Abstract: A commodity dryer for removing or providing moisture and controlling atmosphere which surrounds stored commodities such as grain is provided which reduces the growth of bacteria, fungus and minimizes other deleterious conditions encountered such as in the storage of moist commodities which generally render them unfit for subsequent consumption. The commodity dryer maintains the integrity of stored commodities by creating a controlled atmosphere conducive to the removal or the addition of water by capillary action from the pores of the commodity and for controlling the moisture and temperature around the skin of the grain to achieve optimum storage conditions for the specific commodity stored.
