forced air smokers are used in commercial applications.... great drying... great eveness of smoke and temp and humidity....
If you are just concerned about jerky, look at SausageMaker D-10 forced air dehydrator... I have one and it is awesome.... pricey but AWESOME....
No but I have been thinking of a way to circulate the air inside of my smoker. This would help keep the temperature even from top to bottom and help with removing moisture when I want it removed. I need a small 110 volt fan that can withstand temperatures up to 240 degrees haven't found one yet that is small enough.
1. It will not have much effect to your smoke generator. The fan creates no added air pressure inside the smoker.
2. One of the problems I see why people have problems keeping AMNPS lit is the lack of air, or air movement. Your fan will significantly improve that condition. My smoke generator takes a few seconds to be lit, and it can keep burning for over 24 hours even at the lowest setting and using not too dry pellets. because my generator has forced air for burning.
I am not sure that is a true two speed fan. That is a shaded pole induction motor, which is line frequency dependent single speed motor.
Ive never seen a two speed induction motor but it has three wires coming from the coil. My only guess was that they tapped the coil, that would explain the third wire . doing that should reduce the the magnetic flux generated and affect the speed. I haven't run the motor yet though.
Curiosity got the best of me so I cut the plug end off that motor and stripped the wires and yes it is a 2 speed fan. So while I was out their playing around I started up my smoke generator while running the fan. Looks like this is going to work out great. When I opened the door it wasn't one big thick cloud of smoke billowing out. It's hard to explain I could see to the back of the smoker right away, before It would take several seconds for the smoke to clear. The smoke is evenly distributed and not as dense. I can't wait to make some jerky or something to try it out. The way it moves the air around, I should have even heating now.
