Koffee Kosmo Roaster

[chrisjohnmark]

Hi

Does anyone have a Koffee Kosmo Roaster? Can I get some advice on the Roast Quality, time for roasts and anything else that might help me in my decision to buy one!! I have been roasting in a corretto roaster that I made. The results have been quite good. Would I get better results from the kkr? Less tipping, ect. Any comments would be great.

Just do a search and read .......

From my point of view... The KKTO is a winner for many reasons..

But it does come down to Fit for Purpose..... And thus some may see things differently.

I have always made myself available to the CS community

If you cant find answers to specific questions you can ask here on this thread
or PM me

Re: Koffee Kosmo Roaster

Do a search on KKTO beta testers, all you need to know is in there.
I have one and it is a fantastic unit, i always get a consistent roast.

I used to use a corretto and thought that it was pretty consistent but the KKTO blows it away in the ability to consistently repeat the same quality of roast time and time again.

If your in SE melb suburbs then PM me and i can arrange a demo of the way i roast.

Either way just jump in and buy one, you wont be disappointed at all.

Re: Koffee Kosmo Roaster

Thanks Ill do a search for it. Also thanks thanks for the offer Mal Im in Sydney. Its good to have feed back from some whos used both.

Re: Koffee Kosmo Roaster

I have both and I can get a better roast more consistently from a KKTO than a corretto. The downside of the KKTO is the longer roast times and the inability to hear first and second crack (for me, anyway). I have learned to work around those limitations.

There are lots of beans in my stash that come out beautifully in the KKTO but found it quite hard to get a good result on the corretto. These are generally the softer beans which require a gentle heat. The Aussie MTC bean is a good example.

The KKTO is a much cleaner roast method. I can roast indoors near a window with a fan blowing the smoke out and not have to worry about chaff blowing around but I have to spend about a minute using the fan to blow residual chaff out of the roast.

I have had one roast with tipping on the KKTO which arose from experimenting with a raised floor to reduce the volume (and lower roast time). Tipping was  a problem for me on the corretto. The bean agitator on the KKTO is much better designed to move the beans about. The gentler heat means also that there is not too much heat applied at the wrong time.

Interesting...

My roast times are great and never have any problems hearing first or second crack..

Did 750G of PNG with BrewMan and pulled at a rolling second crack and bagged and sealed within 25min from First turning it on..

We were looking at the drip tray on teh Shuttle and it was teh Sounds of First crack breaking out across the rear deck that got our attention back to roasting.

Have heard others comment as to how quite FC and SC is, but with my system... Even second crack is as loud as FC in a HT......

Never have a problem at all... Maybe its just the type of mixing motor and paddle...

Re: Koffee Kosmo Roaster

AM, I too have no issue hearing 1st or 2nd crack
Roast times for me are about 16 - 17 min plus 5 mins of preheat of the beans to bring the whole system up to a starting temp of around 80deg

This I think is one of the factors that helps consistency regardless of bean type.

Re: Koffee Kosmo Roaster

I will pause briefly to point out the following:

AM - your roaster is not a KKTO, but a roaster based on KKs design with various modifications.

Mal - your roast time is 22 mins, which is about what mine takes.

Good points Steve. From what Ive read it seems most KKTOs are MKKTOs (M=Modified).

22mins is fine if thats what you set out to achieve, but a bit on the slow side if thats the best it can do....

I think roast time may depend on the TO type / element,  and insulation.   My setup is a bit of a hybrid (baccarat pots the same dimension as the arcosteel set), but has the same Tiffany TO & other parts as the KKTO.  When I first started I mistakenly did a few roasts in only about 14mins, but now purposely slow down the temp ramp, so 1C is about the 15min mark, and 2C 4-6mins after that.  

Slow roasts give much nicer, more even results with no tipping and no little black spots all over your beans....  

Re chaff:  Above the bean fill level, I cut out 1 inch high slits, every 1.5 inches, right around the inner pot, using a dremel.   I never have any chaff left with the beans; the circulating air works very well to get rid of the chaff.

Re noise: I cut out 3 layers of felt, and put that between the base and the pots.  It cut down the noise significantly.    I still have trouble sometimes hearing 1st and 2nd crack ,  with some bean types.   My hearing is not what it used to be though, from too many years of aircraft noise.

Prom previous roasts with a temp probe & DMM, looking at the graph with a template, I know at what temps 1C & 2C should occur anyway, and you can also pick it by the amount of smoke burning your eyes as you look inside to check the colour of the beans.

Only difference is the  mixing paddle and that I use a electric car window motor..

So yep I guess it is of Significant difference (major changes to outcome) that it can not be included in any general KKTO comparative discussion / feedback...

Now as all correttos are exact copies and all components are 100% the same; then I guess you guys would approve / OK  comparative discussion / feedback between correttos..... But a few slight differences between KKTO mean they can not be compared...


FFS How about some reality checks  

Every roaster is different but the methodology is the primary contributor to the out come... Not if the user is left handed or from Qld....

Re: Koffee Kosmo Roaster

Just for the record
I helped AM with technical advice and some materials to make his KK roaster well before the kit was thought of

Everything is almost the same exept for
1] motor 2] the agitator which is a bent wire 3] external insulation (no insert)

Took him a few months to get it together
Thats when I thought   there has to be a better way

AND

Since then I have had good quality home roasted beans in a Quantity that is suited to my throughput


I will have to get around and hear one of teh kits; as it just gets me that one might not hear FC ??? I could understand SC for some beans but FC is just so unmistakable for my system... Need to see / hear with my own two eyes/ears.

Re: Koffee Kosmo Roaster

I was under the impression AM is using a different turbo oven brand(Cookwell) and Im sure I read in one post that you had modified the shielding plate to make the holes bigger.

Your sarcastic comments dont help here AM. But before this becomes another "lets defend the KKTO" thread, go back and read my post and note the good things I wrote. My post was for chrisjohns info.
