2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open No. 58-145493, a sample paddy of a lot is put into a plurality of drying containers installed in a drying chamber, and after a certain time, the sample paddy of the lot is removed from the drying container. There is a technology to take out.

[0003]

In the prior art, since a plurality of drying containers are mounted on a conveyor and circulated in a drying chamber, a space other than the storage of sample grains, for example, a space for installing a conveyor or an empty container moving space. Is formed in the drying chamber, the number of drying vessels installed is likely to be limited, and it is necessary to expand the drying chamber to add more drying vessels,
Moisture content of sample grains at the time of input is different at harvest location
Dry time is almost constant despite unevenness due to
The grain is over-dried or undried
Is easy to remove in the
There is a condition .

[0004]
