Description

Technical Field

[0001] This utility model relates to the field of essential oil extraction technology, and in particular to a plant essential oil extraction, separation and distillation apparatus. Background Technology

[0002] Plant essential oil extraction and separation distillation equipment plays a vital role in modern applications. With the increasing demand for natural and healthy products, plant essential oils have garnered significant attention due to their unique aromas and various health benefits. Traditional extraction methods are inefficient and may damage the essential oil components. Distillation equipment, on the other hand, can efficiently separate the essential oil components from plants. It utilizes the principle of different boiling points, heating the essential oils to vaporize them, followed by cooling and condensation to achieve separation. This equipment can process a wide variety of plant materials, from common flowers like roses and lavender to herbs. In the fields of cosmetics, aromatherapy, and food additives, there is a huge demand for high-quality plant essential oils, and distillation equipment provides a reliable means to meet this demand, thus driving the development of related industries.

[0003] For example, patent CN218146545U discloses a plant essential oil processing, separation, and extraction device. This utility model provides a plant essential oil processing, separation, and extraction device that facilitates the cleaning of plants after steaming or boiling. This utility model provides such a plant essential oil processing, separation, and extraction device, including: a base plate, with a support frame fixedly installed on the top left side of the base plate and a similar support frame fixedly installed on the top right side of the base plate; a distillation tank, with a distillation tank fixedly installed on the left side of the left support frame; a water pump, with a water pump fixedly installed on the left side of the middle of the distillation tank and connected to the distillation tank; and a steaming tray, with a steaming tray fixedly installed inside the distillation tank for placing plants. The water vapor is cooled by cold water inside the tank, forming water droplets that fall into the essential oil container for collection. The steaming tray helps separate the plants from the water, facilitating cleaning by workers.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: In a current plant essential oil processing and separation extraction device, the distillation tank has only one steamer. After the plant raw material is placed in the distillation tank for distillation, the distilled plant raw material needs to be cleaned out and then new plant raw material needs to be loaded for distillation, resulting in low distillation efficiency. Furthermore, when extracting plant essential oils using steam distillation, the water in the distillation tank will continuously decrease as the water evaporates. When directly adding cold water to the distillation tank, the cold water needs to be reheated, which reduces the efficiency of essential oil extraction and makes it inconvenient to recycle the water. Therefore, there is room for improvement. To address these issues, we designed a plant essential oil extraction and separation distillation device to provide an alternative technical solution.
