8. Electric operation control system: the system adopts centralized operation, and full-automatic programming control system or semi-automatic control system can be available according to customer requirements.
Continuous countercurrent extraction equipment can adopt intelligent control system to realize automation control and online analysis of technological parameters in the extraction process, control optimization, intelligent control and intelligent manufacturing management, which can decrease jamming, steadily control the quality and uniformity of the extracted products, increase efficacy and yielding and reduce consumption of raw material and energy, thus realizing efficiency, stability, controllability, energy conservation and safety.
There are various structures of control system for choosing: IPC, PLC, PLC+IPC, intelligent controller + IPC, etc.
Main function include:
1. To detect and control the technological parameters in the extracting process, mainly including solvent flow, material flow, extracting time, extracting temperature, liquid level and pressure, and automatically control the extracting process in accordance with set formula;
2. To build a mathematical model based on process mechanism and test data, to analyze important technological parameters dynamically, and to conduct optimization and intelligent control for operating conditions according to current technical parameters
3. Monitor operational process through interfaces of process flow, tendency, warning and control
Conduct data management for formula, real time, history, warning and system parameter through the database system.
