Mar 10, 2020· Both rotary evaporators and falling film evaporators are capable of distilling solvent at a relatively high throughput, but one shines through as the clear front runner. An average rotary evaporator will typically have a throughput rate of 5-10 L/hour depending on the size of the condenser and flask, vacuum level, and condensing efficiency.
Segmented evaporator for a smaller temperature difference When falling-film evaporators have to operate with a high dry substance content and concentration rate, such as when they are used as the last but one effect, an increase in the boiling point contributes substantially to the tem-perature difference between heating steam and vapour. In
In beverage field, falling film evaporator is a widely applicable in concentration of glucose, starch sugar, maltose, milk, juice, vitamin C and other aqueous solution. Continuous low-temp evaporation under vacuum to ensure saves energy and time with low loss and convenient to keep product color, taste and nutrition.
These evaporators have long tubes and are most suitable for low temperature appliions. In falling film evaporators uniform distribution of liquid in each tube is the most important feature for efficient performance. SED designed FFE are highly cost effective with optimized feature designing. Tubular Falling Film Evaporator Types:
FilmVap. Proven and reliable, the Alfa Laval FilmVap falling film evaporator effectively concentrates large volumes of low- to medium-fouling liquids – economically and energy-efficiently. Robust and easy to operate and maintain, this multiple-effect, shell-and-tube evaporator takes up less than comparable units, due to its innovative
Falling film evaporators are suitable to treat wastewater with the following characteristics: Liquids that are too viscous for natural circulation. Effluents where the retention time must be minimized. When wastewater composition is sensitive to high temperatures. When excess temperature is critical.
Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the
