Background In the field of beer brewing, the plateau areas provide a unique natural environment for brewing beer with special flavor due to unique climatic conditions such as lower air pressure, larger day and night temperature difference and relatively pure water source. However, conventional beer fermentation apparatuses often face many challenges in the highland environment, such as low fermentation efficiency, improper foam control, serious flavor loss, etc., which limit the improvement of quality of the highland-brewed beer and the development of industry. In the traditional beer fermentation process, stirring and mixing are key steps for ensuring the uniform distribution of fermentation liquor and improving the fermentation efficiency. However, the pressure in the plateau area is low, foam generated in the fermentation process is not easy to naturally dissipate, and excessive foam not only affects the effective volume of the fermentation tank, but also can overflow the tank body, so that raw material waste and environmental pollution are caused.
