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 the gaseous drying medium through the second heat exchanger after it has been circulated through the dryer. A sheller connected to the dryer receives the dried ear corn from the dryer and shells and the cobs are cycled to the incinerator as fuel therefor.
