Description

Technical Field

[0001] The utility model relates to the technical field of biological fermentation, in particular to a fermentation tank suitable for small batch fermentation. Background Art

[0002] Microbial fermentation refers to the phenomenon of large-scale production and accumulation of specific metabolites by microorganisms. Fermentation can be divided into several types according to the physiological characteristics, nutritional requirements, culture medium properties and fermentation production methods of the microorganisms. Batch fermentation refers to a microbial culture method in which a limited amount of nutrients are put into a closed system, and then a small amount of microbial strains are cultured to allow the microorganisms to grow and reproduce, completing only one growth cycle under specific conditions. In this process, except for continuous ventilation (aerobic fermentation) and the addition of acid and alkali solutions to adjust the pH of the fermentation liquid, there is no other material exchange with the outside world. The culture medium is added at one time and the product is harvested at one time. It is a fermentation method that is currently widely used. Due to the widespread use of batch fermentation, optimization of fermentation equipment is also necessary.

[0003] For example, a fermentation tank is disclosed in the Chinese utility model patent with the announcement number CN218026055U. Although the above-mentioned prior art can quickly take out the fermented product and can regularly turn over the product in the fermentation tank to improve the fermentation efficiency, after the fermentation inside the fermentation tank is completed and the fermented products are taken out, a lot of fermented products will remain on the inner wall of the fermentation tank and the stirring component. Such residues will not only cause waste, because some fermented products are relatively expensive, but also cause cleaning difficulties, because the inside of the fermentation tank needs to be thoroughly cleaned, which increases the cleaning time and affects the work efficiency. Therefore, it is necessary to design a fermentation tank that can collect a certain amount of residue on the inner wall of the fermentation tank when collecting the fermented products. Utility Model Content

[0004] In order to solve the technical problem that a lot of fermented materials will remain on the inner wall of the fermentation tank after the fermentation is completed and collected, causing waste, the utility model provides a fermentation tank suitable for small batch fermentation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a stirring component, a collecting component and a vibrating component. When the fermentation in the fermentation tank is completed and the residue is collected, the rotation of the stirring component will scrape the residue on the inner wall of the tank body onto the stirring component. The collecting component will continue to descend due to the reduction of objects inside the tank body, and the residue scraped off the stirring component will be scraped downward, and finally fall on the bottom of the tank body to be collected. The vibrating component can vibrate the inner wall of the tank body when the stirring component rotates, so that the residue can quickly roll to the bottom of the tank body to be collected. In this way, after the fermentation in the tank body is completed, the residue attached to the inner wall can also be collected, thereby avoiding waste and difficulty in cleaning.

One end of the stirring rod 201 passes through the tank body 1 and extends to the outside thereof. A servo motor 7 is provided on one side of the tank body 1, and one end of the stirring rod 201 is fixedly installed with the output end of the servo motor 7. The first scraper 202 and the second scraper 6 rotate along the stirring rod 201 to scrape and collect the inner wall of the tank body 1.

[0028] Combination Figure 2 and Figure 3 The collecting assembly includes a floating plate 301 slidably mounted on the stirring rod 201, collecting plates 302 arranged on both sides of each first scraper 202, a first fixed plate 303 fixedly mounted on one side of each collecting plate 302, and a second fixed plate 304 fixedly mounted on one end of each first fixed plate 303, one end of each second fixed plate 304 is fixedly mounted on the floating plate 301, a plurality of limiting strips 8 are fixedly mounted on the circumferential surface of the stirring rod 201, a plurality of limiting grooves are opened on one side of the floating plate 301, and when the floating plate 301 descends, the collecting plate 302 will be in contact with the first scraper 202 to descend, and the residue on the first scraper 202 will be scraped off and collected.

[0029] Combination Figure 2-Figure 4 A rotating groove is provided on one side of each second scraper 6, and the vibration assembly includes a rotating shaft 401 rotatably installed inside each rotating groove and a rotating column 402 sleeved on each rotating shaft 401. A plurality of top sheets 9 are fixedly installed on the inner wall of the tank body 1. When the rotating column 402 contacts the top sheet 9, it will be lifted up by the top sheet 9. When separated, it will collide with the inner wall of the tank body 1 to generate vibration.

[0030] Combination Figure 1The support assembly includes a fixing ring 501 fixedly mounted on the outer surface of the tank body 1, a limiting ring 502 arranged on one side of the fixing ring 501 and mounted on the outer surface of the tank body 1, and a plurality of supporting columns 503 fixedly installed on one side of the limiting ring 502. The supporting columns 503 and the limiting ring 502 can be removed from the tank body 1 to facilitate the transportation of the tank body 1.

[0031] The implementation principle of a fermentation tank suitable for small batch fermentation in the embodiment of the present application is as follows: when the tank body 1 is fermenting, starting the servo motor 7 can allow the stirring rod 201 to drive the connecting plate 203, the first scraper 202 and the second scraper 6 to rotate inside the tank body 1 to stir the fermented material. According to the required degree of stirring, a plate for stirring can be added between the first scraper 202 and the stirring rod 201. The thickness of this plate is the same as that of the first scraper 202, which is convenient for the two collecting plates 302 to contact it. When the fermentation is completed and collected, the servo motor 7 continues to start. As the fermented material inside the tank body 1 decreases, the floating plate 301 will continue to descend. At the same time, the residue attached to the inner wall of the tank body 1 will also be scraped onto the first scraper 202. The descent of the floating plate 301 will allow the second fixed plate 304 to drive the first fixed plate 303 and the collecting plate 302 descend together, and the collecting plate 302 descends in close contact with the two sides of the first scraper 202, and the residue scraped off from the first scraper 202 will be scraped downward again. When it scrapes to the bottom, the residue will fall on the inclined inner wall of the tank body 1 and move toward the discharge port at the bottom to be collected again. The residue at the inclined position will also be scraped and collected by the second scraper 6, and flow to the discharge port along the inclined angle. During the scraping process of the second scraper 6, after the rotating column 402 contacts the top sheet 9, it will briefly lift a part of the second scraper 6. After separating from the top sheet 9, it will hit the inner wall of the tank body 1 under the action of the downward pressure of the second scraper 6 to generate vibration, so that the residue on the inclined surface can be collected by sliding down under the vibration. In this way, after the fermentation of the tank body 1 is completed, the residue attached to the inner wall can also be collected, thereby avoiding waste and subsequent cleaning difficulties.
