The invention relates to a device for pasteurization, fluid products, mainly food, and can be used for pasteurization of milk, juice, beer, jelly and pastes.

Famous film infrared pasteurizer fluid product (milk), which is used as a prototype (Washausen, Vffaluv, Sencirow "Film infrared pasteurizer milk", journal of Technology in agriculture", 1991, No. 5)containing the receiving tank line filling and level control, a cylindrical working chamber, mounted vertically, an infrared emitter located coaxially in the chamber, recuperative heat exchanger, the temperature sensor pasteurized product, the feeder fluid product on the inner wall of the upper part of the working chamber containing a cavity, a hole for the entrance of fluid product and outlet throttling land for exit of fluid product on the inner wall of the upper part of the working chamber, the supply line to the fluid product from the receiving tank provided with a hole feeder passing through one of the cavities recuperative heat exchanger and containing a pump, control valve and the filter, the output capacity with a hole for the exit of fluid product and a window provided with the bottom part of the working chamber, the main issue of Mastersound the th product communicated with the outlet of the tank, passing through the second cavity of the regenerative heat exchanger containing a pump and a three-way recirculation valve actuator, the line return of the product in the receiving tank is communicated with the receiving tank and through the recirculation valve to the main issue pasteurized product.

The essential features of the proposed technical solutions, coinciding with the essential features of the prototype are the following: the pasteurizer fluid products includes a cylindrical working chamber, mounted vertically, electric infrared emitter mounted coaxially in the chamber, the output capacity with a hole for the exit of fluid product and a window provided with the bottom part of the working chamber, the temperature sensor pasteurized product and the feeder fluid product on the inner wall of the upper part of the working chamber containing a cavity, a hole for the entrance of fluid product and a throttling area to exit the fluid product into the wall of the working chamber.

Known pasteurizers pasteurization does not provide free flowing products with high viscosity, type of jelly, juices, pastes, because the film thickness of pasteurized fluid product when driving down the walls of the working chamber is not stable welding temperature, is:, therefore, when pasteurization of fluid with high viscosity, their movement will be impeded due to hydraulic losses, and the film thickness is increased, the fluid product with high viscosity will be collected in a separate thick jets that will ensure its swelling with minimal hydraulic losses. Uneven film thickness pasteurized product reduces the efficiency of operation of the pasteurizer, requires an increase in the power of the infrared emitter and leads to overheating of the product flowing with a smaller film thickness.

The proposed technical solution solves the technical problem of providing mode, the stabilized film thickness pasteurized product when draining down the walls of the working chamber and thereby enable effective pasteurization and also products with high viscosity.

To achieve the mentioned technical result in the pasteurizer fluid products containing a cylindrical working chamber, mounted vertically, electric infrared emitter mounted coaxially in the chamber, the output capacity with a hole for the exit of fluid product and a window provided with the bottom part of the working chamber, the temperature sensor pasteurized product and the feeder fluid product at GNC the interior wall of the upper part of the working chamber, containing cavity, the hole for the entrance of fluid product and a throttling area to exit the fluid product into the wall of the working chamber, the working chamber is made with a possibility of rotation relative to the geometric longitudinal axis, with the pasteurizer contains the drive rotation of the working chamber.

In addition, to ensure the possibility of using pasteurizer for pasteurization of products of various viscosity throttling area of the feeder fluid product on the inner wall of the upper part of the working chamber can be made with the possibility of tuning the pasteurized product, which can be implemented, for example by replacing the throttling area. Additionally, to protect the IR emitter from the water drops pasteurized product formed in the first moment of the beginning of the work when the impact of the jet on the wall of the chamber, the outlet throttling section of the feed fluid product can be oriented in the direction of rotation of the working chamber and the working chamber in the upper part can be made with a larger diameter. In addition, the drive rotation of the working chamber may be provided with a speed controller that, by controlling the number of revolutions of the working chamber (and hence the centrifugal force and the film thickness on the walls of the working chamber), will enable sosaku the surface with the desired reduced cross-section of the throttling section of the feeder fluid product on the inner wall of the upper part of the working chamber, to find the specific fluid product mode of operation of the pasteurizer with a maximum flow rate at which the thickness of the fluid film of product on the walls of the working chamber corresponds to the penetration depth of infrared radiation. To exclude the presence of quartz glass in the pasteurized product, in case of destruction of the infrared emitter, the output capacitance can be installed filter.

Distinctive features of the proposed pasteurizer fluid product from the above well-known is the implementation of the working chamber for rotation relative to the geometric longitudinal axis and the presence of actuator rotation of the working chamber, and optionally performing a throttling section of the feeder with adjustable under the pasteurized product, the orientation of the output throttling area in the direction of rotation of the working chamber, the working chamber in the upper part with a larger diameter, the supply of drive rotation of the working chamber by the speed controller, the presence of the filter in the output capacitance that is installed beneath her window.

Due to the presence of these distinctive features in conjunction with the known (specified in the restrictive part of the formula) is achieved by the following technical result is ensured by the slave mode is you pasteurizer with a constant stabilized film thickness pasteurized product when draining down the walls of the working chamber and thereby the possibility of pasteurization and also products with high viscosity. In addition:

- increases the efficiency of pasteurization of fluid products due to the alignment of the film thickness along the perimeter of the working chamber by a centrifugal force;

- removable throttling area provides the opportunity pasteurization same pasteurizer different products, significantly differ in their viscosity;

- the orientation of the output throttling area in the direction of rotation of the working chamber provides a "smooth" fluid supply of the product on the walls of the working chamber, spatter fluid product and improving the working conditions of the infrared emitter;

- implementation of the working chamber with a larger diameter at the top in the area of supply of the fluid product in the case of the formation of droplets during startup or shutdown of the pasteurizer remove them from the zone of pasteurization and an infrared emitter, improving working conditions;

- provides the possibility of increasing the performance of the pasteurizer, which revs up the working chamber, by increasing the centrifugal force, capable of providing uniform runoff layer pasteurized product greater thickness, and hence, to increase the second flow rate;

- in case of emergency destruction of housing infrared emitter performed typically made of quartz glass eliminates the I pieces of shell in the pasteurized product.

In the search for sources of patent and scientific and technical information, the set of indicators proposed pasteurizer free flowing products with a working camera made with the possibility of rotation relative to the geometric longitudinal axis, and installation, contains the drive rotation of the working chamber, is not detected. Thus, the present invention meets the eligibility criterion of "new".

Based on comparative analysis of the proposed technical solutions with the prior art by sources of scientific-technical and patent literature it can be argued that between the set of features, including distinctive, and their functions and achievable goals, there are non-obvious causal relationship. Based on the above we can conclude that the technical solution in the proposed device is not obvious from the prior art, and therefore, meets the eligibility criterion of "inventive step".

The three-way valve 27 is communicated with the drain line 24 and provides one of three positions:

- overlapping message line 22 to the output section 33 and the drain line 24;

message line 22 with a plot issue 33 and the ceiling of its messages with the drain line 24;

message line 22 with the drain line 24 and the ceiling of the message line 22 with a plot issue 33 pasteurized product.

The return line 23 fluid product communicated through the section 28 with the receiving tank 14, and is also communicated through a three-way valve 26 to the main issue 22 fluid product before you installed on its output three-way valve 27. Three way valve 26 provides one of three positions:

overlay messages on highways 21 and 23;

- open the message on highways 21 and 23;

the inauguration of highway 21 and overlapping messages through line 23.

The upper part of the cavity of the receiving tank 14 is in communication with the gas cylinder 34 through line 35 containing valve switch 36 gas supply, a pressure regulator 37 and valve 38 and a pressure gauge (manometer) 39 gas in the tank 34. Magistral the 35 before the pressure regulator 37 is in communication with the compressor 40 through line 41, containing valve 42. The supply line to the 35 gas into the cavity of the tank 14 by the pressure regulator 37 is in communication with the relief valve 43. The valve 36 provides when activated, blocking the road 35 and the message of the gas cavity of the tank 14 with the atmosphere.

Pasteurizer fluid products according to claim 1 of the formula works as follows. The three-way valve 25 is installed in the position for receipt in the receiving tank 14 pasteurized product line refills 19 through section 28, the amount of which in the tank 14 is limited by the level switch 15 fluid product by overlapping line refills 19 three-way valve 25. Before starting the pasteurizer in the work of the adjusting valve 30 is in the open position. Open the valve 38 and the gas (air) excess pressure from the tank 34 through line 35 through the pressure regulator 37 and the valve 36 is supplied to the tank 14, naduva his excessive pressure. At a low viscosity pasteurized product on highway supply 21 may be made under the hydrostatic pressure of fluid product in the tank 14, while the switching valve 36 gas supply is installed in a position overlying the message through line 35 and informing the gas space of the tank 14 with the atmosphere. Run the actuator 11, which spins the working chamber 1 to a predetermined what the head speed (number of revolutions per unit of time). Connects to the source of infrared energy emitter 2, which provides the flow of heat to the inner walls of the working chamber 1. The three-way valve 26 is set to a position opening the flow area highways 21 and 23, and includes a pump 29 and 32, and the fluid product under the action of differential pressure in the tank 14 and the additional differential pressure generated by the pump 29, moves along a line feed 21 fluid product through the adjusting valve 30, a filter 31 and the cavity 17 recuperative heat exchanger 16 into the feeder 7 fluid product through the opening 9 enters the cavity 8 of the device 7, from which through a throttling section 10 comes out in the form of a jet on the inner walls of the rotating working chamber 1. The flow of fluid product through line feeder 21 is defined by a reduced cross-section of the throttling section 10. The stream of fluid product exiting section 10, under the action of centrifugal force from the rotation of the camera 1, is uniformly distributed on its walls and flows down under gravity.

The thickness of the fluid film of product on the walls of the chamber 1 through a specific reduced-section of the throttling section 10 the flow of fluid product corresponds to the depth of penetration of infrared radiation from the emitter 2, which provides heating tech is what product to a temperature of pasteurization during his runoff in the lower part of the working chamber 1. The actuator 11 is selected to provide the necessary centrifugal force to stabilize the film thickness on the walls of the working chamber 1 at stream flowing product down.

However, at the beginning of the pasteurizer is heated walls of the working chamber 1 and the temperature of the fluid product is less than the temperature of pasteurization, so the three-way valve 27 is in position overlying the message line 22 with its output section 33, and through the open valve 26 message through line 23 flowable product of the output capacitor 3 through line 22 under the action of differential pressure generated by the pump 32, through the cavity 18 recuperative heat exchanger 16, flowing through line 23 and section 28, returns to the tank 14.

After the release of the pasteurizer to set the operation mode determined by the readings of the temperature sensor 6 a fluid product, three way valve 26 is set to a position overlying the message through line 23 with the saving message through line 21 and valve 27 is installed in a position that opens the message line 22 with its output section 33, and is issuing pasteurized fluid product to the consumer.

The adjusting valve 30 is provided by adjustment of the flow rate of fluid through the pasteurizer, necessary to compensate for the influence of reschedulement temperature values, the viscosity or density of a fluid product from their average values. To stop the operation of the pasteurizer is the shutdown of the pumps 29 and 32, after which the three-way valves 25, 26 and 27 are set in the initial position, the overlying message on all highways of the pasteurizer, power infrared emitter 2, the actuator 11 are closed and the valves 38 and 42. Stopping the operation of the pasteurizer can be made by the operator from a remote control or automatically, for example, according to commands issued by the level switch 15 fluid product in the receiving tank 14.

The operation of the pasteurizer when it is washing and the sequence of using constituent units similar to his work with the pasteurization of fluid product. The difference is that instead of filling a fluid product into the receiving tank 14 through line 19 three way valve 25 is set to the position reporting line flushing 20 section 28 and the cleaning liquid flows into the tank 14. For draining the washing liquid from the pasteurizer three way valve 27 is set to a position indicating line 22 with the drain line 24.

The operation of the pasteurizer according to claim 2 of the formula is similar to the operation of the pasteurizer according to claim 1 of the formula. Additionally, the presence of removable throttling section 10 of the feeder 7 is flowing what about the product on the inner wall of the upper part of the working chamber 1 allows for pasteurization of fluid product with lower viscosity to install throttling nozzles 10 smaller bore and Vice versa. Thus, it is possible to regulate the flow through the chamber 1 of the pasteurizer fluid product with an initial viscosity in a wide range of values and, therefore, expands the range of free flowing products, pasteurization which is possible with the same design of the pasteurizer.

Pasteurizer fluid products according to claim 3 of the formula is the same as the pasteurizer of claim 1 or claim 2 in fact, due to the direction of the throttling nozzle 10 in the direction of rotation of the working chamber 1, as shown in figure 4, decreases the difference of the velocity of the jet of fluid product and a rotating wall of the working chamber 1 at their touch, which provides a "smooth" the interaction of the jet of fluid product from the inner wall, greatly reducing the splashing of fluid product with the formation of small droplets and mist, polluting infrared emitter 2, increases the duration of operation of the pasteurizer until the next washing. Additionally, by reducing the scattering of thermal radiation into small droplets eliminated their "overheating" above the required temperature pasteurization increases the density of the heat flux of infrared radiation falling on the film of fluid product, and the penetration depth of infrared radiation in the pasteurized product that provides the ability to work is acterization with increased maximum flow of fluid product (better performance).

Pasteurizer fluid products according to claim 4 of the formula is the same as the pasteurizer according to items 1-2 formula, the zone of interaction of the jet of fluid product from the wall of the chamber 1 is removed from the infrared emitter 12 and provides a smoother interaction of the jet with the wall of the chamber 1 due to the larger its radius of curvature, as compared with the device according to claim 3, further increases biprobuvannyu resource pasteurizer and maximum performance. In addition, it is possible to location of exhaust throttling section 10 above the wall of the transition section of the camera 1, when the shutdown of the pasteurizer residual quantity of fluid product flowing without excess pressure from section 10, will not be accelerated to fall down in the gap between the emitter 2 and the wall of the chamber 1, and will go on the wall of its bore section and, further draining down the walls of the chamber 1, will undergo pasteurization.

Pasteurizer fluid products according to claim 5 of the formula is the same as the pasteurizer according to items 1-2 formula. Additionally, the pasteurization of fluid product with increased viscosity or flow rate regulator 12 provides an increase in the number of revolutions of the drive 11 of the rotation of the camera 1, which ensures an increase in the centrifugal force acting on the pasteurized liquid product, Stacey down in the article is the Russia of the camera 1, and due to this alignment of the fluid film thickness product of greater viscosity or more second flow rate. For the same design of the pasteurizer on PP-5 interchangeable throttling section 10 is provided by the selection of an appropriate site 10 and the number of revolutions of the working chamber 1 of the actuator 11 by the controller 12, which allows for different pasteurized products to configure the pasteurizer at the maximum rate, at which the penetration depth of infrared radiation from the emitter 2 in pasteurized product is equal to the thickness of a film on the walls of the chamber 1.

Pasteurizer fluid products according to claim 6 of the formula is the same as the pasteurizer according to items 1-2 formula. Additionally, in the event of an accidental destruction of the hull electric infrared emitter 2 pieces of the case (quartz glass) trapped by the filter 13, the stop operation of the pasteurizer, the replacement of the radiator 2 and the filter 13, and then is provided by the launch and operation of the pasteurizer.
