Abstract
The invention discloses a method for preparing a fire-clearing capsule by combining MVR (mechanical vapor recompression) concentration and single-effect concentration. The fire-clearing capsule is prepared from folium isatidis, rheum officinale, gypsum and menthol. A preparation method of the fire-clearing capsule comprises the following steps: weighing raw material medicines according to a weight ratio for later use; crushing rheum officinale and gypsum into fine powder, and sieving for later use; adding water into folium isatidis, decocting for two times, decocting for 2 hours for the first time, and adding 10 times of water; the second time lasts for 1 hour, adding 8 times of water, mixing the decoctions, and filtering to obtain filtrate; performing MVR (mechanical vapor recompression) concentration and single-effect concentration on the filtrate to obtain clear paste with the relative density of 1.05-1.35 (60 DEG C); adding rhubarb and gypsumfine powder into the clear paste, uniformly mixing, and drying to obtain mixed powder; and dissolving menthol with ethanol, spraying the dissolved menthol into the mixed powder, and filling capsules. According to the method, the energy consumption cost in the extraction process can be reduced, the quality of effective components in the traditional Chinese medicine extract can be guaranteed, the energy-saving effect is remarkable, and the method has a wide application prospect in production.
