This process is usually accompanied by the formation of gases (such as carbon dioxide or hydrogen) and various organic metabolites, such as alcohol, lactic acid, acetic acid, etc.; the fermentation efficiency is affected by the genetic characteristics of the strain and the culture conditions, and is widely used in food, medicine and other fields: the application of microbial fermentation technology in the food field is extensive and far-reaching, especially in the production of various fermented foods; biological fermentation is an important component in bioengineering. Microorganisms can use carbohydrate fermentation to produce various industrial solvents and chemical raw materials. This fermentation process is often carried out in a closed fermentation tank.

[0018] Beneficial effects

[0019] Compared with the prior art, the present invention provides a fermentation mechanism and a fermentation method based on temperature control, which have the following beneficial effects:

[0020] 1. For the fermentation mechanism and the fermentation method based on temperature control, the microbial fermentation of the liquid material is carried out through the fermentation tank body. After a long fermentation process, the temperature inside the fermentation tank becomes higher, or when the external temperature becomes higher, the temperature inside the fermentation tank rises. At this time, it is necessary to cool the liquid material inside the fermentation tank to avoid problems such as deterioration of the liquid material. The turning drive device is started to drive the turning assembly to move up and down, turning the liquid material inside the fermentation tank, so that the liquid material inside the fermentation tank can be mixed, and then the temperature of the liquid material is neutralized. When the temperature inside the fermentation tank continues to rise, through the cooperation of the exchange drive device and the turning drive device, while the turning assembly moves up and down, the liquid material in the built-in exchange cavity of the temperature control assembly is driven to flow into the external cooling cavity, and the cooling plate cools the liquid material in the external cooling cavity. Then the cooled liquid material in the external cooling cavity flows back into the fermentation tank again, so that the cooled liquid material is mixed with the liquid material inside the fermentation tank, thereby realizing the cooling treatment of the liquid material inside the fermentation tank. While the turning assembly moves up and down, it drives the cleaning assembly to move up and down to clean the colony population generated by fermentation on the inner wall of the fermentation tank and drop it into the liquid material. Through the up and down movement of the turning assembly, the colony population is mixed with the liquid material.

[0021] 2. For the fermentation mechanism and the fermentation method based on temperature control, through the bearing provided at the output end of the pushing motor, when moving up and down, the guiding chute provided on the outer surface of the bearing slides vertically along the sliding key inside the angle adjustment drive block. When moving, the bearing moves up and down in the middle of the mounting frame to facilitate observing the position of the bearing, and then judging the height of the turning assembly inside the fermentation tank. At the same time, when it is necessary to adjust the connection between the exchange drive device and the turning drive device, by rotating the angle adjustment drive block, the sliding key in the middle of the angle adjustment drive block cooperates with the guiding chute, so that when the angle adjustment drive block rotates, it can drive the outer ring of the bearing to rotate. Then the outer ring of the bearing drives the pushing rod at its bottom to rotate, thereby realizing the connection between the exchange drive device and the turning drive device.

[0022] 3. In the fermentation mechanism and the fermentation method based on temperature control, when the cold liquid exchange plate in the built-in exchange cavity moves upward, the cooled liquid in the external cooling cavity is pumped into the interior of the built-in exchange cavity, and at the same time, the liquid exchange carrier plate on one side above it is driven to move upward. When the liquid sealing plate outside the liquid exchange carrier plate moves upward, it blocks the liquid flow outlet above the baffle, making the upper part of the external cooling cavity in a closed state. While the cold liquid exchange plate continues to rise, at this time, the cold liquid sealing plate outside the cold liquid exchange plate moves away from the position of the cold liquid return hole, that is, the bottom of the external cooling cavity is in an open state, and thus the liquid flowing through the interior of the external cooling cavity can be pumped into the built-in exchange cavity; when the cold liquid exchange plate moves downward, the cooled liquid at the bottom of the built-in exchange cavity is pushed outward, making the cooled liquid mix with the fermented liquid at a relatively high temperature inside the fermentation tank. At the same time, it drives the liquid exchange carrier plate on one side above it to move, but at this time, the liquid sealing plate outside the liquid exchange carrier plate does not move out of the position of the liquid flow outlet, and the upper part of the external cooling cavity remains in a closed state. When the cold liquid exchange plate moves downward, it pushes the liquid below it and will not push the liquid into the external cooling cavity again; when the cold liquid exchange is completed and the temperature inside the fermentation tank is not yet uniform, the angle of the push rod is adjusted through the angle adjustment drive block, and then the push rod drives the exchange drive device to deflect, so that the carrier block below it moves out of the position of the card slot. At this time, the switching slot and the card slot are in a separated state, that is, the carrier block is in the switching slot on the cold liquid exchange plate, only driving the cold liquid exchange plate to move, and the liquid exchange carrier plate is located above the built-in exchange cavity without moving. When the exchange drive device continues to deflect and the carrier block moves out of the switching slot, that is, the carrier block does not drive the cold liquid exchange plate and the liquid exchange carrier plate to move up and down, that is, the temperature control component stops working.

[0034] During use, the microbial fermentation of the liquid material is carried out through the main body of the fermentation tank 1. After a long fermentation process, the internal temperature of the fermentation tank 1 becomes higher, or when the external temperature becomes higher, the internal temperature of the fermentation tank 1 rises. At this time, it is necessary to cool the liquid material inside the fermentation tank 1 to avoid problems such as deterioration of the liquid material. The turning drive device 5 is started to drive the turning component 4 to move up and down, turning the liquid material inside the fermentation tank 1, so that the liquid material inside the fermentation tank 1 can be mixed, thereby neutralizing the temperature of the liquid material. When the temperature inside the fermentation tank 1 continues to rise, through the cooperation of the exchange drive device 6 and the turning drive device 5, while the turning component 4 moves up and down, the liquid material in the built-in exchange cavity 23 of the temperature control component 2 is driven to flow into the external cooling cavity 21. The cooling plate 22 cools the liquid material in the external cooling cavity 21, and then the cooled liquid material in the external cooling cavity 21 flows back into the fermentation tank 1 again, so that the cooled liquid material is mixed with the liquid material inside the fermentation tank 1, thereby realizing the cooling treatment of the liquid material inside the fermentation tank 1. While the turning component 4 moves up and down, the cleaning component 3 is driven to move up and down to clean the colony population generated by fermentation on the inner wall of the fermentation tank 1, and it falls into the liquid material. Through the up and down movement of the turning component 4, the colony population is mixed with the liquid material.

[0035] Further, the turning drive device 5 includes a pushing motor 51, a mounting neck 52 and a mounting frame 53. The mounting neck 52 is located at the top of the fermentation tank 1. There is a mounting frame 53 above the mounting neck 52. The pushing motor 51 is located above the mounting frame 53. A pushing rod 54 is provided at the output end of the pushing motor 51. The other end of the pushing rod 54 passes through the mounting neck 52 and extends into the fermentation tank 1. There is a bearing 55 between the pushing rod 54 and the pushing motor 51. The outer side of the bearing 55 is fixedly connected to the pushing rod 54. The bottom of the pushing rod 54 is connected to the turning component 4. The output end of the pushing motor 51 in the turning drive device 5 drives the pushing rod 54 to move through the connection of the bearing 55. After the pushing rod 54 passes through the mounting neck 52, it drives the turning component 4 inside the fermentation tank 1 to move.

[0036] Further, a guiding sliding groove 551 is provided on the outer surface of the bearing 55, an angle adjusting driving block 56 is provided outside the bearing 55, the middle part of the angle adjusting driving block 56 is sleeved on the bearing 55, a sliding key 561 is provided in the middle part of the angle adjusting driving block 56, the guiding sliding groove 551 is in sliding fit with the sliding key 561, and the outside of the angle adjusting driving block 56 is in interference connection with the mounting bracket 53; by pushing the bearing 55 provided at the output end of the motor 51, when moving up and down, the guiding sliding groove 551 provided on the outer surface of the bearing 55 slides up and down along the sliding key 561 inside the angle adjusting driving block 56 for vertical guiding. When moving, the bearing 55 is located in the middle of the mounting bracket 53 and moves up and down to facilitate observing the position of the bearing 55, thereby judging the height of the material turning assembly 4 inside the fermentation tank 1. At the same time, when it is necessary to adjust the connection between the exchange driving device 6 and the material turning driving device 5, by rotating the angle adjusting driving block 56, the sliding key 561 in the middle of the angle adjusting driving block 56 cooperates with the guiding sliding groove 551, so that when the angle adjusting driving block 56 rotates, it can drive the outer ring of the bearing 55 to rotate. Further, the outer ring of the bearing 55 drives the push rod 54 at its bottom to rotate, thereby realizing the connection between the exchange driving device 6 and the material turning driving device 5.

[0037] Further, the material turning assembly 4 includes a plurality of turning plates 41, connecting brackets 42 and mounting brackets 43. One end of the mounting bracket 43 is connected to the bottom of the push rod 54, the turning plates 41 are located at the bottom of the other end of the mounting bracket 43, the turning plates 41 are connected by the connecting brackets 42, and the exchange driving device 6 is located at the bottom of the turning plates 41; through the turning plates 41 in the material turning assembly 4, they move up and down under the drive of the push rod 54. Further, a plurality of turning plates 41 connected by the connecting brackets 42 move up and down inside the fermentation tank 1 to perform up-and-down turning treatment on the liquid material inside the fermentation tank 1, and at the same time drive the exchange driving device 6 at the bottom of the turning plates 41 to move up and down.

[0038] Further, the cleaning component 3 includes a tank body cleaning vertical plate 31 and a cavity cleaning vertical plate 32. The tank body cleaning vertical plate 31 is arranged close to the inner wall of the fermentation tank 1, and the cavity cleaning vertical plate 32 is arranged close to the built-in exchange cavity 23. The tank body cleaning vertical plates 31 are arranged at intervals, and the intervals match the height of the built-in exchange cavity 23. Both the tank body cleaning vertical plate 31 and the cavity cleaning vertical plate 32 are connected to the material turning component 4. Through the cleaning of the inner wall of the fermentation tank 1 and the side wall of the built-in exchange cavity 23 by the tank body cleaning vertical plate 31 and the cavity cleaning vertical plate 32 in the cleaning component 3 respectively, when the material turning component 4 moves up and down, when the tank body cleaning vertical plate 31 and the cavity cleaning vertical plate 32 move upward together, after the cavity cleaning vertical plate 32 moves a height of one built-in exchange cavity 23, the material turning component 4 starts to move downward, and then after moving a height of one built-in exchange cavity 23 downward, the material turning component 4 moves upward again, and so on.

[0039] Further, a partition plate 211 is arranged inside the external cooling cavity 21. The partition plates 211 are arranged in a staggered manner on the inner and outer sides inside the external cooling cavity 21. The partition plate 211 close to the outer side is located on one side of the cooling plate 22 and is connected to the cooling plate 22. A throttling mesh plate 212 is arranged in the middle of the external cooling cavity 21. The throttling mesh plate 212 is horizontally arranged in the middle of the external cooling cavity 21. Through the partition plates 211 arranged in a staggered manner inside the external cooling cavity 21 to divide the external cooling cavity 21, when the liquid material flowing into the external cooling cavity 21 from the fermentation tank 1 flows in from above the external cooling cavity 21, the liquid material first enters the upper partition plate 211, and then flows downward back and forth along the staggered partition plates 211, so that the liquid material stays in the external cooling cavity 21 for a sufficient long time. And when the liquid material is at the partition plate 211 close to the cooling plate 22, the cooling plate 22 is used to cool the liquid material at this side of the partition plate 211. Then, after the liquid material passes through the throttling mesh plate 212, it flows into the bottom of the external cooling cavity 21.

[0040] Furthermore, a baffle 24 is provided between the external cooling chamber 21 and the internal exchange chamber 23. A cold liquid return hole 241 is provided at the bottom of the baffle 24, and the cold liquid return hole 241 enables the bottom of the external cooling chamber 21 to communicate with the bottom of the internal exchange chamber 23. A liquid material flow outlet 242 is provided above the baffle 24, and the liquid material flow outlet 242 enables the upper part of the external cooling chamber 21 to communicate with the upper part of the internal exchange chamber 23. The baffle 24 provided between the external cooling chamber 21 and the internal exchange chamber 23 prevents the liquid material from mixing randomly between the external cooling chamber 21 and the internal exchange chamber 23. First, the liquid material flows into the upper part of the external cooling chamber 21 from the liquid material flow outlet 242 provided above the baffle 24, then flows down along the alternately arranged partition plates 211, flows into the bottom of the external cooling chamber 21, and then flows back into the bottom of the internal exchange chamber 23 from the cold liquid return hole 241, so that the cooled liquid material is mixed with the relatively hot liquid material inside the fermentation tank 1.

[0041] Furthermore, a cold liquid exchange plate 231 is provided at the bottom inside the built-in exchange chamber 23. A cold liquid sealing plate 232 is provided at the bottom outside the cold liquid exchange plate 231. The cold liquid sealing plate 232 is disposed opposite to the cold liquid return hole 241. A switching groove 233 is provided above the cold liquid exchange plate 231. A carrier block 234 is provided above the switching groove 233. A liquid material exchange carrier plate 235 is provided above the inside of the built-in exchange chamber 23. A liquid material sealing plate 236 is provided at the bottom outside the liquid material exchange carrier plate 235. The liquid material sealing plate 236 is disposed opposite to the liquid material outlet 242. A card slot 237 is provided above the liquid material exchange carrier plate 235. The card slot 237 is located above one side of the switching groove 233. When the carrier block 234 moves into the card slot 237, the carrier block 234 locks the switching groove 233 and the card slot 237. When the cold liquid exchange plate 231 in the built-in exchange chamber 23 moves upward, the cooled liquid in the external cooling chamber 21 is pumped into the inside of the built-in exchange chamber 23, and at the same time drives the liquid material exchange carrier plate 235 on one side above it to move upward. When the liquid material sealing plate 236 outside the liquid material exchange carrier plate 235 moves upward, it blocks the liquid material outlet 242 above the baffle 24, making the upper part of the external cooling chamber 21 in a closed state. While the cold liquid exchange plate 231 continues to rise, at this time, the cold liquid sealing plate 232 outside the cold liquid exchange plate 231 moves away from the position of the cold liquid return hole 241, that is, the bottom of the external cooling chamber 21 is in an open state, so that the liquid flowing through the inside of the external cooling chamber 21 can be pumped into the built-in exchange chamber 23. When the cold liquid exchange plate 231 moves downward, the cooled liquid at the bottom of the built-in exchange chamber 23 is pushed outwards, so that the cooled liquid is mixed with the fermentation liquid at a higher temperature inside the fermentation tank 1. At the same time, it drives the liquid material exchange carrier plate 235 on one side above it to move, but at this time, the liquid material sealing plate 236 outside the liquid material exchange carrier plate 235 does not move out of the position of the liquid material outlet 242, and the upper part of the external cooling chamber 21 remains in a closed state. When the cold liquid exchange plate 231 moves downward, it pushes the liquid below it and will not push the liquid into the external cooling chamber 21 again. When the cold liquid exchange is completed and the temperature inside the fermentation tank 1 is not yet uniform, the angle of the push rod 54 is adjusted by the angle adjustment drive block 56, and then the push rod 54 drives the exchange drive device 6 to deflect, so that the carrier block 234 below it moves out of the position of the card slot 237. At this time, the switching groove 233 and the card slot 237 are in a separated state, that is, the carrier block 234 is in the switching groove 233 on the cold liquid exchange plate 231, only driving the cold liquid exchange plate 231 to move, and the liquid material exchange carrier plate 235 is located above the built-in exchange chamber 23 without moving. When the exchange drive device 6 continues to deflect and the carrier block 234 moves out of the switching groove 233, that is, the carrier block 234 does not drive the cold liquid exchange plate 231 and the liquid material exchange carrier plate 235 to move up and down, that is, the temperature control component 2 stops working.

[0042] Further, the exchange driving device 6 includes an exchange driving rod 61 and a vertical cylinder 62. The top of the exchange driving rod 61 is connected to the bottom of the rolling plate 41, the bottom of the exchange driving rod 61 is fixedly connected to the carrier block 234, the vertical cylinder 62 is sleeved outside the exchange driving rod 61, the vertical cylinder 62 is fixed to one side of the switching groove 233 away from the clamping groove 237, the vertical cylinder 62 extends into the switching groove 233, a slot 63 is formed on one side of the vertical cylinder 62, the slot 63 communicates with the inside of the switching groove 233, and the carrier block 234 slides inside the vertical cylinder 62; by connecting the exchange driving rod 61 in the exchange driving device 6 with the rolling plate 41, when the rolling plate 41 drives by the turning material driving device 5 and moves up and down, it drives the exchange driving rod 61 and the carrier block 234 below it to move up and down. When the angle of the push rod 54 is adjusted by the angle adjustment driving block 56, and then the push rod 54 drives the exchange driving device 6 to deflect, so that the carrier block 234 below it moves out of the position of the switching groove 233, the exchange driving rod 61 passes through the slot 63 and moves into the vertical cylinder 62. At this time, the exchange driving rod 61 and the carrier block 234 move up and down inside the vertical cylinder 62, and will not drive the cold liquid exchange plate 231 and the liquid material exchange carrier plate 235 to move.

[0043] Furthermore, a limiting plate is provided at the bottom of the built-in exchange chamber 23. A linkage plate 25 is provided above the limiting plate. The linkage plate 25 slides up and down along the inner wall of the built-in exchange chamber 23. A pull plate 251 is provided at the bottom of the cold liquid exchange plate 231. A follower plate 252 is provided above the linkage plate 25. The follower plate 252 is arranged corresponding to the pull plate 251. A wedge-shaped convex rib 253 is provided inside the pull plate 251. An inclined plate 254 is provided outside the follower plate 252. The inclined plate 254 is arranged corresponding to the wedge-shaped convex rib 253. The position of the linkage plate 25 is limited by the limiting plate provided at the bottom of the built-in exchange chamber 23. When the cold liquid exchange plate 231 moves upward, it drives the pull plate 251 at its bottom to move upward. The pull plate 251 cooperates with the inclined plate 254 through the wedge-shaped convex rib 253 provided inside it, so that an interference state exists between the pull plate 251 and the follower plate 252, that is, when the pull plate 251 moves upward, it can drive the follower plate 252 to move together. When the linkage plate 25 moves to the bottom of the built-in exchange chamber 23, the follower plate 252 cannot move further. The pull plate 251 continues to move. After the wedge-shaped convex rib 253 crosses the inclined plate 254, the pull plate 251 is separated from the follower plate 252, that is, the cold liquid exchange plate 231 continues to move upward, and the liquid cooled inside the external cooling chamber 21 is pumped into the bottom of the built-in exchange chamber 23. When the cold liquid exchange plate 231 moves downward, the pull plate 251 moves downward and contacts the follower plate 252, thereby pushing the follower plate 252 to move downward, and then the linkage plate 25 also moves downward, that is, the linkage plate 25 leaves the bottom of the built-in exchange chamber 23, making the bottom of the built-in exchange chamber 23 in an open state. The liquid cooled at the bottom of the built-in exchange chamber 23 can enter the fermentation tank 1. When the linkage plate 25 is restricted by the limiting plate, the linkage plate 25 cannot move further downward, while the cold liquid exchange plate 231 continues to move downward, and the pull plate 251 continues to move downward. By the wedge-shaped convex rib 253 provided inside it contacting the upper part of the follower plate 252, the follower plate 252 and the pull plate 251 are inclined to each other at this time until they cross each other between the pull plate 251 and the follower plate 252, and the pull plate 251 continues to move downward outside the follower plate 252 to complete the reset.

[0044] Working principle: When in use, the microbial fermentation of the liquid material is carried out through the main body of the fermentation tank 1. After a long fermentation process, the temperature inside the fermentation tank 1 rises, or when the external temperature rises, the temperature inside the fermentation tank 1 increases. At this time, it is necessary to cool the liquid material inside the fermentation tank 1 to avoid problems such as deterioration of the liquid material. The turning drive device 5 is started to drive the turning component 4 to move up and down, turning the liquid material inside the fermentation tank 1, so that the liquid material inside the fermentation tank 1 can be mixed, and then the temperature of the liquid material is neutralized. When the temperature inside the fermentation tank 1 continues to rise, through the cooperation of the exchange drive device 6 and the turning drive device 5, while the turning component 4 moves up and down, it drives the liquid material in the built-in exchange cavity 23 of the temperature control component 2 to flow into the external cooling cavity 21. Among them, the output end of the push motor 51 in the turning drive device 5 is connected through a bearing 55 to drive the push rod 54 to move. After the push rod 54 passes through the mounting neck 52, it drives the turning component 4 inside the fermentation tank 1 to move. The bearing 55 provided at the output end of the push motor 51 slides vertically along the sliding key 561 inside the angle adjustment drive block 56 during the up and down movement. When moving, the bearing 55 moves up and down in the middle of the mounting frame 53 to facilitate observing the position of the bearing 55, and then judging the height of the turning component 4 inside the fermentation tank 1. At the same time, when it is necessary to adjust the connection between the exchange drive device 6 and the turning drive device 5, by rotating the angle adjustment drive block 56, the sliding key 561 in the middle of the angle adjustment drive block 56 cooperates with the guiding chute 551, so that when the angle adjustment drive block 56 rotates, it can drive the outer ring of the bearing 55 to rotate, and then the outer ring of the bearing 55 drives the push rod 54 at its bottom to rotate, and then the connection between the exchange drive device 6 and the turning drive device 5;

[0045] Then, the exchange drive rod 61 in the exchange drive device 6 is connected to the turning plate 41. When the turning plate 41 is driven by the turning drive device 5 to move up and down, it drives the exchange drive rod 61 and the carrier block 234 below it to move up and down. When the angle of the push rod 54 is adjusted through the angle adjustment drive block 56, and then the push rod 54 drives the exchange drive device 6 to deflect, so that the carrier block 234 below it moves out of the position of the switching groove 233, the exchange drive rod 61 passes through the slot 63 and moves into the vertical cylinder 62. At this time, the exchange drive rod 61 and the carrier block 234 move up and down in the vertical cylinder 62 and do not drive the cold liquid exchange plate 231 and the liquid material exchange carrier plate 235 to move;

[0046] The cooling plate 22 cools the liquid in the external cooling chamber 21. Then, the cooled liquid in the external cooling chamber 21 flows back into the fermentation tank 1 again, so that the cooled liquid is mixed with the liquid inside the fermentation tank 1, thereby realizing the cooling treatment of the liquid inside the fermentation tank 1. Among them, the external cooling chamber 21 is divided by the partition plates 211 arranged crosswise inside the external cooling chamber 21. When the liquid flowing into the external cooling chamber 21 from the fermentation tank 1 flows in from above the external cooling chamber 21, the liquid first enters the upper partition plate 211, and then flows downward back and forth along the crosswise arranged partition plates 211, so that the liquid stays in the external cooling chamber 21 for a long enough time. And when it is near the partition plate 211 on the side of the cooling plate 22, the cooling plate 22 cools the liquid at this side of the partition plate 211. Then, after the liquid passes through the throttle mesh plate 212, it flows into the bottom of the external cooling chamber 21. The baffle 24 arranged between the external cooling chamber 21 and the internal exchange chamber 23 prevents the liquid from mixing randomly between the external cooling chamber 21 and the internal exchange chamber 23. First, the liquid flows into the upper part of the external cooling chamber 21 from the liquid outlet 242 arranged above the baffle 24, then flows down along the crosswise arranged partition plates 211, and then flows into the bottom of the external cooling chamber 21, and then from the cold liquid return hole 241, so that the cooled liquid flows back into the bottom of the internal exchange chamber 23 from the bottom of the external cooling chamber 21, realizing the mixing of the cooled liquid and the hotter liquid inside the fermentation tank 1. When the cold liquid exchange plate 231 in the internal exchange chamber 23 moves upward, it pumps the cooled liquid in the external cooling chamber 21 into the internal exchange chamber 23, and at the same time drives the liquid exchange carrier plate 235 on one side above it to move upward. When the liquid sealing plate 236 outside the liquid exchange carrier plate 235 moves upward, it seals the liquid outlet 242 above the baffle 24, making the upper part of the external cooling chamber 21 in a closed state. And when the cold liquid exchange plate 231 continues to rise, at this time, the cold liquid sealing plate 232 outside the cold liquid exchange plate 231 moves away from the position of the cold liquid return hole 241, that is, the bottom of the external cooling chamber 21 is in an open state, so that the liquid flowing through the external cooling chamber 21 can be pumped into the internal exchange chamber 23. When the cold liquid exchange plate 231 moves downward, it pushes the cooled liquid at the bottom of the internal exchange chamber 23 to the outside, so that the cooled liquid is mixed with the fermentation liquid at a higher temperature inside the fermentation tank 1, and at the same time drives the liquid exchange carrier plate 235 on one side above it to move. But at this time, the liquid sealing plate 236 outside the liquid exchange carrier plate 235 does not move out of the position of the liquid outlet 242, and the upper part of the external cooling chamber 21 is still in a closed state. And when the cold liquid exchange plate 231 moves downward, it pushes the liquid below it and will not push the liquid back into the external cooling chamber 21 again;When the internal temperature of the fermentation tank 1 has not yet been uniform after the cold liquid exchange is completed, the angle of the push rod 54 is adjusted by the angle adjustment drive block 56, and then the push rod 54 drives the exchange drive device 6 to deflect, so that the carrier block 234 below it moves out of the position of the card slot 237. At this time, the switching slot 233 and the card slot 237 are in a separated state, that is, the carrier block 234 is in the switching slot 233 on the cold liquid exchange plate 231, only driving the cold liquid exchange plate 231 to move, and the liquid material exchange carrier plate 235 is located above the built-in exchange cavity 23 without moving. When the exchange drive device 6 continues to deflect and the carrier block 234 moves out of the switching slot 233, that is, the carrier block 234 does not drive the cold liquid exchange plate 231 and the liquid material exchange carrier plate 235 to move up and down, that is, the temperature control component 2 stops working;

[0047] While the material turning component 4 moves up and down, it drives the cleaning component 3 to move up and down to clean the colony population generated by fermentation on the inner wall of the fermentation tank 1 and let it fall into the liquid material. Through the up and down movement of the material turning component 4, the colony population is mixed with the liquid material; among them, when the angle of the push rod 54 is adjusted by the angle adjustment drive block 56, and then the push rod 54 drives the exchange drive device 6 to deflect, so that the carrier block 234 below it moves out of the position of the switching slot 233, the exchange drive rod 61 passes through the slotted opening 63 and moves into the vertical cylinder 62. At this time, the exchange drive rod 61 and the carrier block 234 move up and down in the vertical cylinder 62, and do not drive the cold liquid exchange plate 231 and the liquid material exchange carrier plate 235 to move. The material turning drive device 5 only drives the cleaning component 3 and the material turning component 4 to operate. Through the tank body cleaning vertical plate 31 and the cavity cleaning vertical plate 32 in the cleaning component 3, the inner wall of the fermentation tank 1 and the side wall of the built-in exchange cavity 23 are respectively cleaned. When the material turning component 4 moves up and down, when the tank body cleaning vertical plate 31 and the cavity cleaning vertical plate 32 move up together, after the cavity cleaning vertical plate 32 moves a height of the built-in exchange cavity 23, the material turning component 4 starts to move down, and then after moving down a height of the built-in exchange cavity 23, the material turning component 4 moves up again, and so on. Through the turning plate 41 in the material turning component 4, it moves up and down driven by the push rod 54. Furthermore, a number of turning plates 41 connected by the connecting bracket 42 move up and down inside the fermentation tank 1 to turn the liquid material inside the fermentation tank 1 up and down, and at the same time drive the exchange drive device 6 at the bottom of the turning plate 41 to move up and down
