In addition, a plurality of partition plates of decreasing length in the vertical direction were installed inside each preliminary mixing tank to divide the inside of each preliminary mixing tank into multiple blocks, and an inlet was provided on the tallest block. Therefore, by putting grains of different varieties to be mixed into each preliminary mixing tank through the inlet, the grains of the same brand can be sequentially separated into each layer in each block in the preliminary mixing tank. Moreover, by discharging the grains of each brand stored in each preliminary mixing tank at the same time, each layer of grain of each brand with different properties is discharged from each preliminary mixing tank, making it possible to distinguish between the beginning and end of the rice mixing process. This reduces the difference in properties and makes it possible to obtain a uniform mixed rice product.

Furthermore, each preliminary mixing tank was assembled into one tank, and an agitation device was installed at the bottom of this tank via a grain plate, so that each preliminary mixing tank was immediately removed from the tank. A conveying device that allows the mixing of different brands of grains separated into each discharged layer and sends the grains to the stirring device without the risk of the grains being scattered outside by the stirring device. is not particularly necessary either.
