Conventional technology In the past, grains stored in a storage chamber were fed out from the storage chamber into a drying chamber and flowed down, while hot air generated by a burner and a certain amount of drying air passing around the burner were removed using an exhaust fan. By sucking air into the drying chamber, the air is sucked and exhausted by the exhaust fan, and while the grains flowing down the drying chamber are exposed to this hot air and this drying air and dried, a moisture detection sensor is used to dry the grains. Detects the moisture value of the grain during this drying cycle,
The drying speed of the dried grains is detected based on this detected value, and this detected grain drying speed is compared with a set grain drying speed that is set and stored in the control device, and the detected grain drying speed is determined by the set grain drying speed. This was a grain drying control method in which the temperature of the hot air generated from the burner was changed and controlled by the control device so that the temperature was the same as the grain drying speed.

Problems to be Solved by the Invention The grains housed in the storage chamber can be removed from the drying chamber by sucking hot air descending from the storage chamber and a certain amount of drying air passing around the burner. The grains flowing through the drying chamber are exposed to the hot air and the drying air and dried, and a moisture detection sensor detects the moisture content of the grains during the drying circulation. Detect the value and
The drying speed of this grain is detected based on this detected value, and this detected grain drying speed is compared with a set grain drying speed that is set and stored in the control device, and the detected grain is In a grain drying control type dryer, the temperature of the hot air generated from the burner is changed to a high temperature or a low temperature by the control device so that the drying speed is the same as the detected grain drying speed. As the drying of the grains progresses, the density of the grains in the drying chamber becomes denser, so that the amount of drying air passing through the drying chamber decreases, and therefore the thermal efficiency in the drying chamber section decreases,
In order to prevent this decrease in thermal efficiency, the temperature of the hot air generated by the burner must be controlled to be higher than necessary, which may increase fuel consumption.
