Abstract: A process for optimum usage of energy in the CURING of grain in a bin using free energy of atmospheric air. Optimum utilization of energy in the operation of ventilation fans and dehumidification of atmospheric air without waste of energy is achieved by operating fans and infrared emitters only when required as dictated by the measured temperature differential between the air entering and the air exhausting from the bin. As physiological activity and metabolic processes of the freshly harvested seeds decrease, as indicated by exchanges of heat and moisture between the seeds and the environment, the energy needed to maintain a biologically safe environment also decreases.

Abstract: The invention concerns a new type of metal clad door. The metal clad door according to the invention is built from a unique internal metal frame with two external panels of galvanized sheet metal on either side of the frame.
