Description

Technical Field

[0001] The invention relates to the technical field of sodium hyaluronate gel production, in particular to a microbial fermentation mechanism for sodium hyaluronate gel production. Background Art

[0002] Sodium hyaluronate gel is a gel-like substance made from sodium hyaluronate. Sodium hyaluronate gel is often used in skin care products to provide deep moisturizing to the skin, repair the skin barrier, and reduce wrinkles.

[0003] The production of sodium hyaluronate gel usually uses microbial fermentation, and the microbial fermentation tank is the core equipment to achieve this process. The fermentation tank is a closed reactor that can provide a suitable environment for the growth and metabolism of microorganisms, such as temperature, pH value, oxygen supply and stirring rate. The microorganisms in the fermentation tank produce hyaluronic acid through the fermentation process, and then through subsequent extraction, purification and modification, sodium hyaluronate is obtained, and finally a gel product is made.

[0004] During the fermentation process, a culture medium containing a carbon source, a nitrogen source, minerals and other necessary nutrients needs to be prepared in the fermenter, and then the pre-cultured microorganisms (such as Streptococcus or Staphylococcus) are inoculated into the fermenter, and finally the liquid is stirred by the stirring component in the fermenter.

[0005] However, during the fermentation process, microorganisms need to be provided with sufficient oxygen, which is usually achieved by bubbling air. Since surface tension is generated when gas contacts liquid, bubbles are formed. Secondly, mechanical stirring in the fermentation tank will release dissolved gases in the liquid and form bubbles. Bubbles will gradually accumulate and float on the liquid surface. The foam will affect the transmission of gas in the fermentation liquid, reduce the ventilation effect, and further affect the growth and metabolic process of microorganisms. Secondly, the existing oxygen supply method mainly transports oxygen to the fermentation tank through an oxygen supply pipe. The oxygen is not evenly distributed in the liquid, especially when the liquid is deep. The microorganisms at the bottom often do not get enough oxygen, which affects the fermentation effect. To this end, we propose a microbial fermentation mechanism for the production of sodium hyaluronate gel. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 8 A microbial fermentation mechanism for producing sodium hyaluronate gel, comprising a tank body 5, a feed pipe 6 and an exhaust pipe 2 installed on the top of the tank body 5, a discharger 3 installed at the bottom of the tank body 5, and an oxygen supply pipe 4 symmetrically fixedly penetrating the inner wall of the tank body 5, a motor 1 is fixedly installed at the top of the tank body 5, a cylindrical barrel 7 is fixedly connected to the output shaft end of the motor 1, the cylindrical barrel 7 movably penetrates the inner wall of the top of the tank body 5, a stirring assembly is arranged at the bottom end of the cylindrical barrel 7, a plurality of bubble breaking mechanisms are arranged between the cylindrical barrel 7 and the tank body 5, and a turbulent mechanism is arranged on both oxygen supply pipes 4;

[0030] The bubble breaking mechanism includes a transverse plate 9, which is connected to the outer wall of the cylindrical tube 7 through an elastic mechanism. A plurality of connecting columns 10 are slidably inserted through the inner wall of the transverse plate 9. The bottom ends of the plurality of connecting columns 10 are fixedly connected with U-shaped floating shells 11. Two adjacent U-shaped floating shells 11 fit each other. The bottoms of the plurality of U-shaped floating shells 11 are fixedly connected with a plurality of spikes 18. A clamping mechanism is provided between the plurality of connecting columns 10 and the cylindrical tube 7.

[0031] The stirring assembly comprises a main shaft 12 , which is fixedly connected to the bottom end of the cylindrical barrel 7 , and a plurality of stirring blades 13 are fixedly sleeved on the outer wall of the main shaft 12 .

[0032] Specifically, when the cylindrical barrel 7 rotates, the main shaft 12 and the plurality of stirring blades 13 are driven to rotate together, thereby facilitating stirring of the fermentation liquid.

[0033] The elastic mechanism includes a slide groove 15, which is opened on the outer wall of the cylindrical tube 7 near the lower edge. A slider 25 is fitted on the bottom inner wall of the slide groove 15. The end of the slider 25 located outside the cylindrical tube 7 is fixedly connected to the end of the cross plate 9 near the cylindrical tube 7. The upper end of the slider 25 is fixedly connected to a connecting rod 28. A fixed block 27 is slidably sleeved on the outer wall of the connecting rod 28 near the upper edge. One end of the fixed block 27 is fixedly connected to the inner wall of the cylindrical tube 7. A spring 26 is fixedly connected between the fixed block 27 and the slider 25. The spring 26 is slidably sleeved on the outer wall of the connecting rod 28.

[0034] The clamping mechanism includes multiple square rods 21, which are slidably inserted into one side wall of the cross plate 9. The multiple square rods 21 correspond to the positions of the multiple connecting columns 10 respectively. One ends of the multiple square rods 21 corresponding to the connecting columns 10 are fixedly connected with rubber blocks 24. The multiple rubber blocks 24 are respectively close to the multiple connecting columns 10. Elastic mechanisms are provided between the multiple square rods 21 and the cross plate 9. The upper ends of the multiple square rods 21 are fixedly connected with triangular blocks 19 away from the cross plate 9. The upper edges of the inclined surfaces of the multiple triangular blocks 19 are jointly fitted with a limiting rod 17, and an L-shaped rod 16 is fixedly connected between one end of the limiting rod 17 and the outer wall of the cylindrical tube 7.

[0035] The elastic mechanism includes two U-shaped blocks 20, and the two U-shaped blocks 20 are respectively fixedly connected to the two side walls of the square rod 21 away from the horizontal plate 9. The inner walls of the two U-shaped blocks 20 are slidably interspersed with guide columns 22, and one end of the two guide columns 22 is fixedly connected to the side wall of the horizontal plate 9. The outer walls of the two guide columns 22 are slidably sleeved with springs 23, and the two springs 23 are respectively fixedly connected between the two U-shaped blocks 20 and the horizontal plate 9.

[0036] The bubble breaking mechanism also includes an arc block 8 and a plurality of limit plates 14. The plurality of limit plates 14 are respectively fixedly connected to the top ends of the plurality of connecting columns 10. The lower ends of the plurality of limit plates 14 are all in contact with the upper ends of the transverse plates 9. The arc block 8 is fixedly connected to the inner wall of the tank body 5 near the transverse plate 9. The upper end surface of the arc block 8 is a slope.

[0037] In this embodiment, raw materials such as culture medium and pre-cultured microorganisms can be placed into the tank body 5 along the feed pipe 6, and then the feed pipe 6 is sealed with a tube cover. The oxygen supply pipe 4 can be connected to the pipeline of the existing oxygen delivery equipment to transport oxygen into the tank body 5. The exhaust pipe 2 can be connected to the pipeline of the existing equipment for treating exhaust gas. The tank body 5 has its own temperature control system. This is a well-known existing technology and will not be elaborated on.

[0038] Then, the motor 1 is started to drive the cylindrical barrel 7 and the stirring assembly to rotate together, so as to stir the fermentation liquid and promote mixing. When the cylindrical barrel 7 rotates, it can drive the multiple fixed blocks 27 to rotate. Each fixed block 27 can drive the connected connecting rod 28, spring 26, slider 25 and cross plate 9 to rotate together. Each cross plate 9 can drive the connected multiple connecting columns 10 and multiple U-shaped floating shells 11 to rotate together. The multiple U-shaped floating shells 11 can float on the liquid surface. It is worth mentioning that when the culture medium and the pre-cultured microorganisms are placed in the tank body 5, as the liquid level rises, the liquid surface will contact the bottom of the multiple U-shaped floating shells 11, and as the liquid level continues to rise, the multiple U-shaped floating shells 11 will float up, and each U-shaped floating shell 11 will drive the connected connecting column 10 to slide up in the horizontal plate 9. When the middle of the connecting column 10 rises to correspond to the horizontal plate 9, the liquid level stops rising, and the culture medium and the pre-cultured microorganisms are added at this time. When the stirring component stirs the liquid, the liquid level height near the stirring component area will be lower than the liquid level height away from the stirring component area (this is because the centrifugal force brought by the stirring liquid causes the liquid to flow outward from the stirring center area, causing the liquid level near the stirring component to lower). At this time, the height of the U-shaped floating shell 11 near the stirring component will be lower than the height of the U-shaped floating shell 11 away from the stirring component, thereby adapting to the change in liquid level. At the same time, when the U-shaped buoy 11 rotates on the liquid surface, the spikes 18 at the bottom thereof will continuously puncture the bubbles generated during the fermentation process, thereby preventing the bubbles from accumulating on the liquid surface, affecting the transmission of gas in the fermentation liquid and reducing the ventilation effect, and affecting the growth and metabolic process of the microorganisms.

[0039] It should be noted that each cross plate 9 will pass through the slope of multiple arc blocks 8 in sequence when rotating. When each cross plate 9 passes through an arc block 8, the cross plate 9 will first move up along the slope. At this time, the cross plate 9 will drive the slider 25 to slide upward in the corresponding slide groove 15, and the slider 25 will drive the corresponding connecting rod 28 to slide up in the corresponding fixed block 27 and squeeze the spring 26. The cross plate 9 will also drive multiple square rods 21 and multiple guide columns 22 to move upward. The multiple square rods 21 can drive the rubber blocks 24, triangular blocks 19 and U-shaped blocks 20 connected to each other to move upward together. The inclined surfaces of the multiple triangular blocks 19 will squeeze the limiting rod 17, and the limiting rod 17 is fixed to the cylindrical tube 7 through the L-shaped rod 16. Then, the multiple triangular blocks 19 will move toward the direction of the cross plate 9 and always keep in contact with the limiting rod 17. The multiple triangular blocks 19 can drive the U-shaped blocks 20 connected to each other to slide outside the corresponding guide column 22 and squeeze the spring 1 23, and the multiple triangular blocks 1 9 can drive the square rods 21 connected to each other to slide into the cross plate 9, and the multiple square rods 21 can drive the rubber blocks 24 connected to each other to squeeze the corresponding connecting columns 10, thereby clamping the multiple connecting columns 10. As the cross plate 9 continues to move upward, the clamped multiple connecting columns 10 will also move upward, and the multiple U-shaped floating shells 11 will also move upward. As the cross plate 9 continues to move upward, the multiple rubber blocks 24 will squeeze and deform and always clamp the corresponding connecting columns 10 until the cross plate 9 leaves the arc block 8. At this time, under the action of the spring second 26, the cross plate 9 will automatically move downward. Under the action of the spring one 23, each cross plate 9 will move away from the corresponding connecting column 10, then each rubber block 24 will loosen the corresponding connecting column 10, then the multiple connecting columns 10 and the multiple U-shaped floating shells 11 will move downward, and the multiple U-shaped floating shells 11 will hit the liquid surface, thereby beating and vibrating the liquid surface, thereby further eliminating bubbles, and further preventing bubbles from affecting the growth and metabolic process of microorganisms. At the same time, when the fermentation liquid is subsequently discharged along the discharge device 3, the up and down movement of the multiple U-shaped floating shells 11 will also cause the liquid adhering to the bottom to be quickly shaken off, reducing adhesion and making the discharge more thorough.

[0040] Example 2: Please refer to Figure 7 The spoiler mechanism includes a fixing frame 29, which is fixedly connected to the outer wall of the oxygen supply pipe 4. A pillar 34 is slidably inserted into the middle inner wall of the fixing frame 29. A connecting plate 30 is fixedly connected to one end of the pillar 34 close to the oxygen supply pipe 4. The connecting plate 30 is rotatably connected to a conical rubber plug 31 away from the wall of the pillar 34. The conical surface of the conical rubber plug 31 fits the end of the oxygen supply pipe 4. A spring three 33 is fixedly connected between the wall of the connecting plate 30 corresponding to the pillar 34 and the fixing frame 29. The spring three 33 is slidably sleeved on the outer wall of the pillar 34.

[0041] The spoiler mechanism further includes a plurality of blades 32 , which are fixedly connected to the outer wall of the conical rubber plug 31 in a central annular array around the conical rubber plug 31 , and the plurality of blades 32 are all arranged at an inclination.

[0042] In this embodiment, when oxygen is introduced into the oxygen supply tube 4, under the action of air pressure, the conical rubber plug 31 will be pushed outward, the conical rubber plug 31 will drive the connecting plate 30 to move together, the connecting plate 30 will drive the support 34 to slide outward in the fixing frame 29, and the connecting plate 30 will also squeeze the spring three 33 connected to the fixing frame 29, so that oxygen is ejected from the gap between the outer wall of the conical rubber plug 31 and the end of the oxygen supply tube 4, and the oxygen will be ejected in a ring form along the conical surface of the conical rubber plug 31. At the same time, the oxygen will also pass through the gaps between the multiple blades 32, causing the multiple blades 32 to rotate with the conical rubber plug 31, so that the oxygen will be in a ring shape and ejected in a rotating manner, so that the oxygen will be more evenly distributed in the liquid, and the fermentation liquid at the bottom of the tank body 5 will also be fully exposed to the oxygen, thereby improving the fermentation effect.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
