Refractance Window operates at low temperatures without vacuum to rapidly and gently concentrate sensitive, delicate and valuable products. The technology helps retain complex but subtle flavors and aromas, colors and nutrients. According to the company, the evaporator’s heat transfer is 99 percent efficient, making it suitable for removing moisture from high moisture, flowable products. Rapid evaporation occurs when infrared energy from circulating hot water at 210°F (99°C) or lower is transmitted at the speed light directly into the product. Assisted by conducted heat, product moisture rapidly evaporates and is carried away by mechanically boosted airflow. At no more than 140°F (60°C), the product temperature remains lower than circulating water temperature.
