Abstract

See full text

A grain handling system having an air system is presented that is capable of automatically detecting and clearing a plug in a tube of an air system using a central controller, an air pressure sensor, a dynamic pressure relief valve and a variable frequency drive connected to and controlling a blower motor. When a plug is detected, the central controller stops the flow of grain into the tube and ramps up the output of the blower motor to full capacity. Thereafter, the central controller performs an unplugging routine by opening and closing the dynamic pressure relief valve causing surges of air to impact the plug either breaking up the plug or bumping the plug along the tube until it clears. Once the plug clears, the central controller resumes normal operation.
