Disaster??During a roast on my KKHG the agitator begun to seize and eventually stopped.Thankfully the batch had completed. Pulled apart and found the drive shaft has never been fully inserted into motor.Pulled same apart and and with tools repaired damaged drive.Gave KK a call re new motor and after a catchup he offered some parts for pickup to facilitate my refurb.This done by Grandson and a trip to Jaycar plus spade terminals and tool from son i now am back roasting.Many thanks to Paul (KK) and my family.

Bad luck BC, pleased to hear you got it sorted out, ain't it great to have caring grand kids? :thumb:

While waiting to complete my new fluid bed roaster I have been tempted to push the KKTO a bit harder to see what it can really do. My demand is such that I really need extra roasting capacity now!

I have pushed it up to 1.2KG greens to give me 1kg roasted!

Mine is modified with the thermostat bypassed and just the heater switched thru the handle and perforated plate on heater removed.

To my surprise it handles it with ease, roast length is obviously a bit drawn out, but it only needs a burp to get over first crack and then a few burps thru the time between 1st and 2nd crack to maintain the RoR i want. I am getting a lovely decreasing RoR thru the whole roast and getting around 25% development time as per Rao.

Beans are actually more evenly roasted thru the whole bean as a result and the taste in the cup direct from the roaster was amazing!

I think mentally I always held back from pushing bigger loads because I was concerned about the roast time being too long, having broken that barrier was an interesting epiphany!

Its amazing to think what this marvellous invention from Paul is capable of, a 1.2kg roaster that cost under $800!

The new fluid bed, Rocquette Roaster has a lot to live up to, but if it can match the KKTO for roast quality and punch out 2.5kg roasts then it will be a success.

I'm getting 16 minute 1kg roasts (excluding 5 minute stabilisation on Thaw setting).  This is because of the Kogan Turbo Oven which seems to have more juice than any of the others I've owned.  I'm having issues with 500g and below roasts being a bit uneven because I've not yet leaned the new TO.

I'm finding that for larger roasts it's best to remove or take away by cutting most of the steel of the deflector plate in front of the element

Normally I don't advocate the full removal for element safety reasons

However the practical reason for this is mod is that the TO will not cycle ON & OFF as often and mainly stays ON
I believe that the fan deflects hot air upwards from the deflector plate and activates the thermostat more frequently
When there is no deflection this ON / OFF cycle in minimised

I do 1.2kg batches on mine, but it was only possible with the removal of the shield as KK describes - and also bypassing the heat switching. I had an electrician mate wire mine so the handle microswitch turns the heat on and off while leaving the fan running. (to turn the fan off i have to switch the TO off.)

Its a bit Heath Robinson, but getting 1kg of roasted beans per batch makes it worthwhile.

As galumay has noted that he roasts 1.2 kg on the KKTO

I have also done this as well with good results
However I use a standard TO so I do a stabilising pre roast to help the roast reach good crack times

I really should see if I can enlarge the design to be able to roast 3 or 5 kg
Getting the right amount of heat is key

Fear not KKTO fans - I have been thinking of another hybrid heat supply design using gas flame and forced air symilar to fluid bed designs for 3 to 5 KG roasts

All these design juices were flowing when Galumay and I were discussing fluid bed roasters the other day
