DIY afterburner or smoke filter

#1: Post by **pngboy** » August 31st, 2016, 3:44 pm

I recently moved to an apartment in the middle of Berlin and I would love to do 500g roasts without pissing off my new neighbors. I'm looking to do something simple and cheap. There are probably many of you that have come up with some nice simple solutions.

I was thinking some loose active carbon mixed with carbon filters a fan and maybe I could eliminate much of the smoke. Thanks

One can be seen with the new Bullet roaster. You could ask...

Some ideas here: Charcoal filter (reduce smoke and smell)

cool thanks. I was thinking something similarly along those lines. I'm surprised no one sells a mini prosumer afterburner or something similar with so many home roasters out there now.

Simple but not so cheap.

Thanks. That would be really nice but a little expensive.
Maybe something like this in a box with one or two pre-filters would do the job for a while.

That Israeli company, coffee tech I think, makes the cheapest solution I've seen, the avirnaki (clean air in hebrew), and it ain't cheap. But if someone ever yells at my 6lb roaster, I'd probably buy one.

I have one of those, but I think the price of the filters would make it unreasonable for coffee. Also, it doesn't move that much air, it's intended for grabbing the fumes from soldering, much less volume than 12oz of coffee.

Looks like the best option is probably just making my own little filtration system.

Will you be roasting indoors? You may remove some (not all) of the smoke with a carbon filter assembly but I doubt that you will remove any carbon monoxide. If you are roasting just a pound or less I suggest just roasting outdoors. If you roast just up to second crack you will not get alot of smoke, and if done outdoors I can't see where it would be an issue. Are there special outdoor roasting restrictions in place where you reside in Germany?
