January 4, 2025 – In a recent announcement, the National Intellectual Property Administration has revealed that Changzhou Shengya Plastic Masterbatch Co., Ltd. has been granted a utility model patent for their “Rotary Drying Apparatus for Color Masterbatch,” with the application dating back to April 2024.
This patent marks a significant breakthrough in the field of color masterbatch production technology, presenting a novel approach to drying masterbatch efficiently. The apparatus ingeniously integrates dispersion and drying functionalities through a series of meticulously designed components.

According to industry insiders at the Color Masterbatch Industry Network, the heart of this rotary drying apparatus lies in its dispersion-drying mechanism, which comprises two main sections: the dispersion unit and the drying unit. The dispersion unit includes a feed hopper, a reduction gear motor, a rotating disc, and a drying chamber, all engineered for precision and ease of operation.
During operation, color masterbatch is initially loaded into the feed hopper. Under the action of the rotating disc, the masterbatch is evenly distributed through multiple outlets at the bottom of the hopper into various drying chambers.
Inside the drying chambers, the masterbatch is skillfully agitated by paddle plates, ensuring maximum exposure to hot air for swift and uniform drying. Once the drying process is complete, a simple valve control allows the masterbatch to effortlessly fall into a collection tray, completing the entire drying and collection cycle.
The advent of this patented technology has not only significantly enhanced the drying efficiency of color masterbatch but also effectively minimized clustering, enabling better exposure of the masterbatch to hot air for optimal drying results. For color masterbatch manufacturers, this innovation is undoubtedly a highly practical and valuable addition to their production processes.
