Description

Cinnamomum camphora essential oil direct steam distillation pot

Technical Field

The invention relates to an extraction device for extracting plant essential oil, in particular to a camphor essential oil direct steam distillation pot.

Background

Steam distillation is the most commonly used separation method for extracting essential oils from plants. According to different contact modes of water and raw materials in a distillation kettle, the distillation kettle can be divided into three types, namely water distillation, water distillation and direct steam distillation. The prior camphor essential oil extraction mainly adopts an in-water distillation method and a direct steam distillation method. When the Cinnamomum camphora essential oil is extracted by distillation in water, water is added to immerse the material layer to make the water level higher than that of the raw material layer, and steam is used to directly or indirectly heat the bottom of the material layer. At the moment, the raw materials are completely soaked in water, the wetting and penetrating effects of the water are good, the heating is uniform, and the extraction yield of the camphor essential oil is high. However, the distillation in water process has a long production cycle per batch. Based on the production of 1 ton of cinnamomum camphora raw material in each tank, about 5.0 tons of water needs to be added, steam heating is adopted, oil production is started after about 3 hours, extraction can be completed after about 2.0 hours, the raw material filling and residue removal are carried out for about 1.0 hour, and the whole process needs 6 hours. The working time of one day is 12 hours, only 2 batches can be produced, and the production efficiency is low. Moreover, the production process has large investment of solvent, energy consumption, labor cost and the like, and the production cost is high. The distillation method in water is difficult to meet the requirements of concentrated, large-scale and rapid extraction of the cinnamomum camphora.

The direct steam distillation method is more suitable for the production mode of the cinnamomum camphora than the distillation in water. Weilinsheng et al (patent CN 201776140U) provide a device for extracting crude cinnamomum camphora oil, wherein an upper pot body is coaxially and hermetically connected with a lower pot body, a charging barrel is coaxially arranged in the lower pot body, and the lower end of the side wall of the lower pot body is respectively connected with a steam pipe and a microwave waveguide pipe; the invention has simple structure and convenient operation. However, the high-power microwave is added in the device, the device cannot be used in a mountain area with power shortage, and meanwhile, steam is easy to leak from the side wall; the trouble of charging and discharging slag by using the inner sleeve affects the working efficiency. In the production, a steam distillation device which is suitable for mountain land extraction, is convenient for loading and unloading slag and does not discharge waste water is needed, so that the steam distillation device can better adapt to the requirement of concentrated and rapid extraction of the cinnamomum camphora in mountain lands.
