When industrial precision reveals the identity of every coffee
An industrial coffee roaster requires knowledge, sensitivity and technology to reproduce the same quality batch after batch while preserving the identity of every coffee.
This is the purpose of the TecAIRE TNA ACCURA series: to support coffee professionals who want to increase production while retaining control over their roasting profiles.
Designed for natural coffee bean roasting, this range of industrial coffee roasters combines traditional drum-roasting technology with modern control systems. Its objective is simple: to help every bean express its potential while delivering the consistency required in professional production.
Growing without losing your coffee's signature
Increasing production raises an essential question for every roaster: how can you produce more without changing the flavour that distinguishes your brand?
Moving to a higher-capacity industrial coffee roaster machine is not simply a matter of multiplying the volume of an existing profile. Thermal inertia changes, airflow behaves differently and the beans respond in new ways. A seemingly small variation can affect the colour, acidity, body or aromatic development of the finished coffee.
The TNA ACCURA series was created to facilitate this transition. It provides industrial capacity while maintaining the sensitivity needed to work with coffees from different origins.
The roaster can therefore focus on what matters most: developing a coherent profile and protecting the sensory identity of the product.
Technology designed for origin coffees
Not all green coffee beans react to heat in the same way.
Density, moisture, altitude, botanical variety and processing method all influence the coffee roasting process. A high-altitude washed coffee does not require the same approach as a denser natural coffee or one with a higher concentration of sugars.
The TNA ACCURA range is particularly well suited to roasting by origin. It enables natural coffees to be processed without additives, with the profile adjusted to suit the characteristics of each batch.
This flexibility is valuable both for roasters seeking to highlight a single-origin coffee and for companies that need to maintain consistent quality on a larger scale.
The drum at the heart of aromatic development
In a coffee roaster, the quality of heat transfer determines much of the final result.
The ACCURA series combines heat transferred by conduction through the roasting drum with heat transferred by convection through the flow of hot air. This combination encourages an even distribution of energy throughout the roast.
The drum is fitted with mixing paddles designed to produce a smooth, regular movement of the beans. The coffee circulates evenly, reducing the risk of scorching, uneven development or physical damage.
The aim is not merely to achieve a uniform colour. It is to obtain consistent aromatic development across the entire batch.
Light or dark profiles without sacrificing control
Every market has its preferences. Some consumers look for the brightness and complexity of a light roast, while others prefer the body and intensity of a darker profile.
The TNA ACCURA can produce different types of coffee roast with the same batch capacity. Roasting times can be adapted to the sensory target: shorter cycles generally emphasise acidity, while longer development times enhance body.
This versatility allows the roast master to explore different curves without changing equipment. The machine becomes a genuine creative tool, not merely a means of production.
Consistency from half load to full load
One of the most common challenges in industrial roasting appears when batch volume changes.
A profile developed for a full load does not automatically produce the same result with a half load. The amount of energy absorbed, the rate of temperature increase and the airflow can completely alter the behaviour of the coffee.
TNA ACCURA coffee roasters can operate with either half loads or full nominal loads. The PLC adjusts time and temperature parameters to help standardise the results of the roasting profiles.
This capability provides valuable flexibility for businesses that need to:
- produce products with different rates of sale;
- launch new coffees without committing to a full load;
- respond to fluctuations in demand;
- organise production more efficiently;
- maintain consistency across different batch sizes.
Automation does not remove the roaster from the process. It provides the tools needed to reproduce professional decisions with greater precision.
Two models for different production targets
The series includes two main configurations:
| Model | Capacity per cycle | Indicative cycle time |
| TNA-60 ACCURA | 30–60 kg | 12–20 minutes |
| TNA-120 ACCURA | 60–120 kg | 12–20 minutes |
Depending on the roasting conditions, output can range from approximately 210 to 420 kg of roasted coffee beans per hour.
These options allow each business to select an industrial coffee roaster suited to its actual production requirements, without unnecessarily oversizing the installation.
Rapid cooling to stop the roast at the right moment
The profile does not end when the coffee leaves the drum.
If the beans are not cooled rapidly, residual heat continues to transform the product. A few extra seconds can alter both the colour and the sensory development achieved during roasting.
The TNA ACCURA series incorporates a circular cooler, available in an open or enclosed configuration and with the option of a dual extraction system. Roasting and cooling cycles can be synchronised and carried out simultaneously.
This stage helps stop the thermal reactions at the intended moment while handling the roasted coffee beans gently.
Process equipment designed for daily production
A reliable industrial machine should not be judged solely by the quality of its first batch. It must maintain its performance throughout a complete production day.
The TNA ACCURA series can incorporate:
- a progressive low-emission burner;
- a PLC with a colour human-machine interface;
- a chaff collector;
- a circular cooling system;
- an optional green coffee preheating system;
- an optional smoke afterburner, with or without a catalyst.
These elements help control the process, organise production and meet the operating requirements of a professional coffee facility.
Who is the TNA ACCURA designed for?
This range is particularly relevant for:
- micro-roasters moving towards semi-industrial or industrial production;
- brands developing a portfolio of origin coffees;
- companies seeking greater batch-to-batch consistency;
- roasters producing several profiles in different volumes;
- professionals who want to combine a traditional process with modern control;
- facilities that need to increase capacity without losing their sensory identity.
Before choosing an industrial coffee roasting machine, it is important to analyse current production, growth targets, the coffees being processed, the desired profiles and the available space.
The best machine is not necessarily the largest. It is the one that integrates correctly into the process and supports the long-term development of the business.
Technology serving the roaster's expertise
Roasting remains a profession based on sensitivity, experience and decision-making. No automation can replace knowledge of the bean or the roast master's ability to create an aromatic identity.
As production grows, however, technology becomes essential for turning this expertise into repeatable results.
The TecAIRE TNA ACCURA coffee roaster brings these two worlds together: the tradition of drum roasting and the precision of industrial control.
Because producing more should never mean giving up what makes a coffee unique.
