Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation production equipment and relates to a tryptophan fermentation device. Background Art

[0002] L-Tryptophan is one of the eight essential amino acids in human and animal life activities. It plays an important role in the growth, development and metabolism of humans and animals. It cannot be synthesized by itself and can only be taken in through food. L-Tryptophan can be widely used in medicine and nutrition, food applications, feed additives, agriculture and environmental monitoring.

[0003] In recent years, with the development of L-tryptophan in medicine, food and feed, the market demand has continued to increase. L-tryptophan has become a product with good development prospects in the international market and large demand in the domestic market. The current production volume is far from meeting the market demand. Therefore, improving the fermentation yield of L-tryptophan, reducing production costs, and realizing industrialized production have become an important research direction. Utility Model Content

[0004] The utility model aims to provide a tryptophan fermentation device.

[0005] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: a tryptophan fermentation device, comprising a fermentation tank, a high-pressure liquid sugar tank, a feeding tank and a sterile air device; a first baffle and a second baffle are provided in the fermentation tank, and the first baffle and the second baffle are both hollow structures, and the first baffle and the second baffle are both provided with small holes facing the fermentation tank; the high-pressure liquid sugar tank and the feeding tank are connected to the first baffle through a pipeline, and the sterile air device is connected to the second baffle through a pipeline.

[0006] The preferred technical solution is that the diameter of the small hole is 1-3 mm.

[0007] The preferred technical solution is: a stirring shaft is provided in the fermenter, and at least two groups of stirring paddles are provided on the stirring shaft; and the height of the first baffle is equal to the distance between the two stirring paddles.

[0008] A preferred technical solution is: it also includes a steam generating device, and the steam generating device is connected to the first baffle and the second baffle through pipelines respectively.

[0009] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0010] The utility model is used in the process of tryptophan fermentation production. The baffle itself has the function of changing the flow direction of the liquid, causing the liquid to tumble violently, and enhancing the dissolved oxygen mass transfer. The baffle in the fermentation tank is designed to be hollow and has holes on it. The first baffle is connected to the air pipeline, so that the air is distributed more evenly when entering, and the dissolved oxygen is increased. The second baffle is connected to the liquid sugar and the feed, so that the sugar and the feed enter the fermentation tank and are broken up by the stirring paddle, and the distribution is more even, reducing the byproducts generated by the excessive local sugar concentration, which is beneficial to the acid production and conversion rate of tryptophan.

[0015] See also Figure 1-2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no technical substantive significance, and any structural modification, change in proportional relationship or adjustment of size. The following examples are provided for a better understanding of the utility model, but not to limit the utility model. The experimental methods in the following examples are all conventional methods unless otherwise specified. The experimental materials used in the following examples are all purchased from conventional biochemical reagent stores unless otherwise specified.

[0016] Example 1: A tryptophan fermentation device

[0017] like Figure 1As shown, a tryptophan fermentation device comprises a tank body 1, and a first baffle plate 2, a second baffle plate 3, several groups of stirring paddles 9-11, a high-pressure liquid sugar tank 5, a feeding tank 6, and a sterile air device 4 located inside the tank body. The sterile air device 4 is connected to the first baffle plate 2 inside the tank body through a pipeline 6, and the high-pressure liquid sugar tank 5 and the feeding tank 7 are connected to the second baffle plate 3 inside the tank body through a pipeline 8; the first baffle plate and the second baffle plate 3 are hollow inside and the bottoms are connected to the pipeline 6 and the pipeline 7 respectively; small holes 12 are evenly distributed on the first baffle plate 2 and the second baffle plate 3, and the aperture of the small holes 12 is 1-3 mm; the length of the first baffle plate 2 and the second baffle plate 3 is the length from the first stirring paddle 9 to the third stirring paddle 11; the installation height of the first baffle plate 2 and the second baffle plate 3 is the same as the height of the several groups of stirring paddles 9-11.

[0018] Working principle: The utility model is used in the process of tryptophan fermentation production. The baffle in the fermentation tank is designed to be hollow and has holes on it. The first baffle is connected to the air device through a pipeline. When the air enters the fermentation tank, it is more evenly distributed after stirring, thereby increasing the dissolved oxygen. The second baffle is connected to the liquid sugar tank and the feed tank through a pipeline. When sugar and feed need to be supplemented, the sugar and feed are forced into the fermentation tank by pressure. In this way, when sugar and feed enter the fermentation tank from several small holes on the baffle, there are more feeding points compared to entering from a single tube on the top, and the stirring and dispersion are more evenly dispersed by the stirring paddle next to it, which can reduce the by-products produced by excessive local sugar concentration, and is beneficial to the acid production and conversion rate of tryptophan. A separate steam is passed through the pipeline connecting the baffles on both sides to ensure the sterility of the pipeline and the inside of the baffle.

[0019] The above description is only used to explain the preferred embodiment of the utility model, and is not intended to limit the utility model in any form. Therefore, any modifications or changes made to the utility model under the same spirit of the utility model should still be included in the scope of protection intended by the utility model.
