Evaporators | Dairy Processing Handbook

The theory is that if two evaporators are connected in series, the second effect can operate at a higher vacuum (and therefore at a lower temperature) than the first. The vapour evolved from the product in the first effect can be used as the heating medium for the next effect, which operates at a lower boiling temperature due to the higher vacuum.

Multiple Effect Evaporator - Swenson Technology

The last-effect vapor body is maintained at a high vacuum with a steam-jet air ejector or mechanical vacuum pump. The driving force is the pressure drop from the first to the last effect. For the same overall pressure differential and process conditions, the evaporator with more effects will require less steam.

A triple effect forward – feed evaporator is being used to evaporate a milk containing 10 % solids to a condensed milk of 50% T.S. The boiling point rise of the milk (independent of pressure) can be estimated from BPR°C = 1.78x + 6.22x 2, where x is weight fraction of T.S. in milk (K1).Saturated steam at 205.5 kPa (121.1°C saturation temperature) is being used.

Multi Effect Evaporators at Best Price in India

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 .

Rotary Evaporation - Chemistry LibreTexts

This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and solvent trap. Additionally an aspirator or vacuum pump needs to be attached, as well as a bump trap and round bottom flask containing the sample to be concentrated.
