Abstract

An apparatus and method for the emulsification of fluids. Mixing of the fluids may occur before the fluids enter the apparatus, or in the apparatus. Extremely low pressure is created and maintained in an apparatus chamber by accelerating the flow velocity of at least one fluid as flow occurs from a larger to a smaller diameter passageway. Vapors of the fluids to be emulsified mix in said low pressure passageway, which may be a venturi tube. When the mixed vapors flow from the smaller diameter passageway to a second larger diameter outlet passageway, deceleration results in a pressure increase which causes the mixed vapors to collapse into the emulsified products. A single emulsification in the apparatus produces emulsified particles with diameters in the range of 0.01 to 2 microns. The apparatus is capable of homogenizing milk, emulsifying fuel and water, emulsifying solutions with immiscible fluids, and producing other regular or thixotropic emulsions.
