[0002] Plastic color master batch is a kind of granular colorant made by uniformly dispersing high-concentration pigment or dye in resin carrier, and is widely used in the coloring of plastic products, with the advantages of uniform coloring, simple operation, environmental protection and high efficiency, and is an important material indispensable in modern plastic industry. As an important auxiliary material of plastic industry, plastic color master batch plays an important role in improving product quality, enriching product color and improving production efficiency. With the continuous progress of technology and the continuous change of market demand, the color master batch industry will usher in a more broad development prospect.

[0003] Plastic color master batch needs to be dried and screened during processing. Drying is to remove the moisture and residual solvent on the surface of color master batch to prevent processing defects (such as color difference, defects, etc.) caused by moisture.
