Description

Technical Field

[0001] This utility model relates to the technical field of quick-freezing devices, and in particular to a tunnel-type quick-freezing device for quick-frozen food. Background Technology

[0002] Currently, quick-frozen foods are generally frozen rapidly using blast freezing equipment. For example, Chinese utility model patent CN214316900U discloses a reciprocating tunnel device for quick-freezing food. This device includes a quick-freezing box body, an inlet, and an outlet. The inlet is located on the upper left side of the quick-freezing box body, and the outlet is located on the lower left side of the quick-freezing box body. The quick-freezing box body is equipped with a shock-absorbing conveying structure. Through the shock-absorbing conveying structure, the food can be reciprocated, allowing the food to move and cool inside the quick-freezing box body. It also provides shock absorption, ensuring that the food is not subjected to violent impacts and is not damaged.

[0003] However, the aforementioned tunnel-type quick-freezing device uses multiple conveyor belts to move the quick-frozen food back and forth, resulting in a relatively complex conveying structure that occupies a large space. Moreover, there is no separating structure on the conveyor belts, which makes it easy for the food to stick together during the conveying and freezing process. Separating the stuck food later can easily damage the food. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tunnel-type quick-freezing structure that uses a conveyor belt and a mesh plate to reciprocate the conveying of food, which simplifies the conveying structure and reduces food sticking and damage.

[0005] This utility model discloses a tunnel-type quick-freezing device for frozen food, comprising a quick-freezing box, a driving roller, a driven roller, a conveyor belt, and a refrigeration system. The quick-freezing box has a quick-freezing chamber inside, with an inlet and outlet at one end. The driving roller is rotatably mounted inside the quick-freezing chamber, and the driven roller is rotatably mounted outside the inlet and outlet of the quick-freezing box. The conveyor belt is fitted onto the driving and driven rollers. The refrigeration system is installed on the quick-freezing box for cooling the quick-freezing chamber. It also includes multiple separating and pushing components, a mesh plate, and an ice-receiving mechanism. The multiple separating and pushing components are evenly installed... On the outer surface of the conveyor belt, the separating and pushing assembly consists of multiple evenly arranged elastic rods. These multiple separating and pushing assemblies are arranged perpendicular to the conveying direction of the conveyor belt. A mesh plate is installed in the quick-freezing chamber of the quick-freezing box, with its ends extending outside the box through inlets and outlets. The mesh plate is located below the conveyor belt, and the ends of the multiple separating and pushing assemblies scrape the upper surface of the mesh plate. An ice-collecting mechanism is installed inside the quick-freezing chamber, located below the mesh plate, and is used to collect broken ice. The driving and driven rollers rotate to support the conveyor belt, and the multiple separating and pushing assemblies... The conveyor belt is divided into multiple independent cell sections. The refrigeration system creates a low-temperature environment in the blast freezer's freezing chamber. During operation, the food to be blast-frozen is placed sequentially between the multiple separating and pushing components on the conveyor belt. The drive roller drives the conveyor belt to rotate, and the upper surface of the conveyor belt feeds the food into the blast freezer's freezing chamber through the loading / unloading port. When the food reaches the inner end of the conveyor belt, it falls onto the mesh plate. The conveyor belt continues to rotate, causing the multiple separating and pushing components on the lower surface of the conveyor belt to push the food on the mesh plate towards the loading / unloading port of the blast freezer, and then discharge it through the loading / unloading port. The conveyor belt and the mesh plate form a reciprocating blast freezer tunnel. The food is blast-frozen as it moves along the conveyor belt and the mesh plate. The ice fragments generated during the blast freezer fall through the mesh of the mesh plate and are collected in the ice-receiving mechanism, preventing the ice fragments from melting and contaminating the inside of the freezing chamber. Compared with existing technologies, both the upper and lower surfaces of the conveyor belt have the ability to transport food, thereby reducing the number of conveyor belts, simplifying the conveying structure, reducing the space occupied, and using multiple separating and pushing components to form a separating structure to prevent food from sticking and being damaged, thus improving practicality.

[0006] Preferably, it also includes an arc-shaped mesh plate, the lower end of which is installed on the inner end of the mesh plate, and the upper end of which is arranged around the inner end of the conveyor belt. The ends of multiple separating and pushing components scrape the inner surface of the arc-shaped mesh plate. The arc-shaped mesh plate receives and guides the food falling from the inner end of the conveyor belt, and works with multiple separating and pushing components to restrain the food and reduce food damage.

[0007] Preferably, it also includes multiple rollers, which are rotatably installed in the mesh of the wire mesh; the multiple rollers provide rolling support for the food moving on the wire mesh, reducing friction damage to the food.

[0008] Preferably, it also includes multiple protrusions, with multiple protrusions installed on the upper end surface of the mesh plate; the multiple protrusions are used to cause the food to vibrate and bounce when it is conveyed on the mesh plate, shaking off the ice crushes; the multiple separating and pushing components are elastic rods, which will not obstruct the separating and pushing components.

[0009] Preferably, the refrigeration system includes a refrigeration unit and heat dissipation pipes. The refrigeration unit is installed on the quick-freezing box. The inlet end of the heat dissipation pipes is connected to the refrigerant outlet of the refrigeration unit, and the outlet end of the heat dissipation pipes is connected to the refrigerant inlet of the refrigeration unit. The main body of the heat dissipation pipes is arranged on the inner wall of the quick-freezing chamber of the quick-freezing box, and the main body of the heat dissipation pipes is arranged around the conveyor belt and the mesh plate. The arrangement of the main body of the heat dissipation pipes around the conveyor belt and the mesh plate forms a tunnel-like quick-freezing channel, so that the food conveyed on the conveyor belt and the mesh plate is fully refrigerated.

[0010] Preferably, it also includes a fan and a baffle. The fan is installed in the freezing chamber of the quick-freezing box and is located at the inner end of the conveyor belt. The baffle hinge is installed on the loading and unloading port of the quick-freezing box. The operation of the fan causes air to circulate in the freezing chamber of the quick-freezing box, improving the quick-freezing efficiency of food. The baffle reduces the amount of cold air discharged through the loading and unloading port.

[0011] Preferably, the ice-receiving mechanism includes an ice-receiving trough, a scraper, a gate, and a pull rod. The ice-receiving trough is installed below the mesh plate and has an inclined inner bottom surface. A discharge port communicating with the lower end of the inner bottom surface is provided on the side of the ice-receiving trough. The scraper is slidably installed on the inner bottom surface of the ice-receiving trough. The gate is hinged and installed on the discharge port of the ice-receiving trough. The inner end of the pull rod is rotatably connected to the scraper, and the outer end of the pull rod is rotatably connected to the gate. The ice-receiving trough is used to collect ice fragments falling from the conveyor belt and mesh plate, preventing these fragments from contaminating the blast freezer chamber. When ice fragments need to be discharged, the gate is opened outwards, causing the gate to pull the pull rod outwards. The pull rod then pulls the scraper along the inner bottom surface of the ice-receiving trough towards the discharge port, thereby pushing the ice fragments on the inner bottom surface of the ice-receiving trough out of the discharge port, resulting in high ice discharge efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: both the upper and lower surfaces of the conveyor belt have the ability to convey food, thereby reducing the number of conveyor belts, simplifying the conveying structure, reducing the space occupied, and forming a separation structure through multiple separating and pushing components to avoid food sticking and damage, thus improving practicality.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figures 1 to 4As shown, a tunnel-type quick-freezing device for frozen food includes a quick-freezing box 1, a driving roller 2, a driven roller 3, a conveyor belt 4, and a refrigeration system. The quick-freezing box 1 has a quick-freezing chamber inside, with an inlet and outlet at one end. The driving roller 2 is rotatably mounted in the quick-freezing chamber, and the driven roller 3 is rotatably mounted outside the inlet and outlet of the quick-freezing box 1. The conveyor belt 4 is fitted onto the driving roller 2 and the driven roller 3. The refrigeration system is installed on the quick-freezing box 1 for cooling the quick-freezing chamber. The device also includes multiple separating and pushing assemblies 5, a mesh plate 6, and an ice-receiving mechanism 7. The multiple separating and pushing assemblies 5 are evenly mounted on the outer surface of the conveyor belt 4, and each assembly consists of multiple evenly arranged elastic rods. The multiple separating and pushing assemblies 5 are perpendicular to the conveying direction of the conveyor belt 4. The arrangement includes a screen plate 6 installed in the quick-freezing chamber of the quick-freezing box 1, with its ends extending out of the quick-freezing box 1 through inlets and outlets. The screen plate 6 is located below the conveyor belt 4. The ends of multiple separating and pushing components 5 scrape the upper surface of the screen plate 6. An ice-collecting mechanism 7 is installed inside the quick-freezing chamber, located below the screen plate 6, and is used to collect crushed ice. The arrangement also includes an arc-shaped screen plate 8, with its lower end installed on the inner end of the screen plate 6 and its upper end arranged around the inner end of the conveyor belt 4. The ends of multiple separating and pushing components 5 scrape the inner surface of the arc-shaped screen plate 8. The arrangement also includes multiple rollers 9, which are rotatably installed in the mesh of the screen plate 6. The arrangement also includes multiple protrusions 10, which are installed on the upper surface of the screen plate 6.

[0023] The driving roller 2 and driven roller 3 rotate to support the conveyor belt 4. Multiple separating and pushing components 5 divide the conveyor belt 4 into multiple independent cell units. The refrigeration system creates a low-temperature environment in the freezing chamber of the quick-freezing box 1. During operation, the food to be quick-frozen is placed sequentially between the multiple separating and pushing components 5 on the conveyor belt 4. The driving roller 2 drives the conveyor belt 4 to rotate. The upper surface of the conveyor belt 4 feeds the food into the freezing chamber of the quick-freezing box 1 through the loading and unloading port. When the food reaches the inner end of the conveyor belt 4, it falls onto the wire mesh 6. The arc-shaped wire mesh 8 receives and guides the food falling from the inner end of the conveyor belt 4, and works with the multiple separating and pushing components 5 to restrain the food and reduce damage. The conveyor belt 4 continues to rotate, causing the multiple separating and pushing components 5 on the lower surface of the conveyor belt 4 to press against the wire mesh 6. Food is pushed onto the loading / unloading port of the quick-freezing chamber 1. Multiple rollers 9 provide rolling support for the food moving on the mesh plate 6, reducing friction damage to the food, and the food is discharged through the loading / unloading port. The conveyor belt 4 and the mesh plate 6 form a reciprocating quick-freezing tunnel. The food is quick-frozen as it moves on the conveyor belt 4 and the mesh plate 6. Multiple protrusions 10 are used to make the food vibrate and jump when it is conveyed on the mesh plate 6, shaking off the ice fragments. The ice fragments generated during the quick-freezing process fall through the mesh of the mesh plate 6 and are collected in the ice receiving mechanism 7, preventing the ice fragments from melting and contaminating the interior of the quick-freezing chamber. Compared with the prior art, both the upper and lower surfaces of the conveyor belt 4 have the ability to convey food, thereby reducing the number of conveyor belts 4, simplifying the conveying structure, and reducing the space occupied. Multiple separating pusher components 5 form a separating structure to prevent food from sticking and being damaged. Example 2

[0024] like Figures 1 to 3 As shown, based on Embodiment 1, the refrigeration system includes a refrigeration unit 11 and a heat dissipation pipe 12. The refrigeration unit 11 is installed on the quick-freezing box 1. The input end of the heat dissipation pipe 12 is connected to the refrigerant outlet of the refrigeration unit 11, and the output end of the heat dissipation pipe 12 is connected to the refrigerant inlet of the refrigeration unit 11. The main body of the heat dissipation pipe 12 is arranged on the inner wall of the quick-freezing chamber of the quick-freezing box 1, and the main body of the heat dissipation pipe 12 is arranged around the conveyor belt 4 and the mesh plate 6. It also includes a fan 13 and a wind deflector 14. The fan 13 is installed in the quick-freezing chamber of the quick-freezing box 1 and is located at the inner end of the conveyor belt 4. The wind deflector 14 is hinged to the loading and unloading port of the quick-freezing box 1.

[0025] The main body of the heat dissipation pipe 12 is arranged around the conveyor belt 4 and the mesh plate 6 to form a tunnel-like quick-freezing channel, so that the food conveyed on the conveyor belt 4 and the mesh plate 6 is fully cooled. The operation of the fan 13 causes the air to circulate in the quick-freezing chamber of the quick-freezing box 1, thereby improving the quick-freezing efficiency of the food. The cold air is reduced from being discharged through the loading and unloading port by setting the wind baffle 14. Example 3

[0026] like Figure 1 , Figure 2 , Figure 5, Figure 6 and Figure 7 As shown, based on Embodiment 1, the ice-receiving mechanism 7 includes an ice-receiving trough 15, a scraper 16, a gate 17, and a pull rod 18. The ice-receiving trough 15 is installed below the mesh plate 6 and has an inclined inner bottom surface. A discharge port communicating with the lower end of the inner bottom surface is provided on the side of the ice-receiving trough 15. The scraper 16 is slidably installed on the inner bottom surface of the ice-receiving trough 15. The gate 17 is hinged to the discharge port of the ice-receiving trough 15. The inner end of the pull rod 18 is rotatably connected to the scraper 16. The outer end of 8 is rotatably connected to the gate 17; the ice receiving trough 15 is used to receive the broken ice falling from the conveyor belt 4 and the mesh plate 6, so as to prevent the broken ice from contaminating the interior of the quick-freezing chamber of the quick-freezing box 1. When it is necessary to discharge the broken ice, the gate 17 is opened outward, so that the gate 17 pulls the pull rod 18 outward. The pull rod 18 pulls the scraper 16 along the inner bottom surface of the ice receiving trough 15 to the discharge outlet, so that the scraper 16 pushes the broken ice on the inner bottom surface of the ice receiving trough 15 out of the discharge outlet, and the broken ice discharge efficiency is high.

[0027] like Figures 1 to 7 As shown, this utility model discloses a tunnel-type quick-freezing device for frozen food. During operation, the food to be quick-frozen is first placed sequentially between multiple separating and pushing components 5 on a conveyor belt 4. The drive roller 2 drives the conveyor belt 4 to rotate. The upper surface of the conveyor belt 4 feeds the food through the loading / unloading port into the quick-freezing chamber of the quick-freezing box 1. After the food reaches the inner end of the conveyor belt 4, it falls onto a mesh plate 6. The conveyor belt 4 continues to rotate, causing the multiple separating and pushing components 5 on the lower surface of the conveyor belt 4 to push the food on the mesh plate 6 towards the loading / unloading port of the quick-freezing box 1, and then discharge it through the loading / unloading port. Then, the heat dissipation pipe 12 surrounds the conveyor belt 4 and the mesh plate 6 to form a reciprocating quick-freezing tunnel. The food is quick-frozen as it moves on the conveyor belt 4 and the mesh plate 6. The ice fragments generated during the quick-freezing process fall into the ice collection tank 15 through the mesh of the mesh plate 6 to prevent the ice fragments from melting and contaminating the inside of the quick-freezing chamber. When it is necessary to discharge the ice fragments, the gate 17 is opened outward, so that the gate 17 pulls the lever 18 outward. The lever 18 pulls the scraper 16 along the inner bottom surface of the ice collection tank 15 to the discharge outlet, so that the scraper 16 pushes the ice fragments on the inner bottom surface of the ice collection tank 15 out of the discharge outlet.

[0028] The main functions achieved by this utility model are:

[0029] 1. Both the upper and lower surfaces of the conveyor belt 4 have the ability to transport food, thereby reducing the number of conveyor belts 4, simplifying the conveying structure, and reducing the space occupied;

[0030] 2. Multiple separating pusher components 5 form a separating structure to prevent food from sticking and being damaged, thus improving practicality;
