Control characteristics and parameters:

1The system adopts a large capacityPLCProgram controller, LCD touch screen display, and digital input settings.

2Control principle: The analog signal of the fermentation process control parameters is detected by a transmitter and converted into a digital signal, which is transmitted toPLCExecution control, touch screen display and settings form a complete set of fermentation equipmentDCSDistributed lower computer automatic control system.

3Control parameters: fermentation temperature, stirring speedPHValueDOValue, defoaming, multi-channel feeding, pressure, ventilation volume (manual), etc.

4Touchscreen animation displays the status of fermentation process control parameters; Digital setting and rapid calibration of various control parameters; Automatically record temperature curvesPHValue curve; Storage, playback, and printing of fermentation process parameters; Password management; Parameter over limit alarm; The lower computer is reservedRS232Upper computer communication interface andCOMInterface,COMThe interface can transfer various data of the fermentation process to the office computer for parameter analysis, comparison, and long-term storage of each batch.

5Due to the high temperature and humidity environment suitable for fermentation equipment, in order to ensure the long-term stability of the system, our company uses imported brands and well-known domestic brands for key components and parts.

6Our company selects touch screens of different models, specifications, and sizes based on the number of fermentation tanks controlled by customers. Customers can intuitively monitor the entire fermentation process of each fermentation tank, which is easy to use and operate quickly.

7The control system software is independently developed by Kehai Shenggong and applied for patent protection to the China National Intellectual Property Administration.
