Extraction of Ginsenosides

Production process of membrane separation technology for ginsenosides

Ginseng extract → centrifugation/plate frame → ginseng ultrafiltration membrane filtration system → membrane concentration → resin adsorption → spray drying/freeze drying → finished product

1、 Equipment usage

This equipment is suitable for various processes in industries such as traditional Chinese medicine, plants, biopharmaceuticals, food, and chemical engineering, including atmospheric pressure, micro pressure, water decoction, warm soaking, hot reflux forced circulation, permeation, extraction and concentration of plant essential oils and aromatic oil components, and recovery and concentration of organic solvents. Very suitable for small batch and multi variety production in universities, research institutes, laboratory research and development departments of enterprises and institutions, as well as small and medium-sized pharmaceutical factories.

2、 Equipment features

1. High equipment efficiency: integrating multifunctional extraction, vacuum concentration, and organic solvent recovery, it can perform hot reflux cycle extraction, concentration, conventional extraction, concentration, water precipitation, alcohol precipitation and other operations, simplifying the operating procedures and completing the production processes of extraction, filtration, concentration, and essential oil condensation in one step, greatly saving raw materials and working time. The work efficiency is improved by 20% to 35% compared to general multifunctional extraction equipment

2. High conversion rate of raw materials: During the extraction process, hot solvents (such as water or alcohol) are continuously added to the raw materials, and the active ingredients in the medicinal materials are continuously dissolved through the layer from top to bottom. Increase the effective ingredients in the original drug solution by more than twice compared to regular extraction

3. Concentrate at room temperature to reduce the loss of ethanol during the concentration process. The ethanol recovery rate can reach 95%, and the purity is high, which can be reused, saving costs and reducing the generation of waste liquid.

4. The extraction and concentration efficiency is high, and the raw material solution is circulated in a closed device after one addition. The effective ingredients in the raw materials can be continuously extracted, so the amount of material used in the equipment can save more than 30% of the solvent under the same extraction amount. The production cost of membrane separation and concentration system is about 20% of the cost of steam concentration, which greatly saves the production cost of enterprises and has great technical and economic advantages

5. The extraction equipment and concentration equipment can operate independently or in conjunction during use. The entire extraction, concentration, and recovery process is carried out in a closed flow path

6. The contact parts between the unit and the materials are all made of stainless steel, which can work under negative pressure, normal pressure, and positive pressure. The equipment extraction part is equipped with a large aperture manhole or hand hole to facilitate the collection of drug residues, and is equipped with a dual filtration system to prevent small drug residues from flowing into the concentration tank

7. Membrane concentration equipment has a large processing capacity per unit time, stable flux, and does not change with changes in material properties

8. The equipment is easy to operate, easy to clean, labor-saving, and time-saving.
