 :thumb: Much appreciated to your assistance gentlemen.

Will try the masking tape trick and post results and perhaps some pics.

Just to cover all angles, i might just do a couple of vertical and a couple of horizontal slits.
Or, maybe do some diagonal ones to cover the angles (sic) too.

While the KKTO was warming up and then stabilised, i too readings in the roasting chamber using a temp probe.
It seems for eg. the dial says 225 deg, the reading on the DMM says 250.
Has anyone tried temp readings and found it's not quite the same as on the dial.

Absolutely.  All of these things measure by different ways and from different places.  Replaced mine I have not because the Force I use!!

And how much coffee do we have to give you to get ours with that mod AM? ;)  It's the one limitation for me for any volume over 500gm, that element is always on and off like a yo yo and the time just spirals out. :(

Another point is that while the halogen elements cycle faster and spike the temperature more, they certainly roast 600g fairly easily if you remove the shield completely. Not sure this is advised given that they are essentially hot glass under pressure to expand.

> If you really hate the reducer ring, you can balance the T/O on the pot set using teflon hose with a slit cut in it, but this isn't ideal as the reducer ring means the T/O rests on the metal edge rather than the lid glass.

It's an excellent mod and I routinely do 1 kg batches with mine (halogen).

As AM said, set and forget until approaching 1C.

That said the mod is a lot of stuffing around and the 240v will fry you if you get it wrong..

KKTO - Silicome hose
« Reply #87 on: 14/10/2013, 07:01 PM »
FYI - good deal on silicone hose (Operating temperature: -40Deg C to +220Deg C) in blue or black.

If you have one of the KKTO kits based on the Baccarat pasta pot set, the 11/6mm hoseis good for the top rim while the 8/4mm is good for the gap between the outer and inner pots.

I got a live demo of the KKTO from the inventor himself today. Wow...YouTube video does not give it justice.

15minutes later with Costa Rica beans he never roasted before the result was outstanding.

Commercial even look roast for sure.

Thanking you KK... Your time and devotion is very much appreciated.

I will now learn/practice my roasting on the Baby Roaster until the new KKTO V2 is developed.

You were a good student and most welcome
Did you notice that I let the roaster do all the work and we just made and tasted coffee from the Strega while we waited for first crack

I find coffee roasting to be very relaxing ( as it should be )

So... My halogen Kmart oven isn't generating enough heat so... Off to Aldi to try an old-fashioned stove element turbo oven.  If I crank it to 250, it'll burn the beans in a 500g load and the two subsequent roasts on 225 with a 5 minute thaw 'preheat' does a brilliant job. I didn't think this style of TO would cut the mustard but so far it's better than the  other two halogen ovens I've owned.  We'll see how long it lasts.

Let me know how you go with that Brett. After my halogen TO died, Lacehim lent me his old Tiffany non-halogen TO but it also doesn't generate enough heat - Takes over 21 mins to get to second crack, if it makes it at all!

Are those $39 KMart brand jobbies halogen? For some reason I thought they weren't.

My Tiffany TO was superb however when the fan failed after many hundreds of roasts I got a highlander brand TO with halogen element

Keep the old unit and convert it to a heat gun application - see thread I started
I will do this myself with the old Tiffany

Kelsey, the new one I have is from HomeArt.

The Tiffany was fine with the guard removed, but I like the light of the new one and it seems to have a bit more heat. :)

Hi mate, my 39 Kmart was Halogen and gutless.  This Aldi one has more headroom but heats more slowly initially... Thus the thaw setting for 5minutes.

I think mine is heading south. :(  Took 19 minutes to roast to 1st crack today, and that was with a 10 min 250deg pre-heat!  Time for a trip to HomeArt me thinks.

Yep... Both my halogen roasters still work fine albeit much longer roast times.  I wonder if there's a way to re-invigorate fatiguing elements... It seems such a waste (throw-away society)!

I will probably freecycle mine.  IT would still be fine for cooking.  We are using at the extreme end of it's temperature limit, but baking a cake or cooking a roast would probably put less stress on the element.

A couple of things to be aware of...
  • Bi-metal strip temp control has a LARGE tolerance.

    The sensor face can get dirty.

    The element connectors can fail, and if doing back to back with long runs; then this will add to early retirement.

    Internals can get dirty / oily and also interfere with temp control.

Clean and blow out with compressed air...  Until I had my own compressor; the local servo was a regular pit stop...

My Kogan Turbo oven is more than 6 months old and today I asked it to do a kilogram roast in the KKTO.  Five minutes of stabilisation at 50degC then rolling second crack 15 minutes later.  This is the best turbo oven I've had yet and they're cheap as chips especially if you grab one when free shipping comes up!  The beans were Brazilian Natural Processed and it's a very even looking roast!
