The photos show the new FFE outside the main building near the existing evaporator station, which originally had five effects. Given its age and the high annual repair and maintenance costs, it was not possible to continue using all apparatus in this station, and an upgrade became necessary. The logical conclusion was to rely on the new FFE, using it as the first effect, with each of the remaining four effects being set back by one effect. Especially because our customer is hoping to enjoy all the benefits of an FFE from BMA: low steam consumption, reduced formation of colour, and far smaller sugar losses.
Commissioning in summer 2018 went smoothly. The FFE quickly achieved a heat transfer coefficient of more than 2,226 W/m²K and evaporation rates of more than 100 t/hr. The temperature difference between the heating steam and vapour was less than 7.7 K.
The FFE has been our technology of choice for evaporator stations for many years. It offers higher heat transfer coefficients, even at low temperatures, and permits a smaller loss of pressure. Our specially developed juice distributor plays a key role in keeping retention times of the juice in the FFE short. And it ensures the juice is evenly distributed across all heating tubes.
