RU2319736C2 - Drum unit for extracting of essential oils from flower-and-grass raw material - Google Patents

Abstract

FIELD: essential oil production.

SUBSTANCE: drum unit has heat-insulated chamber with hermetically mounted heat-insulated cover equipped with branch pipe for discharge of vapor saturated with essential oil. There are branch pipes for discharge of condensate and feeding of overheated vapor on the bottom of heat-insulated chamber. Within heat-insulated chamber there is drum provided with perforated bottom and drive shaft. Drum is mounted in horizontal position and is axially aligned with heat-insulated chamber walls. Supporting disk with cam-like stirrer and drive pulley with drive system are put onto drive shaft.

EFFECT: increased efficiency in separation of essential oils and utilization thereof in mobile version.

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 thermally 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 producing extracts from citrus fruits (see patent SU 1823880 А3, 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 disk is mounted on the axis (shaft) of the drum. 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 and the use of shock from floral-grassy raw materials.

This task is achieved in a drum apparatus for extracting essential oils from floral-grassy raw materials with a horizontal arrangement of the drum, comprising a housing with a coaxially arranged drum, a cover and a drive shaft mounted coaxially with the drum and the housing, where according to the invention the housing is made in the form of a heat-insulated chamber with a hermetically mounted and a thermally insulated lid having a pipe on itself for venting vapors of essential oils, in addition, the bottom of the thermally insulated chamber has pipes for supplying superheated Steam and condensate drain, and the drum is mounted on the shaft, wherein the drum shaft is equipped with a supporting ring resting on a shaker in the form of a cam.

Unlike the prototype, 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 able to rotate, being mounted on a shaft equipped with a support disk resting on a shaker, which throws up the raw materials in the drum, preventing it from caking. Under the influence of shock load and superheated steam containers containing essential oils are destroyed much faster, contributing to a more rapid release of essential oils. The amplitude of the shaking, determined by the eccentricity of the cam, is equal to the value of the minimum particle of raw materials, and the rotation frequency of the cam corresponds to the frequency of the alternating current in the network (50 hertz).

The invention is illustrated in the drawing, which shows a General view of a drum apparatus for the extraction of essential oils.

A drum apparatus for extracting essential oils from flower-herbaceous raw materials 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; on 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 heat-insulated chamber 1 there is a perforated drum 6 mounted on the shaft 7 with a support disk 8, supported by a shaker 9 in the form of a cam and driven by a drive pulley 10 and drive system 11.

The drum apparatus for extracting essential oils from flower-herbaceous raw materials has a horizontally located drum and operates as follows: raw material is loaded into the perforated drum 6 located in the heat-insulated chamber 1, and the chamber 1 itself is hermetically closed by a heat-insulated lid 2, through the pipe 4 located on bottom of chamber 1, superheated steam is supplied. Essential oils are softened, the containers of essential oils burst, and the essential oils evaporate and, mixed with water vapor, are discharged into the distiller through a pipe 3 located on the lid of the chamber 2, condensate and intercellular fluid are drained from the chamber by a pipe 5. To intensify the process of extracting the essential oil, perforated the drum 6, mounted on the shaft 7, is subjected to the shock load caused by the shaker 9, made in the form of a cam, through the support disk 8 of the shaft 7, which is driven by the drive system 11 of the drive pulley 10.

A drum apparatus for extracting essential oils from floral-grassy raw materials with a horizontal drum arrangement allows:

- increase the yield of essential oils from essential oil raw materials through the use of an additional impact factor - shock load;

- reduce energy consumption for the preparation of steam by lowering the temperature to sufficient for the destruction of the containers of essential oils with the use of shock;

- maintain the structure of essential oil raw materials, as a result of which it can be used to obtain essential oils by extraction.
