A Curcumin Extraction Plant is designed to extract curcumin, the active compound found in turmeric (Curcuma longa), which is known for its anti-inflammatory, antioxidant, and potential health benefits. The extraction process typically involves separating curcumin from turmeric rhizomes or turmeric powder using various extraction methods. The plant setup includes equipment for preprocessing, extraction, separation, and purification.

Key Components and Equipment

1. Raw Material Handling:

• Turmeric Storage : Facilities for storing turmeric rhizomes or powder before processing.
• Feed Preparation : Equipment for cleaning, grinding, or milling turmeric rhizomes into a powder if necessary.

2. Extraction Equipment

• Extraction Vessel :The main equipment where the extraction of curcumin takes place. This can be a batch or continuous extractor, depending on the process used.
• Solvent Extraction System : Involves using solvents like ethanol, acetone, or hexane to extract curcumin. This system includes solvent tanks, pumps, and extraction columns.
• Supercritical Fluid Extraction (SFE) : An alternative method using supercritical CO₂ to extract curcumin. Requires high-pressure vessels and CO₂ pumps.

3. Separation and Filtration:

• Filtration Units: Used to remove solid residues from the extract. Types include centrifuges, filter presses, or membrane filters.
• Centrifuges: Separates curcumin-rich liquid from the residual solid material.

4. Evaporation and Concentration:

• Evaporators: Concentrate the curcumin extract by removing excess solvent. Types include rotary evaporators or falling film evaporators.

5. Purification:

• IPA Distillation Columns: Used for purifying curcumin from other compounds. Methods include column chromatography, high-performance liquid.

6. Drying:

• Drying Equipment: Removes residual solvents and water from the purified curcumin extract. Types include spray dryers or vacuum dryers.

7. Control and Monitoring Systems:

• Instrumentation and Control: Includes sensors, control panels, and software for monitoring and controlling the extraction process parameters.

8. Waste Management:

• Waste Treatment: Facilities for handling and treating waste generated during the extraction process, including spent solvents and solid residues.
• Grinding: Mill turmeric rhizomes into a fine powder to increase the surface area for extraction.
