The most complete coffee production system

The Ghibli R90 is not another average commercial drum roaster. Coffee-Tech’s loyalty to the endless pursuit of excellence ensures that our roaster produces a boutique-quality coffee with a full aromatic spectrum in commercial quantities, something hitherto unachieved by standard commercial configurations.

Precision Design

With the help of advanced design software, every attribute of the Ghibli R90’s construction was meticulously designed to optimize each part of the roasting process. Thanks to extensive research and painstaking attention to detail, the Ghibli R90 can offer:

• Advanced thermodynamic characterization.
• Precision drum housing, ensuring the drum always spins “in line”, with a sturdy design that will bear the load for many years.
• Exact proportion in drum design, achieving an optimal ratio of conductive and convective heat.
• In-drum fluidizing paddles designed to perfectly stir the beans, create greater heat conduction between metal and beans, separate chaff and immediately evacuate the beans from the drum into the cooling group.

Perfect Heat Dispersion

We have conducted intensive research on closed ceramic combustion chambers. The ceramic surrounding the Ghibli R90’s drum ensures that the distribution of heat is always equal; with cold air unable to penetrate the drum. This presents a marked improvement over the common setup of self-aspirated burners, where heat is applied directly to the drum at a single point.

Clean, Safe and Efficient Heating System

Coffee-Tech’s entire Ghibli line features a highly efficient turbo gas burner. This special roaster is equipped with a dual-stage modulated burner; providing a wide range of settings able to maintain a constant heat. This clean heat source provides maximum gas-burning efficiency with minimum levels of carbon monoxide emission. Safe, economical and stable, it features many parameters for control and calibration, all described in detail in our user manual.

Comprehensive Set of Features

Coffee-Tech pays special attention to the less obvious details, such as the compact, efficient structure of the roaster, batch cooling time, drum evacuation time, the size of the monitoring control lens and drum gate, the addition of a lens in the green bean hopper and more. At the end of the cycle, the entire roasted batch is transferred to the cooling group in a matter of seconds. These features are often ignored but their impact is tangible in the finished brew. Every setting and modification are tested in laboratory conditions to ensure the best cup of coffee possible.

[Optional] Roasting Software

Alongside the Ghibli R90, Coffee-Tech offers unique roasting software, PC operated, developed exclusively by Coffee-Tech Engineering, that completely automates the roasting process. The software enables the user to predefine and program personal roast profiles. By recording the desired heating curves, an endless number of roast profiles can be applied time and again with pinpoint accuracy.

The software analyzes the internal temperature at three distinct points, simultaneously managing the two-stage modulating burner. In addition, the software also controls the drum speed and airflow within the drum, allowing for complete control over the entire process.

Pneumatic Elevator for Green Beans:

This machine is equipped with a floor-mounted green bean elevator for easy loading. It can be controlled by the roasting software or manually from the control panel.

Pneumatic doors actuation:

All doors on the Ghibli R90 feature pneumatic actuation, aided by air pistons and electro-valves and can be operated semi-automatically from the control panel or automatically by the software.

Control Panel

The Ghibli R90 is equipped with a self-standing control panel, ergonomically designed for operation and easy maintenance. The control panel features an emergency stop switch, indicating lamps for the burner and afterburner, a USB port for computer connection, individual switches for all electric and pneumatic functions of the machine, includes optional features such as a de-stoner with its individual frequency inverter, and with all other optional features mentioned.

All electrical control components and motor protections are installed in this unit. This allows for very easy maintenance and service without the need to open the machine itself. In the event of a failure, the control board can be shipped separately for repair or exchange.

Cyclone Chaff Collector

This machine comes with a heavy gauge, galvanized, painted steel chaff collector that can be taken apart with basic tools for cleaning. Cleaning is a tedious but necessary procedure on any commercial roaster, but we make it safe and easy to do.

(Optional) Chaff Compacting Device

With the Ghibli commercial line, you can order a compacting device for your cyclone. This will pack your chaff into small capsules you can simply throw away or reuse for heating or agricultural purposes.

Cooling Group

The Ghibli line is equipped with a stainless-steel cooling group, a big screen mesh that requires no cleaning, Teflon agitation blades, and a dedicated high-capacity cooling blower. The Cooling Group also features a big cleaning door and pneumatic evacuation opening – all covered for food safety and protection.

Volumax cooling system obtains homogeneous immediate cooling. It ducts a high volume of pressurised air all around the cooling pan through the perforated cooling pan wall, in addition to the main cooling blowers. Volumax helps to block roasting immediately.

Ghibli Vortex Drum

The vortex configuration of the drum allows air to enter at a 45° angle at high velocity from four ducts. This creates a unique airflow, moving air in a spiral motion into the drum through the coffee. This configuration uses less air in a more controlled and efficient way. This presents an improvement over the commonly used perforated back plate, which creates an inefficient, uncontrolled flow of air over the beans. Less air means less gas consumption and more aromas, oil and sugar being retained in the roasted beans.

This drum produces noticeable improvements in the quality of the roasted beans, with a clean uniform colour and stain gloss finish. The bean’s colour and appearance are a clear indication of its oil, sugar, and caramel content.

The Perfect Roasting System

Achieving a high level of conductive heat has proved the best method for producing a rich cup, and this is where Coffee-Tech differs from other manufactures. Since conduction is complicated and presents several unresolved issues, many have abandoned it in favour of convective heat. The Ghibli R90 is also equipped with individual frequency inverters for controlling motor speed in all important functions such as the drum rotation, the drum’s airflow blower and the de-stoner.

These features aid in achieving better results in any given condition, including various roasting styles and variations in different beans. The Ghibli R90 roasts continuously, while cooling takes place outside the drum, making it possible to roast up to 135 kg of beans per hour. The Ghibli R90 is user-friendly, ergonomic, quiet and safe. Each function has an individual motor and heat protection.

Ghibli R90 features and high-end construction and craftsmanship. This is a result of 3D CAD design, and the use of high-quality materials, components and precise manufacturing tools assembled and completed by Coffee-Tech Engineering’s passionate artisans. The software simulates a long list of tests prior to production; ranging from stress tests, heat dispersion and load distribution.

The Ghibli R90 is available with various heating methods, from natural gas and LPG to traditional wood and charcoal heating, according to the customer’s preference. Being a high-end roaster, the Ghibli R90 will ensure reliable operation together with consistently superb results for many years.
