Problems solved by technology

The preparation process of granular decoction pieces, the extraction is not only time-consuming and energy-consuming, but also because a large amount of 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 paulownia flower medicinal material used for extraction is also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0011] The freshly collected paulownia flower medicinal materials are cleaned, washed with water to remove the sediment, pressed with a press to extract juice while fresh, and 1% by weight of the virgin medicinal juice is reserved for another use. Add 3 times the amount of tap water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned remaining first-pressed medicinal juice is combined with the subsequent two squeezed medicinal juices, and filtered with a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 65 °C. When the relative density of the concentrated extract is 1.05, it is spray-dried, the air inlet temperature is 140°C, and the air outlet temperature is 100°C. The spray-dried matter is collected, crushed at low temperature, and passed through an 80-mesh sieve. Mix ...

Embodiment 2

[0013] The freshly collected paulownia flower medicinal materials are cleaned, washed with water to remove the sediment, pressed with a press to extract juice while fresh, and 5% of the weight of the virgin medicinal juice is reserved for another 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 remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned remaining first-pressed medicinal juice is combined with the subsequent two squeezed medicinal juices, and filtered with a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 70 °C. When the relative density of the concentrated extract is 1.10, it is spray-dried, the air inlet temperature is 120°C, and the air outlet temperature is 90°C. The spray-dried matter is collected, crushed at low temperature, and passed through an 80-mesh sieve. M...

Abstract

The invention discloses a freshly-squeezed paulownia flower spray-dried granular decoction piece and a preparation technology thereof. The preparation technology comprises the following steps: after the paulownia flowers are harvested, picking qualified paulownia flowers, washing selected paulownia flowers, squeezing the fresh paulownia flowers, filtering the juice, adding water into the residues, filtering, squeezing; merging the juice, carrying out reduced pressured concentration, spray-drying the liquid, collecting the spray-drying product, grinding the collected solids, mixing the grinded solids with primarily-squeezed juice, carrying out granulation, finishing, and packaging the granules into vacuum bags. The provided preparation method maximally preserves the polar and non-polar effective components in paulownia flowers. The decoction piece has good fluidity, and is convenient for transportation, storage, and blending, the quality is controllable, and the curative effect is reliable. The preparation technology has an important meaning for ensuring the clinical curative effect of traditional Chinese medicine. The provided decoction piece can generate prominent social benefits 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 paulownia flower of traditional Chinese medicine. Background technique [0002] The traditional Chinese medicine Paulownia Paulowniatomentosa (Thunb.) Steud.'s flower. This taste is bitter and cold, and has the effect of clearing away heat and detoxification. It is mainly used for the treatment of cough due to lung heat, bacillary dysentery, and bronchitis. [0003] The commonly used processing method of paulownia flower decoction pieces is: harvest when the flowers bloom in summer, dry, and pack for storage and transportation. Such decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, which is not conducive to formula adjustment and clinical efficacy, and even brings hidden harm to patients. [0004] At pre...
