Abstract
The invention relates to a preparation method of high-purity essential oil by low-temperature distillation extraction. The method comprises the following steps: (1) smashing reaped fresh plants in a stirrer; (2) putting the smashed plant material into a distillation plant, and carrying out vacuum low-temperature distillation at 40-60 DEG C, and introducing the distilled vapor flow into the plant material to obtain an oil-water mixed gas flow; (3) after the oil-water mixed gas flows through a condenser, carrying out heat dissipation to obtain a plant essential oil-water mixed liquid; (4) passing the mixed liquid through the oil-water separator to form stratified oil water, and collecting the supernatant oil layer by using a collector; and (5) circulating the steps (2)-(4) 2-3 hours to obtain the high-purity essential oil. The vacuum low-temperature distillation process is utilized to refine the natural plant essential oil; only water is added in the purification process, thereby preventing the impurities from mixing, and enhancing the purity of the natural plant essential oil; and only an oil-water separation technique is needed in the later period, thereby simplifying the later treatment technique, and enhancing the quality of the essential oil finished product. The highest purity can reach 99%.

Background technology
Natural plant essential oils is a kind of cosmetic products, be a kind of flower from plant, leaf, seed, peel, branch, root, stem,
Extracting, in natural gum or oleoresin, the highly concentrated liquid extracting, common plants essential oil has Flos Rosae Rugosae quintessence oil, arborvitae quintessence oil, chaste tree
Bar quintessence oil etc..
The extracting method of existing natural plant essential oils mainly has:
1, fat absorption method, utilizes the quintessence oil in oils and fats absorption Flos Rosae Rugosae, although technique is simple, but later separation quintessence oil with
Oils and fats is the most difficult.
2, extraction, use low boiling point solvent such as the organic solvent such as petroleum ether, hexane immersion Flos Rosae Rugosae, be obtained by extraction quintessence oil with
And the mixture of organic solvent, organic solvent is then distilled off, obtains Flos Rosae Rugosae quintessence oil；This kind of method extraction of essential oil rate height, one-tenth
This is low, but easily causes organic solvent residual, makes Flos Rosae Rugosae quintessence oil fragrance the purest.
3, supercritical extraction, uses supercritical carbon dioxide fluid to soak, Flos Rosae Rugosae quintessence oil is obtained by extraction；This kind of method tool
There is yield high and high quality；But owing to supercritical carbon dioxide fluid dissolubility is too strong, the non-essence in Flos Rosae Rugosae
Oil component also is extracted out, and the moisture content in Flos Rosae Rugosae is not readily separated so that Flos Rosae Rugosae quintessence oil is easy mildew during storage,
Limit the range of application of products obtained therefrom.
In order to solve the problems referred to above, need a kind of production technology that can produce high-purity quintessence oil.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of low temperature distillation extracting high purity quintessence oil, it is achieved prepare quintessence oil pure
The preparation method of the low temperature distillation extracting high purity quintessence oil of degree up to more than 95%.
It is an object of the invention to be achieved through the following technical solutions:
The preparation method of a kind of low temperature distillation extracting high purity quintessence oil, comprises the following steps:
(1) fresh plant of harvesting is put into blender to smash；
(2) plant material after smashing puts into vaccum cryogenic distillation in distillation equipment, vapo(u)rizing temperature 40 °-60 ° it
Between, by the steam air-flow introduced plant material of distillation, make the quintessence oil steam of plant material mix with steam air-flow, it is thus achieved that oil
Water mixed airflow；
(3) described oil mixing with water air-flow dispels the heat after condenser, gas phase become liquid phase, obtains plants essential oil and water
Mixing liquid；
(4) described mixing liquid is layered by forming profit after oil water separator, uses catcher to collect upper strata oil reservoir；
(5) step (2) circulates 2-3 hour to (4), obtains high-purity quintessence oil.
In preferred embodiments, described in step (1) harvesting fresh plant be full color, nuisanceless and without moth
The root of the natural plants of worm, stem or leaf, clean surface contaminants with water after harvesting, dries after then soaking 5-10 minute at cool place.
In preferred embodiments, described in step (2), oil mixing with water air-flow is sterilized by ultraviolet mycete lamp.
In preferred embodiments, described fresh plant be Flos Rosae Rugosae, lavandula angustifolia, bud cypress, Vitex chinensis Mill., Camellia sinensis, Herba Rosmarini Officinalis, jasmine
Any one in jasmine, Flos Inulae, Flos Matricariae chamomillae, Fructus Citri Limoniae, Herba Menthae, Salvia japonica Thunb..
The invention have the benefit that
The present invention utilizes vaccum cryogenic distillation method to refine extracting natural plants essential oil, and purification process only adds water, does not has it
His any additive, it is to avoid impurity is mixed into, and improves the purity of natural plant essential oils, and the later stage has only to carry out oil-water separation work
Skill, simplifies the process technique in later stage, not only substantially reduces extraction time, and the process of extraction is thermally-stabilised, makes derived essential oil not
Destructible and volatilization loss, improve the mobility of quintessence oil, improves the quality of quintessence oil finished product, and highest purity can reach 99%.
