Abstract
The invention discloses a method for preparing the aquilaria essential oil, and belongs to the technical field of manufacturing and extracting essential oils, which comprises a steam distillation column and a vacuum control distillation column. The feed port of the steam distillation column is connected with crushed agarwood and water. The reaction discharging port of the steam distillation column is connected with an oil-water separator. The distilled water and the distilled oil are separated. The distilled water is circularly fed into the steam distillation column and the distilled oil is fed into the vacuum control distillation column. The distillation column of the vacuum control distillation column is placed in a heating jacket and two pipes are led out of the pylon of the column, wherein the lower pipe serves as an essential oil outflow pipe and the upper pipe serves as a vacuum control pipe. A set of condensers is arranged between the ports of the two pipes. The vacuum control pipe is provided with a vacuum valve and the end portion thereof is connected with a vacuum device. A condenser is arranged in the essential oil outflow pipe. According to the invention, the vacuum distillation technology is combined with the vapor distillation technology, so that the refined aquilaria essential oil can be extracted. The extraction time is greatly shortened and the thermal stability of the extraction process is ensured. The components of the essential oil are less susceptible to damage and volatile loss, and the flowability of the aquilaria essential oil is improved. Meanwhile, the product quality of the aquilaria essential oil is improved.
Description
Technical field
The present invention relates to acetals spices manufacture technology field, be specially a kind of agilawood essential oil preparation method.
Background technology
Agalloch eaglewood has causing resuscitation with aromatic drugs, pain relieving, the meridian dredging, calms the nerves, relieving convulsion, convergence is dispeled the wind, good effect is had to calm, the adjustment of nervus centralis, in traditional Chinese medical science drug effect, it is the purging medicine of fragrant strengthening the spleen and stomach, controlling the circulation of vital energy in the wrong direction breathes heavily effective in especially retention of urine, nervous vomiting, stomachache, dysthymic uncomfortable in chest, stomach colic, liver depression is not relaxed, stenocardia etc. is all effective.
Most of agalloch eaglewood almost can't smell fragrance under normal conditions, then give off a strong fragrance when smouldering, other smell can be covered, and fragrance remaining time is very long, be the high-grade spices manufacturing volatile oil and natural perfumes, agalloch eaglewood is higher containing the amount of volatile oil, has strong fragrance, be the main component of agalloch eaglewood volatility drug effect, its amount containing volatile oil is directly relevant to the quality of medicinal material.
Steam distillation method is the common method extracting agalloch eaglewood ethereal oil at present, and not only the time is long, and in leaching process, easily cause destruction and the volatilization loss of thermally labile and oxidizable composition, has destruction to fractions.
Vacuum environment can reduce the boiling point of liquid, is more easily separated compatible substances.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of agilawood essential oil preparation method, vacuum distilling control techniques and steam distillation method combine by it, refinement agilawood essential oil can be refined, not only substantially reduce extraction time, and leaching process is thermally-stabilised, make the survivable and volatilization loss of derived essential oil, improve the mobility of agilawood essential oil, improve the quality of agilawood essential oil finished product.
Technical solution problem of the present invention adopts following technical scheme:
A kind of agilawood essential oil preparation method is provided, it comprises vapor distillation tower and vacuum control distillation tower, it is characterized in that: described vapor distillation tower opening for feed is connected to pulverizes agalloch eaglewood and water, reaction discharge port is connected to water-and-oil separator, water-and-oil separator isolates distilled water and distilled oil, in water needed for distilled water circulation access vapor distillation tower, vacuum control distillation tower described in distilled oil access, described vacuum control distillation tower, its distillation tower is placed in heating jacket, the king-post of distillation tower draws two pipelines, what be positioned at lower end is essential oil outlet pipe, what be positioned at upper end is vacuum control pipe, one group of condenser is installed between two pipeline opening, described vacuum control pipe is provided with vacuum valve, end connects vacuum unit, in described essential oil outflow conduit, one group of condenser is installed.
As preferred embodiment, do not have water in the distillation tower of described vacuum control distillation tower, described distilled oil directly accesses in distillation tower.
As preferred embodiment, described vapor distillation tower carries out steam distillation when having an output distilled oil, the vacuum valve of immediate unlock vacuum control distillation tower, and starts to heat to heating jacket.
The present invention is compared with existing, its beneficial effect is: vacuum distilling control techniques and steam distillation method combine, refinement agilawood essential oil can be refined, not only substantially reduce extraction time, and leaching process is thermally-stabilised, make the survivable and volatilization loss of derived essential oil, improve the mobility of agilawood essential oil, improve the quality of agilawood essential oil finished product.
