Abstract: A method for providing higher yielding seed corn comprising a single-pass, reversing, high air velocity process. Another aspect of the invention concerns a conversion panel for converting a dual-pass seed corn drying system into a single-pass system.

Abstract: A seed corn sheller has a fixed disk for receiving corn through a central aperture thereof, spaced away from a rotating disk. The disks are faced with a contoured material which is soft but abrading. Corn cobs are fed between the disks and move to the perimeter thereof while being shelled. Corn and cobs are discharged separately from the apparatus.

Abstract: An apparatus and method for drying seed corn using cobs and unusable seed corn as fuel for heating the drying medium for drying the seed corn. Products of combustion from an incinerator for incinerating cobs is supplied to a heat exchange medium circulating apparatus having a first heat exchanger and a series of second heat exchangers connected in parallel with each other and in series with the first heat exchanger, and a means for circulating a heat exchange medium through the circulating apparatus for heating the heat exchange medium. A plurality of ear corn dryers for drying seed corn in the form of ear corn each have a gaseous drying medium circulating apparatus control system for alternately circulating a gaseous drying medium in opposite directions through the dryers. Each drying medium circulating apparatus is connected to one of the second heat exchangers for recirculating said gaseous drying medium through the second heat exchanger after it has been circulated through the dryer.
