Embodiment 1

[0026] A method for extracting clove oil, comprising the following steps:

[0027] (1) Mechanical activation: Dry the clove buds to make the water content 5%, take 1000g of the dried clove buds and put them into a vertical stirring ball mill, and mechanically activate them at a speed of 500r / min for 3 minutes to obtain clove powder;

[0028] (2) Soaking: Add the above-mentioned clove powder into the distillation tank, then add 0.5kg of cellulase and water, pressurize with a stone plate so that the water just soaks the clove powder, soak at room temperature for 5 hours, and obtain the extract;

[0029] (3) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 2 hours to obtain mixed steam;

[0030] (4) Condensation: the mixed steam obtained above is condensed through a condenser, and an oil-water mixture is obtained after condensation;

[0031] (5) Oil-water separation: the oil-wat...

Embodiment 2

[0035] A method for extracting clove oil, comprising the following steps:

[0036] (1) Mechanical activation: Dry the clove buds to make the water content 5%, take 1000g of the dried clove buds and put them into a vertical stirring ball mill, and mechanically activate them at a speed of 500r / min for 3 minutes to obtain clove powder;

[0037] (2) Soaking: Add the above-mentioned clove powder into the retort, then add 0.8kg of cellulase and water, pressurize with a stone plate so that the water just soaks the clove powder, soak at room temperature for 4 hours, and obtain the extract;

[0038] (3) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 2 hours to obtain mixed steam;

[0039] (4) Condensation: the mixed steam obtained above is condensed through a condenser, and an oil-water mixture is obtained after condensation;

[0040] (5) Oil-water separation: the oil-water mixture ...

Embodiment 3

[0044] A method for extracting clove oil, comprising the following steps:

[0045] (1) Mechanical activation: Dry the clove buds to make the water content 5%, take 1000g of the dried clove buds and put them into a vertical stirring ball mill, mechanically activate at a speed of 300r / min for 5min to obtain clove powder;

[0046] (2) Soaking: Add the above-mentioned clove powder into the distillation tank, then add 0.7kg of cellulase and water, pressurize with a stone plate so that the water just soaks the clove powder, soak at room temperature for 4 hours, and obtain the extract;

[0047] (3) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 2 hours to obtain mixed steam;

[0048] (4) Condensation: the mixed steam obtained above is condensed through a condenser, and an oil-water mixture is obtained after condensation;

[0049] (5) Oil-water separation: the oil-water mixture obt...

Abstract

The invention discloses a method for extracting clove oil. The method comprises the following steps: drying clove buds in the sun, mechanically activating, adding cellulase and water, immersing for 4-6h, carrying out distilling extraction for 1.5-2h, condensing mixed water steam obtained after distillation, carrying out oil-water separation on a condensed oil and water mixture to obtain crude clove oil, and carrying out extracting separation on the crude clove oil to obtain the clove oil. Mechanical activation treatment and immersion in cellulase are carried out before distilling extraction of the clove oil, so the oil yield is improved, and the distillation time is shortened; and the method also has the advantages of simple operation, low cost and high product purity, and is very suitable for industrial production.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to a method for extracting clove oil. Background technique [0002] Clove (Eugeniacaryophllata Thunb.) is a tree clove of the family Myrtleaceae. Clove oil is the essential oil extracted from clove buds. It can treat toothache, bronchitis, neuralgia, stomach acid, resist respiratory system and urinary system infection, relieve discomfort and pain caused by dysentery, improve weak constitution and anemia, and aphrodisiac (sexual Impotence, cold feeling), insect repellent. Promote blood circulation, treat skin ulcers and wound inflammation, treat scabies, and improve rough skin. At present, it has been widely used in the fields of medicine and health, daily chemical industry and so on. [0003] The extraction methods of clove oil are mainly steam distillation and organic solvent method. The existing water vapor has problems such as low extraction rate, long time consumption,...
