Ultrasonic Emulsification Technology Application Sharing

Advantages of ultrasonic emulsification compared to traditional mechanical agitation high speed shearing:

1. The emulsion has a fine particle size (the finest can reach 100 nm)

2. The emulsion is not easy to stratify

3. Low energy consumption (1/10-1/20 of mechanical mode) JP600G ultrasonic extraction/emulsification unit, volume 20L, ultrasonic power 1000W, frequency 28KHZ, material SUS304 stainless steel, electric heating power 2000W, digital power can Adjustable digital clock adjustable digital sweep adjustable digital temperature control.

Things to be aware of when users use ultrasound:

Ultrasonic emulsification:

First, the formulation of the emulsion includes the amount of emulsifier.

Second, the choice of emulsification time is not as long as the time is long. The emulsification process is a process of dispersion and polymerization. According to the existing test results, the emulsified particle size of 10-15 minutes can be as small as 100 nm. The most important thing is the choice of digital frequency sweep. There are 16 choices. The lower the value, the thicker the bubble and the stronger the power. The higher the value, the thinner the bubble and the smaller the power. Different extraction or emulsifying substances change the digital sweep to bring different effects and efficiency.

Third, the advantages of ultrasonic emulsification:

1. The emulsion formed by ultrasonic emulsification has a small average droplet size of 0.2 to 2 um; the droplet size distribution range is narrow, and may be 01 to 10 um or less.

2. Ultrasonic milk concentration is high, the concentration of pure emulsion can exceed 30%, and the emulsifier can be up to 70%.

3. The formed emulsion is more stable. An important feature of phacoemulsification is that it can produce an extremely stable emulsion without or with less emulsifier.

4. The type of emulsion can be controlled. Using phacoemulsification, O/W (oil-in-water) and W/O (water-in-oil) emulsions can be prepared under certain sound field conditions; however, it is impossible to use mechanical emulsification, only the nature of the emulsifier. In order to control the type of emulsion.

5. Toluene is emulsified in water, forming one type of emulsion under low sound intensity conditions, and another type of emulsion under high sound intensity conditions.

6. Ultrasonic emulsification requires less power to produce the emulsion.
