The smart-smoke technology in this grill uses an automatic electric feed system that is able to maintain a constant temperature from 180 to 450 degrees and has a hopper that can hold up to 20 pounds of pellets for extended cooking time. The digital control also handles igniting the pellets while fan-forced convection results in even cooking all around, much like rotisserie-cooked foods.
Pellets are made from different woods, each of which imparts a distinctive flavor to the meat. Hickory, oak, maple, alder, apple, cherry, hazelnut, peach, and mesquite are among the flavors available. For more about pellets, read my article, The Science of Wood.

One of Yoder’s most unique features is the Variable Displacement Damper. This makes it easy to smoke, sear, and grill your food using the YS640.

If you move it back to the right, the heat will spread evenly across the entire some box for even cooking. The unit comes with a side firebox which has a removable cooking grate if you want to grill your food in it.
