Yet another turbo oven roaster

My one is based on a Turbo oven with stainless steel pot that is used as the outer container. I wanted a better method of getting the beans out so I have used a fixed inner pot and the whole assembly tips to remove the beans. Gary gazza attached the following image:

Can you post a close up of the arm assembly when you get a chance? I see so many things here I could use to improve my setup..Thanks --Jack ---Jack KKTO Roaster.

I have been thinking of adding some type of hanging system that I can quickly use to cool the TO and get it out of the way. Great work!

Newbie Posts: 13 Joined: December 02, 2011	Thanks for the feedback guys. Quote I like the stirrer arm design. Can you post a close up of the arm assembly when you get a chance? Here is another photo of the complete blade assembly but I'll have to pull it out to get some photos of the individual parts. It was done as a way to test different mixer blades but the first one worked OK so I have never tried any other shapes. BTW, I have just read the old post from 'farmroast' about his TO roaster and realised that there are a few features in common. Gary gazza attached the following image:

Newbie Posts: 13 Joined: December 02, 2011	The motor is a power window motor from a 1988 Mercedes 300SEL !! It rotates CCW which is the same direction as the fan in my TO and it does about 75-80 RPM. Gary

1/2 Pounder Posts: 295 Joined: December 20, 2006	Agitation is the key to good roasting results. I was never satisfied with the stirring approach. Once I went high speed 150-220rpm with the simple bean bat concept my main issues were solved. Ed B. DreamRoast 1kg roaster, Levers, Hand Mills http://coffee-roa...gspot.com/
