Coffee Roasting!

There is NOTHING like the flavor of fresh roasted coffee filling the MTG-Technologies LLC Laboratory! Since 2013 we have been developing a fluidized bed bean roaster with electric heat and bean levitation control.

Starting in January 2016 we invested in an Ambex YM-2 roaster and am instrumenting and automating it. This work has been a labor of love. As pieces parts develop we will keep you updated. As for now the first level design is complete and the circuit boards are in production. All mechanical modifications have been made.

This year should be a great year for single origin COFFEE!


We finished our Roaster Control Software for Elkabodi Coffee LLC right around Thanksgiving 2016.

This control software uses multiple PID algorithms to control warmup, pre-roast, and roast temperatures.

All functions are automated, from bean drop, through cooling. It is a sight to behold!

It is customized for Elkabodi Coffee LLC's Ambex YM-2 Roaster.

Here is the Elkabodi Coffee LLC Ambex YM-2 after a few of the motors were taken off to make it lighter.

It is headed for installation at the Elkabodi Coffee LLC Roasting Facility.

Here is our control system modifications for the Ambex YM-2. We added a Maxitrol Gas modulation valve and an electronics bay to the right.

With the software finished, it's time to finish the automated control system and circuit boards.
