Good day all. I wanted to put together a DIY jerky drier for my 3.5D. I had some parts laying around so I hacked this gem together.
I mounted a DC power supply and a PWM controller on top of a blower fan. The fan sits atop a soup can that will sit over the exhaust port. I will be drilling the proper size hole in the bottom of the can to fit the smoker exhaust port.
I am going to use JB Weld or perhaps just silicon RTV to secure the fan to the soup can and use magnets to hold it down over the smoker exhaust hole.
I got the incorrect fan for PWM use so I added a diode and capacitor to make it work. Not great speed control now but it will be sufficient. Replacing the fan with one that will accept PWM control will be a future update.

That certainly looks like it will move some serious air.

It will. It is a centrifugal blower so it should create a good vacuum.
I added the PWM to tailor the airflow. I would probably turn it lower as the jerky gets drier.

The 120v axial fan I used doesn't have speed control but it is AC and plugs directly into an outlet so no adapter required. And the speed/CFM works great for me.
-
Do you know what the CFM of the fan is? Also, I have better access to DC fans so I prefer to use them. AC fans are quite handy though.

Well, first attempt was a failure as magnets don't stick to non-ferrous metal. DOH!
??? ::) ;D
Seeing as magnetism has failed me, I will be going to try and use gravity to do the hard work.
I am going to make a sacrificial mold and fill the can with mortar. That should provide sufficient mass to hold the can in place.

The AC Infinity fan I use is 23 cfm, 2000 rpm. And it is very stable using the PVC cap as seen in my post.

Forgive my clumsiness on this site I am a bit new. I could not find the picture of your set up. :-[
Can you help me out?

Here are 2 pictures. The second one shows the slot I cut in the base for thermometer cords.

Gave me drier a try last weekend. It worked quite well.
I don't think I needed the speed controller on the fan.
-
Congrats!
-
Excellent! Looks great!
As for the sturdiness, I also used heavy PVC as my base for my fan, just like what Lonzino has shown.
-
I didn't have any proper PVC on hand so I went with my next best option. A Mason jar lid.
It worked surprisingly well. I was amazed to see how much steam blew out of the cooker when I first energized the fan.
