Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a biological reaction kettle. Background Art

[0002] A reaction kettle is a metal container. Generally speaking, a reaction kettle is a stainless-steel container with physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Along with this, the design requirements for the container are also different according to the pressure requirements during the reaction process.

[0003] During the fermentation and catalytic reaction process of fungal organisms, a large amount of gas and heat will be generated in the reaction kettle, resulting in an increase in the air pressure inside the reaction kettle. Therefore, the raw materials inside the biological reaction kettle may be in a high-temperature and high-pressure environment during the reaction process. And during the biological reaction process, sampling and detection are required to understand the state of biological fermentation. However, during the sampling process under high-pressure conditions, it is easy for the objects inside the reaction kettle to spray out, making it difficult to sample them. For this reason, we propose a biological reaction kettle. Content of the Utility Model
