Brew-It Group is proud to distribute IRM Coffee Roasters to the UK and Ireland, offering cutting-edge air roasting technology that redefines precision, efficiency, and consistency in coffee roasting. IRM has built a reputation for combining decades of expertise with modern engineering, delivering roasters that prioritise sustainability, innovation, and ease of use.

The Coffee Roasting Process with IRM Roasters

Roasting is the crucial step in transforming green coffee beans into the rich, aromatic coffee that baristas and coffee lovers depend on. IRM Roasters are engineered to ensure every stage of the roasting process is precisely controlled for consistency and quality.

Key stages include:

Drying Phase – Coffee beans begin with a high moisture content. IRM roasts using hot air at five times the speed and volume of conventional machines. Air enters from the back, travels through a fixed perforated drum, flows vertically through the beans, and exits via the exhaust, delivering unmatched consistency and efficiency during drying.
Browning Phase – As roasting progresses, the Maillard reaction develops colour and complex flavour notes. Unlike competitors, IRM Roasters do not use air recirculation, ensuring a cleaner, smoke-free flavour.
First Crack – Internal pressure causes the beans to expand and crack, marking a light roast stage. IRM’s precise vertical airflow ensures even heat distribution and a uniform, clean roast profile.
Development & Caramelisation – This critical stage defines the final flavour. IRM Roasters give roasters advanced control to fine-tune profiles and repeat exact results batch after batch.
Cooling & Final Processing – Rapid, controlled cooling locks in flavour. IRM’s non-recirculating air system eliminates smoky residues and guarantees a clean, high-quality roast every time.

Unlike competing roasters, IRM Roasters never use air recirculation at any stage. Hot air enters from the back, moves through a perforated drum, flows vertically through the coffee beans, and exits through the exhaust pipe, ensuring a cleaner, more refined cup profile with exceptional consistency.

Why Choose an IRM Roaster?

The IRM Roaster range is built to offer a seamless roasting experience, providing advanced air roasting technology that guarantees an even roast across every batch. Here’s what sets IRM Roasters apart:

Unique Air Roasting Technology

Unlike traditional drum roasters, IRM machines use high-speed, high-volume hot air circulation from the base, evenly roasting each bean while preventing smoky residues.

Sustainable and Energy-Efficient Design

IRM is committed to reducing energy consumption and emissions, making their roasters an eco-friendly choice for modern businesses.

Low Maintenance Stainless Steel Construction
