Very little information available for this unit, going to show my progress. Hopefully it will help some one.
Coffee Tech Torrefattore
Made in Israel
Capacity 1kg
Electric roaster
Perforated drum
Made in 2004
First unit in the imported to the USA #001
Great roaster, well build, and roast very well.
Had been working today on cleaning it, calibrating the large dial temp gauge, and figuring how to install the Fuji PID controller. Unit was upgrade in the past to have Omega controller, so this should make it simpler.

Took heating element cover off, it have 3 heating element 500 watts each, all of them are wired to one power switch.
The new version of this unit, have two heating element wired to one switch, and 3rd heating element wire to 2nd switch.
As I am going to connect it to PID controller, I probably will be better to connect the 3 to it.
Gotten huge spare part box, 8 heating elements, 2 motors, 3 barring, one gear box, and bunch of switches.
This is the first unit sent to the USA. Serial number is #001

Unit come with this thermocouple, any one know why it have two electric connection?
I google it and could not find any info.

Thanks for posting roaster porn!
If I had to venture a guess (its all I gots), I'd say the probe is multi-point, and has two separate measuring positions. Trial and error will confirm. Cheers!

It's a split wire thermocouple, one lead for the roaster and the other you can hook up to a computer running Artisan. Or possible a display lead and controller lead?

Cool, very useful.
Well unit have some issues, seems like heating element are wornout I was not able to reach above 370 degrees F
The omega control is about 100 degree off, so maybe this is what cause the problem... But as I am going to switch to PID controller, it is no big deal.

I wish my roaster was an electric unit just based off the simplicity of running a pid. I think you will like the Fuji PID. They are better integrated into Artisan compared to the others.

Have you seen this:
seems like a simple and inexpensive gas PID control
I actually greatly prefer gas, but gotten this unit for great price, and there is a lot of love toward this MFG at the Australian coffee news group

today I adjusted/ calibrated the OMEGA controller, much easier to roast now.
I discovered that drum is rotating in the wrong direction... I guess when they installed the new motor they installed the gear box in reveres.
so tomorrow will change barring, and install the brand new gear box that come with it

Changed bearing old one were dead(http://tapatalk.imageshack.com/v2/15/01/24/f31e5186853e0328b26e365751edbccc.jpg)

Changed gear box, and discovered that the wrong drum rotation was due to motor wiring (pic show wrong rotation)(http://tapatalk.imageshack.com/v2/15/01/24/a9b8d96eb4481e931087a400cc44c5d1.jpg)

One problem, that one of the insulated ring between frame and barring is (http://tapatalk.imageshack.com/v2/15/01/24/0934fbdf976ef4f1b1359367c6b6bd90.jpg)broken. Seems like Asbestos. Need to find replacement.

Machine is rated at 1kg, today to test it, I done 3 roast of 2lb. Way over machine real capacity.

PID is installed
