Description

The invention relates to devices for the electrical treatment of liquids and can be used to process milk and other dairy products (koumiss, ayran, etc.) by direct electric current to improve the quality of removal of pathogenic microflora, antibiotics, pesticides, disinfectants, toxins, nitrates, nitrides from it heavy elements.

A device is known - an electrical separator for the electrical treatment of liquids, mainly milk, containing a housing with liquid inlet and outlet nozzles, a product distributor over which the main electrodes are mounted, fixed between the upper and lower gratings, and a horizontal partition with mixing vertical pipes installed above the distributor (RU 827110, IPC B01D 17/06 published on 05/07/1981). The disadvantage of this device is the insufficient degree of electrical processing of milk.

The closest analogue, by the presence of essential features, which is adopted as a prototype, is a device for the electrical treatment of liquids, mainly milk, containing a housing with a set of electrodes mounted on top of each other. The electrodes are made in the form of anode and cathode disks with central holes, the housing is made in the form of a truncated cone. Anodes and cathodes are made of different materials. The lower and lateral surface of each anode is covered with a shell with a central hole of electrically insulating material (RU 2043041 C1, IPC A23L 3/32, publ. 09/10/1995). The disadvantage of the prototype is the insufficient degree of electrical processing of milk and other dairy products.

The objective of the proposed technical solution is to increase the degree of electrical processing of milk and dairy products.

The technical result is achieved due to the fact that the device for electric processing of dairy products, contains a housing in which a set of electrodes, nozzles for supplying, draining liquid, draining sediment, source

a current located outside the housing, but, unlike the prototype, the housing is made in the form of a horizontally positioned hollow cylinder with end caps, the housing has a transitional part in front of the liquid outlet pipe, which forms a Venturi tube, inside the cylinder, a separator is sequentially fixed to the liquid supply pipe in the form of a grid and mesh electrodes of preliminary cleaning, connected to a separate current source, while the set of electrodes is made in the form of cylindrical surfaces consisting of an anode and cathode, located coaxially and mounted on two disks opposite each other.

The housing is made in the form of a horizontally positioned hollow cylinder with end caps having a transitional part of a smaller diameter in front of the fluid outlet pipe in the form of a venturi. The Venturi pipe has a narrowing of the diameter in the form of a neck, and then a sharp expansion (V.I. Kalitsun, Fundamentals of Hydraulics M .: Stroyizdat, 1972, p. 47-49). In it, in accordance with the Bernoulli equation, there is an increase in the speed of movement of milk and a decrease in the pressure of the fluid flow, which prevents the formation of "dead" zones in parts of the central and peripheral parts of the body. Thus, this form of execution of the housing provides a uniform passage of dairy products through a set of electrodes without stagnation due to loss of speed in it.

Inside the cylinder body, sequentially attached to the fluid supply pipe are: a separator in the form of a grid - in order to reduce the fluid flow rate by changing the nature of the flow of milk from turbulent to laminar, and mesh pre-treatment electrodes connected to a separate current source for additional electrical processing.

A set of electrodes made in the form of cylindrical surfaces mounted on two disks opposite each other, representing the anode and cathode, and located coaxially, which allows, in view of its length, to create an electric field with a large contact area. At the same time, milk is in the electric field for a longer time, which can significantly increase the degree of electric processing, which contributes to a more complete destruction of various toxins, nitrates, nitrides, heavy metals, etc.

 It is known that various substances hazardous to human health pass from the body of animals into milk. Some of them complicate technological processes in the development of dairy products, reduce their quality and nutritional value. These include: pathogenic microflora, antibiotics, pesticides, disinfectants, toxins, nitrates, nitrides, heavy elements (KK Gorbatova, Chemistry and Physics of Milk and Dairy Products. - St. Petersburg: ed. GIORD, 2012, p.73) .

The present invention by increasing the degree of electrical treatment of the liquid provides a more complete removal of pathogenic microflora and toxic substances.

The drawing shows a diagram of the device.

A device for electric processing of dairy products contains a housing 1, diameter D (section A-A), which houses a set of electrodes 10.11, nozzles for supplying and discharging 3 liquids 3, a drain discharge pipe 15, an electric current source 4 for a set of electrodes placed outside corps. The casing is made in the form of a horizontally positioned hollow cylinder 5 with end caps 6 having a transition part 7 of smaller diameter d (section BB). Inside the cylinder, a separator in the form of a grid 8 is sequentially fixed to the fluid supply pipe, after which mesh pre-cleaning electrodes 9 are additionally installed, connected to a separate current source 14. The set of electrodes is made in the form of cylindrical surfaces consisting of anode 10 and cathode 11, located coaxially and mounted on two opposed to each other discs 12 and 13.

The device operates as follows.

Dairy products are fed through the inlet pipe 2 to the housing 1, then to the separator in the form of a grid 8 and to the mesh electrodes of the preliminary cleaning 9. Additional current sources 14 are turned on (current strength, for example, 0.4 A, voltage 0.6 V) on the mesh electrodes of pre-cleaning 9, an electric field arises. The electric field acts on microflora, antibiotics, pesticides and disinfectants, destroying them.

Next, pre-purified milk products enter the space formed by the set of electrodes, namely between the cylindrical surfaces consisting of the anode 10 and cathode 11, located coaxially and mounted on two disks 12 and 13 opposite to each other, and the electric current source 4 is turned on (current strength, e.g. 1.2 A, voltage 2.4 V), an electric field arises between the anode and cathode. The electric field acts on toxins, nitrates, nitrides, destroying them.

      After passing through a set of electrodes, a stream of dairy products processed by an electric field and free of toxins slows down the movement and enters the throat - transitional part 7, with a smaller diameter d (section B-B). Further passage of the processed dairy products from the space formed by the cylindrical surfaces consisting of the anode 10 and the cathode 11 occurs with the help of the transitional part 7 of a smaller diameter, forming a Venturi tube in shape, which has a narrowing in the form of a neck, and then a sharp expansion. In it, in accordance with the Bernoulli equation, there is an increase in the speed of movement of milk and a decrease in the pressure of the fluid flow, which prevents the formation of "dead" zones in areas of the inner part of the peripheral part of the body. The output of the processed dairy products from the housing occurs through the branch pipe 3, to drain the spent sludge is the drain pipe 15.

      The invention allows for the destruction of pathogenic microflora, antibiotics, pesticides and disinfectants, toxins, nitrates, nitrides that enter the milk from the external environment and the body of animals, although not 100%. In this case, after processing, the nutritional and consumer properties of milk are preserved.
