HYBRID APPARATUS FOR DRYING AND IMPREGNATING POLYMERIC PELLETS FOR MANUFACTURING OF FOAMED POLYMER ARTICLES

摘要

The present invention relates to a device for drying and impregnating a material with a fluid blowing agent, having a blowing agent source (13) for providing a fluid blowing agent (20), a first vessel (11) set up to dry a material (22) with the fluid blowing agent (20) or a drying gas (25) and to load the dried material (23) with the fluid blowing agent (20) at a pressure of at least 2 bar, wherein the first vessel (11) can be flow-connected to the blowing agent source (13) or to the blowing agent source (13) and a drying gas source (17) for provision of the drying gas (25), and a dryer (14) for removing water (27) from the fluid blowing agent (21) or the drying gas (26), wherein the dryer (14) can be flow-connected to the first vessel (11).
