Abstract

The invention relates to a method for extracting eucalyptus essential oil by a distillation method, belonging to the technical field of industrial processing, and solving the problem of flexible extraction of eucalyptus essential oil. The method mainly comprises the following steps: 1, preparing raw materials including fresh eucalyptus branches and eucalyptus leaves; 2, preparing instruments including a shredding machine, a distilling still, a delivery pipe, a liquefying pot and a condensing pot; 3, cleaning up sand and erasing deadwood; 4,shredding the raw materials into crushed aggregates with the shredding machine; 5, putting the crushed aggregates into the distilling still in which the distillation temperature is greater than or equal to 100 DEG C and less than or equal to 110 DEG C, and leading out the distilled mixed vapor from the top delivery pipe; 6, delivering the mixed vapor through the delivery pipe to the liquefying pot in which a low-temperature annular pipe is arranged and the liquefying temperature is greater than 0 DEG C and less than 10 DEG C, and liquefying the mixed gas into mixed liquid; and 7, delivering the mixed liquid into the condensing pot in which the condensing temperature is greater than or equal to -5 DEG C and less than 0 DEG C, and separating the ice layer to obtain the supernatant oily liquid, namely the eucalyptus essential oil.

Description

A kind of method that way of distillation extracts eucalyptus oil

Technical field

The present invention relates to the method that eucalyptus oil is extracted from Eucalyptuss branch and leaf, belongs to agricultural machining technical field.

Background technology

Eucalyptuss, are also eucalyptus globoluss tree, Myrtaceae（Myrtaceae）.Aiphyllium, bark or thick thick and harbor, or it is flat Slide and come off every year.Leaf amphitypy, juvenile leaf stockless and opposite, climax leaves crescent or Long Circle have volatile aromatic oil.Seed is more Number, only a few can educate.Eucalyptuss species is various, there is 522 kinds and 150 mutation.Majority originates in Australia, 19th century Introduce a fine variety all over the world, there are 96 countries to have cultivation.

In 19th-century latter stage, eucalyptus leaveses had been considered as once a kind of catholicon.Australia original inhabitants spread on the Folium eucalypti globueli (Eucalyptus globulus Labill.) smashed to pieces On wound, wound healing situation is unexpectedly good.Due to eucalyptus globuluss for air has disinfective action, therefore Eucalyptuss are lived in Environment in, be conducive to health.The maximum effect in application of eucalyptus globuluss quintessence oil is all effective to various inflammation and fever. For the sufferer having a high fever, eucalyptus globuluss quintessence oil can rapidly produce the hypothermic effect of drop.Eucalyptus globuluss quintessence oil is one of best antibacterial, There is very strong sterilizing power, while also have reducing the effect of internal mucous viscosity, thus can be used for physical therapy pulmonary tuberculosis, bronchus Inflammation, diphtheria etc., can relax inflammation phenomenon and make mucosa comfortable.Eucalyptus globuluss quintessence oil has spasmolytic, pain relieving, alleviates muscular soreness and rheumatism The effect such as pain, often to make an addition in basic massage oil relax muscle rigidity by massaging and ache and waits discomfort.Eucalyptus leaveses have sterilization Effect Japanese Okayama Univ. professor shore Tian Boxi and researcher Fu Liangde et al. are found through experiments, and the culture of Eucalyptuss leaf is thin Born of the same parents can effectively eliminate the toxicity of harmful chemical bisphenol-A.Bisphenol-A is a kind of compound, is usually used in plastics and manufactures with coating Aspect, it has recently been found that the material is reduced the possibility such as sperm quantity of animal, therefore is put into " environmental hormone " in Japan -- disturbs The list of the chemical substance of random hormonal system function.According to shore field professor recently to media, they are being processed into graininess Eucalyptus leaveses cultured cells be put into concentration for 1PPM（Hundred a ten thousandths）Bisphenol-A solution in, after three days find bisphenol-A toxicity Disappear, be changed into innocuous substance.According to another fine male Jie in ecological technique company manager autumn fields of research of cooperating with two scientists Continue, this function of eucalyptus leaveses can be further strengthened by transgenic technology, at present, the said firm is just being devoted to this Technology further develops perfect, is finally reached practical stage, produce can practical application environment-friendly products.

The refrigerant pleasant breath of eucalyptus globuluss quintessence oil, makes one in high spirits, clearheaded, attention concentration.Eucalyptus globuluss quintessence oil has elimination Pore obstruction, the effect for eliminating acne, blood circulation promoting, helping tissue regeneration.Eucalyptus oil is extracted at present mainly takes pressure Liquid concentration extraction method, solvent extraction method are squeezed, in general, the more soft plant part such as leaf, flower is not required to through pre-treatment Squeezing is can be carried out, but the moisture in Eucalyptuss is less, the liquid component minimal amount for squeezing out, and substantial amounts of eucalyptus oil composition is also It is present in slag body and causes to waste.

The content of the invention

In order to produce the eucalyptus oil of certain purity, the demand in market is met, a kind of way of distillation of my invention is extracted The method of eucalyptus oil, this method extracts simple, and processing is simple, and small investment brings notable results, and extraction ratio is high, is suitable for field and adds Work is extracted, and eliminates the cost of transportation problem of Eucalyptuss branch and leaf.

A kind of way of distillation extracts the method solve problem of eucalyptus oil and adopts the technical scheme that to enter by below step OK：First, raw material used：Fresh Eucalyptuss branch, eucalyptus leaveses；2nd, instrument used：Cut up with a hay cutter broken machine, boiler, delivery pipe, liquefaction Tank, drainer；3rd, fresh Eucalyptuss branch, eucalyptus leaveses are removed into silt particle and eliminates deadwood；4th, raw material hand hay cutter is broken into hand hay cutter broken machine Particle；5th, particle is put in boiler, stacks thickness 15cm ~ 20 cm, dig out one at interval of 10cm ~ 15cm and vertically breathe freely Hole, rises high-temperature and is distilled, and 110 DEG C >=vapo(u)rizing temperature >=100 DEG C, the mixing vapour for distilling out is drawn from the delivery pipe of top； Six, mixing gas reaches liquefied pot by delivery pipe, there is cryogenic toroidal pipe, 0 DEG C of 10 DEG C of ＜ condensing temperature ＜, mixing in liquefied pot Gas is liquefied as mixed liquor；7th, mixed liquor is delivered to into drainer, 0 DEG C of -5 DEG C≤condensation temperature ＜ separates out ice sheet, upper strata Oily liquids are eucalyptus oil.

A kind of method that way of distillation extracts eucalyptus oil, using water distillating method, distillation high temperature vapour is tedge, liquid of lowering the temperature It is down-comer during change, is easy to liquefied liquid to dirty, the temperature liquefied in pipe is unsuitable too low, in order to avoid the obstruction pipe that freezes in pipe.

A kind of way of distillation extracts the beneficial effect of the method for eucalyptus oil：A kind of method that way of distillation extracts eucalyptus oil Using Eucalyptuss branch and leaf as extracting raw material, by cut up with a hay cutter it is broken after put into and carry out heating into boiler and distill out mixing water vapor body, then lead to Cross annular liquefaction pipe cooling liquid；Make use of eucalyptus oil different from water-cooled solidification temperature again, the cooling in drainer will be mixed Close the moisture in vapour and all separate out precipitation, obtain high-quality eucalyptus oil；Compare a kind of way of distillation of other extracting method to extract The method of eucalyptus oil is simple using instrument, simple to operate, flexibly can carry out extraction operation by moving area.
