  • Publication number: 20250035312
    Abstract: The present invention relates to a humidity detection-based pellet grill control method and a feeding system of a pellet grill, where the pellet grill is energized so that the feeding system thereof and a humidity sensor on the feeding system are in an energized state; and the humidity sensor is used to continuously monitor humidity of a fuel conveying channel of the feeding system in which a pellet fuel has been stored, so that a controller determines humidity level of a space environment or the pellet fuel in the fuel conveying channel. This can prevent the fuel that has become powdered due to moisture from drying into hard lumps again in the fuel conveying channel which can result in blockage of a screw conveyor, thus protecting the feeding system and reducing maintenance costs.
