The invention relates to the technical field of
medicine extraction, and discloses a vacuum low-temperature
distillation herbal
medicine bath fine extraction process, which comprises the following steps: 1, pretreating raw materials; step 2, crushing and mixing; step 3, vacuum low-temperature
distillation; step 4, filtering treatment; step 5, concentrating and
drying; and step 6, carrying out post-treatment on the extract. According to the vacuum low-temperature
distillation herbal
medicine bath fine extraction process, the vacuum low-temperature distillation condition is accurately controlled, so that the heat-sensitive component
retention rate is greatly increased, and the medicated bath effect is enhanced; in the aspect of
impurity removal, various filtering and
chromatography technologies are cooperated, so that the
impurity content is greatly reduced, and the use safety is guaranteed; in terms of
energy consumption, low-temperature and low-pressure operation achieves great
energy conservation, and large-scale production is facilitated; after the extraction process is optimized, by means of
microwave,
superfine grinding, ultrasonic mixing and the like, the
utilization rate of the herbal medicine is remarkably increased, high-quality, high-efficiency and high-safety innovation breakthrough is brought to the herbal medicine medicated bath industry, and the method has great market competitiveness and application and popularization value.
