When the grains can be dried to the final moisture within the drying time set in advance by the solar drying section 2, the finished dried grains are sent from the solar drying section 2 to the shipping section 5 and subjected to deaeration and other necessary preparation processing. Packed and shipped. Undried cereals are harvested paddy with a moisture of 24
%, And the finished moisture of the paddy is about 14%.

If the grain cannot be dried to the final moisture within the drying time set in advance by the solar drying unit 2, the grain is dried to the maximum in the setting time in the solar drying unit 2, or dried to a predetermined moisture. In addition, it is sent to the storage drying unit 3 and dried by ventilation of room temperature air during storage, and when it can be dried to the final moisture here, the finished dried cereal is sent to the shipping unit 5 and subjected to required preparation processing before shipping. If there is not enough time to dry to the final moisture in the storage / drying unit 3, it is sent to the heating / drying unit 4, heated and dried to the final moisture, sent to the shipping unit 5, and subjected to required preparation processing before shipping.

In the illustrated drying preparation facility, the undried cereals received by the receiving unit 1 are directly sent to the storage drying unit 3 to be dried to the final moisture by storage drying, and the shipping unit 5 is operated.
Or the undried cereals are sent directly to the heating and drying unit 4 where they are dried by heating and dried to finish moisture and then shipped.
