Eucalyptus Leaves Orange Color Extraction Plant, Capacity: 10TPD

A natural color extraction plant is a facility designed to extract pigments and dyes from various natural sources such as fruits, vegetables, flowers, and other botanical materials. These extracted colors are commonly used in the food, beverage, cosmetic, and pharmaceutical industries as natural alternatives to synthetic dyes.A Eucalyptus Leaves Orange Color Extraction Plant is an industrial facility designed to extract natural orange dye from the leaves of various eucalyptus species. The orange hues are primarily due to the presence of flavonoids, tannins, and carotenoid pigments in the leaves, with the exact shade and intensity depending on the eucalyptus species, leaf maturity, and extraction conditions.Raw Material: The plant uses fresh or dried eucalyptus leaves, with mature and dried leaves often yielding stronger orange or reddish-orange pigments.Preparation: Leaves are cleaned to remove impurities, then chopped or crushed to increase surface area for efficient extraction.Extraction Methods:Water Extraction (Decoction): Leaves are simmered in water at around 80–90°C (175–195°F) for 1–2 hours, allowing the pigments to leach into the liquid. Prolonged simmering and the presence of both flavonols and tannins can shift the color from yellow to deep orange or orange-brown, especially on protein fibers like wool.Alcohol Extraction: Alcohol-based solvents can be used for stronger pigment yield.Steam Distillation: Sometimes used for simultaneous essential oil and pigment extraction.
