Technical Field
The invention relates to the technical field of plant extraction and processing, in particular to a method for extracting natural plant essential oil.
Background
The natural plant essential oil is a cosmetic product. Is a highly concentrated liquid extracted from flowers, leaves, seeds, pericarps, branches, roots, stems, gums or oleoresins of plants. The essential oil has high volatility and small molecule, and can be easily absorbed by human body, and can quickly permeate into internal organs of human body to discharge redundant components out of human body, and the fragrance of the plant can directly stimulate the secretion of pituitary gland, the secretion of enzyme and hormone, etc., so as to balance internal functions and play the role of beautifying and protecting skin.
For high-quality essential oil, the flowering tops are usually extracted by adopting the flowering tops, the flowering tops are separated and then extracted respectively, but the operation is too complicated, the distillation efficiency is low, and after the high-quality essential oil is removed, the quality of the residual essential oil is relatively poor, so that the essential oil cannot be applied to aromatic physiotherapy, and the waste is caused to a great extent. Therefore, it is necessary to develop a high-efficiency and high-quality natural plant essential oil extraction method to reduce waste.

step three: placing the dried petal fragments in a screen mesh and putting the petal fragments in a distillation tower, continuously distilling the petal fragments for 30min by the distillation tower, and distilling out essential oil in the petal fragments for collection;
step four: collecting and cooling the distilled petal fragments;
step five: separating and storing the obtained essential oil;
step six: and D, placing the essential oil obtained in the fifth step into a distillation tower, and carrying out secondary rectification and finishing under the control of specific temperature, pressure and time to obtain the high-quality plant essential oil.
In a preferred embodiment of the invention, the cooled petal fragments collected in the fourth step are collected, mixed and distilled again to obtain the second-class plant essential oil.
In a preferred embodiment of the invention, in the first step, the petals of the plant are soaked by saline water, and the petals are cleaned by ultrasonic waves.
In a preferred embodiment of the invention, the plant petals are soaked in the saline for 1 hour in the third step, and then the saline is replaced.
In a preferred embodiment of the present invention, the essential oil obtained in step five is sterilized before being tested and packaged, and is sealed after being tested and packaged.
The invention has the beneficial effects that: the essential oil is prepared by decomposing, cleaning and distilling the flower tops of the plants, the obtained essential oil is subjected to secondary separation to obtain the high-quality essential oil, and the distilled petal fragments are collected for secondary distillation to obtain the two-class essential oil, so that the natural separation of the quality of the essential oil is realized, the step of essential oil separation is reduced, and the extraction efficiency of the high-quality essential oil is improved.
