After three months of custom production and rigorous testing, the commercial coffee roaster built for an Argentinian customer is now fully prepared and will soon depart from Shanghai Port. This equipment, integrating precise temperature control technology with the unique characteristics of South American coffee, will serve boutique coffee workshops in Buenos Aires, helping Argentinian coffee beans unleash their unique flavor with the power of Chinese manufacturing.

As a major coffee-producing region in South America, Argentina’s high-altitude coffee beans are renowned for their bright acidity and caramel sweetness, requiring meticulous roasting temperature control. This customized roaster features a three-zone PID temperature control system, enabling precise control of the temperature from 160°C to 230°C with a precision of ±0.5°C, perfectly matching the local light to medium-dark roast requirements. The specially optimized hot air circulation angle (30° inclined air duct) ensures even heating of each bean, resulting in a roasting uniformity of 98%, a 15% improvement over traditional equipment, fully invigorating the beans’ citrus and nutty flavors. The equipment has been fully adapted to Argentina’s voltage standards and operating habits. It adapts to the South American 220V/50Hz power system and is equipped with an intelligent voltage stabilization module to mitigate grid fluctuations. The user interface supports switching between Spanish and English, and includes 18 classic Argentinian coffee roasting profiles, covering varieties such as Caturra and Catuai from the Córdoba region. Operators can access these profiles with a single click, significantly reducing the learning curve. The machine is constructed from food-grade 304 stainless steel, certified for food contact in South America and resistant to corrosion in high-humidity environments.

During the final pre-shipment testing, the technical team simulated the actual operating conditions of an Argentinian coffee workshop. During an 8-hour continuous roasting test, the equipment achieved a stability error of ≤1°C, with bean color deviation within a ΔE range of ≤2, and energy consumption was 20% lower than comparable European equipment. The customized logistics solution included anti-vibration wooden packaging, a temperature monitoring recorder, a Spanish-language operating manual, and a spare parts kit (including heating elements, temperature probes, and other core components). “The Chinese team’s understanding of Argentinian coffee exceeded expectations,” the client manager commented during a video inspection of the machine. Their workshop previously relied on Italian equipment, requiring six months of customization. Once this roaster is operational, daily production capacity will increase to 300 kg, sufficient to supply 20 local specialty coffee shops. The improved flavor consistency is expected to generate a 12% price premium.

To ensure a smooth commissioning, a comprehensive service system has been launched: a partnership with a Buenos Aires-based coffee equipment service provider provides 72-hour on-site response; a Spanish-language technical hotline has been established, supporting remote diagnostics and customizable profiles. The machine also includes an IoT interface for integration with the customer’s production management system, enabling roasting data traceability.

This roaster, about to sail far, represents more than just a delivery of equipment; it also represents a deep dialogue between Chinese and Argentinian coffee culture and technology. We will continue to focus on the unique characteristics of global coffee-producing regions, using customized innovation to allow the unique aroma of coffee from even more regions to shine through Chinese equipment.
