Follow the separation objective
An extraction route begins with a defined material and target composition. Pretreatment can include drying and size reduction; extraction then transfers soluble constituents into the selected medium. Filtration or centrifugation removes suspended solids. Concentration, further purification and drying may follow, but liquid products and volatile fractions can follow different routes.
More yield is not always better
Temperature, time, particle size and solvent composition interact with mass transfer and constituent stability. Increasing the mass recovered can also recover more unwanted material. Compare recovery of the relevant constituents, selectivity, energy and solvent demand, and downstream handling rather than treating gross yield as the only objective.
Scale-up requires evidence
Laboratory conditions do not directly establish plant-scale performance. Mixing, residence-time distribution, filter loading and heat transfer change with equipment and batch size. The schematic below deliberately omits temperatures, pressure, solvent ratios and operating instructions: each route needs qualified engineering, safety review and product-specific validation.

The extraction route: English narration
Educational animation with English narration, on-screen text, optional captions and a full transcript below. This is not a real facility or a universal production procedure.
Numbered circles on a pale green background identify eight scenes; a progress strip advances beneath them. The narration reads the following headings and text, without additional technical claims.
0.0–7.8s · Material identity
Confirm the species, plant part and traceable starting lot.
7.8–15.1s · Pretreatment
Drying or size reduction may prepare the material for extraction.
15.1–22.7s · Extraction
A selected medium transfers soluble constituents from the material.
22.7–30.2s · Separation
Filtration or centrifugation can remove suspended solids.
30.2–38.5s · Concentrate / purify
Remove solvent; use selective separation only where needed.
38.5–45.8s · Dry / formulate
Some routes produce powders; others remain liquid.
45.8–53.6s · Quality review
Check identity, composition and agreed acceptance criteria.
53.6–62.7s · No universal recipe
Steps vary by product. This schematic is not a real facility.
