Description

Technical Field

[0001] The invention belongs to the technical field of essential oil extraction, and relates to osmanthus essential oil extraction equipment, in particular to an osmanthus essential oil antioxidant continuous extraction device and method. Background Art

[0002] Sweet osmanthus, also known as sweet osmanthus and rock osmanthus, is an evergreen shrub or small tree of the Rhinoceros family. It is hard and thin-skinned, with oblong leaves with pointed ends, opposite, and do not wither in winter. The flowers grow between the leaf fusci, and the corolla is fused with four petals and small in shape. Its varieties include golden osmanthus, silver osmanthus, red osmanthus, and bay laurel. Sweet osmanthus is one of the ten traditional Chinese flowers and an excellent garden tree species that combines greening, beautification, and fragrance for both ornamental and practical purposes. The fragrance of osmanthus is so pure that it can dispel dust and so strong that it can overflow far, which is a unique feature, especially in mid-autumn season, when the osmanthus clusters are in full bloom and the moon is full in the quiet night, people drink wine and appreciate the osmanthus, the fragrance is so strong that they can make people feel refreshed. Among the ancient Chinese poems and lyrics about flowers, the number of works about osmanthus is also quite considerable. It has been deeply loved by the Chinese since ancient times and is regarded as a traditional famous flower.

[0003] The main extraction method of osmanthus essential oil is distillation. The existing distiller for extracting osmanthus essential oil is relatively simple in structure. Generally, osmanthus essential oil is extracted only by water vapor, and the extraction takes a long time. Therefore, the distillation is basically followed by pressing to accelerate the extraction of essential oil. However, after the osmanthus raw material is pressed by a pressing plate, the osmanthus is easily adhered and accumulated in the air holes of the placement plate after being squeezed, which easily affects the extraction work. In addition, a part of the osmanthus material will remain on the lower surface of the pressing plate. In order not to affect the subsequent extraction efficiency, the extraction needs to be interrupted and sorted first, which reduces the extraction efficiency. Summary of the invention
