[0002] Masterbatch, also known as plastic masterbatch, is a plastic processing aid developed in the 1980s. It is composed of excessive amounts of chemical additives, carrier resins and dispersants, and is an aggregate obtained by uniformly loading an excessive amount of pigments (dyes) in the resin.

[0003] The production process of masterbatch is a complex and delicate process, which aims to mix various raw materials and additives evenly to form a granular product with specific properties and functions. After cutting and processing, the masterbatch needs to be heated and dried. The traditional heating and drying is to put the masterbatch into the heating and drying equipment and dry it directly. The heating equipment generally heats the plastic masterbatch by pumping hot air through a hot air blower. This heating method makes the plastic masterbatch in the pile unable to be fully heated, and the heating effect on the plastic masterbatch is not good. The processing time needs to be extended to ensure the processing effect of the plastic masterbatch, thereby reducing the heating efficiency of the device. Utility Model Content
