Problems solved by technology

At present, the use of steam distillation to extract plant essential oils often faces the problem of low extraction efficiency of essential oil components. The main reasons are: (1) Incomplete extraction of raw materials, resulting in a high residual rate of essential oils in plant materials; (2) Steam condensation ability Insufficient, resulting in the loss of essential oil with gas phase leakage; (3) The large amount of distillation condensate, resulting in a large amount of essential oil dissolved in aromatic water and difficult to recover
The process of increasing the amount of steam or prolonging the distillation time can overcome the problem of incomplete extraction of raw materials, but it will further increase the output of condensate, which will cause more essential oils to dissolve in the water phase and cause losses; in addition, such Operation will also greatly increase energy consumption and reduce production capacity, so there are major limitations
