Abstract
A control system for a grain drying bin includes a pre-dry sensor mounted on the inside of a grain drying bin a short distance above the floor and a thermocouple grain temperature sensor mounted in the discharge tube of the grain drying bin. The discharge grain temperature sensor includes a thermal contact member made of copper or other heat conductive material having a thermocouple bonded thereto to intimate heat conducting relationship. The thermal contact member is mounted by a mounting block to the discharge tube to extend through a slot into the interior of the tube and is shaped to allow the grain to flow around it in thermal contact therewith. A gap is provided in the fighting of the discharge auger in order to provide clearance for the thermal contact member. The control system prevents discharge of grain until the pre-dry temperature is attained, and controls stopping of the grain discharge, in either a sample mode or a discharge mode, if the discharged grain is too cool.
