A pellet hopper for use in a pellet grill includes a first bottom panel, a second bottom panel, and a third bottom panel. Each bottom panel has an inner edge that partially defines a pellet evacuation opening. The first, second, and third bottom panels form respective first, second, and third nonzero angles relative to a horizontal plane. In this way, each bottom panel tilts downward toward the pellet evacuation opening.

A cooking grill includes a container defining a combustion area and a cooking surface over the combustion area. The grill features a pellet burner unit disposed within the container under the cooking surface and a pellet feeding device arranged to feed pellets into the burner unit. The burner unit comprises a trough into which the pellets are fed. The trough is mounted in a movable support which can be pulled out from within the container. The feeding device includes a removable cartridge for containing pellets and a receptacle for receiving the cartridge inserted thereon so that the cartridge supplies pellets for transfer to the pellet burner unit. In addition, a gas burner system is arranged in the container adjacent to the pellet burner unit so as to apply heat from the gas burner system to the cooking surface in addition to or as an alternative to the pellet burner unit.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes an ignitor configured to be activated. The ignitor has a duty cycle associated with a number of activations of the ignitor. The example pellet grill further includes one or more processors configured to determine whether the duty cycle has violated a threshold. The one or more processors are further configured, in response to determining that the duty cycle has violated the threshold, to generate a notification indicating that the threshold has been violated. The one or more processors are further configured to cause the notification to be presented at a user interface of the pellet grill.

An automated self-contained pellet grill includes a base housing that defines a heat distribution chamber with a cooking grid supported in an opening at the top of the base for supporting food to be cooked. A pellet burning mechanism, located within the housing, includes a pellet feeder driven by an electrical motor. Electrical power is provided for the motor by a thermoelectric generator having a hot side that is heated by burning pellets and a cold side that is cooled by flowing ambient air.

The present disclosure provides a quickly-repairable pellet grill. The pellet grill includes a pellet grill body, wherein the pellet grill body comprises a fuel conveying and stirring mechanism, a fuel feed cabinet, a combustion furnace, and a fuel conveying channel communicated with both the fuel feed cabinet and the combustion furnace; wherein the fuel conveying and stirring mechanism includes a stirrer disposed on the fuel conveying channel, a rotation driving device, and a connection base, the connection base being detachably mounted at a mounting port of the fuel conveying channel, the rotation driving device being mounted on the connection base, the stirrer being mounted at a rotation portion of the rotation driving device, a handle being disposed on the connection base.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

A biomass burner includes a hopper, a ventilating chamber, a U-shaped fire box, a feeding cylinder including an output end, an auger, a feeding motor including a driving wheel, an ignition device, an ignition motor, a ventilation plate, a first poking device, a second poking device, a first poking motor configured to drive the first poking device, a second poking motor configured to drive the second poking device, a first fixed plate, and a second fixed plate. The hopper is disposed below the feeding cylinder. The feeding cylinder is disposed through the ventilating chamber and the output end of the feeding cylinder extends into the U-shaped fire box. The auger is disposed in the feeding cylinder and is driven by the feeding motor; one end of the auger is provided with a driven gear, and the driven gear is meshed with the driving wheel of the feeding motor.
