1. Why Roast with NIR Radiation?
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.
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.

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

What Our Users Say
I have tried some traditional roasters, but with the Rubasse, I discovered unexplored flavor notes in my Indian coffee beans that I have never found with other roasters. It’s quite surprising how the Rubasse can reveal new notes & aromas.
JC Mysore, Green coffee exporter & coffee roasters, India
The roaster is very responsive with a high level of control allowing you to easily roast your coffee in the way you want, then after you have created your ideal profile you are able to replicate the roast knowing that it will keep repeating your roast with a high level of consistency.
