A device for breaking down and desalting seaweed during processing

Abstract

This utility model belongs to the field of seafood processing technology, specifically a desalting and dispersing device for processing wakame seaweed. It includes an outer cylinder, an inner cylinder, and a turntable. The user can open the outer cylinder's sealed cover and place the salted wakame seaweed into the inner cylinder. The rotation of the inner cylinder can be divided into three stages: a low-speed dispersing stage, where the dispersing rod rotates with the inner cylinder, breaking up clumps and initially separating salt particles; a medium-speed desalting stage, where centrifugal force causes the seaweed to adhere tightly to the inner cylinder wall, and the osmotic pressure difference between the inside and outside of the cells accelerates salt precipitation, with brine collecting along a conical guide channel to the drain valve; and a high-speed fine desalting stage, where residual salt is completely removed, and the high-pressure spray pipe and high-pressure nozzle at the top of the outer cylinder are activated to wash away salt crystals on the surface of the seaweed. The dispersing rod and centrifugal osmotic desalting are carried out simultaneously, shortening processing time and improving the desalting efficiency of the wakame seaweed. After desalting, the drain valve is opened to discharge high-salt wastewater. The spray water is filtered and returned to the inner cylinder for reuse, achieving water reuse through filtration, improving the device's water-saving rate and avoiding excessive water waste.

Description

Technical Field

[0001] This utility model belongs to the field of seafood processing technology, specifically a device for breaking down and desalting seaweed for processing. Background Technology

[0002] In the processing of wakame seaweed, salting is the core technology for extending the shelf life of the raw materials, but subsequent processing requires multiple steps such as dispersing and desalting. Currently, the industry generally uses separate equipment: first, the clumps of salted seaweed are dispersed using a drum-type disperser or manually beaten, then transferred to a basket centrifuge or multi-stage rinsing tank for desalination. However, this method suffers from problems such as process separation, low efficiency, and secondary contamination. Traditional centrifuges lack a targeted dispersing structure, resulting in uneven desalination. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a dispersing and desalting device for processing wakame seaweed, thereby solving the problems of low efficiency and uneven desalination.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a desalting and dispersing device for processing wakame seaweed, characterized in that it includes an outer cylinder, an inner cylinder, and a turntable. The outer cylinder is configured as a closed cylinder with a removable sealing cap at the top and a conical guide groove connected to the bottom. The inner cylinder and the turntable are disposed inside the outer cylinder. The inner cylinder is also configured as a cylindrical perforated roller, coaxial with the outer cylinder. The bottom of the inner cylinder is sealed, and the top is open. The inner wall of the inner cylinder has honeycomb holes evenly distributed, and a spiral guide rail is provided on the inner wall. The turntable is installed at the bottom of the inner cylinder and is protected by a water-proof cover connected to the bottom of the inner cylinder.

[0005] Optionally, multiple dispersing rods are fixed on the spiral guide rail. The dispersing rods are fixed at an angle of 20°-30° to the inner cylinder wall and are arranged in a spiral step pattern following the spiral guide rail.

[0006] Optionally, a connecting flange is installed at the bottom of the turntable, and a motor and an axial machine are installed inside the connecting flange. The axial machine is connected to the turntable through the connecting flange.

[0007] Optionally, a drain valve is provided at the bottom outlet of the conical guide channel, a valve switch is provided on the drain valve, a high-pressure spray pipe is provided at the bottom of the drain valve, a filter box is provided on the outer surface of the outer cylinder, the high-pressure spray pipe passes through the filter box, its tail faces the top of the inner cylinder, and a high-pressure nozzle is provided at the tail of the high-pressure spray pipe, the high-pressure nozzle is detachable and adjustable.

[0008] Optionally, the sealing cover is provided with a pull rod and multiple sliding grooves, and a counterweight is provided in the sliding grooves.

[0009] Optionally, the dispersing rod is provided with a silicone column, and the silicone column is provided with multiple protrusions.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, the user can open the outer cylinder sealing cap, put the salted wakame seaweed into the inner cylinder, and close the sealing cap. The rotation of the inner cylinder can be divided into three stages: a low-speed dispersing stage, where the dispersing rod rotates with the inner cylinder, using the collision, friction, and axial thrust generated by the spiral arrangement of the rod and the seaweed to break up clumps and initially separate salt particles; a medium-speed desalting stage, where centrifugal force makes the seaweed adhere tightly to the inner cylinder wall, and the osmotic pressure difference between the inside and outside of the cells accelerates the salt precipitation, with brine being thrown into the outer cylinder through the honeycomb pores and collected along the conical guide groove to the drain valve; and a high-speed fine desalting stage, where residual salt is completely removed under strong centrifugal force, and simultaneously the high-pressure spray pipe and high-pressure nozzle at the top of the outer cylinder are opened, spraying purified water in the reverse direction at a pressure of 0.5MPa-1MPa to wash away salt crystals on the surface of the seaweed. The mechanical action of the dispersing rod and centrifugal osmotic desalting are carried out simultaneously, shortening the processing time and improving the desalting efficiency of the wakame seaweed.

[0012] After desalination is completed in this utility model, the drain valve is opened to discharge the high-salt wastewater, and the cleaning mode of the spray pipe is started. The spray water is filtered through the outer cylinder → drain valve → high-pressure spray pipe → filter box and then flows back to the inner cylinder for reuse. The cleaning water is reused through filtration, which improves the water saving rate of the device and avoids excessive waste of water resources.

[0013] In this invention, the counterweight block at the top of the sealing cover is dynamically balanced and moves freely along the slide. The position of the counterweight is automatically adjusted by centrifugal force to avoid material displacement caused by vibration during high-speed rotation. It automatically compensates for vibration caused by uneven material distribution and ensures stable high-speed operation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a dispersing and desalting device for processing wakame seaweed. It is characterized by comprising an outer cylinder 1, an inner cylinder 2, and a turntable 3. The outer cylinder 1 is a closed cylinder with a removable sealing cap 4 at its top and a conical guide groove 5 connected to its bottom. The inner cylinder 2 and the turntable 3 are disposed inside the outer cylinder 1. The inner cylinder 2 is also a cylindrical perforated roller, coaxial with the outer cylinder 1. The bottom of the inner cylinder 2 is sealed, and the top is open. Honeycomb holes 6 are evenly distributed on the inner wall of the inner cylinder 2, and a spiral guide rail 7 is provided on its inner wall. The turntable 3 is installed at the bottom of the inner cylinder 2 and is protected by a water-repellent cover 8 connected to the bottom of the inner cylinder 2.

[0023] Using the above scheme: In this utility model, the user can open the sealing cover 4 of the outer cylinder 1, put the salted wakame seaweed into the inner cylinder 2, and close the sealing cover 4. The rotation of the inner cylinder 2 can be divided into three stages: Low-speed dispersing stage: The dispersing rod 9 rotates with the inner cylinder 2, using the collision, friction, and axial thrust generated by the spiral arrangement of the rod and the seaweed to break up the clumps and initially separate the salt particles; Medium-speed desalination stage: Centrifugal force makes the seaweed adhere tightly to the wall of the inner cylinder 2, and the osmotic pressure difference between the inside and outside of the cells accelerates the salt precipitation. The brine is thrown into the outer cylinder 1 through the honeycomb holes 6 and collected along the conical guide groove 5 to the drain valve 13; High-speed fine desalination stage: The residual salt is completely removed under strong centrifugal force. At the same time, the high-pressure spray pipe 15 and high-pressure nozzle 17 at the top of the outer cylinder 1 are opened to spray purified water in the reverse direction at a pressure of 0.5MPa-1MPa to wash away the salt crystals on the surface of the seaweed. The mechanical action of the dispersing rod 9 and the centrifugal osmotic desalination are carried out simultaneously, shortening the processing time and improving the desalination efficiency of the wakame seaweed.

[0024] Multiple dispersing rods 9 are fixed on the spiral guide rail 7. The dispersing rods 9 are fixed at an angle of 20°-30° to the inner cylinder 2 wall. The dispersing rods 9 follow the spiral guide rail 7 in a spiral step arrangement.

[0025] Using the above scheme: the angle between the dispersing rod 9 and the inner cylinder 2 helps to improve the efficiency of dispersing wakame seaweed.

[0026] A connecting flange 10 is installed at the bottom of the turntable 3. A motor 11 and an axial machine 12 are installed inside the connecting flange 10. The axial machine 12 is connected to the turntable 3 through the connecting flange 10.

[0027] A drain valve 13 is provided at the bottom outlet of the conical guide channel 5. A valve switch 14 is provided on the drain valve 13. A high-pressure spray pipe 15 is provided at the bottom of the drain valve 13. A filter box 16 is provided on the outer surface of the outer cylinder 1. The high-pressure spray pipe 15 passes through the filter box 16, and its tail faces the top of the inner cylinder 2. A high-pressure nozzle 17 is provided at the tail of the high-pressure spray pipe 15. The high-pressure nozzle 17 is detachable and adjustable.

[0028] Using the above solution: After desalination is completed in this utility model, the drain valve 13 is opened to discharge the high-salt wastewater, and the cleaning mode of the spray pipe is started. The spray water is filtered through the outer cylinder 1 → drain valve 13 → high-pressure spray pipe 15 → filter box 16 and then flows back to the inner cylinder 2 for reuse. The cleaning water is reused through filtration, which improves the water saving rate of the device and avoids excessive waste of water resources.

[0029] The sealing cover 4 is provided with a pull rod 18 and multiple sliding grooves 19, and a counterweight 20 is provided in the sliding grooves 19.

[0030] In this utility model, the top counterweight 20 of the sealing cover 4 is dynamically balanced and moves freely along the slide groove 19. The position of the counterweight is automatically adjusted by centrifugal force to avoid material displacement caused by vibration during high-speed rotation, and to automatically compensate for vibration caused by uneven material distribution, ensuring stable high-speed operation.

[0031] The dispersing rod 9 is provided with a silicone column 21, and the silicone column 21 is provided with multiple protrusions.

[0032] Using the above solution, the silicone column 21 can significantly reduce the damage rate of wakame seaweed, thereby improving the quality of wakame seaweed.

[0033] The working principle and usage process of this utility model are as follows: The user can open the sealing cover 4 of the outer cylinder 1, put the salted wakame seaweed into the inner cylinder 2, and close the sealing cover 4. The rotation of the inner cylinder 2 can be divided into three stages: low-speed dispersing stage: the dispersing rod 9 rotates with the inner cylinder 2, and the axial thrust generated by the collision, friction and spiral arrangement of the rod and the seaweed breaks up the clumps and initially separates the salt particles; medium-speed desalting stage: centrifugal force makes the seaweed adhere tightly to the wall of the inner cylinder 2, and the osmotic pressure difference between the inside and outside of the cells accelerates the salt precipitation. The brine is thrown into the outer cylinder 1 through the honeycomb holes 6 and collected in the conical guide groove 5 to the drain valve 13; high-speed fine desalting stage: the residual salt is completely removed under strong centrifugal force. At the same time, the high-pressure spray pipe 15 and high-pressure nozzle 17 at the top of the outer cylinder 1 are opened to spray purified water in the reverse direction at a pressure of 0.5MPa-1MPa to wash away the salt crystals on the surface of the seaweed. The mechanical action of the dispersing rod 9 is carried out simultaneously with centrifugal permeation desalination, which shortens the processing time and improves the desalination efficiency of wakame seaweed. After desalination is completed, the drain valve 13 is opened to discharge the high-salt wastewater, and the cleaning mode of the spray pipe is started. The spray water is filtered through the outer cylinder 1 → drain valve 13 → high-pressure spray pipe 15 → filter box 16 and then flows back to the inner cylinder 2 for reuse. The cleaning water is reused through filtration, which improves the water saving rate of the device and avoids excessive waste of water resources.
