In the inclusion process, inclusion agents with different dosages can be added according to different collection conditions, so that the components of the volatile oil inclusion compound prepared by the technical scheme are optimal when the total dosage of the inclusion agents is constant.
Specifically, when the volatile oil inclusion compound preparation device of the present embodiment is used, the medicinal materials are put into the extraction tank 10, and steam is introduced into the extraction tank 10 for distillation, the steam drives the volatile oil and the aromatic water in the extraction tank 10 to enter the condenser 20 for condensation, and the condensed volatile oil and aromatic water enter the first oil-water separator 30; after the first oil-water separator 30 collects the volatile oil and the aromatic water with specified amounts, the condenser 20 is switched to be communicated with the second oil-water separator 30 to collect the volatile oil and the aromatic water; after the second oil-water separator 30 collects the volatile oil and the aromatic water with specified amounts, the condenser 20 is switched to be communicated with the third oil-water separator 30 to collect the volatile oil and the aromatic water; repeating the collecting steps until a preset Nth oil-water separator 30 participates in the collection of the volatile oil and the aromatic water, and when the volatile oil and the aromatic water are collected by a third oil-water separator 30, communicating the first oil-water separator 30 with an inclusion mechanism 40, and putting a first-stage inclusion agent for first-stage inclusion; after the first-stage inclusion is finished, the inclusion mechanism 40 is switched to be communicated with the second oil-water separator 30, and a second-stage inclusion agent is added for second-stage inclusion; after the second-stage inclusion is finished, switching the inclusion mechanism 40 to be communicated with a third oil-water separator 30, and adding a third-stage inclusion agent for third-stage inclusion; repeating the clathrating steps until the preset Nth-level clathration is finished; therefore, the volatile oil inclusion compound preparation device of the embodiment carries out seamless volatile oil collection work by arranging at least three oil-water separators 30, when the third oil-water separator 30 collects volatile oil and aromatic water, the first oil-water separator 30 finishes oil-water separation, and can be communicated with the inclusion mechanism 40 for inclusion process, so that the oil collection efficiency is greatly improved, the collection work can be simultaneously carried out in the inclusion process, the production efficiency is improved, and the loss of the volatile oil is avoided.

The intermediate product after each stage of mixing is collected by the holding tank 140. Taking this embodiment as an example, since there are three oil water separators 30, i.e. three-stage collection and three-stage subsequent processes are performed, this embodiment requires three temporary storage tanks 140 for collecting the intermediate products collected by the first stage, the second stage and the third stage, respectively, and after the three stages are all collected, the intermediate products of the first stage, the second stage and the third stage are all re-fed into the mixing mechanism 100 for total mixing of the clathrate, so as to form the final clathrate product for the next preparation.

In another embodiment, when the total amount of inclusion agent to be added is uncertain or definite, the inclusion agent may be added in stages such that when the amount of the first-stage inclusion agent to be added is a, the amount of the mth-stage inclusion agent to be added is in the range of a/(m +1) to a/m, where m.gtoreq.1.
Since the first discharge port 31 and the second discharge port 32 are provided in the present embodiment, excess liquid can be recovered before inclusion. When the density of the volatile oil is greater than that of the water, before the oil-water separators 30 are communicated with the inclusion mechanism 40, a second discharge pipeline can be selectively opened, so that a second discharge port 32 is communicated with the extraction tank 10, and redundant water is discharged; or, when the density of the volatile oil is less than that of the water, before the oil-water separators 30 are communicated with the inclusion mechanism 40, the first discharge pipeline can be selectively opened to enable the first discharge port 31 to be communicated with the extraction tank 10, so as to discharge the excessive water.

Specifically, in the present embodiment, the first oil-water separator 30 is a container for collecting the first oil-water separation, and since the concentration of the volatile oil in the first oil-water separation is high and the amount of the excess liquid is small, the excess liquid is not recovered before the inclusion, but the collected volatile oil and the oil-water mixture are directly transferred to the inclusion mechanism 40 for inclusion after the collection. When the volatile oil and the aromatic water are collected by the second oil-water separator 30 and the third oil-water separator 30, the concentration of the volatile oil is lower than that of the volatile oil collected by the first stage, so that after standing and layering, the redundant water is introduced into the extraction tank 10 for recovery by opening the first discharge port 31 or the second discharge port 32, so as to improve the yield of the volatile oil of the stage.
