Sep 05, 2015· Overview of a multiple effect evaporators. This feature is not available right now. Please try again later.

The number of effects in a multiple-effect evaporator is usually restricted to seven because after that, the equipment cost approaches the cost savings of the energy-requirement drop. There are two types of feeding that can be used when dealing with multiple-effect evaporators.

Manufacturer of standard and custom multiple effect forced circulation, falling film and rising falling film evaporators. Used for evaporation of products such as diaphragm cell caustic, fish stick water, gelatin, soup stocks, sulfates, glues, sugar esters, tomato paste, yeast cream, caustic soda, sorbitol, fruit juices, sucrose and corn steep water.

Jan 11, 2014· Multiple effect evaporator Advantages Suitable for large scale & for continuous operation. Highly economical when compared to single effect. Multiple effects, or stages, are now used to minimize the energy input required to evaporate or boil off undesirable water content. The total evaporation achieved in these systems is approximately the ...

The concentration is made in several evaporators connected in series called multiple effects. The juice travel from one vessel/body to another with a decrease in juice boiling temperature because of the gradual increase of vacuum. In Savannah Sugar Company, quadruple effect evaporation is used with five evaporator bodies, two bodies in the first

Apr 06, 2018· Initial heat input to the plant at for example 92 o C, is used to evaporate and condense water in multiple effects, with the temperature being downgraded in each effect while the heat is recycled. This multiple effect process enables one unit of heat to produce four units of volume reduction as shown the process diagram below.

for condensation of the vapors is only one of the advantages of using multiple-effect forced-circulation evaporators, as the same effect can often also be reached by using an evaporator with a mechanical vapor recompression, if the boiling point elevation of the final product solution is not excessively high. A plant consisting of multiple ...

The multiple-effect configuration combines two or more evaporator bodies to conserve steam, which is condensed in the first-effect heat exchanger only. Water evaporated in the first-effect vapor body is condensed in the second-effect heat exchanger, which provides energy for evaporation in the second-effect vapor body (and so on for additional ...

• single and multiple-effect evaporators (remove water from liquid) • batch still (separate a mixture of miscible components) • tray columns for distillation (separate a mixture of miscible ...

Reusing evaporated solvent as heating medium, higher steam economies are achieved. This method of increasing utilization of steam is used in multi-effect evaporator. In multi-effect evaporator vapor from the first effect is passed over to the next effect in which …
