Description

The utility model relates to the food industry, namely, dispersion and mixing devices used to mix the flows of liquid food mixtures, for example, in the manufacture of dairy products, ice cream, a variety of drinks, syrups, etc.

State of the art

A known analogue to the utility model of the Russian Federation 50431 U1, B28C 5/46, publ. 2006, a hydrodynamic dispersant containing a housing with sockets, a channel for moving the liquid food mixture, devices that cause cavitation when flowing around the liquid food mixture. In its channel for the movement of the liquid food mixture, at least one partition is located to separate the flow of the liquid food mixture, and transverse corrugations or alternating protrusions and depressions are located on the surface of the partition in contact with the flow of the liquid food mixture, due to which liquid flows around cavitation. It is close in design features, but there is no ultrasonic emitter.

The prototype of the claimed utility model is a disperser-mixer with an emitter of ultrasonic vibrations, containing a sealed container in the form of a housing with a lid, a loading nozzle with a tap, an outlet nozzle, fittings for supplying and removing coolant, known from the source - SU 1803324 A, D28C 5 / 46, 1993

The disadvantages of this prototype include:

firstly, the high complexity when using it,

secondly, a sufficiently large time dispersion of the liquid food mixture,

and finally, the unreliability of the design.

Utility Model Essence

The technical result of the claimed utility model is aimed at reducing the complexity when using it and the time of dispersion of the liquid food mixture, as well as at creating a reliable design of the dispersant-mixer.

The above technical result is achieved by the fact that at least one additionally introduced at least one ultrasonic oscillator connected to the ultrasonic oscillator and placed in the housing is inserted into the disperser-mixer, comprising a housing with inlet and outlet nozzles, and a solid partition with at least one curved concave surface facing the surface of the ultrasonic oscillator, wherein the partition is placed in the housing with the possibility of formation from the surface styami housing walls and the surface of the emitter, at least one channel for movement of the liquid mixture from the inlet to the outlet nozzle.

An additional technical result is an increase in the intensity of dispersion and mixing can be obtained in special cases of the dispersant.

The dispersant-mixer can be made with a second emitter of ultrasonic vibrations, and on a solid partition a second concave curved surface can be made, facing the surface of the second emitter of ultrasonic vibrations.

The cross section of the housing with a plane perpendicular to the direction of movement of the liquid mixture of the dispersant-mixer can be a polygon.

The essence of the proposed technical solution is illustrated by the graphic materials presented below:

Utility Model Implementation

Dispersant - mixer contains a housing (1), a liquid mixture, which is a mixture of various food liquids, or a mixture of liquid with particles of a solid substance, enters the inlet pipe (2) of the case, where in the channel for movement of the liquid mixture is exposed to an ultrasonic field emitted by milk whole cow (50%), cream (18%),

condensed milk with sugar (18%), granulated sugar (8%), cocoa powder (2%), the rest up to 100% is water.

After dispersion, the particle diameter of the mixture decreases by 50-70% compared to the original. In this case, the particles of the liquid mixture are distributed evenly throughout the volume of the mixture, thereby improving the structure of the ice cream.

Based on the foregoing, the introduction of this utility model into production will reduce the complexity of working with the device (dispersant), in addition, it will reduce the time of dispersion of the liquid food mixture and increase the reliability of the design of the dispersant-mixer.

emitter of ultrasonic vibrations (3). The curved concave surface of the solid partition (4) captures ultrasonic waves. The result is a turbulent movement of the flow of the liquid mixture in the channel (5), formed by a partition (4) by the surfaces of the walls of the housing and the emitter (3) (figure 2).

So, there is intensive mixing of the moving liquid mixture. The fluid flow ceases to be laminar and now its fluid particles make unsteady random movements along complex trajectories. Accordingly, the liquid mixture is dispersed and mixed.

And finally, discontinuity occurs inside the fluid of the cavities, i.e. the formation of cavities in a dropping liquid. Thus, the flow of the liquid mixture enters from the channel (5) into the associated outlet pipe (7) already dispersed.

The process described above is called cavitation. Physically, this process is based on the fact that local pressure decreases below critical pressure. The use of ultrasound to create cavitation is widely known in the art.

The claimed dispersant-mixer is intended for grinding a liquid mixture. Dispersion is carried out using ultrasonic vibrations, which increase the intensity of interaction with other substances (solid or liquid particles).

The ultrasonic vibrations generator (6) is connected to one ultrasonic vibrations emitter (3), which increases the intensity of interaction of the liquid mixture with other substances and is housed in the housing (1), or with several ultrasonic vibrators (3), for example, two (Fig. 3 and 4).

The device can also be made with several curved concave surfaces, for example, two (FIGS. 3 and 4) facing the surface of the second emitter (3) for an even greater intensity of dispersion and mixing of the liquid mixture.

In particular, FIG. 4 shows the design of a dispersant-mixer with several channels (5), for example, with a two and with a cross-section of the housing (1) plane perpendicular to the direction of movement of the liquid mixture in the form of a polygon, also used to increase the intensity of dispersion and mixing of the liquid mixture.

Consider the operation of a dispersant-mixer, in the case of application in the production of ice cream using the following food mixture as an example:

The composition of the liquid mixture

whole cow's milk (50%),

cream (18%),

condensed milk with sugar (18%),

granulated sugar (8%),

cocoa powder (2%),

the rest up to 100% is water.

After dispersion, the particle diameter of the mixture decreases by 50-70% compared to the original. In this case, the particles of the liquid mixture are distributed evenly throughout the volume of the mixture, thereby improving the structure of the ice cream.

Based on the foregoing, the introduction of this utility model into production will reduce the complexity of working with the device (dispersant), in addition, it will reduce the time of dispersion of the liquid food mixture and increase the reliability of the design of the dispersant-mixer
