Description

Technical Field

[0001] This invention relates to the field of quick-freezing technology, and in particular to an ultra-low temperature quick-freezing machine and method for cold chain preservation of abalone. Background Technology

[0002] Abalone quick-freezing machines are rapid refrigeration devices that use ultra-low temperature (usually below -35℃) and strong convection circulation technology. They can bring the core temperature of abalone through the maximum ice crystal formation zone (-1℃ to -5℃) in a very short time, thereby preventing large ice crystals from forming inside the cells and piercing the tissue. This maximizes the preservation of the abalone's tender texture, nutrients, and cell integrity. After thawing, the abalone can still maintain its elasticity and flavor close to that of fresh abalone. During the low-temperature quick-freezing of abalone, it is necessary to perform operations such as "coating with ice".

[0003] Commonly available spray-type ice-coating quick-freezing machines typically only coat one side of the abalone with ice. However, this method cannot coat abalone completely and repeatedly. Therefore, in actual use, abalone may experience "freezing burn" or other problems during subsequent cold air drying or quick-freezing due to the thin ice coating. Furthermore, a thin single layer of ice coating can easily lead to ice crystal recrystallization during repeated freeze-thaw cycles or temperature changes, damaging the abalone's muscle tissue. Summary of the Invention

[0010] As a preferred embodiment of the abalone ultra-low temperature quick-freezing machine for cold chain preservation of the present invention, the shaking component further includes a storage seat, a mounting seat is provided on one side of the storage seat, and a guide pipe extending into the interior of the storage seat is provided on one side of the mounting seat.

[0011] As a preferred embodiment of the abalone ultra-low temperature quick-freezing machine for cold chain preservation of the present invention, the feeding component further includes a push rod, a baffle is provided on the outer wall of the push rod, and a return spring is provided on one side of the baffle.

[0012] As a preferred embodiment of the abalone ultra-low temperature quick-freezing machine for cold chain preservation of the present invention, wherein: a curved rod is movably installed at one end of the push rod, a support plate is provided at one end of the curved rod, an arc-shaped plate is slidably connected to the inside of the storage seat at the top of the support plate, and the placement seat is movably installed inside the arc-shaped plate.

[0013] As a preferred embodiment of the abalone ultra-low temperature quick-freezing machine for cold chain preservation of the present invention, a conveying base plate is provided between the transmission components, and a spray seat is provided directly above the conveying base plate.

[0014] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a quick-freezing method for abalone using an ultra-low temperature quick-freezing machine for cold chain preservation, comprising an ultra-low temperature quick-freezing machine for abalone for cold chain preservation, and including the following steps: S1: Initial feeding and quantitative preparation Abalone is stored in the storage seat of the shaking component, the pusher is in the initial position, the placement seat is located at the bottom of the storage seat, the placement groove receives shell-less abalone, the arc plate is at the bottom of the storage seat, and no material passes through the guide pipe; S2: Quantitative delivery and vibration separation The dual-axis motor starts, which drives the push rod to move laterally through the rotating rod, rotating plate and connecting rod, and the push rod pushes the push plate to move. The push plate contacts and drives the push rod to move. The push rod compresses the return spring and drives the crank rod to move. The crank rod raises the arc plate through the support plate. The placement seat rises along the guide of the auxiliary groove and swings left and right using the wave-shaped trajectory of its top, causing the abalone piled up in the placement groove to shake and fall, thus realizing the input of a single abalone. Abalone fall into the conveyor base plate through the feed pipe, completing a single quantitative feeding. S3: Push and Flip Trigger The pusher plate moves laterally under the pusher plate's drive, while the moving rod moves along the guide groove trajectory, so that the pusher plate pushes the abalone into the tilting seat of the flipping part, and the lifting seat can slide up and down in the lifting groove. The weight of the abalone causes the tilting seat to rotate, which in turn drives the auxiliary plate and the transmission rod to rotate synchronously. The spiral groove on the outer wall of the guide rod slides into the connecting seat, and the connecting seat compresses the spring. Under the combined action of gravity and spring force, the tilting seat automatically rotates 180°, thus turning the abalone over.

[0015] S4: Multi-layered double-sided ice coating After being flipped over, the abalone slides out through the guide seat and enters the next process, passing through the spray seat again for the ice coating operation; Through the continuous action of multi-level components, the abalone completes multiple pushes, flips, and sprays in sequence to achieve a multi-layered, double-sided ice coating. Magnets attract the auxiliary plate and the assembly plate, allowing the tilting seat to maintain a stable angle after flipping, facilitating continuous operation; The device continuously cycles through steps S2 to S4 until all abalone have undergone multi-layer double-sided ice coating treatment, preventing subsequent freezing and burning and improving the quality of refrigeration or transportation.

[0016] The beneficial effects of this invention are as follows: By setting up a multi-stage component, which utilizes the cooperation of transmission and pushing components, the user can effectively push abalone. Simultaneously, through the use of a flipping component, when shell-less abalone falls into the tilting seat, pressure is applied to the spring via the cooperation of the transmission rod and connecting seat, thereby flipping the abalone. This design allows the user to flip the abalone multiple times when applying ice coating, achieving multi-layer double-sided ice coating, which not only prevents freezing and burning during subsequent processing but also improves the quality of the abalone during refrigeration or transportation. Furthermore, through a quantitative component, which utilizes the cooperation of a shaking component and a feeding component, the abalone can be shaken by the sliding connection of the auxiliary groove when the placement seat is raised, achieving single-pass delivery and avoiding the accumulation of abalone during subsequent ice coating, which would affect the operation.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides an ultra-low temperature quick-freezing machine and quick-freezing method for abalone in cold chain preservation, which can achieve the effect of multi-layer flipping. It includes a main body 1, which is the body of the freezer, and a shell 2 which is part of the main body 1. The shell 2 is disposed on one side of the main body 1. The shell 2 has a hollow structure and provides an installation position for the multi-level components 3 and the quantitative components 4. The multi-level components 3 and the quantitative components 4 are disposed inside the shell 2. The multi-stage component 3 includes a transmission component 31, a pusher component 32 disposed on one side of the transmission component 31, and a flipping component 33 disposed on one side of the pusher component 32. The transmission component 31 is disposed inside the housing 2 and is connected to the pusher component 32. The flipping component 33 is disposed between the pusher components 32. The flipping component 33 includes an assembly plate 332 and a guide seat 329, an auxiliary plate 333 disposed on one side of the assembly plate 332, a magnet 334 disposed on one side of the auxiliary plate 333 and the assembly plate 332, a tilting seat 335 disposed on one side of the auxiliary plate 333, a transmission rod 336 disposed on one side of the assembly plate 332, a connecting seat 337 disposed outside the transmission rod 336, a spring 338 disposed on one side of the connecting seat 337, and an adjusting rod 339 disposed at one end of the spring 338. The guide seat 329 has an inclined guide groove inside. The material can be guided after being flipped, allowing for effective discharge. Assembly plate 332 is bolted to the inside of housing 2. Auxiliary plate 333 is connected to assembly plate 332 via bearings. Magnet 334 is located in a groove on the adjacent side of assembly plate 332 and auxiliary plate 333, providing a mounting position for tilting seat 335. Several horizontally distributed dividing plates are bolted inside tilting seat 335 to divide the material. The acute-angled sides of tilting seat 335 effectively prevent material from falling directly from its surface due to inertia. Conduction rod 336 is mounted on one outer wall of assembly plate 332 via bearings and is connected to auxiliary plate 333 via bearings. The outer wall of conversion rod 336 has two interlocking spiral grooves. When conversion rod 336 rotates, connecting seat 337 follows. When one of the spiral grooves rotates to its furthest point and continues to rotate, it will enter the interior of another spiral groove through its staggered state. The transmission rod 336 is connected to the connecting seat 337 through the spiral groove on its outer wall. One end of the spring 338 is fixed to the outer wall of one side of the connecting seat 337, while the other end is connected to the adjusting rod 339. The adjusting rod 339 includes a screw and a threaded sleeve. Therefore, the user can adjust the pressure of the spring 338 by rotating the screw included in the adjusting rod 339. The quantitative component 4 includes a shaking element 41, the shaking element 41 being disposed on one side of the pusher 32, and a feeding element 42 being disposed on one side of the shaking element 41. The shaking element 41 is disposed on one side of the pusher 32, and the feeding element 42 can feed materials to avoid material accumulation. The shaking member 41 includes an auxiliary groove 414, and the pushing member 32 includes a placement seat 427. The top of the placement seat 427 is provided with a placement groove 428. The auxiliary groove 414 is provided on both inner walls of the storage seat 411 included in the shaking member 41, and the top groove of the auxiliary groove 414 is wavy. The placement seat 427 is slidably connected to the auxiliary groove 414 through the guide rods on both sides. Therefore, when the placement seat 427 is raised, the sliding connection with the auxiliary groove 414 can be used to make the placement seat 427 shake, so as to avoid the situation that there is too much material inside the placement groove 428. The auxiliary plate 333 is connected to the transmission rod 336 in a transmission manner, and the assembly plate 332 is connected to the transmission rod 336 in a movable manner. The rotation of the tilting seat 335 drives the auxiliary plate 333 to rotate and the transmission rod 336 to rotate. The transmission rod 336 uses the sliding connection between the connecting seat 337 and the spiral groove on the outer wall of the transmission rod 336 to compress the spring 338, so that the tilting seat 335 can perform the action of turning the material when subjected to gravity.

[0031] Specifically, the flipping component 33 also includes a mounting tube 331, which is movably mounted on one side of the outer wall of the assembly plate 332. The transmission rod 336 is located inside the mounting tube 331. The mounting tube 331 is also movably mounted on the outer wall of the assembly plate 332 via a bearing, and the transmission rod 336 is located at the axis of the mounting tube 331. One end of the mounting tube 331 extends to the outside of the housing 2.

[0032] In use, firstly, cold air is injected into the interior of the shell 2. When the abalone falls onto the surface of the tilting seat 335, the tilting seat 335 will use gravity to cause the auxiliary plate 333 to rotate. After the auxiliary plate 333 rotates, it will drive the transmission rod 336 to rotate, which in turn drives the spiral groove on its outer wall to rotate. During the entire rotation of the transmission rod 336, the spiral groove can use its sliding connection with the connecting seat 337 to allow the connecting seat 337 to move laterally. During the lateral movement of the connecting seat 337, the connecting seat 337 will compress the spring 338. Since the other end of the spring 338 is connected to the adjusting rod 339... The connection is such that it does not affect the normal force on the spring 338. Therefore, under the action of gravity and inertia, the abalone drives the tilting seat 335 to rotate to a certain angle. The tilting seat 335 will automatically rotate 180 degrees by utilizing the spiral groove on the outer wall of the transmission rod 336, the connecting seat 337 and the spring 338. During the 180-degree rotation, the material will be flipped over and fall off. The flipped abalone will be guided by the guide seat 329. After the tilting seat 335 rotates 180 degrees, the mutual magnetic attraction between the magnets 334 can be used to keep the tilting seat 335 at a certain angle.

[0033] In summary, the tilting seat 335, through the cooperation of the transmission rod 336, the connecting seat 337, and the spring 338, can effectively flip the abalone under gravity. Furthermore, the mutual attraction between the magnets 334 allows the flipped tilting seat 335 to rotate 180 degrees, ensuring reliable flipping of the shell-less abalone. The use of multiple flipping components 33 allows the shell-less abalone to be effectively coated with ice multiple times during each ice coating and transport process. This design not only allows for multiple ice coatings on both sides of the abalone, effectively preventing freezing and burning during subsequent processing, but also further enhances the protection and quality assurance of the abalone during transportation.

[0034] Example 2, refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This is the second embodiment of the present invention. Unlike the previous embodiment, it solves the problem of pushing abalone.

[0035] Specifically, the transmission component 31 includes a dual-axis motor 315 installed inside the housing 2. The output end of the dual-axis motor 315 is provided with a rotating rod 311. One end of the rotating rod 311 is provided with a rotating plate 312. One end of the rotating plate 312 is movably mounted with a connecting rod 313. One end of the connecting rod 313 is movably mounted with a push rod 314. The dual-axis motor 315 is bolted to one side inside the housing 2. The output end of the dual-axis motor 315 is connected to the rotating rod 311 through a coupling. The rotating rod 311 is connected to the rotating plate 312 through bolts. Therefore, when the rotating rod 311 rotates, the rotating rod 311 can drive the rotating plate 312 to rotate synchronously. The rotating plate 312 is movably connected to the connecting rod 313 through a rotating shaft. The connecting rod 313 is movably connected to the push rod 314 through the rotating shaft. The push rod 314 can only move laterally left and right.

[0036] Furthermore, the pusher 32 includes a side plate 327, a guide groove 328 is provided on the outer wall of the side plate 327, and a push plate 321 with a horizontal structure is provided on one side of the side plate 327. A synchronizing rod 322 is provided between the push plates 321. The push plates 321 are slidably connected to the outer walls of both sides of the side plate 327 and are located inside the housing 2. The push plates 321 and the push rod 314 are fixedly connected by bolts. The side plate 327 is fixed inside the housing 2 by bolts and is slidably connected to the push plates 321.

[0037] The push plate 321 has a lifting groove 323 on the side near the side plate 327. A lifting seat 324 is slidably connected inside the lifting groove 323. A moving rod 325 is provided on one side of the lifting seat 324, which extends into the guide groove 328. A push plate 326 is provided at the bottom of the moving rod 325. The lifting groove 323 is a longitudinal transverse groove, and the lifting groove 323 and the lifting seat 324 are slidably connected. The moving rod 325 is bolted to one side of the outer wall of the lifting seat 324. The moving rod 325 extends into the guide groove 328. Therefore, when the push plate 321 moves laterally, the push plate 321 can use the action of the lifting groove 323 and the guide groove 328 to make the lifting seat 324 rise and fall inside the lifting groove 323.

[0038] In use, the dual-axis motor 315 is first started. The dual-axis motor 315 is connected to the rotating rod 311, which rotates the rotating rod 311. The rotating rod 311 is connected to the rotating plate 312, which drives the connecting rod 313 to move. The connecting rod 313 is connected to the push rod 314, which drives the push rod 314 to move laterally. The push rod 314 drives the push plate 321 to move. The push plate 321 drives the lifting seat 324 to move. The lifting seat 324 drives the moving rod 325 to move. The moving rod 325 drives the push plate 326 to move. The moving rod 325 uses the guide groove 328 to synchronously drive the lifting seat 324 to move inside the lifting groove 323 during the movement.

[0039] In summary, the pusher plate 326, through its interaction with the moving rod 325 and the lifting seat 324, allows the lifting seat 324 to reciprocate up and down inside the lifting groove 323. At the same time, the lateral movement of the pusher plate 326 enables the user to effectively push the material. This design not only reliably pushes the abalone but also scrapes off residual water stains on the conveyor base plate 5, effectively preventing the problem of icing due to prolonged neglect of cleaning.

[0040] Example 3, referring to Figure 3 and Figure 4 This is the third embodiment of the present invention. Unlike the previous embodiment, it solves the problem of feeding abalone separately.

[0041] Specifically, the shaking component 41 also includes a storage seat 411. A mounting seat 412 is provided on one side of the storage seat 411, and a guide pipe 413 extending into the storage seat 411 is provided on one side of the mounting seat 412. The storage seat 411 is installed inside the shell 2 by bolts, and the storage seat 411 can store materials. The guide pipe 413 can transport shellless abalone, provide a position for the transport of abalone, and can also separate the abalone.

[0042] Furthermore, the feed component 42 also includes a push rod 421. A baffle 422 is provided on the outer wall of the push rod 421. A return spring 423 is provided on one side of the baffle 422. The push rod 421 is slidably connected to the inside of the housing 2. The baffle 422 is installed on the outer wall of the push rod 421 by bolts. The return spring 423 is sleeved on the outer wall of the push rod 421 and is located inside the rod groove inside the housing 2.

[0043] The push rod 421 has a crank rod 424 movably mounted on one end, and a support plate 425 is provided on one end of the crank rod 424. The top of the support plate 425 is provided with an arc-shaped plate 426 that is slidably connected to the inside of the storage seat 411. The placement seat 427 is movably mounted inside the arc-shaped plate 426. The push rod 421 and the crank rod 424 are movably connected through a rotating shaft. The crank rod 424 is connected to the assembly plate 332 by bolts. The arc-shaped plate 426 is connected to the assembly plate 332 by bolts. The arc-shaped plate 426 is slidably connected to the inside of the storage seat 411.

[0044] Preferably, a conveying base plate 5 is provided between the transmission components 31, and a spray seat 6 is provided directly above the conveying base plate 5. The conveying base plate 5 can separate the abalone after feeding, and the surface of the conveying base plate 5 is provided with several drainage holes, which can play the role of conveying water flow. The spray seat 6 includes a nozzle, a spray seat and a liquid guiding tank.

[0045] The rest of the structure is the same as in Example 2.

[0046] In use, when the push plate 321 in the pusher 32 moves laterally continuously, the push plate 321 can contact and drive the push rod 421 to move. The push rod 421 then presses the baffle 422, and the baffle 422 further presses the return spring 423. During the movement of the push rod 421, the push rod 421 can utilize its cooperation with the crank rod 424, so that the crank rod 424 can drive the support plate 425 to move by means of its cooperation with the support plate 425. The support plate 425 further drives the arc plate 426 to move. The arc plate 426 will move inside the storage seat 411 and can drive the placement seat 427 on its top to move. Due to the guide rods on both sides of the placement seat 427 and the auxiliary groove 41 4. The connection is slidable, so when the arc plate 426 is raised, the abalone will accumulate inside the placement trough 428. When the arc plate 426 continues to rise, because the groove at the top of the auxiliary trough 414 is wavy, and the placement seat 427 is slidably connected to the auxiliary trough 414 through the guide rods on both sides, the placement seat 427 will swing left and right after it is raised, thereby shaking off the large amount of material accumulated inside the placement trough 428, so that only one shellless abalone is left inside the placement trough 428. When the placement seat 427 is raised to the top, because the movement trajectory of the arc plate 426 and the auxiliary trough 414 is circular, the abalone inside the placement trough 428 will pass through the guide pipe 413 due to gravity and finally fall into the interior of the conveying base plate 5.

[0047] In summary, by using the quantitative component 4, the interaction between the shaking component 41 and the feeding component 42 allows the placement seat 427 inside to interact with the auxiliary tank 414, thereby effectively shaking a large amount of material and avoiding the accumulation of abalone. This prevents the abalone without shells from sticking together during the subsequent ice coating process, thus avoiding affecting the subsequent processing of the abalone.

[0048] Example 4, refer to Figures 1 to 8 This is the fourth embodiment of the present invention, which provides a quick-freezing method for abalone using an ultra-low temperature quick-freezing machine for cold chain preservation, comprising the following steps: S1: Initial feeding and quantitative preparation Abalone is stored in storage seat 411 of shaking member 41, pusher 32 is in initial position, placement seat 427 is located at the bottom of storage seat 411, placement groove 428 receives shell-less abalone, arc plate 426 is located at the bottom of storage seat 411, and no material passes through guide tube 413. S2: Quantitative delivery and vibration separation When the dual-axis motor 315 starts, it drives the push rod 314 to move laterally via the rotating rod 311, rotating plate 312 and connecting rod 313. The push rod 314 pushes the push plate 321 to move. The push plate 321 contacts and drives the push rod 421 to move. The push rod 421 compresses the return spring 423 and drives the crank rod 424 to move. The crank rod 424 raises the arc plate 426 through the support plate 425. The placement seat 427 rises along the guide of the auxiliary groove 414 and swings left and right using the wave-shaped trajectory of its top, causing the abalone piled in the placement groove 428 to shake and fall, thus realizing the input of a single abalone. Abalone falls into conveyor base plate 5 through guide pipe 413, completing a single quantitative feeding; S3: Push and Flip Trigger The pusher plate 326 moves laterally under the drive of the pusher plate 321, while the moving rod 325 moves along the trajectory of the guide groove 328, so that the pusher plate 326 pushes the abalone into the tilting seat 335 of the flipping part 33, while the lifting seat 324 can slide up and down in the lifting groove 323. The weight of the abalone causes the tilting seat 335 to rotate, which in turn drives the auxiliary plate 333 and the transmission rod 336 to rotate synchronously. The spiral groove on the outer wall of the transmission rod 336 slides in conjunction with the connecting seat 337. The connecting seat 337 compresses the spring 338. Under the combined action of gravity and spring force, the tilting seat 335 automatically rotates 180° to flip the abalone.

[0049] S4: Multi-layered double-sided ice coating After being flipped over, the abalone slides out through the guide seat 329 and enters the next process, and then passes through the spray seat 6 to be coated with ice again; Through the continuous action of the multi-level component 3, the abalone completes multiple pushes, flips and sprays in sequence to achieve a multi-layered double-sided ice coating; Magnet 334 attracts auxiliary plate 333 and assembly plate 332, so that tilting seat 335 maintains a stable angle after flipping, which facilitates continuous operation; The device continuously cycles through steps S2 to S4 until all abalone have undergone multi-layer double-sided ice coating treatment, preventing subsequent freezing and burning and improving the quality of refrigeration or transportation.
