Abstract
An apparatus (1) for degassing molten plastic material, which comprises:- a treatment chamber (2) provided with at least one entry port (3) associable with supply means (4) for a flow of molten plastic material containing a gaseous component, at least one exit port (5) for the material and at least one suction opening (6) for the at least partial suction of the gaseous component which is in fluid communication with means for applying a controlled pressure, the molten plastic material being in transit through the treatment chamber (2) from the at least one entry port (3) toward the at least one exit port (5) along a first transit direction (D1) and the at least one suction opening (6) being interposed between the ports along the first transit direction (D1), and- extraction means (7) for the molten plastic material which are associated downstream of the at least one exit port (5) for removing the material along a second transit direction (D2), and which comprise a substantially cylindrical jacket (8) extending along the second transit direction (D2) and provided with at least one entry opening (9) which is associated in communication with the at least one exit port (5) and at least one exit opening (10), a transfer screw (11) for the molten plastic material, which is supported in rotation about its own longitudinal axis inside the jacket (8) between the entry opening (9) and the exit opening (10), and rotational actuation means (12) for the screw, an annular channel (13) being defined between the outer surface of the transfer screw (11) and the inner wall of the jacket (8) for the passage of the molten plastic material from the entry opening (9) towards the exit opening (10) along the second transit direction (D2); anddetection means (14) for a measured value (P<sub>MES</sub>) referring to the pressure of the molten plastic material inside the annular channel (13), which are functionally associated in input with electronic management and control means adapted to compare the measured value (P<sub>MES</sub>) with a reference value (P<sub>REF</sub>).
