Description

Technical Field

[0001] The utility model relates to the field of masterbatch particle processing, and particularly relates to a masterbatch drying device. Background Art

[0002] In the production of plastic masterbatch, the preliminarily processed masterbatch particles are obtained by melting large plastic raw materials into a fluid paste state through high-temperature heating, then extruding the plastic in the paste state into small strips through basic equipment, and cutting the strip-shaped plastic with a cutter to form masterbatch. At this time, the masterbatch still has a certain temperature. Since the stacking of masterbatch is likely to cause the heat of the masterbatch itself to be not easily dissipated, resulting in the possibility of adhesion. Generally, the production process is to input the high-temperature masterbatch into a cold water pool to achieve the purpose of cooling. At this time, the collected masterbatch contains a lot of moisture. Therefore, the dehydration and drying of the cooled masterbatch particles have become the next processing step, which invisibly increases the cost of masterbatch production. Therefore, dehumidifying the masterbatch particles after cooling with cold water has become an important step essential before packaging. Content of the Utility Model
