Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and in particular to a high-efficiency quick-freezing device for surimi products. Background Technology

[0002] Chikuwa is a type of surimi product. Its name comes from the process of wrapping fish paste around bamboo skewers during production, ultimately forming a hollow cylinder. The production process of chikuwa includes frying, draining, pre-cooling, and quick-freezing. After frying, a large amount of oil adheres to the outer surface of the chikuwa and accumulates in its inner cavities. Current processing methods typically involve placing the chikuwa statically on a conveyor belt or container for draining and pre-cooling. However, this static processing method has significant drawbacks: 1. Incomplete oil drainage: Relying solely on gravity for natural oil drainage is inefficient, especially for the hollow inner wall of bamboo tubes, where accumulated grease is difficult to remove, resulting in excessively high oil content in the product. Excessive residual grease is prone to oxidative rancidity during subsequent storage, producing a rancid taste and severely affecting the product's flavor and shelf life. 2. Low pre-cooling heat exchange efficiency: During static pre-cooling, a relatively static and high-temperature "insulating air film" (boundary layer) will form on the surface of the bamboo wheel, which hinders heat dissipation, resulting in slow and uneven cooling. Products that are not pre-cooled enough will significantly increase the heat load of the quick-freezing machine, prolong the freezing time, and may cause the product surface to crack due to excessive internal and external temperature differences.

During precooling, the alternating motion mechanism breaks the insulating air film formed on the surface of the bamboo wheel, allowing cold air to always directly contact the product surface, maximizing heat exchange efficiency. Furthermore, the vibration causes the contact point of the core rod to change continuously, ensuring that the entire surface of the bamboo wheel can be evenly contacted by cold air, avoiding problems such as excessively high local temperatures and uneven precooling. The up-and-down vibration also creates a chimney effect inside the bamboo wheel. When the bamboo wheel is lifted, the hot air inside is drawn upwards, and when the bamboo wheel is lowered, the cold air outside is drawn in. This forced air exchange can efficiently remove heat and moisture from deep inside the bamboo wheel, thereby achieving synchronous and rapid cooling from the inside out, greatly improving the precooling effect of the bamboo wheel. 3. The core rod adopts a quick-release and detachable installation structure, which greatly improves the efficiency of loading and unloading bamboo wheels for workers. Attached Figure Description

[0016] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to Figures 1 to 7 The first embodiment of the present invention: A high-efficiency quick-freezing device for surimi products includes a base 1, a freezing tunnel 2, an annular turntable 3, a partition 4, a core rod 5, an alternating motion mechanism 6, and a drive mechanism 9. The freezing tunnel 2 has a ring-shaped structure. Inside the freezing tunnel 2, there are oil draining area, pre-cooling area and quick-freezing area in sequence. The two ends of the freezing tunnel 2 are respectively provided with inlet and outlet. The area above the base 1 between the inlet and outlet is the outlet area. The annular turntable 3 is rotatably mounted on the base 1 and connected to the drive mechanism 9. Under the drive of the drive mechanism 9, the surface of the annular turntable 3 passes through the oil draining zone, the pre-cooling zone, the quick-freezing zone and the discharge zone in sequence. Multiple partitions 4 are provided, and the multiple partitions 4 are arranged in a ring array on the ring turntable 3; Multiple core rods 5 are arranged side by side on the partition plate 4; The alternating motion mechanism 6 is connected to the core rod 5, driving the adjacent core rod 5 to move up and down alternately.

[0018] The alternating motion mechanism 6 includes a motion slider 62, a transmission gear 63, a driving gear 65, a driven gear 66, a connecting rod 64, a first transmission shaft 67, a second transmission shaft 610, a first bevel gear 68, a second bevel gear 69, and a planetary gear 611. Multiple vertical grooves 61 are equally spaced on one side surface of the partition 4; The motion slider 62 is slidably mounted on the vertical slide groove 61, and a transmission gear 63 is provided between adjacent motion sliders 62, and the side wall of the motion slider 62 is provided with a tooth groove corresponding to the transmission gear 63. Both the driving gear 65 and the driven gear 66 are rotatably mounted on the surface of the partition plate 4, and the driving gear 65 meshes with the driven gear 66; One end of the connecting rod 64 is rotatably connected to the eccentric part of the surface of the driven gear 66, and the other end of the connecting rod 64 is rotatably connected to the surface of one of the moving sliders 62. One end of the first drive shaft 67 is connected to the drive gear 65, and the other end of the first drive shaft 67 is connected to the first bevel gear 68. The second bevel gear 69 meshes with the first bevel gear 68, and the bottom of the second bevel gear 69 is connected to the second drive shaft 610. The bottom end of the second drive shaft 610 is fitted with an annular turntable 3 and connected to a planetary gear 611; The base 1 has an annular movable channel corresponding to the second drive shaft 610. The base 1 is also fixedly equipped with a sun gear 612 and a planetary gear 611 is arranged around the sun gear 612 and meshes with the sun gear 612. In use, the fried bamboo wheels are strung onto the mandrel 5. As the annular turntable 3 rotates, the bamboo wheels on the mandrel 5 sequentially enter the oil-draining zone, pre-cooling zone, and quick-freezing zone. During the rotation of the annular turntable 3, the planetary gears simultaneously rotate around the sun gear 612. Under the action of the second transmission shaft 610, the second bevel gear 69 rotates. The second bevel gear 69 sequentially drives the first bevel gear 68, the first transmission shaft 67, and the driving gear 65 to rotate. The driving gear 65 drives the driven gear 66 to rotate. The driving gear 65, through the connecting rod 64, drives the moving slider 62 in the vertical slide groove 61 to continuously move up and down. Under the action of the transmission gear 63, adjacent moving sliders 62 move in opposite directions, causing adjacent mandrels 5 to alternately move up and down. The alternating up and down movement of the mandrels 5 causes the bamboo wheels on the mandrel 5 to produce directional and regular mechanical vibrations. This vibration effectively shakes off or throws out the oil droplets adhering to the surface and cavities of the bamboo wheels, with an efficiency far higher than simply relying on gravity for static oil draining. The bamboo wheel entering the oil-draining zone achieves efficient oil draining. When the bamboo wheel enters the pre-cooling zone with the annular turntable 3, the alternating motion mechanism 6 breaks the insulating air film formed on the surface of the bamboo wheel, allowing cold air to always directly contact the product surface, maximizing heat exchange efficiency. Furthermore, the area where the bamboo wheel contacts the core rod 5 is a dead corner in pre-cooling. Vibration causes the contact point of the core rod 5 to change continuously, ensuring that the entire surface of the bamboo wheel can be evenly contacted with cold air, avoiding problems such as excessively high local temperatures and uneven pre-cooling. The hollow interior of the bamboo wheel easily accumulates heat and moisture, which is a difficult point in pre-cooling. Up and down vibration will create a chimney effect inside the bamboo wheel. When the bamboo wheel is lifted, the hot air inside is drawn upwards, and when the bamboo wheel is lowered, the cold air outside is drawn in. This forced air exchange can efficiently remove the heat and moisture deep inside the bamboo wheel, thereby achieving synchronous and rapid cooling from the inside out. After the bamboo wheel is quick-frozen in the quick-freezing zone with the annular turntable 3, it comes out from the discharge port of the freezing tunnel 2 and is harvested manually.

[0019] It should be noted that: The alternating motion mechanism 6 gives the bamboo wheel a very high upward or downward acceleration. The oil droplets inside the bamboo wheel generate an inertial force opposite to the direction of acceleration due to inertia. When the inertial force is greater than the adhesion of the grease, the oil droplets separate from the inner wall. The thrown oil droplets are suspended in the hollow area inside the bamboo wheel. The repeated shaking makes this process repeat continuously, and more and more oil droplets are thrown away. They gather together and grow larger during the shaking, and finally drip from the opening of the bamboo wheel under the action of gravity, thereby realizing the oil drainage of the inner cavity of the main wheel.

[0020] In this embodiment, the part of the sun gear 612 corresponding to the quick-freezing zone and the discharge zone is designed without teeth. This prevents the alternating motion mechanism 6 from generating alternating motion when it enters the quick-freezing zone and the discharge zone, which is beneficial for quick-freezing and manual harvesting.

[0021] In this embodiment, the diameter of the driving gear 65 is 2-5 times that of the driven gear 66. With the cooperation of the driving gear 65 and the driven gear 66, the rotation speed can be increased, the frequency of the mandrel 5 moving up and down alternately can be increased, and thus the oil draining and pre-cooling effects can be improved.

[0022] In this embodiment, the drive mechanism 9 includes a drive motor 91 and a drive gear 92. The drive motor 91 is connected to the drive gear 92. The outer wall of the annular turntable 3 is provided with drive tooth grooves corresponding to the drive gear 92. In use, the drive motor 91 drives the drive gear 92 to rotate, and the drive gear 92 drives the annular turntable 3 to rotate.

[0023] In this embodiment, a cold air cooler 7 is installed in the pre-cooling zone of the freezing tunnel 2, and a liquid nitrogen quick-freezing machine 8 is installed in the quick-freezing zone of the freezing tunnel 2.

[0024] refer to Figure 8 The second embodiment of the present invention: Based on the above embodiment 1, the core rod 5 includes a core rod body 51, a necked rod 53, a blocking plate 52, a rod head 54, and a movable sleeve 55; One end of the core rod 51 is connected to the rod head 54 via the necking rod 53, and the other end of the core rod 51 is provided with a baffle plate 52. The rod head 54 has a hemispherical structure, and the movable sleeve 55 has a disc-shaped structure and is sleeved on the necking rod 53. The surface of the motion slider 62 is provided with a insertion groove 56 corresponding to the core rod 5. A limit groove is provided on the inner wall of the insertion groove 56. A limit block 57 is provided in the limit groove. The side of the limit block 57 facing the insertion groove 56 is set with an incline. A limit plate 58 is provided at the tail of the limit block 57. The inside of the motion slider 62 is provided with a moving groove corresponding to the limit plate 58. A limit spring 59 is installed in the moving groove. One end of the limit spring 59 is connected to the motion slider 62, and the other end of the limit spring 59 is connected to the limit plate 58. In use, insert the head 54 of the mandrel 5 directly into the insertion slot 56. After the head 54 pushes open the limiting block 57, the limiting block 57 moves to the rear of the head 54, preventing the mandrel 5 from disengaging from the insertion slot 56, thus enabling the quick installation of the mandrel 5. When it is necessary to remove the mandrel 5, press the mandrel 5 further into the insertion slot 56, causing the limiting block 57 to move to the rear of the movable sleeve 55. Then, directly remove the mandrel 5 outward, causing the movable sleeve 55 to move forward. The limiting block 57 moves along the surface of the movable sleeve 55 to the head 54, thereby enabling the mandrel 5 to disengage. This embodiment enables quick assembly and disassembly of the core rod 5, which is beneficial for loading and unloading bamboo wheels.

[0025] In this embodiment, multiple oil receiving grooves are formed on the surface of the annular turntable 3, and the oil receiving grooves are located directly below the mandrel 5.

[0026] In this embodiment, the freezing tunnel 2 is equipped with baffles at the boundaries of the oil draining zone, the pre-cooling zone and the quick-freezing zone. The baffles have entry and exit windows corresponding to the partitions 4. With the cooperation of the baffles and the partitions 4, the isolation of each zone is achieved.

[0027] The working principle of this invention is as follows: The fried bamboo wheels are strung onto the core rod 5. As the annular turntable 3 rotates, the bamboo wheels on the core rod 5 sequentially enter the oil draining zone, pre-cooling zone, and quick-freezing zone. During the rotation of the annular turntable 3, planetary gears simultaneously rotate around the sun gear 612. Under the action of the second transmission shaft 610, the second bevel gear 69 rotates. The second bevel gear 69 sequentially drives the first bevel gear 68, the first transmission shaft 67, and the driving gear 65 to rotate. The driving gear 65 drives the driven gear 66 to rotate. The driving gear 65, through the connecting rod 64, drives the moving slider 62 in the vertical slide groove 61 to continuously move up and down. Under the action of the transmission gear 63, adjacent moving sliders 62 move in opposite directions, causing adjacent core rods 5 to alternately move up and down. This vibration effectively shakes off or throws out oil droplets adhering to the surface and cavities of the bamboo wheels. As the bamboo wheels enter the pre-cooling zone with the annular turntable 3, they alternately move... Mechanism 6 can break the insulating air film formed on the surface of the bamboo wheel, allowing cold air to always directly contact the product surface, maximizing heat exchange efficiency. Furthermore, the area where the bamboo wheel contacts the core rod 5 is a dead zone for pre-cooling. Vibration causes the contact point of the core rod 5 to change continuously, ensuring that the entire surface of the bamboo wheel can be evenly contacted by cold air, avoiding problems such as excessively high local temperatures and uneven pre-cooling. The hollow interior of the bamboo wheel easily accumulates heat and moisture, which is a difficult point for pre-cooling. Up and down vibration will create a chimney effect inside the bamboo wheel. When the bamboo wheel is lifted, the hot air inside is drawn upwards, and when the bamboo wheel is lowered, the cold air outside is drawn in. This forced air exchange can efficiently remove the heat and moisture deep inside the bamboo wheel, thereby achieving synchronous and rapid cooling from the inside out. After the bamboo wheel is quick-frozen in the quick-freezing zone along with the annular turntable 3, it comes out from the discharge port of the freezing tunnel 2 and is harvested manually.
