Description

The invention relates to the food industry, in particular to methods for smoking liquid or pasty products, and can be used in the food industry in the manufacture of original sauces with a flavor of smoke.

A known installation for producing a smoking preparation VNIRO [Technology of fish and fish products: Textbook for universities. / V.V. Baranov, I.E. Brazhnaya, V. A. Grokhovsky, etc. / Ed. A.M. Ershova. - SPb .: GIORD, 2006. - 344 p.], Including the cyclone body, recirculation pump, level meter, nozzles, device for maintaining a constant liquid level in the apparatus.

The disadvantage of this installation is the length of the smoking process and the unreliability of the nozzles when working with liquid or pasty products.

The closest in technical essence and the achieved effect is a centrifugal spray for drying solutions [RF patent No. 877266, CL F26B 3/12, B05B 3/12, publ. in B.I. No. 40, 1981], comprising a cylindrical chamber with a cone-shaped bottom, the top of which is connected by a pipe to the finished product collector, a cup disk with guide slots mounted on the drive floor shaft, a flue-air outlet pipe, an inlet ejector, the pipe of which is located inside the drive shaft .

The disadvantage of this installation is the inability to use it for electrostatic smoking.

An object of the invention is to provide a highly efficient process of electrostatic smoking of liquid or pasty products, which allows for reliable and intensive saturation of products with smoke components, which increases the shelf life and improves the organoleptic properties of the products.

The technical task of the invention is achieved by the fact that in the installation for processing liquid and pasty food media in an electrostatic field containing a cylindrical chamber with a cone-shaped bottom, the top of which is connected by a pipe to the finished product collector, a cup disk with guide slots, mounted on the drive hollow shaft, a smoke-air outlet pipe mixture, the input ejector with a nozzle placed inside the drive shaft, new is that it is additionally equipped with a chamber with corona electrodes, the output the nozzle of which is connected to the inlet ejector and to a switchgear located in the center of the lower part of the chamber and made in the form of a cascading row of cones, the vertices of which are directed upwards and form concentric slots between them.

The technical result of the invention is to provide a highly efficient process of electrostatic smoking of liquid or pasty products, which allows for reliable and intensive saturation of products with smoke components, increasing the shelf life and improving the organoleptic properties of the products.

Figure 1 shows a diagram of an installation for processing liquid and paste-like food media in an electrostatic field.

Installation for processing liquid and paste-like food media in an electrostatic field contains a cylindrical chamber 1 with a conical bottom 2, the top of which is connected by a pipe 3 with a collection of finished products 4.

In the upper part of the chamber 1 there is a cup disk 5 with guide slots 6, which has a hollow shaft 7, with a drive 8.

In this case, the cavity of the shaft 7 is connected to the outlet pipe of the smoke-air mixture 9.

Inside the hollow shaft 7, an inlet pipe 10 is arranged coaxially with it, connected to the inlet ejector 11, equipped with a funnel for supplying the product 12.

The installation for processing liquid and paste-like food media in an electrostatic field is equipped with a chamber 13 with corona electrodes 14, the outlet pipe of which 15 is connected via a control distributor 16 to the smoke air pipes 17 and 18 with an inlet ejector 11 and with a distribution device 19, which is located in the center of the lower part of the chamber 1 and is made in the form of a cascade row of cones 20, the vertices of which are directed upwards and form concentric slots 21 between themselves.

Installation for processing liquid and pasty food environments in an electrostatic field works as follows.

The smoke-air mixture is fed into the chamber 13, which, passing through the gaps between the corona electrodes 14, is intensively ionized under the influence of an electrostatic field and sent through the pipe 15 and the distributor 16 through pipelines 17 and 18 to the distribution device 19 and the inlet ejector 11, respectively.

At the same time, a liquid or paste-like product is fed into the funnel 12, which is captured by the flow of the smoke-air mixture entering the ejector 11 through the pipe 18 and the resulting air mixture through the inlet pipe 10 is fed into the inner cavity of the cup disk 5.

A liquid or pasty product through the slots 6 is sprayed in the drying volume of the chamber 1, where the material contacts the smoke coming through the pipe 17 and the concentric slots 21 of the switchgear 19.

Smoke smoke substances are deposited on the surface of a finely dispersed product at a temperature of 20 ... 25 ° C. Exhaust smoke is removed from the chamber through the slots 6 of the cup disc 5 and the outlet pipe 9.

A liquid or pasty product settles on the surface of the cones 20 and is collected in a conical bottom 2, from where it is removed by means of a pipe 3 into a collection of finished products 4.

Installation for processing liquid and paste-like food media in an electrostatic field has the following advantages:

- the additional content of the chamber with the corona electrodes allows ionizing the smoke-air mixture, which, when interacting with positively charged particles of the product, provides intensive saturation of their smoke components;

- the use of an ejector allows efficient and uniform mixing of the smoke-air mixture and the product, and also ensures reliable dispersion of the product into the smoking chamber of the installation;

- the use of a switchgear in the center of the lower part of the chamber and its execution in the form of a cascading row of cones, the tops of which are directed upward and forming concentric slots between them, allows uniform washing off of the product particles by the ionized smoke-air mixture;

- the use of a cup disk with guide slots for spraying liquid and pasty food media into the zone of action of the corona electrodes allows you to provide a large interaction surface of the fine particles of the product with the smoke-air mixture, the rapid saturation of their smoke components, as well as partial concentration of the resulting mixture, which leads to an increase in storage time and improving the organoleptic properties of the finished product.
