What are the factors that affect the fermentation of fermentation equipment?Parameters of environmental and chemical state changes, including cell growth rate, product synthesis rate and respiratory rate, etc. It can only be obtained by means of computer calculations and specific mathematical models. The other category is parameters that are difficult to detect with sensors so far, such as temperature, pressure, stirring power, rotational speed, foam, fermentation broth viscosity, turbidity, pH, ion concentration, dissolved oxygen, matrix concentration, etc. referred to as an indirect parameter. These parameters need to be based on some directly detected parameters, which are called direct parameters. Among the above parameters, temperature, pH, dissolved oxygen concentration and other factors that affect the fermentation of fermentation equipment have a greater impact on the fermentation process. How to control the theory, the entire fermentation process You should not choose only one incubation temperature. In the growth stage, a suitable growth temperature should be selected, and in the product secretion stage, a suitable production temperature should be selected. However, in actual production, due to the large volume of the fermentation broth, it is difficult to raise and lower the temperature, so in the whole fermentation process, a more suitable culture temperature is often used to make the yield of the product very high, or to carry out fermentation under possible conditions. Appropriate adjustments. The fermentation temperature can be detected by a thermometer or an automatic recording instrument, and adjusted by passing cold water, hot water or steam into the jacket or coiled pipe of the fermenter. Because a large amount of fermentation heat is released during fermentation, it is usually necessary to cool it down in this case, and use an automatic control or manual adjustment valve to pass the cooled water into a jacket or a coiled tube to cool down through heat exchange , keep constant temperature fermentation.

The main structure of fermentation equipment includes cylinder body, upper and lower heads, heat exchange device, stirring, monitoring and measuring equipment, etc.
