Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain drying time setting device for a grain dryer. A manual moisture detection sensor detects the moisture value of the grains and stores them in the storage chamber, calculates the drying time of the grains based on the detected moisture value, and uses a time setting device to set the drying time to this calculated time. is operated and set to start drying the grains, and while the grains stored in the storage chamber are allowed to flow down from the storage chamber into the drying chamber, the hot air generated from the burner is passed through the drying chamber and an exhaust fan is operated. It was a device that sucked and exhausted the air and exposed it to this hot air to dry it.

Problems to be Solved by the Invention - After detecting the moisture value of the grains to be dried using a manual moisture detection sensor, the grains are stored in a storage chamber,
The drying time of the grain is calculated based on the detected moisture value detected by the moisture detection sensor, and the calculated drying time is set by operating a time setting device to start drying the grain. While the grains stored in the storage chamber are flowing down from the storage chamber into the drying chamber, hot air generated from a burner is passed through the drying chamber and sucked and exhausted by an exhaust fan, thereby reducing the amount of grain that is flowing down inside the drying chamber. In dryers that dry grains by exposing them to this hot air, the drying time is calculated by calculating the moisture value detected by the moisture detection sensor. If you operate it incorrectly, the grains to be dried may become undried or over-dried, and if over-dried, the grains may turn to the side or break up. .
