Custom Venting + Cooling

[maplesyrup]

Long story, but I forgot to buy an exhaust bowl. As I roast in my basement, I was stumped until I went to Home Depot...

What you'll notice is my exhaust is using a 8" to 6" duct reducer, with a simple 6" vent cap for the bottom. The fan is inside the 8" section. This is 100% sealed and has eliminated all smoke (trier sampling excluded).

For the cooling, I cut a hole in a stainless Ikea bowl. I used the stand from the fan to get it to the right height and have an old vacuum that acts to cool it down. This gets turned on right before drop and captures any smoke that would escape when the door gets opened!

Very ingenious setup.  Glad you found a workaround - I may steal the idea!!!

Hey maplesyrup great MOD!
I was going to buy a squirrel cage blower for my cyclone chaff collector until i took a look at your MOD.
I used your idea I just reversed it. Mine sits on top of my cyclone and works great. I put this together in a hurry but now that I know this works i'll take it apart and refine it a bit. A very inexpensive MOD that powers up a cyclone very well. Thanks for the DYI idea. Roasting coffee is a lot of fun on the HUKY but modding these roasters is also very fun.

I really like how you made it work for a cyclone! I want to do the same, so it looks like we've helped each other!

It looks AMAZING!! I really want to make one for myself.

Thank you!

My small DIY ciclynoe setup.

Cyclone from china less 12/13 usd. Plastic Bucket 2-3 USD Nice thing about the plastic bucket is that you can see the chaff when you are approaching first crack.

Clycone is ABS plastic. You cannot let the roaster idle without the extraction fan working.

I have a cooling tray box, made from a once broken attic fan ducted to the former cleanout from the oil furnace.  The fan box, "tin man" as a good friend dubbed it, vents to the former exhaust of that heating system.  Now I cut a hole inthe roaster table to vent a second cooling tray from Mr. Li's fan bowl onto the tray of cooling tray one.  For large batches I can drop into the round sieve and transfer half into fan box 1 collecting tray and place the remnant on the fan bowl fan.  There it is all in a low tech cell phone image:
