Cavitation device for preparing palm oil-based submicron emulsion

Abstract

The invention provides a cavitation device for preparing a palm oil-based submicron emulsion. The cavitation device comprises a stator, a rotor, ultrasonic transducers and a rotating shaft, wherein the stator is provided with a feeding port, a discharging port and an oxidizing agent conveying pipe, the rotating shaft is installed in the stator, the rotor is arranged in the stator, the rotor is fixedly connected with the rotating shaft, blades are distributed on the rotor, and cavitation holes are distributed in the blades. According to the invention, palm oil is used as a dispersion phase and deionized water is used as a continuous phase to prepare an oil-in-water submicron emulsion; a crude emulsion enters the stator, liquid flow in a stator cavitation cavity is coupled with rotor vibration to achieve a strong cavitation effect; through combination of an ultrasonic probe, hydraulic cavitation and ultrasonic cavitation, cavitation efficiency is improved, energy input is much lower; and thus, the device has great potential in the aspect of emulsion preparation.

Description

technical field [0001] The invention relates to a device for preparing palm oil-based submicron emulsion, in particular to a device for preparing palm oil-based submicron emulsion by using cavitation technology. Background technique [0002] Submicron emulsions can incorporate lipophilic and hydrophilic drugs into the oil phase, increasing their solubility and local bioavailability while minimizing the side effects of effective drugs, so submicron emulsions are used as a treatment for various pain and Colloidal drug carriers on diseases have attracted more and more attention from the medical community. Compared with traditional emulsions, submicron emulsions have higher pharmacological activity and site-specific drug delivery capabilities. Good carrier for drug delivery. [0003] During the emulsification process, extremely high shear force and extremely high energy input are required to break the droplets of the premixed emulsion from micron to submicron or nanoscale, the...
