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 designed to ensure that each phase of the roasting process is precisely controlled for consistency and quality.

1. Drying Phase – Coffee beans begin with a high moisture content. We roast with air at five times the speed and volume of any other machine on the market. The hot air follows a unique path that can't be found anywhere else. It enters from the back and is directed to the bottom of the drum, which is fixed and perforated. In an upward and vertical course, it runs through the coffee beans along the entire length of the drum and exits through the exhaust pipe. This controlled high-speed, high-volume hot air circulation delivers unmatched consistency and efficiency compared to other roasting systems, delivering unmatched consistency and efficiency compared to other roasting systems, ensuring efficient drying and preparation for even development.
2. Browning Phase – As roasting continues, the Maillard reaction occurs, developing the beans’ colour and complex flavour notes. Unlike competitors, IRM Roasters do not use air recirculation, ensuring a cleaner, smoke-free flavour.
3. First Crack – When internal pressure causes the beans to expand and crack, they reach a light roast stage. IRM’s precise vertical airflow system directs hot air from the back, through a perforated drum, vertically through the coffee beans, and out through the exhaust, ensuring uniform roasting and a cleaner flavour profile.
4. Development & Caramelisation – This stage determines the final flavour profile. IRM Roasters provide advanced control, allowing roasters to fine-tune profiles and repeat desired results batch after batch.
5. Cooling & Final Processing – Efficient cooling is critical to locking in flavour. IRM’s non-recirculating air system guarantees rapid and controlled cooling, eliminating any risk of smoky residues and ensuring a clean, high-quality roast every time.

Unlike competing roasters, IRM Roasters do not use air recirculation at any stage of the roasting process. This is a crucial distinction, as air recirculation in other machines can leave smoky elements in the coffee, negatively affecting taste. The IRM system ensures hot air enters from the back, moves through a perforated drum, flows vertically through the coffee beans, and exits through the exhaust pipe, guaranteeing a cleaner, more refined cup profile.
