  • Patent number: 11208604
    Abstract: Described herein is a method for isolating high carbon chipped wood charcoal fuel suitable for grilling food. According to one aspect, the method involves removing pyrolyzed wood charcoal from a kiln wherein the pyrolyzed wood charcoal comprises lumps, chips, smaller pieces, and dust particles. The pyrolyzed wood charcoal is passed over a first sieve that is configured to separate the lumps from the chips, smaller pieces and dust particles. The chips, smaller pieces and dust particles are then passed over a second sieve that is configured to separate the chips from the smaller pieces and dust particles. The resulting chipped wood charcoal is consistently sized to be small enough to pass through a food supporting grill grate and supportable by an underlying grid support, thereby allowing refueling while grilling without interruption.
