Problems solved by technology

Due to the time-consuming and energy-consuming extraction during the preparation of granule decoction pieces, and because water is often used as a solvent, it is difficult to extract the non-polar active ingredients in the medicinal materials
In addition, since the medicinal material of bamboo leaves used for extraction is also dried and stored for a long time, it is difficult to avoid the situation that its raw materials are easy to be polluted and mildewed

Embodiment 1

[0012] Freshly collected herbal medicines of the bamboo leaves, cleanly selected, washed, cut into 1cm sections, added with water 0.5 times the weight of the medicinal materials, stirred for 15 minutes, squeezed while fresh, and reserved 0.1% of the virgin juice for later use. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times of medicinal juice of bamboo leaves, filter through a 60-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 60°C. When the relative density of the obtained concentrated liquid is 1.03, it is transferred to a spray drying tower for spray drying. The temperature of the air inlet is set at 140°C, and the temperature of the air outlet is set at 110°C. The dried matter is collected, pulv...

Embodiment 2

[0014] Clean the freshly collected herbal medicine of Pachyphyllum edulis, wash it, cut it into 2cm sections, add 1 times the weight of the medicinal material in water, stir for 30 minutes, squeeze it while it is fresh, and save 0.3% of the virgin juice for later use. Add 5 times the amount of tap water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times of medicinal juice of bamboo leaves, filter through a 100-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature to 70°C. When the relative density of the obtained concentrated solution is 1.05, it is transferred to a spray drying tower for spray drying. The temperature of the air inlet is set at 120° C., and the temperature of the air outlet is set at 90° C. The dried matter is collected, pulverized, and pa...

Abstract

The invention discloses a process for preparing freshly-squeezed lophatherum gracile spray-dried granular medicinal slices. The process comprises the following steps: harvesting lophatherum gracile medicinal materials, selecting, rinsing, squeezing while being fresh, and filtering the decoction; adding water into the decoction for stirring, and filtering and squeezing; and mixing the obtained decoction, performing vacuum concentration, performing spray drying, and preparing into granules. According to the lophatherum gracile granular medicinal slices prepared by the method, the liquidity is high, and polar and non-polar active ingredients in the medicinal materials are simultaneously remained to the greatest degree. The medicinal slices are convenient to transport and store, convenient to mix, controllable in quality and reliable in curative effects, and have significances for ensuring clinical curative effects of traditional Chinese medicine. The method is popularized and implemented to achieve obvious social significances and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing traditional Chinese medicinal materials, and in particular relates to a processing technology of decoction pieces of traditional Chinese medicine Danzhu leaves. Background technique [0002] The traditional Chinese medicine Pachyphyllum is a perennial herb of the Poaceae Pachyphyllum genus. It has the effects of cooling, antipyretic, diuretic and inducing labor. Clinical indications: fever in the chest, coughing up qi, hematemesis, heat-toxin wind, relieving thirst, suppressing alchemy and stone poison, eliminating phlegm, treating mania and depression, apoplexy due to apoplexy, headache and wind, relieving palpitations, etc. [0003] The commonly used processing method of decoction pieces of light bamboo leaves is as follows: after harvesting, impurities are removed, dried in the sun, directly packaged for storage and transported. The hygienic indicators of these dry bamboo leaves cannot meet the stand...
