Description

Technical Field

[0001] The utility model belongs to the field of Chinese patent medicine production equipment, and specifically relates to an extract concentration device. Background Art

[0002] In the prior art, there are various ways to concentrate Chinese herbal medicine extracts, including conventional compression evaporation, which is mostly used for evaporation of non-thermosensitive drugs, and reduced pressure evaporation, which is mostly used for evaporation of heat-sensitive drug components. The evaporation speed is fast, the heating time is short, it is not affected by the static pressure of the liquid, and the drug components are not easily destroyed. It is multi-effect evaporation, that is, in an appropriate environment, the drug is extracted and concentrated under constant temperature conditions. Heating evaporation concentration is the most common way to concentrate the extract, and the extract is heated to evaporate the excess water in the extract to achieve the purpose of concentration;

[0003] There are various extract concentration devices in the prior art. Generally, the extract in the concentration tank is heated and concentrated. The water vapor generated by the extraction is not recycled, resulting in a waste of resources and possible environmental pollution.
