Description

Technical Field

[0001] The utility model relates to the technical field of aromatic oil extraction, in particular to a plant aromatic oil extraction device. Background Art

[0002] Aroma oils, also known as plant essential oils, are extracted from the aromatic molecules secreted by plant cells. In the fragrance industry, they are also called essential oils. Aroma oils are products of plant metabolism. Secreted by the protoplasts of cells, they are mostly volatile and have a fragrant smell. They are used in various ways in daily life, and their efficacy varies depending on the usage. The extraction process of aromatic oils requires the use of an aromatic oil extraction device.

[0003] Existing aromatic oil extraction devices generally soak and rinse the raw materials for extracting aromatic oil, and then add them directly to the extraction tank for heating extraction. However, some raw materials are large in volume and cannot be completely extracted during the heating extraction process, resulting in insufficient volatilization of the essential oil in the raw materials, which in turn causes waste of raw materials and increased production costs.

[0004] Therefore, we propose a plant aromatic oil extraction device. Utility Model Content
