RU2440408C1 - Essential oil distillation plant - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: essential oil distillation plant comprises tight steam boiler with boiling kettle communicated by steam duct with cooler and separating flask. To intensify distillation and increase process efficiency, said boiling kettle is furnished with a set of grated cartridges arranged there inside. Said boiler has steam chamber made at its bottom communicated with tapered perforated hollow rods and branch pipes to allow steam inside cartridges. Said tapered hollow rods and branch pipes feed steam to cartridges and guide them in mounting into boiling kettle. Boiling kettle center section accommodates perforated essential oil vapors collector. Aforesaid cartridge is provided with tapered steam distributor with ring arranged atop and discharge loop at cartridge bottom.

EFFECT: higher efficiency and simplified design.

Description

The invention relates to equipment for the essential oil industry and can be used in the processing of coniferous herbs, in particular fir green.

A known installation for processing fir greens containing a steam boiler, a loading tank, a cooler and a separator, a loading tank is installed on a steam boiler, and the cooler has a tank for accommodating fir extract from the loading tank, and this tank is made with the possibility of heating by steam coming from loading capacity, the cooler is connected to the steam boiler through a pipe for feeding the latter with hot water (RF patent No. 2135556, C11B 9/02).

The disadvantage of this installation is the design complexity and low productivity.

There is also known a plant for processing green fir, selected as a prototype, containing a sealed container, a steam boiler, steam pipelines, a refrigerator and Florentine, the sealed container has a common wall with a steam generator containing a furnace installed inside, the pipe of which is located in the steam heater, and the steam generator is connected to the steam distributor made in the form of equidistant steam conducting rods with holes evenly spaced along the entire length (RF patent No. 2236442, C11B 9/02).

The disadvantages of this installation are the design complexity, low product quality and the complexity of the “loading-unloading" of coniferous greens.

The objective of the invention is to increase productivity and simplify the design.

The specified technical result in the implementation of the invention, in contrast to the prototype, is achieved by the fact that in the installation for distillation of essential oil containing a sealed steam boiler with a cooking boiler, communicated steam line with a cooler and Florentine, in order to intensify the process of distillation of essential oil and the mechanization of the work "download “unloading” of coniferous greens, the digester is equipped with a set of trellised cassettes placed inside it, and the digester has a steam cavity at the bottom connected to conical hollow pins and a pipe with holes on the entire surface through which steam enters the cassettes, the cone-shaped hollow pins and nozzles being the steam supply and guiding cassettes when they are installed in the digester, and through the cone-shaped nozzle the steam enters the steam distributor located in the cassette and having a ring on top for removing the cassette from the digester, and at the bottom of the cassette has a loop for unloading it.

Figure 1 shows the installation for the distillation of essential oils, a longitudinal section; figure 2 is a section aa in figure 1.

The plant for processing green fir includes a steam boiler 1, filled with water 2 and installed on the furnace 3. In the upper part of the steam boiler 1 is rigidly connected to the steam cavity 4 of the housing 5, made in the form of a cylinder and having a sealing cover 6 with a collector 7, a steam line 8. A collection of 7 vapors of essential oil with holes over its entire surface is placed in the center of the digester 5 over its entire height and collects water vapor with particles of the essential oil. Cone-shaped pins 9 and nozzles 10 are installed in the lower part of the digester 5, where a steam cavity 4 is placed for the steam to enter green fir 11. Through holes are made over the entire surface of the pins 9, nozzles 10 and steam distributors 12. The steam distributor 12 installed in the cassette 14 is provided with a ring 13 for removing the cassette 14 from the digester 5, the cassette 14 having an unloading loop 15 in the lower part for unloading the spent fir green 11. The collector 7 is connected to the refrigerator 16 through a connection 18 and a steam line 8, which is connected by a pipeline to Florentina 17. Cassettes 14 with coniferous herbs 11 are installed on the pins 9 and the nozzles 10.

Installation for processing greenery of fir works as follows.

Water 2 is poured into the steam boiler 1 and installed on the furnace 3. Cassettes 14 with fir green 11 are inserted into the digester body 5, the housing 5 is hermetically closed by a cover 6 with a collector 7. The furnace 3 heats the water 2 in the steam boiler 1 until steam is formed. The steam from the steam boiler 1 enters the steam cavity 4, then into the pins 9, the nozzles 10, the steam distributors 12 and then is distributed through the holes, heating the entire mass of raw materials 11 located in the cassettes 14 of the digester 5. The resulting water vapor particles The essential oil enters through the openings in the collector 7 and moves up, then through the connection 18 and the steam line 8 enter the refrigerator 16, where they condense. The resulting distillate of water and oil flows from the refrigerator 16 through a pipeline to Florentine 17. Here it is divided into raw oil and Florentine water.

Improving the performance and improving the quality of the distillation of essential oil vapors is achieved by intensifying the process of steam treatment of fir greens with hot water vapor, which is mixed with particles of essential oil, dragging them along in the refrigerator and then to Florentine, where the condensate is separated into raw oil and Florentine water .

The implementation of the digester with a set of cassettes makes it possible to mechanize its “loading-unloading” with fir greens, and the establishment of a collection of essential oil vapors and hollow pin guides, pipes and steam distributors through which steam intensively processes fir greens, increases the productivity of the installation.

A plant for processing green fir can be easily implemented in the oil industry.
