Agitated thin-film evaporators have a wide processing flexibility, and a single system can often be designed to process different products under varied operating conditions (6). Normally, a thin-film evaporator is operated under reduced pressures in the range of 2–250 mmHg abs. Either steam or liquid heating medium is used to heat the evaporator.

An evaporator is a device, majorly a type of heat exchanger, used in an industrial process to separate the liquid, mainly water, from a chemical compound into gas or water vapor. Evaporators are commonly used in food industry to concentrate the food by evaporating the water content from the food.

An evaporator is to concentrate 10% wt caustic soda solution to 50% wt. Feed enters at 100F Steam is available saturated at 50 psig and the evaporator can be operated at 9.96 psi vacuum. OHTC of the evaporator is 500 BTU/hft F a) Determine the heating area required for the production of 10,000 lb/h of the 50% wt NaOH b) What is the steam economy?

As the feed travels down the tube, evaporation occurs. The vapor/liquid mixture travels down the remaining tube length and into the vapor head. The vapor is removed through the top of the vapor head, while the liquid exits out the bottom. YouTube.

Example 1: A single effect evaporator is to be used to concentrate a food solution containing 15% (by mass)dissolved solids to 50% solids. The feed stream enters the evaporator at 291 K with a feed rate of 1.0 kg s −1. Steam is available at a pressure of 2.4 bar and an absolute pressure of 0.07 bar is maintained in the evaporator.

The key parameter when designing the evaporator is the exchange area required for evaporation. Both mass and energy balances must be considered when calculating this area. Thus, for an evaporator into which a flow F is fed and two flows (the concentrate S and distillate E) are removed, as shown in the figure:
