Description

Technical Field

[0001] The utility model relates to an intelligent frequency-variable ultrasonic extraction module and an ultrasonic extractor thereof, belonging to the technical field of traditional Chinese medicine extraction equipment. Background Art

[0002] Ultrasound-Assisted Extraction (UAE) is a technique that uses the mechanical action and acoustic cavitation effects of ultrasound to extract target components from various matrices. This technique has been widely used in recent years, particularly in the food, pharmaceutical, and biotechnology sectors.

[0003] In recent years, ultrasonic extraction technology has continued to develop, and many new ultrasonic extraction methods have emerged, such as variable frequency ultrasound and hybrid technology combining low-frequency, high-power ultrasound with high-pressure technology. These new technologies have further improved extraction efficiency and extract quality, and broadened the application range of ultrasonic extraction.

[0004] Ultrasonic extraction works on two main principles: first, acoustic cavitation. When ultrasound waves propagate through liquids, they form tiny bubbles that grow and collapse under periodic changes in acoustic pressure. The high-temperature, high-pressure microenvironment created by the bubble collapse helps destroy cell walls and release cellular contents. Second, the mechanical effect: the vibration and shear force of ultrasound waves enhance the permeability of the solvent, accelerate the diffusion of solutes, and improve extraction efficiency.

[0005] Although ultrasonic extraction technology has the advantages of high efficiency, energy saving and environmental protection, it still has some shortcomings and challenges in practical application. The following are some of the main problems of ultrasonic extraction technology:

[0006] Although ultrasonic extraction generally improves extraction efficiency, its effectiveness is affected by multiple factors, such as ultrasonic frequency, power, extraction time, temperature, and solvent type. Optimizing these parameters requires extensive experimentation, and different substances may require different optimization conditions, increasing the complexity of research and application.

[0007] Although ultrasonic extraction is usually performed at relatively low temperatures, the mechanical action of ultrasound and the acoustic cavitation effect can generate localized high temperatures, which can lead to the degradation of certain heat-sensitive substances. Therefore, special temperature control is required during the extraction process to protect these active ingredients.

[0008] Ultrasonic extraction technology is highly effective at the laboratory scale, but its application on an industrial scale still faces challenges. For example, the propagation and uniformity of ultrasound waves in large-scale systems are difficult to control, which may affect the extraction effect. In addition, the energy output and processing capacity of ultrasonic equipment need to be further improved for large-scale application.

[0009] Standardization of the ultrasonic extraction process and reproducibility of results remain a challenge. Different laboratories and equipment may produce different extraction results.

[0010] Therefore, there is an urgent need for an intelligent frequency-variable ultrasonic extraction module and an ultrasonic extractor thereof to solve one or more of the above-mentioned technical problems. Utility Model Content

[0043] The utility model has the following beneficial effects:

[0044] The efficiency of variable frequency ultrasonic extraction is higher than that of ordinary ultrasonic extraction. The main reason is that variable frequency technology overcomes the limitations of ordinary ultrasonic extraction at a fixed frequency by adjusting the frequency of ultrasonic waves, thereby improving the extraction efficiency. The following are the specific reasons:

[0045] 1. Optimization of frequency regulation

[0046] Resonance frequency matching: Different substances have different cell structures and molecular vibration characteristics. Variable frequency ultrasound can better match the resonance frequency of the substance by adjusting the frequency, thereby improving extraction efficiency.

[0047] Avoid standing waves: At a fixed frequency, ultrasonic waves may form standing waves in liquid media, resulting in uneven energy distribution and affecting extraction results. Variable frequency ultrasonic waves avoid standing waves by continuously changing the frequency, making energy distribution more uniform.

[0048] 2. Improve cavitation effect

[0049] Enhanced cavitation effect: Variable frequency ultrasound increases the number of bubble formation and collapse by continuously changing the frequency, thereby enhancing the cavitation effect and further improving the extraction efficiency.

[0050] Multi-frequency resonance effect: Under variable frequency ultrasonic conditions, ultrasonic waves of different frequencies act simultaneously to form a multi-frequency resonance effect, which further enhances the cavitation effect.

[0051] 3. Enhance mechanical and thermal effects

[0052] Enhanced mechanical effect: Variable frequency ultrasound can enhance the micro-flow and shear force of the liquid medium, making it easier for the solvent to penetrate into the cells and accelerating the release of the target substance.

[0053] Thermal effect optimization: Variable frequency ultrasound can optimize the thermal effect and make the local temperature more uniform through frequency adjustment, thereby improving the extraction efficiency.

[0054] 4. Adapt to different extraction stages

[0055] Multi-stage optimization: The extraction process is usually divided into multiple stages, including cell wall disruption, component dissolution, diffusion, etc. Variable frequency ultrasound can dynamically adjust the frequency according to the needs of different stages to optimize the extraction effect of each stage.

[0056] Reduce solvent viscosity: Variable frequency ultrasound can reduce solvent viscosity through thermal and mechanical effects, improve the solvent's penetration and dissolving ability, and thus improve extraction efficiency.

[0057] 5. Improve system stability

[0058] Reduce equipment fatigue: Variable frequency ultrasound reduces the continuous working time of ultrasonic equipment at a fixed frequency through frequency changes, reduces equipment fatigue, extends equipment service life, and improves the stability and continuity of the extraction process.

[0059] Improved energy transfer: Variable frequency ultrasound optimizes the energy transfer path through frequency changes, allowing ultrasonic energy to be transferred to the extraction medium more efficiently, thereby improving the overall extraction efficiency.

[0060] 6. Wider adaptability

[0061] Adapt to different substances: Variable frequency ultrasound can adapt to target substances of different types and structures through frequency adjustment, thereby improving the extraction efficiency of different substances.

[0062] Adapt to different solvents: Variable frequency ultrasound can adapt to different types of solvents through frequency adjustment, improve the solubility and penetration ability of the solvent, and thus improve the extraction efficiency.

[0063] In short, variable frequency ultrasonic extraction technology optimizes the physical and chemical effects of ultrasound through frequency regulation, overcomes the limitations of ordinary ultrasonic extraction, and thus significantly improves the extraction efficiency.

[0064] The utility model mainly includes two parts: an ultrasonic extraction tank and an intelligent variable frequency control panel. The ultrasonic extraction tank contains a metal temperature probe for temperature detection; a heating copper sheet is set on the inner wall of the ultrasonic extraction tank for temperature control; a steel plate with a vibrating surface is provided at the bottom of the ultrasonic extraction tank, and an ultrasonic generator and an ultrasonic transducer are set under the steel plate.
