Description

The invention relates to essential oil production, in particular to equipment for the production of essential oils.

A device for the separation of essential oils (see A.S. No. 138303, class C11B 9/02, 1960) by steam stripping, including a heat-insulated chamber with belt-mounted conveying bodies, loading, unloading and unloading units of material, supply and discharge pipes couple.

This device has several disadvantages. Excessive pressure in the chamber led to large losses of ether-containing steam, and the material, located on the conveyors, was filled with moisture, which made it difficult to isolate the essential oil.

Closest to the proposed device is a device for extracts from citrus fruits (see patent SU 1823880 A3, СВВ 9/02, 1993), including a housing with a container coaxially mounted in it with a drum perforated from a drachel mesh installed in its upper part. A perforated disc is mounted on the drum axis. The housing has loading and unloading devices. The housing is located above the tank having a drain pipe with a tap. The device is equipped with an electric motor for communicating rotational motion to the disk.

The disadvantage of this design is its inability to isolate essential oils from flower-herbaceous raw materials.

An object of the invention is to obtain the possibility of extracting essential oil by distillation using a blow from the seeds, fruits and roots of essential oil plants.

This task is achieved in a device for extracting essential oils from seeds, fruits and roots of essential oil plants, comprising a housing with a lid and a perforated drum coaxially mounted therein, a drive shaft placed coaxially with the perforated drum and the housing. Unlike the prototype, the casing is made in the form of a thermally insulated chamber, the lid of which is thermally insulated and installed tightly, the lid having a nozzle for removing vapors of essential oils, in addition, the bottom of the insulated chamber has nozzles for supplying superheated steam and condensate drain, and a perforated drum rigidly mounted on a shaft located horizontally, and has blades radially located on its cylindrical perforated surface. The presence of a drum with a perforated lateral surface and blades located on its inner part allows to stir up vegetable raw materials, preventing them from caking, thereby reducing the extraction time and increasing the production rate of essential oils.

In addition, overpressure is created inside the chamber, as a result, of supplying superheated steam and to maintain the temperature of the steam and more efficiently release essential oils; The chamber and chamber lid are made insulated and sealed. In addition, the drum is located in a vertical plane and is able to rotate, and on its inner lateral perforated surface there are radially spaced blades that drag the raw materials in the drum into its upper part and dump it there, preventing it from caking, and under the influence of an impact and superheated steam containers of essential oils are destroyed much earlier, which contributes to a more rapid release of essential oils.

The invention is illustrated by drawings, where figure 1 shows a General view of a device for extracting essential oils from seeds, fruits and roots of essential oil plants, and figure 2 is a view aa.

A device for extracting essential oils from seeds, fruits and roots of essential oil plants has a vertically arranged perforated drum and consists of a heat-insulated chamber 1 with a hermetically sealed and heat-insulated lid 2, on the surface of which a pipe 3 is placed, which leads the vapors of essential oils to the distiller; at the bottom of the heat-insulated chamber 1 there are pipes for supplying superheated steam 4 and condensate drainage of intercellular fluid 5; inside the insulated chamber 1 there is a perforated drum 6 with blades 7 mounted radially on its inner perforated side surface, driven into rotational movement by the drive system 8.

A device for extracting essential oils from seeds, fruits and roots of essential oil plants with a vertical arrangement of the drum works as follows: essential oil raw materials are loaded into the drum 6, the lid 2 hermetically seals the insulated chamber 1, overheated steam enters the insulated chamber 1 through the pipe 4, creating there is excess pressure in it, the drive system 8 rotates the drum 6, in which the essential oil raw materials, under the influence of superheated steam, emit vapors of essential oil, and the presence of blades 7, mixing Raw accelerate this process. Water vapor and essential oil vapors are discharged into the condenser by pipe 3, and the condensate is discharged by pipe 5 to the outside.

A device for extracting essential oils from seeds, fruits and roots of essential oil plants allows you to:

- increase the yield of essential oils from essential oil raw materials due to the active tedding of raw materials in the process of processing it with superheated steam;

- increase, if necessary, the duration of the processing of raw materials;

- use the extraction method with volatile solvents to isolate essential oils of the “absolute” type, for which the bypass pipe is suppressed, and the lower part of the chamber is filled with solvent (petroleum ether or ethyl alcohol), superheated steam is not supplied, the drum rotates, activating the extraction process; then the solvent is drained through pipe 5.
