The core process of the tinctural extractor is to use high concentration alcohol as the solvent, and efficiently dissolve and concentrate plant active ingredients into tinctures through soaking/ultrasound/hot reflux and other methods.

Tinctures are liquid preparations that extract active ingredients from herbs using alcohol as a medium. They are widely used in the production of health wines, traditional Chinese medicine extraction, spice blending, and health products. Unlike industrial grade solvent extraction (such as tantalum niobium and cesium metal extraction), tincture extraction focuses more on the retention and safety of natural components. 95% ethanol or vodka is commonly used as the extraction solvent, with low operating temperature, short cycle, and no need for complex separation and purification.

The principle of tincture extraction machine is to accelerate the release, diffusion and dissolution of effective substances in cells through the cavitation effect, mechanical effect and thermal effect generated by ultrasonic waves, thus significantly improving the extraction efficiency.

process flow
1.Raw material pretreatment
Plant materials need to be dried and crushed to 20-60 mesh to increase specific surface area and improve extraction efficiency;
It is recommended to use dried flowers for aromatic materials such as Xinyi flower buds to avoid diluting alcohol concentration with water.
2.Solvent preparation and feeding
The alcohol concentration is usually 70-95%. If the concentration is too low, it will affect the extraction rate, while if it is too high, wax impurities may precipitate;
The ratio of solvent to raw material mass is commonly 5:1-10:1 (such as 1kg of medicinal herbs+5L of alcohol).
3.Extraction execution (three mainstream methods)
Static soaking method: Soak in a sealed container at room temperature for 14-21 days, shake regularly, suitable for small batch household/fragrance blending use;
Ultrasound assisted method: using cavitation effect to accelerate cell wall breaking, conventional several day extraction can be completed in 30-60 minutes;
Hot reflux method: Heating to 50-65 ℃ and circulating reflux for 1-3 hours, high efficiency but temperature control is required to prevent loss of volatile components

4. Solid liquid separation
Using filter cloth for initial filtration and centrifuge for fine filtration (speed ≥ 3000rpm) to remove residue and suspended particles;
Some high-end equipment integrates vacuum filtration modules to shorten separation time and reduce oxidation.
5. Concentration and filling (optional)
If high concentration tinctures (such as 1:1 or 1:2) are required, alcohol can be concentrated at a low temperature of ≤ 40 ℃ using a rotary evaporator;
Finally, the bacteria were removed by a 0.22 μ m microporous membrane and filled into brown glass bottles for dark storage
