Abstract
The invention provides a method for extracting eucalyptus leaf essential oil, comprising the following steps: (1) manufacturing a stainless steel net charging basket; (2) purifying and drying eucalyptus leaves by air, pulping the eucalyptus leaves into 20 meshes to 60 meshes, and putting the pulped eucalyptus leaves into the charging basket; (3) setting a distillation channel: stacking 4 to 8 stainless steel tubes at the bottom of a still pot to form a groined frame, putting the charging basket on the groined frame, and adding a cover on the charging basket; (4) soaking raw materials for 18 hours to 24 hours by adding purified water; (5) heating and distilling: remaining 1 hour after heating the solution to 60 EDG C to 70 DEG C, remaining 30 minutes after heating the solution to 78 DEG C to 85 DEG C, and generating an oil water mixture; (6) condensing oil water to 40 EGC C to 60 DEG C; (7) separating oil and water to obtain coarse oil of eucalyptus leaf oil; (8) refining the coarse oil: adding proper powdery tartaric acid to mix the coarse oil, allowing the coarse oil to stand for 22-24h, clarifying the coarse oil into essential oil after being filtered. The extraction method of eucalyptus leaf essential oil fills up the gap of eucalyptus leaf utilization, has simple technical devices, convenient operation, little investment, high work efficiency, low distilling temperature, short time, energy conservation, loss reduction and low cost and opens an approach for developing and utilizing eucalyptus.
Description
Technical field
The invention belongs to biochemical field, relate in particular to a kind of extracting eucalyptus leaf essential.
Background technology
Eucalyptus claims speed living eucalyptus again, is Myrtaceae, and arbor is tall and big and straight, and the four seasons are evergreen, area, the Yangtze valley, main producing region; China big area eucalyptus of planting always since the sixties, Ecodevelopment is good, becomes the forest products resource of horn of plenty.Eucalyptus is again the quick growing species of trees that light wood is used more; Eucalyptus is dried to be good timber materials, and folium eucalypti contains eucalyptus oil 1.2-2%, its staple cineole content about 80%; Eucalyptus leaf essential oil has the refrigerant fragrance of intensive; Have analgesic, antibacterial and anti-inflammation functions, can be applicable to daily-use chemical industry, biological medicine, fields such as air adjustment, environment protection; China except as the forest products resource greening environment, mainly is eucalyptus to be done use as the timber materials to the Application Research work of eucalyptus at present; Its eucalyptus leaves generally acts as a fuel; So far do not see the method appearance of extracting eucalyptus leaf essential oil, influenced the development and use of eucalyptus, the waste resource.
Summary of the invention
The objective of the invention is to fill up at present the blank of eucalyptus utilization, provide a kind of processing unit simple, easy to operate, less investment, cost are low, and work efficiency is high, from folium eucalypti, extracts the method for eucalyptus leaf essential oil.
Technical scheme of the present invention is: a kind of extracting eucalyptus leaf essential may further comprise the steps:
(1), make charging basket: make a stainless (steel) wire charging basket according to the still pot internal diameter, steel mesh density is 40 order holes;
(2), blank charging: purify the raw material folium eucalypti air-dry, blend into 20～60 orders size sheet, raw material is put into charging basket;
(3), distilling path is set: stack into the well cabinet frame at the bottom of 4～8 of the stainless steel tubes of cut-off footpath 2cm are placed in still pot, charging basket is put above it, make between the charging basket and the bottom of a pan and form distilling path; Add a cover the stainless steel square above the charging basket, prevent that the still-process raw material from overflowing;
(4), soak: add pure water and make the complete dip of raw material, 18～24 hours dip time, water level is higher than raw material physical layer 60cm;
(5), add thermal distillation: inspection raw material and charging basket are put intact, and pressure cooker cover closes; Distill operation, heat, heat again to 78～85 ℃ of maintenances 30 minutes to 60～70 ℃ of maintenances 1 hour; Under temperature and distillatory physical action, produce oil-water mixture; Distillation speed is: distillation amount hourly is a still pot volumetrical 10%;
(6), condensation: the oil-water mixture that distills is not with viscosity, gets into condenser condenses to 40～60 ℃;
(7), oily water separation: because profit density is different, chooses light oil water-and-oil separator and heavy oil water-and-oil separator and respectively the distillate that forms after the condensation is carried out the oily water separation operation, disengaging time 30～60 minutes gets slightly oil of eucalyptus oil;
(8), distillate oxidiferous extraction in the water, be to adopt the extraction of solvent one-level and heat up in a steamer the method that combines again;
(9) thick oil refining: add an amount of powdery tartrate in eucalyptus oil, stirred 3～5 minutes, placed 22～24 hours, clarify into essential oil after the filtration.
In said step (5), distillation speed is 1L/min, distillation time 1.5～2 hours.
In said step (9), the tartaric add-on of powdery is to press 0.5～1% of folium eucalypti oil mass to add.
Unusual effect of the present invention: processing unit is simple, and is easy to operate, less investment, work efficiency height; And owing to be provided with stainless (steel) wire charging basket and distilling path, avoided the sticking pot coking and contaminated when distillation of folium eucalypti profit, reduced to reload simultaneously and drag for the slag operation, alleviated the profit turbidity, guaranteed the aroma quality of essential oil; The heating distillation temperature is low, the time short, and is energy-saving and cost-reducing, reduces production costs; Add an amount of powdery tartrate, can remove the iron ion in the thick oil, produce antioxygenation, prevent the ester class saponification phenomenon in the essential oil, improve essential oil quality and stability.The eucalyptus leaf essential oil that the present invention extracts has the refrigerant fragrance of intensive, has analgesic, antibacterial and anti-inflammation functions, can be applicable to daily-use chemical industry, biological medicine, fields such as air adjustment, environment protection; Opened up the approach of eucalyptus development and use.
