COMPLET Range: Roasting capacity of 600–1,500 kg coffee per hour

A range of specialised roasters for torrefacto and natural coffee, with twin roasting drums: one for natural coffee, and the other for torrefacto. During the torrefacto process, green coffee beans are roasted with sugar, and sometimes other additives. No sugar or additives are used in the production of natural coffee.
Natural coffee is roasted in a roaster exclusively designed for this type of coffee, based on TECAIRE TNA INNOVA model technology.
Torrefacto coffee is roasted in a drum with swinging motion and unperforated sides to ensure effective air flow and airtightness during product processing. The roaster components and drum are manufactured from food grade stainless steel.
TTA Series/COMPLET range roasters are equipped with two independent coolers: one for natural coffee and the other for torrefacto.
Roasting capacity of 600–1,500 kg coffee per hour.
TTA Series/COMPLET roasters can operate at half or full nominal load, at the same roasting temperature and producing the same roast profile. To achieve this, the PLC allows unlimited roast profiles that are automatically adjusted so they can be replicated exactly from one cycle to the next.
Heat is mainly transmitted by convection during operating stages where no sugar is present, and by conduction when sugar is added.
TTA Series/COMPLET equipment operates at sugar levels of up to 30% in standard configuration.

La gama TTA Series / COMPLET está pensada para el tueste de café “torrefacto” y también de café natural, con varios porcentajes de azúcar añadido, y la posibilidad de añadir otros aditivos. El café se procesa mediante dos tambores de tueste, uno para café natural y otro para café torrefacto.

Roast time in TTA Series/COMPLET range roasters is 12–20 minutes Short roast times accentuate acidity in the coffee bean, and longer roasts promote body. The level of sugar added affects roast time: higher levels of added sugar require a longer roast. All roasters in the range can operate at half or full nominal load, and the PLC adjusts times and temperatures for a consistent roast profile.

  • Homogeneous colour thanks to the method of heating the coffee bean, which is mainly convection (heat transfer from hot air) with some conduction (heat transfer from the roasting drum) for a natural roast, and mainly conduction for torrefacto coffee.
  • The two roasting drums are manufactured from carbon steel or food grade stainless steel, with a variety of mixing paddles, in customised materials, available. Coffee moved evenly and carefully in the roasting drums to prevent damage to the bean. The roasting drum used for natural coffee is an unperforated cylinder and for torrefacto, a hemispherical shape, which keeps all the ingredients that make up the torrefacto coffee inside the drum.
  • A door in the roasting drum is opened to empty the natural coffee into the natural coffee cooler
  • Product is transferred into the torrefacto coffee cooler by tilting the drum towards the cooler
  • The door in the torrefacto coffee roasting drum can be opened at any stage of the roasting process to add ingredients and verify the production process
  • Degrees of roast, from light to dark, with the same capacity per cycle.
  • Degrees of roast, from light to dark, with the same capacity per cycle
  • Weight loss from natural coffee depends on the moisture level in the green coffee bean, and can be compensated by the quenching system at the end of the roasting process
  • Practically negligible weight loss from torrefacto coffee, which can be compensated by the quenching system at the end of the roasting process
  • Rapid and careful cooling to prevent damage to the coffee bean Coolers for both natural and torrefacto coffee are manufactured from stainless steel
  • Roasting and cooling cycles are synchronised and occur simultaneously
  • Roasters are equipped with solid particle evacuation cyclones for the coffee cooler, hot air recirculation, electronic burners, and smoke afterburners with catalysts, for both the roaster and the cooler


The TTA Series/COMPLET range is the best solution for high-quality mixed natural and torrefacto coffee batches and flexibility throughout the whole process The design, development and manufacture of the TTA SERIES/COMPLET range meet the most stringent robustness and reliability standards. They are the best solution when a single roaster is required for any type of coffee available on the market, providing practical and extremely functional solutions
All components of the TTA SERIES/COMPLET range are controlled by PLC, with SIEMENS or ROCKWELL HMI and local area or internet PC SCADA for remote access Comprehensive user interface which is programmable, remotely accessible and customisable at all times
There is no limit to the number of recipes that can be stored by the control system, so the roasting process can be adapted to the various roasting profiles required by the production program
TTA SERIES/COMPLET range software includes a product traceability system, which enables batch numbers and process quality to be managed.
Temperature curves and process parameters are visualised and stored in each roasting cycle
