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 purslane 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] Freshly collected purslane medicinal materials are selected, washed with water to remove 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 this spray-drie...

Embodiment 2

[0013] Freshly collected purslane medicinal materials are selected, washed with water to remove sediment, pressed with a press to extract juice while fresh, and 5% by 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. Mix this spray-dried...

Abstract

The invention discloses freshly squeezed spray drying parslane herb granular decoction pieces and a preparation process thereof. The process is characterized by harvesting the medicinal material parslane herb, then cleaning, selecting and drip-washing parslane herb, squeezing parslane herb while parslane herb is fresh and taking the juice after filtration; adding water to the dregs, stirring the dregs and carrying out filtering and squeezing; mixing the obtained juice and then carrying out vacuum concentration, carrying out spray drying, collecting a spray-dried product, grinding the spray-dried product, mixing the powder with the juice obtained after primary squeezing, granulating the mixture and carrying out vacuum packaging after granule straightening. The parslane herb granular decoction pieces prepared by the method furthest retain the polar and nonpolar active ingredients in the medicinal material, have good flowability, are easy to store and transport and convenient to regulate, are controllable in quality, have reliable curative effects and have great significance in guaranteeing the clinical effects of traditional Chinese medicines. Popularization and implementation of the method has remarkable social significance and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology of decoction pieces of purslane, a traditional Chinese medicine. Background technique [0002] Purslane, a traditional Chinese medicine, is a plant of the family Portulaca oleracea Portulacaoleracea Dry aerial parts of L. This product has the functions of clearing away heat and detoxification, dispersing blood and reducing swelling. Clinically, it is mainly used to treat dysentery with pus and blood, hot stranguria, stranguria with blood, leukorrhea, carbuncle, malignant sore, erysipelas, etc. [0003] Commonly used purslane decoction pieces are processed as follows: after harvesting, impurities are removed, dried in the sun, and then packaged for storage and transportation. Such herbal decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, wh...
