Nutrition-enriched gain manufacturing apparatus and gain drying facility including the same

A nutrition-enriched grain manufacturing apparatus comprising:

• heating means for heating grain;
• an accumulation portion which has a heat retention function of accumulating the grain heated by the heating means in a state of being heat-retained;
• drying means for drying the grain which has been accumulated in the accumulation portion;
• and
• main control means for controlling the heating means such that a grain temperature is a predetermined temperature set to be equal to or higher than 52° C. and equal to or lower than 80° C. based on measurement by a grain temperature sensor which measures the grain temperature of the grain to perform a nutrition enriching processing of enriching a content of gamma aminobutyric acid in the grain, controlling a time during which the heated grain is accumulated in the accumulation portion based on measurement by means for measuring a time to control such that the nutrition enriching processing of enriching the content of the gamma aminobutyric acid in the grain is performed with residual heat for a predetermined time, and controlling the drying means to dry the grain which has been subjected to the nutrition enriching processing,
• wherein the accumulation portion is provided at a downstream side in a transfer direction of the grain with respect to the heating means and the drying means is provided at a downstream side in the transfer direction with respect to the accumulation portion, and a non-circulated system in which the grain is not transferred from the drying means to the heating means is employed, and
• the heating means is means for heating the grain in a space in which a blower and an air exhaust device are not provided or means for heating the grain in a space to which humid hot air is supplied from a humid hot air supply port.
