Abstract

 A device for processing liquid media containing an ultrasonic vibrations emitter connected to an ultrasonic vibrations generator, housed in a housing, a reaction chamber with a solid partition for the flow of a liquid product, characterized in that the solid partition is made in the form of a box, round, or square, or rectangular, or oval in cross section, with faces parallel to the planes of the emitter of ultrasonic vibrations.

Description

The utility model relates to devices for emulsification and dispersion used in the preparation of finely dispersed emulsions and suspensions in the food, chemical, pharmaceutical and other industries.

Known ultrasonic dispersant containing a working chamber with a removable partition with perforation / 1 /. Ultrasonic transducers are located on one or several faces of the working chamber. The disadvantage of this dispersant is low productivity, insufficient emulsification and dispersion of liquid products.

It is also known a device for water treatment, containing a working chamber in the form of a parallelepiped with inlet and outlet pipes, on the side faces of which are mounted flat ultrasonic transducers and a mechanism for supplying water to the working chamber under pressure / 2 /. The disadvantage of this device is also the low processing efficiency.

Also known is an ultrasonic installation for processing liquid media, in which there is an ultrasonic frequency generator, an ultrasonic transducer / 3 /. The reactor vessel is made tubular, the connections are conical, threaded-end parts of the tubular vessel. The disadvantage of this installation is the low productivity and the inability to process liquid media chemically interacting with the material of the ultrasonic transducer or reactor vessel.

The closest in technical essence is a disperser-mixer, comprising a housing with inlet and outlet nozzles, an ultrasonic oscillator, an ultrasound generator, a solid partition with a curved concave surface to ensure the movement of the liquid mixture in the channel / 4 /. The disadvantage of this dispersant is the relatively low quality of the liquid processing and the inability to process liquid media chemically interacting with the material of the housing or transducer of ultrasonic vibrations.

The objective of the utility model is to increase the productivity of the processed liquid medium, as well as the ability to process liquids chemically interacting with the material of the device casing or transducer of ultrasonic vibrations.

This is achieved by the fact that the device for processing liquid media contains an emitter of ultrasonic vibrations, which is connected to a generator of ultrasonic vibrations. The emitter is in a housing in which a reaction chamber with a solid baffle is placed for the flow of a liquid product. The solid partition is made in the form of a box, round or square or rectangular or oval in cross section, with faces located parallel to the planes of the ultrasonic vibrations emitter.

Figure 1 shows the design of a device for processing liquid media, where:

1 - housing, 2 and 3 - nozzles for supplying and discharging the processed liquid medium, 4 - reaction chamber with a solid partition, 5 - emitter of ultrasonic vibrations, 6 - nozzles for supplying and discharging water.

The device operates as follows:

The liquid medium is sent to the reaction chamber 4 for processing through pipe 2. Where it is exposed to high-intensity ultrasonic vibrations excited in the liquid medium by the emitter 5, as a result of which the processes of emulsification, dispersion, dissolution are intensified, chemical reactions are accelerated, and so on. The reaction chamber is made of sound conducting material inert to the liquid mixture being treated. To reduce energy loss during the transmission of ultrasonic vibrations from the emitter 5 to the reaction chamber 4, the space between them through the nozzles 6 is filled with water.

An example of a specific implementation:

For homogenization, milk enters. The performance of the dispersant-mixer and the device for processing liquid media is the same and is 5 tons per hour. In both cases, commercially available emitters of ultrasonic vibrations are used, the emitting plates of which are made of non-food stainless steel. Therefore, for processing milk in a dispersant-mixer, it is necessary to replace the material of the emitting plates, which reduces the efficiency of their work. The body of the dispersant-mixer is made of food steel, the body of the device for processing liquid media is made of tool steel, and the reaction chamber is made of food stainless steel. Therefore, for processing milk in a dispersant-mixer, it is necessary to replace the material of the emitting plates, which reduces the efficiency of their work. After ultrasonic treatment of milk, the amount of fat globules with a size of less than 2 microns in the dispersant-mixer was 58%, and in the device for processing liquid media-70%. In addition, after processing the milk, the apparatus must be washed and disinfected. Since the total area of the treated surface in the dispersant is much larger than in the proposed device, it rinses and disinfects much more time, as well as a larger volume of washing and disinfecting solutions.
