The main chamber of the heated screen changer during normal production consists of two screen plungers, each with a filter chamber. The melt flow is divided into two streams into the filter chamber and is guided through each of the two screen chambers. The screen needs to be changed after the set pressure drop (4p) has been reached during screen change. The plunger with the replaceable filter element moves out of the main chamber so that the screen chamber reaches the screen change position and the dirty screen is removed and replaced with a new one. During the screen change, the screen chamber of the other plunger remains in the production position and the melt flow is not interrupted. Fifty percent (50%) of the filter area remains available for filtration. Thanks to a special venting procedure, no air enters the process after the screen change.
