Flower essential oil distillation extraction method

The invention relates to a flower essential oil distillation extraction method, which comprises: S1, a crushing step, namely a step of mixing fresh petals and distilled water, crushing the mixture, and uniformly stirring the mixture to obtain a crushed mixed solution; S2, a wall breaking step, namely a step of transferring the crushed mixed solution into a steam explosion device, introducing nitrogen to a certain pressure, introducing steam until a wall breaking pressure, maintaining the pressure for a period of time, opening a discharge valve, and carrying out reduced pressure release to obtain a wall-broken mixed solution; S3, a distillation step, namely a step of carrying out steam distillation on the wall-broken mixed solution in a distillation tank to obtain mixed steam; and S4, an oil-water separation step, namely a step of sequentially carrying out condensation, oil-water separation and dehydration on the mixed steam to prepare the essential oil.
