Abstract

An improved auger system for delivering combustible material to a burn box within a cooker, such as a grill or smoker, uses a pivotable coupling between the auger shaft and the drive motor, enabling the auger to adjust its alignment within the tube to accommodate irregularly shaped materials, thus minimizing jamming and improving the consistency of material delivery. The system also incorporates a mechanism to prevent material bridging in the hopper, ensuring the continuous flow of material into the auger tube as well as an auger cover flap pivotably mounted at the outlet end of an auger tube. A programmable controller allows users to select between variable combustible materials and regulate grill systems, allowing adjustment of cooker elements including the auger, airflow fans, and a hopper agitator to optimize combustion efficiency and maintain consistent cooking temperatures, adapting to the characteristics of each fuel type.
