Problems solved by technology

The traditional processing method of clover decoction pieces usually adopts moistening, soaking, slicing, roasting and drying, and then puts them into textile bags after sulfur fumigation. During the moistening, soaking and roasting process, part of the active ingredients are lost and destroyed, resulting in obvious Reduced potency
Although this invention can improve the utilization rate of Clover, its processing is complicated and the processing cost is high
In addition, the invention does not provide technical enlightenment on how to effectively process the Clover Pieces
[0005] Although the invention of CN102846698A discloses a preparation method of trilobite green broken wall oral decoction pieces, through the preparation of trilobite green pretreatment, microwave vacuum freeze-drying, low-temperature pulverization, ultra-fine pulverization, granulation, etc., greatly in the production Improve the utilization rate of clover, but its raw material is dry clover (the folks believe that the effect of fresh clover is the best), and it is cut into 2-5cm decoction pieces during pretreatment, and microwave drying will inevitably produce Partially high temperature, in addition, spraying and granulation is used in the processing process, and the drying temperature at 50-70°C is relatively high, which destroys part of the active substances in Clover

Embodiment 1

[0029] (1) Pretreatment: Take fresh clover herb, remove impurities, wash with water, cut into 2-4mm thick slices;

[0030] (2) Freezing at low temperature: spread out the three leaf green slices obtained in step (1) and freeze them at -5°C.

[0031] (3) Low-temperature pulverization: pulverize the three leaf green tablets obtained in step (2) at a low temperature of -5°C, and sieve to obtain a coarse powder of 40-100 meshes.

[0032] (4) Low-temperature vacuum microwave drying: Put the clover powder obtained in step (3) into a vacuum microwave drying box for low-temperature vacuum microwave drying, control microwave power: 1kw, vacuum degree: 0.04Pa, temperature: -5°C ;The total time of microwave drying is 2h. During the microwave drying process, the microwave treatment method is adopted at intervals of 30s and heating for 30s (that is, heating for 30s, stopping heating for 30s, then continuing heating for 30s, stopping heating for 30s, and cycling in turn).

Abstract

The invention discloses a preparation method of radix tetrastigme powder. The preparation method comprises the following steps of 1, pretreatment: taking a fresh radix tetrastigme medical material, removing impurities, carrying out cleaning by water, and cutting the fresh radix tetrastigme medical material into slices or filing the fresh radix tetrastigme medical material into powder, 2, low-temperature refrigeration, 3, low-temperature crushing, 4, low-temperature vacuum microwave drying, 5, low-temperature air-flow crushing, 6, resonance grinding, and 7, split charging and packaging. The preparation method can realize complete breaking of cell walls of radix tetrastigme, complete release of various ingredients in radix tetrastigme cells, greatly improves penetration, realizes maximum absorption of effective ingredients and is conducive to medicinal action.

Description

technical field [0001] The invention belongs to the technical field of ultrafine pulverization of traditional Chinese medicines, and in particular relates to a preparation method of trefoil green powder. Background technique [0002] Under the guidance of traditional Chinese medicine and Chinese medicine theory, Chinese medicinal materials and their decoction pieces are undergoing tremendous changes. With the advancement of science and technology, advanced micro-powder machines and equipment continue to emerge. Bi Pieces emerged as the times require. It is a new type of Chinese herbal medicine developed on the basis of modern ultrafine pulverization technology. modern Chinese medicine decoction pieces.
