A production refrigeration and freezing plant

Abstract

This invention relates to the field of freezing technology and discloses a refrigeration and freezing equipment for production, including a heat dissipation and ventilation plate, a main body, a control panel, and a sealed door. In this invention, the production product is suspended at the lower end of the suspension mechanism. After the cold air is filled in the channel, it is blown from the flow structure to the production product below the suspension mechanism. The cold air flows evenly from the center of the production product in a triangular pattern, thereby uniformly freezing and shaping the outer side of the production product. This keeps the production product in a vertical freezing state, preventing the production product from bending during freezing and shaping, and preventing inconsistent shapes of the production product during freezing. When the cold air blows unevenly around the production product, the production product rotates on the hanger, so that the three flow structures evenly blow cold air around the production product and freeze and shape it. This avoids uneven freezing and shaping of the production product, which would cause temperature differences, prevent uneven moisture migration from the production product and promote microbial growth, and prevent uneven distribution of cold air around the production product.

Description

Technical Field

[0001] This invention relates to the field of freezing technology, specifically a production refrigeration and freezing equipment. Background Technology

[0002] Frozen forming is a core step connecting heat processing and subsequent processes, and is widely used in food processing, plastic molding and other fields. Frozen forming equipment on the market is mainly divided into three categories: air-cooled, water-cooled and air-cooled water-cooled combined. Air-cooled equipment usually generates airflow through fans or blowers, and freezes and shapes the products by using the low-temperature airflow. Its advantages are simple structure and no need for additional media. Existing technology freezes and shapes the products by placing them in a cold storage room. After the products are frozen and shaped, they are packaged and transported under refrigeration, avoiding the risk of shrinkage and incomplete packaging caused by freezing and shaping after packaging.

[0003] However, when products are placed on a moving tray in the cold storage compartment, the bottom of the products is in contact with the freezing tray. The freezing air generated by the air-cooling system can only act on the surface of the products, which can easily cause differences in freezing temperature in different parts of the products. This can cause the products to curl and bend during freezing and forming, resulting in inconsistent shapes. In addition, the freezing air generated by the air-cooling system will circulate, causing uneven freezing in some areas. When freezing a batch of products, there can be temperature differences in some areas, which can easily lead to uneven migration of moisture inside the products, causing moisture retention and promoting the growth of microorganisms. Summary of the Invention

[0004] The present invention provides a refrigeration and freezing equipment for production, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: A refrigeration and freezing equipment for production includes a heat dissipation and ventilation plate, a main body, a control panel, and a sealed door. The sealed door opens and closes with hinges on the side of the main body. The control panel is disposed on the surface of the main body. The side of the main body is provided with a heat dissipation and ventilation plate for heat dissipation. The main body includes a housing, a refrigeration unit, a molding mechanism, a controller, a base, a slide, and an air duct. The refrigeration unit and the controller are respectively installed inside the housing, and the controller controls the refrigeration unit through electrical signals from the control panel. The output end of the refrigeration unit is connected to an air duct fixed to the top of the housing. The base is fixed to the bottom of the housing, and the slide slides on the surface of the base. The plane of the slide has vertically arranged molding mechanisms, and the upper end of the molding mechanism is connected to the lower side of the air duct for pipe connection. The forming mechanism includes a guide cone, a sealing tube, a branching tube, a suspension mechanism, a flow structure, a support tube, and an elastic mechanism. The sealing tube is located inside the branching tube and has airflow channels between them. The upper ends of the sealing tube and the branching tube are respectively fixed to the lower ends of the guide cone and the support tube, and the outer side of the guide cone is connected to the channel on the outer side of the sealing tube. The suspension mechanism is spirally fixed to the lower end of the guide cone at the central axis position of the sealing tube. The upper end of the support tube is elastically connected to the lower side of the air duct through the elastic mechanism, and the cold air generated by the refrigeration unit flows through the elastic mechanism to the channel on the outer side of the sealing tube. The flow structure is arranged and distributed inside the sealing tube, and the cold air disperses and flows from the flow structure to the central axis position of the sealing tube in the channel, so as to freeze and form the production product suspended on the suspension mechanism.

[0006] A preferred technical solution: The suspension mechanism includes a connecting frame, a concave cylinder, a spring rod, and a hanger. The spring rod is symmetrically fixed inside the concave cylinder. The connecting frame elastically stretches the spring rod. The lower end of the connecting frame is provided with a hanger for suspending the manufactured products, and the manufactured products elastically drive the connecting frame to stretch the spring rod downward.

[0007] A preferred technical solution: The hanger is provided with a blocking block, a central rod, a housing and a bearing ring. The central rod at the upper end of the housing rotates within the bearing ring. The bearing ring is fixed to the lower end of the connecting frame. The blocking block is fixed inside the housing in an open shape, and the upper end of the manufactured product is engaged and fixed between the blocking blocks.

[0008] A preferred technical solution: The elastic mechanism has a circular opening, a lower base plate, an upper base plate, and a spring. The upper and lower ends of the spring are respectively connected to the upper base plate and the lower base plate. The circular opening is located at the lower end of the air duct and corresponds to the upper base plate. The lower base plate is fixed to the upper end of the support pipe. The spring has a rubber ring for sealing between the corresponding lower base plate and the upper base plate. The elasticity of the spring drives the pipe at the lower end of the circular opening of the upper base plate to connect.

[0009] A preferred technical solution: The flow structure is provided with a guide plate, a barrier and a frame plate. The guide plate is connected between two frame plates. The frame plate is located inside the sealing tube. A guide plate is provided between the barrier to guide the cold air and to disperse the cold air. The guide plates on the three sealing tubes are distributed in a triangle and guide the cold air to blow towards the central axis.

[0010] Compared with existing technologies, this technical solution has the following advantages: In this invention, the manufactured product is suspended at the lower end of the suspension mechanism. After cold air flows from the air duct to the forming mechanism, the cold air fills the channel and blows from the flow structure to the manufactured product below the suspension mechanism. The cold air flows evenly to the middle of the manufactured product in a triangular shape, thereby uniformly freezing and forming the outer side of the manufactured product. By freezing the manufactured product while it is suspended, the manufactured product is kept in a vertical position during freezing, which avoids the manufactured product from bending during freezing and prevents the manufactured product from having an inconsistent shape during freezing.

[0011] In this invention, when the cold air blows unevenly around the product, the product rotates on the hanger, so that the three flow structures blow cold air evenly around the product and freeze it, avoiding uneven freezing and forming of the product and causing temperature differences, preventing uneven moisture migration from the product and promoting microbial growth, and avoiding uneven distribution of cold air around the product.

Detailed Implementation

[0021] like Figures 1 to 7 As shown, the present invention proposes a refrigeration and freezing equipment for production, including a heat dissipation and ventilation plate 1, a main body 2, a control panel 3 and a sealing door 4. The sealing door 4 is hinged to open and close on the side of the main body 2. The control panel 3 is disposed on the surface of the main body 2. The heat dissipation and ventilation plate 1 for heat dissipation is disposed on the side of the main body 2. The main body 2 includes a housing 21, a refrigeration unit 22, a molding mechanism 23, a controller 24, a base 25, a slide 26, and an air duct 27. The refrigeration unit 22 and the controller 24 are respectively installed inside the housing 21, and the controller 24 controls the refrigeration unit 22 through electrical signals from the control panel 3. The output end of the refrigeration unit 22 is connected to the air duct 27 fixed to the top of the housing 21. The base 25 is fixed to the bottom of the housing 21. The slide 26 slides on the surface of the base 25. The molding mechanism 23 is arranged vertically on the plane of the slide 26, and the upper end of the molding mechanism 23 is connected to the lower side of the air duct 27. The forming mechanism 23 includes a flow-guiding cone 231, a sealing tube 232, a bifurcated tube 233, a suspension mechanism 234, a flow structure 235, a support tube 236, and an elastic mechanism 237. The sealing tube 232 is located inside the bifurcated tube 233 and has air circulation channels between them. The upper ends of the sealing tube 232 and the bifurcated tube 233 are respectively fixed to the lower ends of the flow-guiding cone 231 and the support tube 236, and the outer side of the flow-guiding cone 231 is connected to the channel on the outer side of the sealing tube 232. The suspension mechanism 234... The sealing tube 232 is spirally fixed at the lower end of the flow cone 231 at the central axis position. The upper end of the support tube 236 is elastically connected to the lower side of the air duct 27 through the elastic mechanism 237, so that the cold air generated by the refrigerator 22 flows through the elastic mechanism 237 to the outer channel of the sealing tube 232. The flow structure 235 is arranged and distributed inside the sealing tube 232, and the cold air flows from the flow structure 235 to the central axis position of the sealing tube 232 in the channel, so as to freeze and shape the production product suspended on the suspension mechanism 234.

[0022] Furthermore, the size of the channel between the sealing tube 232 and the branch tube 233 is half that of the production product, and the bottom of the branch tube 233 is connected to the bottom of the sealing tube 232, which has the effect of filling the entire channel gap with cold air. A sponge block is provided on the side of the bottom of the channel. The sponge block absorbs the water condensed by the cold air at the bottom and overflows out of the branch tube 233, so as to avoid the accumulation of water condensed by the cold air at the bottom and affecting the flow of cold air.

[0023] Furthermore, the drainage cone 231 has holes around its periphery for circulation. The refrigeration unit 22 generates cold air and allows it to circulate through the air duct 27. After opening the sealing door 4, the slide 26 is pulled to move laterally out of the base 25, thereby suspending the manufactured product in the forming mechanism 23 on the slide 26. The slide 26 is then pushed into the air duct 27 again, so that the base 25 aligns with the pipe below the air duct 27. During pipe alignment, the elastic mechanism 237 elastically squeezes the lower end of the air duct 27, preventing cold air leakage while facilitating the pull-out of the slide 26.

[0024] In this invention, the manufactured product is suspended at the lower end of the suspension mechanism 234. After cold air flows from the air duct 27 to the forming mechanism 23, the cold air flows through the holes into the channel between the sealing pipe 232 and the branch pipe 233. After the cold air fills the channel, it blows from the flow structure 235 to the manufactured product below the suspension mechanism 234. The cold air flows evenly to the middle of the manufactured product in a triangular shape, thereby uniformly freezing and forming the outer side of the manufactured product. By freezing the manufactured product while it is suspended, the manufactured product is kept in a vertical position during freezing, which avoids the manufactured product from bending during freezing and prevents the manufactured product from having an inconsistent shape during freezing.

[0025] The suspension mechanism 234 includes a connecting frame 2341, a concave cylinder 2342, a spring rod 2343, and a hanger 2344. The spring rod 2343 is symmetrically fixed inside the concave cylinder 2342. The connecting frame 2341 elastically stretches the spring rod 2343. The lower end of the connecting frame 2341 is provided with a hanger 2344 for suspending the production products, and the production products elastically drive the connecting frame 2341 to stretch the spring rod 2343 downward.

[0026] Furthermore, the hanger 2344 is located at the central axis of the concave cylinder 2342. When the product is suspended on the hanger 2344, the weight of the product will cause the connecting frame 2341 to pull the spring rod 2343 downward. Thus, the suspended product can move elastically under the elastic force of the spring rod 2343, which facilitates the shaking off of moisture from the outside of the product and prevents moisture from forming ice blocks on the outside of the product during freezing.

[0027] The hanger 2344 is provided with a blocking block 441, a central rod 442, a housing 443 and a bearing ring 444. The central rod 442 at the upper end of the housing 443 rotates within the bearing ring 444. The bearing ring 444 is fixed to the lower end of the connecting frame 2341. The blocking block 441 is fixed in an open shape inside the housing 443, and the upper end of the manufactured product is engaged and fixed between the blocking blocks 441.

[0028] Furthermore, the bearing ring 444 and the center rod 442 are connected by ball bearings for bearing rotation; the production products suspended on the blocking block 441 are produced products in series, and each production product corresponds to the exit position of 345.

[0029] Furthermore, the uppermost part of the product enters through the opening of the blocking block 441, and the nodes of the product are fixed to the upper end of the blocking block 441, forming a suspension effect on the product. When the product is blown by uneven cold air, the product will rotate within the bearing ring 444 through the central rod 442 at the upper end of the housing 443, thereby causing the suspended product to rotate, which facilitates uniform freezing and forming by cold air and prevents uneven cold air from causing differences in freezing temperature in different areas of the product.

[0030] The elastic mechanism 237 includes a circular opening 2371, a lower base plate 2372, an upper base plate 2373, and a spring 2374. The upper and lower ends of the spring 2374 are respectively connected to the upper base plate 2373 and the lower base plate 2372. The circular opening 2371 is located at the lower end of the air duct 27 and corresponds to the upper base plate 2373. The lower base plate 2372 is fixed to the upper end of the support pipe 236. The spring 2374 has a rubber ring for sealing between the lower base plate 2372 and the upper base plate 2373. The elasticity of the spring 2374 drives the pipe at the lower end of the upper base plate 2373 corresponding to the circular opening 2371 to connect.

[0031] Furthermore, the upper end of the upper base 2373 is tilted outwards, and its tilted surface has a guiding sliding effect. When the elastic mechanism 237 moves laterally out of the base 25 along with the slide block 26, the upper base 2373 disengages from the matching position of the circular opening 2371. However, when the elastic mechanism 237 enters the lower end of the air duct 27 from the side, the tilted surface of the upper base 2373 guides the lower end of the air duct 27 and compresses the spring 2374, causing the upper base 2373 to match the lower end of the circular opening 2371. At this time, the upper... The base 2373 and the lower base 2372 are sealed and connected by a rubber ring, allowing cold air to flow from the air duct 27 to the upper base 2373 below the circular opening 2371, guiding the cold air to freeze and shape the products suspended inside the forming mechanism 23; at the same time, the upper base 2373 is easily disengaged from the circular opening 2371 by the elasticity of the spring 2374, while preventing cold air from leaking from the lower side of the circular opening 2371 when they are in contact, making it easy for the slide 26 to be moved out.

[0032] The flow structure 235 is provided with a guide plate 2351, a barrier 2352 and a frame plate 2353. The guide plate 2351 is connected between two frame plates 2353. The frame plate 2353 is located inside the sealing tube 232. The guide plate 2351 is provided between the barrier 2352 to guide the cold air and disperse the cold air. The guide plates 2351 on the three sealing tubes 232 are triangularly distributed and guide the cold air to blow towards the central axis.

[0033] Furthermore, the length of the frame plate 2353 is the same as that of a single product. The cold air guided out by the guide plate 2351 on the inner side of each frame plate 2353 is evenly distributed to freeze each product. Even freezing can reduce the difference in moisture evaporation on the surface of the product and ensure the consistency of the product's taste and color. When the product is suspended, it enters the middle position through the gap between the three sealing tubes 232 for suspension.

[0034] In this invention, multiple guide plates 2351 are symmetrically fixed to the inner side of the barrier 2352 at different tilt angles, and the flow structure 235 in the three sealing tubes 232 forms a triangle corresponding to the production product at the center position to disperse and guide cold air, so that the outer periphery of the production product is evenly wrapped by the cold air guided by the three flow structures 235. When the cold air blows unevenly on the outer periphery of the production product, the production product rotates on the hanger 2344, so that the three flow structures 235 evenly blow cold air on the outer periphery of the production product and freeze it, avoiding uneven freezing and forming of the production product by the cold air, which would cause temperature difference, prevent uneven moisture migration of the production product and promote microbial growth, and avoid uneven distribution of cold air on the outer periphery of the production product.

[0035] It should be noted that the product mentioned in this invention is elongated. By freezing and shaping the elongated meat products and other products after heat processing, the shape of the products is ensured to be consistent.

[0036] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
