Description

Technical Field

[0001] The utility model relates to the field of microbial fermentation, in particular to a microbial fermentation tank capable of preventing backflow. Background Art

[0002] In the field of microbial fermentation, fermenters are one of the core equipment. With the continuous development of biotechnology, the performance requirements of fermenters are becoming increasingly higher. Currently, microbial fermentation processes often face the problem of backflow, which has brought many adverse effects to fermentation production.

[0003] However, existing microbial fermenters lack effective liquid level control during fermentation, making them prone to overfeeding. When the liquid level in the fermenter is too high, failure to promptly stop the flow of liquid can lead to overflow, resulting in resource waste and environmental pollution. Furthermore, in some cases, backflow can also occur. Furthermore, backflow can severely impact the normal fermentation process, hindering subsequent fermentation processes and reducing fermentation efficiency and product quality. Furthermore, relying solely on manual liquid level observation to control the opening and closing of the feed valve is not only inaccurate but also inefficient, making it difficult to meet user needs.

[0004] Therefore, in order to solve the backflow problem in the microbial fermentation tank, there is an urgent need for a microbial fermentation tank that can accurately control the liquid level and effectively prevent backflow. Utility Model Content

[0009] Furthermore, a controller is provided on the outside of the tank body, and the controller is electrically controlled and connected to the first conductive block, the second conductive block, the alarm, and the liquid inlet pump respectively.
