Embodiment 1

[0012] The freshly collected mint medicinal materials are cleaned, rinsed with water, squeezed with a press while fresh, and extracted for juice. 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 into medicinal juice with a press. The above-mentioned 3 medicinal juices were combined, concentrated under reduced pressure, and the temperature was set at 65°C. When the relative density of the concentrated solution is 1.10, transfer to -20°C refrigerator and freeze for 12 hours. The frozen matter was taken out and freeze-dried at a temperature of -20°C and a pressure of 0.08Mpa for 48 hours. Take out the lyophilized substance, pulverize it, and pass through a 60-mesh sieve. In addition, the mint condensed water collected during concentration under reduced pressure was added with 5% NaCl by weight and stirred to dissolve. The solut...

Embodiment 2

[0014] The freshly collected mint medicinal materials are cleaned, rinsed with water, squeezed with a press while fresh, and extracted for juice. 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 into medicinal juice with a press. The above-mentioned 3 medicinal juices were combined, concentrated under reduced pressure, and the temperature was set at 70°C. When the relative density of the concentrated solution is 1.15, transfer to -20°C refrigerator and freeze for 10 hours. The frozen matter was taken out and freeze-dried at a temperature of -40°C and a pressure of 0.07Mpa for 24 hours. Take out the lyophilized substance, pulverize it, and pass through a 60-mesh sieve. In addition, the mint condensed water collected during concentration under reduced pressure was added with 3% NaCl by weight, and stirred to dissolve. The solution was p...

Abstract

The invention discloses freshly squeezed freeze drying peppermint powdery decoction pieces and a preparation process thereof. The process is characterized by harvesting the medicinal material peppermint, then cleaning, selecting and drip-washing peppermint, squeezing peppermint while peppermint 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 freeze drying, besides, separating essential oil from concentrated condensate, mixing the essential oil with a freeze-dried product, sieving the mixture and bagging the products. The peppermint powdery decoction pieces prepared by the method furthest retain the active ingredients in the medicinal material, 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.
