Abstract

The invention discloses a preparation method of active dendrobium candidum superfine powder, which comprises the following steps: 1) removing leaves from freshly harvested dendrobium candidum, washing and draining; 2) punching holes, fixing them on a mold, and placing them in a vacuum drying bin cooling on the shelf; the mold is a cube-shaped metal mold body (1) with semi-columnar grooves (2) on the upper surface, and small holes (3) are arranged on the mold body; 3) vacuuming; 4) Heating on the shelf, raising the temperature to 0°C, keeping the pressure at 20-100Pa, drying; raising the material from 0°C to 20°C, keeping the pressure at 10-20Pa, drying, raising the material from 20°C to 40°C, keeping the pressure within 10Pa , dried; raised to normal pressure; 5) low-temperature airflow pulverization to obtain more than 95% of the active dendrobium officinale superfine powder with a particle size of 20 μm or less. The invention has high freeze-drying rate, saves freeze-drying time, reduces energy consumption, has small particle size, is easy to dissolve and absorb, and has high bioavailability.

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 ...
