This invention discloses a solid-phase thickening reactor for PETG chips, belonging to the field of polyester chip processing technology. It includes an outer cylinder with an inlet pipe and an outlet pipe installed at its top and bottom, respectively. Support legs are installed on the side of the outer cylinder. Inside the outer cylinder are a supporting cylinder and four movable inner cylinders. Connecting rings connect the supporting cylinder to the movable inner cylinders and between adjacent movable inner cylinders. This invention ensures that each chip can undergo sufficient and uniform heat exchange with the heat medium, eliminating heating "dead zones" and temperature differences in traditional equipment. Based on the synergistic effect of uniform dispersion, controllable feeding, and a three-dimensional thermal field, the raw material can undergo a thickening reaction in the reactor in an optimal state. This ensures the uniformity and thoroughness of the reaction, effectively avoiding quality problems such as chip viscosity differences and yellowing caused by uneven heating or inconsistent reaction times. Therefore, it significantly improves the final product quality, production efficiency, and batch stability of the PETG chips.
