I bought them both from this guy. Just received them in the mail today. Haven’t installed either yet, but looks to be a good solution:
I had some quotes locally, and, for a single piece, were higher than both the pieces together, shipped to Canada from this seller. The exhaust adapter is a little tight on some semi-rigid aluminum duct, but I’ll pick up a flexible one, and it should work just fine.
I didn’t notice brown staining on the hood vent filters on my first three roasts, but those were pretty light, just to city.
Thanks, Bill. I think I’ll give that a try especially for the softer beans, I have some Brazil that I have never been able to hear first crack just go on temp and smell.
I’ve found this thread very helpful for setting up my exhaust solution. Here’s my V1 and V2 setups. The V1 was using the 3D printed exhaust adapter, but I found that more smoke was escaping than I’d like, so I went to a hood type setup. That one is better, but a little smoke still escapes if I go to a fan speed of F4 or greater.
I do have a bit of 3M hammock filter in the line to catch dust and oil before it hits the fan, which does restrict the airflow a bit. I will probably try some of that pre-filter material some have been using, and maybe that would restrict the flow a little less. The real solution is probably to move to a more powerful 6" fan (my 4" fan is 150 cfm and not quite as powerful as an S4, which I do also own, but am using for something else). But I’m going to try and make this work with what I’ve got. Worse comes to worse, I’ll remove the filter completely, and just clean the fan more often.
Thanks—yep, I am doing that, but, I kind of just want the other system to do it all—no reason especially, other than I want to solve the problem. Also, I find 1C kind of hard to hear on the Bullet, so the less fans I have running, the better. But, for now, the hood fan runs to pick up that stray smoke.
Nope, it’s just a piece of ‘plasticore’ (it’s like cardboard, but plastic—the stuff they make lawn signs and the like out of) that I picked up at Lowes. It clips into the window where the screen normally goes. I just install it when I’m roasting, only takes a sec.
Just finished my mobile roasting unit, the funnel at exhaust is the cloud line 6in to 8in adapter.
The table is from Ikea (BROR) and I just drilled two screws to hold back wooden plate and another screw with the clamp to hold the upper part.
The consistency is staggering different than before doing natural exhaust. I usually start the cloudline at 50% at the start of the roast, 75% at yellowing and hit it at 100% at FC to stabilize a bit the flick and crash.
This thread was super helpful when I was getting my ventilation set up for my new bullet - Thanks everyone!
Now that it’s all done, debugged, and working well, I figured I’d share the final results.
I am blessed - we have a utility room with the perfect environment for roasting - countertop, false wall to hide stuff, accessible attic with an unused roof vent, good lighting, plenty of outlets, and a spousal unit that didn’t complain too much about the permanent roaster and vent mods that I made to their brand new remodeled utility room. I didn’t really give them a choice, snuck it in and and what was done was done
I ended up with a 6inch AC Infinity Cloudline S6 fan that sits on a piece of wood that spans a couple of rafters in the attic space. There are about 6ft of 6in insulated flexible vent hose that comes from the hood through a 12in dead space behind the wall (don’t ask…) , and about 4ft going to the roof vent.
I thought this alone would work OK, but was still getting leakage into the room. So I built a hood from. Thin galvanized stock. The stock was just thin enough to work with hand shears and bend against a straight edge, but still hold its shape well.
It takes up less than 3ft of counter space on my designated section of the counter. The vent works great and you can hardly smell anything roaster-ish when not in use, and that makes it acceptable to the spousal unit. GOAL!!!
I roast in my basement utility room so venting is critical to make sure the whole house doesn’t smell like a roasting factory. I started with a 4” -200 CFM and realized that wasn’t going to be enough. So I went and installed the 6”-600 cfm unit and that works great. As I already had the 200 installed I left it and use it to vent the cooling fan. So a bit overkill in the end (the 6” would have been enough) but I don’t ever worry about smoke or smells in the house…. I do have to open a window nearby for makeup air……
I’m looking for the cooling tray adapter and he has it too. Awesome!
