[0017] Examples:
[0018] A process for extracting lavender essential oil includes the following steps:
[0019] Step a. Pick up fresh lavender, wash with clean water, dry the lavender branches and leaves naturally, and then add them to a stirring ball mill, and mechanically activate 5-10min at a speed of 300-500r / min to obtain lavender powder;
[0020] Step b. Add sodium chloride solution at a ratio of 1:5 by mass ratio of powder to water, and soak for 4-5 hours; wherein the concentration of sodium chloride solution is 20%-25%;
[0021] Step c. Transfer to the distillation device for atmospheric distillation, pass steam from the bottom of the distillation tank to heat the extract, and heat the extract to 110°C-125°C. After the extract boils, extract 1.5-2h to obtain mixed steam; to the condensate Drop on the glass plate, get an oil-water mixture after condensation, stop the distillation when no oil drop appears;
[0022] Step d. Oil-water separation: the oil-water mixture obtained by ...
