Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fermentation treatment kettle, in particular to a strain fermentation treatment kettle for natural emulsifier preparation process and a treatment method. BACKGROUND

[0002] The emulsifier is a key raw material in the field of emulsifier cosmetics, etc., which is used to improve the compatibility of oil-water system and improve product stability; the mainstream products on the market are mostly chemical synthetic emulsifiers (such as polysorbate, sodium stearoyl lactylate, etc.), which have good emulsifying effect, but have the problems of poor biocompatibility, possible skin irritation or gastrointestinal discomfort caused by long-term use, and do not meet the needs of consumers for "natural and safe" products; The bacillus fermentation product is considered as an ideal natural emulsifier raw material due to its good emulsifying performance and biological safety; however, in the mixing process of the bacillus fermentation product and glycerol, etc., the traditional stirring equipment often has the problems of uneven mixing, low stirring efficiency, easy production of dead angles, and difficult cleaning, which seriously affect the product quality and production efficiency of the emulsifier. SUMMARY

[0003] The purpose of the present application is to provide a strain fermentation treatment kettle for natural emulsifier preparation process and a treatment method to solve the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A strain fermentation treatment kettle for natural emulsifier preparation process, comprising a kettle body, a feed inlet is arranged at the top of the kettle body, a discharge outlet is arranged at the bottom of the kettle body, a mixing assembly is arranged in the kettle body, a driving motor is further arranged at the top of the kettle body, the mixing assembly is driven by the driving motor, the mixing assembly comprises a rotating shaft and a plurality of stirring bodies, the stirring bodies are arranged on the rotating shaft, and the rotating shaft is rotatably connected with the kettle body.

[0005] The bacillus fermentation product and glycerol are input into the kettle body through the feed inlet according to a ratio of 1:16-20, then the controller controls the driving motor to start, the driving motor drives the mixing assembly to rotate, the rotating shaft drives the plurality of stirring bodies to rotate, and the stirring bodies mix and stir the bacillus fermentation product and glycerol in the rotating process, so that the two are fully mixed, and finally a uniform and stable emulsifier raw material is formed.

[0006] Preferably, the stirring body is composed of two moving rings and a plurality of stirring plates, the two moving rings and the two stirring plates are symmetrically arranged at the two ends of the rotating shaft, the two stirring plates are hinged through a hinge rod, the stirring plates are hinged with the moving rings through the hinge rod, two groups of bidirectional threads are arranged on the shaft wall of the rotating shaft, and the moving rings are threadedly engaged with the rotating shaft.

[0007] Because the moving ring engages with the thread on the shaft wall of the rotating shaft, the rotating shaft drives the moving ring to move during rotation. The moving ring moves along the axis of the rotating shaft, so that the two moving rings are in a state of moving towards each other. Since the shaft wall of the rotating shaft is provided with a bidirectional thread, the two moving rings move to opposite sides after they come into contact with each other, so that the two moving rings reciprocate along the axis of the rotating shaft. As the moving plates move towards each other, they push the stirring plates to move, causing the end of the stirring plate away from the moving ring to move towards the side of the stirring body away from the rotating shaft. As a result, several stirring plates will change from a vertical state to a horizontal state. When the two moving rings move to the middle of the rotating shaft, the two moving rings contact each other, and at this time, several stirring plates are in a horizontal state. As the two moving rings reciprocate along the rotation axis, the arrangement of several stirring plates also changes with the movement of the moving rings, causing the several stirring plates to switch back and forth between vertical and horizontal states. When the rotating shaft drives several stirring bodies to rotate, it agitates the Bacillus fermentation products and glycerol in the vessel. Meanwhile, the two moving rings drive several stirring plates to switch their arrangement states during the reciprocating motion. During the state switching of the stirring plates, the stirring plates agitate the Bacillus fermentation products and glycerol in the vessel, causing the Bacillus fermentation products and glycerol to flow in the space between the stirring plates, thereby improving the mixing efficiency of the Bacillus fermentation products and glycerol.

[0008] Preferably, the stirring plate is provided with a plurality of movable grooves, a movable plate is provided in the movable groove, a spring is provided between the movable plate and the movable groove, and the movable plate and the movable groove are slidably and sealingly connected.

[0009] During the rotation of the stirring plate, the stirring plate drives the moving plate to rotate, which in turn agitates the Bacillus fermentation products and glycerol. When the stirring plates change from a vertical to a horizontal position, the sides of the two stirring plates arranged vertically and horizontally near the rotating shaft move towards each other, causing the ends of the moving plates near the rotating shaft to come into contact with each other and press against each other. As a result, the moving plates move along the moving groove, causing the ends of the moving plates away from the rotating shaft to move closer to the cleaning strip. This increases the area of ​​the moving plates on the side of the stirring plates closest to the cleaning strip, thereby increasing the contact area between the Bacillus fermentation products and glycerol and the moving plates, and thus improving the mixing effect of the Bacillus fermentation products and glycerol. When the mixing plate switches from a horizontal to a vertical position, the moving plates move away from each other. Then, the moving plates are reset by the action of the spring, causing the end of the moving plate near the cleaning strip to retract. This increases the contact area between the end of the moving plate near the rotating shaft and the Bacillus fermentation products and glycerol, thereby improving the mixing efficiency of the Bacillus fermentation products and glycerol between the mixing body and the rotating shaft.

[0010] Preferably, a cleaning strip is provided on the side of the stirring body away from the rotating shaft, and a hinge plate is provided on the side of the cleaning strip close to the stirring body. The ends of the two stirring plates away from the moving ring are hinged to the hinge plate.

[0011] As the moving rings move towards each other, they drive the stirring plate to move. One end of the stirring plate moves closer to the inner wall of the vessel, which in turn pushes the cleaning strip to move closer to the inner wall of the vessel. During the movement, the cleaning strip comes into contact with the surface of the vessel, allowing it to scrape the surface of the vessel and prevent the fermentation products of Bacillus subtilis and glycerol from sticking to the inner wall of the vessel. As the moving ring is in a reciprocating motion, the cleaning strip will also intermittently contact the surface of the vessel. During the reciprocating motion of the cleaning strip, it will also promote the flow of Bacillus fermentation products and glycerol in the vessel, further agitating the Bacillus fermentation products and glycerol.

[0012] Preferably, the cleaning strip has several conveying grooves on the side near the mixing body, and the conveying grooves correspond one-to-one with the spaces between two adjacent moving plates.

[0013] As the cleaning strip moves, it drives the conveying trough to move as well. This movement causes the Bacillus fermentation products and glycerol to move, and the conveying trough works in conjunction with the two adjacent moving plates to further agitate the Bacillus fermentation products and glycerol.

[0014] Preferably, a planetary gear set is provided at the bottom of the rotating shaft, and a rotating impeller is provided on the outside of the planetary gear set, and the rotating impeller is rotatably connected to the planetary gear set.

[0015] During rotation, the rotating shaft meshes with the planetary gear set, which in turn drives the planetary gear set to rotate. This rotation of the planetary gear set, in turn, drives the rotating impeller to rotate, which in turn agitates the Bacillus fermentation products and glycerol located at the bottom of the vessel.

[0016] Preferably, the rotation direction of the rotating impeller is opposite to the rotation direction of the rotating shaft.

[0017] The impeller rotates in the opposite direction to the shaft, causing the Bacillus fermentation products and glycerol located near the shaft and the impeller to form a turbulent water flow, thereby further improving the mixing effect of the Bacillus fermentation products and glycerol.

[0018] A process for treating a fermentation vessel used in the preparation of a natural emulsifier, the process comprising the following specific steps: S1. Add the Bacillus fermentation product and glycerol into the reactor at a ratio of 1:16-20; S2. Start the drive motor, and the drive shaft of the drive motor will drive the rotating shaft to rotate; S3. When the rotating shaft rotates, it drives the two moving rings to move back and forth. S4. When the moving ring moves, it drives the stirring plate to move. During the movement, the stirring plate agitates the Bacillus fermentation products and glycerol. S5. During the movement of the stirring plate, the cleaning strip moves, and the cleaning strip pushes the Bacillus fermentation products and glycerin, and scrapes the inner wall of the reactor. S6. After mixing, the emulsifier is discharged from the reactor through the outlet.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The rotating shaft with a bidirectional thread structure drives the moving ring to reciprocate, thereby causing the stirring plate to switch between vertical and horizontal states, thus forming a dynamic stirring zone in the vessel. At the same time, the stirring plate is equipped with a retractable moving plate structure. During the switching of the stirring plate state, the moving plate automatically extends and retracts, changing the contact area with the material, further improving the stirring intensity and mixing efficiency.

[0020] 2. A cleaning strip is provided at the end of the stirring body. As the stirring plate moves, the cleaning strip intermittently contacts the inner wall of the vessel, automatically scraping off the attached material and effectively preventing fermentation products and glycerol from adhering to and remaining on the vessel wall.

[0021] 3. The impeller is driven by a planetary gear set to rotate in the opposite direction to the rotating shaft, forming a reverse flow field at the bottom of the vessel, eliminating the laminar flow state formed by unidirectional stirring, and further enhancing the overall mixing effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: Figures 1-7 As shown, the present invention provides a fermentation treatment vessel and treatment method for the preparation of natural emulsifiers, comprising a vessel body 1, an inlet 11 at the top of the vessel body 1, an outlet 12 at the bottom of the vessel body 1, a mixing component 2 inside the vessel body 1, and a drive motor at the top of the vessel body 1.

[0025] In one specific embodiment of the present invention, the stirring body 22 is composed of two moving rings 23 and several stirring plates 24. The two moving rings 23 and the two stirring plates 24 are symmetrically arranged at both ends of the rotating shaft 21. The two stirring plates 24 are hinged by a hinge rod. The stirring plates 24 and the moving rings 23 are hinged by a hinge rod. The shaft wall of the rotating shaft 21 is provided with two sets of bidirectional threads, and the moving rings 23 are threadedly engaged with the rotating shaft 21.

[0027] In one specific embodiment of the present invention, a cleaning strip 27 is provided on the side of the stirring body 22 away from the rotating shaft 21, and a hinge plate 28 is provided on the side of the cleaning strip 27 close to the stirring body 22. The ends of the two stirring plates 24 away from the moving ring 23 are hinged to the hinge plate 28.

[0028] In one specific embodiment of the present invention, the cleaning strip 27 is provided with a plurality of conveying grooves 29 on the side near the stirring body 22, and the conveying grooves 29 correspond one-to-one with the spaces between two adjacent moving plates 26.

[0029] In one specific embodiment of the present invention, a planetary gear set 31 is provided at the bottom of the rotating shaft 21, and a rotating impeller 30 is provided on the outside of the planetary gear set 31, and the rotating impeller 30 is rotatably connected to the planetary gear set 31.

[0030] In one specific embodiment of the present invention, the rotation direction of the rotating impeller 30 is opposite to the rotation direction of the rotating shaft 21.

[0031] A process for treating a fermentation vessel used in the preparation of a natural emulsifier, the process comprising the following specific steps: S1. Add the Bacillus fermentation product and glycerol to the reactor body 1 at a ratio of 1:16-20; S2. Start the drive motor, and the drive shaft of the drive motor will drive the rotating shaft 21 to rotate; S3. When the rotating shaft 21 rotates, it drives the two moving rings 23 to move back and forth. S4. When the moving ring 23 moves, it drives the stirring plate 24 to move. During the movement, the stirring plate 24 stirs the Bacillus fermentation product and glycerol. S5. During the movement of the stirring plate 24, the cleaning strip 27 is moved. During the movement of the cleaning strip 27, the Bacillus fermentation product and glycerol are pushed and the inner wall of the vessel 1 is scraped. S6. After mixing, the emulsifier is discharged from the reactor body 1 through the discharge port 12.

[0032] Working principle of the invention: Bacillus fermentation product and glycerol are fed into vessel 1 through feed inlet 11 at a ratio of 1:16-20. Then the controller controls the drive motor to start, and the drive motor drives the mixing component 2 to rotate. The rotating shaft 21 then drives several stirring bodies 22 to rotate. During the rotation, the stirring bodies 22 mix and stir the Bacillus fermentation product and glycerol. Because the moving ring 23 engages with the thread on the shaft wall of the rotating shaft 21, the rotating shaft 21 drives the moving ring 23 to move during rotation. The moving ring 23 moves along the axis of the rotating shaft 21, so that the two moving rings 23 are in a state of moving towards each other. Since the shaft wall of the rotating shaft 21 is provided with a bidirectional thread, the two moving rings 23 move to opposite sides after they come into contact with each other, so that the two moving rings 23 reciprocate along the axis of the rotating shaft 21. As the moving plates 26 move towards each other, they push the stirring plates 24 to move, causing the end of the stirring plates 24 away from the moving rings 23 to move towards the side of the stirring body 22 away from the rotating shaft 21. As a result, several stirring plates 24 will change from a vertical state to a horizontal state. When the two moving rings 23 move to the middle of the rotating shaft 21, the two moving rings 23 come into contact with each other, and at this time, several stirring plates 24 are in a horizontal state. As the two moving rings 23 reciprocate along the rotation axis 21, the arrangement of several stirring plates 24 also changes with the movement of the moving rings 23, causing the several stirring plates 24 to switch back and forth between vertical and horizontal states. When the rotating shaft 21 drives several stirring bodies 22 to rotate, it will stir the Bacillus fermentation products and glycerol in the vessel 1. Meanwhile, the two moving rings 23 drive several stirring plates 24 to switch their arrangement states during the reciprocating movement. During the state switching of the stirring plates 24, the stirring plates 24 will stir the Bacillus fermentation products and glycerol in the vessel 1, so that the Bacillus fermentation products and glycerol flow in the space between the several stirring plates 24. During the rotation of the stirring plate 24, the stirring plate 24 drives the moving plate 26 to rotate, and the moving plate 26 stirs the Bacillus fermentation product and glycerol. When the stirring plates 24 change from a vertical state to a horizontal state, the sides of the two stirring plates 24 arranged vertically and horizontally that are close to the rotating shaft 21 will move towards each other, so that the ends of the moving plates 26 that are close to the rotating shaft 21 will come into contact with each other and press against each other. Then the moving plates 26 will move along the moving groove 25, so that the end of the moving plates 26 away from the rotating shaft 21 will move towards the side close to the cleaning strip 27, thereby increasing the area of ​​the moving plate 26 on the side of the stirring plate 24 that is close to the cleaning strip 27, thereby increasing the contact area between the Bacillus fermentation product and glycerol and the moving plate 26. When the stirring plate 24 switches from a horizontal state to a vertical state, the moving plates 26 move away from each other, and then the moving plates 26 are reset under the action of the spring, causing the end of the moving plate 26 near the cleaning strip 27 to retract, thus increasing the contact area between the end of the moving plate 26 near the rotating shaft 21 and the Bacillus fermentation product and glycerol. As the moving rings 23 move towards each other, they also drive the stirring plate 24 to move. One end of the stirring plate 24 moves closer to the inner wall of the vessel 1, which in turn pushes the cleaning strip 27 to move closer to the inner wall of the vessel 1. During the movement, the cleaning strip 27 comes into contact with the surface of the vessel 1, allowing it to scrape the surface of the vessel 1 and prevent the Bacillus fermentation products and glycerol from sticking to the inner wall of the vessel 1. As the moving ring 23 is in a reciprocating state, the cleaning strip 27 will also reciprocate and intermittently contact the surface of the vessel 1. During the reciprocating movement of the cleaning strip 27, it will also promote the flow of Bacillus fermentation products and glycerol in the vessel 1, further agitating the Bacillus fermentation products and glycerol. As the cleaning strip 27 moves, it will drive the conveying trough 29 to move, which in turn will drive the Bacillus fermentation product and glycerol to move. This allows the conveying trough 29 to cooperate with the two adjacent moving plates 26 to further agitate the Bacillus fermentation product and glycerol. During the rotation of the rotating shaft 21, it meshes with the planetary gear set 31, thereby driving the planetary gear set 31 to rotate. This causes the planetary gear set 31 to drive the rotating impeller 30 to rotate, which in turn agitates the Bacillus fermentation products and glycerol located at the bottom of the vessel 1, ultimately forming a uniform and stable emulsifier raw material, which is then discharged from the outlet 12.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
