Tubular falling film evaporators are widely accepted as the optimum type of evaporators for the concentration of most of the products within the dairy and food industry, pharmaceutical industry and within many sectors of the chemical industry. The liquid feed is distributed as a thin film inside a battery of verical tubes, and while the film is falling down through the steam heated tubes, water is eavporated from the film. Vapour from one effect is utilized as the heating medium in the following effect. A typical industrial-size falling film evaporator comprises equipment for pretreatment & pasturisation, 3-6 evaporator effects & equipment for after treatment, condensation & water cooling. Fitwell Engineering offer & supply a comprehensive selection of falling film evaporators, designed to meet almost any requirements of products viscosity, thermal characteristics, degree of concentration & rate of production.
