Another Happy KKTO Owner

Re: Another Happy KKTO Owner

Thanks Steve,

Are you able to put up a pic or two?
Ive had in the past the blades stop turning when it wasnt centralized. It doesnt do it when the roaster is empty, but once the beans go in, it hesitates, then i go into a panic and wiggle the pot so that the bottom of the shaft engages the turning motor, then its fixed.

Hi Gary, sorry it took so long but these are the images promised. Outside view, I adjusted the clearance by using various washers. I use three bolts/nuts spaced evenly around the pot. They are stainless bolts that came with a BBQ I brought a couple of years ago. Never thought they would be useful for a coffee roaster

Re: Another Happy KKTO Owner

Ahh thanks Steve, i understand now.
Ill try that.

Do you roast a kilo at a time on your roaster?

Yes, most times.

Re: Another Happy KKTO Owner

I noticed some have modded the TO by adding switches to control the fan and element.

A quick tip for those who dont want to go to that trouble: just lift the handle (only the handle, not the whole TO) that will turn off the fan and element.

Up to now, I have been doing a 5 minute bean warming phase after load and before turning the temp up. I tried another method on the weekend: pre-heat to 140 - 150^o. Load the beans (it should drop back to sixty-something degrees depending on the ambient temp) and then turn it up.
I got a nice constant 10^o per second ramp up to first crack. As usual I drop the temp down about 5^o before first crack to allow for lag and rather than burping, I lifted the handle for a few seconds to help it drop down. Once the proper ramp to second crack was reached, I controlled it successfully by lifting and lowering the handle.

The results seemed to turn out more even and even smelled nicer than other roasts. It even shaved a minute or two off the roast time. More trials needed, of course.

I havent tried that. Thanks.
I do turn the temp down and allow for the lag but your tip should give me more control.

Welcome back TG! Long time, no see.

I discovered it by accident but it was one of these doh head slapping moments - why didnt I think of that before? Its probably not as instantaneous as burping but the temp changes are not as drastic and you are less likely to stall the roast.

Re: Another Happy KKTO Owner

Ill also give it a try.........I thought burping was the go as it expelled as much smoke as heat [which I thought to be a good thing] I also end up with chaff going every where so this method will help that.

Steve.

PS Yes welcome back from me also. Now where is Mal  :-?

Here is a link to a "quick" video i made after modifications, namely removal of the heat shield and angling of the fan blades on the halogen turbo oven.

Chaff is blown into the pot through the holes of the strainer by the heated air flowing in the chamber, so it's basically a clean way of roasting.
After roasting, the beans are dumped to cool and the strainer hung on the side in order for the vacuum cleaner to do its job of extracting chaff out of the unit.

Flynn's method is used here just before first crack so the chances of stalling is minimized. As he mentioned before, lifting the handle serves the purpose of stopping the heat input and fan for the smooth transition into first crack.
I only lifted the oven to show viewers how the roast looks.

The roasting station is minimal, just the timer, spoon, the bottom glass to hold the oven after use so that i don't scorch the table, bean cooler and the next batch ready in the integrated measuring/scale cup (this cup is great, no need for scales, used for weighing beans before and after roasting and doesn't take up much room) for back to back roasting.
700-800 grams is the sweet spot for the KKTO to enable me to roast 1.5 kilograms post weighted beans per hour.

That looks fantastic Gary! It's a shame that you can't buy a complete KKTO setup ready to roast 700-800g batches because I would buy one in a heartbeat!

You can always ask the man himself, Koffee Kosmo regarding the KKTO. Check out his website.

You can make your own, or buy the roaster unit and buy your own turbo oven, or get the whole shebang with oven included.

I would suggest do the second option and get your own halogen light turbo oven. This kind of oven allows you to see the beans clearly as shown in the video footage.

Great roaster when you want to do another roast straightaway. Just vac out the chaff, put back the pot and away you go.

Is the Tiffany turbo oven sold by KK not a halogen light TO? What else would I be required to purchase other than the basic kitset + turbo oven?

It certainly does look very simple to use! Is it easy to hear the cracks or is the motor quite loud?

It is simple to use, and allows full user input.

I don't believe the Tiffany is halogen. It is of a heater element.

I can't hear cracks on mine due to the strength of the insulated liner and the thickness of the glass of my oven.
I use the smoke and smell as clues as to when to burp and adjust temperature. When you lift the glass of the oven you can visually sample beans at whatever stage they're in and hear the cracks.

Best suggestion is to go to his Koffee Kosmo website and ring him up. You will get direct answers in quick time.

If you have or can source a set of the preferred 24cm Arcosteel pata pots ** even if second hand pots are utilised **
You can have the KKTO roaster built in less than an hour
If your DIY skills are lacking and if you supply the arcosteel pot set, we can build it for you
Other pot sets will work but may require some changes to the agitator blade ect

Sponsor Barazi have all the kit parts in stock they also manage sales through the Koffee Kosmo web site
Emails of a technical nature are forwarded to me to answer

P.S. Gary has a fully assembled roaster by me
See his testimonial of the web site
