To provide a grain drying machine capable of reflecting intention of an operator also in the handling for moisture mottle convergence in addition to grain drying with a desirable drying speed.
A grain drying machine is configured such that drying operation of patched grain is permitted with a drying speed (V0) preset from among drying speed candidates, and includes stratified moisture value measurement means (20) of the patched grain, calculation means of calculating a circulation time (H) required for convergence of the measured stratified moisture value, display means (13a) of drying conditions and a moisture mottle convergence mode which can be selected for the handling of a moisture mottle. Therein, according to the moisture mottle convergence mode, the resetting of the drying speed (V1) and the display of the drying speed are permitted in such a range that the drying time gets to the circulation time (H) or more.
