Abstract
The invention relates to the technical field of flower essence extraction, in particular to a cherry flower essential oil extraction method. The method comprises the following the steps: purifying dried cherry flowers, drying and smashing to 10 meshes for later use; adding an extraction agent in an amount which is 4 times the weight of the cherry flowers to extract by 3 times, standing at the temperature of 22 DEG C for 10 h, and filtering to obtain extract liquor, wherein the extraction temperature is 18 DEG C, and the extraction pressure is 0.3MPa; placing the extract liquor on an evaporator, and evaporating under a reduced pressure and at a low temperature to evaporate the extraction agent out so as to obtain cherry flower extract, wherein the reduced-pressure low-temperature evaporation is performed under the pressure of 0.08 MPa and at the temperature of 30 DEG C; putting the cherry flower extract into a separating tower, performing flash evaporation, and collecting a gas-state product to obtain cherry flower essential oil, wherein the flash evaporation in the separating tower is performed at the temperature of 80 DEG C and under the pressure of 100Pa, and heating time is 3 seconds. Compared with the prior art, the cherry flower essential oil extraction method has the beneficial effects of easiness in operation, high quality of the prepared cherry flower essential oil, and oil yield of being up to 0.08 percent.
Description
Technical field
The present invention relates to from the technical field spending middle extraction quintessence oil, particularly to a kind of cherry blossom method of extraction of essential oil.
Background technology
Cherry blossom is nutritious, and it contains substantial amounts of carotene, Vc, protein, and phosphorus, calcium, iron content all arrange various fruit first.The traditional Chinese medical science is thought: Fructus Pruni pseudocerasi sweet in the mouth, warm in nature, has QI invigorating in tune, body-building function, can improve body immunity, is optimal nutrition and health care product in fruit, and U.S.'s large cherry is called " gem fruit ".Therefore, the present invention provides a kind of process extracting cherry blossom quintessence oil, simple, extraction quality height, oil yield height.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of cherry blossom method of extraction of essential oil.
For achieving the above object, the technical solution used in the present invention is:
A kind of cherry blossom method of extraction of essential oil of the present invention, comprises the steps:
A, by dry cherry blossom remove impurity, be dried, be crushed to 10 mesh, standby；
B, addition weight are that the extractant of cherry blossom weight 4 times extracts 3 times, stand 10h, filter, obtain extract at 22 DEG C；Extraction conditions is 18 DEG C, 0.3MPa；
C, extract being placed vaporizer, reduce pressure low-temperature evaporation, and extractant is evaporated, i.e. can get cherry blossom extractum；The condition of decompression low-temperature evaporation is 0.08MPa, 30 DEG C；
D, by cherry blossom extractum put into knockout tower, flash distillation, collect gaseous products i.e. can get cherry blossom quintessence oil；Knockout tower flash conditions is 80 DEG C, 100Pa, heated time 3 seconds.
Further, described extractant by 40% 90%(volume) ethanol and 60% petroleum ether form.
The present invention compared with prior art provides the benefit that: this method is simple to operate, and the cherry blossom quintessence oil quality of preparation is good, and oil yield is up to 0.08%.
Detailed description of the invention
Describing the present invention below in conjunction with specific embodiment, following embodiment and explanation are only used for explaining the present invention, but not as a limitation of the invention.
A kind of cherry blossom method of extraction of essential oil of the present invention, comprises the steps:
A, by dry cherry blossom remove impurity, be dried, be crushed to 10 mesh, standby；
B, addition weight are that the extractant of cherry blossom weight 4 times extracts 3 times, stand 10h, filter, obtain extract at 22 DEG C；Extraction conditions is 18 DEG C, 0.3MPa；
C, extract being placed vaporizer, reduce pressure low-temperature evaporation, and extractant is evaporated, i.e. can get cherry blossom extractum；The condition of decompression low-temperature evaporation is 0.08MPa, 30 DEG C；
D, by cherry blossom extractum put into knockout tower, flash distillation, collect gaseous products i.e. can get cherry blossom quintessence oil；Knockout tower flash conditions is 80 DEG C, 100Pa, heated time 3 seconds.
Further, described extractant by 40% 90%(volume) ethanol and 60% petroleum ether form.
The present invention compared with prior art provides the benefit that: this method is simple to operate, and the cherry blossom quintessence oil quality of preparation is good, and oil yield is up to 0.08%.
The above is only in order to the convenient explanation present invention, in scope create without departing from the present invention, is familiar with the various simple covert and modification that those skilled in the art of this technology done and should belong to protection scope of the present invention.
