5.1 Application: 

Vacuum is often  employed as a process for removing bulk   and absorbed water   (or other solvents) from a product. Combined with heat, vacuum can be   an effective method for drying. High degrees of dryness can be attained at   relatively low temperatures. This allows for fast and effective     drying of temperature sensitive products. Lower  moisture content can be achieved when using vacuum and heat than can be   achieved with heat only       (particularly with parts that are porous or have a very    high surface area). Additionally, drying under a vacuum can prevent oxidation of   sensitive product that cannot be dried in the presence of air. Vacuum drying systems can also recover the solvent    that is removed from the product, if required. Often       the part to be dried is placed       into a vacuum drying chamber. However,   if the part can withstand, and is designed for vacuum, the       inside of the part can be evacuated and dried without the use of a vacuum chamber.

5.2 Description

A vacuum drying system   consists of a vacuum chamber, a   mechanical vacuum pump with gauge and valves as well as a       source for providing heat to the product     to be dried. Both oil-sealed and oil-free (dry)    mechanical       vacuum pumps can be used. .A condensate trap (typically      cooled   to very low temperatures) is also used to pump and trap the     liquid(s) to be removed.   Base pressures    of less than 0.1 Torr are often required, depending on   the  liquid to be removed and the temperatures. Care    should be taken to protect oil-sealed pumps from the liquid and operating the pumps     properly to minimize the impact    of the liquid vapors being ingested into the pump (often with the use of a gas ballast and/or gas purge).

The vacuum drying process often  involves multiple steps     of applying heat  and vacuum. Reducing the pressure (applying vacuum) at the surface of a liquid (such as water)  will allow the liquid to evaporate without elevating       the temperature. The evaporation of the liquid will continue until the       part       is dried or until enough heat is removed (through evaporation) that the remaining liquid freezes. At this point   the drying process continues as       sublimation which is much slower compared to evaporation. In general, this   is not desirable. The purpose of heat is to maximize drying while preventing      freezing of the liquid.             

There are several methods of applying heat to the product being       dried. Some products have temperature limitations which may impact which methods may be employed. These methods include:

•Preheating the  product  using a   variety   of methods prior to placing into     the vacuum chamber.

•Preheating the  product  in a specially       designed vacuum       chamber that is configured to provide convection heating as well as vacuum.
