Cooking devices with secondary smoke generation
A cooking device including a cooking chamber comprising at least one cooking surface, a wood pellet burner positioned below the cooking chamber and configured to combust wood pellets and provide a first source of smoke, a wood pellet hopper configured to store a supply of wood pellets, an auger configured to feed wood pellets to the wood pellet burner, and a secondary solid fuel combustion unit removably inserted into the cooking device below the cooking chamber and configured to combust a second solid fuel and provide a second source of smoke.
1 . A wood pellet grill with secondary smoke generation, the wood pellet grill comprising:
a cooking surface comprising one or more cooking racks;
a wood pellet burner positioned below the cooking surface and configured to combust wood pellets and provide a first source of smoke;
a wood pellet hopper configured to store a supply of wood pellets;
an auger configured to feed wood pellets to the wood pellet burner;
a secondary solid fuel combustion unit removably inserted into the cooking device below the cooking chamber and configured to combust a second solid fuel and provide a second source of smoke, wherein the secondary solid fuel combustion unit is removably inserted into a receiving aperture integrated into the cooking device and configured to receive the secondary solid fuel combustion unit;
a hot rod tube integrated into the cooking device and configured to ignite the second solid fuel within the secondary solid fuel combustion unit.
2 . The wood pellet grill of claim 1 , wherein secondary solid fuel combustion unit comprises a pellet tube.
3 . The wood pellet grill of claim 2 , wherein the pellet tube is rotatable within the receiving aperture.
4 . The wood pellet grill of claim 3 , wherein the pellet tube comprises a plurality of holes distributed along a body of the pellet tube and wherein rotation of the pellet tube alters an airflow through the pellet tube.
5 . The wood pellet grill of claim 3 , wherein the pellet tube comprises a dimple that protrudes through a slot in the receiving aperture, the slot being shaped to restrict movement of the dimple beyond a predetermined angle and prevent further rotation the pellet tube.
6 . The wood pellet grill of claim 1 , wherein the hot rod tube is further configured to pass through the wood pellet burner and ignite wood pellets in the wood pellet burner.
7 . The wood pellet grill of claim 2 , further comprising:
a burner housing enclosing the wood pellet burner; and
one or more openings in the burner housing configured to blow air onto the pellet tube and thereby keep pellets within the tube smoldering.
8 . A cooking device, comprising:
an external housing;
a cooking chamber within the external housing;
a wood pellet burner positioned below the cooking chamber and configured to combust wood pellets and provide a first source of smoke;
a wood pellet hopper configured to store a supply of wood pellets;
an auger configured to feed wood pellets to the wood pellet burner;
a secondary solid fuel combustion unit removably inserted into the cooking device below the cooking chamber and configured to combust a second solid fuel and provide a second source of smoke, wherein the secondary solid fuel combustion unit is removably inserted into a receiving aperture integrated into the cooking device and configured to receive the secondary solid fuel combustion unit; and
a valve disposed above the wood pellet burner and below the secondary solid fuel combustion unit, wherein the wood pellet burner is further configured to combust the second solid fuel in the secondary solid fuel combustion unit when the valve is in the open position.
9 . The cooking device of claim 8 , wherein the valve comprises a butterfly valve and further comprising:
a handle on the external housing configured to actuate the butterfly valve.
10 . The cooking device of claim 8 , further comprising:
a housing configured to receive the secondary solid fuel combustion unit, the housing comprising a ceiling configured to seal the secondary solid fuel combustion unit when the secondary solid fuel combustion unit is completely inserted into the receiving aperture.
11 . The cooking device of claim 8 , wherein the cooking device comprises a smoker and wherein the cooking chamber comprises a plurality of cooking racks.
12 . The cooking device of claim 8 , wherein the cooking device comprises a pellet grill and wherein the cooking chamber comprises at least one cooking rack.
13 . The cooking device of claim 8 , further comprising:
a drip tray configured to route smoke produced by the wood pellet burner and smoke produced by secondary solid fuel combustion unit to the sides of the cooking device.
