Embodiment 1

[0032] A preparation process of fresh Scrophulariaceae superfine powder, comprising the following steps:

[0033] (1) Material selection: take fresh Scrophulariaceae, wash with water, remove impurities, and drain;

[0034] (2) Beating: the fresh scrophulariaceae raw material is preliminarily crushed, and microcrystalline cellulose powder with a mass of 10 wt% of the raw material is added, and then the raw material is fully mixed with the microcrystalline cellulose by the rotation of the mixing tank; then the raw material mass is added 0.8 times of water beating;

[0035] (3) Pre-freezing: pre-freezing after beating, the standard of pre-freezing is to freeze into a solid state, and maintain the frozen solid state for 5 to 10 hours, and the pre-freezing temperature is -8 to -18°C; Before pre-freezing, add Tween 80 with a slurry mass of 10wt% and fully stir;

[0036] (4) Freeze-drying: freeze-drying after pre-freezing, the control condition of freeze-drying is -45~-50℃, the tim...

Abstract

The invention relates to a processing method for fresh radix scrophulariae, and particularly relates to a preparation technology for fresh radix scrophulariae superfine powder. The preparation technology comprises the following steps of (1) selecting materials; (2) pulping: after preliminarily smashing the raw material fresh radix scrophulariae, adding microcrystalline cellulose powder accounting for 10-20wt% of the raw material, then fully mixing the raw material and the microcrystalline cellulose through rotating a charging bucket of a mixing machine, and then adding water and pulping; (3) pre-freezing: adding tween 80 accounting for 10-15wt% of the pulp before pre-freezing and stirring completely; (4) freeze drying: controlling the water content below 6wt%; and (5) grinding into superfine powder through a vibrating type superfine grinding mixing mill. The fresh radix scrophulariae superfine powder prepared by the preparation technology can reserve active ingredients of the fresh radix scrophulariae to the maximum degree.

Description

technical field [0001] The invention relates to a processing method of fresh scrophulariae, in particular to a preparation process of fresh scrophulariae superfine powder. Background technique [0002] In the prior art, fresh Scrophulariaceae, a traditional Chinese medicine, is usually excavated when the stems and leaves wither in winter, and the rhizomes, seed buds, fibrous roots and silt are removed, sun-dried or baked until semi-dry, piled up for 3-6 days, and repeated several times. to dry. Modern research shows that the traditional processing method will lose a lot of active ingredients. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process of fresh scrophulariaceae superfine powder in order to solve the technical problem that the active ingredient retention of fresh scrophulariaceae superfine powder is not high enough in the prior art. The method can retain the active ingredients in the fresh scrophulariaceae to...
