Ultrasonic extraction equipment uses ultrasonic technology to extract water-soluble substances from biological tissues such as Chinese herbs and plants at room temperature. It has the advantages of short extraction time, low temperature, low impurity content, and high efficiency. Ultrasonic waves propagate in the extraction medium that transmits sound, causing mechanical, thermal, and cavitation effects that break, emulsify, and dissolve solid particles and biological tissues in the medium. This not only maintains the activity of biological tissues, but also greatly improves the uniformity of the extraction medium.

The advantages of ultrasonic extraction equipment include high efficiency, environmental friendliness, easy operation, easy maintenance, short extraction time, low temperature, low impurity content, high efficiency, comprehensive functions, high level of intelligence, and wide adaptability.

Ultrasonic extraction is a discipline designed based on the existence status, polarity, solubility, and other factors of active ingredients and groups of active ingredients in a substance. The new process of extracting by rational use of ultrasonic vibration allows the solvent to quickly enter the solid substance, and the organic components contained in the substance are dissolved as completely as possible in the solvent, resulting in a multi-component mixed extraction solution. The use of ultrasonic technology to enhance the extraction and separation process can effectively improve the extraction and separation rate, shorten extraction time, save costs, and even improve product quality and yield.

Ultrasonic extraction (also known as ultrasonic extraction) has been widely used by conscious individuals for the extraction of effective content in traditional Chinese medicinal materials and various animals and plants due to its unique advantages of low extraction temperature, high extraction rate, and short extraction time. It is a modern high-tech means that replaces traditional cutting techniques to achieve efficient, energy-saving, and environmentally friendly extraction. Ultrasonic extraction has two meanings: the application of ultrasonic technology and the extraction of chemical components. A new extraction technology that utilizes special effects such as cavitation generated by ultrasound to quickly and efficiently extract the chemical components contained in herbals plants.

Principle:
Ultrasonic extraction equipment utilizes the mechanical, cavitation, and thermal effects of ultrasound to extract bioactive components by increasing the velocity and penetration of medium molecules.
Mechanical effect
The propagation of ultrasonic waves in a medium can cause vibration of medium particles in their propagation space, thereby enhancing the diffusion and propagation of the medium. This is the mechanical effect of ultrasonic waves. Ultrasonic waves generate a radiation pressure during propagation, which propagates along the direction of sound waves and has a strong destructive effect on materials, causing deformation of cell tissues and denaturation of plant proteins; At the same time, it can also provide different accelerations to the medium and suspension, and the velocity of the medium molecules is much higher than that of the suspension molecules. Thus, friction is generated between the two, which can cause biomolecules to dissociate and dissolve the active ingredients on the cell wall faster in the solvent.
Cavitation effect
Under normal circumstances, some microbubbles are more or less dissolved inside the medium, and these bubbles vibrate under the action of ultrasound. When the sound pressure reaches a certain value, the bubbles increase due to directional diffusion, forming a resonant cavity, and then suddenly closing, which is the cavitation effect of ultrasound. When this type of bubble closes, it generates thousands of atmospheres of pressure around it, forming micro shock waves that can cause the rupture of plant cell walls and the entire organism. The entire rupture process is completed in an instant, which is beneficial for the dissolution of active ingredients.
thermal effect
Like other physical waves, the propagation of ultrasound in a medium is also a process of energy propagation and diffusion. That is, during the propagation of ultrasound in a medium, its sound energy is continuously absorbed by the particles of the medium, and the medium converts all or most of the absorbed energy into thermal energy, resulting in an increase in the temperature of the medium itself and the medicinal tissue, and an increase in the dissolution rate of the active ingredients. Due to the instantaneous increase in internal temperature caused by the absorption of sound energy, the biological activity of the extracted components can be maintained unchanged.

Advantages:
1. High extraction efficiency: The unique physical properties of ultrasound can promote the breaking or deformation of plant cell tissues, making the extraction of effective ingredients in traditional Chinese medicine more complete, and the extraction rate is significantly increased by 50-500% compared to traditional processes;
2. Short extraction time: Ultrasonic enhanced traditional Chinese medicine extraction usually achieves the best extraction rate in 24-40 minutes, greatly reducing the extraction time by more than 2/3 compared to traditional methods, and processing a large amount of raw materials for medicinal herbs;
3. Low extraction temperature: The optimal temperature for ultrasonic extraction of Chinese medicinal materials is between 40-60 ℃, which has a protective effect on the active ingredients in medicinal materials that are unstable, easily hydrolyzed or oxidized when exposed to heat, and greatly saves energy and consumption;
4. Wide adaptability: Ultrasonic extraction of Chinese medicinal materials is not limited by component polarity or molecular weight, and is suitable for the extraction of the vast majority of types of Chinese medicinal materials and various components;
5. The extracted medicinal solution has fewer impurities and the effective ingredients are easy to separate and purify
6. The extraction process has low operating costs and significant comprehensive economic benefits;
7. Easy to operate, convenient equipment maintenance and upkeep.
Ultrasonic extraction equipment, with its unique physical characteristics and technological advantages, is widely used in fields such as biology, medicine, food, and chemical engineering.
