Method for preparing aquilaria essential oil

Abstract

The invention discloses a method for preparing the aquilaria essential oil, and belongs to the technical field of manufacturing and extracting essential oils, which comprises a steam distillation column and a vacuum control distillation column. The feed port of the steam distillation column is connected with crushed agarwood and water. The reaction discharging port of the steam distillation column is connected with an oil-water separator. The distilled water and the distilled oil are separated. The distilled water is circularly fed into the steam distillation column and the distilled oil is fed into the vacuum control distillation column. The distillation column of the vacuum control distillation column is placed in a heating jacket and two pipes are led out of the pylon of the column, wherein the lower pipe serves as an essential oil outflow pipe and the upper pipe serves as a vacuum control pipe. A set of condensers is arranged between the ports of the two pipes. The vacuum control pipe is provided with a vacuum valve and the end portion thereof is connected with a vacuum device. A condenser is arranged in the essential oil outflow pipe. According to the invention, the vacuum distillation technology is combined with the vapor distillation technology, so that the refined aquilaria essential oil can be extracted. The extraction time is greatly shortened and the thermal stability of the extraction process is ensured. The components of the essential oil are less susceptible to damage and volatile loss, and the flowability of the aquilaria essential oil is improved. Meanwhile, the product quality of the aquilaria essential oil is improved.

AI Technical Summary

Benefits of technology

This new technique combines two methods: one uses heat for extracting crude oils from mushroom roots while another involves evacuating them under reduced pressure or by adding steam beforehand. These techniques help reduce damage caused by excessive temperature exposure on the extracted material without affecting its flavor or taste qualities.

Problems solved by technology

This patented technical problem addressed by this patents relates to how to make an herbal medicine that helps calm down breathing difficulties caused by air pollution or stressing neurology patients while still having its beneficial effects.
