Fluid bed roasters dissipate the smoke much faster compared to drum roasters. I used to use a small fluid bed with some concertina tubing and a lot of filters to pipe the smoke outdoors. That tubing got very dirty. I never saw any smoke from it. But you can smell it and it’ll trip your smoke detector.

I’ve never heard of any one recommending the oven as a first attempt. Usually it’s a pop corn maker.

I’ve used several home roasters. Getting one with an afterburner is the way to go unless you have extremely good ventilation or powerful range hood that vents outdoors.
