摘要： Systems and methods to dry workpieces are disclosed. A disclosed example system for drying workpieces that have been applied with a liquid medium includes a workpiece receiving region to receive at least one workpiece to be dried, where the workpiece receiving region is implemented in a vacuum chamber that is closable in a relatively fluid-tight manner, and an evacuation device to evacuate the vacuum, where the evacuation device has a suction pump that is fluidly coupled on a suction side by a fluid line to the vacuum chamber. The workpiece receiving region is positioned in the vacuum chamber of a housing for enclosing a workpiece to be dried. The housing includes a housing wall with at least one passage opening for a gaseous fluid, where the housing has a suction connection, which is fluidly coupled by a suction device to a vacuum container that is ventable by a valve via the suction line to open and block the suction line to generate negative pressure at the suction connection.

摘要： Methods and apparatus to clean and dry cavities are disclosed. A disclosed example tool apparatus includes an inner tube to provide a fluid to the cavity when the tool apparatus is positioned relative to the cavity, and an annular tube surrounding the inner tube, where the annular tube is fluidly coupled to a suction chamber and where the suction chamber is fluidly coupled to a vacuum vessel. The example tool apparatus also includes a valve disposed between the suction chamber and the vacuum vessel.
