Embodiment 1
[0027] A method for improving the extraction rate of valerian essential oil, the steps are as follows:
[0028] (1) the valerian root of gathering is dried, and its moisture content is 8.5%;
[0029] (2) mechanical activation: add the dried valerian root in the stirring ball mill, and mechanically activate it for 7 minutes at a rotating speed of 90r / min to obtain the valerian root powder;
[0030] (3) Enzymolysis treatment: use compound enzyme to treat valerian root powder at 45°C for 2.5 hours;
[0031] (4) Distillation: feed water vapor from the bottom of the retort to heat the extract, and extract for 2 hours after the extract boils to obtain mixed steam;
[0032] (5) Condensation: the mixed steam obtained above is condensed through a condenser, and the oil-water mixture is obtained after condensation;
[0033] (6) oil-water separation: the oil-water mixture obtained by condensation is carried out oil-water separation through the oil-water separator to obtain valerian cru...
Embodiment 2
[0036] A method for improving the extraction rate of valerian essential oil, the steps are as follows:
[0037] (1) the valerian root of gathering is dried, and its moisture content is 10%;
[0038] (2) mechanical activation: add the dried valerian root in the stirring ball mill, and mechanically activate it for 5 min at a rotating speed of 100r / min to obtain the valerian root powder;
[0039] (3) Enzymolysis treatment: use compound enzyme to treat valerian root powder at 45°C for 2.5 hours;
[0040] (4) Distillation: feed water vapor from the bottom of the retort to heat the extract, and extract for 2 hours after the extract boils to obtain mixed steam;
[0041] (5) Condensation: the mixed steam obtained above is condensed through a condenser, and the oil-water mixture is obtained after condensation;
[0042] (6) oil-water separation: the oil-water mixture obtained by condensation is carried out oil-water separation through the oil-water separator to obtain valerian crude o...
Embodiment 3
[0045] A method for improving the extraction rate of valerian essential oil, the steps are as follows:
[0046] (1) the valerian root of gathering is dried, and its moisture content is 12%;
[0047] (2) mechanical activation: add the dried valerian root in the stirring ball mill, and mechanically activate it for 5 min at a rotating speed of 110r / min to obtain the valerian root powder;
[0048] (3) Enzymolysis treatment: use compound enzyme to treat valerian root powder at 50°C for 3 hours;
[0049] (4) Distillation: feed water vapor from the bottom of the retort to heat the extract, extract after boiling for 2.5 hours to obtain mixed steam;
[0050] (5) Condensation: the mixed steam obtained above is condensed through a condenser, and the oil-water mixture is obtained after condensation;
[0051] (6) oil-water separation: the oil-water mixture obtained by condensation is carried out oil-water separation through the oil-water separator to obtain valerian crude oil and water; ...
