Description

Technical Field

[0001] The present invention relates to the technical field of separation equipment, and particularly to a biological active peptide separation system and method for Jinhua ham source. Background Art

[0002] Jinhua ham is a famous traditional meat product in China with a very long history and is world-renowned for its outstanding sensory characteristics. The traditional production process has complex steps and a long time-consuming process, going through stages such as low-temperature salting, medium-temperature dehydration, high-temperature ripening, and stacking after-ripening.

[0003] Among them, dry-cured ham produces abundant biological active peptides due to the degradation of proteins by endogenous enzymes during the long fermentation process. In order to separate these abundant biological active peptides, different separation methods are mostly used, including ultrafiltration membrane separation and gel filtration chromatography, etc. When using ultrafiltration membrane to separate Jinhua ham raw materials, pollutants or sediments may accumulate on the membrane surface, resulting in a decline in separation effect. And during the separation process of the ultrafiltration membrane, since the position of the ultrafiltration membrane is mostly fixed and cannot swing by a certain amplitude, this will cause most of the raw materials to pile up or block on the ultrafiltration membrane, which greatly affects the separation effect of the ultrafiltration membrane.

In the present invention, the raw materials to be separated are placed inside the separation box. The lower pressing plate is driven to move inside the separation box through the hydraulic cylinder. Through the pressure generated during downward pressing, the raw materials on the ultrafiltration membrane are rapidly separated. When the lower pressing plate descends, it will synchronously drive two single-sided toothed plates to descend. The two single-sided toothed plates cooperate with the first gear and the second gear respectively. The first gear and the second gear are used to drive the bumps on the two rotating shafts to rotate respectively. Then, the two bumps are indirectly matched with the two pressure-receiving convex plates, and the elastic force of the return spring is utilized, so that the ultrafiltration membrane inside the separation box is in a reciprocating pulling state, improving the separation effect of the ultrafiltration membrane; 2. In the present invention, when the single-sided toothed plate descends, it will synchronously drive the connecting rod to move downward. The double-sided toothed plate on the connecting rod will cooperate with the left gear and the right gear.

Rotating shafts 10 are rotatably installed on both support frames 9. A first gear 11 and a second gear 12 are respectively fixedly installed on the two rotating shafts 10.

The two single-sided toothed plates 8 are respectively engaged with the first gear 11 and the second gear 12. Both ends of the ultrafiltration membrane 3 are fixedly connected to the lower end surfaces of the two pressure-receiving convex plates 15. The convex blocks 13 on the two rotating shafts 10 are set at different angles, so that the two pressure-receiving convex plates 15 are not on the same horizontal plane.

[0020] In this embodiment, the raw materials to be separated are placed inside the separation box 1. The hydraulic cylinder 6 is used to drive the lower pressing plate 7 to move inside the separation box 1. Through the pressure generated during pressing, the raw materials on the ultrafiltration membrane 3 are quickly separated. When the lower pressing plate 7 descends, it will synchronously drive the two single-sided toothed plates 8 to descend. By the cooperation of the two single-sided toothed plates 8 with the first gear 11 and the second gear 12 respectively, the first gear 11 and the second gear 12 are used to drive the convex blocks 13 on the two rotating shafts 10 to rotate respectively.

Then, by using the cooperation of the threaded rod 22 and the threaded hole 24, the convex block 13 will adjust its own position through the limitation of the installation groove 21, thereby adjusting the pulling amplitude of the ultrafiltration membrane 3 to achieve the required separation effect.

[0023] An auxiliary assembly is arranged inside the separation box 1. The separation effect of the ultrafiltration membrane 3 is improved through the auxiliary assembly. The auxiliary assembly includes two auxiliary shafts 25 rotatably installed on the separation box 1. Separation blades 26 are fixedly installed on both of the two auxiliary shafts 25.

The auxiliary shafts 25 are rotatably installed in a positioned manner with the separation box 1 to ensure that the auxiliary shafts 25 will not shift in position.

[0024] In this embodiment, when the single-sided tooth plate 8 descends, it will synchronously drive the connecting rod 29 to move downward. The double-sided tooth plate 30 on the connecting rod 29 will cooperate with the left gear 27 and the right gear 28 to drive the two auxiliary shafts 25 to rotate in opposite directions through the left gear 27 and the right gear 28. The separation blades 26 on the auxiliary shafts 25 stir the raw materials on the ultrafiltration membrane 3, enabling more efficient separation during the raw material filtration process.

[0025] Positioning shafts 31 are fixedly installed on both the left gear 27 and the right gear 28. A drive rod 32 is rotatably installed on the positioning shaft 31.

[0027] A method for separating bioactive peptides from Jinhua ham source, based on a bioactive peptide separation system from Jinhua ham source in the above text, includes the following steps: S1. Put the raw materials to be separated into the interior of the separation box 1. Drive the lower pressing plate 7 to move in the separation box 1 through the hydraulic cylinder 6. Through the pressure generated during downward pressing, the raw materials on the ultrafiltration membrane 3 are rapidly separated. When the lower pressing plate 7 descends, it will synchronously drive the two single-sided toothed plates 8 to descend. By the cooperation of the two single-sided toothed plates 8 with the first gear 11 and the second gear 12 respectively, the first gear 11 and the second gear 12 are used to drive the bumps 13 on the two rotating shafts 10 to rotate. Then, by the indirect cooperation of the two bumps 13 with the two pressure-receiving convex plates 15, and the elastic force of the return spring 16, the ultrafiltration membrane 3 in the separation box 1 is in a state of reciprocating pulling, improving the separation effect of the ultrafiltration membrane 3. S2. When the single-sided toothed plate 8 descends, it will synchronously drive the connecting rod 29 to move downward.

The separation blades 26 on the auxiliary shafts 25 stir the raw materials on the ultrafiltration membrane 3. S3. When the left gear 27 and the right gear 28 rotate, the positioning shaft 31 will drive the drive rod 32 to rotate around the positioning shaft 31. Then, by the cooperation of the drive rod 32 and the U-shaped push rod, and the limitation of the stabilizing block 33, the vibrating plate 36 on the U-shaped push rod is used to slightly knock on the ultrafiltration membrane 3, enhancing the separation effect of the ultrafiltration membrane 3. S4. When it is necessary to adjust the pulling amplitude of the ultrafiltration membrane 3, the motor 19 is used to drive the disk gear 20 to rotate. Through the cooperation of the disk gear 20 and the bevel gear 23, the bevel gear 23 will drive the threaded rod 22 to rotate. Then, by using the cooperation of the threaded rod 22 and the threaded hole 24, the convex block 13 can adjust its own position through the limitation of the installation groove 21.

[0028] Working principle: During use, the raw materials to be separated are placed inside the separation box 1. The hydraulic cylinder 6 is used to drive the lower pressing plate 7 to move inside the separation box 1. Through the pressure generated during downward pressing, the raw materials on the ultrafiltration membrane 3 are quickly separated. When the lower pressing plate 7 descends, it will synchronously drive the two single-sided toothed plates 8 to descend. Through the cooperation of the two single-sided toothed plates 8 with the first gear 11 and the second gear 12 respectively, the convex blocks 13 on the two rotating shafts 10 are driven to rotate by the first gear 11 and the second gear 12 respectively. Then, by using the two convex blocks 13 to indirectly cooperate with the two pressure-receiving convex plates 15 and the elastic force of the return spring 16, the ultrafiltration membrane 3 inside the separation box 1 is in a state of reciprocating pulling, improving the separation effect of the ultrafiltration membrane 3. When the single-sided toothed plate 8 descends, it will synchronously drive the connecting rod 29 to move downward. The double-sided toothed plate 30 on the connecting rod 29 will cooperate with the left gear 27 and the right gear 28, and the left gear 27 and the right gear 28 are used to drive the two auxiliary shafts 25 to rotate in opposite directions. The separation blades 26 on the auxiliary shafts 25 stir the raw materials on the ultrafiltration membrane 3. When the left gear 27 and the right gear 28 rotate, they will drive the driving rod 32 to rotate around the positioning shaft 31 through the positioning shaft 31. Then, by using the cooperation of the driving rod 32 and the U-shaped push plate 34 and the limitation of the stabilizing block 33, the vibrating plate 36 on the U-shaped push plate 34 is used to slightly knock the ultrafiltration membrane 3, enhancing the separation effect of the ultrafiltration membrane 3. When it is necessary to adjust the pulling amplitude of the ultrafiltration membrane 3, the motor 19 is used to drive the disk gear 20 to rotate. Through the cooperation of the disk gear 20 and the bevel gear 23, the bevel gear 23 will drive the threaded rod 22 to rotate. Then, by using the cooperation of the threaded rod 22 and the threaded hole 24, the convex block 13 can adjust its own position through the limitation of the installation groove 21.

The elastic force of the return spring (16) is then used to make the ultrafiltration membrane (3) in the separation box (1) be in a reciprocating pulling state, thereby improving the separation effect of the ultrafiltration membrane (3); S2. When the single-sided toothed plate (8) descends, it will synchronously drive the connecting rod (29) to move downward, and the double-sided toothed plate (30) on the connecting rod (29) will cooperate with the left gear (27) and the right gear (28), and drive the two auxiliary shafts (25) to rotate in opposite directions through the left gear (27) and the right gear (28), and the separation blades (26) on the auxiliary shafts (25) stir the raw materials on the ultrafiltration membrane (3); S3. When the left gear (27) and the right gear (28) rotate, the positioning shaft (31) drives the driving rod (32) to rotate around the positioning shaft (31), and then the driving rod (32) cooperates with the U-shaped push plate (34) and the position limit of the stabilizing block (33), and the vibration plate (36) on the U-shaped push plate (34) is used to lightly knock the ultrafiltration membrane (3), thereby enhancing the separation effect of the ultrafiltration membrane (3); S4. When the pulling amplitude of the ultrafiltration membrane (3) needs to be adjusted, the motor (19) drives the disc teeth (20) to rotate, and the disc teeth (20) cooperate with the bevel gear (23), and the bevel gear (23) drives the threaded rod (22) to rotate. Then, the threaded rod (22) cooperates with the threaded hole (24), and the protrusion (13) adjusts its position through the limit of the installation groove (21).
