Description

Flower essential oil extraction is with evaporating dish mechanism

Technical Field

The invention relates to the technical field of flower essential oil, in particular to a steaming tray mechanism for extracting the flower essential oil.

Background

The essential oil is extracted from leaves, flowers, seeds, fruits, roots, barks, resins, hearts, etc. of plants by steam distillation, cold pressing, fat absorption or solvent method, and has high concentration of aromatic and volatile substances.

The hydrosol is condensed water solution obtained by distilling aromatic plants, oil and water can be separated in the distilling and extracting process, essential oil can float on the hydrosol due to different densities, and the hydrosol is precipitated on the hydrosol and is called the hydrosol. The pure dew contains small amount of essential oil components, and also contains water soluble substances in plant. It possesses a pure dew of one hundred percent of plant water-soluble substances, and its mineral nutrients (such as tannic acid and flavonoid) are lacked by essential oil. The low-concentration characteristic of the facial mask is easy to be absorbed by skin, no essence or alcohol component exists completely, the facial mask is mild and non-irritating, and the hydrolat can be used as daily product and can also replace pure water to prepare various facial masks and the like.

When using steam distillation method extraction essential oil and hydrolat, generally be high temperature extraction, can guarantee like this that essential oil can be abundant extract out, improve the rate of utilization of raw materials, reduce cost, but the hydrolat fragrance that obtains is not natural enough during high temperature extraction, often have the smell of kind "the flower of cooking", and the part also adopts the cryogenic distillation to realize the extraction to the hydrolat among the prior art, though the natural fragrance of hydrolat can be guaranteed to the cryogenic distillation extraction hydrolat low temperature, but nevertheless relatively poor to the extraction effect of essential oil, the realization that can not be abundant is to the extraction of essential oil, consequently need one kind promptly and can guarantee the natural fragrance of hydrolat, can guarantee the steaming tray mechanism of the extraction effect of essential oil again.
