[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-4 The present embodiment provides a composite microbial fermentation agent production device, including a tank body 1, wherein the tank body 1 is used to contain materials required for the fermentation reaction such as multiple microbial strains, water, pH regulators and other auxiliary materials, so as to produce liquid composite microbial fermentation products; a hollow stirring shaft 16 is arranged inside the tank body 1, a stirring motor 3 is arranged at the bottom, and the rotating output shaft of the stirring motor 3 extends into the tank body 1 and is connected to the stirring shaft 16. At the same time, a discharge pipe 13 and a plurality of supporting legs 7 are arranged at the bottom of the tank body 1, and the top of the supporting legs 7 is connected to the bottom of the tank body 1.

[0028] Furthermore, a limiting ring 8 is provided on one side of the supporting foot 7 , and a plurality of air outlet holes 9 are opened on the outer wall surface of the stirring shaft 16 , and a stirring frame 19 is connected thereto.

[0029] The side of the stirring frame 19 away from the stirring shaft 16 is connected to a wall scraper head 18. Figure 5 As shown, both ends of the scraper head 18 are wedge-shaped structures, and the shape matches the inner wall surface of the tank body 1. As in this embodiment, the scraper head 18 can be an arc-shaped structure. At the same time, there is a gap between the scraper head 18 and the inner wall surface of the tank body 1, and the distance of the gap is 3-5mm. Therefore, the scraper head 18 can fully scrape off the residues adhered to the inner wall of the tank body.

[0030] At the same time, the outer wall surface of the stirring shaft 16 is also connected to the first stirring blade 2, the second stirring blade 10 and the third stirring blade 11, and the first stirring blade 2, the second stirring blade 10 and the third stirring blade 11 are arranged from high to low, so that the materials at different positions in the tank body 1 can be fully stirred and mixed.

[0031] The top of the stirring shaft 16 extends out from the tank body 1 and is rotatably connected to the bottom of a gas storage tank 17 located outside the tank body 1 and used to store air or oxygen. At the same time, the interior of the stirring shaft 16 is connected to the interior of the gas storage tank 17. For example, in this embodiment, a bearing may be provided at the bottom of the gas storage tank 17, and the top of the stirring shaft 16 is connected to the bearing. When the stirring shaft 16 rotates, the gas storage tank 17 remains stationary.

[0032] Furthermore, an oxygen concentration detection sensor 15 and / or a temperature sensor 14 are installed on the stirring frame 19, and the oxygen concentration detection sensor 15 and the temperature sensor 14 are respectively used to obtain the oxygen concentration data and the temperature data in the tank body 1 in real time. At the same time, a feeding pipe 12 is provided on the top of the tank body 1, and the materials required for the fermentation reaction can be added into the tank body 1 through the feeding pipe 12.

[0033] During operation, the stirring motor 3 is started, and the first stirring blade 2, the second stirring blade 10, the third stirring blade 11, and the stirring frame 19 are controlled to rotate synchronously by rotating the output shaft thereof, so as to stir the material in the tank body 1 and make it mixed evenly. At the same time, the scraper head 18 at the end of the stirring frame 19 can scrape off the attachments on the inner wall of the tank body 1 to avoid residual attachments, and further avoid contamination of different batches of production materials. At the same time, after the attachments are scraped off, the newly added materials can be better mixed evenly inside the equipment, which is beneficial to the growth and metabolism of microorganisms, thereby improving the overall efficiency of fermentation.

[0034] Furthermore, an air outlet 9 is provided on the surface of the stirring shaft 16. When the stirring shaft 16 rotates, the gas storage tank 17 does not rotate, and the gas in the storage tank 17 can enter the tank body 1 through the air outlet 9 and be evenly dispersed in the fermentation material to meet the oxygen content requirement of aerobic fermentation. Specific embodiment 2:

[0036] The only difference between this embodiment and the first embodiment is that a controller 4 is provided on the front of the tank body 1, a display screen 5 is provided on the front of the controller 4, an operation button 6 is provided on the front of the controller 4, and the controller 4 is electrically connected to the stirring motor 3 and the solenoid valve of the gas storage tank 17, thereby, the start and stop of the stirring motor 3 and the opening and closing of the solenoid valve can be controlled by the operation button 6.

[0037] For example, when the oxygen concentration detection sensor 15 detects that the oxygen concentration in the tank body 1 is lower than a threshold value, the solenoid valve of the gas storage tank 17 is opened by operating the button 6, and the gas in the gas storage tank 17 enters the stirring shaft 16 and enters the material through the air outlet 9. Specific embodiment three:

[0039] The only difference between this embodiment and embodiment one or two is that the composite microbial fermentation agent production equipment also includes: a plurality of support frames 21, which are located outside the tank body 1 and connected to the gas storage tank 17 at one end and the tank body 1 at the other end, so as to support and position the gas storage tank 17.

[0040] At the same time, microbial fermentation is sensitive to temperature, and a suitable temperature range can significantly promote the growth and metabolism of microorganisms. Therefore, a heating tube 20 electrically connected to the controller 4 is provided inside the tank body 1. When the temperature sensor 14 detects that the temperature inside the tank body 1 is lower than the threshold, the heating tube 20 is started by operating the button 6 to heat the inside of the tank body 1, so as to accurately adjust the temperature inside the tank body 1 and ensure that the fermentation process is always carried out under the optimal temperature conditions to avoid large temperature fluctuations from having an adverse effect on the fermentation.

[0041] To summarize, the present application avoids residual attachments by scraping off the attachments on the inner wall of the tank body, thereby further preventing the attachments from contaminating different batches of production materials. At the same time, after the attachments are scraped off, the newly added materials can be better mixed evenly inside the equipment, which is beneficial to the growth and metabolism of microorganisms. At the same time, gas is supplied to the tank body through a gas storage tank, and the temperature inside the tank body is adjusted through a heating pipe to ensure that the fermentation process is always carried out under the optimal temperature conditions, thereby avoiding large temperature fluctuations from having an adverse effect on the fermentation.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
