Automation system for a three-tower dryer Mega, as part of production and processing complex, including its integration into the overall system. Automated equipment: 15 fans and common dust aspiration (rotary-valve feeder and fan), 3 discharge mechanisms with controlled speed of discharge, 9 discrete level sensors and 12 temperature transmitters (3 for drying agent, 9 for seed), 2 valves regulating the flow of steam to heat-exchangers (PID-control of position according to the pressure and temperature of the agent). Features: manual control of separate devices from the computer screen; automatic temperature regulation of the drying agent; emergency protection of individual devices, as well as the drying process as a whole (by overheating of the drying agent and/or seed, empty tower, discharge failure, dust aspiration failure) and alarm system; alarm and event log; separate window with trends for analog values (temperature, discharge rate, valve position); flexible adjustment of drying process interlocks.
