Embodiment 1

[0022] Put the fresh strips of Dendrobium officinale into water, clean them, dry them and cut them into small sections of Dendrobium officinale with a length of 0.1cm; put the cut short sections of Dendrobium officinale into 5L liquid nitrogen tanks and freeze them for 20 minutes; Pre-cooling for 5 minutes; freeze the frozen Dendrobium candidum segments in a freezer grinder for 30 minutes, and re-add liquid nitrogen every 4 minutes to keep Dendrobium candidum in a wet state with liquid nitrogen to obtain fresh powder of Dendrobium candidum; As for the fresh powder of Dendrobium candidum in the freeze dryer, the temperature of the low-temperature drying chamber is lowered to -40°C, and then vacuumized until the vacuum pressure drops to 15Pa. The freeze dryer here preferably adopts a vacuum dryer; when the vacuum pressure drops to 15Pa , the temperature of the low-temperature drying chamber was raised to 20° C., and the vacuum was pumped for 10 hours; the dried powder was sterili...

Embodiment 2

[0024] Put the fresh strips of Dendrobium officinale into water, clean them, dry them and cut them into small pieces of Dendrobium officinale with a length of 0.5cm; put the cut pieces of Dendrobium officinale into 10L liquid nitrogen tanks and freeze them for 40 minutes; Pre-cooling for 10 minutes; freezing and grinding the Dendrobium candidum subsections after liquid nitrogen freezing in a freezer grinder for 50 minutes, and adding liquid nitrogen every 6 minutes to keep the Dendrobium candidum in a wet state with liquid nitrogen all the time to obtain fresh powder of Dendrobium candidum; As for the fresh powder of Dendrobium candidum in the freeze dryer, the temperature of the low-temperature drying chamber is lowered to -50°C, and then vacuumized until the vacuum pressure drops to 20Pa. The freeze dryer here preferably adopts a vacuum dryer; when the vacuum pressure drops to 20Pa , the temperature of the low-temperature drying chamber was raised to 30° C., and the vacuum wa...

Embodiment 3

[0026] Put the fresh strips of Dendrobium candidum into water, clean them, dry them and cut them into small pieces of Dendrobium candidum with a length of 0.3cm; put the cut pieces of Dendrobium candidum into 8L liquid nitrogen tanks and freeze them for 30min; Pre-cooling for 8 minutes; freeze the frozen Dendrobium candidum segments in a freezer grinder for 40 minutes, and re-add liquid nitrogen every 5 minutes to keep Dendrobium candidum in a wet state with liquid nitrogen all the time to obtain fresh powder of Dendrobium candidum; As for the fresh powder of Dendrobium candidum in the freeze dryer, the temperature of the low-temperature drying chamber is lowered to -45°C, and then vacuumized until the vacuum pressure drops to 18Pa. The freeze dryer here preferably adopts a vacuum dryer; when the vacuum pressure drops to 18Pa , the temperature of the low-temperature drying chamber was raised to 25° C., and the vacuum was pumped for 12 hours; the dried powder was sterilized unde...

Abstract

The invention belongs to the technical field of preparation of Chinese herbal medicines, in particular relates to a preparation method of dendrobium officinale and more particularly relates to a preparation method of dendrobium officinale super-micropowder. The preparation method can be used for overcoming the defects that the traditional dendrobium officinale finished-product is low in solubility and absorbance. The preparation method of the dendrobium officinale supper-micropowder comprises the following steps of: washing, cutting, liquid nitrogen freezing, refrigerative grinding, processing by using a freezer dryer, sterilizing, weighing, packaging and the like. The preparation method of the dendrobium officinale supper-micropowder is reasonable in design and simple in step; and the dendrobium officinale super-micropowder prepared by using the preparation method can be used for improving dissolving-out degree of effective ingredients and is beneficial to human body absorption and increase of bioavailability.

Description

technical field [0001] The invention belongs to the technical field of preparation of Chinese herbal medicines, and relates to a preparation method of dendrobium officinale, in particular to a preparation method of superfine powder of dendrobium officinale. Background technique [0002] Dendrobium officinale belongs to the perennial herbaceous plant of Orchidaceae. It is a precious medicinal plant resource. It contains polysaccharides, stilbenes, alkaloids, amino acids and trace elements. Anti-fatigue, hypoglycemic, body fluid and other biological activities. Wild Dendrobium candidum is generally born in mountains at an altitude of about 1600 meters, and the climate is warm and humid and half shade and half sun. Wild Dendrobium candidum is distributed in East Asia, Southeast Asia, Australia and other countries and regions; in China, it is mainly distributed in Anhui, Zhejiang, Yunnan, Guangxi, Hunan, Guizhou and other places. Dendrobium candidum has been artificially culti...
