When multiple origins and roast profiles converge, homogeneous blending is essential to ensure consistent flavor, extraction, and packaging performance. IMF designs roasted coffee blending systems that protect bean integrity, integrate precise batch weighing, and connect seamlessly with storage silos, grinders, and packaging lines—delivering repeatable quality across every batch.
High-precision weighing before/after blending to verify shrinkage, achieve target ratios, and control inventory.
Reduced drop heights, smooth transitions, and controlled velocities to preserve whole-bean structure.
Automated feeders for solids; liquid dosing skids with spray or atomizing nozzles for coatings; recipe-driven for consistency.
Route blended beans directly to packaging lines or to grinders for ground coffee formats.
Enclosed housings with aspiration take-offs routed to the plant’s central filtering system.
PLC/HMI with recipe management, lot tracking, audit logs, and optional link to IMF Production Manager® and SCADA/ERP.
Food-grade contact surfaces, smooth finishes, and quick access for sanitation and flavor changeovers.
Magnets/metal detection, inline sampling, LIW or batch dosing downstream, oxygen/CO₂ vent management to protect aroma.
Energy-optimized drives, predictive maintenance prompts, and easy-service layouts to minimize downtime.


The IMF Horizontal Drum Mixer is designed for homogeneous blending of roasted coffee beans with the highest care for bean integrity. Inside a rotating drum, bidirectional helical flights gently circulate beans back and forth, achieving fast and uniform mixing with minimal breakage and fines.
With capacities up to 2.5 tons per hour and the option for continuous feeding during blending, this solution is ideal for large-scale roasteries requiring consistency, reliability, and gentle handling.
IMF Flavouring Blending Systems allow roasters to create value-added flavoured coffees by combining roasted beans with solid granules (such as cardamom, spices) or liquid flavourings.
Engineered for gentle handling, these systems ensure uniform coating or distribution without compromising bean integrity or aroma.

Every conveying line is tailored around your coffee type, throughput, and layout.
Engineered to minimize drop impact, control dust, and prevent breakage—so aroma, structure, and cup quality are preserved all the way to packaging.
We spent months researching, testing, and tasting before finally bringing home our first IMF air roaster. The results were a revelation. This machine unlocked a new dimension of clarity and sweetness in our coffees like Raxidi Lobo Estate, Ratnagiri Estate YC01.
Blue Tokai Coffee Roasters - India
IMF – 60 kg (2020) This machine took me into professional roasting. A combined drum + hot-air system with energy-efficient heating, afterburner, filter, and a destoner to remove any foreign particles. Because the system is closed and uses controlled hot air, it keeps the roast clean, even, and stable — no burnt spots, no uneven heat, no weather influence. Summer heat or winter cold doesn’t matter; the roast curve stays the same. Many typical roasting errors are eliminated by design. This is the level you need before going to the market with real volume — precision, repeatability, and protection against mistakes.
Dritan Alsela Coffee - Germany
The IMF’s higher air throughput offers superior control of roast curves at all times, especially when most needed late in a roast.
Prodigal Coffee - United States
Once we saw IMF's impressive operation, we were confident enough to cancel the rest of our manufacturer visits. Not long after, we placed an order for both our manual RM5 and an automatic RM60. The deciding factors were efficiency, roast quality and support.
Our RM60 provides a consistent, high quality roasting experience that supports our focus for delivering quality coffee to our café partners and home customers.
Tall Order Coffee Roasters - Ireland
With the goal of creating new solutions capable of ensuring ever-higher quality standards and cutting-edge technologies, we enthusiastically began sharing ideas and constantly discussing suitable solutions.
The goal is to guarantee consumers high-quality coffee. The coffee roasting process, for example, the result of the ongoing collaboration between the two companies, has now reached extremely high levels in terms of quality and process technology.
Caffè Borbone - Italy
I would highly recommend IMF to anyone looking for a quality machine, a roaster that allows consistent repetitive roasts, and a company that is always available to help when an issue does arise, which is not always the case in the manufacturing sector of the coffee industry.
Brûlerie des Monts - Canada
I would absolutely recommend to every roaster to consider IMF. IMF was the only machine that had no limitations when it comes to power or batch capacity. It is nice being able to roast a full batch in under 8 minutes. Being a full convection machine allows specialty roasters to roast few points lighter without risking underdevelopment.
Also, I believe every business today is trying to reduce their carbon footprint. Technology that comes with IMF requires no afterburner and consumes 30% less gas compared to other manufactures.
Bell Lane Coffee - Ireland
I knew IMF by a German dealer and found it’s concept very interesting.The most important things in IMF’s roasters are the integration of an afterburner in the roasting machine and the method of heat transfer by air. The first one leads to lower energy consumption and emissions compared to a roaster plus traditional afterburner.
JOCaffè Rösterei & Maschinen - Germany
and the ease in which we can adjust the process without chasing a roasting curve. I really like to create the roast profile based on hot air in instead of hot air out. Also the build in afterburner is a big advantage.
We were looking for a IMF 15kg model but we were offered a 30kg used model and chose that one. We are really satisfied with it.
