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 patchouli medicinal materials used for extraction are also dried and stored for a long time, it is difficult to avoid the situation that the raw materials are easy to be polluted and mildewed

Embodiment 1

[0012] Freshly collected patchouli medicinal materials, cleaned, washed, cut into 1cm segments, 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 medicinal 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. The above-mentioned 3 times of patchouli medicinal juices were combined, filtered through a 60-mesh sieve, the filtrate was concentrated under reduced pressure, and the temperature was set 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, ...

Embodiment 2

[0014] Freshly collected patchouli herbs, cleaned, washed, cut into 2cm segments, added with water equal to the weight of the herbs, stirred for 30 minutes, squeezed while fresh, and reserved 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. The above-mentioned 3 patchouli medicinal juices were combined, filtered through 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 obtained concentrated liquid 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 passed through a 60-mesh sieve. Spray the...

Abstract

The invention discloses a preparation process of a freshly-squeezed herba pogostemonis spray drying particle decoction piece. The process comprises the following steps: harvesting herba pogostemonis, carrying out cleaning, selecting and drip washing, immediately squeezing herba pogostemonis, and filtering, so as to obtain medicine juice; and adding water into medicine residue, stirring, filtering, and squeezing; and combining the obtained medicine juices, carrying out reduced pressure concentration and spray drying, and then preparing particles. The herba pogostemonis spray drying particle decoction piece prepared by virtue of the preparation process has good fluidity, and the polar and non-polar effective components in the medical material are furthest simultaneously preserved; and the decoction piece is suitable for being stored and transported, convenient to blend, controllable in quality and reliable in treatment effect and has very important significance to the clinical treatment effects of traditional Chinese medicines. By popularizing and implementing the preparation process, remarkable social and economic benefits can be created.

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 Chinese medicinal patchouli. Background technique [0002] The traditional Chinese medicine Patchouli is the Lamiaceae plant Pogostemon cablin (Blanco) Benth. The dry aerial part. It has the effects of aromatizing turbidity, harmonizing and stopping vomiting, and relieving heat. It is mainly used to treat dampness and turbidity in the middle, nausea and vomiting, summer-dampness syndrome, early onset of dampness and temperature, fever and fatigue, chest tightness and discomfort, cold-damp blocking heat, Abdominal pain, vomiting and diarrhea, nasal sinusitis headache. [0003] The commonly used processing methods of patchouli decoction pieces are: after harvesting, remove impurities, dry in the sun, and pack directly for storage and transportation. The hygienic indicators of these dried ...
