Construction and testing of the new innovative extruder. By the application of a new concept of vital parts od new extruder: innovative active grooved feed section (IAGFS), original rotational barrel segment (ORBS) and special screw (SS) a completely new breakthrough technology of extrusion and design of plasticizing system will be achieved. It will ensure manufacturing the products of improved properties and will enable processing materials that could not be processed so far, as well as food materials, cosmetic and pharmaceutical.
