The frequency of sound waves that human ears can hear is 20-20000 Hz, and when the vibration frequency of sound waves is more than 20000Hz, human ears cannot hear. Ultrasound is known for its lower frequency limit approximately equal to the upper human hearing limit. Therefore, we refer to sound waves with frequencies above 20000 hertz as "ultrasound". Ultrasonic waves are mechanical waves, and mechanical vibrations and waves are the physical basis for the action of ultrasonic waves.

Ultrasonic emulsification realizes ' water-in-oil ' emulsification, ' oil-in-water ' emulsification, ' water-in-oil ' emulsification, ' mixing homogenization of a dispersed phase and a ' continuous ' phase by using ' cavitation effect ' of ultrasonic waves, and is a modern sonochemical means for replacing traditional emulsification processes such as a propeller, a colloid mill and a homogenizer.

The production of medicines usually needs to extract components from natural products, and the process needs to crush, stir, dissolve, emulsify and the like medicinal materials, and the ultrasonic wave can realize the emulsification effect by the cavitation effect and has high emulsification quality, so that a crushing and emulsification extraction device is designed.

Example 1

Referring to fig. 1 to 5, the present embodiment provides a natural product ultrasonic circulation extraction apparatus, including,

the supporting assembly 100 comprises a supporting frame 101, wherein a placing hole 102 is formed in the supporting frame 101, and a supporting shell 103 is arranged at the placing hole 102;

a discharge pipe 206 is arranged at the bottom of the shell 201 close to the side, a motor shaft 207 penetrates through the center of the bottom of the shell 201 and is arranged in the stirring cavity 203, and a driving motor 208 is arranged at the end part of the motor shaft 207;

the other end of the motor shaft 207 is provided with a first crushing piece 301, the top cover 202 is provided with a second crushing piece 302, and the first crushing piece 301 is matched with the second crushing piece 302;

the holder case 103 is provided with an ultrasonic generating member 104.

The invention adopts ultrasonic extraction technology to extract medicinal components, wherein ultrasonic refers to electromagnetic wave with the frequency of about 20 kHz-50 MHz, and the ultrasonic is a mechanical wave which needs an energy carrier-medium to be transmitted. The ultrasonic waves have positive and negative pressure alternating cycles in the transmission process, and extrude medium molecules in the positive phase, so that the original density of the medium is increased; in the negative phase, the medium molecules are sparse and discrete, and the medium density is reduced.

That is, the ultrasonic wave does not polarize molecules in the sample, but generates acoustic cavitation between the solvent and the sample, resulting in the formation, growth and explosive compression of bubbles in the solution, thereby dispersing the solid sample, increasing the contact area between the sample and the extraction solvent, and increasing the mass transfer rate of the target from the solid phase to the liquid phase.

In industrial application, ultrasonic wave is used for cleaning, drying, sterilizing, atomizing, nondestructive testing and the like, and the ultrasonic wave is a mature and widely applied technology. The principle of ultrasonic extraction the superiority of ultrasonic extraction of Chinese medicinal materials is based on the special physical properties of ultrasonic. The solid-liquid extraction separation is realized mainly by reducing the acting force between the target extract and a sample matrix through the quick mechanical vibration wave generated by the piezoelectric transducer.

When ultrasonic waves with the acoustic wave frequency higher than 20KHz are propagated in a continuous medium (such as water), the medium particles (including particles of important effective components of medicinal materials) are caused to move on a propagated wave front according to the Huygens fluctuation principle, so that the medium particles move by huge acceleration and kinetic energy. The acceleration of the mass point can be calculated to be more than two thousand times of the gravity acceleration.

The medium particles act on the particles of the effective components of the medicinal materials to obtain great acceleration and kinetic energy, which can quickly escape from the medicinal material matrix and dissociate in water.

Ultrasonic wave is transmitted in a liquid medium to generate a special 'cavitation effect', the 'cavitation effect' continuously generates countless micro-air holes with the internal pressure reaching thousands of atmospheric pressures and continuously 'explodes' to generate microcosmic strong shock waves to act on the traditional Chinese medicinal materials, so that medicinal material components are bombarded to escape, a medicinal material matrix is continuously corroded, and medicinal components which do not belong to a plant structure are continuously separated. Accelerate the extraction of the effective components of the plants.

The ultrasonic vibration homogenization (sonification) makes the action on each point in the sample medium consistent, so that the whole sample is extracted more uniformly. In conclusion, the effective substances in the traditional Chinese medicinal materials can be used as medium particles to obtain self huge acceleration and kinetic energy under the action of an ultrasonic field, and strong external impact is obtained through the cavitation effect, so that the effective substances can be efficiently and fully separated.

The ultrasonic extraction is suitable for extracting effective components of Chinese medicinal materials, and is a new method and process for preparing Chinese medicinal materials by thoroughly changing the conventional water decoction and alcohol precipitation extraction method. Compared with the water boiling and alcohol precipitation process, the ultrasonic extraction has the following outstanding characteristics (taking the ultrasonic extraction of the honeysuckle extract as an example):

(1) high temperatures are not required. The ultrasonic wave is used for strengthening extraction at the water temperature of 40-50 ℃, the water boiling is not carried out at high temperature, and certain medicinal components with the characteristics of heat instability, easy hydrolysis or oxidation in the traditional Chinese medicinal materials are not damaged. The ultrasonic wave can break the wall of plant cell and improve the curative effect of Chinese medicine. (2) The normal pressure extraction has good safety, simple and easy operation and convenient maintenance.

(2) The extraction efficiency is high. The best extraction rate can be obtained after the ultrasonic wave enhanced extraction is carried out for 20-40 minutes, and the extraction time is only one third or less of that of a water boiling and alcohol precipitation method. The extraction is sufficient, and the extraction amount is more than twice of that of the traditional method. According to statistics, the working efficiency of the ultrasonic wave at 65-70 ℃ is very high. The effective components of the Chinese herbal medicine plants are basically not damaged within 65 ℃.

After ultrasonic wave is added (under the condition of 65 ℃), the effective components of honeysuckle are extracted for about 40 minutes. The cooking time of the cooking method is usually two to three hours, which is more than 3 times of the ultrasonic extraction time. Extracting for 3 times per pot, and extracting more than 90% of effective components.

(3) Has broad spectrum. The applicability is wide, and various components of most plant raw materials can be prepared into natural products through ultrasonic extraction.

(4) The energy consumption is reduced. Because the ultrasonic extraction does not need heating or the heating temperature is low, the extraction time is short, and the energy consumption is greatly reduced.

(5) The processing capacity of the raw materials of the medicinal materials is large and is improved by times or several times, the impurities are few, and the effective components are easy to separate and purify.

(6) The extraction process has low cost and remarkable comprehensive economic benefit.
