ABSTRACT:
A water adding control apparatus includes a microwave detecting unit which enables the detection of microwave value proportional to the water content amount of the water added grain and which makes it unnecessary to make calculations for an estimated water content value of the water added grains. The water adding process is started by inputting initial water adding amount, the microwave value of the raw grain after the addition of water is measured, the measured microwave value is set as the target microwave value which serves as control reference, and the water adding amount is feed-back controlled for the actually measured microwave value to constantly match the target microwave value.
