Smoke issue

Roasting on the Bullet
1

Hi there, I have been roasting under my hood vent for about 2 years now and it’s been fine. I’ve just cleaned my machine about 5 days ago and i have noticed that more smoke is still coming out of my machine way more than it ever used to.

I have some videos attached here:

Smoke coming out the side: https://youtube.com/shorts/cKJkMxuccq0?si=7a2UpKbphBTdabuD

I know obviously there’s going to be smoke but now it seems very excessive. For reference I am using a double washed coffee from Mexico and my preheat is 230c. The room temp is 77f and the room humidity is 40% and the batch size is 600 grams.

Would anyone be able to help me figure out this issue? It gets sooo smokey when I roast now.

Thank you!

That’s super Smokey. Is your fan in your squirrel cage running / installed correctly? That almost looks like it’s clogged or something. If the impeller isn’t moving maybe double check you hooked all the connections back up if you had taken off the squirrel cage.

Thanks so much for the response. It is running and installed correctly, however it looks like it’s spinning counterclockwise now if that makes any sense.

When I drop the beans into the cooling tray an insane amount smoke pours out too.

Something is obstructing the airflow, surely. Check your exhaust tube starting from where you charge the beans to the back of the roaster. Once you remove the chaff collector, use a flashlight to see inside. Check this thread.

Also check the faceplate. It might not be screwed in properly. Maybe the cable was pinched reinstalling it after cleaning, and it stopped being airtight. Check if the screws are tightened all the way.

Check if the exhaust fan is really working.

You may also want to put your hand above the fan to see if you feel the air being expelled.

Also, soak the chaff filter in some baking soda or Cafiza. If you’re using baking soda, bring the water to a boil, turn off the heat, put in the filter and add 2 teaspoons of baking soda. If you’re using Cafiza, don’t let it soak too long as it might damage the filter, A minute or less will suffice.

Once you’ve checked all that, if you haven’t had success, although I hope you will, post here so everyone might think of something else and help you with other suggestions.
