Material: The cold smoke generator is made of stainless steel for durability. Applications: Smoked coils for smokers, ideal for cold smoking a variety of foods such as salmon, sausage, duck breast, filet mignon, pork, chicken, cheese, fish, and more. Suitable for most grills. Design: The surface of the generator is perforated for better air circulation in the sawdust. The spiral shape allows slow combustion, flameless operation, and does not require an external heat source, enabling extended use. Use: Easy to use—simply fill the spiral with sawdust and ignite with a lighter, tealight, or sawdust igniter (not included). Note: Ensure the sawdust is evenly distributed and the top of the spiral remains visible. Economical: Compatible with various wood pellets such as cherry, pecan, mesquite, apple, beech, and others. Produces hours of smoke using a small amount of sawdust.
