Roasted 625gm today.  I preheated at 250 degrees for a good 10+mins.  I got distracted making pizza dough, and then the phone rang.

I put the beans in, roasted and it was a nice roast, pulled just on the first snaps of SC around 18mins.  Very happy with it.  It seems a preheat is what it needs.  I've had 600gm roasts heading for 25mins without hitting SC before and always thought that was a bit slow.

So there you go, still learning. :)

I am very excited to welcome to the world my new KKTO.  KK, you are a legend given that all you've put into this roaster you continue to share the journey and mods and the plans with enthusiasts like me.  Will the Behmore retire... probably not but the maiden roast was a Robusta and tasted so good out of the roaster that I am gobsmacked!!!

I gain just as much pleasure from this new addition the KKTO club as yourself  ;D
And I am always available for advice and encouragement

Just some points to remember
Keep the total volume to a max of 9 liters
1) You will need a false floor or an insert from the KKTO shop + insulation
2) Use silicone tube to seal in any heat escaping and you will have a roaster to be proud of
If you are married it will save it, if not? a future Mrs Brett H will be impressed  at how clean it roasts

Thanks Nic and Paul.  Marriage saved!  I've used a silicone bake wear cake mould cut out for the top of the pasta insert where the TO sits. It is a reasonable seal but not a perfect one. I insulated under the pot between it and the table for heat retention. Do I need a false floor also? I have a stainless pan perfect size that is for the dump (glass lid was smashed years ago and could never bring myself to throw it out) that would be light work for the grinder. Should I insulate under that also?  Thanks for all the help and the inspiration. Happy days!!!

If you want to get to the batch size that KKTO owners get, the answer is yes to a false floor and insulation in the cavity

My insert is made to have the correct volume when fitted to a depth on 10mm from the pot lip and engineered to have an air gap on the sides for added insulation
For the air gap functionality, tests show that the temps inside the roaster can be 250 + C and outside its 80C  
It will fit any 240mm pasta pot set

I have seen them in The General Trader at Jindalee DFO.  They'd be worth a call.  If I find any firm availability I'll PM.

Well... After listening to what other folks have been saying about their roast times on the KKTO - and after some sage words of advice from Mr KK himself - I bit the bullet and bought a new turbo oven - as it seems that my old one was not up for the job!

And what a difference a day makes! New 1400w halogen turbo element combined with some lovely Bali Danau Batar - and I'm up and running !

Was too excited to do my usual preheat - so I cranked around 700g of beans to 250C and ramped them till first crack at the 20min mark - then dropped the temp back to 200C and pulled the roast at about 20sec into second crack - at the 24 min mark

I susspect that had I started with the preheat that i would've shaved a few minutes off the roast time - but even so 24mins is a great deal less than the 30plus mins I've been working with - and it's great to see everything cranking much earlier than what I'm used to

Now to try the coffee as a filter at work in the morning to see if it lives up to expectation!

Dont forget to use the high temp silicone tubes when the set arrives
Also dont use the adapter ring and the times will come down under 20 min

The design parameters of the KKTO is for the liner to reduce the volume so all available heat is used from the Turbo Oven in the most effective way for coffee roasting
The liner is fitted inside the outer pot and is an important multi function part that acts in 4 ways

It safely contains the insulation
Insulates by a measured air gap on the side
Reduces the overall volume in the roast chamber
It achieves the correct volume matched to the available heat produced by the Turbo Oven

I find with my unit that if I use tha Thaw setting for preheat then it doesn't take the preheat bean temp up o 50degC.  Does anyone else have to use a setting higher than Thaw to get to preheat temp?

If you do a KKTO stabilizing pre roast (with beans) you can go as high as 125 deg C for a short time
Then "zero" the time once pre roast is completed and start the roast proper

If you pre heat the roaster (without beans) you can go as high as 250 deg C

Have well and truly joined the KKTO mob.
Roasted 4 kg since getting it set up.

Wrapped with fire blanket and bath towel.

A photo here of the first roasted batch of the Ministry Grounds House Blend.

Tastes great and pours nicely after a 3 day rest.

Using a Homewell Halogen turbo oven bought from Homeart for $39.50.

Getting 1st crack at 17-18 min, 2nd crack at 25-27 minutes, though i'm reassured the slow long roast has resulted in a smooth and well flavoured cup.

Due to the seemingly long roast times, i use KK's advice of pre-heating at 250 deg for 5 minutes, then add beans and use full power all the way til the end.

Could not hear first or second crack, and had to use visual to gauge what stage the beans are.
Hoping to sort out the DMM logging sorted out if anyone can give me the link of the spade connecting probe.
I don't fancy drilling a hole thru the side for the stainless steel probe, prefer to use the spade type fed from the lip of the roaster.

So far very happy with the results of this roaster, though i'd like to learn more about getting the best out of this.

Hi Lacehim,

I'm currently doing 600gm greens to get 500 gm browns so that they fit in the 500gm one way valve bags.

If i;m going to do multiple roasts, i will try the recommended optimum size of 700gm greens.

Btw, i'm not a gal, so sorry to disappoint you  :D

Kelsey, i was in the same boat as you, so i understand what you're going through, but eventually those feeling will be long gone when you get your hands on them.

Took a look at aldi TO's, today.

Now I understand how the TO is mounted on the main pot and why it is smaller diameter, I wonder if it wouldn't be easier to:
buy an aluminum pot of correct  diameter
remove TO unit from glass pot lid it comes with
Cut a hole in the metal pot lid
Remount TO on this

a sight glass and bean testing scoop would be useful while cutting things, but I rarely roast by sight these days.

Not sure of your minds eye
Do a drawing so I can see where you are going with this

Having said that - I have designed a reducer / adapter ring
