Grain dispenser and method of controlling same

A method of controlling a grain dispenser including a storage device in which different kinds of grain are stored, the method comprising:

• determining kinds of grain to be dispensed, an amount of the kinds of grain to be dispensed, and a multigrain mixture ratio in a case where a request of a user is received;
• measuring a moisture content ratio of at least one kind of grain and determining a moisture content ratio of a multigrain mixture resulting from mixing two or more kinds of grain, from the measured moisture content ratio;
• controlling a storage device storing at least the two or more kinds of grain in such a manner that two or more kinds of grain are dispensed into a stirring and washing container, on the basis of the different kinds of grain to be dispensed, the amount of the different kinds of grain to be dispensed, and the multigrain mixture ratio that are determined;
• stirring the different kinds of grain, which are dispensed into the stirring and washing container, in such a manner as to be mixed with each other to form a multigrain mixture;
• determining a washing time for the multigrain mixture, the number of times of washing of the multigrain mixture, and an amount of water for meal cooking and a macerating time for the washed multigrain mixture, based on the determined moisture content ratio of the multigrain mixture;
• washing the multigrain mixture according to the washing time and the number of times of washing that are determined;
• supplying an amount of water corresponding to the determined amount of water for meal cooking, to the stirring and washing container, and macerating the multigrain mixture in the supplied water;
• and
• outputting alerting information for alerting the user that the multigrain mixture is completely macerated, in a case where the determined macerating time expires.
