Gary, Foam hit the nail on the head in post #19. Thanks, Foam.
Got a question. I put a 6" AMNPS tube with hickory pellets and ran a trial run at cold smoking (no Heat) on my 30” analog. Got full smoke for the entire 2 hours. But the smoke was a thick gray and it left creosote all over the inside. Would adding a vent at the top solve the problem? Any advice would be great.. Thanks!
It is very difficult to achieve TBS while cold smoking. The temperature of the fire is just not hot enough.
You want to produce a thin layer of smoke, not a fog, and pass it over your food quickly. I open all my vents and will even crack the door to allow for more oxygen in and out of my smokers
The Tube Smoker can produce a lot of smoke for a small cabinet like the Masterbuilt Analog
Decrease the amount of pellets used and increase the airflow thru your smoker. I only use the Tube Smoker 1/2 full with pellets during cold smoking
Colder days will also produce a more dense smoke. Think of it like fog in a swamp. The cooler temps of the lower areas will condense moisture and create fog. The same thing happens when cold smoking in colder temps. The temp of the smoke is not high enough to rise out of the smoker quickly.
Some guys use a mailbox mod with great success. I always open the exhaust vent and crack the door for more airflow. It doesn't matter if it's a MES, Pellet Grill or one of my other smokers. Airflow in and out is very important
