Problems solved by technology

The production method of natural copper is called slow fire, strong fire, dark red, etc. in terms of fire control. It lacks a clear concept of quantity, so it is difficult for different operators to master the forging conditions consistently, which will affect the accurate drug use.

Embodiment 1

[0056] A processing method for calcining natural copper with medicinal materials includes the following steps:

[0057] Steps of constant temperature forging: take natural copper and lay it in the forging pot, and use constant temperature for forging. The thickness of the tile is 50cm, and the forging is performed at a constant temperature of 650℃. The forging process is carried out in two stages for 6 hours. The process is flipped once;

[0058] The step of vinegar quenching: adding the calcined natural copper to the rice vinegar of 30% natural copper weight while it is hot, and stir-frying continuously; the concentration of the rice vinegar is 3.5%;

[0059] Drying steps: Place the fried natural copper in a drying oven and dry; the drying temperature is 55°C, and the drying time is 6h;

[0060] Steps for binning: use a 4-mesh sieve for binning; the calcined natural copper that passes through the 4-mesh sieve is the calcined natural copper of qualified grade;

[0061] Breaking steps: ...

Embodiment 2

[0064] A processing method for calcining natural copper with medicinal materials includes the following steps:

[0069] Breaking ste...

Embodiment 3

[0072] A processing method for calcining natural copper with medicinal materials includes the following steps:

[0073] Steps of constant temperature forging: take natural copper and flatten it in the forging pot, and use constant temperature for forging. The thickness of the flat is 60cm, and the forging is performed at a constant temperature of 700°C. The forging process is carried out in two stages for a total of 6 hours. The process is flipped once;

[0074] The step of vinegar quenching: adding the calcined natural copper to the rice vinegar of 30% natural copper weight while it is hot, and stir-frying continuously; the concentration of the rice vinegar is 3.5%;

[0075] Drying steps: Place the fried natural copper in a drying oven and dry; the drying temperature is 60°C, and the drying time is 10h;

[0076] Steps for binning: use a 4-mesh sieve for binning; the calcined natural copper that passes through the 4-mesh sieve is the calcined natural copper of qualified grade;

Abstract

The invention discloses a processing method and a product of calcined natural copper of a medicinal material, and the processing method comprises the following steps: a constant temperature calciningstep, a vinegar quenching step, an oven drying step, a grading step, a crushing step and a selection step, and then calcined natural copper is obtained. A technology for processing calcined natural copper, under the guidance of the pharmacopoeia, the production process of calcined natural copper was optimized, in the process of calcined and vinegar quenching at constant temperature, the best crispness and adsorption effect of rice vinegar were obtained. Ferrous sulfide in natural copper was changed from ferrous sulfide to ferrous sulfide, and acetate was used to form more soluble Fe(CH<3>COO)<3>, which ensured that the content of active ingredient was in conformity with the legal standard. Product appearance and internal quality improvement ensure the stability and reproducibility of varieties and processes.

Description

Technical field [0001] The invention relates to a traditional Chinese medicine processing technology, in particular to a processing method and product of natural copper forging medicine. Background technique [0002] Natural copper is a natural pyrite of tetragonal crystal system, and its main component is iron disulfide (FeS 2 ), has the functions of dispelling blood stasis and relieving pain, renewing tendons and bones. It is an important medicine for traditional Chinese medicine and traumatology. It usually needs to be processed before it can be used as medicine. [0003] The method for preparing calcined natural copper in the 2015 edition of the Chinese Pharmacopoeia is as follows: Take clean natural copper, calcinate it to dark red according to the calcining quenching method (General Rule 0213), and quench it with vinegar until the surface is dark brown, the gloss disappears and becomes loose. For every 100kg of natural copper, 30kg of vinegar is used. The natural copper prep...
