Problems solved by technology

[0006] At present, the development of many Dendrobium candidum products is only at the low level of primary processing, and the deep-processed products are insufficient or the development of new products is not enough. In addition, due to the high commercial value of Dendrobium candidum, the promotion of it in the market is too exaggerated, resulting in shoddy products Phenomena emerge in endlessly

Embodiment 1

[0031] The preparation technology of dendrobium officinale freeze-dried powder comprises the following steps:

[0032] (1) Raw material preparation: get Dendrobium officinale meeting the requirements of the "Pharmacopoeia of the People's Republic of China" (2015 edition), wash with water, remove sundries, and rinse with purified water;

[0033] (2) Cut into pieces: mechanically cut into sections, cut into 2-4cm;

[0034] (3) Crushing and beating: add pure water according to the ratio of solid-liquid ratio 1g: 100ml for crushing and beating, grinding speed: 3000rpm, operating temperature: 40°C, pass through a 30-mesh filter, and receive the pulp;

[0035] (4) Vacuum drying: Take the above juice, pre-freeze overnight at -18°C to -20°C, then vacuum freeze-dry, set the cold trap temperature to -26°C, vacuum degree -0.9 to -0.1 Pa, freeze-drying time 18h, The final sublimation time is 14 hours, and the sublimation temperature is 40-45°C;

[0036] (5) Pulverization: the freeze-dri...

Embodiment 2

[0038] The preparation process of the freeze-dried powder of Dendrobium officinale is the same as in Example 1, except that in step (4), the freeze-drying time is 20 hours, and the sublimation is 16 hours.

Embodiment 3

[0040] The preparation technology of dendrobium officinale freeze-dried powder comprises the following steps:

[0041] (1) Raw material preparation: get Dendrobium officinale meeting the requirements of the "Pharmacopoeia of the People's Republic of China" (2015 edition), wash with water, remove sundries, and rinse with purified water;

[0042] (2) Cut into pieces: mechanically cut into sections, cut into 2-4cm;

[0043] (3) Crushing and beating: add pure water according to the ratio of solid-liquid ratio 1g: 80ml for crushing and beating, grinding speed: 3500rpm, operating temperature: 42°C, pass through a 28-mesh filter, and receive the pulp;

Abstract

The invention discloses a preparation process of dendrobium candidum freeze-dried powder, which comprises the following steps: (1) raw material preparation: take the dendrobium candidum that meets the standard, wash with water, remove impurities, and rinse with purified water; (2) cut into pieces: mechanically Cut into sections, cut into 2-4cm; (3) crushing and beating: add pure water according to the ratio of solid-liquid ratio 1g: (80‑120) ml for crushing and beating, and pass through a 28‑32 mesh filter to receive the pulp; (4 ) Vacuum drying: Take the above juice, pre-freeze overnight at -18°C ~ -20°C, then vacuum freeze-dry, freeze-dry for 16-22h, and finally sublimate for 12-18h; The freeze-dried powder is crushed neatly, and the particles are passed through a 70‑90 mesh sieve. Compared with the prior art, the method of the present invention is simple to operate, and the steps are scientific and reasonable, and there is no solvent pollution or residue in the preparation process of the freeze-dried powder of Dendrobium candidum; the preparation temperature is low, ensuring that the biological activity of the functional substances in Dendrobium candidum is not affected loss.

Description

technical field [0001] The invention relates to a preparation process of dendrobium officinale freeze-dried powder, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Dendrobium candidum products currently on the market, one is to make stems into dry products, that is, Tiepi Fengdou, which cuts off the leaves and fibrous roots of Dendrobium candidum, and twists them into spiral or spring-shaped dry products while drying; the other is fresh products Direct sales, including stems, flowers and leaves; the third is intensive processing products, mainly including granules, capsules, extracts, oral liquids, buccal tablets, tea, compound preparations and other types of medicines and health food. Various types of health food have been developed, and most of them are compound health products with other ingredients added. Dendrobium candidum health food is generally composed of two or more medicinal materials (including Dendrobium candidum)...
