Abstract
An apparatus for continuously introducing a substance in liquid phase into plastics granules includes a supporting structure adapted to support in series and in substantial vertical alignment a feeding section, at least one mixing chamber, and at least one drying chamber. The feeding section is provided with means for feeding the granules to at least one spraying chamber provided with means for spraying the substance onto the granules. The at least one mixing chamber of the granules partially or totally coated with the substance includes substantially static mixing means supported in the at least one mixing chamber. The at least one drying chamber is adapted to receive a predetermined amount of the granules coated with the substance. The substantially static mixing means may include, for example, at least one static mixer, a plurality of mixing bars, or at least two superimposed groups of mixing bars.
