Description

Technical Field

[0001] This utility model relates to the field of quick-frozen food production technology, specifically to a quick-frozen food ice-coating device. Background Technology

[0002] Frozen foods are low-temperature products made from fresh ingredients, which are then properly processed and flash-frozen and delivered to consumers under a continuous low temperature condition of -18°C to -20°C. With rapid economic development and the increasingly fast pace of life, the demand for frozen foods has surged. Currently, in order to better preserve the freshness of frozen foods, they are usually coated with an additional layer of ice to maintain their original flavor.

[0003] Existing equipment uses a single-stage filter to filter circulating ice water, which cannot remove tiny suspended matter, including protein debris and lipid particles. These impurities adhere to the food surface with the ice water and form a cloudy ice coating after freezing. This not only reduces the product's appearance but also makes the ice layer more prone to cracking during transportation. Currently, mainstream immersion-type ice coating machines rely on conveyor belts to transport food through the ice water tank. The food is in a passive and static state, resulting in insufficient ice coating coverage on some irregularly shaped foods and significant fluctuations in ice coating thickness.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an ice-coating device for quick-frozen food, which has the following beneficial effects:

[0017] The rotary table, equipped with symmetrical filter frames and scrapers, efficiently intercepts micron-sized suspended impurities such as protein debris and lipid particles in the circulating ice water. The alternating operation of the dual filters ensures continuous filtration, effectively preventing impurities from adhering to food with the ice water, resulting in higher purity ice water. This makes the final frozen ice coating more transparent and smooth, significantly improving the product's appearance. At the same time, the ice layer structure formed by the pure ice water is more uniform and dense, with stronger adhesion, greatly reducing the risk of ice layer cracking due to stress concentration caused by impurities during subsequent transportation and storage. Three sets of symmetrically distributed nozzles form a wide and uniform spray curtain, while the push rod of the top feeding mechanism precisely acts on the bottom of the food on the conveyor belt, applying a pushing force to the key ice-coating area, causing the food to be slightly lifted, rolled, or shifted. This active intervention breaks the static state of food passively passing through the ice water tank on the mesh belt in traditional immersion equipment. Especially for irregularly shaped foods, it can effectively ensure that all surfaces, especially the bottom and side grooves, can fully and evenly contact the ice water spray, significantly reducing blind spots in ice coating and obtaining a high-quality ice coating of consistent thickness.

Detailed Implementation

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Figures 1-7In one embodiment of this utility model, a quick-frozen food ice-coating device includes a base 1 and a conveyor belt 2. A mounting frame 3 is provided on the base 1, and a water inlet pipe 4 is fixedly mounted on the mounting frame 3. Three sets of nozzles 5 are provided on the base 1, with the two side nozzles 5 symmetrically distributed about the middle nozzle 5. The three sets of nozzles 5 are fixedly connected to the mounting frame 3 via connecting pipes 6. A filtering mechanism 7 is provided inside the mounting frame 3. A positioning frame 8, corresponding to the nozzles 5, is provided on the base 1, and a material-lifting mechanism 9 is provided on the positioning frame 8. The filtering mechanism 7 includes a turntable 701 rotatably mounted on the mounting frame 3. The turntable 701 is rotatably connected to the mounting frame 3 via a mounting shaft 702. A first gear 703 is sleeved on the mounting shaft 702. A first rack 704 is slidably installed inside the mounting frame 3, and the first rack 704 meshes with a first gear 703. A cylinder 705 is fixedly installed inside the mounting frame 3, and the first rack 704 is fixedly connected to the output end of the piston rod of the cylinder 705. Two sets of symmetrically distributed filter frames 706 are embedded on the turntable 701, and each set of filter frames 706 has two sets of symmetrically distributed slots 707. Two sets of retaining rings 708 symmetrically distributed about the turntable 701 are slidably installed inside the mounting frame 3. The retaining rings 708 are correspondingly set with the slots 707, and the two sets of retaining rings 708 are movably engaged with the turntable 701 through the corresponding slots 707. A fixing frame 711 is fixedly installed on the mounting frame 3, and a sliding mounting bracket 711 is mounted on the fixing frame 711. Equipped with a slide 712, the slide 712 contains two sets of scrapers 716 symmetrically distributed about the turntable 701. The scrapers 716 are fitted against the surface of the filter frame 706. The top material mechanism 9 includes a push rod 904, which is fitted against the inner surface of the conveyor belt 2. The turntable 701 is fitted with symmetrical filter frames 706 in conjunction with the scrapers 716, which can efficiently intercept micron-sized suspended impurities such as protein debris and lipid particles in the circulating ice water. The alternating working mode of the dual filters ensures continuous filtration, effectively preventing impurities from adhering to food with the ice water, obtaining ice water with higher purity, and making the ice coating formed by final freezing more transparent and smooth, significantly improving the product's appearance. At the same time, the ice layer structure formed by pure ice water is more uniform and dense. It has stronger adhesion, which greatly reduces the risk of ice layer cracking caused by stress concentration of impurities during subsequent transportation and storage. The three sets of nozzles 5 are symmetrically distributed to form a wide and uniform spray curtain, while the push rod 904 of the top material mechanism 9 acts precisely on the bottom of the food on the conveyor belt 2, applying a pushing force in the key ice-coating area, causing the food to be slightly lifted, rolled or deviated. This active intervention breaks the static state of food that only passively passes through the ice water tank on the mesh belt in traditional immersion equipment. Especially for irregularly shaped foods, it can effectively ensure that all surfaces, especially the bottom and side grooves, can fully and evenly contact the ice water spray, significantly reducing the ice coating blind spots and obtaining a high-quality ice coat with consistent thickness.

[0029] In this embodiment, reference Figures 3-6As shown, telescopic tubes 709 are provided between the two sets of retaining rings 708 and the mounting bracket 3. The two ends of the telescopic tubes 709 are fixedly connected to the mounting bracket 3 and the retaining rings 708, respectively. A bidirectional screw 905 is rotatably installed inside the mounting bracket 3, and both ends of the bidirectional screw 905 pass through the two sets of retaining rings 708 and are threadedly connected to the two sets of retaining rings 708, respectively. Two sets of symmetrically distributed first sliding rods 713 are fixedly installed on the fixing bracket 711, and the sliding seat 712 is slidably sleeved with the first sliding rods 713. Two sets of symmetrically distributed first springs 714 are sleeved on the first sliding rods 713, and the two ends of the first springs 714 are respectively connected to the sliding seat 712. A fixed frame 711 is fixedly connected to the slide block 712. A first cam 715 is rotatably mounted inside the fixed frame 711, and the first cam 715 is fitted against the slide block 712. Both sets of scraper brushes 716 are rotatably connected to the slide block 712 via a rotating rod 717. A second gear 718 is sleeved on the rotating rod 717. A second rack 719 is slidably mounted inside the slide block 712, and the second rack 719 is meshed with the second gear 718. A flying disc 721 is rotatably mounted inside the slide block 712, and a connecting rod 720 is provided between the flying disc 721 and the second rack 719. The two ends of the connecting rod 720 are respectively connected to the second rack 719 and the flying disc 716 via a rotating shaft. 21 Rotary connection, circulating ice water is injected into the system through the inlet pipe 4, first entering the rotary dual-screen filter mechanism in the mounting bracket 3. The cylinder 705 drives the first rack 704 to move linearly, driving the meshing first gear 703 to rotate, thereby causing the turntable 701 to rotate 180° around the mounting shaft 702, switching the working state of the two symmetrically distributed filter screens, one for filtering and the other for cleaning. When one set of filter screens intercepts impurities such as protein debris and lipid particles, the slide seat 712 on the fixed bracket 711 is periodically squeezed by the first cam 715 and slides back and forth along the first slide rod 713, cooperating with the first spring 71 on the first slide rod 713. 4. The slide block 712 drives the two sets of scraper brushes 716 to slide back and forth against the filter screen surface. At the same time, the motor in the slide block 712 drives the flyboard 721 to rotate. With the help of the connecting rod 720, the second rack 719 slides back and forth in the slide block 712. With the help of the second gear 718, the rotating rod 717 drives the two sets of scraper brushes 716 to swing back and forth on the surface of the filter frame 706 to scrape off impurities and prevent clogging. The filtered pure ice water is transported to the three sets of nozzles 5 through the connecting pipe 6. The pure ice water passes through the three sets of nozzles 5 that are symmetrically distributed. The nozzles on both sides are angled towards the center, and the nozzle in the middle is vertically downward, forming a uniform water curtain that covers the food surface on the conveyor belt 2.

[0030] In this embodiment, reference Figure 7As shown, the top material mechanism 9 includes a mounting rod 901 slidably mounted on the positioning frame 8, and a first adjusting rod 902 slidably mounted inside the mounting rod 901. A second adjusting rod 903 slidably mounted inside the first adjusting rod 902, with one end of the second adjusting rod 903 away from the mounting rod 901 fixedly connected to a push rod 904. The push rod 904 is correspondingly positioned with the intermediate nozzle 5. A second sliding rod 909 is fixedly mounted inside the positioning frame 8. A screw 905 is rotatably mounted inside the mounting rod 901. A screw rod 905 passes through and is threadedly connected to the first adjusting rod 902. A screw tube 907 is rotatably installed inside the first adjusting rod 902, and the screw tube 907 passes through and is threadedly connected to the second adjusting rod 903. Two sets of symmetrically distributed keyways 906 are provided on the screw rod 905. Two sets of symmetrically distributed key blocks 908 are provided inside the screw tube 907, and the key blocks 908 are correspondingly arranged with the keyways 906. The screw tube 907 is connected to the screw rod 905 through the key blocks 908 and the keyways 906. The mounting rod 901 and the second slide rod 909 are slidably sleeved together. Two sets of symmetrically distributed second springs 910 are sleeved on the second slide rod 909, and the two ends of the two sets of second springs 910 are respectively fixedly connected to the mounting rod 901 and the positioning frame 8. A cam is rotatably mounted on the positioning frame 8, and the cam is set to fit against the mounting rod 901. When the food moves with the conveyor belt 2 to below the middle nozzle 5, the second cam 911 on the positioning frame 8 pushes the mounting rod 901 along the second slide rod 909. 9. Moving upwards, the mounting rod 901, through multi-stage adjusting rods, namely the first adjusting rod 902 and the second adjusting rod 903, precisely lifts the push rod 904, making it adhere to the inner surface of the conveyor belt 2 and push the food upwards. The food is partially lifted, slightly rolled or shifted, exposing the bottom and side concave surfaces, and simultaneously receiving ice water spray from three sets of nozzles 5, completely eliminating the dead corners of ice coating. After the second cam 911 rotates past its apex, the second spring 910 pushes the mounting rod 901 and the push rod 904 back to their original positions to avoid interfering with subsequent food processing.

[0031] In this embodiment, circulating ice water is injected into the system through the inlet pipe 4. It first enters the rotary dual-screen filter mechanism in the mounting frame 3. The cylinder 705 drives the first rack 704 to move linearly, which in turn drives the meshing first gear 703 to rotate. This causes the turntable 701 to rotate 180° around the mounting shaft 702, switching the working state of the two symmetrically distributed filter screens. One screen filters, while the other is waiting to be cleaned. When one set of filter screens intercepts impurities such as protein debris and lipid particles, the slide seat 712 on the fixed frame 711 is periodically squeezed by the first cam 715 and slides back and forth along the first slide rod 713. With the help of the first spring 714 on the first slide rod 713, the slide seat 712 drives the two sets of scraper brushes 716 to slide back and forth against the filter screen surface. At the same time, the motor in the slide seat 712 drives the fly disk 721 to rotate. With the help of the connecting rod 720, the second rack 719 slides back and forth in the slide seat 712. With the help of the second gear 718, the rotating rod 717 drives the two sets of scraper brushes 716 to slide against the filter screen surface. The surface of frame 706 oscillates back and forth to scrape away impurities and prevent clogging. The filtered pure ice water is transported to three sets of nozzles 5 through connecting pipe 6. The pure ice water passes through three symmetrically distributed sets of nozzles 5, with the two side nozzles 5 angled towards the center and the middle nozzle 5 pointing vertically downward, forming a uniform water curtain that covers the food surface on conveyor belt 2. When the food moves with conveyor belt 2 to below the middle nozzle 5, the second cam 911 on positioning frame 8 pushes the mounting rod 901 upward along the second slide rod 909. The mounting rod 901, through multi-stage adjusting rods, namely the first adjusting rod 902 and the second adjusting rod 903, precisely lifts the push rod 904, making it adhere to the inner surface of conveyor belt 2 and push the food upward. The food is partially lifted, slightly rolled or shifted, exposing the bottom and side concave surfaces, and simultaneously receiving ice water spray from the three sets of nozzles 5, completely eliminating the dead corners of ice coating. After the second cam 911 rotates past its apex, the second spring 910 pushes the mounting rod 901 and push rod 904 back to their original positions to avoid interfering with subsequent food.
