Gravity Feed Charcoal
These are another “automatic” kind of BBQ smoker, they can have a controller or be completely manual.
To work, the fire compartment and hopper must be airtight, the fire is lit at the base of the charcoal in the hopper and vents into the cooking chamber from one side.
Air is provided to the fire through a regulated inlet valve or a digital controller and fan.
Wood blocks can be placed in the charcoal load, or under the fire in the ash pan to provide extra smoke, this allows you control over the smoke level.
Wood burnt in the hopper provides “raw” smoke to the cooking chamber.
Wood placed in the Ash path smoulders when small pieces of charcoal fall from the fire, the smoke is forced through the fire and “re-Burnt” like a catalytic converter, this cleans up some of the impurities in the smoke for a sweeter taste.
You can use either Briquettes or Lump Charcoal
