Direct Roasting

Using radiation to roast coffee saves you time, energy, and worries about underdeveloping your coffees.

Directly applying penetrative radiant energy onto the beans, radiant heat develops the coffee quicker & more evenly comparing to traditional (convective + conductive) roasting.

 

Radiation ≫ Convection

Radiant heat is evenly absorbed by the total mass of a coffee bean.

Convective heat (hot air) is mainly & firstly absorbed by the outer surface of a coffee bean.  The heat needs time to penetrate deeper.


Roasting with radiation means:

● Faster roast development (especially as the beans get darker)
● Less uneven and/or prolonged "baked" roasts.

 

Powerful Roasting

Gone are the days of slow and sluggish electric coffee roasters.

Near Infrared Radiation (NIR) roasting machines can achieve roasting durations similar to (or faster than) gas-burning roasters while only needing less than half of the total energy consumption.

 

>50% Roast Energy Savings

Switching the primary roasting energy source from hot air to radiation benefits roasters with tremendous energy savings.

Our center-placed radiation power element ensured maximum radiant heat utilization, resulting in the world's most energy efficient roasting process (proven by the 3rd party research in the Appendix section below).

 

Cool & Comfortable Roasting Environment

Improving roast energy efficiency by roasting with radiation also means less waste heat being released in to the roasting environment.

The benefits: 

● Comfortable, cool roasting sessions
● Way less money spent on air conditioning

 

Auto Preheat

The Auto-Pilot system automatically idles the bean temperature at your charge temperature.

Power output and airflow setting are controlled by the system to ensure stable initial energy at the start of the roast.

 

Auto Roasting
Rubasse Back-tracking Algorithm

Specialized algorithm takes full control over radiation heat & airflow settings, corrects temperature deviations swiftly, and replicates your unique profile with precision both on the graph & in the cup.

 

Auto Roasting
Differential Pressure Profiling

Rubasse's "Pressure Compensation" feature mitigates possible effects on the roast caused by air pressure issues such as clogged ducts over time or weather/ambient changes...etc. 

 

Full Knowledge of Your Roasts

Fully digitalized roast control & roast data sensors enable users to roast with precision & insight.


Roast data includes :

Bean temperature
Bean temperature rate of rise (RoR)
Exhaust air temperature
Drum surface temperature
Differential pressure
Exhaust Moisture*

 

Meticulous in Data Consistency

Low quality data sometimes is worse than no data.

To obtain truly informative insights, we make sure that our roast data collection is flawless from an engineering perspective - starting from making & hand-tuning each & every temperature sensing probe!

 

1st Crack Navigator

● More reliable way to mark 1st crack
● Perfect post-crack heat application
● Avoid the "Crash & Flick" with ease

The above are some of the highlighted benefits roasters gain after including our exhaust moisture data into their roastings. 
 

Visualize How Coffees "Roasts Differently"

You can now see possible reasons behind common sayings such as "Kenyan coffees like to crash" or "Naturals tend to fly-off near the end of roasting"...etc.

The exhaust moisture curve gives you previously inaccessible, crucial information when designing roasting heat profiles for individual coffees.
