Vacuum evaporation

There are other advantages, such as the ability to distill liquids with high boiling points and avoiding decomposition of substances that are heat sensitive.

It is also used when boiling a substance at normal temperatures would chemically change the consistency of the product, such as egg whites coagulating when attempting to dehydrate the albumen into a powder.

Traditionally this process was performed in batch mode, but nowadays continuous vacuum pans are available.

[4] It represents a clean, safe and very versatile technology with low management costs, which in most cases serves as a zero-discharge treatment system.

Vacuum evaporation is also a form of physical vapor deposition used in the semiconductor, microelectronics, and optical industries.
