Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation, and particularly relates to a fermentation liquid stirring tank device. Background Art

[0002] Fermentation is to generate a series of fermentation products through fermentation between bacteria and fermentation liquid under specific conditions such as pressure, temperature, humidity, etc. For example, active peptides and other fermentation products are produced through fermentation by lactic acid live bacteria and yeast live bacteria.

[0003] And fermentation products such as active peptides can improve the intestinal microecology of animals. Therefore, the fermentation liquid obtained after fermentation by the fermentation method contains a large amount of nutrients beneficial to animals, and thus can be widely used in the aquaculture industry. For example, the fermentation products are used as feed additives and added to feed, which can improve the intestinal microecology of animals and achieve the improvement of aquaculture effects.

[0004] During the fermentation process, hierarchical fermentation is often required. Therefore, during fermentation, the fermentation liquid needs to be continuously transported and the fermentation liquid needs to be supplemented to continue fermentation to ensure sufficient nutrients and fermentation space for the rapidly multiplying bacteria.

[0005] Therefore, during the fermentation process, how to quickly divert the fermentation materials, supplement the fermentation nutrient solution, continue fermentation, and quickly divert the fermentation materials after fermentation is of great significance for increasing the fermentation effect and improving the fermentation yield. However, the existing fermentation equipment is difficult to achieve rapid diversion of the fermentation materials and continue fermentation.

[0006] During the fermentation process, especially in the diversion process of large fermentation tanks, it is extremely slow, resulting in a slow fermentation process and low fermentation productivity. Summary of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a fermentation liquid stirring tank device.

[0018] The stirring motor is fixedly installed on the tank top cover.

[0019] Preferably, the transverse cross-sectional shape of the material passing plate is circular;

If the eighth fermentation tank is synchronized with the first fermentation tank, the materials in the eighth fermentation tank are diverted to the seventh fermentation tank until the last empty fermentation tank), pump them into the second fermentation tank. At this time, according to the existing vacuum pumping method, the second fermentation tank is pre-evacuated (the method is to use a vacuum pump connected to the vacuum pumping pipe on the second fermentation tank and open the valve on the vacuum pumping pipe) to form a vacuum, and then open the valve on the material connection pipe between the two to achieve pumping.

[0040] Embodiment 1

[0041] As Figures 1-5 shown, a fermentation broth stirring tank device includes a multi-stage fermentation tank stirring mechanism; the multi-stage fermentation tank stirring mechanism includes a plurality of fermentation tanks connected in sequence. Specifically, the multi-stage fermentation tank stirring mechanism includes a first fermentation tank 1, a second fermentation tank 2, a third fermentation tank 3, a fourth fermentation tank 4, a fifth fermentation tank 5, a sixth fermentation tank 6, a seventh fermentation tank 7 and an eighth fermentation tank 8.

[0042] During the working process, when the material is in the first fermentation tank 1 and ferments for a period of time, a part of the material is diverted to the second fermentation tank 2, and after supplementing the fermentation broth, the fermentation continues, and so on to achieve continuous fermentation. During the fermentation process, if the material in the third fermentation tank 3 has been fermented, the material can be directly discharged from the third fermentation tank at this time.

[0043] Specifically, the connection mode of the above-mentioned first fermentation tank 1 to the eighth fermentation tank 8 is as follows: the discharge end of the fermentation tank (the discharge end of the fermentation tank is a pipeline connected to the lower end of the tank) is connected to the feed end through a material pipe 9 (the feed end of the fermentation tank is a pipeline connected to the upper end of the tank). A valve is installed on the material pipe 9.

[0044] Moreover, a vacuum pumping pipe 92 is connected to the upper end of the fermentation tank, and a lower discharge pipe 91 is connected to the lower end of the fermentation tank.

[0045] During the working process, for example, pump half of the material in the first fermentation tank 1 (a pump feeding pipe is assembled and connected to the upper end of the first fermentation tank 1 to realize pumping of the primary material, or pump the material through the pump feeding pipe assembled and connected to the upper end of the eighth fermentation tank 8 to realize synchronous fermentation and synchronous diversion of the material. If the eighth fermentation tank 8 is synchronous with the first fermentation tank 1, divert the material in the eighth fermentation tank 8 to the seventh fermentation tank 7 until the last empty fermentation tank) into the second fermentation tank 2. At this time, according to the existing vacuum pumping method, pre-vacuum the second fermentation tank 2 (the method is to use a vacuum pump connected to the vacuum pumping pipe 92 on the second fermentation tank 2 and open the valve on the vacuum pumping pipe 92) to form a vacuum, and then open the valve on the material pipe 9 connecting the two to realize pumping.

[0046] Similarly, the second fermentation tank 2 can be pumped into the third fermentation tank 3.

[0047] The first fermentation tank 1 continues to supplement the nutrient solution and continue to ferment. Through the above method, continuous fermentation is achieved.

[0048] After fermentation, the discharging method is: open the valve on the lower discharge pipe 91 to realize discharging.

[0049] Embodiment 2

[0050] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, during the fermentation process, in order to avoid a large amount of materials with large particle sizes such as agglomerated materials from settling to the bottom of the tank, resulting in uneven distribution of the fermentation nutrient materials, a stirring mechanism 10 is assembled and connected to the above-mentioned fermentation tank; the stirring mechanism 10 includes a stirring motor 101 installed on the fermentation tank.

[0051] Specifically, similar to the existing method, a tank top cover is installed on the tank opening of the above-mentioned fermenter; the stirring motor 101 is fixedly installed on the tank top cover. The stirring motor 101 is assembled and connected with a long stirring shaft 102 (the method is that the output end of the stirring motor 101 is installed with the long stirring shaft 102 through a coupling, and the long stirring shaft 102 is rotatably connected to the tank top cover). A plurality of material passing plates 103 (the material passing plates 103 are circular plates made of stainless steel) are fixedly connected in the fermenter at intervals up and down. A relatively independent stirring chamber is formed between adjacent material passing plates 103 and the inner side wall of the tank body. A plurality of stirring members are fixedly connected to the long stirring shaft 102 and are respectively located in the stirring chambers.

[0052] At the same time, a plurality of strip-shaped material openings 1031 are formed on the material passing plates 103, and the material passes through the strip-shaped material openings 1031, and the massive materials are intercepted on the material passing plates 103; the size of the strip-shaped material openings 1031 is: the width of the strip-shaped material openings 1031 on the material passing plates 103 decreases in turn from the upper material passing plate 103 to the lower material passing plate 103.

[0053] During the fermentation reaction process, agglomeration will occur along with stirring, and the materials with large particle sizes will be gradually dispersed and refined and dissolved into the material system, avoiding the precipitation of agglomerated and large-particle materials at the bottom of the tank due to their large weight, resulting in uneven distribution of nutrients.

[0054] The long stirring shaft 102 is rotatably connected to the material passing plate 103. The specific method is: a bearing is installed at the central part of the material passing plate 103, and the long stirring shaft 102 is rotatably connected to the bearing.

[0055] At the same time, the stirring member includes a plurality of toothed plates 104, and a plurality of toothed protrusions 1041 are integrally formed on the outer side wall of the toothed plate 104 at intervals up and down. With this shape design of the toothed plate 104, during the stirring process, while the material is fully stirred through the toothed protrusion 1041 structure, the material is refined due to the toothed protrusion 1041 structure.

[0056] At the same time, long strip-shaped through holes 105 are formed vertically on the toothed plate 104, and a plurality of inclined stirring plates 106 are fixedly connected in the long strip-shaped through holes 105 at intervals up and down. The shape of the inclined stirring plate 106 is rectangular, and the purpose is also to increase the refinement efficiency of the material, so as to fully crush the agglomerated and large-particle substances and increase their dissolution into the fermentation material system.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
