Embodiment 1

[0012] The freshly collected plantain herbs are selected, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. 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 3 concoctions were combined 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 was 1.15, the extract was frozen in a -80°C refrigerator for 6 hours. Take out the east knot, freeze-dry, the pressure is 0.09Mpa, the temperature is -20 ℃, dry for 24 hours. Take out the freeze-dried product, crush it at low temperature, pass through an 80-mesh sieve, the moisture content is not higher than 12%, pack it into a bag, 1kg / bag, add the bagged antioxid...

Embodiment 2

[0014] The freshly collected plantain herbs are selected, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. 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 3 concoctions were combined and filtered with an 80-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 was 1.10, the extract was frozen in a -80°C refrigerator for 8 hours. Take out the east knot, freeze-dry, the pressure is 0.08Mpa, the temperature is -40 ℃, dry for 48 hours. Take out the freeze-dried product, crush it at low temperature, pass through a 60-mesh sieve, the moisture content is not higher than 12%, bag it, 1kg / bag, add the bagged antioxidant and desic...

Abstract

The invention discloses a plantain-herb freshly-squeezed freeze-dried powder decoction piece and a preparing technology thereof. The preparing technology includes the steps that a plantain-herb medicinal material is harvested to be cleanly selected, leached and squeezed while the plantain-herb medicinal material is fresh, and medicinal juice is filtered; the medicinal dregs are stirred by adding water, filtered and squeezed; the obtained medicinal juice is combined to be subjected to pressure reducing concentration and freeze drying, and the freeze-dried product is collected and smashed to be subjected to vacuum package. By means of the plantain-herb powder decoction piece prepared with the method, polar effective constituents and non-polar effective constituents in the medicinal material are furthest and simultaneously reserved; the decoction piece is beneficial to storage and transport, convenient to regulate, controllable in quality and reliable in curative effect and is of great significance in guaranteeing the traditional-Chinese-medicine clinical effect. The method is applied and popularized, and the remarkable social meanings and remarkable economic benefits are achieved.

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 Chinese medicinal plantain. Background technique [0002] Plantago Plantaginaceae Plantago asiatica L. or flat car front Plantago depressa Dried whole herb of Willd. This product has the effects of clearing heat and diuresis, eliminating phlegm, cooling blood and detoxifying. For hot stranguria astringent pain, edema oliguria, diarrhea due to heat-dampness, cough due to phlegm-heat, hematemesis and epistaxis, carbuncle sore and so on. [0003] The commonly used processing methods of plantain decoction pieces are: digging in summer, removing sediment, drying in the sun, and then packing 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, which is not conducive to formula a...
