Process for drying fluid and solid material in which a liquid spray is introduced into a drying chamber together with a source of dry desiccating gas such as heated air. A screen is positioned to receive the spray while the droplets are in a tacky condition to form a mat on the screen with a provision for drawing air from the heated enclosure through the mat and thence through the screen for the purpose of drying the mat. At least portions of the mat are subdivided into a particulate form and recirculated back to the inlet of the apparatus where they are mixed with fresh incoming product. |
