The next generation of drum batch roasters

The Ghibli R30 Commercial Coffee Roaster is an advanced roasting machine that allows perfect control over the roasting process, in order to meet the desired results and cup profiles. The Ghibli R30 enables roast masters to pre-define their desired calibration preferences.


Ghibli R30 is a heavy-duty machine with robust features under the hood. It offers a fully closed fairing protected by its insulated and covered-drum housing. The Ghilbli R30 comes complete with smart-thermal sensors and noise-reduction components.

New generation installation choices

The ergonomic design is ambidextrous for both right and left-hand users. This left/right selection option enables users to install and position Ghibli R30 in any desired location, regardless of the existing infrastructure on site.

Clean, Green, & Safe

The Ghibli R30 is designed to achieve the highest roasting efficiency, to minimize pollution, and reduce gas consumption. Cellar-Tech’s research in thermodynamics, airflow routing, precision gas burners, and high-efficiency combustion chambers, to reality.


Making a huge step forward in quality roasting, the Ghibli R30 delivers superb results, free from defects, even with the most stubborn beans. It shows a wonderful smooth ride over the entire batch and is also suited for rapid roasting batches. It is also perfectly suited to roast smaller quantities, less than a full batch.

Precision Design

To deliver unmatched power and precision, the Ghibli R30 is based on advanced product design software, extensive lab research, and rigorous testing methodologies. The result is a meticulously designed roaster, which optimizes the entire scope of elements that produce a superior roasting process.

Advanced set of features:

  • Advanced thermodynamic characterization.
  • Smart Vortex drum, allowing 90% less air to alter the heating characteristics.
  • Fully modulated burner, providing precise control with 100% burner power resolution.
  • Option for two gas burners.
  • Dual positioning option for the burner relative to the drum.
  • Precision drum housing, to ensure the drum always spins “in line”, with a sturdy design.
  • In-drum fluidizing paddles, designed to perfectly stir the beans.
  • A high capacity, high pressure cooling blower provides a substantially shorter batch cooling time.
  • LED-illuminated magnifying glass, for better trier sample viewing
  • Enhanced visibility with three tempered glass lenses encircling the roaster. These lenses provide easy viewing into the combustion chamber, green hopper window, and into the drum to view your beans while roasting.
  • A collection bucket is supplied for the roasted beans, made by food-grade stainless steel, wheeled, and elegantly styled to complement this lavishly designed machine. Replacing any unfitted plastic containers that function as elaborate collectors.

Perfect Heat Dispersion

As part of the entire Ghibli line, the R30 is designed with a closed ceramic combustion chamber surrounding the drum, ensuring heat distribution remains uniform at all times. Secondary air is allowed to enter by measure, and only through specific ducts positioned at the most crucial points. The heat is exchanged with the cold air on its way to the drum, with maximized efficiency.

Clean, Green, Safe, and Efficient Heating System

The new Vortex drum design dramatically reduces the required intake of the secondary cold air flow. This directly impacts the amount of gas for burning, so that much less is needed to keep the process at optimized temperature ranges. Less gas means lower running cost, fewer impurities and polluting fumes, and minimized energy for smoke treatment with less air and less combustion. Coffee-Tech’s entire Ghibli line features a highly efficient pre-mix, low NOx gas burner. The Ghibli R30 roaster comes equipped with one or two fully modulated burners. It provides a wide range of settings that easily maintain a constant heat. The roaster’s clean heat source provides maximum gas-burning efficiency, with minimum levels of carbon monoxide emissions. Safe for the operator, roastery employees, and the coffee itself. The Ghibli R30 is highly cost effective and stable, featuring many parameters for control and calibration as described in detail in our user manual. Each machine is tested and calibrated using a combustion gas analyzer, for optimal calibration.

User and Ambient Safety

Coffee-Tech Engineering’s entire Ghibli line is constructed with a closed-sealed ceramic combustion chamber. The combustion chamber is the drum housing itself, which is under negative pressure throughout the roasting process. Sucking the secondary air through specific ducts, it is the only place into which air can penetrate. Our advanced design ensures the roaster’s surrounding is kept completely pollutant free, with zero gas or odor discharged to the immediate environment. Coffee-Tech Engineering machines are designed for a superior roasting experience, with a superior coffee flavor, while ensuring top safety measures.


  • Coffee-Tech Engineering roasters, the Ghibli R30 among them, are featured with an in-drum fire extinguishing faucet that is connected to a live water line.
  • The R30 is equipped with a manual drum evacuation crank. In the case of a fire, users can perform the procedure single-handedly, as the drum door automatically remains open based on our safety design and advanced mechanisms.
  • The outer stainless-steel wall is shielded by the machines fairing, to ensure no heat is reflected back onto the user or into their surroundings.

Feature-Rich Offering

  • Drum door is smoothly operated on oil-free bearings and has an intricate deadlock closing mechanism instead of those nasty metal weights.
  • Drum gap is easily set by a micrometric regulation hub, even while the machine is in mid-cycle.
  • The roaster’s main self-aligning bearing hub is sealed, to avoid grease leaking onto the cooling pan.
  • The roaster has a smart drum opening and paddle geometry for fast drum evacuation.

Roast Profile

Ghibli R30 is equipped with a touchscreen panel and built-in roasting profiler, exclusively developed by Coffee-Tech Engineering. Users can pre-set and control the roasting process, for either manual or automated mode. It can also integrate into roast data logging applications and software, using an external USB cable. This Profiler enables any user to pre-define and program their personal roast profiles. By recording the desired heating curves, any roast profile can be applied time and again, with pinpoint accuracy.

  • Ergonomically designed for simple operation and easy maintenance. The control panel features an emergency stop switch, a USB port for computer connection, and an accessory operating platform that includes optional features such as de-stoner and pneumatic loader with individual frequency inverters. Any other optional feature can be added, hassle-free.
  • The profiler analyzes the internal temperature at three distinct locations, simultaneously managing the fully modulating burner. In addition, the software also controls the drum speed and airflow within the drum, allowing complete control over the entire process.

Robust Yet Simple Chaff Evacuation System (Optional)

Ghibli R30 can come with an automatic, heavy-duty chaff evacuation system. It continuously empties the chaff into an external bucket, and is designed to ensure no accumulation falls inside the cyclone. During operation, all that remains is to simply dump the contents of the bucket, at any time. To clear the chaff, there is no need to stop the machine or rush over to it especially at any point during your roast, since the chaff has already exited the machine.

Chaff Compacting Device (Optional)

For the Ghibli line, a compacting device can be ordered to complete the chaff evacuation system. It packs the chaff into small capsules that can be put away for later reuse in heating or for agricultural purposes.

Cooling Group

The Ghibli R30 is equipped with a stainless-steel cooling group, which has a large stainless steel screen mesh that remains clean and residue-free for life.

Here are some of its benefits

No cleaning is required, as it operates with a Teflon agitation blade and a dedicated high-capacity cooling blower. The cooling group also features two cleaning doors for easy access.

Next-Generation Vortex Roasting Drum

The Ghibli R30 blasts an airstream in spiral motion into the drum and through the coffee bean mass, requiring a smaller amount of air to enter the roaster for a full effect. The longer spiral path across the drum and through the coffee bed is unlike the olden traditional roaster mechanisms, which had a perforated back plate allowing huge amounts of air into the drum in a short, straight path. With our Ghibli line, the beans are not stripped from their natural coffee aromas or taste. The energy of the airflow is also used to maintain the heat next to the exhaust. This innovative approach ensures a unique added value for cost-effectiveness, energy optimization, and enhanced flavor. Lab tests have already shown a huge improvement in the coffee’s solids content and density, with amazing improvements in gas consumption, roasting time, and fume emissions.

Everything at Coffee-Tech is designed using 3D CAD; this enables us to be very precise with each and every aspect of the machine. Coffee-Tech Engineering takes pride in producing high-tech, efficient, and compact machines. Every single piece of our machines have a professional significance; we leave nothing to chance.

An Afterburner is a system used to eliminate (burn) smoke and odor coming from the coffee roasters’ exhaust system.

There is no definite answer to this question; this depends on where you are roasting and what your surroundings are. If, for example, you are roasting in a residential area, most probably you will need an afterburner (or the Avirnaki system if you are using a shop roaster). The need for an afterburner depends on many factors that vary from one country to another and sometimes even from one city to another – neighbors, local regulations, licensing etc. The best thing to do is inquire with your local authorities regarding your roasting facility plans.

During the processing of coffee, in producing countries, various foreign materials find their way into the green coffee bags – stones, metal objects, glass and more. These objects, if not removed, can bring serious harm to equipment such as grinders. A De-Stoner is the machine that pneumatically removes these foreign objects from the roasted coffee and drops them into a sieve. Our De-Stoner also comes with a frequency inverter that allows the user to adjust the airflow according to the coffee variety or roast degree.

The most preferable configuration is a straight-up duct (chimney), through the roof and free to the atmosphere. Side ducting is also possible but, if used, should follow some fundamental principles – contact us for further advice. The best material for ducting is double-walled stainless steel.

James credits a pour-over in a Pacific Northwest coffee shop with opening his eyes to the world of fine coffee – and to a new and different style – bright, acidic & fruity coffee.

He had been enjoying brewing coffee in everything from a French Press, AeroPress and Moka-pot, but this pour-over experience was an awakening, and things haven’t been the same for him since the first sip of that pour-over.

When asked what his go-to coffee is these days, his answer is - It depends...... He’s partial to pour-overs, especially in the warmer months where the bright, fresh characteristics can shine through. He also loves espresso - describing it as a magnifying glass for flavours.

James has been an amateur coffee roaster for over 2 years and has completed his Level 1 Certification in Coffee Roasting. He spends a lot of time at Red Bird Roasting, working on perfecting his roasting game!

With his first “A-HA” moment fueled by an order of “traditional cappuccino” at The Bean Scene in 1998, and armed with a Fresh Roast SR300 coffee roaster and a Saeco Estro Vapore espresso maker, Peter has been conducting smokey coffee-roasting experiments at home for over 25 years.

He prefers bolder flavoured coffee with unique flavours that can still stand out when a bit of steamed milk is added to the mix. He typically makes an espresso in the morning using test roasts from Red Bird Roasting. His go-to at work is an espresso from a Pavoni manual lever-style machine mixed with a bit of hot water to make a strong Americano.

Pete loves sharing his passion with his family each Christmas by roasting them a custom bag of coffee that he feels most closely resembles their personality and including those tasting notes overlayed on an old family photo of them for the label.

Powell remembers getting up early to go to work with his Dad, and on the first day, they arrived to work a half-hour early. He was surprised to find a break room full of his dad’s colleagues who had arrived at work well before opening in order to enjoy a cup of coffee, converse and connect as a team. As Powell recalls, “It was a culture I had never seen before. I poured a coffee and blended into the group. The coffee looking back was not the best, but the first experience is engrained in my mind.”

Since then, Powell’s love of coffee has been fostered throughout his travels. His first “A-HA” moment with coffee was when he had an authentic cappuccino for the first time at a small café in Italy. He describes the rich, creamy espresso paired with frothy milk as a “revelation” – perfectly balanced flavour and textures. From that moment on, he was hooked on fine coffee and began exploring brewing methods and coffee profiles.

Powell is an experienced engineering & sales professional with a background in various mechanical equipment & working with customers on equipment solutions. With over a decade of experience in the beverage industry, he’s ready to put his experience to work for you!
