Description

The invention relates to the medical, food and perfume industries, in particular to technical means for creating an aerosol, and can be used in inhalation therapy, as well as in the manufacture of perfumes and confectionery.

The known technology of creating an aroma by constructing its composition by setting the ratios and dosage of aromatic substances, as well as by combinational disclosure of aroma.

The known technology is characterized by the fact that the aroma is created by constructing an additive composition of aromatic substances, while liquid aromatic substances are dosed in combination into the capacity of the bottle, mixing aromas in predetermined, experimentally selected, exclusive proportions, and passive, consistent, summarizing disclosure of contrasts of perception of a fantasy aroma is carried out by the strength and saturation of the chord from the base, core and leading notes of the aroma, for example, by the principle of changing combinations of several / not less than three / sound Cove varying heights, audible to human ears as the sound unity (. see Jellinek JS Perfume - Dream in a bottle: the composition and operation, selection and use of flavors, translated from German, Moscow, in 1996 - 163...).

The disadvantages of the known solutions are the high complexity and high consumption of aromatic substances.

The closest technical solution to the present invention is the device described in German patent No. 4305277, class. IPC A61M 11/00, publ. 08/25/1994. The known device for generating aerosol contains a high pressure circuit with gas flow controllers connected to a control device, a low pressure outlet circuit ending with an outlet pipe, and a mixing manifold equipped with at least two cartridges with inlet and outlet pipes.

The disadvantages of the known devices are low productivity and operating efficiency of the device due to the complexity of its operation.

The objective of the present invention is to remedy the above disadvantages.

The technical result consists in high productivity and efficiency of the device, as well as in the simplicity of its operation.

The technical result is ensured by the fact that the device for generating an aerosol includes a high pressure circuit with pressure and gas flow regulators, a low pressure bypass circuit ending with an outlet pipe and containing a piping system and a mixing manifold connected to at least two cartridges equipped with an intake and exhaust system tubes. In this case, the cartridges provide the possibility of attaching individual containers to them with substances and / or their solutions in the form of a liquid, sparging of these substances and / or their solutions with gas from the high pressure circuit and discharge of the aerosol into the mixing manifold. The device additionally includes an automated workstation containing a monitor and a computer connected through a control unit to regulators of the flow of gas supplied to the bubbler in separate containers, and the system of inlet and outlet pipes is made on the principle of "pipe in pipe". In this case, the inlet pipe is placed in the exhaust pipe and is protruding from it and entering the liquid located in each individual container, and the end of the exhaust pipe is arranged to be located above the level of the liquid located in each individual container.

Gas pressure regulators are made with built-in pressure gauges.

At the entrances to the mixing aerosol mixing manifold, shutoff valves are installed from each tank.

The collector further comprises a thermocouple.

A high pressure circuit should be understood as a combination of pipelines and shut-off and control valves, which ensure transportation of the medium through it in a gaseous state under a pressure of about 2 atm.

Under the low-pressure discharge circuit should be understood as a combination of pipelines and a mixing manifold, providing transportation of the medium in the form of an aerosol in a state under pressure of about 0 atm.

The technical essence of the present invention is illustrated by the following illustrations.

Figure 1 - General view of the device;

Figure 2 is a longitudinal section of a collector with cartridges;

Figure 3 is a cross section of the collector.

A device for the production of a mixture of aromatic substances includes an automated workstation containing a monitor and a computer, a control unit 1, a low-pressure discharge circuit, a high-pressure circuit containing gas pressure regulators 2, 3, gas flow regulators 4, a mixing manifold 5 and separate containers 6 s substances and / or their solutions in a liquid state. In this case, the mixing manifold 5 is an element of the low-pressure discharge circuit, and is made with an outlet branch pipe 7 attached to it. In addition, it is connected to cartridges 8, which make it possible to attach separate containers 6 with substances and / or their solutions to them, bubble the substances with gas from a high-pressure circuit and the discharge of a gas (aerosol) saturated with a substance into the mixing manifold 5. The cartridges 8 have a system of inlet and outlet pipes made according to the “pipe in pipe” principle. In this case, the exhaust pipe 9 is a pipe that allows the gas saturated with the substance or its solution to be removed from a separate container 6 to the collector 5. The inlet pipe 10 is a pipe that provides a gas supply for bubbling liquid. The inlet pipe 10 is placed in the exhaust pipe 9, and made protruding from it and entering the liquid located in each individual container 6. The end of the exhaust pipe 9 is arranged to be located above the level of the liquid located in each individual container 6. In addition, the tubes supplying aerosol to the collector 5 from each tank 6 are equipped with shutoff valves in the form of valves installed in parallel 11. This provides various compositions with the inclusion and exclusion of individual components. The collector 5 also contains a thermocouple 12, providing the introduction of correction factors in order to reproduce the composition in liquid form. The device may also be equipped with an atmospheric pressure sensor (not shown).

The operation of this device is disclosed by the example of the generation of an aerosol consisting of a mixture of aromatic substances.

Air from the compressor or inert gas from the high pressure cylinder is supplied to the high pressure circuit. The flow rate of the supplied air or gas is controlled by gas pressure regulators 2, 3 and gas flow regulators 4. The pressure value is monitored and determined using pressure gauges built into the pressure regulators 2 and 3. Air or gas enters through the inlet pipe 10 into the containers 6 fixed in the cartridges 8 for sparging the fragrant substance or its solution. It should be noted that almost all fragrant substances under normal conditions are in a liquid state. Since aromatic substances are very concentrated, to reduce their dominance in the mixture, in some containers 6 before starting the operation of the device, it is not the aromatic substance itself that is placed, but its solution. The use of alternative features ensures the achievement of the same technical result, since when bubbling the gas provides the removal of the molecules of the aromatic substance from the container 6 containing the aromatic substance or its solution.

When bubbling, mass transfer processes are intensified, which ensure the transition of fragrant molecules into the gas phase. Further, the gas saturated with aromatic substances from each tank 6 through the exhaust pipes 9 enters the mixing manifold 5, the aromatic substances are mixed, and the resulting mixture is discharged through the outlet pipe 7. The mixture is discharged by supplying air or gas from the low pressure circuit to the mixing manifold 5 through a regulator gas pressure 3.

The specialist analyzes the resulting mixture through the sense of smell. The specialist carries out the adjustment of the proportions of aromatic substances in the mixture using a computer, an automated workstation. Through the control unit 1 connected to the computer, the gas flow controllers 4 (solenoid valves installed in parallel) are exposed to provide a change in the flow rate of air or inert gas supplied to the bubbler to a specific container 6 with the aromatic substance and / or its solution.
