Problems solved by technology

This invention avoids oxidation and decomposition of the active ingredients of medicinal materials caused by heating, drying and crushing under normal pressure, so that the product has basically the same taste, color and quality as fresh products. However, its pre-freezing and vacuum freeze-drying occupy a large amount of time. Time, in industrialized mass production, will reduce production efficiency, therefore, the present invention proposes improvement for this

Embodiment 1

[0023] A preparation method of active notoginseng fine powder, comprising the steps of:

[0024] S1. Pre-treatment: remove fibrous roots, velvet roots and notches from fresh Panax notoginseng roots to obtain main roots, clean the main roots of Panax notoginseng and grind them into mud to obtain material A;

[0025] S2. Activation treatment: Add wheat flour accounting for 1% of the mass of material A and yeast powder accounting for 0.5% of the mass of wheat flour to material A in step S1, stir evenly and let stand for 20 minutes to obtain material B;

[0026] S3. Initial vacuum freeze-drying: vacuum freeze-dry the material B in step S2 to obtain material C; the vacuum freeze-drying condition is to freeze the material B to -10°C and keep it under the condition of 5 Pa for 15 minutes;

[0027] S4. Constant temperature and humidity treatment: crush the material C in step S3 and place it under the conditions of temperature 35°C and humidity 65%RH for 10 minutes to obtain materi...

Embodiment 2

[0031] S1. Pre-treatment: remove fibrous roots, velvet roots and notches from fresh Panax notoginseng roots to obtain main roots, clean the main roots of Panax notoginseng and grind them into mud to obtain material A;

[0032] S2. Activation treatment: Add wheat flour accounting for 3% of the mass of material A and yeast powder accounting for 0.8% of the mass of wheat flour to the material A in step S1, stir evenly and let stand for 30 minutes to obtain material B;

[0033] S3. Initial vacuum freeze-drying: vacuum freeze-dry the material B in step S2 to obtain material C; the vacuum freeze-drying condition is to freeze the material B to -30°C and keep it at a pressure of 13Pa for 30 minutes;

[0034] S4. Constant temperature and humidity treatment: crush the material C in step S3 and place it under the conditions of temperature 45°C and humidity 75%RH for 15 minutes to obtain material D;

[0035] S5. Secondary vacuum freeze-drying: vacuum freeze-dry the material D in step...

Embodiment 3

[0038] This embodiment is similar to the embodiment 1, except that in the step S4, the constant temperature and humidity conditions are 50° C. and 85% RH. The average particle size of notoginseng fine powder is 8 microns.

Abstract

The invention relates to the technical field of deep processing of traditional Chinese medicines and in particular discloses a method for preparing active panax notoginseng fine powder. The method comprises the following steps: S1, performing pretreatment, namely cleaning fresh radix notoginseng taproot and preparing the cleaned fresh radix notoginseng taproot into slurry, thereby obtaining a material A; S2, performing activating treatment, namely adding wheatmeal and yeast powder into the material A obtained in the S1, uniformly stirring and standing, thereby obtaining a material B; S3, performing primary vacuum freeze drying, namely performing vacuum freeze drying on the material B in the S2, thereby obtaining a material C; S4, performing constant temperature and constant humidity treatment, namely crushing the material C in the S3, treating the material C under the conditions that the temperature is lower than 50 DEG C and the humidity is lower than 85%RH, thereby obtaining a material D; S5, performing secondary vacuum freeze drying, namely performing vacuum freeze drying on the material D in the S4 again, thereby obtaining a material E; and S6, performing superfine grinding, namely performing superfine grinding treatment on the material E in the S5, thereby obtaining the active panax notoginseng fine powder. According to the method, the time of preparing the panax notoginseng fine powder is greatly shortened, and the taste of the panax notoginseng fine powder and the stability of the active ingredients are improved.

Description
