The Essentials of Continuous Evaporation | AIChE

Vacuum systems also remove noncondensible gases that originate as dissolved gases in the feed or from air leaking into the evaporator body. Most evaporation systems include either a direct or indirect water-cooled condenser to condense the vapor leaving the last evaporator effect. This increases the vacuum of the system. Evaporators that use .

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.
