Abstract
A computer controlled grain dryer system includes a grain drying chamber, an air heater unit, and an arrangement of grain loading and unloading conveyors. A grain moisture sampling system receives a grain sample from the grain chamber and conveys the sample to a capacitive sample cell. A grain moisture meter measures grain moisture content as a function of the dielectric constant of the sample in the cell. A digital computer is interfaced with the moisture meter and the grain conveyor and is programmed to automatically control the grain sampling and the drying process. In continuous crossflow and concurrent flow dryers, the drying process is controlled by controlling the speed of grain flow. In batch type dryers, the process is controlled by way of the time that the grain is present in the drying chamber.
