Abstract

A control unit sensitive to the condition of its ambient atmosphere is enclosed within an insulated housing over lateral openings in the discharge auger tube of a grain drying bin whereby gases surrounding the discharged grain circulated into contact with said unit. The unit is connected to control the operation of the discharge auger, thereby controlling the moisture content of grain being discharged. In one embodiment, a warm-air circulation jacket is disposed about the control unit housing to establish a constant housing temperature and obviate any temperature effects of the exterior atmosphere.
