Efficient environment-friendly plant essence extraction method

The invention discloses a high-efficiency environment-friendly plant essence extraction method which comprises the following steps: blowing: generating airflow by an axial flow fan, injecting heated air in a heating box into a water tank, and blowing the heated air to plants on the surface of a placement plate through vent holes, and drying: water in the plants flows along with the hot air, and air enters a drying box, so that the plants are dried; the heating plates are used for heating air blown into the heating box by the axial flow fan, the air flow flows along the heating plates distributed in a staggered mode, the heating time is prolonged, the heating efficiency is effectively improved, hot air is evenly blown upwards after entering the air flow dividing box, and therefore the air flow is uniform and uniform. The plant drying device is simple in structure, plants placed on the storage plate are dried, moisture in the plants is removed, the content of moisture in the plants is reduced, the proportion of
