Longtotem congratulated Nanning Xingjing Technology Co., Ltd. on its application for the patent of a plant decoloration chromatography resin column, which was granted the national utility model patent by the China National Intellectual Property Administration. The authorization announcement number is CN222488989U.

Through the official website of the China National Intellectual Property Administration, Longtotem Network learned from the utility model authorization announcement released on February 18, 2025 that the patent application number/patent number of the utility model is 202420914844.6, and the technical field involves B01D15/10; The utility model relates to a plant decolorization chromatography resin column, which is composed of Ji Yongxian; Qin Xiuping; Wang Kemeng completed the design and research, and submitted the patent application to the China National Intellectual Property Administration on April 29, 2024.

This utility model discloses a plant decolorization chromatography resin column, which relates to the technical field of plant decolorization equipment, comprising a chromatography column shell, a top cover, and a base. The top cover and the base are respectively connected to the top and bottom ends of the chromatography column shell. The top chromatography column, at least one middle chromatography column, and the bottom chromatography column are sequentially arranged from top to bottom inside the chromatography column shell. The top chromatography column, middle chromatography column, and bottom chromatography column are sequentially inserted from top to bottom. The bottom ends of the bottom chromatography column, top chromatography column, and middle chromatography column are all equipped with filter screens, which solves the problem of unstable decolorization effect and ineffective decolorization efficiency of the chromatography column on plants caused by the overall high resin column inside the chromatography column in the prior art. Maximizing and when it is necessary to replace the low position macroporous resin, The technical issue of the need to excavate all large pore resins, resulting in wastage of labor and material costs for the enterprise.

The utility model discloses a plant decolorization chromatography resin column in the claims: 1. A plant decolorization chromatography resin column, characterized by comprising a chromatography column shell 1, a top cover 2 covering the top of the chromatography column shell 1, and a base 3 connected to the bottom of the chromatography column shell 1; The shell 1 of the chromatography column is equipped with a bottom chromatography column 4, a top chromatography column 5, and at least one middle chromatography column 6; The bottom chromatography column 4 is located inside the chromatography column housing 1 near one end of the base 3, and its end away from the base 3 is provided with a first annular protrusion 7. The top chromatography column 5 is located inside the chromatography column housing 1 near the top cover 2, and its end away from the top cover 2 is provided with a first annular groove 8. The middle chromatography column 6 is located near the bottom chromatography column 4, and its end near the top chromatography column 5 is provided with a second annular groove that is compatible with the first annular protrusion 7, and its end near the top chromatography column 5 is provided with a second annular protrusion 9 that is compatible with the first annular groove 8. Groove adaptation; The top chromatography column 5, at least one middle chromatography column 6, and the bottom chromatography column 4 are sequentially inserted through the first annular groove 8, the second annular protrusion 9, the second annular groove, and the first annular protrusion 7; The bottom chromatography column 4, top chromatography column 5, and middle chromatography column 6 are each equipped with a filter screen 10 at one end near the base 3; The bottom end of the top cover 2 is located inside the outer shell 1 of the chromatography column and rests against the top chromatography column 5.
