DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0026] Embodiment 1

[0027] According to Figures 1-5As shown, this embodiment proposes a low-temperature microbial fermentation system for preserved fruits, including a fermentation tank 1, a top cover 2, a bracket 3 and a mesh fermentation cylinder 4. In the present invention, the fermentation tank 1 is a fermentation tank 1 with an active temperature regulation system. The active temperature regulation system is composed of a heating module, a cooling module, a temperature monitoring module and a central control chip. The temperature monitoring module is used to monitor the temperature of the fermentation liquid in the fermentation tank 1 in real time. When the monitored temperature is lower than the temperature required for low-temperature fermentation, the monitoring signal of the temperature monitoring module is sent to the central control chip, and the central control chip controls the heating module to heat until the temperature of the fermentation liquid reaches the required value. After the temperature of the fermentation liquid reaches the required value, the heating module is kept warm. When the fermentation liquid in the fermentation tank 1 needs to be cooled, the central control chip controls the heating module to be turned off, and the cooling module is started to heat the fermentation liquid. The liquid temperature is reduced to the required value, so as to realize active temperature regulation of the fermentation tank 1, a top cover 2 is provided above the fermentation tank 1, an opening and closing control mechanism is provided on the side wall of the fermentation tank 1, the top cover 2 is connected with the opening and closing control mechanism, a driving cylinder 5 is provided on the top cover 2, and a bracket 3 is provided at the output end of the driving cylinder 5, a first rotating seat 6 and a second rotating seat 7 are provided inside the bracket 3, one end of the first rotating seat 6 and the second rotating seat 7 are both rotatably connected to the bracket 3, a mesh fermentation cylinder 4 is provided between the first rotating seat 6 and the second rotating seat 7, and the mesh fermentation cylinder 4 is provided with a plurality of groups, one end of the plurality of groups of mesh fermentation cylinders 4 extends out of one side of the second rotating seat 7 and is provided with a sealing cover 9, a sealing frame 10 is provided on the outer side of the upper end of the bracket 3, and the size of the sealing frame 10 is adapted to the internal size of the upper end of the fermentation tank 1. In the present invention, the sealing frame 10 can seal the upper end of the fermentation tank 1 when the driving cylinder 5 lifts the bracket 3 so that the mesh fermentation cylinder 4 is separated from the fermentation liquid in the fermentation tank 1, thereby ensuring a stable aerobic or anaerobic environment in the fermentation tank 1. In addition, due to the setting of the sealing frame 10, the heat of the driving motor 12 can be dissipated by opening the end cover and using the heat dissipation port 18 when the driving motor 12 is working. The sealing frame 10 cooperates with the top cover 2 to provide a double sealing effect during the fermentation process of the fermentation system, thereby stabilizing the fermentation quality.

[0028] When the candied fruit low-temperature microbial fermentation system of the present invention is fermenting, the support 3 is lifted by the driving cylinder 5, so that the mesh fermentation cylinder 4 is moved out of the fermentation tank 1. Then, the candied fruit raw materials are put into the mesh fermentation cylinder 4. Then, the driving cylinder 5 controls the support 3 to reset, so that the mesh fermentation cylinder 4 is immersed in the soaking liquid inside the fermentation tank 1. When stirring is required during the process, the mesh fermentation cylinder 4 is synchronously rotated by controlling the rotation of the first rotating seat 6 and the second rotating seat 7. Since the mesh fermentation cylinder 4 is horizontal, the candied fruit raw materials will not completely fill the inside of the mesh fermentation cylinder 4 during filling, and there is a turning space left inside the mesh fermentation cylinder 4. Therefore, when the mesh fermentation cylinder 4 rotates, the candied fruit raw materials turn inside the mesh fermentation cylinder 4 to achieve mixing. When air bubbles accumulate in the candied fruit raw materials in the mesh fermentation cylinder 4, the driving cylinder 5 can be used again to lift the support 3 to ensure that the mesh fermentation cylinder 4 is lifted from the soaking liquid inside the fermentation tank 1. Then, the first rotating seat 6 and the second rotating seat 7 are controlled to rotate again so that the mesh fermentation cylinder 4 rotates synchronously, and defoaming is carried out by rotation.

[0029] The support 3 includes a top plate 301 and end head plates 302. The top plate 301 is installed at the output end of the driving cylinder 5. End head plates 302 are provided on both sides of the bottom of the top plate 301. The sealing frame 10 is arranged outside the top plate 301. A main shaft 11 is provided on the first rotating seat 6. A driving motor 12 is provided on the top of the support 3. The output end of the driving motor 12 is connected to the main shaft 11 through a linkage mechanism. A sealing shell 13 is provided on the side wall of a group of end head plates 302 near the driving motor 12. The main shaft 11 is located inside the sealing shell 13. The linkage mechanism includes synchronous pulleys 14 and a synchronous belt 15. Synchronous pulleys 14 are provided on both the output end of the driving motor 12 and the main shaft 11, and a synchronous belt 15 is connected between the two synchronous pulleys 14. When the first rotating seat 6 and the second rotating seat 7 of the present invention rotate synchronously, by starting the driving motor 12, the main shaft 11 rotates under the transmission of the synchronous pulleys 14 and the synchronous belt 15 of the linkage mechanism, and the main shaft 11 drives the first rotating seat 6 to rotate synchronously. Since the first rotating seat 6, multiple groups of mesh fermentation cylinders 4 and the second rotating seat 7 are connected together, the three rotate synchronously.

[0030] The opening and closing control mechanism includes a support 16 and an opening and closing cylinder 17. Supports 16 are provided on both side walls of the fermentation tank 1. An opening and closing cylinder 17 is provided on the support 16. The output end of the opening and closing cylinder 17 is connected to the bottom of both ends of the top cover 2. When the top cover 2 of the present invention is opened and closed, the opening and closing of the top cover 2 is controlled by starting the opening and closing cylinder 17.

[0031] A heat dissipation port 18 is provided on the top cover 2. The position of the heat dissipation port 18 is adapted to the position of the driving motor 12. An end cover is provided on the heat dissipation port 18. The setting of the heat dissipation port 18 can allow heat to be discharged from the heat dissipation port 18 by opening the end cover when the driving motor 12 is running.

[0032] By setting the candied fruit low-temperature microbial fermentation system to be composed of a fermentation tank 1, a top cover 2, a bracket 3, a mesh fermentation cylinder 4, etc., the candied fruit raw materials are loaded through multiple mesh fermentation cylinders 4 and then soaked in the fermentation tank 1. Loading the candied fruit raw materials into multiple mesh fermentation cylinders 4 can effectively avoid the problem that excessive accumulation of raw materials affects the fermentation quality; in the present invention, multiple mesh fermentation cylinders 4 are all connected to a first rotating seat 6 and a second rotating seat 7, and the mesh fermentation cylinder 4 can rotate synchronously with the first rotating seat 6 and the second rotating seat 7 to realize the turning of the candied fruit raw materials inside, ensuring the uniform mixing of the candied fruit raw materials; the telescopic movement of the driving cylinder 5 of the present invention can synchronously drive the overall structure on the bracket 3 to lift. When the bubbles accumulated on the surface of the candied fruit raw materials in the mesh fermentation cylinder 4 need to be cleaned, the bracket 3 is lifted to lift the mesh fermentation cylinder 4 to defoam, ensuring the fermentation quality of the candied fruit raw materials.

A mesh fermentation cylinder 4 is provided between the first rotating seat 6 and the second rotating seat 7. There are multiple groups of the mesh fermentation cylinders 4. Partition plates 8 are provided inside multiple groups of the mesh fermentation cylinders 4. One end of multiple groups of the mesh fermentation cylinders 4 extends out of one side of the second rotating seat 7 and is provided with a sealing cover 9. A sealing frame 10 is provided outside the upper end of the bracket 3. The size of the sealing frame 10 is adapted to the internal size of the upper end of the fermentation tank 1.

[0035] A partition plate 8 is provided inside the mesh fermentation cylinder 4. By providing the partition plate 8, when the mesh fermentation cylinder 4 is flipped, the partition plate 8 can be used to control the candied fruit raw materials to be flipped to a high place and then fall, improving the mixing effect of the candied fruit inside the mesh fermentation cylinder 4. The mesh fermentation cylinder 4 includes a first end 401, a second end 402, and an intermediate mesh cylinder body 403. One end of the first end 401 is provided with the intermediate mesh cylinder body 403. One end of the intermediate mesh cylinder body 403 is provided with a transition cylinder body 404.

In the present invention, the feeding method can be to load candied fruit raw materials into the intermediate mesh cylinder body 403 through the feeding pipe from the second end 402. By opening the sealing cover 9 on the second end 402, it is possible to take out the candied fruit from the second end 402 to detect the fermentation state of the candied fruit. In the present invention, the opening and closing plate is hingedly connected to the body of the intermediate mesh cylinder body 403 and is fixed by a fixing structure (which can be a bolt or others). By releasing the fixing of the opening and closing plate by the fixing structure, the opening and closing plate can be flipped open. In the present invention, by opening the opening and closing plate, the fermented candied fruit in the intermediate mesh cylinder body 403 can be taken out, or candied fruit raw materials can be loaded into the intermediate mesh cylinder body 403 by opening the opening and closing plate.
