Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of reaction kettle, especially to a dehydration reaction kettle for fermentation engineering. BACKGROUND

[0002] In the field of fermentation engineering, especially in the fermentation production process of fusidic acid, the dehydration treatment of materials plays a crucial role. As an important antibiotic, the fermentation production of fusidic acid has very high requirements for environmental conditions and fine treatment of raw materials.

[0003] Traditional fermentation processes often face many challenges in the dehydration link. On the one hand, anhydrous sodium sulfate raw materials used to assist dehydration are prone to caking due to the absorption of moisture in the air during storage or transportation. These caked anhydrous sodium sulfate not only cannot be evenly dispersed in the fermentation materials, but also have a significantly reduced effective area, resulting in low dehydration efficiency. For example, in some previous small-scale fermentation tests, after directly adding caked anhydrous sodium sulfate, it was found that the moisture removal effect in the local area of the material was obvious, while the other areas were still in a high humidity state, which seriously affected the consistency of the fermentation environment, and thus had an adverse effect on the yield and quality of fusidic acid.

[0004] On the other hand, most existing reaction kettles do not have a device specifically designed for the pretreatment of anhydrous sodium sulfate. They only rely on simple manual knocking or rough mechanical crushing methods, which cannot accurately control the particle size of anhydrous sodium sulfate and cannot meet the fine operation requirements of fusidic acid fermentation production. At the same time, this extensive treatment method easily introduces impurities, which brings pollution risk to the subsequent fermentation process and reduces the purity of the product.

[0005] With the continuous development of fermentation engineering technology, there is an increasing demand for improving the efficiency of fusidic acid fermentation production and ensuring the stability of product quality. In order to overcome the above problems, an innovative solution is needed, i.e. designing a special anhydrous sodium sulfate pre-milling device in the dehydration reaction kettle for fermentation engineering. Through this device, caked anhydrous sodium sulfate is broken and evenly sprinkled in the reaction kettle. Then, with the help of efficient stirring devices, the material and anhydrous sodium sulfate are fully mixed, thus creating a more ideal dehydration environment for the fermentation production of fusidic acid and improving the overall fermentation process level. SUMMARY

[0015] This invention provides a dehydration reactor for fermentation engineering. The grinding component in the pre-grinding device, driven by a grinding motor, rotates a shaft and crushes rollers to break up agglomerated materials such as anhydrous sodium sulfate, reducing their particle size.
