ROAST OUTSIDE
THE BOX

1. Air Technology

At IRM, we roast with air — at five times the speed and volume than traditional air roasting technologies.
What makes our system unique is not just the power of the air, but its precise and distinctive flow path.
The hot air enters from the back of the machine and is directed to the bottom of the drum, which is fixed and perforated.
Then, following a vertical and upward path, the air passes through the coffee beans along the entire length of the drum and exits cleanly through the exhaust pipe.
This creates uniform heat distribution and exceptional roasting control — a design that cannot be found anywhere else

2. Hybrid Drum Structure

Our drum is not a simple cylinder. Only its lower part is cylindrical, while the upper section is open, featuring a hybrid, polygonal geometry.
This design prevents beans from sticking to the walls or centrifuging, ensuring free movement and optimal development.
Inside, custom stirring flaps gently agitate the beans, allowing for even exposure and refined flavor extraction.

IRM coffee roasting machines are built for high performance — and built to last.
They are made entirely from premium stainless steel, and every component is individually designed with precision using SolidWorks 3D engineering (CUD Construction – Dassault).
Each machine is assembled by hand, with attention to detail, accuracy, and real craftsmanship.

IRM means more than performance.
It means durability — machines that can run continuously, 24 hours a day, without the downtime or inefficiencies of lengthy heating and cooling cycles.

Heat doesn’t wear them down. It doesn’t weaken them. Ignition is not a threat.

This is the kind of consistency you can rely on — Roast after roast. Year after year.

ECONOMY: At IRM, efficiency is not an afterthought — it's built into every decision, every detail, every roast.

From the direct introduction of air into the drum, to the use of top-tier industrial insulation, and our high-performance burner system, everything works together to reduce energy consumption and maximize output — achieving up to 50% savings in gas or electricity use compared to conventional machines.

Our roasting cycles are faster — a full roast profile in just 8 to 10 minutes, compared to the 15–17 minutes of traditional systems.

Heating up takes only 8 minutes (instead of 30 to 40), and cooling down just 8 more — compared to the 60 to 90 minutes required by conventional machines.

That’s more batches per hour, less waiting time, and up to 40% more productivity, without compromising quality.

But true economy isn’t only about speed.

It’s about doing more with less — less fuel, less energy, less waste.

It’s about delivering premium performance while reducing cost, so you can focus on your craft, your coffee, and your business.

At IRM, freedom means having the power to roast your way.
Our machines deliver the same efficiency, control, and flavor development across all kinds of coffee — from dark to light, from delicate single origins to bold espresso blends.
You’ll be pleasantly surprised to see that even lower-grade coffees can reach new potential when roasted on an IRM — just like the finest specialty beans.

And while the engineering is advanced, the experience is intuitive.
The machine is incredibly simple to use, even for beginners.
It responds instantly to the operator’s commands — typically within a second or two — creating a seamless connection between roaster and machine.

What truly sets IRM apart is freedom of control.
Every roasting parameter — burner, airflow, drum speed, and more — is 100% customizable, simultaneously and in real time.
Where most machines limit adjustments to only one or two variables, IRM gives you total control, without restriction.

Whether you're refining a high-end profile or experimenting with a new blend,
IRM gives you the freedom to explore, repeat, and perfect — exactly as you imagine it.

What makes IRM truly different is not just how it works —
but how it makes coffee taste.

The unique combination of advanced air technology and hybrid drum geometry gives our machines an undeniable advantage:
a taste unlike any other.

We’ve redefined the very path of the bean and reimagined the constants of traditional roasting.
With IRM, every bean is suspended in hot air, not pressed against metal.
It’s exposed to precisely the same temperature and time, ensuring even development and no charring.

The mixed, open geometry of the drum allows the beans room to move — and room to grow.
Unlike conventional cylinders, our design makes it possible to add more rotations without causing centrifugal pressure.
Roasting happens at 80 RPM instead of the typical 60 —
more movement, better control, deeper flavor.

And when the roast is complete, three powerful blowers instantly flood the drum with cool ambient air.
The coffee exits in just three seconds, and is fully cooled within 2.5 minutes.

This ultra-fast cooling process locks in the aroma, preserves the complexity, and protects every delicate flavor note.
The result?
A cup so vibrant, so full, it can’t be described — only experienced.

At IRM, sustainability is not a trend — it's a responsibility that guides every machine we build.
We believe true innovation must respect the planet, the people who work with our machines, and the coffee itself.

That’s why every IRM roaster is designed to reduce energy consumption, minimize emissions, and prevent waste — all without compromising performance.

Our air roasting system delivers up to 40% energy savings, thanks to faster cycles that avoid unnecessary fuel usage.
And because the airflow is non-recirculated, no smoke or residues ever return to the bean — preserving both flavor purity and environmental integrity.

Built entirely from premium stainless steel, IRM machines are engineered to last for decades — reducing waste from replacements and minimizing maintenance.
This is sustainability in its most tangible form: strong, clean, and future-minded.

But sustainability goes beyond materials and energy.
It also means creating safe, ergonomic workplaces.
IRM roasters are cool to the touch, ideal for small spaces, and easy to operate — helping to foster a healthier, more efficient daily workflow.

With IRM, every roast becomes an act of care — for the coffee, for the people, and for the planet.
Because the future of coffee deserves the same attention we give to its taste.

AUTOMATION

At IRM, automation is not just a feature — it’s a philosophy of precision, control, and intelligent roasting.

Every IRM machine is fully automated and built around an industrial-grade Mitsubishi PLC, ensuring seamless operation, real-time responsiveness, and unmatched reliability. But automation goes far beyond mechanics — it’s about turning data into action, and control into consistency.

That’s where Kai-Zen comes in. Kai-Zen is IRM’s proprietary digital platform, developed to connect roasters to their machines in entirely new ways. Inspired by the Japanese concept of continuous improvement (改善), Kai-Zen empowers roasters with real-time data, advanced analytics, and complete remote control — from any device, anywhere in the world.

And it doesn’t stop there. IRM machines are equipped with a full array of sensors and intelligent protection systems to ensure safe operation and optimal performance in every batch. These systems work silently in the background, protecting both the machine and the people who use it. 

But the real game-changer is our AI EDITION. These next-generation machines bring the roaster into the realm of artificial intelligence — a world of autonomous learning, adaptive roasting, and next-level consistency. With AI at the helm, automation becomes a powerful ally —helping you master the core challenge of roasting: perfect repeatability. 

From data-driven profiles to intelligent automation, IRM puts the power of precision and the freedom of technology in your hands. This is automation — the IRM way.
