Description

Technical Field

[0001] The present application relates to the technical field of liquid nitrogen rapid cooling devices for halogen products, and in particular to a liquid nitrogen rapid cooling device for halogen products with a built-in flipping structure. Background Art

[0002] Stewed products are made from meat and viscera of poultry and livestock, some aquatic products and vegetables. They are put into the prepared marinade, boiled over high heat, and simmered over low heat, so that the flavor of the marinade slowly penetrates into the texture of the raw materials, and then become fragrant and delicious stewed products. Stewed products belong to general cooked meat products. They highlight the original taste and color of the raw materials. The seasoning mainly uses salt and a small amount of soy sauce, with its original color, fragrance and taste as the main ingredients. Stewed products are "cooked hot and eaten cold" and taste fresh and fragrant. The prepared marinade can be used for a long time, and the older it is, the more fragrant it is.

[0003] In order to study the rapid freezing of marinated products, reduce water loss, improve product taste, and extend product storage time, research on rapid freezing technology is conducted. The principle of liquid nitrogen vaporization absorbing a large amount of heat is used to quickly cool the product and reach a frozen state in a very short time, thereby locking the moisture in the product and reducing the water loss of the product. It only needs to be thawed before consumption. The frozen state will greatly inhibit the activity of microorganisms and can also greatly increase the storage time.

[0004] However, during the transportation and freezing process, some products are still frozen unevenly, which needs further improvement.

[0005] To this end, the present application proposes a liquid nitrogen rapid cooling device for halogenated products with a built-in flipping structure. Utility Model Content

[0006] The present application proposes a liquid nitrogen rapid cooling device for marinated products with a built-in flipping structure to solve the problems raised in the above-mentioned background technology; by setting up a flipping mechanism, when the product is placed on the conveyor mesh belt, the mesh belt will run slowly, so that the product can be continuously frozen through the freezing zone, continuous freezing can be achieved, and freezing efficiency is improved. During the product conveying process, when the product is conveyed to the middle section of the conveyor mesh belt, the product on the conveyor mesh belt will enter the groove of the flip plate through the inclined plate, and the motor will drive the half of the main gear to rotate. The engagement of the half of the main gear with the slave gear will prompt the rotating rod connected to it to rotate, and the rotating rod will drive the flip plate to rotate 180 degrees, thereby turning the product in the groove of the flip plate to the other side, so that the two sides of the product are frozen evenly, and there is no phenomenon of uneven freezing on one side of the conveyor mesh belt, thereby improving the quick freezing effect of the product, ensuring the quality of the product, and greatly improving the practicality of the device.

[0007] In order to achieve the above purpose, this application adopts the following technical solutions:

The nitrogen gas generated during the vaporization of liquid nitrogen will be discharged from the workshop by a strong exhaust fan to ensure the stability of the oxygen content in the workshop.

[0034] Referring to Figures 1-4, The low-temperature liquid nitrogen storage tank 1 is located above the conveyor belt 4. The low-temperature liquid nitrogen storage tank 1 converts the liquid into gas through the vacuum liquid nitrogen pipeline system 2 and transports it to the freezing area 11. By utilizing the principle that liquid nitrogen absorbs a large amount of heat when it converts from liquid to gas at normal temperature and pressure, through the PLC monitoring of the temperature in the product freezing area 11, the liquid nitrogen spraying amount is intelligently controlled, thus enhancing the practicality of the device.

[0035] Refer to Figures 1-4 , The inside of the conveyor belt 4 is provided with a heat-insulating layer 6, and a fan circulation system 5 is arranged inside the conveyor belt 4 and within the heat-insulating layer 6. The circulating fan is used to accelerate the gasification of liquid nitrogen and increase the heat exchange amount of the product, so that the heat taken away by the gasified liquid nitrogen at normal temperature just balances the heat generated by the product in the freezing area 11, maintaining the low-temperature environment temperature in the freezing area 11, thus enhancing the practicality of the device.

[0036] Refer to Figures 1-4 , A turning mechanism 9 is arranged on the conveyor belt 4. The turning mechanism 9 includes a turning plate 91, a groove 92, an inclined plate 93, a connecting rod 94, a roller 95, a rotating rod 96, a motor 97, a half main gear 98, a driven gear 99, and a through hole 10. By setting the turning mechanism 9, both sides of the product are evenly frozen, and there is no phenomenon of uneven freezing on the side located on the conveyor belt 4, thus improving the quick-freezing effect of the product and ensuring the quality of the product, thereby enhancing the practicality of the device.

[0037] Refer to Figures 1-4 , The rotating rod 96 is rotatably connected to the frame of the conveyor belt 4, and the turning plate 91 is fixedly connected above the conveyor belt 4 outside the rotating rod 96. By setting the rotating rod 96 and the turning plate 91, when the rotating rod 96 rotates, the turning plate 91 is driven to rotate 180 degrees through the rotating rod 96. Thus, while flipping the product on one side of the conveyor belt 4 to the other side of the conveyor belt 4, the product in the groove 92 of the turning plate 91 can be flipped to the other side, thereby enhancing the practicality of the device.

[0038] Refer to Figures 3-4 , The inside of the turning plate 91 is provided with a groove 92, and an inclined plate 93 is arranged on the turning plate 91 and at the groove 92. By setting the groove 92 and the inclined plate 93, the inclined plate 93 can better assist the product to smoothly enter the groove 92 in the turning plate 91. The setting of the groove 92 makes the product on the turning plate 91 not easily fall off and affect the flipping, thereby enhancing the practicality of the device.

[0039] Refer to Figures 1-4, a motor 97 is fixedly connected to the frame of the conveying mesh belt 4, the output end of the motor 97 is fixedly connected to a half main gear 98, one end of a rotating rod 96 is fixedly connected to a driven gear 99, and the half main gear 98 is meshed with the driven gear 99; the motor 97 drives the half main gear 98 to rotate, and the meshing of the half main gear 98 and the driven gear 99 will cause the rotating rod 96 connected thereto to rotate. The turnover plate 91 is rotated 180 degrees by the rotating rod 96, so that both sides of the product are evenly frozen, and there is no phenomenon such as uneven freezing on one side of the conveying mesh belt 4, thereby improving the quick-freezing effect of the product, ensuring the quality of the product, and thus enhancing the practicability of the device.

[0040] Refer to Figures 3-4 , a plurality of through holes 10 are opened in the inclined plate 93, and a plurality of connecting rods 94 are rotatably connected inside the turnover plate 91 and below the inclined plate 93. A roller 95 is fixedly connected to the outside of each connecting rod 94, and each roller 95 extends to the surface of the inclined plate 93 through the through hole 10; by providing the through hole 10, the connecting rod 94 and the roller 95, opening the through hole 10 in the inclined plate 93 and arranging the connecting rod 94 and the roller 95 in the turnover plate 91 helps the product to quickly and smoothly enter the groove 92 of the turnover plate 91, thereby enhancing the practicability of the device.

[0041] Working principle: Utilize the principle that liquid nitrogen needs to absorb a large amount of heat when it is converted from a liquid state to a gaseous state under normal temperature and pressure. Through the PLC monitoring of the temperature in the product freezing area 11, the spraying amount of liquid nitrogen is intelligently controlled. At the same time, the circulating fan is used to accelerate the gasification of liquid nitrogen and increase the heat exchange amount of the product, so that the heat taken away by the gasification of liquid nitrogen at normal temperature just balances the heat generated by the product in the freezing area 11, maintaining the low-temperature environment temperature in the freezing area 11. The product is slowly passed through the freezing area 11 by the conveying mesh belt 4 to achieve the effect of continuous freezing. The nitrogen gas generated during the gasification of liquid nitrogen is discharged from the workshop by the forced exhaust fan to ensure the stability of the oxygen content in the workshop.

[0042] When the product is placed on the conveyor mesh belt 4, the mesh belt will run slowly, so that the product can pass through the freezing area continuously for freezing, realizing continuous freezing and improving the freezing efficiency. During the product conveying process, when the product is conveyed to the middle section of the conveyor mesh belt 4, at this time, by setting the flipping mechanism 9, the product on the conveyor mesh belt 4 will enter the groove 92 of the flipping plate 91 through the inclined plate 93. By opening through holes 10 in the inclined plate 93 and arranging connecting rods 94 and rollers 95 in the flipping plate 91, it helps the product to quickly and smoothly enter the groove 92 of the flipping plate 91. When the product is located in the groove 92 of the flipping plate 91, the motor 97 drives the half main gear 98 to rotate. The engagement of the half main gear 98 with the slave gear 99 will cause the connecting rotating rod 96 to rotate. The rotating rod 96 drives the flipping plate 91 to rotate 180 degrees. Thus, while flipping the product on one side of the conveyor mesh belt 4 to the other side of the conveyor mesh belt 4, the product in the groove 92 of the flipping plate 91 can be flipped to the other side, making both sides of the product freeze evenly, and there is no phenomenon of uneven freezing on the side located on the conveyor mesh belt 4, thereby improving the quick-freezing effect of the product and ensuring the quality of the product.
