Vacuum evaporation is a physical vapor deposition process that utilizes the free space of a vacuum environment in order for the material from the thermal vaporization source to reach the substrate. Why this is important is because the collision of the gas molecules will ultimately affect the substrate.
Vacuum Evaporation is a modern, "no-boil" method of wort preparation. See boiling and wort. It is based on the physical relationship between a liquid's boiling temperature and the ambient pressure surrounding it. The object of vacuum evaporation is ecological sustainability achieved by reducing the use of primary energy in the brewhouse.

thermal evaporation sources Resistive Boat or Coil. A pair of high current vacuum feedthroughs are employed to flow a significant current (e.g. 300A) through a wide ribbon of refractory metal (e.g. tungsten, molybdenum) that has been pressed to have a large "dimple" on the top side into which pellets of the material are placed.
sputtering, thermal, and plasma arc deposition methods. At BYU-Idaho the method used to produce thin lms is a thermal evaporative deposition. Thermal evaporation deposition is the most basic method used to produce thin lms. The rst use of the term PVD was used in C. F. Powell, J. H. Oxley, and J. M. Blocher Jr.'s book Vacuum Coatings in 1966 [3].
Thermal Evaporation of Chromium (Cr) Chromium can be problematic to thermally evaporate because it will sublime under high temperatures. In order to perform thermal evaporation, a material's temperature must be raised to the point where its equilibrium vapor pressure is 1E-2 Torr. This provides for good deposition rates in systems with "normal" source-to-substrate geometries.
