Abstract

PURPOSE:To select switching of a cereal drier from hot blast drying to rest drying according to the barrel crack of the grade state of cereals and a rate of mixture of unriped grain. CONSTITUTION:When the moisture content of cereals under drying attains a given value, switching to rest drying from hot blast drying is selected through detection of the grade state of cereals and according to the detected barrel crack and a rate of mixture of unriped grain. Since drying is controlled by the grade state of the cereals under drying, drying efficiency is improved and dried cereals of good quality are obtained.

The operation of the above embodiment will be described below. The start switch 3 for operating the setting scoops 40, 41, 42 of the operating device 14 to predetermined positions to start the grain drying operation.
By operating 8, each part of the grain dryer 5, the burner 4, the moisture sensor 3, etc. are started, and the hot air set by the burner 4 is generated. This hot air is blown from the blower chamber 10 to the grain drying chamber 2, After passing through 2, the exhaust chambers 9, 9 and the exhaust passage chamber 15 are sucked and exhausted by the exhaust fan 17, so that the grain storage chamber 1
The grains contained in the drying chamber 2,
While being flowed down in 2, it is exposed to the hot air and dried, and is fed to the lower part by the feeding valves 11 and 11 to flow down to the grain collecting trough 12.
From the feed trough 28 into the grain raising machine 25 by a lower transfer helix, and is conveyed to the upper portion by the bucket conveyor 26, is fed into the transfer trough 7 through the outlet cylinder 27, and is diffused from the transfer trough 7. Transferred by the upper transfer spiral onto the board 24,
When the moisture sensor 3 detects the same grain moisture as the finishing target moisture set by operating the moisture setting scoop 40, the moisture is uniformly diffused and reduced into the storage chamber 1 by the diffusion board 24 and circulated and dried. When it is detected that the grain has been dried, the control device 45
Automatically controls the dryer 5 to automatically stop the drying of the grain.

During the drying operation, when the grain moisture detected by the moisture sensor 3 has a predetermined moisture content higher than the finishing target moisture set by operating the moisture setting picker 40, the grain being dried is dried. Grains are hulled by a hulling device 33 of a grain inspection device 31, and this brown rice that has been hulled and sorted is a brown rice quality meter 37.
The quality of brown rice is detected at, and from the detection of barrel cracks and immature grains in the quality, the cracking mixture ratio and immature grain mixing ratio are detected, and hot air drying is switched to pause drying according to these detected values. After the pause drying is performed for a predetermined time, it is switched to hot air drying again to dry the grain, or the dry drying is not switched to the pause drying, but the grain drying speed is changed to the predetermined low speed to dry the grain. Or the grain is dried at the same hot air temperature without switching to rest drying, or any of the above is selected to dry the grain.
