Roasters for the Black Gold Specialty Coffee Line

The Black Gold line was developed for those who work with specialty coffees and need a roaster capable of delivering absolute profile control, repeatability, and superior quality in every batch. Maintaining the same technological principle as SIATEC roasters, Black Gold uses a fluidized-bed roasting system and a single furnace, ensuring thermal stability, consistent curves, and a high standard of uniformity—essential factors to preserve the coffee’s aroma, sweetness, and sensory complexity.

Above-average extraction with a focus on consistency

The key differentiator of the Black Gold line is its ability to deliver a technically precise roast, with a high level of control and uniformity, resulting in coffees that are more balanced and with better sensory expression in the cup. This enables the production of microlots and commercial lots with the same level of care, maintaining the standard demanded by the specialty market.

Technical differentiators of the Black Gold Line

1) Larger-diameter cooling screen

Black Gold features a cooling screen sized to increase the contact area between cold air and the beans. In practice, this brings direct gains to final quality:

• Faster and more uniform cooling, reducing the risk of “carryover roasting” after discharge
• Ability to cool a larger quantity per batch with stability
• Reduced excessive piling, ensuring air reaches the lower layers of coffee as well

2) High-efficiency bottom-mounted exhaust fan (suction cooling)

Another important highlight is the exhaust fan located at the bottom, a key element for efficient suction-based cooling. It pulls ambient (cool) air through the bean bed and expels hot air outward, which supports:

• Faster temperature drop after roasting
• Superior standardization between batches
• Greater process safety and quality control
