Anyone else have issues seeing the whole window of a thread when accessing from a mobile phone? Any fixes?

Morning Ed, I haven't done any green coffee hoarding yet but am hoping the supplies don't end up like the toilet paper isles!

KKTO - My Humble Turbo Roaster
Wiz Kalita
I was going to handle that by suspending the inner chamber using slotted L-brackets, but getting some extra space from the ring is very practical.

You need to add the curvature of the Turbo Oven in the calculations

I encourage you keep as close as possible to the design principles and make small design enhancements if your skill set is capable of doing so

Any design can be enhanced but one needs the tools and the skill to do so

Keep us in the loop with drawings and photos

A quick notice for the KKTO roaster

I have had many many emails asking for me to make available a fully manufactured and assembled roaster

To that end I am willing to start production of the new KKTO if I have orders of 100 units
This number keeps the cost down

If interested - follow the link for design update information and take the survey and register your interest

Many Thanks

It would be great to see you back with the KKTO, Mr Kosmo!

Will you still be using a converted turbo oven to drive it?

Reading from the page linked above:

To keep the unit costs to a minimum the Turbo Oven won't be included


... so I think this means he is using a regular lid...

Yes a regular Turbo Oven will still be used as a heat source
However should you choose to do so one can use a heat gun

For American enthusiasts- the voltage is different - so it makes sense to purchase that component locally

That makes sense. Plus the safety concerns of removing the thermostat and other electrical modifications.

The project will only go ahead if the required order numbers reach 100 units

I will personally assemble and test all the roasters myself to keep costs down

The original design is now 10 + years old and going strong
So you can be assured that the product will be engineered for long life

Walking today in a food facility I seen a tool that spark my imagination... what a great starting hardware for a turbo oven roaster ! All you need is to find an appropriate sieve/pasta strainer and start building.
The device I seen looks identical to this, all dimensions:
https://www.lelong.com.my/stainless-s...Sale-I.htm

... but searching for "dish warmer" you can find a lot of other layouts that could give you more ideas.

That pot set idea has promise
As always one needs to stick to the volume parameters I have set down for best results

It is 9.8 liters, so in your range of 9-12, if I remember well.

The actual overall volume range including the base pot & Turbo Oven dome is
7 to 9 lt -
So 8 lt is ideal

I am using this steamer from Ikea in my actual workhorse machine:

https://www.ikea.com/it/it/p/stabil-c...-30152346/

... but mine is not a 100% KK design, rather something closer to a SCTO, my oven being flatter, and using the whole 32 cm lid size/area. You can see here in action, at the end of the cooling phase:
https://www.youtube.com/watch?v=6acgv...acgv5eyX0o

You have also the option to use this sieve:
https://www.ikea.com/ro/ro/p/ordning-...-90011829/

... that could allow for a better agitation if matched with a higher speed motor, like those from a bread machine, in the 200 RPM ballpark.
This way you could mimic a centrifugal roaster, the high speed would throw the beans laterally on the walls, and the curved bottom will help them to come back to the center by gravitation.
