Description

Technical Field

[0001] This invention relates to the field of protein peptide separation technology, and in particular to a centrifuge apparatus for preparing marine fish protein peptides. Background Technology

[0002] As people's living standards gradually improve, more and more people are eating various kinds of seafood, especially deep-sea fish, which are rich in nutrients and can replenish the body's required nutrients. Among them, fish collagen peptides are high-molecular-weight functional proteins that can repair damaged cells, making the skin firmer and more elastic, improving facial wrinkles, and slowing down skin aging, as well as fading spots and whitening the skin.

[0003] The extraction of fish collagen peptides primarily uses fish scales and skin as raw materials. Compared to freshwater fish, deep-sea fish pose less risk of animal diseases and artificially bred drug residues, making them safer to use. They also contain unique antifreeze proteins, and although expensive, they are widely accepted by women worldwide. After processing, the skin and flesh of deep-sea fish are separated and then placed in a centrifuge. Through reaction with a solution within the centrifuge, the protein peptide molecules are separated from the skin and scales, thus obtaining the stock solution. Existing centrifuge equipment has limited functionality, and its separation effect on protein peptides is not significant. The reasons for this are threefold: First, fish skin and scales are lighter than fish meat, making them less prone to movement during centrifugation. They tend to adhere to the inner wall of the filter cartridge under centrifugal force, significantly slowing down protein separation. Second, deep-sea fish skin is relatively large, necessitating a cutting process before centrifugation. This cutting process wastes some protein and makes the skin and scales susceptible to contamination. Third, the scales adhere to the skin and cannot be detached, further reducing the separation speed. These factors directly reduce the separation speed of centrifuge equipment, clearly rendering existing equipment inadequate for the required separation rate. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a centrifugation device for preparing marine fish protein peptides. It features a reasonable structural design and convenient operation, effectively solving the problem of fish skin and scales floating up and down within the filter cylinder during centrifugation. Without requiring a separate cutting process, the scales and skin can be separated during centrifugation, and the skin can be cut, thus greatly accelerating the separation speed of fish collagen peptides and solving the problems existing in practical use.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A centrifuge apparatus for preparing marine fish protein peptides includes a tank and a support frame disposed at the lower part of the tank. The lower sidewall of the tank converges inward to form a funnel shape. A filter cylinder is vertically disposed coaxially within the tank. The filter cylinder is connected to a drive mechanism disposed at the bottom of the tank. An annular limiting seat is horizontally disposed along its circumference on the upper part of the inner wall of the tank. A limiting member abuts against the outer wall of the filter cylinder on the inner wall of the annular limiting seat. An annular support seat abuts against the inner wall of the tank on the surface of the annular limiting seat. A cutting component disposed within the filter cylinder has its upper end secured to the annular support seat by the support member. A cover plate is disposed at the opening at the top of the tank.

[0010] Optionally, the cutting edge of the spiral blade is serrated.

[0011] Optionally, a number of folded blades are provided on the surface of the stirring plate along its circumference.

[0032] like Figure 1-8 As shown, a centrifuge device for preparing marine fish protein peptides includes a tank 1 and a support frame 2 disposed at the lower part of the tank 1. The lower side wall of the tank 1 converges inward to form a funnel shape. A filter cylinder 3 is vertically disposed coaxially inside the tank 1. The filter cylinder 3 is connected to a drive mechanism disposed at the bottom of the tank 1. An annular limiting seat 4 is horizontally disposed along its circumference on the upper part of the inner wall of the tank 1. A limiting member abutting against the outer wall of the filter cylinder 3 is disposed on the inner wall of the annular limiting seat 4. An annular support seat 5 abutting against the inner wall of the tank 1 is disposed on the surface of the annular limiting seat 4. A cutting piece disposed inside the filter cylinder 3 has its upper end clamped to the annular support seat 5 by the support member. A cover plate 6 is disposed at the opening at the top of the tank 1. A retaining seat 7 abutting against the support member is disposed at the bottom of the cover plate 6. A drain pipe 8 is connected to the bottom of the tank 1.

[0033] Optionally, the drive mechanism includes a cavity 9 located at the center of the bottom of the tank 1, a drive motor 10 located at the center of the bottom of the tank 1, whose output shaft passes vertically upward through the bottom of the tank 1 and is connected to a rotating disk 11 that is movably engaged in the cavity 9, and a rotating gear 12 is provided at the center of the surface of the rotating disk 11; a linkage seat 13 is provided at the bottom of the filter cylinder 3, and a toothed groove 14 that cooperates with the rotating gear 12 is provided at the bottom of the linkage seat 13.

[0034] Optionally, the limiting member includes an annular groove 15 formed on the inner wall of the annular limiting seat 4 along the circumferential direction, and a plurality of vertically arranged limiting rollers 16 are evenly spaced along the circumferential direction in the annular groove 15, and each limiting roller 16 is movably abutting against the outer wall of the filter cylinder 3.

[0035] Optionally, the slitting component includes a decomposition block 17 arranged coaxially with the filter cylinder 3, a conical block 18 arranged coaxially at the top of the decomposition block 17, a spiral blade 19 on the outer wall of the decomposition block 17, a plurality of recesses 20 on the inner wall of the filter cylinder 3 corresponding to the position of the spiral blade 19, and a clamping block 21 vertically arranged at the center of the top of the conical block 18, which abuts against the bottom of the cover plate 6; a cavity 22 vertically arranged in the center of the conical block 18, which communicates with the decomposition block 17, and a cylinder 23 arranged in the cavity 22, the piston rod of which moves downward through the decomposition block 17 and connects to the stirring plate 24 arranged in the filter cylinder 3.

[0036] Optionally, the spiral blade 19 has a serrated edge. This allows for better rubbing of the fish skin or scales during the cutting process, increasing resistance and enabling faster separation of the skin and scales.

[0037] Optionally, a plurality of folded blades 25 are provided on the surface of the stirring plate 24 along its circumference. When the piston rod of the cylinder 23 retracts, it drives the stirring plate 24 to move upward, further stirring the fish skin and scales as they float up and down until they come into contact with the bottom of the decomposition block 17. The fish skin that falls between the decomposition block 17 and the stirring plate 24 is then further shredded.

[0038] Optionally, the support includes a fixing ring 26 snapped onto the annular support base 5, a fixing groove 27 formed on the outer wall of the clamping block 21 at the position corresponding to the fixing ring 26 along its circumferential direction, a support ring 28 fixedly sleeved on the fixing groove 27, and connected to the inner wall of the fixing ring 26 by a plurality of connecting rods 29 provided on its outer side wall, a plurality of positioning posts 34 provided at the bottom of the fixing ring 26 along its circumferential direction, and positioning grooves 35 respectively provided on the annular support base 5 at the position corresponding to each positioning post 34.

[0039] Optionally, a guide shell 30 is provided at the bottom of the fixing ring 26 and sleeved on the clamping block 21. The upper part of the outer side wall of the guide shell 30 is connected to the inner wall of the fixing ring 26 through an arc plate 31, and the upper part of its inner side wall is connected to the support ring 28. Several leakage holes 32 are provided at the bottom of the guide shell 30 along its circumference. This facilitates the insertion of fish skin with scales into the filter cylinder 3 from the opening of the tank 1, and better guides the fish, preventing it from directly entering the tank 1.

[0040] Optionally, the filter cylinder 3 includes a plurality of filter holes 33 disposed on its lower side wall, each of the filter holes 33 being disposed below the decomposition block 17.

[0041] Optionally, the support frame 2 includes a retaining ring 201 disposed on the outer wall of the tank body 1, and a plurality of support legs 202 are evenly disposed at the bottom of the retaining ring 201 along its circumferential direction, and the bottom of each support leg 202 is fixedly disposed on the base 203.

[0042] Before use, a solution needs to be injected into the tank. It is important to note that the solution level in tank 1 should not exceed the decomposition block 17. When in use, first start the drive motor 10. The output shaft of the drive motor 10 rotates via the drive disc 11, which in turn rotates the linkage seat 13 via the rotating gear 12, thus rotating the filter cylinder 3. The upper part of the filter cylinder 3 is limited by limiting components, ensuring radial rotation of the filter cylinder 3 and assisting in radial rotation via various limiting rollers 16. The cutting component is fixed in place by the support components. Then, open the cover plate 6 and insert fish skin with scales into the opening of tank 1. The fish skin enters the filter cylinder 3 through the leakage holes 32 of the guide shell 30, slides downwards under the guidance of the conical block 18, and slides between the decomposition block 17 and the filter cylinder 3. As the filter cylinder 3 rotates, the spiral blade 19 cuts the fish skin, while the other side is initially fixed by various concave points 20, increasing resistance and separating the fish scales from the fish skin. The separated fish scales and skin enter the bottom of the filter cylinder 3 and adhere to the inner wall of the filter cylinder 3 as it rotates. At this time, the cylinder 23 is activated to reciprocate, and the stirring plate 24 moves up and down, thus agitating the solution inside the filter cylinder 3, creating turbulence. This stirs up the fish scales and skin, and as they float, they are further separated by the folding blade 25, resulting in finer separation. After the reaction is complete, the valve on the drain pipe 8 is opened to collect the original liquid. Its reasonable structural design and convenient operation effectively solve the problem of fish skin and scales floating up and down in the filter cylinder during centrifugation. It eliminates the need for a separate separation process, allowing for the separation of fish scales and skin during centrifugation and the further separation of the skin, thus greatly accelerating the separation speed of fish collagen peptides and solving problems encountered in practical use.
