Description

Technical Field

[0001] This utility model relates to the field of active substance fermentation technology, specifically an active substance fermentation device. Background Technology

[0002] Fermentation is required in the preparation of active ingredients. During the fermentation process, oxygen needs to be added to the fermentation solution to increase its oxygen content and bring it within the normal range. The current method for increasing the oxygen content of the fermentation solution is to add sterile air or oxygen to the fermenter and then stir the fermentation solution to dissolve the oxygen and increase its oxygen content. However, this method is inefficient and time-consuming, and the bottom layer of the fermentation solution takes a long time to reach the average oxygen content level, resulting in low overall efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an active substance fermentation device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the active substance fermentation device includes a tank: A stirring tube is rotatably connected to the tank body, and the upper end of the stirring tube is open. The tank is equipped with a drive mechanism for driving the stirring tube to rotate. The tank is equipped with an air supply module for supplying air into the stirring tube. The air supply module is fixed at the upper end of the tank and is rotatably connected to the stirring tube. The outer surface of the middle part of the stirring tube is uniformly provided with exhaust pipes, and the exhaust pipes are in communication with the stirring tube. The lower surface of the exhaust pipe is provided with an air hole, and an elastic plug is installed inside the air hole. An air passage is provided inside the plug. The air passage is normally closed. When the air pressure in the exhaust pipe is greater than the force that closes the air passage, the gas in the exhaust pipe can be discharged outward through the air passage. A central tube is provided above the bottom of the tank body. The central tube is fixed to the inner wall of the tank body by a side rod. A spiral blade is provided on the lower outer surface of the stirring tube. The spiral blade is located inside the central tube.

[0005] Preferably, both the upper and lower ends of the central tube are flared.

[0006] Preferably, the tank body includes a bottom tank and a top cover. A cover is provided on the top cover. The upper end of the stirring tube passes through the cover. A protrusion is provided on the side of the cover. The driving mechanism includes a horizontal shaft provided in the protrusion. A bevel gear is provided at one end of the horizontal shaft and on the outer surface of the stirring tube. The two bevel gears mesh with each other. A motor module for driving the horizontal shaft to rotate is installed on one side of the protrusion.

[0007] Preferably, the gas supply module includes a fixing block, which is fixed to the upper end of the cover. The fixing block has a through groove inside, and connecting pipes are respectively provided at both ends of the through groove. One of the connecting pipes is located inside the stirring pipe. The module also includes a sealing element, which is located between the inner wall of the stirring pipe and the outer wall of the connecting pipe, and contacts both the stirring pipe and the connecting pipe simultaneously.

[0008] Preferably, the inner side of the top cover is provided with a mounting groove, and a sealing ring is provided inside the mounting groove.

[0009] The beneficial effects of this utility model are: This fermentation device increases the oxygen content of the fermentation solution by directly introducing sterile air into the solution through the air passage on the stopper. Then, through the stirring of the exhaust pipe, the oxygen content of the fermentation solution is rapidly replenished. Furthermore, through the cooperation of the spiral blades and the central tube, the fermentation solution in the tank can be circulated, allowing the upper and lower layers of fermentation solution to continuously change positions. This ensures that the oxygen content of the fermentation solution in all parts of the tank is increased more evenly, thus avoiding the problem of excessive local differences and helping to shorten the fermentation time and improve the fermentation efficiency.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, an active ingredient fermentation apparatus includes a tank: A stirring tube 3 is rotatably connected to the tank body, and the upper end of the stirring tube 3 is open; The tank is equipped with a drive mechanism for rotating the stirring tube 3; The tank is equipped with an air supply module for supplying air into the stirring tube 3. The air supply module is fixed at the upper end of the tank and is rotatably connected to the stirring tube 3. The outer surface of the middle part of the stirring tube 3 is uniformly provided with exhaust pipes 4, and the exhaust pipes 4 are connected to the stirring tube 3. The lower surface of the exhaust pipe 4 has an air hole, and an elastic plug 5 is installed inside the air hole. The plug 5 has an air passage inside, which is normally closed. When the air pressure in the exhaust pipe 4 is greater than the force of closing the air passage, the gas in the exhaust pipe 4 can be discharged out through the air passage. A central tube 6 is installed above the bottom of the tank. The central tube 6 is fixed to the inner wall of the tank by a side rod. A spiral blade 7 is installed on the lower outer surface of the stirring tube 3. The spiral blade 7 is located inside the central tube 6.

[0017] The air supply module is connected to an air source containing sterile air. This sterile air is supplied to the fermentation solution through the air supply module, stirring pipe 3, exhaust pipe 4, stopper 5, and the air passage on stopper 5. Once the sterile air enters the tank, the motor module 12 is activated. The motor module 12 includes a servo motor and a reducer at the output of the servo motor. The motor module 12 drives the horizontal shaft 10 to rotate, and through the meshing of the horizontal shaft 10 and two bevel gears 11 on the stirring pipe 3, it drives the stirring pipe 3 to rotate. The air supply module does not rotate with the stirring pipe 3; the stirring pipe 3 rotates... During the process, the exhaust pipe 4 is rotated. The exhaust pipe 4 is located in the fermentation solution. While the exhaust pipe 4 is stirring the fermentation solution in the tank, sterile air is discharged into the fermentation solution through the air passage on the plug 5. The stirring action of the exhaust pipe 4 can quickly increase the oxygen content in the fermentation solution. The oxygen content is detected by an online dissolved oxygen probe and connected to the controller of the fermentation device. When the oxygen content is within the normal range, the external air source stops supplying sterile air into the tank. When the oxygen content is lower than the normal range, the external air source starts to replenish sterile air into the tank.

[0018] During the rotation of the stirring tube 3, the spiral blades 7 will rotate. As the spiral blades 7 rotate inside the central tube 6, they will push the fermentation solution downward. The fermentation solution will flow out from below the central tube 6 and move upward through the outside of the central tube 6, thus forming a circulation to ensure that the oxygen content of the fermentation solution in all positions in the tank is at a relatively uniform level.

[0019] Both the central tube 6 and the spiral blade 7 are made of metal. When the spiral blade 7 rotates, it will not directly contact the inner surface of the central tube 6, thus avoiding friction between the two and generating noise.

[0020] Furthermore, both the upper and lower ends of the central tube 6 are designed in a funnel shape, which facilitates the entry of the fermentation solution into the central tube 6 and also facilitates the discharge of the fermentation solution from the central tube 6. Alternatively, only the upper end of the central tube 6 can be designed in a funnel shape, which can accelerate the speed at which the fermentation solution flows out of the central tube 6. Since the flowing fermentation solution is directed directly towards the bottom of the tank, it can prevent the accumulation of substances at the bottom of the tank and make the substances in the tank more evenly dispersed.

[0021] Furthermore, the tank body includes a bottom tank 1 and a top cover 2. A cover 8 is provided on the top cover 2. The upper end of the stirring tube 3 passes through the cover 8. A protrusion 9 is provided on the side of the cover 8. The driving mechanism includes a horizontal shaft 10 provided in the protrusion 9. A bevel gear 11 is provided at one end of the horizontal shaft 10 and on the outer surface of the stirring tube 3. The two bevel gears 11 mesh with each other. A motor module 12 for driving the horizontal shaft 10 to rotate is installed on one side of the protrusion 9.

[0022] The horizontal shaft 10 and the protrusion 9, the stirring tube 3 and the cover 8, and the stirring tube 3 and the top cover 2 are all connected by bearings.

[0023] Furthermore, the gas supply module includes a fixing block 13, which is fixed to the upper end of the cover 8. The fixing block 13 has a through groove inside, and connecting pipes 14 are respectively provided at both ends of the through groove. One of the connecting pipes 14 is located inside the stirring pipe 3. It also includes a sealing element 15, which is located between the inner wall of the stirring pipe 3 and the outer wall of the connecting pipe 14, and contacts both the stirring pipe 3 and the connecting pipe 14. The sealing element 15 can increase the sealing between the stirring pipe 3 and the connecting pipe 14 to reduce gas leakage.

[0024] Furthermore, an installation groove 16 is provided on the inner side of the top cover 2, and a sealing ring 17 is provided inside the installation groove 16. The sealing ring 17 can increase the sealing between the installation groove 16 and the stirring tube 3 to reduce gas leakage.

[0025] The tank also includes a heating system, a feeding system, a discharging system, a sterilization system, a cooling system, a pH control system, and a detection system. Since these are all existing technologies, they will not be described in detail here.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
