2. Description of the Related Art Grains in a grain storage room are supplied to a grain drying room and are fed out while being dried by a feed valve. The fed grains are fried by a grain raising machine and are fed to the storage room. The grains are dried while being repeatedly supplied and circulated.

[0003]

At the start of drying the grain, the falling of the grain is poor due to a coating film or the like attached to each part of the body of the grain drying machine where the grain flows down. If the amount of circulation is reduced and it takes a long time to dry, or if abrasion occurs on a bucket conveyor or the like that transports the grains inside the grain raising machine, the lower part of the grain raising machine In some cases, clogging of the circulating grains may occur, and the present invention is intended to solve these problems.

A configuration of a grain circulation control device for a grain dryer, comprising a control device 35 for changing and controlling the amount of circulated grain fed and circulated by the delivery valve 11 based on the operation time accumulated by the device 31. And

[0005]

The grains in the grain storage chamber 7 are stored in the grain drying chamber 8.
While being supplied and dried, it is fed by the feed valve 11, and the fed kernel is fried by the grain raising machine 25 and supplied to the storage chamber 7, and the kernel is repeatedly circulated. Dries. During this drying, the operating time of the machine 4 of the grain dryer is integrated by the integrating device 31. Based on the accumulated operation time, for example, at the beginning of the drying start, the delivery valve 1
1 is controlled so that the amount of grains to be fed increases and the amount of circulated grains increases, and when the operating time is long, the amount of grains to be fed by the feed valve 11 decreases and the amount of circulation increases. Is controlled so as to be reduced, and the kernel is dried while the circulation is repeatedly performed while being controlled in this manner.

[0006]
