Patent ID: 8479408

Claim:
A system for drying grain to a desired moisture content, comprising: a grain dryer having a grain pathway between an intake and a discharge, the grain dryer comprising: a forced air heating system for forcing heated air across grain in the grain pathway; a grain mover which establishes the rate of grain movement in the grain pathway; a grain turner for moving grain from an air upstream side in the grain pathway to an air downstream side in the grain pathway, and for moving grain from an air downstream side in the grain pathway to an air upstream side in the grain pathway; a midpoint moisture sensor and a midpoint temperature sensor positioned within the grain dryer at a location after the turner in the grain flow and at a position from 40% to 80% of the grain flow travel from the intake to the discharge through the grain dryer; and a controller receiving data from the midpoint moisture sensor and the midpoint temperature sensor, the controller controlling the grain mover speed based upon the received data.
