A freezing device for processing soft-boiled abalone and its use method

Abstract

The present invention discloses a freezing device for a processing technology of soft-boiled abalone and a method for using the same, and belongs to the technical field of abalone freezing processing. It includes a gasification liquid nitrogen freezer, an electric valve sleeve, an electric adsorption module, a first electric telescopic rod, and a fan-shaped storage tank. By adopting a gasification liquid nitrogen freezer in combination with a non-direct contact freezing method, the traditional liquid nitrogen quick-freezing method easily causes the surface of the abalone to freeze rapidly while the internal temperature drops slowly, resulting in a large temperature difference between the inside and outside, which destroys the cell structure. In contrast, the use of low-temperature gas to indirectly cool the abalone avoids the problem of too fast freezing of the surface and ensures that the temperature changes of the entire abalone during the freezing process are more consistent. In addition, by injecting an antifreeze agent or a protective agent into the abalone, the formation of large ice crystals can be effectively reduced to maintain its internal delicate structure. This not only enhances the elasticity and taste after thawing, but also greatly reduces the risk of texture damage caused by uneven freezing.

Description

Technical Field

[0001] The invention relates to the technical field of abalone freezing processing, and more specifically to freezing equipment for a soft-boiled abalone processing technology and a use method thereof. Background Art

[0002] In the field of modern soft-boiled abalone processing, existing technologies generally use liquid nitrogen quick freezers for freezing. Liquid nitrogen quick freezers can quickly freeze food in a short period of time by providing extremely low temperatures (about -196°C). However, when applied to soft-boiled abalone, a product that has strict requirements on internal structure and taste, its direct contact freezing method may cause the surface of the abalone to freeze quickly, while the internal temperature drops slowly, resulting in a large temperature difference between the inside and outside, destroying the cell structure and affecting the texture of the abalone.

[0003] In order to overcome these problems and better maintain the freshness and flavor of abalone, modern processing technology has begun to introduce freezing equipment as an auxiliary means. By using freezing equipment, the temperature of abalone can be quickly reduced in the pre-freezing stage to prevent the formation of large ice crystals and thus avoid destroying the cell structure. The application of these technologies can not only significantly improve production efficiency, but also ensure that the quality and taste of each batch of products are more consistent. In addition, in the existing production line, indirect cooling is also used to freeze the soft-boiled abalone to avoid direct contact between the low-temperature gas and the abalone.

[0004] However, in the process of freezing soft-boiled abalone using indirect cooling, since the indirect cooling method relies on cooling medium to transfer cold, the actual production process may result in a large temperature gradient between the surface and the inside of the abalone, causing the outside to freeze while the inside has not yet reached the required temperature, resulting in inconsistent cooling speed. This uneven freezing process will cause the speed and size of ice crystals to form in different areas to be inconsistent. The formation of large ice crystals on the outside will destroy the cell structure and affect the texture of the abalone, making it dry, rough or losing its original elasticity.

[0020] S2: Then, the servo motor drives the double-sided gear ring and drives the auxiliary reagent injection mechanism through the linkage gear module; the injection mechanism moves along the sliding slot to the abalone and inserts into its body. The piston push rod pushes the injection cylinder to extract the antifreeze or protective agent from the fan-shaped storage tank and inject it into the abalone;

The second electric telescopic rod retracts the electric adsorption module to make it enter the electric valve sleeve; the gasification liquid nitrogen freezer is started, and the low-temperature gas indirectly cools the abalone through the electric valve sleeve to ensure uniform freezing;

[0022] S4: Finally, turn on the vibration module to vibrate the abalone at high frequency to promote uniform distribution of the auxiliary reagents; then continue to use the vaporized liquid nitrogen freezer for final freezing until the desired state is reached to ensure that the abalone is uniformly frozen inside and out.

[0023] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0024] By using a gasified liquid nitrogen freezer combined with a non-direct contact freezing method, the uniformity of abalone during the freezing process is improved. The traditional liquid nitrogen quick-freezing method easily causes the surface of the abalone to freeze quickly while the internal temperature drops slowly, resulting in a large temperature difference between the inside and outside, which damages the cell structure. In contrast, the use of low-temperature gas to indirectly cool the abalone avoids the problem of too rapid freezing of the surface and ensures that the temperature changes of the entire abalone during the freezing process are more consistent. In addition, by injecting antifreeze or protective agents into the abalone, the formation of large ice crystals can be effectively reduced to maintain its delicate internal structure. This not only enhances the elasticity and taste after thawing, but also greatly reduces the risk of texture damage caused by uneven freezing.

[0025] The operating efficiency and convenience of the production line are improved through the electric adsorption module, multi-axis robotic arm and linkage gear module. The electric adsorption module can automatically adsorb and fix the abalone, and cooperate with the action of the first electric telescopic rod to achieve precise positioning and flat pressing of the abalone, providing ideal conditions for subsequent injection of auxiliary reagents. At the same time, the linkage gear module drives the precise movement of the injection mechanism to ensure that each injection can accurately inject the required dose of antifreeze into the abalone. It not only reduces the need for manual intervention, but also shortens the time of each processing step, thereby significantly improving the overall production efficiency.

[0026] By introducing a vibration module, the abalone is vibrated at high frequency after the auxiliary reagent is injected to promote the uniform distribution and full mixing of the reagent in the tissue, ensuring that each abalone can obtain the best protection effect. In addition, by using a fan-shaped storage tank with a transparent capacity plate structure, the operator can monitor the remaining amount of reagent in real time and replenish it in time to ensure the continuity and stability of production. This design not only helps to maintain the high quality standards of the product, but also effectively prevents product quality fluctuations caused by insufficient or uneven distribution of reagents, and ultimately achieves a high degree of consistency in the quality and taste of each batch of products.

[0045] The following is a detailed description of a refrigeration device for abalone processing technology provided by the present invention and a method for using the same in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for describing the embodiments in more detail, and are not intended to specifically limit the present invention.

[0046] like Figures 1 to 9As shown, an embodiment of the present invention provides a refrigeration equipment for abalone processing technology, including a gasification type liquid nitrogen freezer 1, the refrigeration end of the gasification type liquid nitrogen freezer 1 is circular, and an electric valve sleeve 2 is fixedly installed inside the circle, and an electric adsorption module 15 for fixing the soft-hearted abalone is arranged at the center position of the sleeve inner circle of the electric valve sleeve 2, and a lifting bracket 3 is fixedly connected to the outside of the gasification type liquid nitrogen freezer 1, and a first electric telescopic rod 4 is fixedly installed on the top of the lifting bracket 3, and the output end of the first electric telescopic rod 4 is aligned with the center of the circle of the electric valve sleeve 2, and a disc bracket 5 is fixedly installed on the output end of the first electric telescopic rod 4, and the upper surface of the disc bracket 5 is circumferentially fixed with four fan-shaped storage tanks 11 for storing freezing auxiliary reagents;

[0047] The bottom of the disc support 5 is also provided with a circular partition 7, and an auxiliary reagent injection mechanism 8 is provided on the circular partition 7 at the position directly at the bottom of each sector-shaped storage tank 11, and a driving mechanism 9 for driving each auxiliary reagent injection mechanism 8 is also installed at the bottom of one of the sector-shaped storage tanks 11 on the disc support 5;

[0048] Among them, the driving mechanism 9 includes a servo motor 91 and a linkage gear module 96 that is fitted with each auxiliary reagent injection mechanism 8. The linkage gear module 96 is driven to rotate by the driving action of the output end of the servo motor 91, so that each auxiliary reagent injection mechanism 8 can inject the auxiliary reagent into the soft-boiled abalone in a circumferential manner when the soft-boiled abalone is frozen so that the frozen surface of the soft-boiled abalone is evenly frozen.

[0049] In order to solve the problem that the freezing speed of abalone inside and outside is inconsistent in the existing freezing process, resulting in damage to the texture of abalone, the above-mentioned technical scheme is now adopted to solve the problem. The above-mentioned technical scheme is mainly composed of a gasification liquid nitrogen freezer 1, an electric valve sleeve 2, a lifting bracket 3, a first electric telescopic rod 4, a disc bracket 5, a ring partition 7, an auxiliary reagent injection mechanism 8, and a driving mechanism 9. The configured gasification liquid nitrogen freezer 1, the electric valve sleeve 2, and the first electric telescopic rod 4 are all prior arts, wherein the gasification liquid nitrogen freezer 1 is a non-direct contact freezing device in the prior art, and the temperature of the freezing environment is mainly adjusted by controlling the injection amount and rate of liquid nitrogen, so that food can be quickly frozen in a low-temperature but controllable environment, and at the same time, it is ensured that the surface of the processing end is not directly affected by the extremely low temperature of liquid nitrogen, thereby protecting the structure and taste of the food. As shown in the accompanying drawings, the low-temperature gas will be directly wrapped around the outer side of the sleeve of the electric valve sleeve 2, so that the inside of the sleeve It has a low temperature environment, and the configured electric valve sleeve 2 is a sleeve structure with high conductivity in the prior art, and a servo electric valve in the prior art is fixedly installed on the top of the sleeve for automatically opening and closing the sleeve. The configured first electric telescopic rod 4 can control the disc bracket 5 at its output end to approach one end of the electric valve sleeve 2 through the telescopic state of the output end, on the one hand, it is used to move the auxiliary reagent injection mechanism 8 to the processing surface, and on the other hand, it is used to approach the electric adsorption module 15 on one end of the electric valve sleeve 2 to flatten the abalone on the adsorption end of the electric adsorption module 15, so that the outer edge tissue of the abalone can be better penetrated by the auxiliary reagent injection mechanism 8, and the so-called electric adsorption module 15 is an adsorption device that can be controlled by pneumatic adsorption in the prior art, which can adsorb the abalone on the output end, and only needs to cooperate with the electric crawler and the multi-axis mechanical arm to transport the abalone to the adsorption end of the electric adsorption module 15 on the production line;

[0050] The above technical scheme is specifically as follows: the abalone is transported to the adsorption end of the electric adsorption module 15 by only cooperating with the electric crawler and the multi-axis mechanical arm on the production line, and then the disc bracket 5 at the output end is controlled by the first electric telescopic rod 4 configured on the lifting bracket 3 to adaptively approach the electric adsorption module 15, and after being close to the abalone, the auxiliary reagent injection mechanism 8 is configured on the annular partition plate 7 through the driving action of the driving mechanism 9 and in cooperation with each linkage gear module 96, so that the auxiliary reagent injection mechanism 8 is close to the flattened abalone and slowly inserted into the inside of the abalone, and then the auxiliary reagent injection mechanism 8 is injected into the auxiliary reagent injection mechanism 8. Into the abalone, finally retract the disc support 5, open the gasification type liquid nitrogen freezer 1 to freeze the electric valve sleeve 2, by injecting antifreeze or protective agent into the abalone, the formation of large ice crystals can be effectively reduced in the freezing process, the delicate structure inside the abalone is maintained, the elasticity and mouthfeel after thawing are enhanced, and antifreeze or other protective agents can be accurately injected into the abalone, these additives help to lower the freezing point and inhibit ice crystal growth, further guarantee the cell integrity and product consistency in the freezing process, and realize the uniform rapid freezing of abalone in the case of non-direct contact. This design avoids the problem of excessively fast freezing of the surface caused by direct contact during traditional liquid nitrogen quick freezing, thereby reducing the internal and external temperature difference, and preventing the formation of large ice crystals from destroying the cell structure.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the bottom of the disc bracket 5 is fixedly connected to a plurality of suspension rods 6 in a circular manner, and a circular baffle 7 which is concentric with the disc bracket 5 is fixedly connected at the bottom position of the suspension rod 6, and a sliding groove 12 is fixedly connected to the circular baffle 7 at the position exactly at the bottom of each sector-shaped storage tank 11, and the auxiliary reagent injection mechanism 8 includes a sliding clamp 81 slidably installed in each sliding groove 12, and a syringe 82 is fixedly connected to the bottom of the sliding clamp 81, and a detachable injection head 83 is mounted on the side of the syringe 82 facing the center of the circular baffle 7, and a connecting valve head 84 which is connected to the inside of the syringe 82 is fixedly connected to the upper surface of the syringe 82, and a conduit which is connected to the bottom of the sector-shaped storage tank 11 directly above is arranged on the outer side of each connecting valve head 84.

[0052] Among them, the configured annular partition 7 is fixedly installed on the bottom of the disc bracket 5 through a plurality of suspension rods 6, and the whole serves as a support for the auxiliary reagent injection mechanism 8, and the sliding groove 12 is used to act as a guide rail, so that the injection barrel 82 can move back and forth along the groove under the action of driving, that is, it can move back and forth toward the center of the annular partition 7, to get closer to the center of the annular partition 7 and away from the center of the annular partition 7, and the connecting valve head 84 configured on the injection barrel 82 is used to connect the fan-shaped storage tank 11 on the same side.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a piston push rod 86 is inserted and installed inside the injection barrel 82, and a first bending rod 87 is fixedly connected to the outer side of the piston push rod 86 extending out of the injection barrel 82, and a first tooth plate 88 is fixedly connected to the outer side of the first bending rod 87, and the first tooth plate 88 is parallel to the extending direction of the detachable injection head 83. A second bending rod 89 is fixedly installed on the upper surface of the sliding clamp 81, and a second tooth plate 810 is fixedly connected to the outer side of the second bending rod 89, and the second tooth plate 810 is also parallel to the extending direction of the detachable injection head 83.

[0054] Among them, the configured syringe 82, detachable injection head 83, and piston push rod 86 as a whole constitute the structure of a syringe in the prior art. When the piston push rod 86 is pushed toward the side of the detachable injection head 83, the auxiliary reagent inside the syringe 82 can be squeezed out, and when the piston push rod 86 retracts, a negative pressure can be formed inside the syringe 82, so that the reagent in the fan-shaped storage tank 11 on the same side is replenished into the syringe 82, and the cycle is repeated in sequence without manual replenishment of the reagent one after another.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, the driving mechanism 9 also includes a fifth bending rod 97 fixedly mounted on the side of each sliding slot 12, and each of the protruding ends of the fifth bending rod 97 is movably mounted with a support rod 98 perpendicular to the surface of the annular partition 7, and one end of the support rod 98 that is in contact with the annular partition 7 is fixedly mounted with a fourth gear plate 910, and each fourth gear plate 910 is meshed with the second gear plate 810 on the same side, and the end of the support rod 98 away from the fourth gear plate 910 is fixedly mounted with a third gear plate 99.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a group of soft rubber partitions 85 are fixedly installed inside the connecting valve head 84. The soft rubber partitions 85 are a disc structure composed of four fan-shaped tough rubber sheets. The outer side surfaces of the piston push rod 86 inserted into the injection barrel 82 are provided with convex buckles, and the inner wall of the injection barrel 82 is also provided with grooves for the convex buckles of the outer side surfaces of the piston push rod 86 to slide and fit. An arc-shaped extrusion plate 10 is fixedly connected at the bottom center position of the disc bracket 5. The outer side surfaces of the fan-shaped storage tanks 11 are all transparent capacity plate structures in a visible state, and are all equipped with sealing covers for replenishing reagents.

[0057] Among them, the soft rubber partition 85 arranged inside the connecting valve head 84 is a disc structure composed of four fan-shaped tough rubber sheets. The four fan-shaped tough rubber sheets are in a sealed state under normal conditions, that is, the four fan-shaped tough rubber sheets are tightly attached. However, when the extrusion pressure on both sides of the four fan-shaped tough rubber sheets changes, the four fan-shaped tough rubber sheets will turn outward toward the corresponding side. For example, when the piston push rod 86 retreats and a negative pressure is formed inside the injection barrel 82, the four fan-shaped tough rubber sheets will turn outward toward one side of the injection barrel 82, so that the reagent in the fan-shaped storage tank 11 is sucked into the injection barrel 82. The convex buckle set on the outer side surface of the piston push rod 86 inserted into the injection barrel 82 and the notch formed on the inner wall of the injection barrel 82 are to ensure that during the forward and backward movement of the piston push rod 86, it will not rotate as a whole during the extension and retraction process, so as to avoid the first bending rod 87 and the first tooth plate 88 on the outside from being offset and disengaged.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, the driving mechanism 9 also includes a first gear plate 92 fixedly mounted on the output end of the servo motor 91, and a plurality of third bending rods 93 are fixedly connected in a circular manner on the outer annular surface of the disc bracket 5, and an arc tray rack 94 is fixedly mounted on the outer side of the third bending rod 93, and each arc tray rack 94 is movably mounted with a double-sided gear ring 95 at the bottom of the disc bracket 5, and the double-sided gear ring 95 is concentric with the disc bracket 5, and the outer ring teeth of the double-sided gear ring 95 mesh with the first gear plate 92.

[0059] The configured double-sided gear ring 95 is a ring with teeth on both the outer and inner rings, and the structure composed of the third bending rod 93 and the arc-shaped tray frame 94 is used to movably install the double-sided gear ring 95.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the driving mechanism 9 also includes several groups of linkage gear modules 96 fixedly mounted on the outer edge of the disc bracket 5, and the linkage gear modules 96 include a fourth bending rod 961, and a second gear plate 962 is movably mounted on the protruding end of the fourth bending rod 961, and the second gear plates 962 in each group are meshed with the inner ring teeth of the double-sided gear ring 95, and an extension rod 963 is fixedly mounted at the bottom center position of the second gear plate 962, and the bottom of the extension rod 963 is fixedly connected to the first special-shaped gear plate 964, and the bottom of the first special-shaped gear plate 964 is fixedly connected to the second special-shaped gear plate 965.

[0061] Among them, the configured linkage gear module 96 is used to play a linkage role. On the one hand, it is used to engage the first gear plate 92 on one side of the servo motor 91, and on the other hand, it is used to drive the auxiliary reagent injection mechanism 8 to perform injection, so that the entire device forms an integrated structure, ensuring the stability of the driving end and the flow effect of the mechanisms on each side during operation.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, the first special-shaped gear plate 964 is a gear plate structure with a 180-degree tooth opening on the outer circular edge, and the first special-shaped gear plate 964 is meshed and corresponding with the third gear plate 99, and the second special-shaped gear plate 965 is also a gear plate structure with a 180-degree tooth opening on the outer circular edge, and the tooth opening on the outer circular edge of the second special-shaped gear plate 965 is arranged in an opposite direction to the tooth opening on the outer circular edge of the first special-shaped gear plate 964, the second special-shaped gear plate 965 is flush with the first tooth plate 88, and the tooth opening of the second special-shaped gear plate 965 and the tooth opening of the first tooth plate 88 are located on the same straight line.

[0063] Among them, the first special-shaped gear plate 964 and the second special-shaped gear plate 965 are configured with the same structure as a whole, but the tooth openings on the outer ring edge are arranged in opposite directions, wherein the first special-shaped gear plate 964 meshes with the third gear plate 99 to drive the third gear plate 99 to rotate, and the second special-shaped gear plate 965 meshes with the fourth gear plate 910. Since the meshing ends have only a 180-degree arc, when the second special-shaped gear plate 965 rotates one circle, the second special-shaped gear plate 965 actually only rotates half a circle. Since the outer arc size of the second special-shaped gear plate 965 is larger than that of the fourth gear plate 910, and the overall length is the same as that of one side of the second tooth plate 810, the meshed second tooth plate 810 will be completely pushed out when it rotates one circle, and the injection cylinder 82 on one side of the sliding clamp 81 is controlled to move as a whole along the sliding groove 12 toward the side of the center of the annular partition plate 7, that is, the detachable injection head 8 is controlled. 3 moves toward one side of the center abalone to slowly insert the detachable injection head 83 into the abalone, and after the syringe 82 is moved into place, that is, after one side of the second tooth plate 810 is completely pushed out, the first tooth plate 88 connected by the first bending rod 87 on the syringe 82 just moves to one side of the first special-shaped gear disk 964 and meshes with the side of the first special-shaped gear disk 964, because the first special-shaped gear disk 964 and the second special-shaped gear disk 965 are identical in structure as a whole, but the tooth openings on the outer annular edge are arranged in opposite directions, so after the second special-shaped gear disk 965 is disengaged from the meshing state, its first special-shaped gear disk 964 is meshed with the first tooth plate 88 again to drive the first tooth plate 88 to move, and driven by the meshing end, one end of the first tooth plate 88 moves together with the first bending rod 87 to one side of the center of the circle of the annular partition plate 7 to drive the piston push rod 86 to inject the injection reagent in the syringe 82;

[0064] Specifically, the servo motor 91 drives the first gear plate 92 at its output end to rotate counterclockwise. Under the clockwise rotation of the first gear plate 92, the meshing double-sided gear ring 95 rotates clockwise. Under the clockwise rotation of the double-sided gear ring 95, each meshing second gear plate 962 will also rotate clockwise. Similarly, the first special-shaped gear plate 964 and the second special-shaped gear plate 965 at the bottom of the second gear plate 962 will also rotate clockwise. 5 is meshed with the third gear plate 99, so when the second special-shaped gear plate 965 rotates clockwise, the third gear plate 99 rotates counterclockwise, so the fourth gear plate 910 coaxial with the third gear plate 99 will also rotate counterclockwise under the action of linkage, and rely on the counterclockwise rotation characteristic of the fourth gear plate 910 to bring out the meshed second tooth plate 810, so that each second tooth plate 810 drives the injection cylinder 82 to move along the sliding notch 12 toward the center of the annular partition plate 7, so as to insert the detachable injection head 83 into On the abalone at the center of the circle, after the injection cylinder 82 is fully extended, the second special-shaped gear plate 965 is disengaged from the third gear plate 99. At this time, the second special-shaped gear plate 965 continues to rotate to make the first special-shaped gear plate 964 mesh with the first toothed plate 88 close to it. Therefore, in the second half of the circle, the first special-shaped gear plate 964 will be driven to pull the first toothed plate 88 to continue to move, so that each first toothed plate 88 drives the piston push rod 86 to continue to move toward the center of the annular partition 7 to control the detachable The injection head 83 injects the auxiliary reagent. After the first special-shaped gear plate 964 rotates half a circle, which is equivalent to the second gear plate 962 rotating one circle, the output end of the servo motor 91 drives in the reverse direction to make the whole device retreat. During the retreat process, the piston push rod 86 is withdrawn from the inside of the injection barrel 82, so that a negative pressure is formed inside the injection barrel 82, and the reagent in each fan-shaped storage tank 11 is sucked into the injection barrel 82 in a state where the soft rubber partition 85 is turned inward and outward, so that an abalone can be frozen.

[0065] As for one end of the electric valve sleeve 2, in the process of working with the gasification type liquid nitrogen freezer 1, firstly, the first electric telescopic rod 4 controls the output end disc bracket 5 to be retracted, so that the whole device is lifted upward to ensure that the electric valve on the electric valve sleeve 2 can be closed without interference, and then the electric adsorption module 15 is retracted through the second electric telescopic rod 13 inside the electric valve sleeve 2, so that the electric adsorption module 15 extends into the inside of the electric valve sleeve 2, and cooperates with the closed electric valve sleeve 2 and the gasification type liquid nitrogen freezer 1 to perform gasification type liquid nitrogen freezing on it;

[0066] In particular, before the reagent is injected, when the disc bracket 5 extends downwardly from the first electric telescopic rod 4, the abalone at the end of the electric adsorption module 15 is flattened in the process of being fitted with the electric adsorption module 15, and the abalone in the flattened state can better wait for the injection of the syringes on the four sides, so that the auxiliary reagent can be accurately injected into the inside; and after the reagent is injected, in order to ensure the fluidity and complete mixing of the injected reagent, the vibration module 14 can be turned on, and the vibration module 14 is a device with high-frequency vibration in the prior art, which can make the abalone at the adsorption end vibrate at a high frequency, accelerate the complete mixing of the injected reagent, and is different from the direct freezing of the liquid nitrogen quick-freezer in the prior art. It can better ensure the uniformity of the frozen end and is more suitable for the freezing processing of high-quality abalone such as soft-boiled abalone.

[0067] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a second electric telescopic rod 13 is fixedly installed at the center of the inner bottom circle of the electric valve sleeve 2, a vibration module 14 is fixedly connected to the output end of the second electric telescopic rod 13, and an electric adsorption module 15 is fixedly installed on the output end of the vibration module 14.

[0068] A method for using a freezing device for a soft-boiled abalone processing technology comprises the following steps:

[0069] S1: First, the fresh abalone is transported to the electric adsorption module 15 through the electric crawler and the multi-axis robot arm, and is pneumatically adsorbed and fixed by the module; then, the first electric telescopic rod 4 controls the disc bracket 5 to descend, flattening the abalone for subsequent injection operation;

[0070] S2: Then, the servo motor 91 drives the bilateral gear ring 95 and drives the auxiliary reagent injection mechanism 8 through the linkage gear module 96; the injection mechanism moves along the sliding notch 12 to the abalone and is inserted into the abalone; the piston push rod 86 pushes the injection cylinder 82 to extract the antifreeze agent or protective agent from the fan-shaped storage tank 11 and inject it into the abalone;

[0071] S3: Then, the first electric telescopic rod 4 retracts the disc support 5 to make room for the freezing step; the second electric telescopic rod 13 retracts the electric adsorption module 15 to make it enter the electric valve sleeve 2; the gasification liquid nitrogen freezer 1 is started, and the low-temperature gas indirectly cools the abalone through the electric valve sleeve 2 to ensure uniform freezing;

[0072] S4: Finally, the vibration module 14 is turned on to perform high-frequency vibration on the abalone to promote uniform distribution of the auxiliary reagent. After that, the gasification liquid nitrogen freezer 1 is continued to be used for final freezing until the desired state is reached to ensure that the abalone is uniformly frozen inside and outside.
