Abstract:
1. A device for producing pellets comprising: a. a perforated plate with openings from which a melt is extruded; b. a cutting device for cutting strands of the melt extruded from the perforated plate into pellets; c. a process chamber into which the melt is extruded, wherein the process chamber comprises: d. a conveying device for delivering the process fluid into the process chamber through the inlet, and for carrying the process fluid with the pellets contained therein away from the process chamber through the outlet; e. a three-way valve between the inlet channel, a process fluid supply line, and a process fluid discharge line leading downward from the three-way valve, wherein the three-way valve is located below the level of the inlet and below the lowest level of the process chamber; and f. a pneumatic device connected to the process chamber through a valve on the outlet channel wherein the pneumatic device is configured to provide compressed air the process chamber for expelling the process fluid from the process chamber through the inlet opening, the inlet channel, the three-way valve, and the process fluid discharge line to empty the process chamber of the process fluid.
