FAQ For Ultrasonic Acoustochemical Equipment

1.) What is the optimal processing capacity of equipment extraction? What is the best volume of liters?

1, the optimal capacity of the equipment and the production process factors have a great relationship

2, the main factors have a great relationship with ultrasonic power, processing medium, medium temperature, stirring and so on.3. For example, under suitable conditions, loquat leaf polysaccharide extraction was carried out under acoustic chemistry with a power of 3000W, the extraction rate was 94.8%, the extraction time was 30 minutes, and the processing capacity was 0.5-0.8m³.

4. Application examples: Increase the semi-finished product output of Liuwei Dihuang pills, 5m³ volume, a total of 8 sets of 1500W ultrasonic equipment are used, and the extraction rate is increased by 5-10%

5, if it is not sure at present, it is recommended to do a small trial or pilot test, according to the test effect, and then decide the type and power to use.

2.) What frequency of equipment processing effect is better? Why?

1, the ultrasonic equipment used in traditional Chinese medicine extraction, the conventional frequency segment is mainly 20kHz,28kHz,40kHz these three.

2, in the process of traditional Chinese medicine extraction, there are generally certain requirements for the total power, and the power of a single device must reach more than 1500W to have better results.

3, 28k and 40k equipment, due to the high frequency of equipment, small power capacity, a single device can only achieve 500-1000W, not suitable for large-scale industrial use. Overall consideration, the frequency segment of Chinese medicine extraction is generally selected for 20KHz, which has no high-frequency noise, and the maximum power of a single unit can reach more than 3000W, which is high extraction efficiency and suitable for industrial use.

3.) Is it necessary to add other chemical catalysts to extract Chinese medicine?

1, the application of ultrasonic equipment for traditional Chinese medicine extraction, mainly the application of ultrasonic cavitation effect (dissolved micro bubbles in the medium increased under the action of ultrasonic, forming a resonance cavity, and then closed instantaneously, that is, the ultrasonic cavitation effect.) This is a physical process. In theory, the application of ultrasonic extraction of traditional Chinese medicine does not need to add other chemical catalysts.

2, but in the actual use of the process, need to meet the requirements of extraction, generally add a small amount of catalyst or auxiliary equipment, more conducive to the improvement of extraction rate.

4.) What is the processing capacity of a certain power per unit time?

1, the optimal processing capacity of the equipment is related to many factors, and has a great relationship with power, processing media, media temperature and so on.

2, Generally speaking, according to the effect of our application, the extraction time is generally between 30min - 120min. The specific time needs to be tested according to the product and process environment.

3, at present, if the specific parameters can not be determined, it is recommended to do a small or pilot test, according to the test effect, and then decide the model and power to use. The problem of processing capacity is detailed in question "1.)" in this chapter.

5.) What are the advantages of ultrasonic compared with other processes? Won't it backfire?

1, improve extraction efficiency: the unique physical characteristics of ultrasonic wave can promote the plant cell tissue to break the wall or deformation, so that the extraction of traditional Chinese medicine effective components more fully, the extraction rate than the traditional process significantly increased up to 5-100% (depending on the process and material decision);

2, shorten the extraction time: ultrasonic enhanced extraction of traditional Chinese medicine is usually 20-60 minutes to obtain the best extraction rate, the extraction time is greatly shortened by 2/3 than the traditional method, and the raw material processing capacity is large.

3. Reduce the extraction temperature: the optimal temperature of ultrasonic extraction of Chinese medicinal materials is 0-60 ℃, which has a protective effect on the active components of medicinal materials that are unstable in heat and easy to hydrolysis or oxidation, and greatly saves energy and energy; Generally, the extraction temperature is 40-60 ℃, which protects the effective ingredients of traditional Chinese medicine.

4, enhance adaptability: ultrasonic extraction of Chinese herbal medicine is not limited by the polarity of the composition, molecular weight size, suitable for the extraction of most types of Chinese herbal medicine and various components.

6.) If used for extraction, how much is extracted per minute? How to determine the role of ultrasound?

1. Refer to question "1.)" in this chapter for the extraction amount.

2, to determine the role of ultrasonic, our company suggests to do comparative tests, such as: take two of the same raw materials, extraction under the same experimental conditions, one with ultrasonic, one without ultrasonic, and finally test the effect of ultrasonic use. However, in the experiment, it must be noted that because the ultrasonic wave has a heating effect on the liquid, it is easy to lead to an error in temperature. Our company has independent research and development of professional ultrasonic experimental workbench, the internal setting of temperature regulation device, especially suitable for comparing ultrasonic equipment laboratory test.

7.) If it is used for Chinese medicine extraction, which medicinal materials can be extracted?

1. Ultrasonic extraction of Chinese medicinal materials is not limited by the polarity of components and molecular weight size, and is suitable for the extraction of most types of Chinese medicinal materials and various components, such as: extraction of flavonoids, extraction of alkaloids, extraction of saponins, extraction of organic acids, extraction of polysaccharides, extraction of anthraquinones, etc.

8.) What material are the various parts of the equipment processed? Will it react and change with Chinese medicine?

1, the equipment is mainly made of titanium alloy, stainless steel and other materials, unless it encounters a highly corrosive liquid, generally speaking, it will not react with Chinese medicine.

9.) Use environment with a lot of steam. What if there is no compressed air? How to prevent moisture? What about the moisture resistance of the power supply?

1, each component of the ultrasonic equipment is made of materials with good corrosion resistance, according to the actual feedback of a large number of Chinese medicine extraction customers, our ultrasonic equipment can work normally in such an environment. If the humidity is particularly large, some technical measures can be taken to solve the problem, for example, the power supply part can increase the power supply housing with high protection level
