I have an electric Masterbuilt smoker. For bulk smoking, I've had good luck using disposable aluminium roasting pans.
Pans are disposable roasting pans of whatever dimension will fit in your smoker and of about 6-8cm depth.
1- Poke a bunch of holes in the pan. I use a blundt knife and stab-n-twist away. Plunge the blade through the foil tray (from the outside towards the inside, it just works better that way) and when the blade is embedded in the tray, give it a little twist to make the opening a little larger. Poke the sides and the bottom. If you can get holes on about a 3-5cm on center (that would be 1-1.5" oc for us Yankees)..that allows a good amount of smoke through the chiles (that's chilli's for the rest of y'all)
2- go ahead and fill the roasting pan up with washed, de-stemmed and cut in half pods
3- smoke low and slow as the others have said using whatever you want for wood, heat, time, etc.
4- after 2-3 hours (depending on the heat, wood, desired smoke-i-ness) etc. the pods are smoked, limp and ready for whatever you want to do from there.
Dehydrate, freeze as is, grind then freeze, make a sauce, ...treat them like you would any other fresh pod in how to preserve or use the chile flesh/pod.
Have Fun!
