TURIN, Italy – Electromagnetic induction represents one of the most revolutionary technologies for industrial heating. Based on the principle discovered by Michael Faraday, this process allows heat to be generated inside conductive materials through interaction with an alternating magnetic field. In induction systems, a power supply sends alternating current to a coil, generating a magnetic field that induces eddy currents in the material, heating it directly and with high precision.
1. Background on electromagnetic induction and how it works
The induction system offers numerous advantages over traditional methods: fast heating times, greater energy efficiency, minimal maintenance and reduced emissions. The technology eliminates the burning of fossil fuels, ensuring a safer and more sustainable working environment.
Sweet Coffee Italia, after several years of research and development, has perfected the application of this technology in coffee roasters. In the last two years, it has successfully launched three models: Gemma 2IND, Gemma 8IND and Gemma 30IND, designed for small, medium and large production volumes.
These successes laid the groundwork for the development of the Gemma 120IND, the first roaster capable of handling up to 120 kg of coffee per batch using only electricity.
2. Heating of the Gemma120IND compared to smaller induction machines from Sweet Coffee Italia
The Gemma 120IND represents a turning point for the roasting industry, incorporating technological innovations that meet the demands of large-scale production. Compared to previous models, this unit introduces a series of design innovations that increase its efficiency, safety and production quality:
1. High-power inductor with liquid cooling: allows for more stable heating management, even during intensive and prolonged roasting cycles, improving efficiency and reducing the risk of overheating.
2. Syncron permanent magnet motors: guarantee extremely high precision in controlling the movement of the drum and other mechanical components. Thanks to their innovative construction, these motors do not suffer during long use and do not require cooling, ensuring optimal performance, increased reliability and reduced maintenance costs.
3. Automated radiant tube cleaning: thanks to an electrical automation system, maintenance is optimised, improving overall system efficiency and ensuring consistent performance over time.
4. Loading hopper automation: opening and closing are fully electrified, making the process safer and faster, and reducing human intervention.
5. New cooling system for coffee: uses electromagnetic vibration to oscillate the beans, allowing uniform and rapid cooling. This approach eliminates the use of mechanical carousels, reducing safety risks and clutter, as well as minimising product waste.
These innovations place the Gemma 120IND among the most advanced machines in the industry, not only for its production capacity up to 120 kg per cycle, but also for its energy efficiency and high automation, which guarantee reduced operating costs and increased reliability.
Note: The company does not show images of the Gemma120IND as it will be premiered at Sigep Rimini 2025 (18-22 January).
3. The historical importance of the technology and overcoming limitations in roasting systems
With the Gemma 120IND, Sweet Coffee Italia has overcome one of the most significant historical limitations of electric roasting systems: the difficulty of handling high volumes without compromising energy efficiency or product quality. Thanks to the scalability of electromagnetic induction technology, it is now possible to roast large quantities of coffee with minimal environmental impact.
Conventional systems, based on fossil fuels, suffer from high operating costs, harmful emissions and difficulties with temperature control. The Gemma 120IND, on the other hand, not only eliminates direct combustion, but also reduces CO and NOx emissions to negligible levels. This innovation satisfies the most stringent environmental regulations, while providing energy savings and increased work safety.
Thanks to the introduction of advanced motors and the electromagnetic cooling system, the machine has set new technological standards that reduce environmental impact and improve roasting quality. This achievement marks a milestone for the roasting industry, opening up new opportunities for roasters of all sizes.
The Gemma 120IND is not just a machine, but a symbol of what technological innovation can achieve when guided by a clear vision: combining productivity, quality and sustainability. Thanks to electromagnetic induction technology and innovations such as the electromagnetic vibration cooling system, this roaster sets new standards for the coffee industry, removing the limitations of traditional methods and offering a greener, better-performing future.
With this launch, Sweet Coffee Italia confirms itself as a leader in the transformation of the industry, laying the foundations for an era in which large production runs will be just as sustainable as smaller ones. The Gemma 120IND is not just a step forward: it is a revolution.
