What is the ultrasonic Extraction Machine ?

Ultrasonic vitamin extraction is a method of extracting vitamins from various biological raw materials using ultrasonic technology. The following is a detailed introduction from the aspects of principle, advantages, and process:

Generally, the plant raw materials are pre-treated by crushing to increase the contact area with the solvent. Then the pre-treated plant raw materials are mixed with the selected solvent in a certain proportion and placed in an ultrasonic extraction device. Under the action of ultrasound, the active ingredients in the plant cells gradually dissolve into the solvent. After the extraction is completed, the extract is separated from the residue by filtration, centrifugation, etc. to obtain a crude extract containing active ingredients, which can be further purified and refined as needed.

Raw material preparation: Select biological raw materials rich in target vitamins, such as fresh fruits, vegetables, grains or microorganisms, and perform pretreatment, including washing, chopping, drying, crushing and other operations, to increase the contact area between the raw materials and the solvent and improve the extraction efficiency.

Extraction solvent selection: Select a suitable solvent according to the properties of the target vitamin. For example, for water-soluble vitamins, polar solvents such as water and ethanol-water solution are more commonly used; for fat-soluble vitamins, non-polar solvents such as n-hexane and petroleum are often used.

Ultrasonic extraction: Mix the pretreated raw materials and solvents in a certain proportion and put them into the ultrasonic extraction equipment. Set appropriate ultrasonic parameters, such as frequency, power, extraction time and temperature, and start the equipment for extraction.
Extraction liquid separation and purification: After the extraction is completed, the extract is separated from the residue by filtration, centrifugation and other methods to obtain a crude extract containing vitamins. In order to obtain a higher purity vitamin product, the crude extract needs to be further purified, such as by distillation, extraction, chromatography and other methods.
Cell disruption: When ultrasonic waves propagate in a liquid medium, cavitation effects will occur. In the negative pressure phase of the ultrasonic wave, tiny cavitation bubbles will form in the liquid, and in the positive pressure phase, the cavitation bubbles will close quickly, generating instantaneous high pressure and local high temperature up to thousands of atmospheres. This strong impact force can destroy the cell walls and cell membranes of biological cells, and release substances such as vitamins in the cells into the surrounding solvent.
Accelerate mass transfer: The mechanical vibration of ultrasonic waves can accelerate the material transfer process between the solvent and the biological raw materials. It allows the solvent molecules to penetrate into the raw materials more quickly, and also promotes the vitamins released from the cells to diffuse into the solvent faster, thereby improving the extraction efficiency.
Reducing surface tension: Ultrasonic waves can reduce the surface tension of the solvent, making it easier for the solvent to wet the biological raw materials, further promoting the contact and interaction between the solvent and the raw materials, and facilitating the dissolution and extraction of vitamins.

Application
Pharmaceutical industry: In the production of vitamin drugs, ultrasonic extraction can be used to extract vitamins from natural raw materials as active ingredients of drugs, such as extracting B vitamins from yeast and extracting vitamin E from plant oils and fats.
Health care products industry: Used to produce vitamin health products, extract vitamins from natural plants or animal tissues, and make various vitamin tablets, capsules, oral liquids and other products to meet people's demand for vitamin supplements.
Food additives: Extracted vitamins can be used as food additives to fortify foods, such as adding vitamins to beverages, dairy products, cereal products, etc. to improve the nutritional value of food.
