Abstract

Usage: the invention relates to equipment for the essential oil industry and can be used in the processing of plant materials. SUMMARY OF THE INVENTION: The installation consists of a successively arranged feed screw column with an inclined feed hopper, a preliminary screw column (K) and vertical distillation columns) with steam supply nozzles. K has in the upper part a reloading chamber with distribution blades. in which bypass openings are made for communicating with each of K. 2 C.p. 5 ill.

Description

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

A known plant for distilling essential oils from vegetable raw materials is known.

The disadvantage of this installation is that for the distribution of raw materials in the distillation columns it has a screw concentrator, its presence increases the ore and metal consumption and, moreover, it does not provide a uniform distribution of raw materials in the distillation columns, which is almost impossible to do continuously.

The aim of the invention is to increase the plump; extracting the essential oils by improving the distillation conditions.

This goal is achieved in that in the installation for the distillation of essential oils from vegetable raw materials, consisting of preliminary screw vertical stripping columns, nodes for loading raw materials and unloading waste, pipes for supplying steam and exhaust vapor for condensation, the preliminary screw column has a reloading column in the upper part a chamber with bypass openings for connecting and communicating with at least two distillation columns connected in pairs in the lower part by a common chamber with an unloading screw in it. having opposite windings under each distant column, the loading pipe of the lifting column is connected to the pipe of the loading mechanism with the possibility of rotation of the latter around its axis, which made it possible to combine the loading unit with the receiving hopper - dispenser, abandoning the feed conveyor.

Figure 1 schematically shows the proposed installation, side view: figure 2 is a section aa in figure 1: Fig. 3 is a section bb in figure 2, a plan view; in Fig.4 is a section GG in Fig.Z; figure 5 - section bb in figure 2.

Installation for distillation of essential oils from vegetable raw materials contains a mechanism 1. containing a loading hopper 2 with a pipe with a metering

ABOUT

relative to the axis of the loading pipe 4 on the feed screw column 5.

The feed screw column 5 comprises a cylindrical body, within which a conveying screw 6 is placed, ending in the upper part with a blade 7.

At the top of the column there is a circular transfer chamber 8 with a bypass opening 9 for connecting and communicating at least 2 distant columns 10 arranged around the preliminary screw column at the corners of the rectangle.

The distillation columns 10 are vertical hollow cylindrical columns within which axial bubblers 11 are located, each pair of distillation columns is connected in the lower part via a discharge unit 12, with an unloading screw 13 therein, the feather of the screw under each distillation column have opposite windings.

The bottom of the reloading chamber 8 is perforated and has a jacket with a nozzle 14 for draining condensate and cell juice. A nozzle 15 is used to vent condensation vapors.

The installation works as follows. A dump hopper 2 of the loading mechanism 1 is lowered to the lower position and the dump truck enters with crushed raw materials, unloads in it and drives out. Then, using the hydraulic cylinders, the feed hopper rises to the angle of repose of the raw material (45-60 °). The feed in the tray slides towards the metering screw 3 and abuts against it, and when the screw is turned on, the feed is dosed into the feed column 5. The screw feed column is transported up to the circular loading chamber 8, where it is

by means of a blade, it is evenly distributed over the distillation columns 10. Pass from top to bottom along the distillation columns, raw materials using the unloading screw 13 of the unit

discharges 12 are withdrawn from the installation.

In the distillation columns 10, the essential oils are distilled off with steam, which is supplied through bubblers 11.

Water vapor with vapors of essential oils

condensate is diverted through pipe 15 to condensation.

Claims (3)
