A kind of preparation method of dendrobium officinale

Abstract

The invention discloses a preparation method of Dendrobium officinale, comprising the steps of: 1) laying the selected Dendrobium officinale on a first bracket for baking, the baking temperature is 50-80°C, and the baking time is 30-60°C; minutes; 2) the baked Dendrobium candidum is placed on the second support for drying. It can be seen from the above technical scheme that since the temperatures of the two baking times are relatively low, the nutrient content of Dendrobium officinale can be guaranteed on the basis of effectively removing water. It can be seen from the above technical scheme that in the preparation method of Dendrobium candidum provided by the present invention, most of the water is firstly baked by 50-80°C to remove most of the water, and then dried. The roasting method, because the temperature of the two roasts is relatively low, will not destroy the nutritional components of Dendrobium candidum, and can ensure the nutritional components of Dendrobium candidum on the basis of effectively removing water.

Description

technical field [0001] The invention relates to the technical field of medicinal material processing, in particular to a preparation method of Dendrobium officinale. Background technique [0002] Dendrobium candidum, also known as black knot grass or Yunnan candidum, belongs to the perennial epiphytic herb of the Orchidaceae of the order Microzoa, the stem is erect, cylindrical, 9-35cm long, 2-4mm thick, the sepals and petals are yellow-green, oblong-lanceolate Shape, about 1.8cm long, about 4-5mm wide, its stem is used as medicine, belongs to the yin-tonifying medicine in tonic medicine, nourishes the stomach and promotes body fluid, nourishes yin and clears away heat. [0003] In order to facilitate the consumption of Dendrobium candidum, it is usually mixed with ingredients for processing and eaten, or boiled water for drinking as tea. During the processing of Dendrobium candidum, the water in Dendrobium candidum should be removed, but the active ingredients should be pre...

AI Technical Summary

Problems solved by technology

[0004] The processing technology of Dendrobium candidum in the prior art is as follows: cut Dendrobium candidum into small sections, and then bake at high temperature after the cutting is completed, until it is dried. There are many areas exposed to high temperature, and a lot of nutrients will be taken away during the process of water evaporation, resulting in the loss of nutrients
