A herbal extraction and concentration line extracts active compounds from herbs with a solvent (water, ethanol or glycerin), filters out residue and concentrates the liquid under vacuum at low temperature into extract paste, essence or syrup. Closed, automated systems protect heat-sensitive compounds and help meet GMP expectations.
What the line does
It is an integrated set of industrial equipment that extracts actives from natural herbs, removes unwanted impurities and concentrates the solution into herbal extract, essence or syrup. It shortens processing time, raises throughput and supports hygiene, and suits medium and large plants.
How it works
- Preparation: washing, removal of impurities, grinding or cutting to increase contact area.
- Extraction: solvent (water, ethanol, glycerin) dissolves the actives in an extraction tank with controlled temperature and pressure.
- Filtration: mechanical filters or industrial membranes remove plant residue and unwanted components.
- Concentration: vacuum or evaporative concentration at low temperature preserves sensitive actives and yields a dense, high-concentration product.
Benefits
- Extraction efficiency: maximum recovery of actives with less loss.
- Product quality: valuable compounds are retained while impurities and microorganisms are removed.
- Lower operating cost: high automation shortens the process and reduces labor dependence and errors.
- Wide applications: herbal extracts and essences, natural cosmetics, dietary supplements; examples include turmeric and ginger extracts and cordyceps, and compounds such as flavonoids, alkaloids and polysaccharides.
Selection tips
- Match capacity to production scale.
- Prefer durable, safe materials, usually high-quality stainless steel.
- Require precise temperature and pressure control and a high level of automation.
- Check warranty and technical support from the supplier.

Frequently asked questions
Why concentrate under vacuum?
Vacuum lowers the boiling point, so the liquid can be concentrated at low temperature and heat-sensitive actives are preserved.
Which solvents are used?
Commonly water, ethanol and glycerin, chosen according to the target compounds.
