Description

Technical Field

[0001] The utility model belongs to the technical field of fractionation devices, and in particular relates to a low-pressure and low-temperature fractionation device for traditional Chinese medicine extracts. Background Art

[0002] Fractional distillation is a method of separating mixtures of different boiling points. No new substances are generated in the process, but the original substances are separated. It is a physical change. Fractional distillation is a process of heating a mixture and cooling it according to the different boiling points of the components in the mixture to separate them into relatively pure single substances.

[0003] The existing distillation device uses a vacuum pump to remove part of the air to reduce the pressure, thereby reducing the boiling point of water, and then distills and concentrates the extracts of Sophora flavescens. The distilled pure water is mixed with the upper essential oil and the concentrated Sophora flavescens extract. However, due to the low efficiency and slow mixing rate of the extracts of Sophora flavescens and other extracts during the distillation, concentration, and final mixing with the essential oil, the concentration of the final mixed Chinese herbal medicine extract may be low. After the extraction of the Chinese herbal medicine extract is completed, some Chinese herbal medicine extracts will accumulate on the inner wall of the concentration tank. If these Chinese herbal medicine extracts are not cleaned in time, they may form dirt on the tank wall and affect the fractionation. Therefore, a low-pressure and low-temperature fractionation device for Chinese herbal medicine extracts is needed to solve the above problems. Utility Model Content
