Description

Technical Field

[0001] The invention relates to the technical field of natural plant essential oil extraction equipment, in particular to a high-efficiency evaporation and continuous distillation device for eucalyptus crude oil. Background Art

[0002] In the field of natural plant essential oil production, extracting essential oils from natural spice plants is a crucial link. For a long time, traditional essential oil distillation extraction methods have mainly relied on manually operated distillation equipment. This artificial distillation method has many disadvantages, which seriously restricts production efficiency and product quality. In the actual production process, manual loading requires workers to carry the spice plant raw materials one by one and add them to the distillation equipment. This not only consumes a lot of manpower, but the operation process is easily prone to instability and unevenness of the loading amount due to human factors, affecting the consistency of the distillation effect. The unloading process is also cumbersome. Workers need to manually open the equipment to remove the residue after the distillation is completed. The labor intensity is high and the unloading efficiency is low. At the same time, there may be safety risks due to contact with high-temperature equipment. In addition, manual distillation is difficult to accurately control key parameters such as temperature and pressure during the distillation process, resulting in large fluctuations in the essential oil extraction rate, which is difficult to meet the needs of large-scale, high-quality production. With the continuous growth of market demand for natural plant essential oils and the increasing requirements for product quality stability, it is urgent to develop an efficient, stable and highly automated essential oil distillation and extraction system. Based on this, a high-efficiency evaporation continuous distillation device for eucalyptus crude oil was designed, which integrates automated loading, feeding, discharging, distillation, condensation and other functions. Through automated control technology, precise control and continuous operation of the production process are achieved. Summary of the Invention
