Zusammenfassung:A plant (1) for the continuous manufacture of an expandable plastic granulate (G) is disclosed that includes a plastic melt source (2) for providing a plastic melt (F), an impregnating device (3) for providing an impregnated plastic melt (FB) by impregnating the plastic melt (F) with an expanding agent (B) provided by an expanding agent source, and a granulator (4, 41, 42) for producing the granulate (G) from the impregnated plastic melt (FB) with the granulator (4, 41, 42), with the granulator (4, 41, 42) being fluidly connected to the impregnating device (3). According to the invention, a switching means (5) is provided in such a way, that the plastic melt (F) can be fed to the granulator (4, 41, 42) under bypassing the impregnating device (3). In addition, the invention relates to a method for producing a granulate (G) using a plant (1) in accordance with the invention.
