The invention relates to the food industry, in particular to a method for producing aromatic alcohols for beverages from liquid semi-finished infusions and to a plant for its implementation.

The purpose of the invention is to improve the quality of the finished product by increasing the content of aromatic substances in it and saving thermal energy resources.

The method is carried out as follows.

The infusion of a water-alcohol solution with an alcohol and essential oils content provided by a formulation with an alcohol content obtained from a plant or essential oil raw material is divided into two streams in a 1: 2 ratio. A larger stream of tincture with a solvent concentration of 45-60% by volume is evacuated at 20-25 ° C to a pressure of 5.00-10.0 kGTa and held for 3-6 minutes. The smaller flow is heated to boiling point. The larger, oxygen-free stream, is distilled under a residual pressure of 5.0-10.0 kPa, and the heated, smaller stream is continuously injected as feed during the distillation process and undergoes a process under vacuum, forming an additional reflux stream, which section are in two equal parts. One part of the reflux is returned to the distillation cube together with the main reflux stream, and the second part is sent to the finished product during its cooling to 18-20 C.

The condenser 11 is equipped with a coil 51 for condensation of vapors during the evacuation of the chiller with inlet and outlet pipes and is connected by a pipe 52 to a vacuum pump 12.

The installation works as follows.

The aqueous-alcoholic solution obtained by one of the known methods is fed separately to the unit. The first STREAM with a concentration of 45-60 vol.% Through fitting 17 through conduit 18 | And 19 is supplied to float dispenser 3, 5 of which flows through conduit 22 to distillation cube 4. Filling is carried out at 65-70% by volume | with the valve closed 15 and. They stop reaching the level limited by the regulator 20, and the infusion with a concentration up to 80 vol.% Through nozzle 13 is fed into the collection of infusions 1, controlling the flow through the level gauge 14. After filling the infusions, the valve 15 opens and informs the collection 1 and distillation cube 4, water is supplied for cooling to the dephlegmator 5, cond nsatory 7 and 11, the collection receptacle 10, the vacuum pump 12, the pressure is reduced to 5,00-10,0 kPa and maintained for 3-6 minutes to remove dissolved oxygen from the present (reduce oxidation processes that contribute to the formation of aldehydes). After the degassing process is completed, heat carrier is supplied to the steam jacket 24 of the distillation cube 4 and the infusion is gradually heated in the distillation cube 4 and heat exchanger 2 to 40-45 ° C, boiling it in the distillation cube at a pressure of 5-10 kPa. Vigorously formed vapors through the mesh insert 30 enter the cavity of the helmet 31, where the selection of high-boiling components begins and their return to the boiling zone of the infusion, and the bulk of the vapor enters the trunk.32 into the two-stage reflux condenser 5, where the processes forming the final product, by selectively two-stage selection of impurities at the boiling point. Coming into a horizontally placed coil end

The sensor 33 alcohol vapors, moving in a spiral, get rid of high-boiling components. Condensate, which forms within the causal coil, flows over its surface and through the connecting tubes simultaneously enters the collector 35, from which the pipeline with a hydraulic seal

36 returns to the distillation cube 4 and to the collector 37, from which flows into the lantern biv a certain ratio flows in two streams, one of which flows through pipelines 38

and the seal 36 is returned to the distillation cube 4, and the second flow through conduit 40 is directed along with the pairs to the coil 41 of the condenser 7, and the control of the refrigerant flowing into the reflux condenser 5 is controlled by the flow meter 42. The condensate entering the distribution 8 is partially flows into the sampler 9 and at the same time through the pipeline 43 into one of the chambers of the collector 10, formed by the dividing wall 44, through the tubular drain 45 or 46. The coil 47 mounted into the first chamber is designed to pre-cool the resulting product, which Erez pipe 48, and substandard fraction from chamber 11 through the pipe 49 is taken for further use (when fully depressurized installation). The evacuation of the installation is carried out by pumping out the air, which through pipe 50, the coil 51 of the condenser 11, intended for the selection of aromatic substances,

the pipe 52 by the vacuum pump 12 is retracted from the installation. The lowering of the present in the cube 4, resulting from the distillation and selection of the finished product, is compensated by the supply

level stabilization in the cube 4 and concentration of substances selected in the pro51

To normalize the level of the environment

These and flow of the vapor phase distillation cube 4 and float dispenser 3 are communicated by pipeline 21.

With the appearance of samples taken from the sampler, extraneous ojsra-nolptic sensations, the selection of aromatic alcohols into the food chamber 1 of collection 10 is stopped, and the floor

Subjected to non-conditioned aromatic alcohol, through a tubular perforated drain 46 is poured into a condenser 11, the pressure throughout the installation is increased to normal (atmospheric) and distillation is continued until the end (tail) fractions are obtained, and then the distillation is completed until the alcohol content is distilled to zero. After that, the flow of coolant and cold water is turned off, the distillation residue is drained through pipe 27 into the sewage system, and the installation is washed with hot water and steamed with hot steam.

Example 1. For the production of aromatic alcohol, lemon-rind (fresh) is used as the aromatic raw material. The method is carried out on a distillation apparatus with a capacity of the distillation cube 140 l. 30 kg of raw materials are drawn twice every 5 days with a water-alcohol solution with a strength of 90 vol.% And 45 vol .; for obtaining the infusion of the first and second gulf. After blending, 150 liters of infusion was obtained.

The resulting solution is divided into two streams in a 1: 2 ratio, with a larger flow of 100 liters evacuating with a residual pressure of 10 kPa to remove dissolved oxygen, and then carry out

Distillation at a residual pressure of 10 kPa and a temperature of 45 ° C. A smaller flow of 50 liters is heated to 42 ° C and introduced continuously into a larger flow during the distillation process with a specific speed (average) of 0.108 l / h.

In the process of distillation, an additional reflux stream is formed, which is divided into two equal parts, one of which is returned in the distillation process by the joint main stream of reflux, and the second is sent to the finished product, which together with this reflux is cooled to 18 ° C. is shown in table 1.

Example

The process is conducted

as in example 1, only before distillation the infusion is divided into two streams with a ratio of 1: 2.8. As a result, the quality of the product has improved somewhat, but the losses have increased, since a smaller amount of infusion is fed to the feed.

Example The process is carried out analogously to example 1, only before the distillation the infusion is divided into two streams with a ratio of 0.9 - 1. As a result, the quality of the product has deteriorated, since it is painful to feed.

more than a distillation. The concentration of the essential oil has decreased by 36%.

If streams are divided in the ratio of 1; 1, then the quality of the product obtained also remains low, which is reflected in Example 4 ...

Thus, only this ratio of flows, i.e. 1: 2 is optimal for achieving the goal.

Table 2 presents the yield of aromatic alcohols upon receipt by a known method.

Table 3 shows the comparative indicators of the method and installation upon receipt of aromatic alcohols on the proposed and known methods.

Thus, the use of the proposed invention allows to reach the concentration of essential oil 2 times higher than in the known method, and to reduce heat and energy consumption.
