Description

Technical Field

[0001] The present invention relates to the field of oyster peptide decolorization, and more specifically, to a decolorization device and method for extracting oyster peptides. Background Art

[0002] Oyster peptides are made by applying peptide molecular biotechnology to the oyster processing process and enzymatically hydrolyzing them into oyster peptides. The small molecule oligopeptides formed by this production method completely retain the original vitamins, trace elements, taurine and other nutrients in oysters, making the oysters rich in nucleic acids be absorbed faster by the human body than single amino acids or proteins, and are more easily absorbed by the body. They have more important biological activities in human metabolism and can effectively increase the serum testosterone level in men. They have higher biological potency and more important physiological functions than ordinary oyster products. The extract obtained by rough processing has a certain color and needs to be decolorized.

[0003] During decolorization, first, an enzymatic hydrolysate containing oyster peptides is obtained through an enzymatic hydrolysis process, and then a decolorizing agent is fully mixed with the enzymatic hydrolysate. Subsequently, the filtered enzymatic hydrolysate is decolorized; during the decolorization process, solids are likely to block the mesh holes during filtration, resulting in unsmooth filtration; at the same time, the filter screen is difficult to clean conveniently.

[0004] In view of this, in view of the above-mentioned deficiencies, the present invention is based on the filtration in the prior art and has been improved and optimized, and a decolorization device and method for extracting oyster peptides have been developed. Summary of the Invention

Detailed implementation manner

[0080] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0081] As Figures 1 to 11 shown, a decolorization device for extracting oyster peptides includes: a decolorization barrel 1; further includes: a top cover 101 provided at the top end of the decolorization barrel 1; a conical bottom plate 102 provided at the bottom end of the decolorization barrel 1; a feeding part provided on the decolorization barrel 1; a stirring part provided inside the decolorization barrel 1 to stir the extraction liquid; a filtering part provided inside the decolorization barrel 1 and at the bottom of the stirring part; a support circular plate 301 provided between the stirring part and the filtering part to isolate the space between the stirring part and the filtering part; a sealing connection part provided on the support circular plate 301 to ensure the connection or closure between the stirring part and the filtering part; a scraping part provided inside the filtering part to ensure the filtering effect of the filtering part; a cleaning part connected to the sealing connection part to clean the filtering part; a discharge part 5 provided on the conical bottom plate 102 to separate solid impurities; the sealing connection part includes: a rubber ring 306 sleeved at the central through hole of the support circular plate 301; a sealing plug 307 provided on the rubber ring 306; two electromagnets 305 symmetrically provided on the support circular plate 301; a first limit groove 308 opened on the sealing plug 307 to cooperate with the scraping part for connection.

[0082] In the embodiment of the present invention, by providing a stirring part, the enzymolysis liquid and the decolorizing agent are fully mixed during decolorization, and the decolorization is more complete; at the same time, a filtering part is provided to filter the solution after decolorization is completed, so as to separate solid and liquid. By providing a sealed connection part that is cooperatively connected with the stirring part and the scraping part, when filtering, the scraping part automatically scrapes the filter cylinder 6 repeatedly to prevent solids from clogging the mesh of the filter cylinder 6, improving the filtering efficiency; by providing a cleaning part, the outside of the filter cylinder 6 is regularly cleaned to ensure the cleanliness of the filter cylinder 6.

[0083] As Figures 1 to 11 shown, the stirring part includes: a first motor 201, arranged at the center of the top cover 101; a first rotating shaft 202, one end of which is connected to the output end of the first motor 201; a plurality of groups of stirring rods 203, and the plurality of groups of stirring rods 203 are arranged in an array on the first rotating shaft 202; a first square groove 204, opened at one end of the first rotating shaft 202 away from the first motor 201.

[0084] In the embodiment of the present invention, the prepared enzymolysis liquid containing oyster peptides is put into the stirring part in the decolorization barrel 1 from the liquid inlet pipe 104, and at the same time, the prepared decolorizing agent is put into the stirring part in the decolorization barrel 1 from the feed pipe 105; at this time, the sealing plug 307 is tightly connected to the rubber ring 306 to ensure that the liquid will not leak into the filtering part; then the first motor 201 is started to drive the first rotating shaft 202 to rotate, thereby driving the stirring rods 203 to rotate, stirring the liquid, so that the enzymolysis liquid and the decolorizing agent are fully mixed.

[0085] As Figures 4 to 6 shown, the filtering part includes: a second limiting groove 601, opened on the conical bottom plate 102; a filter cylinder 6, one end of which is placed in the second limiting groove 601; a limiting ring 602, arranged at the bottom end of the supporting circular plate 301 and in limiting connection with the top end of the filter cylinder 6.

[0086] In the embodiment of the present invention, the filter cylinder 6 is placed in the second limiting groove 601, and at the same time, the top end of the filter cylinder 6 is limited by the limiting ring 602, so that when the filter cylinder 6 rotates, it will always be in the second limiting groove 601, so that the filter cylinder 6 rotates around its own axis, avoiding vibration during rotation.

[0087] As Figures 4 to 10As shown in the figure, the scraping part includes: a second limiting square block 403 that slides within the first limiting groove 308; a second limiting square rod 402, one end of which is connected to the second limiting square block 403 and is in limiting sliding connection with the first limiting groove 308; a support block disposed on the conical bottom plate 102; a second rotating shaft 401, one end of which is connected to the other end of the second limiting square rod 402 and the other end of which is placed on the support block; a plurality of sets of movable connecting shafts, and the plurality of sets of movable connecting shafts are connected to the second rotating shaft 401 through movable parts; and a scraping plate 405 that is hinged to the other end of the movable connecting shaft.

[0088] As Figures 4 to 10 As shown in the figure, the sealing connection part further includes: a magnetic disk 304 disposed on the sealing plug 307 and in mating connection with the electromagnet 305; a connecting square rod 302 disposed on the magnetic disk 304 and in mating connection with the first rotating shaft 202; and a connecting square cone 303 disposed at the other end of the connecting square rod 302 to be in mating connection with the first square groove 204.

[0089] In the embodiment of the present invention, after the enzymatic hydrolysate and the decolorizing agent are fully mixed, the first gear of the electromagnet 305 is started. The electromagnet 305 is energized to repel the magnetic disk 304, thereby driving the magnetic disk 304 to move upward. The magnetic disk 304 drives the sealing plug 307 to move upward, so that the sealing plug 307 and the rubber ring 306 are separated, and the liquid will flow from the through hole in the middle of the support circular plate 301 into the filter cartridge 6 in the filtering part; after the liquid flows into the filter cartridge 6, it will pass through the filter cartridge 6 and flow out from the liquid outlet pipe 106, which is the enzymatic hydrolysate containing oyster peptides after decolorization, while the solid is either adhered to the filter cartridge 6 or precipitated at the bottom end of the conical bottom plate 102; at the same time, the magnetic disk 304 moves upward, driving the connecting square rod 302 and the connecting square cone 303 to move upward into the first square groove 204, so that the connecting square rod 302 and the connecting square cone 303 follow the first rotating shaft 202 to rotate. The connecting square rod 302 drives the second rotating shaft 401 to rotate through the magnetic disk 304, the sealing plug 307 and the first limiting groove 308, and then drives the scraping plate 405 to rotate through the movable connecting rod 404 to repeatedly scrape the inner wall of the filter cartridge 6; to prevent solids from adhering to the inner wall of the filter cartridge 6 during filtration and affecting the filtration efficiency.

[0090] Among them, a support block (not shown in the figure) is provided and connected to the conical bottom plate 102 to support the bottom end of the second rotating shaft 401 and prevent unstable rotation.

[0091] As Figures 4 to 10As shown, the movable member includes: a first rotating groove 406, formed on the second rotating shaft 401 and hinged to one end of the second rotating shaft 401; a stop block 407, disposed on the movable connecting shaft; and a limiting spring 408, with one end connected to the inside of the first rotating groove 406 and the other end connected to the stop block 407.

[0092] In an embodiment of the present invention, at the hinge joint between the movable connecting shaft and the second rotating shaft 401, the movable connecting shaft is inclined upward at a certain angle relative to the horizontal plane. Thus, under the action of gravity, the movable connecting shaft drives the scraping plate 405 to move outward. Meanwhile, in cooperation with the elastic force of the provided limiting spring 408 acting on the movable connecting shaft outward, the scraping plate 405 can tightly abut against the inner wall of the filter screen, enabling the scraping plate 405 to effectively scrape off the impurities adhering to the filter screen.

[0093] As Figures 4 to 10 As shown, the cleaning part includes: a water inlet pipe 107, disposed on the outer surface of the decolorizing barrel 1; a water passing groove 309, formed on the supporting circular plate 301 and cooperatively connected to the water inlet pipe 107; a connecting water pipe 310, disposed at the bottom end of the supporting circular plate 301 and cooperatively connected to the water passing groove 309; and a plurality of groups of high-pressure nozzles 311, sequentially disposed on the connecting water pipe 310 and facing the filter cylinder 6.

[0094] In an embodiment of the present invention, when the filter cartridge 6 is cleaned under high pressure, high-pressure water is connected through the water inlet pipe 107, and the high-pressure water is sprayed out from the high-pressure nozzle 311 through the water trough 309 and the connecting water pipe 310, so as to spray on the outer surface of the filter cartridge 6; by rotating the filter cartridge 6, the whole filter cartridge 6 is cleaned; by rotating the sleeve, by starting the second gear of the electromagnet 305, the magnetic disc 304 is driven to move upward continuously, so as to drive the sealing plug 307 to move upward. Since the second limiting block 403 has moved to one end of the first limiting groove 308 along the first limiting groove 308 when the electromagnet 305 is energized in the first gear, when the sealing plug 307 continues to move upward, it will drive the second limiting block 403 to move upward, and then drive the second rotating shaft 401 to move upward through the second limiting square rod 402. When the second rotating shaft 401 moves upward, it will drive the movable connecting rod 404 to rotate at an angle. Since one end of the movable connecting rod 404 close to the second rotating shaft 401 is slightly lower than one end of the scraping plate 405, the scraping plate 405 is driven to move outward. Since the scraping plate 405 has been attached to the inner wall of the filter cartridge 6, under the action of the thrust of the movable connecting rod 404, the scraping plate 405 clamps the filter screen, so as to drive the filter screen to rotate together. When the filter screen rotates, it will always be in the second limiting groove 601, so that the filter cartridge 6 rotates around its own axis, avoiding vibration during rotation. At this time, the high-pressure nozzle 311 cooperates with the rotating filter screen to fully clean the filter cartridge 6.

[0095] As Figure 11 shown, the discharging part 5 includes: a discharging pipe 501 connected to the bottom end of the conical bottom plate 102; a first ball valve 502 arranged inside the discharging pipe 501; a second motor 503 arranged on the discharging pipe 501, and the output end is connected to the first ball valve 502 to control the opening or closing of the first ball valve 502; a second ball valve 504 arranged inside the discharging pipe 501 and located at the bottom end of the first ball valve 502; a third motor 505 arranged on the discharging pipe 501, and the output end is connected to the second ball valve 504 to control the opening or closing of the second ball valve 504.

[0096] In the embodiment of the present invention, the filtered solid will finally settle at the bottom end of the conical bottom plate 102. After a certain amount of solid impurities settle at the bottom end, the second motor 503 is started to drive the first spherical valve 502 to rotate, so that the discharge pipe 501 is communicated. At this time, the solid impurities at the bottom end of the conical bottom plate 102 will move between the first spherical valve 502 and the second spherical valve 504, and only a small amount of liquid comes in with the impurities. After closing the first spherical valve 502, the third motor 505 is started to drive the second spherical valve 504 to rotate, so that the channel of the second spherical valve 504 is opened, so that the impurities between the first spherical valve 502 and the second spherical valve 504 fall to the outside; thus, it is avoided that a large amount of liquid is carried out during direct discharging.

[0097] As Figure 1 shown, the feeding part includes: a feeding pipe 105, which is arranged on the top cover 101 for putting in a decolorizing agent; a liquid inlet pipe 104, which is arranged at one end of the top cover 101 far from the feeding pipe 105 for putting in an enzymolysis solution.

[0098] In the embodiment of the present invention, the decolorizing agent and the enzymolysis solution are put in through the feeding pipe 105 and the liquid inlet pipe 104; at the same time, a triangular support frame 103 is provided to support the decolorizing barrel 1.

[0099] The present invention also provides a decolorizing method applicable to the above-mentioned decolorizing device for extracting oyster peptides, which is characterized in that it includes the following steps:

[0100] S1. Prepare an enzymolysis solution containing oyster peptides, put the enzymolysis solution into the stirring part in the decolorizing barrel 1 from the liquid inlet pipe 104, and at the same time put the prepared decolorizing agent into the stirring part in the decolorizing barrel 1 from the feeding pipe 105;

[0101] S2. Start the first motor 201 to drive the first rotating shaft 202 to rotate, and then drive the stirring rod 203 to rotate, so as to fully mix the enzymolysis solution and the decolorizing agent;

[0102] S3. Let the fully mixed liquid flow into the filtering part, start the electromagnet 305 to drive the magnetic disc 304 to move upward, thereby driving the connecting square rod 302 and the connecting square cone 303 to move upward into the first square groove 204, so that the connecting square rod 302 and the connecting square cone 303 follow the first rotating shaft 202 to rotate. The connecting square rod 302 drives the second rotating shaft 401 to rotate through the magnetic disc 304, the sealing plug 307 and the first limiting groove 308, and then drives the scraping plate 405 to rotate through the movable connecting rod 404, and repeatedly scrapes the inner wall of the filter cylinder 6;

[0103] S4. The decolorized enzymolysis solution flows out from the liquid outlet pipe 106 through the filter cylinder 6, and the filtered solid impurities are separated from the discharging part 5 to complete decolorization.
