of the nozzle body, spiral guide vane, rotating baffle, push rod, connecting ring, and adjusting ring. The spiral guide vane, fixed inside the nozzle body, provides initial guidance to the ice slurry entering the nozzle, giving it a certain dispersion tendency. The adjusting ring is threadedly connected to the nozzle body. When the adjusting ring is rotated, the connecting ring moves up and down through the threaded transmission. The connecting ring then pushes the rotating baffle to rotate through the push rod, thereby changing the shape and size of the ice slurry spray channel. Based on this principle, this structure achieves controllable ice slurry flow rate and particle size, as well as flexible adjustment of the spray angle between 30° and 120°. In practical applications, for large yellow croaker of different sizes, operators can adjust the adjusting ring as needed to ensure that the ice slurry evenly covers the surface of the fish, avoiding the problem of poor local preservation effect caused by uneven ice slurry coverage. This significantly improves the preservation effect and meets the preservation needs of large yellow croaker at different processing stages.

[0016] 2. In this utility model, through the cooperation between the refrigeration unit, the connecting pipe, and the anti-ice crystal damage guide frame and its inner wave-shaped bionic fins, the refrigeration unit generates cold airflow, which is transported to the inside of the quick-freezing box through the connecting pipe. The anti-ice crystal damage guide frame is set at the bottom of the connecting pipe, and the wave-shaped bionic fins on its surface are arranged in a specific direction. When the cold airflow passes through the guide frame, the wave-shaped bionic fins will comb and guide the cold airflow. The principle is to use the special shape of the fins to disperse the concentrated cold airflow into a uniform and gentle airflow. This allows the cold airflow to act on the surface of the large yellow croaker with a more reasonable flow direction and speed, reducing the formation of sharp ice crystals on the fish skin surface. Because the uniform cold airflow can avoid local overcooling of the fish body, prevent excessive growth of ice crystals and puncture of the fish skin, thereby effectively maintaining the integrity of the fish body, ensuring the freshness of the large yellow croaker, and improving the economic value of the product.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a quick-freezing box 1, a pretreatment component 2 fixedly connected to the top right side of the quick-freezing box 1, and a refrigeration unit 3 fixedly connected to the top left side of the quick-freezing box 1. The pretreatment component 2 includes a connecting frame 21, a conveying pipe 23 fixedly connected to the top of the connecting frame 21, the bottom end of the conveying pipe 23 penetrating to the upper surface of the inner wall of the connecting frame 21 and fixedly connected to a fan-shaped nozzle 25, the fan-shaped nozzle 25 including a nozzle body 251, the nozzle body 251 fixedly connected to the bottom end of the conveying pipe 23, a spiral guide vane 252 fixedly connected inside the nozzle body 251, and rotating baffles 253 rotatably connected to the left and right sides of the bottom of the inner surface of the nozzle body 251. A pusher is movably connected to the top of the rotating baffle 253. A connecting ring 255 is movably connected to the top of the two push rods 254. An adjusting ring 256 is rotatably connected to the outer surface of the connecting ring 255. The inner surface of the adjusting ring 256 is threadedly connected to the outer surface of the nozzle body 251. A conveyor belt 11 is provided on the top right side of the quick-freezing box 1. The conveyor belt 11 is located at the bottom of the pretreatment component 2. An inclined chute 12 is provided on the left side of the conveyor belt 11. The inclined chute 12 is opened at the top of the quick-freezing box 1 and its bottom end extends to the right side of the inner wall of the quick-freezing box 1. A box door 13 is rotatably connected to the left end of the quick-freezing box 1. A connecting frame 21 is fixedly connected to the top right side of the quick-freezing box 1. A sliding baffle 22 is slidably connected to the right end of the connecting frame 21. A control valve 24 is fixedly connected to the middle of the outer surface of the conveying pipe 23.

[0025] The overall effect of Embodiment 1 is as follows: When the large yellow croaker is placed on the conveyor belt 11, the conveyor belt 11 transports the large yellow croaker to the pretreatment component 2. The flow rate of the ice slurry is controlled by adjusting the control valve 24. The ice slurry enters the fan-shaped nozzle 25 through the conveying pipe 23. According to the size of the large yellow croaker and the preservation requirements, the operator rotates the adjusting ring 256. The adjusting ring 256 drives the connecting ring 255 to move up and down through the threaded transmission. The connecting ring 255 then pushes the rotating baffle 253 to rotate through the push rod 254, changing the shape and size of the ice slurry spray channel. At the same time, the spiral guide plate 252 disperses the ice slurry, so that the ice slurry evenly covers the surface of the large yellow croaker with a suitable flow rate, particle size and spray angle within the range of 30°-120°, completing the pretreatment and effectively improving the targeting and effectiveness of the large yellow croaker preservation treatment.

[0026] Example 2: Figure 2 and Figure 4As shown, this utility model provides a technical solution: a connecting pipe 31 is fixedly connected to the bottom center of the refrigeration unit 3, the bottom end of the connecting pipe 31 extends into the interior of the quick-freezing box 1, an anti-ice crystal damage guide frame 32 is fixedly connected to the bottom end of the connecting pipe 31, the anti-ice crystal damage guide frame 32 is set above the interior of the quick-freezing box 1, and a number of wave-shaped bionic fins 321 are fixedly connected to the inner surface of the anti-ice crystal damage guide frame 32.

[0027] The effect achieved by the entire embodiment 2 is as follows: After the refrigeration unit 3 is started, the generated cold airflow is transported to the quick-freezing box 1 through the connecting pipe 31. During the downward flow of the cold airflow, it first passes through the anti-ice crystal damage guide frame 32. The wave-shaped bionic fins 321 on the anti-ice crystal damage guide frame 32 are arranged in a specific direction and pattern. They use their special shape to comb and guide the cold airflow, dispersing the concentrated cold airflow into a uniform and gentle airflow. The uniform and gentle cold airflow acts on the surface of the large yellow croaker, avoiding local overcooling of the fish body, effectively reducing the formation of sharp ice crystals on the surface of the fish skin, maintaining the integrity of the fish body, and ensuring the freshness of the large yellow croaker during the quick-freezing process.

[0028] The working principle of the entire equipment is as follows: First, the large yellow croaker to be preserved is placed on the conveyor belt 11 on the top right side of the quick-freezing box 1. The conveyor belt 11 is started, which moves the large yellow croaker to the left and into the pretreatment component 2. At this time, the external ice slurry supply system delivers ice slurry to the fan-shaped nozzle 25 through the conveying pipe 23. According to the size and quantity of the large yellow croaker and the preservation requirements, the operator rotates the adjusting ring 256 to adjust the spray angle of the fan-shaped nozzle 25 and controls the ice slurry flow rate through the control valve 24. The spiral guide plate 252 initially disperses the ice slurry entering the nozzle. The rotating baffle 253 changes the ice slurry spray channel under the linkage of the adjusting ring 256, the connecting ring 255 and the push rod 254, so that the ice slurry is sprayed evenly on the surface of the large yellow croaker with appropriate flow rate, particle size and angle, thus completing the ice slurry pretreatment.

[0029] After pretreatment, the large yellow croaker continues to move to the left along the conveyor belt 11 and reaches the inclined chute 12. Under the action of gravity, the large yellow croaker slides into the quick-freezing box 1 along the inclined chute 12. At the same time, the refrigeration unit 3 starts, and the generated low-temperature cold airflow is transported into the quick-freezing box 1 through the connecting pipe 31. After entering the quick-freezing box 1, the cold airflow passes through the anti-ice crystal damage guide frame 32. The wave-shaped bionic fins 321 sort and guide the cold airflow, transforming the originally concentrated and disordered cold airflow into a uniform and gentle airflow, so that it evenly covers the surface of the large yellow croaker. The uniform cold airflow can cool all parts of the large yellow croaker at the same time, avoid uneven ice crystal growth caused by local temperature differences, reduce ice crystal puncture damage on the fish skin surface, and achieve efficient quick-freezing and preservation of the large yellow croaker.

[0030] After the large yellow croaker has completed the quick-freezing and preservation process, the operator can open the door 13 on the left side of the quick-freezing box 1 and take the large yellow croaker out of the quick-freezing box 1 for subsequent packaging, storage or transportation operations. During the operation of the equipment, the sliding baffle 22 on the right side of the connecting frame 21 can be opened or closed as needed to facilitate the cleaning and maintenance of the pretreatment component 2. The control valve 24 on the conveying pipe 23 can adjust the ice slurry flow rate in real time, and the refrigeration unit 3 can adjust the refrigeration power according to the quick-freezing requirements to ensure that the equipment is always in a high-efficiency and stable working state.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
