All rotary dryers have the feed materials passing through a rotating cylinder termed a drum.It is a cylindrical shell usually constructed from steel plates, slightly inclined, typically 0.3-5 m in diameter, 5-90 m in length and rotating at 1-5 rpm.It is operated in some cases with a negative internal pressure (vacuum) to prevent dust escape.

An integral part of the freeze-drying process is the vacuum system.Proper operation of a freeze dryer requires some basic knowledge of the design considerations as well as the operation and maintenance of the vacuum system.This paper explains the basic parameters and calculation methods used in determining the evacuation rate of a vacuum chamber.
