The patent application (Publication Number: US20230374266A1) describes a system for purifying plant juice containing pigments to produce a crystalline product. The system includes a purifier device with a polymeric membrane system for ultrafiltration and diafiltration, a conveyor belt with a top surface to receive the liquid feed, heating trays to heat the feed, and a mill for milling the crystalline product. Additionally, the system may involve processes like adsorption/desorption chromatography, fermentation, or fluid extraction. The conveyor belt is made of plastic, and air blowers are used to move water vapor away from the surface.
The polymeric membrane system, specifically a polyethersulfone (PES) spiral ultrafiltration membrane, is designed to separate sugar from pigments in the juice. The resulting crystalline product has a particle size between 50 and 425 µm, less than 8% moisture, and a color intensity higher than the original juice. The product can be a water-soluble powder with glassy, angular crystals, potentially comprising pigments like anthocyanins, carotenoids, or chlorophyll derivatives. The system aims to efficiently produce high-quality crystalline pigments or colorants from plant juice, particularly algae-derived, through a series of purification and processing steps outlined in the patent claims.
