Description

Technical Field

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

[0002] In protein enzymatic hydrolysis systems, the stirring mechanism is a core component that influences material mixing homogeneity and hydrolysis efficiency. Existing technologies generally employ fixed stirring designs, such as those using a motor to drive rigid blades or paddles for unidirectional rotation (e.g., the rotating rod and blade structure described in Patent Publication No. CN217265779U). While these designs can achieve basic mixing functions, they have significant limitations in practical applications:

[0003] Fixed stirring range: The fixed geometry and installation angle of traditional stirring components limit their action area to a fixed spatial level within the reactor. When processing high-viscosity protein solutions, localized dead zones are easily formed, resulting in uneven contact between substrate and enzyme molecules, leading to a decrease in the enzymatic reaction rate.

[0004] Uneven shear force distribution: The shear force field generated by the fixed blades is distributed in a gradient. Excessive shear force in the area near the stirring shaft may cause denaturation and inactivation of free enzymes, while insufficient shear force in the edge area cannot fully disperse the aggregated substrate, affecting mass transfer efficiency.

[0005] During enzymatic hydrolysis, substrate concentration, viscosity, and reaction progress continuously change, but fixed agitators are unable to adjust their range and intensity in real time. Furthermore, fixed agitation modes result in some energy being consumed in ineffective turbulence rather than efficient mass transfer. Although recent advances in immobilized enzyme reactors (IMERs) have improved enzyme stability through carrier immobilization strategies, their accompanying agitation systems remain limited by their fixed structure, unable to address the diffusion resistance and local concentration gradients found in heterogeneous systems. Therefore, developing novel agitation mechanisms with dynamically adjustable agitation ranges has become a key approach to addressing the current bottleneck in enzymatic hydrolysis efficiency.

[0041] The present invention provides a protein enzymatic hydrolysis reaction system and process through improvement. The technical solution of the present invention is:

[0042] like Figures 1 to 9 As shown, an embodiment of the present invention provides a protein enzymatic hydrolysis reaction system, including an enzymatic hydrolysis tank 1, wherein a homogenizing component is provided inside the enzymatic hydrolysis tank 1, and a driving component is provided on the top of the enzymatic hydrolysis tank 1, wherein the driving component is used to drive the homogenizing component to move up and down and rotate. When the homogenizing component moves vertically, the operating range can be increased, thereby achieving the purpose of improving the stirring effect, and further comprising;

[0043] The piston column 301, the top of the piston column 301 is fixedly connected to the gantry top frame 3, and the gantry top frame 3 is fixedly connected to the top of the enzymolysis tank 1;

[0044] The homogenizing assembly includes a rotating main pipe 4, which is movably connected to the top of the enzymolysis tank 1. A piston column 301 is coaxially arranged with the rotating main pipe 4, and a plug column 303 adapted to the inner diameter of the rotating main pipe 4 is fixedly connected to the bottom end of the piston column 301. 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.

[0045] The material distribution component is arranged on the inner wall of one end of the enzymatic hydrolysis tank 1, and a swinging material 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 material suction unit can suck and discharge the material to promote the full mixing of the protease and the material.

[0046] Further, such as Figure 2-Figure 5 As shown, the material distribution component includes an inner ring frame 6 fixedly mounted on the inner wall of one end of the enzymolysis tank 1, and a rotating plate 601 is rotatably mounted on the inner ring frame 6, and the cross-section of the rotating plate 601 is a right-angled trapezoidal structure, and a plurality of arc grooves 602 are provided on the surface of the rotating plate 601, and the plurality of arc grooves 602 are distributed in an equidistant annular array; through the above structure, the material added to the enzymolysis tank 1 will first fall on the rotating plate 601, and then be diverted through the plurality of arc grooves 602, and finally, with the rotation of the rotating plate 601, the purpose of uniform feeding can be achieved.

[0047] As a further solution of the present invention, the swinging suction unit includes a pair of connecting short tubes 13 fixedly connected to the rotating main tube 4, and a one-way valve four 131 is fixedly installed on the connecting short tube 13.

The output direction of the one-way valve four 131 is transmitted from the square tube 10 to the rotating main tube 4. A sealing ring gasket 302 is fixedly installed on the top of the rotating main tube 4.

[0048] Furthermore, the end of each square tube 10 is fixedly connected to a connecting tube 11, and the connecting tube 11 is provided with evenly distributed filtering holes 111. The outer walls on both sides of each square tube 10 are slidably installed with an adapter seat 16 along its axial direction, and the bottom outer wall of the rotating ring plate 601 is fixedly installed with two pairs of inclined fixed rods 603, and the ends of the fixed rods 603 are rotatably connected to the adapter seat 16.

[0049] Through the above structure, when the rotating main pipe 4 rotates, it can drive the square pipe 10 to rotate, and at the same time, the adapter seat 16 and the fixed pull rod 603 provided can drive the rotating ring plate 601 to rotate, thereby realizing the mixing operation and the material separation process during the feeding process;

[0050] At the same time, when the rotating main pipe 4 moves vertically under the action of the driving assembly, the set 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 connecting pipe 11, thereby changing the angle of the connecting pipe 11 and making the material suction range wider.

[0051] As a further solution of the present invention, an extended side rod 14 is fixedly installed on the outer wall of one side of the two square tubes 10, and a transmission rod 141 is fixedly installed on the end of the extended side rod 14. An elongated circular groove 901 is provided on the outer wall of one side of the two swing plates 9, and the transmission rod 141 is movably matched with the elongated circular groove 901. Each swing plate 9 is provided with evenly distributed turbulence grooves 902.

Then, 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, thereby ensuring the stirring effect of the material.

A pair of branch tubes 8 are fixedly connected to one end of the rotating main pipe 4 near the top, and a one-way valve 2 801 is fixedly installed on each branch tube 8, and the output direction of the one-way valve 2 801 is toward 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, the space at the bottom of the piston column 301 increases, thereby utilizing the negative pressure effect to extract the liquid in the enzymatic hydrolysis tank 1 through the filter through hole 111 on the connecting tube 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 tube 7 and the one-way valve 3 701.

[0054] When the rotating main pipe 4 moves upward, the space at the bottom of the piston column 301 decreases, thereby transferring the sucked liquid and air through the one-way valve 1 402 to the subsequent sector plate 12 and bulging out through the tree-like diversion grooves 121, thereby utilizing cavitation to achieve the purpose of improving the homogenization effect. In addition, the space at the top of the piston column 301 increases, and the negative pressure effect is used to re-extract air into the rotating main pipe 4 through the branch pipe 8 and the one-way valve 2 801.

[0055] As a further embodiment of the present invention, Figure 3-Figure 5As shown, the bottom end of the rotating main pipe 4 is fixedly connected to the fan-shaped plate 12, and the fan-shaped plate 12 is provided with a tree-shaped diversion groove 121 connected to the rotating main pipe 4. A one-way valve 402 is fixedly installed at one end of the rotating main pipe 4 close to the fan-shaped plate 12, and the output direction of the one-way valve 402 is output 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 fan-shaped plate 12 to rotate, playing a role in auxiliary stirring; and the provided tree-shaped diversion groove 121 can re-divert air and material, further improving the cavitation effect on the material.

[0056] As a further embodiment of the present invention, Figure 1 、 Figure 2 as well as Figure 6 As shown, the driving assembly includes a pair of electric push rods 2 fixedly mounted on the top of the enzymolysis tank 1, and the ends of the extension rods of the two electric push rods 2 are jointly fixedly mounted with a mounting plate 201, and the mounting plate 201 is rotatably connected to the rotating main pipe 4 through a bearing, a supporting outer frame 101 is fixedly mounted on the outer peripheral wall of the enzymolysis tank 1, and one end of the outer peripheral wall of the enzymolysis tank 1 near the top is fixedly connected to a feed pipe 103, and the bottom end of the enzymolysis tank 1 is fixedly connected to a valved discharge pipe 102; after the protein enzymolysis is completed, the valve on the valved discharge pipe 102 can be opened to perform unloading operations.

[0057] Furthermore, a driven conical tooth 401 is fixedly mounted on the outer peripheral wall of the rotating main tube 4 , a driving motor 5 is fixedly mounted on the mounting plate 201 , and a driving conical tooth 501 is fixedly mounted on the output shaft of the driving motor 5 , and the driving conical tooth 501 is meshed with the driven conical tooth 401 .

[0058] Through the above structure, the electric push rod 2 is provided, which 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, the driving conical teeth 501 and the driven conical teeth 401 can drive the rotating main pipe 4 to rotate to perform the stirring operation.

[0059] The specific working method is as follows: when in use, the driving motor 5 is controlled to start, and the driving conical gear 501 and the driven conical gear 401 are driven to rotate, and when the rotating main pipe 4 rotates, the square tube 10 can be driven to rotate, and at the same time, the adapter 16 and the fixed pull rod 603 are coordinated to drive the rotating plate 601 to rotate. The material added to the enzymatic hydrolysis tank 1 will first fall on the rotating plate 601, and then be diverted through the multiple arc grooves 602 provided. Finally, the rotation of the rotating plate 601 is coordinated to achieve the purpose of uniform feeding.

[0060] 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 lever point to make the square pipe 10 swing along the connecting pipe 11, thereby changing the angle of the connecting pipe 11, making the material suction range wider; when the square pipe 10 swings along the connecting pipe 11, it can synchronously drive the extended side rod 14 to swing, and with the cooperation of the transmission rod 141 and the oblong groove 901, the elevation angle of the swing plate 9 is synchronously adjusted, and then 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, thereby ensuring the stirring effect of the material;

[0061] When the rotating main pipe 4 moves downward, since the piston column 301 and the plug column 303 are fixed, the space at the bottom of the piston column 301 increases, thereby utilizing the negative pressure effect to extract the liquid in the enzymolysis tank 1 through the filter through hole 111 on the connecting tube 11. At the same time, the space at the top of the piston column 301 decreases, thereby pressing the air above the piston column 301 into the lower end of the rotating main pipe 4 through the side pipe 7 and the one-way valve 3 701; when the rotating main pipe 4 moves upward, the space at the bottom of the piston column 301 decreases. , thereby transmitting the sucked liquid and air to the subsequent fan-shaped plate 12 through the one-way valve 402, and bulging out through the tree-like diversion groove 121, thereby utilizing the cavitation effect to achieve the purpose of improving the homogenization effect; in addition, the space on the top of the piston column 301 is increased, and the negative pressure effect is utilized to re-extract air into the rotating main pipe 4 through the branch pipe 8 and the one-way valve 801. The above operation can achieve effective homogenization of the material; after the protein enzymatic hydrolysis is completed, the valve on the valved discharge pipe 102 can be opened to carry out the unloading operation.
