April 30, 2025 – Huilong New Materials (301057) Secures a Key Utility Model Patent for Color Masterbatch Production
Huilong New Materials Co., Ltd. (Stock code: 301057) announced on April 15, 2025 that it has been officially granted a utility model patent titled “A Crystallization Drying Furnace for Color Masterbatch,” with the application number CN202420725307.7. This patent achievement brings fresh technological impetus to the color masterbatch manufacturing sector.
The newly – authorized patent centers around an innovative crystallization drying furnace for color masterbatch, boasting a sophisticated structure and practical functions. The furnace comprises a main body, a feed pipe, a discharge pipe, and a hot air pipe, forming its basic framework. Inside, there are a first mesh plate and a second mesh plate, with the second mesh plate positioned obliquely above the first one. A scraping blade on the upper surface of the first mesh plate can move back and forth with the help of a reciprocating drive mechanism, while a vibration motor connected to one end of the second mesh plate also plays a crucial role during operation.
According to the Color Masterbatch Industry Network, this patented technology offers significant advantages. Color masterbatch enters the area between the first and second mesh plates through the feed pipe, after which the hot air pipe initiates the drying process. Once dried, the color masterbatch, propelled by the hot air flow, passes through the first mesh plate and enters the discharge pipe for output. Meanwhile, new color masterbatch can promptly replenish the furnace through the feed pipe, creating a continuous cycle that remarkably enhances drying efficiency and reduces energy consumption. Moreover, the ingenious design of the scraping blade and the reciprocating drive mechanism is particularly notable. The back – and – forth movement of the scraping blade on the surface of the first mesh plate effectively prevents wet color masterbatch from sticking, ensuring uniform heating and providing a solid guarantee for high – quality color masterbatch production.
