Description

Technical Field

[0001] This invention relates to the field of surimi processing technology, specifically to a refrigeration device and refrigeration method for processing surimi products. Background Technology

[0002] Surimi products are a type of high-protein, elastic, and smooth gelatinous food made primarily from fish meat through processes such as meat extraction, washing, pounding, seasoning, shaping, and gelation. The most common surimi product is fish balls. In its processing, quick-freezing is a crucial preservation step: after shaping and cooking, the products are rapidly transferred to a quick-freezing device, passing through the maximum ice crystal formation zone in a very short time, causing the core temperature to drop rapidly to below -18°C, thus effectively locking in the fresh, elastic texture and flavor. After quick-freezing, the products are usually neatly stacked on trays in low-temperature refrigerated cabinets (or freezers) for temporary storage in a constant freezing environment to avoid temperature fluctuations. When it's time to ship, the trays are removed from the refrigerated cabinets, packaged or boxed according to specifications, and then immediately loaded into refrigerated trucks or other cold chain transportation vehicles, maintaining a low temperature environment below -18°C throughout the journey until delivery to the sales terminal or consumer.

[0003] After the fish balls are quick-frozen, they are usually neatly arranged on trays and placed in refrigerated cabinets. Because the fish balls are often close together, if the spacing is too small or they are in contact with each other, they may stick together. Furthermore, the surface of the fish balls on the tray still contains unfrozen moisture. At the low temperature, this moisture quickly forms ice crystals in areas close to adjacent fish balls, easily freezing them together. Simultaneously, the unfrozen moisture on the surface of the fish balls also seeps into and spreads onto the tray surface. As the center temperature continues to drop, this water freezes between the fish balls and the tray, causing the fish balls to stick tightly to the tray. Whether the fish balls freeze into a clump together or stick to the tray, it severely damages the product's shape, making it difficult to remove from the tray, causing breakage and crumbling, and affecting subsequent packaging and the product's appearance. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigeration device and method for processing surimi products, which has the advantage of separating and arranging the fish balls to prevent them from sticking together.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a refrigeration device for processing surimi products, comprising a refrigeration cabinet, and further comprising: A grid-type pallet mechanism, comprising several units, is installed inside the refrigerated cabinet. The grid-type pallet mechanism includes a pallet body, rotating rollers, and a second stop bar. The rotating rollers are rotatably connected to the pallet body, and there are several rotating rollers arranged in pairs. The two rotating rollers in the same pair are connected by a transmission mechanism. The second stop bar and the rotating rollers form multiple grids on the surface of the grid-type pallet mechanism. A slide rail mechanism is located inside the refrigerator cabinet and is used to support the mesh tray mechanism inside the refrigerator cabinet.

[0006] Preferably, the grid tray mechanism further includes: The first gear set, which consists of several sets, is composed of two meshing spur gears of the same size, and the two spur gears in the first gear set are used for the transmission of power between the two rotating rollers in the same set; The main rotating rod is fixed to the interior of the tray body via a bearing seat; The second gear set, consisting of two meshing bevel gears, is used to transmit power between the main rotating rod and the rotating roller; A transmission gear is bolted to the end of the main rotating rod; The cooling-type propulsion component drives the transmission gear to rotate when the interior of the refrigerated cabinet is cooled. The recirculation component, acting as a bridge between the cooled propulsion component and the second lever, transfers cold energy back to the second lever outside the refrigerator cabinet.

[0007] Preferably, the rotating roller is composed of a roller body and a silicone sleeve, and two roller bodies are a group. The roller bodies are rotatably connected to the tray body. The two spur gears in the first gear set are respectively fixed to the ends of the two roller bodies in the same group. The two bevel gears in the second gear set are respectively fixed to the surface of the main rotating rod and the end of the roller body.

[0008] Preferably, a first stop bar is also bolted to the inner side of the pallet body. The height of the first stop bar is higher than the height of the roller body, and the first stop bar is located above the two sets of roller bodies.

[0009] Preferably, the cooled propulsion assembly includes: A long cylinder is bolted to the inside of the tray body. A piston is slidably connected to the inner wall of the long cylinder. The space on one side of the piston in the long cylinder stores a cold expansion medium, and the cold expansion medium occupies 60% to 70% of the internal space of the long cylinder. A movable rod is bolted to the piston and extends to the outside of the long cylinder; A long rack is located below the long cylinder, and a movable sleeve that is slidably connected to the surface of the long cylinder is also attached to the end of the long rack. The long rack meshes with the transmission gear. The connecting blocks are respectively bolted to the end of the movable rod and the surface of the long rack; A ring body, bolted to the surface of the long cylinder; The first copper pillar penetrates the surface of the long cylinder, with one end extending to the outside of the tray body; An elastic element is used to apply a force toward the first copper pillar to the movable rod.

[0010] Preferably, the cold expansion medium inside the long cylinder is water, and the length of the teeth on the surface of the long rack is greater than 10% of the length of the space occupied by the cold expansion medium.

[0011] Preferably, the surface of the elongated cylinder is further welded with a raised strip, and the inner wall of the movable sleeve is provided with a groove that is slidably connected to the surface of the raised strip.

[0012] Preferably, the elastic element is a compression spring, and the compression spring is sleeved on the surface of the long cylinder, with its two ends in contact with the movable sleeve and the ring respectively.

[0013] Preferably, the recirculation assembly consists of a connecting pipe and a second copper pillar. The connecting pipe is a metal tube with both ends closed. There are several connecting pipes, corresponding to the number of the second stop levers. The end of the connecting pipe away from the long cylinder is in contact with the end of the second stop lever. The end of the connecting pipe is embedded in the outer surface of the long cylinder, and the embedded part is located on the side of the long cylinder surface away from the elastic element. The second copper pillar passes through the end of the connecting pipe where it is embedded in the long cylinder. The interior of the connecting pipe stores a cooling medium.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a grid-type tray mechanism to form multiple independent holding grids by interlacing several rotating rollers and second stop bars. A first stop bar is set above the adjacent two sets of roller bodies to block the invalid grids. When loading the tray, the frozen fish balls only need to be poured onto the tray body and flattened, and the fish balls will fall into the effective grids. Each grid can only hold a single fish ball, avoiding the problem of fish balls sticking together caused by traditional dense plating.

[0015] 2. In this invention, the long cylinder of the cooled propulsion assembly absorbs the cold energy inside the refrigerator through the first copper column, causing the water inside the cylinder, which acts as a cold expansion medium, to gradually freeze and expand in volume. This drives the piston and movable rod to move, which in turn drives the long rack to move smoothly in a straight line through the connecting block. This drives the main rotating rod to rotate by meshing with the transmission gear. The main rotating rod is driven by the bevel gears and spur gears of the second gear set and the first gear set, which work together to make the two roller bodies of each set slowly rotate relative to each other. This continuously breaks the ice crystal connection between the fish balls and the tray support surface before the water film forms a frozen ice bridge, preventing the fish balls from cold-welding and sticking to the container. Moreover, the relatively rotating silicone sleeve gently drives the fish balls in each grid to rotate through friction, so that the surfaces of the fish balls are in uniform contact with the circulating cold air inside the refrigerator, effectively maintaining and solidifying their spherical shape and preventing local pressure deformation.

[0016] 3. In this invention, the ice that has frozen during the refrigeration stage in the long cylinder serves as a high-density cold source. Its cold energy is efficiently introduced into the low-temperature heat-conducting oil cooling medium in the connecting pipe through the second copper pillar embedded in the metal outer shell of the long cylinder. The cold energy is then conducted to the contact points at the ends of each second lever, keeping the temperature of the second lever itself at an extremely low level. During the brief transfer window when the tray is removed from the refrigerated cabinet, these second levers, which are located around the fish balls and maintain a low temperature, continuously radiate cold energy to the surrounding area, forming a low-temperature barrier in the microenvironment of the fish balls that prevents heat intrusion. This effectively inhibits the surface temperature of the fish balls from rising, serving as an additional insurance against thawing. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-18 As shown, a refrigeration device for processing surimi products includes a refrigeration cabinet 100 and a mesh tray mechanism 300. Several mesh tray mechanisms 300 are arranged inside the refrigeration cabinet 100. Each mesh tray mechanism 300 includes a tray body 310, a rotating roller 320, and a second stop bar 330. The rotating roller 320 is rotatably connected to the tray body 310, and there are several rotating rollers 320 arranged in pairs. Two rotating rollers in the same pair are connected by a transmission mechanism. The second stop bar 330 and the rotating roller 320 form multiple grids on the surface of the mesh tray mechanism 300. Each grid is used to store fish balls. A slide rail mechanism 200 is arranged inside the refrigeration cabinet 100 to support the mesh tray mechanism 300 inside the refrigeration cabinet 100.

[0021] Furthermore, the grid pallet mechanism 300 also includes a first gear set 340, a main rotating rod 350, a second gear set 360, a transmission gear 370, a cooled propulsion assembly 380, and a recooling assembly 390. The first gear set 340 consists of several sets, each composed of two meshing spur gears of the same size. The two spur gears in the first gear set 340 are used for power transmission between two rotating rollers 320 in the same group. The main rotating rod 350 communicates internally with the pallet body 310. Fixed via a bearing housing, the second gear set 360 consists of two meshing bevel gears used to transmit power between the main rotating rod 350 and the rotating roller 320. The transmission gear 370 is bolted to the end of the main rotating rod 350. When the cooling-type propulsion assembly 380 is cooled inside the refrigerator cabinet 100, it drives the transmission gear 370 to rotate. The recooling assembly 390 acts as a bridge between the cooling-type propulsion assembly 380 and the second stop lever 330, and recools the second stop lever 330 from outside the refrigerator cabinet 100.

[0022] Furthermore, the rotating roller 320 is composed of a roller body 321 and a silicone sleeve 322, and the two roller bodies 321 form a group. The roller body 321 is rotatably connected to the tray body 310. The two spur gears in the first gear set 340 are respectively fixed to the ends of the two roller bodies 321 in the same group. The two bevel gears in the second gear set 360 are respectively fixed to the surface of the main rotating rod 350 and the ends of the roller body 321.

[0023] Furthermore, a first stop bar 311 is bolted to the inner side of the tray body 310. The height of the first stop bar 311 is higher than the height of the roller body 321. The first stop bar 311 is located above the two sets of roller bodies 321. This prevents fish balls from falling between the two sets of roller bodies 321. Since the rotation directions of the two roller bodies 321 in the same set are opposite, the fish balls will roll in the middle when the two roller bodies 321 in the same set are rotating in opposite directions. However, if it is between two sets of roller bodies 321, that is, between two roller bodies 321 that are not in the same set, they will be rolled into the grid formed by the fish balls. Therefore, the setting of the first stop bar 311 blocks these ineffective grids. At the beginning of the tray loading process, no fish balls will enter these grids.

[0024] The cooled propulsion assembly 380 includes a long cylinder 381, a movable rod 383, a connecting block 389, a ring 385, a first copper pillar 388, and an elastic element 386. The long cylinder 381 is bolted to the inner side of the tray body 310. A piston 382 is slidably connected to the inner wall of the long cylinder 381. The space in the long cylinder 381 located on one side of the piston 382 stores a cold expansion medium, and this cold expansion medium occupies 60% to 70% of the internal space of the long cylinder 381. The movable rod 383 is bolted to the piston 382 and extends to the outside of the long cylinder 381. A long rack 384 is located below the long cylinder 381, and the end of the long rack 384 is also bolted to the surface of the long cylinder 381. The sliding sleeve 387 and the connecting block 389 are respectively bolted to the end of the movable rod 383 and the surface of the long rack 384. The ring body 385 is bolted to the surface of the long cylinder 381. The first copper pillar 388 penetrates the surface of the long cylinder 381, and one end of it extends to the outside of the tray body 310. The elastic element 386 is used to apply a force to the movable rod 383 toward the first copper pillar 388. The cold expansion medium inside the long cylinder 381 is water. When water is cooled and freezes, its volume expansion rate is about 9%. This 9% expansion is due to the arrangement of water molecules when forming the crystal structure of ice, which makes it occupy a larger volume than when it is in the liquid state, and it is almost incompressible in the liquid state. Therefore, when it forcibly expands by 9%, it can generate amazing thrust. Even a very small amount of water can provide a very considerable driving force for precise movement. Taking a 10 ml energy storage water chamber as an example, after it is completely frozen, it will generate a volume increase of about 0.9 ml. Therefore, after the water is completely frozen, due to the limitation of the long cylinder 381, the increased volume is all applied to the horizontal square of the inner wall of the long cylinder 381, which can push the piston 382 to move. The moving distance is about 60% to 70% × 9% of the internal space of the long cylinder 381 occupied by the cold expansion medium. The length of the teeth on the surface of the long rack 384 is greater than 10% of the length of the space occupied by the cold expansion medium. This is to prevent the teeth on the surface of the long rack 384 from disengaging from the surface of the transmission gear 370 during the movement range of water freezing and expansion.

[0025] Furthermore, since the movable sleeve 387 and the movable rod 383 are on the same central axis on the surface of the long cylinder 381, in order to prevent the movable sleeve 387 from rotating, a protrusion 3811 is welded to the surface of the long cylinder 381. The inner wall of the movable sleeve 387 is provided with a groove 3871 that slides and connects with the surface of the protrusion 3811. During the sliding process of the movable sleeve 387 along the surface of the long cylinder 381, it can drive the groove 3871 to move along the surface of the protrusion 3811, thereby preventing itself from rotating. The elastic element 386 is a compression spring, and the compression spring is sleeved on the surface of the long cylinder 381. Its two ends are in contact with the movable sleeve 387 and the ring 385 respectively. When the water is at room temperature, the reaction force of the compression spring acts on the movable rod 383 through the movable sleeve 387, the long rack 384, and the connecting block 389, causing the movable rod 383 to contract into the interior of the long cylinder 381, compressing the water inside as a cold expansion medium.

[0026] The slide rail mechanism 200 consists of a slide rail body 210 and rollers 220. The slide rail body 210 is bolted to the inner wall of the refrigerator cabinet 100, and there are several rollers 220 that are rotatably connected to the slide rail body 210.

[0027] During use, the quick-frozen fish balls are placed on the surface of the tray body 310. The grid formed by the second stop bar 330 and the roller body 321 is used to place the fish balls one by one. A large number of fish balls can be poured into the tray and then the fish balls are pushed flat. In this way, the fish balls will enter the inside of each grid. Only one fish ball will enter the grid, and the excess will remain on top and be pushed away until all the effective grids are filled with fish balls. Then the tray body 310 is inserted into the slide rail body 210 and contacts the roller 220. Then the refrigerator door is closed for refrigeration. The fish balls are placed separately and are not easy to stick together.

[0028] During the refrigeration process (temperature approximately -18℃), the cold energy is transferred through the first copper column 388 to the interior of the long cylinder 381, and then to the water inside the long cylinder 381, which is the expansion medium. The water gradually absorbs the cold and expands, pushing the piston 382 to move. The piston 382 drives the movable rod 383, the connecting block 389, and the long rack 384 to move. The long rack 384 drives the movable sleeve 387 to move against the force of the elastic element 386. The long rack 384 pushes the teeth on the surface of the transmission gear 370 to rotate, thereby driving the main rotating rod 350 to rotate. The main rotating rod 350 drives one of the multiple roller bodies 321 in the group of multiple roller bodies 321 to rotate (clockwise) through the second gear set 360. Figure 9 (From a certain perspective), then the roller body 321 of this group drives another roller body 321 in the same group to rotate (counterclockwise) through the first gear set 340. Figure 9(From a certain perspective), during the slight rotation of the roller body 321, the roller body 321 in contact with the fish ball is already broken before the water cooling bridge is built, preventing the fish ball from sticking to the silicone sleeve 322 on the surface of the roller body 321. The silicone sleeve 322 is made of food-grade silicone. Moreover, the slight rotation of the roller body 321 causes the water inside the long cylinder 381 to go from room temperature to frozen solid for 8-15 minutes, during which time it continues to expand and drive the roller body 321 to rotate at a speed of 1-5 rpm. This not only prevents it from sticking to the container, but also allows the roller body 321 to drive the fish ball to rotate through the friction of the surface silicone sleeve 322, which helps to maintain the spherical shape of the fish ball.

[0029] The recooling assembly 390 consists of a connecting pipe 391 and a second copper pillar 392. The connecting pipe 391 is a metal tube with both ends closed. There are several connecting pipes 391, which correspond to the number of second stop levers 330. The end of the connecting pipe 391 away from the long cylinder 381 is in contact with the end of the second stop lever 330. The end of the connecting pipe 391 is embedded in the outer surface of the long cylinder 381, and the embedded part is located on the side of the surface of the long cylinder 381 away from the elastic member 386. The second copper pillar 392 passes through the end of the connecting pipe 391 and the long cylinder 381 where they are embedded. The embedded part does not enter the interior of the long cylinder 381, so water will not enter and it will not hinder the piston 382 from moving forward. The interior of the connecting pipe 391 stores a cooling medium, which is a heat transfer oil and a low-temperature synthetic heat transfer oil. Its pour point (referring to the lowest temperature at which the oil can still flow) can reach -50°C or even below -72°C.

[0030] When the tray is removed from the refrigerated container and then packaged or loaded onto a vehicle, the tray body 310 is removed. The frozen ice transfers the cold energy through the outer shell of the long cylinder 381, the second copper pillar 392, and the heat transfer oil. The heat transfer oil itself also absorbs cold energy during the refrigeration process, and the cold energy is then transferred back to the second stop lever 330, keeping the periphery of the second stop lever 330 at a low temperature. This serves as an additional safety measure to prevent the fish balls from thawing during the removal, packaging, or loading of the tray, providing a source of cold energy and achieving continuous refrigeration of the fish balls during short-distance transfers. After the tray is used, it is placed at room temperature, and the frozen water gradually thaws. The piston 382 resets under the action of the elastic element 386, ready for the next refrigeration operation.

[0031] A refrigeration method for processing surimi products, the method comprising the following steps: Step 1: Pour the quick-frozen fish balls onto the tray body 310 of the mesh tray mechanism 300. The mesh formed by the rotating roller 320 and the second stop bar 330 is used to accommodate the fish balls. The fish balls fall into the effective mesh through the pushing operation. Only one fish ball enters each mesh, and the excess fish balls are pushed away. At the same time, the first stop bar 311 located above the two adjacent sets of roller bodies 321 blocks the ineffective mesh to prevent the fish balls from falling into the gap between the rollers, thus achieving single-piece separation arrangement. Step 2: Push the tray body 310, which has been filled, into the refrigerator 100. After the tray is in place, close the refrigerator 100 door. The fish balls are separated in an independent grid and stored in a static refrigerated environment to avoid stacking and squeezing, which is conducive to cold penetration. Step 3: The -18℃ cold energy inside the refrigerated cabinet 100 is introduced into the long cylinder 381 of the cold-receiving propulsion component 380 through the first copper column 388. The water in the long cylinder 381, as a cold expansion medium, gradually freezes and expands, pushing the piston 382 to move. The piston 382 drives the movable rod 383 and the connecting block 389, causing the long rack 384 to move linearly. The long rack 384 meshes with the transmission gear 370 to drive the main rotating rod 350 to rotate. Through the second gear set 360 and the first gear set 340, the two roller bodies 321 of the same set slowly rotate relative to each other. The silicone sleeve 322 on the surface moves slightly at 1 to 5 rpm, breaking the ice bridge at the contact point of the fish ball to prevent adhesion. At the same time, it drives the fish ball to rotate to maintain its spherical shape. This process continues until the water is completely frozen. During this period, the elastic element 386 is compressed and stores energy. Step 4: When removing the tray body 310 for packaging or short-distance transfer, the recooling component 390 intervenes to keep the temperature cold. The ice blocks frozen inside the long cylinder 381 serve as a cold storage body. The cold energy is introduced into the cooling medium in the connecting pipe 391 through the outer shell of the long cylinder 381 and the second copper pillar 392 embedded therein, and is quickly transferred to the part that contacts the end of the second stop lever 330, keeping the second stop lever 330 at a low temperature. During the period when it is removed from the refrigerated cabinet 100, this continuous cold energy inhibits the surface temperature rise of the fish balls, prevents them from thawing and deforming, and plays an additional protective role, achieving continuous refrigeration during the transfer process. Step 5: After use, place the tray at room temperature. The ice inside the long cylinder 381 gradually melts and shrinks in volume. The compressed elastic element 386 releases its elasticity, pushing the movable sleeve 387 to slide along the protrusion 3811 on the surface of the long cylinder 381. Through the connecting block 389 and the movable rod 383, the piston 382 and the long rack 384 are reset. The long rack 384 moves back, causing the transmission gear 370, the main rotating rod 350, each gear set and the roller body 321 to rotate back to their original positions. The entire cooling propulsion assembly 380 returns to its initial state, and the next fish ball refrigeration and traying operation can be carried out.
