Wood pellets manufacturing unit process was automated.
The process involves, Furness, wet wood cutter, Drier rotor, Pelleting machine, packing machine etc.
The machinery process was automated using embedded PLC, motor drives, feed backs. Feed backs includes, limit switches, flow sensors, level sensors, temperature sensors.
A complete closed loop system with PC based HMI software for user interface was implemented.
When the Drier temperature was reached the set value, the chopped wet wood will be loaded into the drier automatically by a conveyer. Another conveyer will control the fuel to the Furness to control the temperature.
The dry wood will go through a hammer and the hammered wood dust will go to Pelleting machine.
Then the dry wood Pellets will be packed in 25 / 50 / 100 Kg bags. The complete process can be monitored and controlled from HMI.
