Description

The invention relates to equipment for the oil and fat industry.

The purpose of the invention is to improve the quality of the emulsion,

Equipping the device with an ultrasonic generator of reciprocating rotor movements in conjunction with the parabolic shape of the rotor itself makes it possible to significantly increase the resistance of the resulting emulsion and reduce the size of the dispersed phase due to the profile of the dispersion zone and the inhibition of processes.

The drawing shows a device for producing emulsions.

The device for producing emulsions, mainly mayonnaise, consists of a housing 1 with connections for supplying the original emulsion 2 and withdrawing the finished emulsion 3. The inlet section 4 of housing I is made in the shape of a truncated cone expanding along the edge.

In case I, a rotor 5 is mounted for rotation and longitudinal reciprocating movement, made in the form of a paraboloid of rotation and facing vertically towards the inlet section 4 of housing I. On the parabolic surface of the rotor 5 and the inner surface of the inlet section 4, the blades 6 are reinforced made of various shapes, and between them form a labyrinth passage for fluid. The rotor shaft 5 is connected to the drive 7 of the rotational motion, as well as to the ultrasonic generator 8 of the reciprocating movements.

The device works as follows.

The coarse emulsion of mayonnaise, obtained in a known manner using mechanical mixing devices, flows through the nozzle 2

in the inlet section 4 of the housing 1, it is processed by alternating blades $ installed on the inner surface of the inlet section 4 and blades 6 mounted on the rotor 5t. For greater mixing efficiency, the blades 6 can be mounted at an angle of 30-45 to the axis,

As a result of the rotation of the rotor 5 from the actuator 7 and the axial vibrations with the ultrasonic frequency excited by the ultrasonic generator 8, the coarse emulsion is intensively mixed and dispersed, the thin emulsion being obtained through the nozzle 3 is removed from the housing 1. If necessary, depending on the viscosity, the specified dispersion, performance and so on, the frequency of rotation of the drive 7 and the frequency of the ultrasonic oscillations of the generator 8 are regulated,

The proposed device allows increasing the resistance of the emulsion (% of fat released) from 1.5% to 1.2-1.3% and ensuring the size of the dispersed phase is less than 2 microns (from 84% to 88-89%). It is streamlined in the form of a paraboloid of rotation the shape of the rotor 5 and conic, expanding the shape of the inlet section 4 provide the minimum hydraulic resistance of the flow part of the device and increase its performance.
