Description

Technical Field

[0001] The present invention relates to the technical field of protein enzymolysis, and in particular to a protein enzymolysis reaction system and process. Background Art

[0002] In a protein enzymolysis reaction system, the stirring mechanism is a core component affecting the homogeneity of material mixing and the enzymolysis efficiency. In the prior art, a fixed stirring design is generally adopted. For example, a rigid fan blade or paddle is driven by a motor to rotate unidirectionally (such as the rotating rod and fan blade structure described in the patent publication number CN217265779U). Although such a design can achieve the basic mixing function, it has significant limitations in practical applications: Fixed stirring range: The geometric shape and installation angle of traditional stirring components are fixed, resulting in their action area being limited to a certain fixed spatial level in the reactor. When processing a high-viscosity protein solution, local flow dead zones are easily formed, causing uneven contact between the substrate and enzyme molecules and resulting in a decrease in the enzymolysis reaction rate; Uneven shear force distribution: The shear force field generated by the fixed paddle is distributed in a gradient. The shear force in the area close to the stirring shaft may be too high, causing the free enzyme to denature and inactivate, while the shear force in the edge area is insufficient to fully disperse the aggregated substrate, affecting the mass transfer efficiency; During the enzymolysis reaction process, the substrate concentration, viscosity, and reaction progress continuously change, but the fixed stirrer cannot adjust the action range and intensity in real time. On the other hand, the fixed stirring mode causes part of the energy to be consumed in ineffective turbulence rather than effective mass transfer. Although in recent years, the immobilized enzyme reactor (IMER) technology has improved the enzyme stability through the carrier immobilization strategy, its supporting stirring system is still limited by the fixed structure and cannot solve the problems of diffusion resistance and local concentration gradient in the heterogeneous system. Therefore, developing a new stirring mechanism with a dynamically adjustable stirring range has become the key direction to break through the bottleneck of the existing enzymolysis efficiency.

[0018] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. 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 efforts belong to the scope of protection of the present invention.

[0019] The present invention provides a protein enzymolysis reaction system and process by improvement. The technical solution of the present invention is as follows: As Figures 1 to 9 shown, the embodiment of the present invention provides a protein enzymolysis reaction system, including an enzymolysis tank 1. A homogenization component is arranged inside the enzymolysis tank 1, and a driving component is arranged on the top of the enzymolysis tank 1. The driving component is used to drive the homogenization component to lift and rotate. When the homogenization component moves vertically, the operation range can be increased, so as to achieve the purpose of improving the stirring effect. It also includes; A piston column 301, the top end of the piston column 301 is fixedly connected to a gantry top frame 3, and the gantry top frame 3 is fixedly connected to the top of the enzymolysis tank 1; The homogenization component includes a rotating main pipe 4. The rotating main pipe 4 is movably connected to the top of the enzymolysis tank 1. The piston column 301 is coaxially arranged with the rotating main pipe 4. The bottom end of the piston column 301 is fixedly connected to a plug column 303 adapted to the inner diameter of the rotating main pipe 4, and the plug column 303 is movably connected to the inside of the rotating main pipe 4. A pair of swing plates 9 are rotatably mounted on the outer peripheral wall of the rotating main pipe 4; A material distribution component, the material distribution component is arranged on the inner wall of one end of the enzymolysis tank 1, and a swinging suction unit is arranged between the material distribution component and the rotating main pipe 4; When the driving component controls the rotating main pipe 4 to move in the vertical direction, the swinging suction unit can be made to suck and discharge materials, so as to promote the full mixing of protease and materials.

[0020] Further, as Figures 2 - 5 shown, the material distributing assembly includes an inner ring frame 6 fixedly installed on the inner wall at one end of the enzymolysis tank 1, and a rotating ring plate 601 is rotatably installed on the inner ring frame 6. The cross-section of the rotating ring plate 601 is in a right trapezoidal structure, and a plurality of arc-shaped grooves 602 are formed on the surface of the rotating ring plate 601. The plurality of arc-shaped grooves 602 are distributed in an equidistant annular array; through the above structure, the materials added into the enzymolysis tank 1 will first fall on the rotating ring plate 601, and then be shunted through the plurality of arc-shaped grooves 602 provided. Finally, with the rotation of the rotating ring plate 601, the purpose of uniform feeding is achieved.

[0021] As a further solution of the present invention, the swinging material suction unit includes a pair of communicating short pipes 13 fixedly communicated with the rotating main pipe 4, and a check valve four 131 is fixedly installed on the communicating short pipe 13. The end of the communicating short pipe 13 is rotatably communicated with a square pipe 10. The output direction of the check valve four 131 is from the square pipe 10 to the rotating main pipe 4, and a sealing ring gasket 302 is fixedly installed on the top of the rotating main pipe 4.

[0022] Further, the end of each square pipe 10 is fixedly connected with a communicating cylinder 11, and uniformly distributed filtering through holes 111 are formed on the communicating cylinder 11. On the outer walls on both sides of each square pipe 10, adapter seats 16 are slidably installed along the axial direction. On the bottom outer wall of the rotating ring plate 601, two pairs of inclined fixed pull rods 603 are fixedly installed, and the end of the fixed pull rod 603 is rotatably connected with the adapter seat 16.

[0023] Through the above structure, when the rotating main pipe 4 rotates, it can drive the square pipe 10 to rotate. At the same time, with the cooperation of the provided adapter seats 16 and fixed pull rods 603, the rotating ring plate 601 can be driven to rotate, so as to realize the stirring operation and the material distribution during the feeding process; At the same time, when the rotating main pipe 4 moves vertically under the action of the driving assembly, the provided square pipe 10 can use the end of the fixed pull rod 603 as a leverage point, so that the square pipe 10 swings along the communicating cylinder 11, thereby changing the angle of the communicating cylinder 11 and making the material suction range wider.

[0024] As a further solution of the present invention, extension side rods 14 are fixedly installed on the outer walls on one side of the two square pipes 10, and a transmission rod 141 is fixedly installed at the end of the extension side rod 14. Long circular grooves 901 are formed on the outer walls on one side of the two swing plates 9, and the transmission rod 141 is movably matched with the long circular grooves 901. Uniformly distributed turbulent flow grooves 902 are formed on each swing plate 9.

[0025] Through the above structure, as Figures 5 - 8As shown in the figure, when the square pipe 10 swings along the connecting cylinder 11, it can drive the extension side rod 14 to swing synchronously. Under the combined action of the transmission rod 141 and the long circular groove 901, the elevation angle of the swing plate 9 is adjusted synchronously. Furthermore, while the rotating main pipe 4 drives the swing plate 9 to move up and down, the angle of the swing plate 9 can change in real time, thus ensuring the stirring effect on the material.

[0026] Furthermore, a pair of side pipes 7 are fixedly connected to the rotating main pipe 4. And a check valve three 701 is fixedly installed at one end of the side pipe 7 close to the bottom. The output direction of the check valve three 701 is from the bottom end of the side pipe 7 to the rotating main pipe 4. A stiffening plate 15 is fixedly installed jointly by the two side pipes 7 and the outer wall of the rotating main pipe 4. A pair of branch pipes 8 are fixedly connected to one end of the rotating main pipe 4 close to the top. And a check valve two 801 is fixedly installed on each branch pipe 8. And the output direction of the check valve two 801 faces the rotating main pipe 4. Through the above structure, when the rotating main pipe 4 moves downward, since the piston column 301 and the plug column 303 are fixedly arranged, therefore, the space at the bottom of the piston column 301 increases. Thus, by using the negative pressure effect, the liquid in the enzymatic hydrolysis tank 1 is extracted through the filtering through holes 111 on the connecting cylinder 11. At the same time, the space at the top of the piston column 301 decreases. Thus, the air above the piston column 301 is pressed into the lower end of the rotating main pipe 4 through the side pipe 7 and the check valve three 701. When the rotating main pipe 4 moves upward, the space at the bottom of the piston column 301 decreases. Thus, the inhaled liquid and air are transported to the subsequent sector plate 12 through the check valve one 402 and are ejected through the tree-shaped diversion groove 121. Thus, by using the cavitation effect, the purpose of improving the homogenization effect is achieved. In addition, the space at the top of the piston column 301 increases. And by using the negative pressure effect, air is re-extracted into the rotating main pipe 4 through the branch pipe 8 and the check valve two 801.

[0027] As a further solution of the present invention, as Figures 3 - 5 shown, the bottom end of the rotating main pipe 4 is fixedly connected to a sector plate 12. And a tree-shaped diversion groove 121 communicating with the rotating main pipe 4 is opened in the sector plate 12. A check valve one 402 is fixedly installed at one end of the rotating main pipe 4 close to the sector plate 12. And the output direction of the check valve one 402 is from the rotating main pipe 4 to the tree-shaped diversion groove 121. Through the above structure, when the rotating main pipe 4 rotates, it can drive the sector plate 12 to rotate, playing an auxiliary stirring role. And the provided tree-shaped diversion groove 121 can re-divert the air and the material, further improving the cavitation effect on the material.

[0028] As a further solution of the present invention, as Figure 1 、 Figure 2 and Figure 6As shown in the figure, the driving assembly includes a pair of electric push rods 2 fixedly installed at the top of the enzymolysis tank 1. The ends of the extension rods of the two electric push rods 2 are jointly fixedly installed with a mounting plate 201. The mounting plate 201 is rotatably connected to the rotating main pipe 4 through a bearing. A support outer frame 101 is fixedly installed on the outer peripheral wall of the enzymolysis tank 1. One end of the outer peripheral wall of the enzymolysis tank 1 near the top is fixedly communicated with a feed pipe 103. The bottom end of the enzymolysis tank 1 is fixedly communicated with a valve-equipped discharge pipe 102. After the protein enzymolysis is completed, the valve on the valve-equipped discharge pipe 102 can be opened for discharging operations.

[0029] Furthermore, a driven bevel gear 401 is fixedly installed on the outer peripheral wall of the rotating main pipe 4. A driving motor 5 is fixedly installed on the mounting plate 201. A driving bevel gear 501 is fixedly installed on the output shaft of the driving motor 5. The driving bevel gear 501 and the driven bevel gear 401 are meshed with each other.

[0030] With the above structure, by using the provided electric push rod 2, it can cooperate with the mounting plate 201 to drive the rotating main pipe 4 to move vertically. At the same time, when the driving motor 5 is controlled to start, through the transmission of the driving bevel gear 501 and the driven bevel gear 401, the rotating main pipe 4 can be driven to rotate for stirring operations.

[0031] The specific working method is as follows: During use, the driving motor 5 is controlled to start. Through the transmission of the driving bevel gear 501 and the driven bevel gear 401, the rotating main pipe 4 is driven to rotate. When the rotating main pipe 4 rotates, it can drive the square pipe 10 to rotate. At the same time, in cooperation with the provided adapter seat 16 and fixed pull rod 603, the rotating ring plate 601 can be driven to rotate. The materials added into the enzymolysis tank 1 will first fall on the rotating ring plate 601, and then be shunted through the provided multiple arc-shaped grooves 602. Finally, in cooperation with the rotation of the rotating ring plate 601, the purpose of uniform feeding can be achieved. When the rotating main pipe 4 moves vertically under the action of the driving assembly, the provided square pipe 10 can use the end of the fixed pull rod 603 as a leverage point, causing the square pipe 10 to swing along the connecting cylinder 11, thereby changing the angle of the connecting cylinder 11 and making the material suction range wider. When the square pipe 10 swings along the connecting cylinder 11, it can synchronously drive the extension side rod 14 to swing. And under the combined action of the transmission rod 141 and the long circular groove 901, the elevation angle of the swing plate 9 is synchronously adjusted. Furthermore, when the rotating main pipe 4 drives the swing plate 9 to move up and down, the angle of the swing plate 9 can change in real time, thus ensuring the stirring effect on the materials. When the rotating main pipe 4 moves downward, since the piston column 301 and the plug column 303 are fixedly arranged, the space at the bottom of the piston column 301 increases. Thus, by utilizing the negative pressure effect, the liquid in the enzymatic hydrolysis tank 1 is extracted through the filtering through holes 111 on the communicating cylinder 11. At the same time, the space at the top of the piston column 301 decreases, so that the air above the piston column 301 is pressed into the lower end of the rotating main pipe 4 through the side pipe 7 and the check valve three 701. When the rotating main pipe 4 moves upward, the space at the bottom of the piston column 301 decreases, so that the inhaled liquid and air are transported to the subsequent sector plate 12 through the check valve one 402 and bulge out through the tree-shaped diversion groove 121, thereby utilizing the cavitation effect to achieve the purpose of improving the homogenization effect. In addition, the space at the top of the piston column 301 increases, and by utilizing the negative pressure effect, air is re-extracted into the rotating main pipe 4 through the branch pipe 8 and the check valve two 801. The above operations can effectively homogenize the material. After the protein enzymatic hydrolysis is completed, the valve on the valve-equipped discharge pipe 102 can be opened for discharging operations.
