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 method for processing medicinal material calcined natural copper, comprising the steps of:

[0057] Steps of constant temperature forging: take natural copper and spread it in the calciner, and use constant temperature for forging. The process flips once;

[0058] The step of vinegar quenching: add the calcined natural copper into rice vinegar with 30% natural copper weight while it is hot, and stir fry continuously; the concentration of the rice vinegar is 3.5%;

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

[0060] Classification steps: use 4-mesh sieve to classify; calcined natural copper passing through 4-mesh sieve is calcined natural copper of qualified grade;

[0061] The step of crushing: breaking the large-scale calcined natural copper that cannot pass through the 4-mesh sieve into granular shapes;

[0062] Selection steps: select the crushed and qualifi...

Embodiment 2

[0064] A method for processing medicinal material calcined natural copper, comprising the steps of:

[0067] Drying steps: place the stir-fried natural copper in a drying oven, and dry; the drying temperature is 58°C, and the drying time is 8 hours;

[0068] Classification steps: use 4-mesh sieve to classify; calcined natural copper passing through 4-mesh sieve is calcined natural copper of qualified grade;

[0069] The step of crushing: breaking the large-scale calcined natural copper that cannot pass through the 4-mesh sieve into granular shapes;

[0070] Selection steps: select the crushed and qualifi...

Embodiment 3

[0072] A method for processing medicinal material calcined natural copper, comprising the steps of:

[0073] Steps of constant temperature forging: take natural copper and spread it in the calciner, and use constant temperature for forging. The process flips once;

[0074] The step of vinegar quenching: add the calcined natural copper into rice vinegar with 30% natural copper weight while it is hot, and stir fry continuously; the concentration of the rice vinegar is 3.5%;

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

[0076] Classification steps: use 4-mesh sieve to classify; calcined natural copper passing through 4-mesh sieve is calcined natural copper of qualified grade;

[0077] The step of crushing: breaking the large-scale calcined natural copper that cannot pass through the 4-mesh sieve into granular shapes;

Abstract

The invention discloses a processing method and a product for calcining natural copper with medicinal materials. The processing method comprises the following steps: a step of constant temperature calcination, a step of vinegar quenching, a step of drying, a step of grading, a step of breaking, and the steps of selecting Step, namely get calcined natural copper. The processing technology of calcined natural copper, on the one hand, under the guidance of the preparation method of the "Pharmacopoeia", the production process of calcined natural copper is optimized, and the processing process of calcination and vinegar quenching in a constant temperature method is adopted to obtain the best crispy effect and rice vinegar adsorption effect. The iron sulfide in natural copper is changed from ferrous iron to high iron, and exists in the form of acetate to generate more soluble acetate Fe(CH 3 COO) 3 , to ensure that the content of active ingredients meets the legal standards; the product appearance and internal quality are improved to ensure the stability and reproducibility of the variety process.

Description

technical field [0001] The invention relates to a processing technology of traditional Chinese medicine, in particular to a processing method and product of medicinal calcined natural copper. Background technique [0002] Natural copper is natural pyrite in the tetragonal system, and its main component is iron disulfide (FeS 2 ), has the functions of dispelling blood stasis and relieving pain, reconnecting tendons and bones, and is an important medicine for traumatology in traditional Chinese medicine. It generally needs to be processed before it can be used as medicine. [0003] The 2015 edition of "Chinese Pharmacopoeia" records the production method of calcined natural copper as follows: take clean natural copper, calcine it to dark red according to the method of calcining and quenching (general rule 0213), and quench it with vinegar until the surface is dark brown, the luster disappears and becomes loose. For every 100kg of natural copper, use 30kg of vinegar. The meth...
