Latest company news about Ultrasonic emulsifying device for biodiesel processing

  Ultrasonic emulsification is a process in which two or more immiscible liquids are mixed together under the action of ultrasonic energy, and one of the liquids is uniformly dispersed in the other to form an emulsion liquid. Ultrasonic emulsification is an application of ultrasonic technology in liquid treatment. Compared with traditional emulsification methods, its biggest feature is that it does not require emulsifiers.

  Biodiesel is a type of diesel fuel derived from plants or animals, consisting of long-chain fatty acid esters. It's usually made by chemically reacting a lipid, such as animal fat (tallow), soybean oil, or some other vegetable oil, with an alcohol to make a methyl, ethyl, or propyl ester.
  Traditional biodiesel production equipment can only be processed in batches, resulting in very low production efficiency. Due to the addition of many emulsifiers, the yield and quality of biodiesel are relatively low. Ultrasonic biodiesel emulsification equipment can realize continuous on-line processing, and the production efficiency can be increased by 200-400 times. At the same time, ultra-high ultrasonic power can reduce the use of emulsifiers. The oil yield of biodiesel produced in this way is as high as 95-99%. The quality of the oil is also greatly improved.

Preparation steps of biodiesel:
1. Mix vegetable oil or animal fat with methanol or Z alcohol and sodium methoxide or sodium hydroxide.
2. Heating the mixed solution by electric heating to 45-65 degrees Celsius.
3. Ultrasonic treatment of the heated mixed liquid.
4. Glycerin is separated using a centrifuge to obtain biodiesel.
