(PDF) Vacuum Drying: Basics and Application

In the nuclear industries, vacuum drying process is an integral component where it is used to remove residual water from the used fuel assemblies and cask /canister prior to dry storage. [4].Drying of Solvents and Laboratory Chemicals - The safest method is to dry in a vacuum desiccator over concentrated sulphuric acid, phosphorus pentoxide, silica gel, calcium chloride, or some other desiccant. Where substances are stable in air and melt above 100°C, drying in an air oven may be adequate. In other cases, use of an Abderhalden pistol may be satisfactory.

Vacuum Drying - an overview | ScienceDirect Topics

In contrast to spray drying, vacuum drying requires a longer time to reach equivalent moisture content although less than for freeze drying. Compared to 24 hours for freeze drying, controlled low-temperature vacuum dehydration of Lb. acidophilus took only four hours to dry Drying Method - an overview | ScienceDirect TopicsDrying Method. Drying methods include high-temperature evaporation in methanol, freeze drying in t-methyl alcohol, supercritical-point drying in CO2, and the use of temporary polymer pillars for support during drying followed by a dry etch removal of the polymer.
