Overview. The Falling Film Evaporator, with capacity ranges of up to 150t/h and relatively small floor space requirement, is the most widely used evaporator in the process industry. Particularly well suited for temperature-sensitive products, liquids containing small quantities of solids and with a low to moderate tendency to form incrustations.
Jan 04, 2014· Generally, in dairy we can group the falling film evaporators producing the concentrates for the dryers in 2 major groups: Group 1) The multiple effect steam driven thermal vapor re-compression (TVR) falling film evaporator. Typical the TVR evaporators have longer retention times on a higher temperature difference across the evaporator.
Our falling film evaporator is specifically suited to process your products with a low viscosity and a low tendency for fouling. It consists of a tube bundle crowned by a proprietary liquid distribution device that ensures an efficient and uniform distribution of the liquid to all the tubes. Your product flows as a continuous film along the
Oct 09, 2019· A falling film evaporator can be an extremely efficient and effective type of heat exchanger. In fact, many factories across most major industries have been steadily updating their equipment from older rising film …
Our falling film evaporators are currently for sale with great service. A falling film evaporator system mainly consists of several parts. • Evaporator (the heat exchanger), which is used to heat and evaporate liquid materials. • Separator, mainly used to separate the concentrated liquid and the secondary steam generated after heating.
• Preheater, which is used to preheat …
0. A falling film evaporator is a type of heat exchanger that uses a shell and tube design to evaporate heat-sensitive liquids. The feed is pumped into the evaporator from the top. It’s then uniformly dispersed throughout the heating tubes of the device. While partially evaporated, the liquid flows through tubes, forming a thin layer on the
Aug 29, 2019· Natural circulation evaporators are based on the natural circulation of the product caused by the Falling film evaporator. This type of evaporator is generally made of 4–8 m (13–26 ft) tubes enclosed by steam jackets. The uniform distribution of the solution is important when using this type of evaporator.
