In modern biological fermentation industry, the fermentation tank, as the core equipment, its performance is directly related to production efficiency, product quality and the reliability of cleaning and disinfection. With the continuous improvement of the requirements for the stability and hygiene control of the fermentation process in industries such as biopharmaceuticals, food, brewing and environmental protection, surface treatment technology of fermentation tanks has become an important means to enhance the performance of the equipment. Especially polishing and coating technologies not only affect the microbial adhesion and material transfer efficiency inside the tank, but also significantly relate to the cleaning difficulty and sterilization effect of the equipment. This article will focus on the polishing and coating treatment technology of biological fermentation tanks, and explore its key impact on the fermentation effect and cleaning performance.

The fermentation process is an extremely important part of industrial biotechnology and is widely used in the fields of pharmaceuticals, food, beverages, biofuels, etc. During the fermentation process, the metabolic activities of microorganisms generate a large amount of heat energy. If this heat cannot be dissipated in a timely and effective manner, it will cause the temperature inside the fermentation tank to rise, thereby affecting the growth state and metabolic efficiency of microorganisms, and even leading to fermentation failure. Therefore, how to effectively dissipate the heat generated during the fermentation process and control the fermentation temperature within the ideal range is a key technical issue to ensure the smooth progress of the fermentation process. This article will systematically analyze the sources of fermentation heat, heat dissipation methods and related design techniques, and explore how to achieve effective control of fermentation temperature through reasonable process and equipment design to ensure efficient and stable fermentation production.

Biological fermentation is an important process that applies microorganisms to industrial production and is widely used in multiple fields such as medicine, food, chemical engineering, and energy. During the fermentation process, gas supply (especially oxygen or other essential gases such as hydrogen and carbon dioxide) is crucial for the normal metabolism of microorganisms, cell proliferation, and the synthesis of target products. If the gas supply is insufficient, it may lead to a decline in yield at best, and at worst, it may cause the death of the bacteria and the failure of fermentation. Therefore, solving the problem of insufficient gas supply during the fermentation process is one of the core technologies to ensure the stability of the process and the high yield of products.

With the rapid development of biotechnology, the fermentation process has been widely applied in fields such as pharmaceuticals, food, agriculture, and chemical engineering, bringing about remarkable economic and social benefits. However, the large amount of waste liquid produced during the fermentation process - that is, the fermentation waste liquid - may cause serious pollution to the environment if it is not treated scientifically and effectively. Therefore, how to safely, economically and efficiently handle fermentation waste liquid has become an important issue faced by many biological enterprises.
