hey everyone. i am ready to get into home roasting but i am trying to determine if i am crazy for attempting it. i live in a condo unit with no garage. i know it is probably ideal to roast in a garage because of smoke and smell. do any of you roast indoors with either the behmor 1600 or the freshroast sr500? I am not as concerned about batch size as I am about smoke. also, how bad is the smell? does it linger?

I absolutely love the smell of roasted beans,but I've never done it. We don't want to risk setting off the smoke alarms, right? BUT You might want to try out roasting a small amount first. Cause some users won't mind of the WONDERFUL smell of roasted beans, while for others...well it's TOO overwhelming.
Try Behmor 1600, as I checked, it has a feature of smoke removal. I think it'd be best to borrow from a friend to check if it would work out in your location.
Did you know...? Dark roast coffees actually have less caffeine than lighter roasts due to the fact that the process of roasting burns off caffeine. www.coffeeloversmag.com/theMagazine

Amount of smoke depends on two things; size of load roasted and how long the beans remain in the roaster after first crack. A good home-sized stove vent (one that actually goes outside) will do a good job on roaster loads up to 500 grams. Cat converters scrub the smoke, but leave an unpleasant odor.
If you have a good dryer vent, this might work. But many apartment dryer vent systems are a tangle of plastic that might melt, so check it out:

I tried roasting inside with the behmor once, the first time I roasted. I will not try again, as all the carbon monoxide and smoke detectors went crazy, even though the roaster was just under the stove vent. I was only roasting a quarter of pound.
If you do decide to roast inside anyway, make sure to have a carbon monoxide detector, and know the symptoms of a CO intoxication: dizziness is probably the first of them. If it happens, press the cool button, and go outside.
Indeed the behmor has a smoke suppressor. You can barely see any smoke, but it is still there.
I did indeed. It's a long video, but quite an interesting fluid bed system. - Nice to know there's someone out there making a hobbyist level extractor cyclone for the home shop. 5 to 900 cfm sounds just fine - And I can use it for my wood working gear too!
I roast in a very large garage by volume with a 2lb batch size machine that is exhausted outside however when dumping the beans a good amount of smoke enter the room. The problem occurs after two to three hours of roasting, I will get nauseous and dizzy and a break is mandatory. I am looking into large air scrubbers to clean the volume of air in the garage since directly venting the air is a problem for the extreme cold and extreme hot and don't want to draw in outside air during the extreme seasons.
