Description

Technical Field

[0001] The present application relates to the technical field of seaweed deodorization, and in particular to a device and process for deodorization of seaweed dietary fiber by microbial fermentation. Background Art

[0002] Seaweed is rich in dietary fiber, such as alginate, carrageenan, agar and other polysaccharides, which show broad application prospects in the fields of food, health care products and medicine. However, natural seaweed has a strong and special fishy smell. This unpleasant flavor greatly limits the amount of seaweed dietary fiber added in the end product and its acceptability, becoming a barrier that needs to be overcome in expanding its application market.

[0003] For example, a seaweed deodorization device and a deodorization method for preventing nutrient loss, disclosed in publication number CN118947941A, relate to the technical field of seaweed deodorization. The prior art provides a deodorization component that can drive the seaweed to stir while deodorizing the seaweed, so that the seaweed is in full contact with the first deodorization solution and the second deodorization solution, thereby deodorizing the seaweed to prevent nutrient loss, thereby increasing the deodorization effect of the seaweed deodorization device.

[0004] However, the above-mentioned prior art still has some defects when it comes to snake breeding: 1. Since the protrusion in the filter ring plate in the above-mentioned patent application is only provided on half of the inner surface of the filter ring plate, and no anti-adhesion mechanism is provided on the protrusion, seaweed may adhere to the protrusion, making it easy for the seaweed to accumulate in the filter ring plate, making it impossible for the existing device to effectively clean the seaweed or effectively remove the fishy smell of the seaweed.

[0005] 2. In the above patent application, the seaweed is not cut into small pieces before being soaked for deodorization. Since the intact seaweed usually has a large volume and a relatively complete shape, when it is soaked in the deodorization solution, the area where the solution can effectively contact the surface of the seaweed is relatively limited, which leads to poor deodorization effect and failure to fully remove the fishy components in the seaweed.

[0006] 3. In the above patent application, after the seaweed is washed in the first deodorizing solution, the seaweed is directly placed in the second deodorizing solution for deodorizing without draining the seaweed. This will cause the concentration of the second deodorizing solution to be diluted, thereby making it impossible to achieve the expected deodorizing effect on the seaweed, and resulting in a large amount of fishy smell components remaining in the seaweed.

[0007] Based on this, and according to the above-mentioned viewpoints, there is still room for improvement in the existing technology for removing the fishy smell from seaweed. Summary of the invention

[0008] In order to solve the above technical problems, the present application provides a device and process for removing fishy smell from seaweed dietary fiber by microbial fermentation, which adopts the following technical solutions:

[0020] Preferably, the cleaning and stirring assembly includes a rotating rod, which is rotatably mounted on a corresponding supporting rod along a vertical direction, and a fan is provided at the bottom end of the rotating rod.

[0042] The following is combined with Figures 1 to 11 This application is described in further detail.

[0043] The embodiment of the present application discloses a seaweed dietary fiber microbial fermentation deodorization device, which first places whole seaweed into a shearing mechanism 2, processes the seaweed into small pieces of seaweed, and then places the small pieces of seaweed into a cleaning mechanism 3 for stirring and cleaning, so that the seaweed can maintain a clean state and enter the deodorization mechanism 4 for deodorization treatment, thereby achieving efficient and sufficient deodorization of the seaweed and improving production efficiency.

[0044] Embodiment 1:

[0045] Reference Figure 1 A seaweed dietary fiber microbial fermentation deodorization processing device includes a frame 1, the frame 1 includes two support rings 11, the two support rings 11 are installed at the bottom of the frame 1, and the frame 1 is sequentially installed with a shearing mechanism 2, a cleaning mechanism 3 and a deodorization mechanism 4 along its length direction, and the two support rings 11 are respectively arranged below the cleaning mechanism 3 and the deodorization mechanism 4.

[0046] The whole or large pieces of seaweed are placed in the shearing mechanism 2 and sheared into small pieces of seaweed to avoid the situation where the cell walls and tissues of the large pieces of seaweed are intact in biological structure and organization, which hinders the removal of fishy substances, thereby making it difficult to remove the fishy smell of the seaweed. The seaweed sheared by the shearing mechanism 2 is cleaned by the cleaning mechanism 3, and the cleaned seaweed is placed in the deodorizing mechanism 4 for microbial fermentation and deodorization treatment.

[0047] Both sides of the frame 1 are provided with transverse guide rails 12 along the length direction thereof, and a filter cylinder 5 is slidably installed between the two transverse guide rails 12, and the filter cylinder 5 can move laterally along the transverse guide rails 12. The seaweed cut by the shearing mechanism 2 falls into the filter cylinder 5, and the filter cylinder 5 moves along the transverse guide rails 12 to the bottom of the cleaning mechanism 3, so that the cleaning mechanism 3 can clean the seaweed in the filter cylinder 5. After the cleaning, the filter cylinder 5 continues to move along the transverse guide rails 12 to the bottom of the deodorizing mechanism 4, so that the deodorizing mechanism 4 can perform microbial fermentation and deodorization treatment on the seaweed in the filter cylinder 5.

[0048] The frame 1 is provided with two symmetrically distributed lifting guide rails 15 corresponding to the shearing mechanism 2, the cleaning mechanism 3 and the deodorizing mechanism 4, and the lifting guide rails 15 extend longitudinally, and the transverse guide rails 12 are longitudinally slidably installed on the lifting guide rails 15, and a support rod 16 is slidably provided between the two lifting guide rails 15 corresponding to the cleaning mechanism 3 and the deodorizing mechanism 4.

[0049] One of the transverse guide rails 12 is rotatably penetrated with a threaded rod 13, which is threadedly connected with the filter cylinder 5, and the other transverse guide rail 12 is rotatably penetrated with a sliding rod 14, which is slidably matched with the filter cylinder 5. The filter cylinder 5 is driven to move along the transverse guide rail 12 by driving the threaded rod 13, and the filter cylinder 5 slides on the sliding rod 14.

[0050] Reference Figure 1 The cleaning mechanism 3 includes a cleaning cylinder 31 and a cleaning stirring assembly 32 . The cleaning cylinder 31 is installed in the corresponding support ring 11 , and the cleaning stirring assembly 32 is arranged above the cleaning cylinder 31 .

[0051] See also Figure 1 and Figure 5 The cleaning and stirring assembly 32 includes a rotating rod 321, which is rotatably installed on the corresponding support rod 16 along the vertical direction, and a fan 322 is provided at the bottom end of the rotating rod 321. A first motor 17 is installed on the top of the support rod 16, and the driving end of the first motor 17 is connected to the rotating rod 321 by a bevel gear meshing method.

[0052] During specific operation, the sheared small pieces of seaweed fall into the filter drum 5. Driven by an external power (not shown in the figure), the threaded rod 13 rotates, and then the filter drum 5 can move along the transverse guide rail 12 to the cleaning mechanism 3, and then the filter drum 5 descends along the lifting guide rail 15 to enter the cleaning cylinder 31. At this time, the cleaning and stirring assembly 32 also moves down along the lifting guide rail 15 and penetrates into the filter drum 5, and then the fan 322 is driven to rotate by the rotating rod 321, so as to facilitate the cleaning of the seaweed in the filter drum 5. At the same time, after the cleaning is completed, the filter drum 5 and the cleaning and stirring assembly 32 move up and reset, and the filter drum 5 begins to drain the seaweed. At this time, the rotating rod 321 can drive the fan 322 to air-dry the cleaned seaweed, ensuring that the seaweed can enter the deodorizing mechanism 4 for deodorizing treatment in a dry state, thereby preventing the cleaning liquid contaminated on the seaweed from diluting the deodorizing liquid in the deodorizing mechanism 4, thereby weakening the deodorizing effect of the deodorizing liquid.

[0053] The deodorizing mechanism 4 comprises a deodorizing cylinder 41, which is installed in the corresponding support ring 11, and a deodorizing stirring assembly 42 is arranged above the deodorizing cylinder 41. The deodorizing stirring assembly 42 can help the deodorizing cylinder 41 to fully deodorize the seaweed.

[0054] The dried seaweed is moved to the top of the deodorizing cylinder 41 along with the filter cylinder 5 through the transverse guide rail 12, and then the filter cylinder 5 descends along the corresponding lifting guide rail 15 and enters the deodorizing cylinder 41. The deodorizing stirring component 42 also enters the deodorizing cylinder 41 to stir the deodorizing liquid and the seaweed mixture, so that the seaweed can be fully mixed and contacted with the deodorizing liquid, thereby completely deodorizing the seaweed. The deodorized seaweed rises to its original position along the lifting guide rail 15 and is drained.

[0055] Reference Figure 7 and Fig. 9 In order to keep the microorganisms in the deodorizing liquid active at a high level and effectively soak and deodorize the seaweed, the deodorizing stirring assembly 42 includes a rotating rod 421 rotatably arranged on the corresponding support rod 16, a ventilation cavity 4217 is provided inside the rotating rod 421, and an air inlet 422 connected to the ventilation cavity 4217 is provided at the top of the rotating rod 421. By supplying gas to the air inlet 422, the gas can enter the deodorizing liquid through the ventilation cavity 4217 to increase the oxygen content of the deodorizing liquid, thereby increasing the activity of the microorganisms in the deodorizing liquid.

[0056] Reference Figure 7 , Figure 8 and Fig. 9The bottom end of the ventilation cavity 4217 is connected with a plurality of jet pipes 423 along its circumferential direction. A plurality of nozzles 424 are evenly installed along the length direction of the jet pipe 423 on the side of the jet pipe 423 away from the deodorizing cylinder 41. The jet pipe 423 is symmetrically installed with two fan blades 425 along its circumferential direction. When the rotating rod 421 rotates, the jet pipe 423 is driven to rotate, and the jet pipe 423 drives the fan blades 425 to rotate to stir the seaweed and complete air drying after deodorization.

[0057] Reference Figure 1 and Figure 3 , wherein a second motor 18 is disposed on the top of the support rod 16 , and a driving end of the second motor 18 and the rotating rod 421 are meshed and connected via a bevel gear.

[0058] During the specific implementation, when the deodorizing stirring assembly 42 stirs the deodorizing liquid, the second motor 18 drives the rotating rod 421 to rotate, and the rotating rod 421 drives the jet pipe 423 and the fan blade 425 to rotate synchronously, stirring the seaweed in the deodorizing liquid to improve the deodorizing efficiency. At the same time, oxygen is transported to the ventilation cavity 4217 through the air inlet 422 of the rotating rod 421, and the oxygen enters the deodorizing liquid through the nozzle 424 of the jet pipe 423, so that the oxygen content in the deodorizing liquid is increased, and then the activity of the microorganisms is enhanced, thereby accelerating the deodorizing rate of the seaweed by the microorganisms and improving the production efficiency of the deodorized seaweed.

[0059] After the seaweed is deodorized, as the filter cylinder 5 rises along the lifting guide rail 15 to drain the seaweed inside, the second motor 18 drives the rotating rod 321 to rotate again, and the rotating rod 321 drives the fan blades 425 to rotate by driving the jet pipe 423. The wind generated by the rotation of the fan blades 425 can dry the seaweed in the filter cylinder 5.

[0060] Reference Figure 4 In order to enable the filter cylinder 5, the cleaning and stirring assembly 32 and the deodorizing and stirring assembly 42 to be lifted and lowered synchronously along the lifting guide rail 15, the two matching lifting guide rails 15 are provided with sliding grooves 19 on their longitudinal opposite sides, and a scissor-type structure 6 is longitudinally slidably installed along the sliding groove 19, and the single-point hinge on the scissor-type structure 6 is respectively connected to the filter cylinder 5 and the transverse guide rail 12.

[0061] During the specific implementation process, when the seaweed in the filter cylinder 5 is cleaned, driven by an external power (not shown in the figure), the scissor structure 6 can shrink and bring the filter cylinder 5 and the cleaning and stirring assembly 32 down synchronously, and the scissor structure 6 can make the distance between the filter cylinder 5 and the cleaning and stirring assembly 32 gradually decrease when they descend, so that the cleaning and stirring assembly 32 can stir and clean the seaweed in the filter cylinder 5. After the seaweed is cleaned, the scissor structure 6 extends and brings the filter cylinder 5 and the cleaning and stirring assembly 32 up synchronously, and the scissor structure 6 can make the distance between the filter cylinder 5 and the cleaning and stirring assembly 32 gradually increase when they rise, so that when the filter cylinder 5 moves to the deodorizing mechanism 4 through the transverse guide rail 12, it will not be hindered by the cleaning and stirring assembly 32, so that the seaweed cleaning process can be carried out smoothly and efficiently.

[0062] Embodiment 2:

[0063] Based on Example 1, refer to Figure 5 In order to enable the cleaning and stirring assembly 32 to stir the cleaning liquid and the seaweed, the rotating rod 321 is connected to a plurality of rotating shafts 323 through bevel gear meshing, and the rotating rod 321 is provided with a plurality of rotating shafts 323 along its circumference, and a cleaning blade 324 is provided at one end of the rotating shaft 323 away from the rotating rod 321. When the rotating rod 321 rotates, the rotating shaft 323 is driven to rotate through the bevel gear transmission, thereby causing the cleaning blade 324 to rotate and fully stir the cleaning liquid and the seaweed.

[0064] Continue to refer to Figure 5 The rotating rod 321 is provided with a protective shell 325 along its axial direction, and the rotating shaft 323 is rotatably provided in the protective shell 325. The protective shell 325 can prevent the seaweed from winding the bevel gear set used for transmission, so that the cleaning blade 324 cannot rotate.

[0065] During the specific implementation process, the rotating rod 321 rotates, and the rotating shaft 323 is driven to rotate through the bevel gear transmission, and the rotating shaft 323 drives the cleaning blade 324 to rotate, so that the cleaning blade 324 can rotate while revolving around the rotating rod 321, so as to ensure that the cleaning blade 324 can not only allow the cleaning liquid to fully clean the seaweed, but also reduce the situation where the seaweed adheres to the surface of the cleaning blade 324, thereby avoiding the seaweed from being unable to be fully cleaned, so as to reduce the output of the finished product of deodorized seaweed.

[0066] Embodiment three:

[0067] Based on the first and second embodiments, refer to Figure 5 and Figure 6, in order to further prevent seaweed from adhering to the surface of the cleaning blade 324, limit blocks 326 are installed at both ends of the cleaning blade 324 along its length direction. A scraping block 327 is inserted between the two limit blocks 326 on the cleaning blade 324. A return spring 328 is installed between the scraping block 327 and the limit block 326 close to the rotating rod 321. The scraping block 327 can scrape the seaweed on the cleaning blade 324 under the action of centrifugal force, and the return spring 328 resets the scraping block 327.

[0068] During the specific implementation process, the centrifugal force generated when the rotating rod 321 rotates drives the scraping block 327 to move away from the rotating rod 321, so that the scraping block 327 can scrape the seaweed on the cleaning blade 324. After the rotating rod 321 stops rotating, the return spring 328 pulls the scraping block 327 back to its original position, so that the scraping block 327 can scrape the seaweed on the cleaning blade 324 again. At the same time, with the cooperation of the self-rotation of the cleaning blade 324 itself, no seaweed will adhere to the cleaning blade 324, ensuring that the output of the deodorized seaweed product remains unchanged.

[0069] Embodiment 4:

[0070] On the basis of Embodiment 1, Embodiment 2 and Embodiment 3, referring to Figure 7 and Figure 8 , in order to enable the deodorizing stirring assembly 42 to stir the deodorizing liquid and the seaweed mixture, a plurality of U-shaped support frames 426 are uniformly installed along the circumference of the rotating rod 421. A plurality of rotating shafts 427 are rotatably installed between the vertical ends of the support frames 426 and the rotating rod 421. Deodorizing blades 428 are installed on the rotating shafts 427. When the rotating rod 421 rotates, it drives the rotating shafts 427 to rotate, and then the rotating shafts 427 drive the deodorizing blades 428 to rotate, so as to stir the seaweed and deodorizing liquid mixture in the deodorizing cylinder 41.

[0071] During the specific implementation process, when the rotating rod 421 rotates, it drives the support frames 426 and the rotating shafts 427 to rotate, and then drives the deodorizing blades 428 to rotate. When the deodorizing blades 428 rotate, they can stir the seaweed and deodorizing liquid mixture, so that the seaweed can be fully mixed and reacted with the microorganisms in the deodorizing liquid, accelerating the reaction rate between the seaweed and the deodorizing liquid, so that all the deodorizing substances in the seaweed can be removed completely.

[0072] Referring to Figure 7 , in order to make the inside of the deodorizing cylinder 41 a closed environment when the seaweed is undergoing the deodorizing reaction, a sealing cover 429 is inserted through the top end of the rotating rod 421. The sealing cover 429 can cover the deodorizing cylinder 41 to ensure that the inside of the deodorizing cylinder 41 is a closed environment.

[0073] Referring to Figure 8A plurality of convex points 4218 are arranged on the surface of one side of the deodorizing blade 428 close to the sealing cover 429. The convex points 4218 can always maintain an air layer between the seaweed adhering to the deodorizing blade 428 and the deodorizing blade 428, so that the seaweed can be separated from the deodorizing blade 428.

[0074] Among them, two horizontally arranged hanging rods are symmetrically provided on the top of the filter cylinder 5, and the filter cylinder 5 is slidably set on the transverse guide rail 12 through the hanging rods. The sealing cover 429 and the deodorizing cylinder 41 are provided with corresponding sealing grooves 4210 at the hanging rods of the filter cylinder 5 corresponding to the filter cylinder 5. The sealing grooves 4210, the sealing cover 429 and the deodorizing cylinder 41 cooperate with each other to make the deodorizing cylinder 41 a closed environment, thereby ensuring the smooth progress of the seaweed deodorization reaction.

[0075] During the specific implementation process, when the rotating rod 421 descends along the lifting guide rail 15, it can drive the sealing cover 429 to descend together, and finally the sealing cover 429 completes the sealing of the deodorizing cylinder 41, so that the interior of the deodorizing cylinder 41 is a closed environment when the seaweed and the deodorizing liquid react, and the deodorizing liquid will not be disturbed by external substances when reacting with the fishy substances in the seaweed. The closed environment can also fully guarantee the activity of microorganisms, thereby accelerating the reaction rate and improving the efficiency of seaweed deodorization.

[0076] When the deodorizing blade 428 rotates in the deodorizing cylinder 41 to stir the deodorizing liquid and the seaweed mixture, the protrusions 4218 on the deodorizing blade 428 can ensure that the seaweed adhered to the deodorizing blade 428 always maintains an air layer between it and the surface of the deodorizing blade 428, so that when the deodorizing blade is impacted by the water flow during rotation, the seaweed can be easily washed away by the water flow, so that the fishy substances in the seaweed can fully react with the deodorizing liquid, and the output of the deodorized seaweed product will not be reduced.

[0077] Embodiment five:

[0078] Based on the first, second, third and fourth embodiments, refer to Fig.10 and Fig.11 In order to further enhance the anti-algae adhesion effect of the deodorizing blade 428 and ensure that the output of the deodorizing seaweed product will not be reduced, hinge blocks 4211 are installed at both ends of the top of the deodorizing blade 428, and a hinge rod 4212 is installed between the hinge blocks 4211 of two adjacent deodorizing blades 428 in the height direction of the rotating rod 421. The hinge rod 4212 can control the two processes of stirring and de-algae of the deodorizing blade 428 by controlling the rotation degree of the deodorizing blade 428.

[0079] During the specific implementation process, when the hinged rod 4212 synchronously pulls the deodorizing blades 428 upwards, the deodorizing blades 428 form a slightly inclined vertical state. At this time, the resistance of the deodorizing blades 428 to water increases when they rotate, and then the deodorizing blades 428 in this state can stir the deodorizing liquid, so that the deodorizing liquid can be fully mixed with the seaweed, thereby enabling the deodorizing liquid to remove the deodorizing substances in the seaweed, so as to achieve efficient deodorization of the seaweed.

[0080] When the hinged rod 4212 synchronously pushes the deodorizing blade 428 downward, the deodorizing blade 428 tends to be in a straight state. At this time, the resistance of the deodorizing blade 428 to water is reduced when it rotates, and thus the deodorizing blade 428 in this state cannot stir the deodorizing liquid. At the same time, due to the impact of the water flow, the seaweed on the deodorizing blade 428 in a straight state can be washed away, so that no seaweed will adhere to the deodorizing blade 428. Therefore, with the cooperation of the convex point 4218 and the hinged rod 4212 in pushing and pulling the deodorizing blade 428, the deodorizing blade 428 can achieve anti-seaweed adhesion treatment of the seaweed, so as to ensure that the output of the deodorized seaweed product will not be reduced.

[0081] Reference Fig.11 In order to enable the hinged rod 4212 to achieve the push-pull effect on the deodorizing blade 428, the hinged block 4211 closest to the sealing cover 429 is rotatably mounted with a traction rod 4213, and the end of the traction rod 4213 away from the hinged block 4211 is mounted with a roller 4214, and the roller 4214 is in rolling connection with the sealing cover 429. The roller 4214 can roll circumferentially along the sealing cover 429 at the bottom of the sealing cover 429, thereby driving the traction rod 4213 to guide the push-pull of the hinged rod 4212.

[0082] Reference Fig.11 In order to make the traction rod 4213 always maintain a vertical state, and thus effectively drive the deodorizing blade 428 to rotate, vertical guide frames 4219 are rotatably installed on both sides of the top of the traction rod 4213 along its movement direction, and a vertical guide wheel 4220 is rotatably installed on one end of the vertical guide frame 4219 close to the sealing cover 429, and a return spring 4221 is installed between the vertical guide frame 4219 and the traction rod 4213. The return spring 4221 can make the vertical guide frame 4219 move toward the sealing cover 429, thereby prompting the two vertical guide wheels 4220 to always roll close to the sealing cover 429, so that the two vertical guide wheels 4220 form a triangular support frame structure on both sides of the traction rod 4213, which can keep the traction rod 4213 in a vertical shape to ensure that the deodorizing blade 428 can always be pushed and pulled by the traction rod 4213.

[0083] Reference Fig.10 and Fig.11A semi-ring convex block 4215 is provided on the rolling path of the corresponding roller 4214 at the bottom of the sealing cover 429. When the roller 4214 rolls onto the semi-ring convex block 4215, the traction rod 4213 descends and causes the hinge rod 4212 to descend synchronously.

[0084] During the specific implementation process, when the rotating rod 321 rotates, it drives the roller 4214 to rotate circumferentially along the sealing cover 429. When the roller 4214 rolls to the semi-ring protrusion 4215, the roller 4214 pushes the traction rod 4213 to descend, and the traction rod 4213 simultaneously drives the hinged rod 4212 to descend, and then the hinged rod 4212 makes the deodorizing blade 428 in a straight state. Under the impact of water flow, the deodorizing blade 428 can self-clean so that seaweed will not adhere to its surface, thereby ensuring the yield of deodorized seaweed while promoting the deodorizing reaction process of the seaweed.

[0085] When the roller 4214 rolls on the lower surface of the sealing cover 429, the roller 4214 pulls the traction rod 4213, and the traction rod 4213 simultaneously pulls the hinged rod 4212, so that the deodorizing blades 428 are all in a slightly inclined vertical state. In this state, the deodorizing blades 428 have a stirring effect on the deodorizing liquid when rotating, so that the seaweed can be fully mixed with the deodorizing liquid, thereby accelerating the reaction rate of the two and improving production efficiency.

[0086] Reference Fig.11 In order to enable the roller 4214 to roll along the sealing cover 429 and the semi-ring convex block 4215, thereby changing the function of the deodorizing blade 428, a tension spring 4216 is connected to one end of the deodorizing blade 428 close to the hinge block 4211 and the upper horizontal end of the support frame 426. The tension spring 4216 can always maintain the pulling effect on the deodorizing blade 428, so that the roller 4214 can always roll on the sealing cover 429 and the semi-ring convex block 4215.

[0087] During the specific implementation process, when the roller 4214 rolls onto the semi-ring protrusion 4215, the tension on the tension spring 4216 is relatively large, so that the roller 4214 can always roll close to the semi-ring protrusion 4215. When the roller 4214 rolls to the lower surface of the sealing cover 429, the tension of the tension spring 4216 is relatively small, but the roller 4214 can still move in a circular motion close to the sealing cover 429, thereby adjusting the state change of the deodorizing blades 428 and improving the deodorizing efficiency of seaweed.

[0088] Finally, the present invention also provides a seaweed dietary fiber microbial fermentation deodorization treatment process, and the use method thereof comprises the following steps:

[0089] S1: seaweed shearing, putting the whole seaweed into the shearing mechanism 2 for shearing, so that the seaweed is cut into small pieces, and the small pieces of seaweed fall into the filter cylinder 5 below the shearing mechanism 2;

[0090] S2: Soaking and cleaning, the filter cylinder 5 moves to the cleaning mechanism 3 along the transverse guide rail 12, and enters the cleaning cylinder 31 along the lifting guide rail 15 for soaking and cleaning;

[0091] S3: Air-drying and draining. The cleaned seaweed rises along the lifting guide rail 15. At the same time, the fan 322 at the bottom of the cleaning and stirring assembly 32 air-dries the seaweed, and the filter cylinder 5 also drains the seaweed;

[0092] S4: deodorization. The dried seaweed enters the deodorization mechanism 4 through the transverse guide rail 12, and then enters the deodorization cylinder 41 along the lifting guide rail 15, thereby completing the deodorization.

[0093] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
