SO, LET US BREAK THIS DOWN
Designed to Disrupt, or Sheer Brilliance.
Starting with a Vision to combine the Art of Coffee Roasting with the Science
that makes it work, the Sophistication in creating an Exceptional Quality in the
product it produces, but at the same time a Simplicity in it’s Application that
anyone can do it, this became, Our Mission.
Disrupters, you could say, taking on tradition and turning it on its head, converting Conduction into Convection and harnessing the magic power, that
Air-Motion Roasters possess.
It takes courage to take on tradition, but we were up for it,
and it worked.
Air-Motion Roasters, it’s all in the Design !
THE MAGIC IS IN THE DESIGN

THE ROAST CHAMBER
Things Are Heating Up
The Roast Chamber features a
precision-designed, cone-shaped stainless
steel tube with a perforated base.
Hot air enters at the base, lifting the coffee
beans in a vortex motion as it rises through
the chamber.
As the air dissipates after passing through
the beans, they cascade down the chamber
walls, recycling back to the lifting point.
This process provides full control over the
roast’s conduction, convection, and radiative
heat transfer. Managed by a temperature
controller and thermocouples within the
chamber, it ensures the even roast every
roaster desires.
CYCLONE EXTRACTION SYSTEM
It Sucks
Dust, moisture, chaff, and smoky air, produced during roasting are immediately extracted and diluted with excess air,
then is passed into the powerful cyclone extraction system.
The solids are efficiently separated and collected in a removable container, which can be emptied as needed.
The cyclone fan then discharges the
cooled, treated air into the atmosphere.
Additionally, the cyclone fans cool the roasted beans in the cooling tray,
efficiently bringing them down to temperature in just a few minutes.

The Cooling Tray
Too Cool
After water dousing stalls the roast and initiates cooling, the roasted coffee beans
are dumped into the Cooling Tray.
Agitator arms churn the beans while cool
air is drawn through them via the Cyclone System, reducing the bean temperature
in just a few minutes.
This rapid cooling process preserves the beans' flavour profile and prevents over-roasting, ensuring consistent quality in
every batch.
The controlled cooling helps lock in the coffee's natural aromas and enhances
the overall freshness, delivering a
superior product to the end consumer.
Better For Our Planet

The Challenge
Traditional coffee roasting processes are known to produce air pollutants, mainly particulate matter, combustion gases and volatile organic compounds (VOC’s).
Particulate matter emissions stem from the chaff (removed from the bean when roasting) together with condensation by-products.
Combustion gas emissions mainly stem from combustion of hydrocarbon-rich fuel for heat generation.
VOC emissions mainly stem from volatilisation of natural components in the beans and the reactions in the bean when roasting, as well as fuel burning.
With this in mind, it became the Mission of Air-Motion Roasters not to merely improve on traditional methods, but it became imperative to develop a technology (Air-Roasting Technology) that was not only more superior, but moving in the direction that was also
Better For Our Planet.
Our Key Consideration
We had to develop an over-engineered extraction fan and cyclone system
which would continuously remove chaff during the roasting process and then separating it from the gas stream before exhausting into the atmosphere.
We had to make the AMR Roaster all-electric instead of the conventional combustion of hydrocarbon-rich fuel for its heat generation.
We also developed an Open Chamber Roaster™ or (OCR), creating a gapbetween the roast chamber and the extraction hood, allowing ambient air to dilute and cool down the exiting heated air and gases from the roast chamber prior to being exhausted into the atmosphere.
We installed solar panels and an inverter system in our factory and canproudly say that we are totally off the grid and fully independent with electricity supply.
We are proud of our achievements so far and continue to work on our mission to make our roasters Better For Our Planet.
