Description

Technical Field

[0001] The invention relates to the technical field of fermentation, and in particular to a calcium propionate raw material fermentation device. Background Art

[0002] Fermentation refers to the process of preparing microbial cells, direct metabolites or secondary metabolites by using the life activities of microorganisms under aerobic or anaerobic conditions. Fermentation is sometimes also written as fermentation. Its definition varies depending on the occasion of use. Fermentation usually refers to a certain decomposition process of organic matter by organisms. Fermentation is a biochemical reaction that humans have been exposed to for a long time. It is now widely used in the food industry, biological and chemical industries. It is also a basic process of bioengineering, namely fermentation engineering. Research on its mechanism and process control is still ongoing.

[0003] In the prior art, calcium propionate raw materials often need to be fermented during the production process, and most of the existing calcium propionate raw material fermentation methods will produce fermentation broth, and then propionic acid needs to be separated from the fermentation broth, and the propionic acid fermentation broth needs to be separated and decolorized to improve the purity and color of the product. However, since the fermentation broth may contain a variety of impurities, such as residual nutrients, bacterial metabolites, etc., the product needs to be extracted after fermentation. The traditional product extraction method is to extract by filtration or centrifugal separation. In this process, since the product is inside the container and is pressed against the inner wall of the container by centrifugal force, during the product extraction process, fine impurities in the fermentation broth may accumulate inside the product, and cannot be peeled off and removed, which may result in low product purity and affect its subsequent use effect.

Since the powder particle size of the calcium propionate raw material is larger than the filtration pore size of the biological filtration membrane, the fermentation liquid inside the second filter bucket will continuously filter out the microorganisms and fine impurities in the calcium propionate raw material from the holes in the biological filtration membrane, and make them fall into the first mounting frame for collection. In this process, since the calcium propionate raw material is constantly in a state of pushing and displacement during centrifugal separation, the effect of preventing the calcium propionate raw material from accumulating and causing the microorganisms and fine impurities inside to be unable to be separated and filtered can be avoided.

A circular through hole is opened on the bottom surface of the first mounting frame 20, and a sealing plug 61 is movably connected with the inner circumferential wall surface of the circular through hole, so as to discharge the waste water inside the first mounting frame 20.

[0048] Working principle: Please refer to Figure 1-Figure 9As shown, when in use, the staff removes the first mounting frame 20 from the interior of the separation tank 4, and places the biological filtration membrane in the interior of the second filter bucket 44, and then the staff puts the calcium propionate raw material into the interior of the mixing tank 2 through the feeding pipe 10, and then the staff uses the first motor 9. At this time, the rotation of the driving shaft of the first motor 9 will drive the rotating shaft 12 inside the mixing tank 2 to rotate, and then through the engagement relationship between the first connecting block 65 and the second connecting block 66, the two rotating shafts 12 will rotate at the same time, and then the rotating rotating shaft 12 will drive the multiple stirring plates 32 on its surface to rotate, and stir and mix the calcium propionate raw material inside the fermentation tank 1. When the mixture After the raw materials in the tank 2 are mixed, the staff uses the discharge valve 8, and the mixed calcium propionate raw materials in the mixing tank 2 will enter the interior of the fermentation tank 1 through the two connecting pipes 7, and then the staff stops the rotation of the driving shaft of the first motor 9 to allow the calcium propionate raw materials in the fermentation tank 1 to ferment statically. When the fermentation of the calcium propionate raw materials in the fermentation tank 1 is completed, the staff uses the electric valve 5 and the second motor 21, and the calcium propionate raw materials and fermentation liquid in the fermentation tank 1 will enter the interior of the first mounting frame 20 together through the electric valve 5. In this process, the calcium propionate raw materials will fall through the first filter bucket 51 to the surface of the biological filtration membrane inside the second filter bucket 44, and at the same time, The fermentation liquid will enter the interior of the second filter bucket 44 through the first filter bucket 51, and then the first filter bucket 51 will preliminarily filter the calcium propionate raw material and large particles of impurities in the fermentation liquid, and then the second motor 21 will drive the sleeve 58 and the second slide bar 56 to rotate, at this time the second slide bar 56 will drive the adjustment plate 54 and the second filter bucket 44 on the top thereof to rotate, and then the multiple second adjustment blocks 55 at the bottom of the adjustment plate 54 will continuously contact the first adjustment block 53 and make the second filter bucket 44 move up and down reciprocatingly, and then the second filter bucket 44 will move upward so that the calcium propionate raw material inside it will intermittently contact the scraper bar 47, at this time, under the action of centrifugal force and the scraper bar 47, The calcium propionate raw material inside the second filter bucket 44 will gradually adhere to the surface of the biological filtration membrane, and the scraper bar 47 will intermittently push the calcium propionate raw material. Since the powder particle size of the calcium propionate raw material is larger than the filtration pore size of the biological filtration membrane, the fermentation liquid inside the second filter bucket 44 will continuously filter out the microorganisms and fine impurities in the calcium propionate raw material from the holes in the biological filtration membrane, and make them fall into the first mounting frame 20 for collection. In this process, since the calcium propionate raw material is constantly in a state of pushing and displacement during centrifugal separation, the effect of preventing the calcium propionate raw material from accumulating and causing the microorganisms and fine impurities inside to be unable to be separated and filtered can be avoided.
