A Single Effect Evaporator Costs Rs. 100,000 And A .

A single effect evaporator costs Rs. 100,000 and a two effect evaporator costs Rs. 200,000 for identical duty. The annual steam cost for single effect is Rs. 25,000 and for double effect it is Rs. 5,000. Depreciation is calculated on a straight line basis, assuming a tenyear service life and zero salvage value.

The Single Effect Evaporator Vacuum Evaporation Heat Transfer in Evaporators Condensers. Frequently in the food industry a raw material or a potential foodstuff contains more water than is required in the final product. When the foodstuff is a liquid, the easiest method of removing the water, in general, is to apply heat to evaporate it.

Multiple Effect Evaporators. Two or more evaporator units can be run in sequence to produce a multiple effect evaporator (shown on the right). Each effect would consist a heat transfer surface, a vapour separator, as well as a vacuum source and a condenser. The vapours from the preceding effect are used as the heat source in the next effect.

Multiple-effect evaporator - Wikipedia

Multiple-effect evaporator - Wikipedia

A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the .
