Emulsifying mixing machine is a kind of equipment that could dissolve water and fat. Under normal circumstance water and fat could not be mixed. But if external force is involved, things become different. The theory of emulsification equipment is that under the centrifugal force generated by the high speed of rotor, the materials (water and fat) are sheared, mixed, squeezed, dispersed and homogenized in the narrow clearance of stator and rotor so as to form suspension, emulsion and foam. With the help of emulgator and frequent cycling stirring, the emulsion finally be homogenized mixed, and we get stable product with high quality. This machine and theory is widely applied to industrial manufacture, especially in the field of cosmetic, food, chemical, pharmacy, petroleum, paint coating, etc.
High shear emulsifier has played a significant role in industrial stirring and mixing procedure, including stirring solid with liquid, liquid with liquid. In order to achieve good effect of emulsifying, following 4 factors should be seriously considered.
Worked as intermediary between water and fat, emulgator has played an indispensable role to emulsify water and fat under the effect of electronic and molecule. The type and the dosage of emulgator have worked to decide how long the emulsion could be reserved. 1%, 5% and 10% concentration of emulgator undoubtedly has different degree function during the stirring.
- Stirring Rate.
Besides emulgator, stirring rate is also a crucial role during emulsion process. Needless to say, the quicker speed of stirring, the stronger power will be made on materials. Intense pressure forces water and fat be dispersed and shattered into smaller and smaller granule. Then under the help of emulgator and strong external pressure, smaller granules will be gathered and homogenized mixed once again. Fine and smooth emulsion need quick rotation of stator to make the molecule smaller. It is worth mentioning that too quick stirring will also bring some air bubble in the emulsion, which will definitely influence the quality of emulsion. Controlling the rate of stirring is a key way to control the quality of emulsion.
Generally speaking, emulsifying temperature relies on the higher one melting point of the two materials and solubility between water and fat. When the oil and water is liquid, we could mix them under room temperature, because the temperature of oil and water is approximate. As for some special oil with high melting point(higher than 70°C), like wax and tallow oil, we could not immediately put water into oil due to their big gap of temperature, in order to avoid crystallizing wax and fatty before emulsifying. It is better to control the temperature of oil and water between 75°C and 85°C, and also a higher emulsifying temperature with a higher melting point oil.
- Time of emulsifying
The time of emulsifying could decide the quality of emulsion. Volumetric ratio of water and oil, the viscosity, type of emulgator and dosage, and temperature of emulsifying are some of the factors to influence the time of emulsifying. For example, utilize a high shear emulsifier with 3000 rpm, and 3-10 minutes is enough to achieve the effect. In addition, we could control the time according to our specific requirement.
