Once coffee is ground, the degassing process becomes critical: CO₂ release is rapid, oxygen sensitivity increases, and aroma compounds are at risk. Without proper management, packaging can inflate, oxidation can degrade flavor, and shelf life is shortened. IMF offers advanced degassing systems for ground coffee that accelerate stabilization while ensuring maximum aroma retention and production efficiency.
Ground coffee rests in dedicated degassing hoppers under nitrogen blanketing. This reduces oxygen exposure and allows CO₂ to escape gradually before packaging.
Using vacuum pulses combined with nitrogen backfill, IMF systems significantly shorten degassing times—ideal for high-volume plants and single-serve production.
Depending on grind size, roasting profile, and production requirements, IMF systems can reduce degassing times from 24–48 hours down to just a few hours, while preserving cup quality.
Oxygen kept at ultra-low levels to prevent oxidation and preserve volatile compounds.
Accelerated degassing reduces holding times, boosting plant productivity.
PLC/HMI with programmable cycles, trend charts (O₂/pressure/temperature), alarms, and data logging; SCADA/ERP connectivity available.
Designed for grinding lines, single-serve capsule/pod fillers, vacuum packers, and brick-pack lines.
Hygienic construction, food-grade contact parts, and interlocked access panels.
IMF’s Natural Degassing hoppers allow ground coffee to stabilize under controlled nitrogen blanketing.
This prevents oxidation, protects aroma, and ensures CO₂ release before packaging. Ideal for medium-capacity lines where extended shelf life is essential.
Vacuum + Nitrogen Injection
IMF’s Accelerated Degassing systems use vacuum pulses combined with nitrogen injection to drastically reduce degassing time for ground coffee. Designed for high-output roasting plants, these systems enable packaging within hours instead of days—without sacrificing quality.
IMF combines decades of roasting expertise with process automation and after-sales support to provide degassing systems that deliver speed, consistency, and quality. Our engineers configure each solution to your grind profile, packaging format, and throughput requirements.
Contact IMF Roasters to design a ground coffee degassing system that accelerates readiness, reduces waste, and guarantees maximum preservation of the coffee aroma.
IMF integrates dense-phase conveying technology to transport roasted coffee in slow-moving plugs of beans through sealed pipelines.
Ensure homogeneous mixing of ground coffee while integrating precise micro-dosing of flavours and spices.
Our portfolio covers roller and blade/impact technologies, sized from pilot plants to multi-ton-per-hour production.
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.
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.
The IMF’s higher air throughput offers superior control of roast curves at all times, especially when most needed late in a roast.
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.
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.
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.
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.
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.
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.
Our sales or technical team will get in touch as soon as possible.
