SU1253994A1 - Horizontal counter-flow extractor for producing essential oil - Google Patents

Description

The invention relates to the ether oil industry and can be used to extract the essential oil from the essential oil raw material.

The purpose of the invention is to increase productivity and increase oil yield, as well as to prevent clogging of sprinklers.

Fig. 1 schematically shows a horizontal countercurrent extractor for producing an essential oil; figure 2 - section aa in figure 1; in FIG. 3, view B in FIG. 2; Fig, 4 - extractor., Incision; FIG. 5 is a section B-B in FIG. 4; Fig, 6 is a view of g on .fig, 5; FIG. 7 is a section D-D of FIG. 4; on Fig - General view of the extractor.

The extractor comprises a screw section 1, the body of which in its upper part has a window 2 for loading. Before the section is concentric with the shaft 3 of the screw 4 there is installed a chamber 5 for loading and soaking the raw material with a hopper 6 for feeding material, a discharge nozzle 7 for the miscella and blade-8 mounted on the shaft,

Butt end of the section; closed from the side of the chamber 5.

The device is equipped with sprinklers for the overflowing bowls. SH1Y installed on both sides of the window 2 for loading the raw material extending beyond the body of section 1. The chamber 5 for loading and soaking the raw material has the shape of a truncated cone mounted to the smaller section 1. pitched blades 9, and the nozzle 7 dp of removal of miscegpa is located below section 1.

Preferably, the device is designed in which the orositeller is exaggerated in the form of a plate 10c.

Which 11, directed to: bottom.

Above section 1, an upper auger section 12 is installed, with a pre-discharge Leium 13 for unloading. Sections and 12 are connected by reloading column 14, the bottom 15 of the chamber 5 is perforated. Under it is installed sediment. 16 for moisture and cell sap. To supply the solvent serves as a pipe 17.

The angle of inclination of the blades 9 is set taking into account the coefficient of friction sliding.

The essential oil material is fed through the hopper 6, which is located at some distance from the end of the screw section 1J, into the chamber 5 for soaking, where it is rotated by the rotating blades 8 forcibly immersed into the solvent below the screw section I. After immersion The raw material on the blade x 8 rises above the level of solvent. until the angle of elevation exceeds the angle of repose of the soaked raw material and it moves, the pitched blades 9, which deflect it towards the screw section 1, meet in their path.

During lifting and movement of the raw material on the blade 8, the solvent is separated from it. In chamber 5, the amount of solvent at the bottom is not the same and minimally in the zone of the window 2 of the screw section 1, In this zone during the stay on the blade x 8 and under the screw section 1, where the minimum of solvent, the wetted raw material is irrigated and progressed by a less concentrated miscella flowing from the auger section 1 through the plates 10, and is directed to extraction into section 1 through reloading column 14 to section 12 and discharged from the extractor.

The solvent enters the extractor through the nozzle 17 and moves towards the raw material through the upper section 12 to the lower}, where it is poured into the chamber 5 and discharged as a miscella through the nozzle 7.

In chamber 5, the raw material is repeatedly immersed in a solvent, actively mixed, watered with a solvent, and separated from it before being fed to the extraction in the auger section. Day 1. This allows in less than 1 minute in chamber 5 to extract up to 70% of the extract from the raw materials and to intensify the extraction process as a whole.

Completion of the chamber dp of loading and charging of the raw material in the form of a truncated cone mounted with a smaller base in the direction of the auger section and placement of a branch pipe for drainage

Miscella below this section, allows to stabilize the level of miscella in the extractor, the necessary dp to improve its performance.

The fact that the sprinkler extractor has for transferring miscellas installed on both sides of the window for loading from raw materials beyond the shell, equipping the blades of the blades makes it possible to extract most of the extract from the raw material before feeding it into the screw section. Making the sprinklers in the form of a plate with jagged edges pointing downward allows the solid stream of solvent to be broken up into separate jets. it

prevents clogging of sprinklers and promotes even distribution of the solvent (miscella) over the surface of the underlying raw material in order to intensify its processing and increase the yield of oil.

When using the invention, the specific productivity of the extractor is increased by 25%, the oil yield is increased to 10% and the extraction time is reduced by 25%.
