This invention discloses an integrated deodorization and circulation homogenization
system for plastic granules. The
system features a two-stage partition within the post-
drying chamber, dividing the chamber into three independent cavities: an outer partition, a middle partition, and an inner partition. Two sets of coils enable differentiated
airflow to each zone, creating a tiered temperature field. The middle partition contains multiple spiral tracks, which, along with the V-shaped guide channel and vertical
discharge port at the bottom of the outer partition, direct the
material flow. The first coil provides lateral
airflow, propelling the granules spirally upwards along the tracks, enhancing VOC and
odor removal in the high-temperature range near the
softening point. The second coil provides tangential
airflow along the conical second partition, creating a swirling flow that allows the granules to undergo tiered cooling and deep deodorization in the low-temperature range. This solution solves the problems of traditional equipment, such as single
temperature control, uneven material heating, insufficient air-material contact, and easy agglomeration. It ensures orderly
material flow, uniform deodorization, and high
temperature control accuracy, guaranteeing product quality and production efficiency, and is suitable for large-scale
continuous production of various types of plastic granules.
