Abstract:
Apparatus for producing and cooling polymer pellets, including the combination ofa die plate and rotary knife extruder for cutting hot pellets and impelling them outwardly in air, a pelletizer head formed to receive and direct a stream of cooling liquid to arrest and envelop the pellets, and a collector having means to receive the pellet-laden stream and a baffle to direct the stream in first and second consecutive horizontal and vertically descending paths and to allow the pellets to cool progressively along said paths, said second path being formed and arranged to invert the stream entering from said first path from top to bottom and to change its horizontal direction of flow, whereby the pellets at the uppermost level of the stream in said first path are inverted to the lowermost level of the stream upon entering said second path.
