I am wondering if someone knows a source* where you could buy the Aillio exhaust adapter ‘A’ from metal instead of some kind of plastic.
I do already own the 3D printed model but that was almost melted while seasoning roasts.
Now when I am roasting some smoke goes alongside and fogs the room.
This adapter should also be producable on a CNC milling machine, shouldn’t it?
*A source from Europe or sending to Europe would be great!
The cost of producing a metal exhaust adapter would be prohibitively expensive. I work with machine shops and have owned CNC machines.
From what I have seen on these forums, most people are not using the adapter that attaches to the Bullet.
As an alternative, You could make an adapter as several people have done by using a metal bowl or funnel and modifying it. It should not be physically attached to the Bullet.
The online manual shows their reccomneded setup with a gap between the Bullet and the exhaust collector.
I use the exhaust adapter with a short (2 meters) flexible hose ( 80 mm) running out straight of the window.
That works wonderfully with the exception that the plastic exhaust adapter ‘A’ has been melted.
I have made my own little thingy that attached to my exhaust pipe.
It’s a aluminum funnel that I reshaped the pointy end of and attached to the bullet with aluminum tape.
Its not pretty but super efficient and low cost.
Note: The red thingy is just a silicone ring to make a better seal when connecting to exhaust pipe and the small white cord is just an exhaust temp probe.
Could it be that you chose the wrong plastic? I got mine printed with PA12 at Shapeways. No signs of melting after 20kg of coffee (light, not beyond 205°C IBTS). However, my 3kg seasoning roasts went deep into 2nd crack.
I’m having a similar problem. My adapter isn’t quite so melted, but it did reshape itself. It originally fit firmly, but after heating, it shrank and now there’s a gap.
I open a window and built an insert with two openings for 4 inch vent hoses. I had to get flexible hoses so that I could easily pull the insert out of the window to close it when I’m done. The thing is, the gap at the 3d printed adapter means the hose pulls the adapter back and the gap lets smoke pour out. I spend my time from first crack to the end of my roast (I drop after hitting second crack) holding the adapter down so less smoke pours out.
I’m at my wits end trying to come up with a solution. I do not have a kitchen hood. I live in an area that 3/4 of the year is too hot or too cold to roast outside, plus, it’s very humid here. My only choice is a window. So my hose goes down then laterally to reach my window. It’s only about 2 feet of hose.
The bullet really should have been made where it didn’t just have an opening, but that single piece molded to a short 4 inch circular tube. Appearances be damned. The current design doesn’t work for a significant portion of their customers.
Having users trying to fit this odd shape with 3d printed solutions that shrink, deform and leak is a poor solution. We don’t all have kitchen hoods, vertical routing options (that won’t pull a loose adapter to one side) or the ability to do permanent venting installs.
