fermentation container intelligent expert system

Technical description:

The intelligent expert system of grass fermentation container is the field monitoring, control and decision-making analysis center of liquid strain fermentation container. The system includes: sensing system, acquisition system, control system, intelligent control terminal, expert analysis and decision system five main parts. The system communicates with the environmental data collection system of grass yeast container through the Internet of Things to receive the environmental data uploaded by the collection system. The environmental parameters that can be collected and analyzed by the data collection system include: real-time collection of physical and chemical parameters in the biological fermentation process, including: temperature, pressure and flow rate of microbial fermentation air source water system; Fermentation vessel in microbial fermentation process: temperature, pressure, stirring speed, air and feed liquid flow rate, flow rate, level, pH, DO, EC, ORP, dissolved carbon dioxide; The metabolites in the fermentation process: monitoring the partial pressure of O2 and the partial pressure of CO2, calculating the ratio of the volume of carbon dioxide released and the number of moles of oxygen absorbed by the organism at the same time, that is, the molecular ratio of CO2 released by respiration and O2 absorbed by respiration (RQ); The control system can control the pressure and flow of the air source water system, the flow and pressure of metabolites, the temperature and pressure of the container and the flow rate of the fermentation medium during the fermentation process. By systematically subdividing each fermentation process, the expert decision-making system completes the computer control and control of different stages of humid heat sterilization stage, medium preparation stage, fermentation production stage, and fermentation metabolism product extraction stage, respectively. The whole fermentation control stage is divided into: lag phase, or: Stagnation, adjustment, or lag), logarithmic phase, deceleration phase, and stationary phase (or: Stable period), death phase (death phase, or decline period) curve level accurate management and intelligent control; The product is self-developed by Xiaocao, designed according to industrial embedded server standards, has obtained a number of invention patents, software has obtained software copyright certificate.
