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, a plurality of drying containers are mounted on a conveyor and circulated in a drying chamber. Therefore, a space other than the storage of sample grains, for example, an installation space of 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,
Despite the fact that the moisture content of the sample grains at the time of introduction is not uniform due to differences in harvest locations, etc., the drying time is substantially constant, so the sample grains are easily taken out in an over-dried or undried state, There is a problem that the quality of the sample grain is easily lowered.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a drying apparatus for independent inspection in which a plurality of drying containers for storing sample grains are installed in a drying chamber. Are provided side by side in the vertical and horizontal directions, and a moisture sensor is provided in a holder that is moved in a vertical direction and a horizontal direction by a moving member.
The drying chamber is installed vertically so that the space inside the drying chamber containing sample grains can be expanded more easily than before by effectively using the drying chamber and increasing the volume of the drying chamber. It is possible to increase the number of drying vessels more easily than before without increasing the size, and even if a sample grain with non-uniform moisture content is put into each drying vessel, the moisture sensor moves up and down in each drying vessel. Since the moisture detection of the grains is performed, the drying time can be easily set for each drying vessel, and the sample grains in each drying vessel can be automatically dried to a predetermined moisture content for performing a fair quality inspection. is there.
