Abstract

The invention discloses an ultrasonic multi-effect mixer for edible oil, which adopts the design of an upper cavity and a lower cavity, wherein the upper one is a dispersing cavity, and the lower one is a mixing cavity. The mixed solution entering in the dispersing cavity performs radial and axial circulation under the reverse pushing of a stirring blade, and with the influence action of a baffle in the cavity, the treatment effect of dispersing and mixing is completely achieved, and the requirement of micromixing is achieved. The ultrasonic wave generated by an ultrasonic generator arranged in a barrel body can be used for assisting in degumming, when an ultrasonic field passes through a uniform gum dispersion system, gum grains move towards the direction of the crest or the trough of the ultrasonic wave, and then perform breakage and collapse to demulsify, and the cavatition effect of the ultrasonic wave causes the changes of a medium, a substrate, and the generation structure and properties of an enzyme in an enzyme reaction system, and then causes the exposure of the action centre of the enzyme; effective binding between the substrate and the enzyme is promoted, thus improving the catalytic activity of the enzyme; and via the arrangements of multi-stage mixing and the ultrasonic generator, edible crude oil achieves the effect of a high degumming speed.
