Industrial Production Herbal Extraction Production Line

Plant Extraction Production Line — Overview

A standardized industrial production line for natural plant roots, flowers, leaves, fruits and seeds. Through crushing, extraction, concentration, separation, purification and drying, it achieves large-scale production of essential oils, plant extracts, polysaccharides, flavonoids, alkaloids and polyphenols. Available in batch-type or fully automatic continuous configurations, meeting standards for food, health supplements, cosmetics and herbal medicine industries.

I. Process Flow

Raw material pretreatment → Crushing & screening → Solvent / Ultrasonic / Microwave / Cold extraction → Solid-liquid separation → Clarification filtration → Vacuum concentration → Purification (column chromatography / membrane / rectification) → Alcohol precipitation & decolorization → Spray drying / Vacuum drying → Powder packaging.

II. Key Equipment & Functions

  1. Pretreatment: Washing, slicing, crushing (10–60 mesh) and vibrating screening to clean and uniformly size raw materials.

  2. Extraction (Core Unit): Multi-functional 304/316L stainless steel tanks supporting water/ethanol extraction, reflux and percolation. Optional ultrasonic or microwave enhancement for heat-sensitive materials. Multi-tank series/parallel for continuous batch production.

  3. Solid-Liquid Separation: Two-stage filtration: basket filter/plate filter for coarse residues, precision tube filter for fine impurities, preventing downstream scaling.

  4. Vacuum Concentration: Low-temperature negative-pressure evaporation with adjustable concentrate density. Solvent recovery rate >90%. Double/triple-effect units available for large-scale energy-efficient production.

  5. Purification & Refining: Alcohol precipitation tanks, membrane filtration (NF/UF), rectification for essential oils, and macroporous resin columns achieving 50%–98% purity for flavonoids, saponins and alkaloids.

  6. Drying & Powder Production: Vacuum low-temperature dryer for small batches; centrifugal spray dryer (industry standard) for continuous automated powder production with excellent flowability and purity.

  7. Post-Processing & Packaging: Vibrating mill, mixer, automatic filling machine and vacuum packaging. Closed dust-free production meeting food and cosmetics GMP standards.

III. Configuration Options

  1. Small Pilot Line (50–200L): Daily capacity 50–200 kg. Suitable for R&D labs and startup factories. Low investment covering full extraction-concentration-drying process.

  2. Medium Production Line (300–1000L): Daily capacity 0.5–3 tons. Mainstream configuration for food and supplement ingredients. Batch-type automatic control with 24-hour continuous operation.

  3. Large Automated Line (1000L+): Daily capacity 3+ tons. Fully PLC-controlled continuous production with linked feeding, extraction, concentration and drying. Minimal labor for export-grade ingredient factories.

IV. Materials & Compliance

All product-contact parts in SUS304 food-grade stainless steel (316L for pharmaceutical grade). Polished sanitary piping with no dead zones for CIP cleaning. Fully closed production with solvent recovery and explosion-proof configuration. GMP and SC certification compliant.

V. Applicable Raw Materials

Flowers & Leaves: Rose, chrysanthemum, lavender, honeysuckle oils & extracts. Roots: Ginseng, astragalus, pueraria, licorice extracts. Fruits & Seeds: Grape seed, blueberry, sea buckthorn, goji berry extracts. Aromatic Plants: Peppermint, ginger, cinnamon essential oils.
