KKTO Hybrid

derrilex

And then this crops up. Some of these mega beans are charcoal, some are ok but the size difference and the fact that the smaller bean is well underdone tells me something is not quite right

I had this hassle when I went up in volume without adequate agitation. I fixed it by trial an erroring a bloody disasterous looking agitator but darn it if it isn't the business. Even roasts from 400g - 1000g. Stainless steel and copper... behold with horror:

:rofl: :rofl: thats wild Brett. Just as mad as some of my creations. Stay tuned for more insanity :tearhair:

Finally, finally came up with a agitator that works. Thank Christ.

If it works who is complaining! 🙂 The most important bit though, how are the roasts in the cup?

I will see if I can dig up anothe Pre-used drive shaft (fingers crossed) As this one in the photo has seen better days :pan Let's give this design a few roasts and see how it performs :thumb: It's all fun with trial and error KK

Mate, clearly I have got nothin' when compared to your wacky spring spinner of doom. Is it an agitator? Is it art? Is it a cry or help?? NO... it's bloody brilliant! :thumb: :coffee2:

Works like a mother Brett. The previous one worked great on a cold test with 600gms of beans but when everything was preheated the beans just got pushed around as one mass ??? Got me stuffed. So the spring was born. Had to heat the spring at the end to bend it. Proceeded to touch red hot spring and branded myself :head: Ahhh C'mon KK, that shaft is perfect. Many holes make light work of securing bits and pieces :rofl:

Lacehim, I haven't tasted any with the current spring aggi yet but previous roasts have been pretty good. The first COE was excellent, the second blended with yirga was also very good. Currently going through some yirga /MM blend. So all in all I'm really happy with what the hybrid can do and now hopefully I'll get the consistency. :thumb:

:rofl: AM, yep Ive got some bits and pieces hanging around including this MM just done. http://s1174.photobucket.com/albums/r603/derrilex/roaster%20vid%20test/?action=view&current=VIDEO0030.mp4

I've made a few mods to my KKTO myself recently - found this adjustable turbo oven at the local store:

askthecoffeeguy

tried modifying it and my KKTO to get it all to fit in the end I just whipped the top off by unscrewing stoppers at the end of the adjustable arm and placing the lid on top of my KKTO with a silicon ring as a buffer underneath:

askthecoffeeguy

first roast was a beaut but the heating element kept cutting out as it registered that it had came up to temperature quite quickly (which it had) - which elongated the roast time a bit but the coffee came up really well and very evenly roasted also I'm guessing that with all those buttons to play with I ought to be able to get a 'continuous roast' - will keep you posted thought it would be cool if I could get my KKTO to fit into the existing structure of the frame of the turbo oven - but alas this was not to be despite my nest efforts might be possible with a cutting wheel and a welder to pimp it all up a bit but in the end just removing the lid (and extendible arm which is necessary for the element to engage) and popping it on top of the KKTO was the simplest and most effective result I like that I now have direct heat right where I need it (as opposed to the adapter ring that suspended the heating element above the pot on the original prototype KKTO), and the airflow seems to be very good due to much bigger vents - which can only be a good thing! watch this space! Cheers, Pat

Thats a wild looking piece of gear Pat. So many buttons ^-^ Ps, get ya own bloody thread :rofl:

I did think about that but I hate double handling 😉

I know the feeling ;D

600 gm of yirg. Happy enough but a bit concerned with some unevenness. A lot of false starts to first crack and 2nd C was barely audible so I just went on colour mainly. 1stC @ 14.20, 2nd C ( I think) @ 18 ish, pulled at around 18.30
