[Problem that the invention attempts to solve]

The purpose of this known mixing device is only to set the mixing ratio of the two types of rice to a predetermined ratio, and to continuously supply and mix the two types of rice. In other words, it is not possible to measure the respective volumes or weights of the two types of rice. Even if two types of rice are mixed at a predetermined ratio using such a mixing device, the mixed rice is usually packaged in fixed quantities and handled in bags. Therefore,
In order to bag the mixed rice mixed by this mixing device in fixed quantities, the weight or volume of this mixed rice must be measured by another measuring device and packed into bags, and the subsequent measurement Separate equipment is required to carry out the bagging process.

In addition, since the purpose of this mixing device is only to continuously mix two types of rice as mentioned above, a ribbon screw housed in an inclined case is used as the mixing means. . This mixing by the ribbon screw is limited to the time when the two types of rice that are dropped separately pass through the case equipped with the ribbon screw.
Highly uniform mixing cannot be expected.

In view of the problems of the conventional rice mixing device as described above, the present invention accurately measures a small amount of fortified rice and white rice and mixes them uniformly, while simultaneously
Immediately after mixing the two, this mixed rice is packed into bags so that a series of different operations can be performed continuously.
