In the first step (67), at least two housing containers (1, 1') which may be evacuated are provided, connected in parallel to a housing container (2) for the second stage (68). An arrangement (70) is provided, by means of which an alternating batchwise charging of the housing container (2) of the second stage from the housing containers (1, 1') of the first stage is carried out. Said arrangement (70) controls discharge bodies (75) of the housing container (1, 1') of the previous stage (67), which is supplied through a channel (3). In said channel each housing container (1, 1') of the preceding stage (67) is provided with an isolating body (71). The arrangement (70), for alternating batchwise charging of the housing container (2) of the last stage, controls said isolating bodies (71). The method for the preparation of recyclable thermoplastic plastic materials by means of such a method provides for an alternating and as continuous as possible charging of the housing container (2) of the last stage from the housing containers (1, 1') of the previous stage (67).
