What factors influence the results of vacuum emulsifier emulsification?

Factors affecting the results ofvacuum emulsifieremulsification are the following1, the form of the vacuum emulsifier (batch and continuous) (continuous than batch better)2, the shear rate of the emulsified head (bigger, the better the effect) 3, the toothstructure of the emulsifier (divided into the first teeth, medium teeth, fine teeth, ultra-fine teeth, about fine teeth effect the better)The length of the wall stay, the emulsification dispersion time (can be regarded as the same motor, the smaller the flow, the better the effect)5,the number of times the vacuum emulsifiercycle (more, the better the effect, to the duration of the equipment, it can not be better)vacuum emulsifier temperature on emulsification is good or bad, but there is no strict limit on temperature, such as oil, water is liquid, you can be stirred at room temperature to achieve emulsificationThe general emulsified temperature depends on the melting point of the high melting point substance contained in the two phases, and also considers factors such as the type of emulsifier and the solubility of the oil phase and the water phaseIn addition, the temperature of the two phases should be kept nearly the same, especially for wax and fat phase components containing a highmelting point (above 70 degrees C), when emulsifying, the water phase of low temperature cannot be added to prevent wax and fat crystallization before emulsification, resulting in blocky or rough uneven emulsionsGenerally speaking, when emulsifying, the temperature of oil and water can be controlled between 75 degrees C-85 degrees C, such as the oil phase has a high melting point of wax and other components, then the emulsification temperature will be higherIn addition, in the emulsification process such as the viscosity increased greatly, so-called too thick and affect stirring, can appropriately raise some emulsification temperatureIf the emulsifier used has a certain phase-shifting temperature, then the emulsified temperature is also selected in the transition temperatureEmulsified temperatures sometimes have an effect on the size of emulsion particlesAs is the case with fatty acid soap anion emulsifier, when emulsified with primary soap, the emulsion temperature is controlled at 80 degrees C, the size of the emulsion particles is about 1.8-2.0 m, if emulsified at 60 degrees C, the particle size is about 6 ?mWhen emulsified with non-ionized emulsifiers, the emulsified temperature had a weak influence on particle sizevacuum emulsifier time
vacuum emulsifier emulsification time obviously has an impact on the quality of the emulsion, and emulsification time is determined according to the volume ratio of the oil phase, the viscosity of the two phases and the viscosity of the emulsion, the type and dosage of the emulsifier, and the emulsification temperature, but the amount of emulsification time is to make the system is closely connected with the emulsionIf emulsifying with a homogenizer (3000 rpm), it only takes 3-10 minutesvacuum emulsifiermixing speed
vacuum emulsifier emulsification equipment has a great influence on emulsification, one of which is the effect of mixing speed on emulsificationThe moderate stirring speed is to make the oil phase and water fully mixed, stirring speed is too low, obviously can not achieve the purpose of full mixing, but the stirring speed is too high, will bring bubbles into the system, making it a three-phase system, and make the emulsion unstableTherefore, the stirring must avoid the entry of air, vacuum emulsifier has a very superior performancevacuum emulsifierselect(1) vacuum emulsifier seispellents that are similar to emulsified substances;(2) select several emulsifier solder mixtures,(3) choose soluble emulsifiers,(4) vacuum emulsifiers and better hydrophilic emulsifiers mixed; (5) Using the same hydrophobic compound emulsifier made from the same hydrophobic raw material, (6) the preparation of O/W-like liquid to water-soluble emulsifier-based, the remaining emulsifier in order of HLB on both sides of the main emulsifier decreased, (7) vacuum emulsifier compound emulsifier HLB value should be roughly the same as the emulsion oily substance;
