DIY Coffee Roaster - (Larry Cotton Design)

[@Mike-fu4bc]

Hello ! 👋 I'm roasting coffee from 2018 or so .. I've use some German machine ( not expensive ) but didn't work like i would do because my voltage energy supply.. now I'm using a Gene Cafe CBR 101 and quite satisfied ! I'm also planning to make my own roaster ! Just some advice for you if u can take.. you are roasting in to second crack and 4 sure u get some oil over the beans.. U may like that but try to make 1 batch with 1st crack medium dark and see the difference.. to not become oil coffee.. see if u like it .. and also i have a cooling made myself that in center i have little bar metal spinning with some help from a motor and it's connected to a vacuum very similar like u have and my coffee gets cold in 1-1.5 minutes ! Sorry if i mistake some words.. English It's not my primary language !

Nice set up. I plan to make something similar.

Good video! I was also unsure about wiring the screwdriver, the instructions were unclear

[@LawrenceCotton]

observe how the batteries are polarized (+ and -) in the screwdriver then copy that polarity to a 120VAC to 12VDC, 500mA adapter (transformer).

Looks so good! How is the flavor compared to other roasting methods?.

[@LawrenceCotton]

same if same bean variety; times will vary somewhat depending on ambient

@@LawrenceCotton I got The Hive Roaster with the electronics, I haven't tried it yet.

That's cool with the wheel you don't use any thermometer for monitoring temps?. I made mine with paddles. Now i have a Kaldi Fortis 600g drum the coffee tastes much better 8:37

[@LawrenceCotton]

i've used a thermometer just to see what the beans get up to--around 450-480F in ~15-20 minutes, sometimes more in chillyn weather.

Awesome work! I also built a wobble disc roaster myself though I used a JGY370 worm gear motor. This is my setup though in this video (kzbin.info/www/bejne/aKDXo32Yn6eemrs) I used metal spoons embedded in the shaft instead. This has since been modified to use a wobble disc made from a tin can lid. This is a great roaster and I can roast 200gms in under 10 minutes!
