Technical Field

[0002] Complex natural green pigments are colorants composed of a variety of natural pigments, characterized by their natural color and strong stability.

The surface of the processing tank 1 is provided with a drive mechanism, and the right side of the crushing box 4 is provided with a crushing component.

[0021] Specifically, the drive mechanism consists of a first servo motor 18, a worm gear 19, and a worm wheel 20.

[0024] In use: First, the plant material for pigment extraction is put into the crushing box 4.

After purification, opening the solenoid valve 6 allows the pigment liquid to be discharged through the discharge pipe 5. This achieves the goal of facilitating continuous extraction and purification of composite natural green pigments, avoiding the problem of significantly reduced pigment production and processing efficiency caused by existing pigment extraction and purification processes being carried out in different steps, and thus solving the problems mentioned in the background technology.
