Abstract

The invention discloses a preparation method for active dendrobium candidum superfine powder. The preparation method comprises steps: first, leaves of harvested fresh dendrobium candidum are removed, and washing and draining are carried out; second, punching is carried out, the dendrobium officinale is fixed on a die, the die is placed on a shelf of a vacuum drying container, cooling is carried out, the die is a cube-shaped metal die body (1) with an upper surface equipped with a half-cylindrical groove (2), and small holes (3) are arranged in the die body; third, vacuum-pumping is carried out; fourth, the shelf is heated, the temperature is risen to 0 DEG C, the pressure intensity is kept at 20-100Pa, drying is carried out, the material temperature is risen from 0 DEG C to 20 DEG C, the pressure intensity is kept at 10-20Pa, drying is carried out, the material temperature is risen from 20 DEG C to 40 DEG C, the pressure intensity is kept within 10Pa, drying is carried out, pressurization to a normal pressure is carried out; fifth, low temperature air-flow crushing is carried out, and active dendrobium candidum superfine powder is obtained and more than 95% of active dendrobium candidum superfine powder has a particle size of being less than 20 micrometers. The freeze-drying rate is high, freeze-drying time is saved, energy consumption is lowered, the product has a small particle size and is easy to dissolve and absorb, and the bioavailability is high.

Description

technical field [0001] The invention relates to a method for freeze-drying dendrobium officinale, in particular to a preparation method of active dendrobium officinale superfine powder. Background technique [0002] Dendrobium officinale Kimura et Migo is the dry stem of Dendrobium officinale Kimura et Migo, named for its iron-green skin. Dendrobium plants can be divided into dozens of varieties such as Tiepi, Nobile, Huoshan, Huangcao, Huancao, and Horsewhip according to their shape and origin. Among them, Dendrobium candidum is the most precious. Wild Dendrobium officinale grows on semi-shady rocks and bark in mountains at an altitude of 100-3000m. It likes warm and humid climates and semi-shady environments, and is not cold-resistant. The fresh stems of Dendrobium candidum can be eaten directly, or stewed, or made into tea, or soaked in wine, and are usually processed into dry products, such as Tiepi Fengdou. Dendrobium candidum has good medicinal value and health care ...
