Control system for the process line and root vegetable drying plant.

One of the two systems for complex control of drying plant chamber, heating system with a complete steam system, heat recovery, portion dozing units, weighing system – weighing facility, bucket conveyor and other auxiliary sub-systems of the drying line. Control systems were engineered based on SIEMENS S7-1500 PLC controller and distributed I/O modules ET200. The system quipped with two HMI panels for controlling various locations in the production facility area. The system equipped with an independent safety controller. The control system controls drying process and so the operation of heating devices is based on PID regulators. Power supply to fans’ drives was made based on conductor lines. Communication with PLC controller via PROFINet.
