The invention relates to agriculture, namely the processing of liquid products such as milk, juices and other agricultural and food industry to ensure its long-term preservation without compromising the nutritional and taste properties.

Known electroactuator A1-PEI-1000, commercially available LLC Akomas", electroactuator for liquid food products (patent No. 2045919), "WORLD", the device for processing liquid radiation in a thin layer (patent No. 2075163).

Disadvantages units A1-PEI-1000 and LLC Akomas" is that the processing liquid product IR-heating does not occur in a thin layer, and in a large volume of fluid flowing inside a quartz tube, which leads to a significant increase in electric power of the heater, and hence more energy.

The drawback of the device for processing liquid radiation in a thin layer (patent No. 2075163) is the difficulty of forming a thin layer of the product while changing the flow rate in the working cylinder, which can cause poor handling of the product of the infrared radiation.

The closest in technical essence of the present invention is electroactuator for liquid food products (patent No. 2045919), "WORLD", contains a section IR-heating, storage tank, pump, regenera the PRS and the cooler, communication of the treated fluid, cooling water and piping included in the treated fluid communication between the exit section of the IR heating and entering the cooler. Section IR-heating is a bundle of quartz tubes with heater, made in the form of high resistance spiral wound on the surface of the tubes and fixed with insulation with reflective inner surface. At the entrance to the section of the IR heating installed pulsator and the swirl flow of the treated fluid.

The disadvantages of the prototype is that the processing liquid product IR-heating does not occur in a thin layer, and in a large volume of fluid flowing inside a quartz tube, which requires high electrical power of the heaters, and consequently, leads to high energy consumption. When performance 1000 l/h installation power is 20 kW. The lack of processing liquid product and technical liquids UV radiation increases the likelihood of bacterial contamination and contamination of the finished product.

The task of the invention is the provision of the necessary quality liquid product that complies with the requirements of GOST, TU, and other standards, reducing energy costs on the process of product, simplicity of equipment.

And h the th installation for processing liquid infrared and ultraviolet radiation in a thin layer is designed to provide long-term preservation without altering the nutritional and taste properties of liquid food products (milk, juices and other) and can be used on dairy farms, workshops and mini-factories for processing agricultural products. In use of the present invention is the opportunity to significantly improve the quality of the processing liquid food product to ensure its long-term preservation without altering its nutritional and taste properties, can reduce energy consumption by 15-20% during the same performance, installation ease of installation of equipment.

The above technical result is achieved by a modular plant for processing liquid infrared and ultraviolet radiation in a thin layer containing the external slave cylinder on which you install the insulation with reflective internal surface of the pipes for supplying and discharging fluid includes one or more with the same design of modules interconnected in series or parallel, or combined by pipeline, and each module contains an internal slave cylinder of quartz glass, is placed coaxially inside the outer working cylinder so that the annular gap between them does not exceed 2 mm, the source of infrared radiation or UV radiation mounted coaxially within the internal cavity of the cylinder.

According to the COI is to cal the thickness of the gap or a layer of the treated fluid choose no more than 2 mm, based on the penetrating ability of the IR or UV emitter.

The invention is illustrated by the drawing, which shows a functional flow chart of operation of the plant for processing liquid infrared and ultraviolet radiation in a thin layer.

Installation for processing liquid infrared and ultrafioletowymi radiation of a thin layer includes a number of modules 1, which can be integrated into existing manufacturing lines for the processing of liquid food and contains connections for inlet 2 and drain 3, on which are mounted the inner 4 and outer 5 working cylinders, so that the gap between them does not exceed 2 mm, the source of infrared radiation 6 or the source of UV radiation 7, is inserted into the internal cavity of the working cylinder 4, on the outside of the working cylinder 5 is mounted in the insulation 8, having a reflective inner surface 9.

Works as a modular unit for processing liquid infrared and ultraviolet radiation in a thin layer as follows. Liquid food product under pressure through the supply pipe 2 is fed into the inner volume of the working chamber between the inner 4 and outer 5 working rolls. Leaking internal volume of the product is exposed to from the source of infrared radiation 6 or UV radiation 7, which is in the cavity interior is of alindra 5. Short contactless impact IR high density leads to rapid heating of the product and, if the module contains a UV radiation source, is the sterilization of the entire layer thickness of the flowing fluid (including technical), and through the pipe outlet 3 product arrives in the next module or to issue, for example, in the receiving tank.

Installation for processing a thin liquid layer of infrared or ultraviolet radiation, containing a source of infrared or ultraviolet radiation, pipes for supplying and discharging fluid, characterized in that it is made in the same design modules, interconnected by means of pipes, and each module contains external slave cylinder installed insulation with a reflective inner surface, and the inner working cylinder of quartz glass, is placed coaxially inside the outer of the working cylinder with the formation of the annular gap between them not exceeding 2 mm, with a source of infrared or ultraviolet radiation is installed coaxially in the cavity of the inner working of the cylinder.
