摘要
研究了生物制药或食品生产中连消灭菌工艺及自动控制系统的设计.针对连消灭菌工艺的目标和要求,考虑到热传导、流体力学和传质等因素,设计了多种发酵原料的连消灭菌工艺,开发了基于P LC和PID控制的自动控制系统.系统能够根据工艺要求自动控制灭菌过程中的温度、压力和流量等关键参数,实现一键启停操作,简化了操作流程,提高了灭菌工艺的稳定性和可靠性.通过实际运行,验证了连消灭菌工艺及自动控制系统的可行性和有效性.
Abstract
The design methods of continuous sterilization processes and automatic control systems in the field of biopharmaceutical or food production are mainly studied in this paper.In view of the goals and requirements of the continuous sterilization process,considering factors such as heat conduction,fluid mechanics and mass transfer,the continuous sterilization process of a variety of fermentation raw materials is designed,and an automatic control system based on PLC and PID control is developed.According to the process requirements,the key parameters such as temperature,pressure and flow rate in the sterilization process can be freely controlled by the system to realize one-button start-stop operation,which simplifies the operation process and improves the stability and reliability of the sterilization process.Through actual operation,the feasibility and effectiveness of the continuous sterilization process and automatic control system are verified.
