Ultrasonic Herbal Extraction Line

Introduction

The Ultrasonic Herbal Extraction Line is a continuous/batch type complete set of equipment that integrates ultrasonic assisted extraction, concentration, and solvent recovery. The typical model supports a volume of 100-1000L and a power of 300-3000W, and is widely used for efficient extraction of plant active ingredients such as flavonoids, polysaccharides, and essential oils.,etc

The Ultrasonic Herbal Extraction Line is a modern equipment that uses high-frequency ultrasound (usually 20-40 kHz) to accelerate the dissolution of plant active ingredients. Through the cavitation effect, mechanical vibration, and thermal effect of ultrasound, the plant cell wall is destroyed, promoting efficient contact between solvents and target components. This technology is suitable for extracting active ingredients from industries such as traditional Chinese medicine, health products, cosmetics, etc., such as alkaloids, flavonoids, essential oils, etc

Core advantages
1. Efficient extraction rate
The cavitation effect of ultrasound can penetrate the cell wall, increasing the extraction rate by 50-500% compared to traditional methods such as hot reflux, and shortening the extraction time to 30-60 minutes (traditional methods require several hours to several days).
Dynamic hot reflux and ultrasound collaborate to achieve synchronous and efficient extraction of multiple components.
2. Low temperature energy saving and environmental protection
The working temperature should be controlled at 40-60 ℃ to avoid degradation of heat sensitive components such as vitamins and antioxidants.
Reduce energy consumption by 30-50%, decrease solvent usage, and support organic solvent recovery system.
3. Intelligence and flexibility
Equipped with a PLC control system, pressure, temperature, and frequency parameters can be customized to adapt to the characteristics of different medicinal herbs.
Modular design supports upgrading to a microwave ultrasound collaborative integrated system.
4. Material and safety
The entire process uses food grade 304/316L stainless steel, which complies with GMP certification, is corrosion-resistant, and easy to clean.
Sealed explosion-proof design, suitable for environments with flammable organic solvents

The Ultrasonic Herbal Extraction Line is a continuous/semi continuous system that integrates ultrasonic assisted extraction, dynamic reflux, solvent recovery, concentration and separation. It is widely used in the industries of traditional Chinese medicine, health products, cosmetics and natural products. Its core advantages lie in low-temperature and efficient wall breaking (below 45 ℃), shortened extraction time (30-60 min), and improved yield of active ingredients (such as flavonoids, essential oils, etc.), saving about 30-50% energy compared to traditional decoction or hot reflux methods

process flow
preprocessing
Crush the raw materials to 20-60 mesh to increase the contact area.
ultrasonic extraction
The medicinal herbs and solvents (water, ethanol, etc.) are put into the extraction tank, and the ultrasonic generator (power 500W-20kW) is started with a frequency of 40 kHz for 30 minutes.
The cavitation effect generates microjets, which penetrate the cell wall and release intracellular components.
Dynamic cycle and concentration
The extraction solution is circulated and filtered by a pump, and enters a vacuum concentration tank. The solvent is evaporated at low temperature (≤ 60 ℃) and concentrated to the target density.
Solvent recovery and drying
Organic solvents are recycled through a condensation recovery system; Concentrated solution spray dried or freeze-dried into powder

Application scenarios
Pharmaceutical and Health Products
Efficiently extract active ingredients such as flavonoids (such as Ginkgo biloba leaves) and saponins (ginseng) for use in capsules and oral liquids.
Natural cosmetics
Extract plant essential oil (rose, lavender) and antioxidant ingredients for essence liquid and facial mask.
food industry
Preparation of natural sweeteners (steviol glycosides), pigments (anthocyanins), and functional beverages.
Research and small-scale production
Laboratory grade equipment (such as 100L small wires) supports new drug research and customized production
