The Genio 6 series was developed by Neil Maree and perfected by the Genio Roasters engineering team. With cutting-edge electronics and superior mechanical systems, the Genio 6 is designed to create specialist temperature and heat transfer profiles. Roasts can easily be duplicated thanks to the machine’s excellent stability and easy to use control system. The Genio 6 is ideal for any type of roastery: from beginners who want to start their businesses to commercial roasters who need to roast specialty batches or test new roasting profiles.

ProRoast App


Our latest ProRoast Touch Screen System puts the operator in complete control of every aspect of the roast.  The 10″ Android tablet allows the operator to move freely about the roaster with a wireless Bluetooth connection.  During a roast, each parameter of the process is monitored and plotted in real-time on the screen.  The app can store around 3000 profiles, and any profile can be re-loaded as the “reference roast” in the background to compare your new roast against in real-time. The app automatically updates over Wi-Fi, ensuring that you always benefit from the latest software and features.

Control & Automation

Our Control Philosophy

Advanced control systems lies at the heart of Genio Roasters.  After years of development and fine-tuning, our latest generation of control and automation systems ensures that the operator always has full control over every aspect of the roast.  Nobody knows better what they need than the roaster master himself, which is why Genio has developed the entire control principle in-house by like-minded roasters such as yourself.  Our control system is incredibly easy to use, adapts to any roasting style or skill level and is can instantly be switched from full manual through various levels of automation, all the way to full profile automation.

How it works

The Genio system works by connecting the roaster’s hardware, sensors and parameters to the operator’s Samsung tablet through Bluetooth.  This provides a stable, wireless touch screen to monitor every aspect of the roast.  Changes to the roaster’s gas pressure, air pressure, drum speed and modes can be set through intuitive dials and buttons on the control panel.  The changes that you make can be monitored on the screen in real-time, and every parameter is recorded into the database for reviewing later.


In Standby Mode, the machine is ready and waiting your command.  If you just finished roasting and switch to Standby at the end of the day, the machine will cool itself down automatically before switching off.


A roaster needs to be perfectly preheated before you can start roasting.  The Prime feature helps by automatically starting your gas burners and drum and fan modes.



Start your roast by switching to Roast mode.  In this mode, you are in complete control.  You can adjust gas burner pressure, drum speeds and air pressure in the drum with 1% steps for perfect accuracy.


Profile mode is Genio’s version of Cruise Control.  In this mode, the machine is in control of the gas pressure and will try to duplicate your reference roast automatically.

Auto Feature

The AUTO feature (Precision and Pro upgrades) on the ProRoast System allows roasters to copy the exact settings from your reference roasts.  For example, you can switch drum speed to Auto and the machine will do the same as you did during your previously recorded reference roast.  You can choose to switch any or all of the dials (gas pressure, drum speed and air pressure) in and out of Auto as many times as you want, whenever you want.  Professionals use Auto for the beginning of a roast before switching the dials back into manual mode at first crack.

But in Profile mode (Precision and Pro upgrades), things get even more interesting. Here, the machine uses advanced algorithms to copy not only your reference profile’s settings but the actual temperature profile as well.  The system will automatically adjust the gas pressure (while keeping your reference profile settings as a baseline) to compensate for environmental, ambient and seasonal changes and thereby duplicating the reference profile’s bean temperature with up to 99% accuracy.

This revolutionary system will ensure that you achieve perfect consistency no matter what, and is a great tool to have if you are the one who sets up the initial roast profiles, and you have a roaster operator who is responsible for the day to day operation of the machine but who does not have the skill and experience that you or your master roaster has.


Heat Transfer

Our unique blend of convection and conduction heating is what makes every Genio the perfect roaster.  Our focus is on convection heat transfer to do most of the roasting. Our burners are positioned so that the flames will never be in direct contact with the drum surface.  Instead, the burner’s energy is used to heat clean air drawn in through special side-mounted air vents.  This results in a sweeter cup with more delicate floral notes, but with the added body and chocolaty notes thanks to the carefully designed conduction heating from the drum’s surface.

Roasting Capacity

Genio’s drums are oversized to resemble that of a traditional 8kg roaster.  With a green bean fill level of only 33% and a roasted bean fill level of only 47%, our drums have more than enough space even at maximum capacity for optimal convection air roasting.

Dual Wall

The drum has 4.5mm inner and 2mm outer carbon steel walls with a 4mm air gap in-between the two layers.  This gap allows air to move freely between the two layers and keeps the inner drum cooler and evenly heated.

Ceramic Coating

We use a special ceramic paint on the outside of the drum.  This type of coating is typically used on race car engines and exhaust systems.  It helps with heat distribution and heat retention, resulting in a perfectly stable and even heat distribution across the entire surface of the drum.

Ceramic Insulation

We use 3-layers of ultra-high temperature ceramic insulation on either side of the drum.  This insulation ensures a stable roasting environment and keeps the heat inside the roast chamber, resulting in reduced energy usage and better consistency between batches.


Our low NOX, silent 25kW atmospheric gas burners ensure precise energy delivery throughout the roast.  They can be modulated from 20% through to 100% in 1% increments: perfect for smaller roasts that need a delicate touch.  The burners are paired with advanced gas valves and a fully automated ignition and flame monitoring system.  This ensure a safe roasting environment with plenty of power for even the fastest 10 minute roast.


Motors and Fans

With direct drive WEG motors, Varvel gearboxes and high performance fans, you can rest assured in the quality of Genio’s drives.  Additionally, our fans have straight radial blades that drastically reduce the buildup of coffee oils, ensuring less maintenance and a longer life span.


We use only the highest quality imported bearings in our machines.  With adjustable position, specially machined housings and high temperature food grade grease, our bearings and drive trains are designed to last for a lifetime.

Cooling Bin

A seamless, aluminium spun bowl is the centerpiece of every Genio.  The material properties of the aluminium coupled with a dedicated, 1600 Pa, 1000m3/hr Elektror cooling fan ensures that our system can cool the beans down to room temperature in as little as 3 minutes.  It’s light weight makes it easy to remove during cleaning and the anodized finish reduces oil buildup on the surface.


The solid stainless steel assembly comes with spring loaded 5mm Teflon scrapers to stir the beans.  Coupled Genio’s unique start-stop feature, our agitator perfectly compliments the cooling bin in style and performance.  It’s screw-less removal system makes cleaning a breeze by simply lifting the entire assembly out for easy access to the cooling fan.



Before you can invest in a coffee roaster, you will need a few things.  This includes Ventilation, Gas and Electrical supply along with sufficient space for your roaster.  We have installed many roasters in everything from private living rooms and garages to commercial coffee shops and industrial roasteries.  Bear in mind that roasting requires enough space to operate your roaster and to store and package all of your coffee.

Your installation site will need to be easily accessible in order to get your roaster delivered.  You Genio 6 can have casters installed to make it easier to move.  Roasters cannot be moved over rough terrain, grass or stairs.  We have installed many roasters in challenging locations, so be sure to contact Genio for advice on where to install your roaster.
