Embodiment Construction

[0011] The technical solution of the present invention will be described in detail below.

[0012] A process for extracting citronella essential oil, comprising the steps of:

[0013] (1) Remove impurities from the citronella grass and dry the citronella grass leaves until the water content does not exceed 10%, and crush them to 40 mesh for later use.

[0014] (2) Use LED light to irradiate lemongrass grass grains: specifically, the illumination time of 15-25min is adopted, the illumination intensity is 15-20lx, and the color temperature of illumination is 5500-6000K; as an embodiment of the present invention, the LED light exposure time is 20 minutes, the light intensity is 20lx, and the light color temperature is 5500K. Certainly, as another embodiment of the present invention, the LED light irradiation time is 25 minutes, the light intensity is 15lx, and the light color temperature is 6000K; or, the LED light light irradiation time is 15min, the light intensity is 20lx, an...

Abstract

The invention discloses an extracting and processing technology for lemon grass essential oil. The extracting and processing technology comprises the following steps of (1) after trash extraction is performed on lemon grass, drying the lemon grass until lemon grass leaves of which the moisture does not exceed 10% are obtained, and crushing the obtained lemon grass leaves to 40 meshes for standby application; (2) illuminating lemon grass granules with LED light: specially adopting the illumination time of 15-25min, the illumination intensity of 15-20lx, and the illumination color temperature of 5500-6000K;(3) adding anhydrous ethanol of which the weight is 3 times of that of the lemon grass granules, and performing standing under 20 DEG C for 1h, so as to obtain a mixed solution; (4) placing the mixed solution treated in step (3) in a microwave extraction instrument, and under the condition of microwave power of 400w, performing microwave treatment for 10min; and (5) performing vapor extraction, refrigerating collected crude products in a refrigerator of 5 DEG C for 2h, and finally, performing centrifugation operation for oil-water separation.

Description

technical field [0001] The invention relates to the technical field of extracting essential oil from plants, in particular to a process for extracting citronella essential oil. Background technique [0002] With the continuous development of economy and society and the continuous improvement of people's living standards, the demand for plant essential oils is increasing. Essential oils are a general term for a class of oily liquids that are volatile, have a strong fragrance and smell, and can be distilled with water vapor. Essential oils have active ingredients and have a wide range of applications, such as eliminating phlegm and relieving cough, dispelling wind and invigorating the stomach, repelling insects, anti-wrinkle maintenance, etc. The essence of the most popular water therapy (SPA) is natural plant essential oils. For the extraction of essential oils, the current commonly used methods are steam distillation and solvent extraction, but there are disadvantages such a...
