Used BALZERS BAK 550 #293641768 for sale

BALZERS BAK 550 is an evaporator designed for the evaporation or concentration of aqueous flow streams. It is a falling-film evaporator equipped with a thin-film evaporator assembly which consists of two plates or two sets of plates. These plates are positioned to form a shallow channel, and the liquid to be evaporated is fed into this channel. The film of liquid that is generated is thin enough to ensure a rapid and efficient evaporation of the liquid. BAK 550 creates a thin film of the incoming liquid by introducing an axial flow of the liquid in the evaporator. As the liquid is accelerated over the plates, it is spread out whilst the mechanical action of the spinning and pitching plates which changes the velocity and the direction of the liquid and creates a thin, uniform film on the plates surface. The evaporation process is regulated by controlling the flow rate of the liquid being fed to the evaporator and its residence time within the thin-film evaporator assembly. The evaporation process can be also regulated by adjusting the temperature and pressure of the liquid. The temperature and pressure of the liquid are regulated by two or more controlling stages along the evaporation sequence. BALZERS BAK 550 is provided with an individual controlling stage for the temperature of the evaporator, the pressure, and the flow rate of the liquid. BAK 550 is also designed to minimize the formation of scale and other fouling on the interior of the thin film evaporator. It is equipped with an appropriate surface state material, such as stainless steel or titanium, that is resistant to corrosion and fouling. The evaporator design is further improved by adding an efficient cleaning system. This system is operated manually or automatically and it is implemented to flush the consumption liquid from the evaporator in order to prevent any buildup of residues or scale. BALZERS BAK 550 is a state-of-the-art evaporator designed for low maintenance and easy operation. It is equipped with various safety systems and its control elements allow for efficient and reliable operation. Its construction and design provides uniformly high thermal efficiency and maximum process flexibility. BAK 550 is suitable for the evaporation of a wide range of solutions and liquids in various industries including food and beverage, pharmaceutical and chemical industries.
