Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of the calcination process of kelpite on the market that there are no clear regulations on calcination temperature and calcination time, provide a unified calcination process of kelpite, and solve the problem of labor-intensive, time-consuming, and quality problems in production. The problem of unevenness is not conducive to mass production

Embodiment 1

[0017] Example 1 Method for calcining bluestone and fire nitrate

[0018] Crush the bluestone into small pieces of 2~5mm, wash and dry; take the raw bluestone with a weight ratio of 1:0.1~1:2.5 and mix well, and spread on 100ml with a thickness of 2~10cm Put the crucible into a muffle furnace and calcinate at a high temperature of 500~900℃ for 1~4h to obtain the sintered bluestone.

Embodiment 2

[0019] Example 2 Research on the calcination process of bluestone and fire nitrate

[0020] ⑴ Experimental method

[0021] Evaluation indicators for calcined products: the color, porosity, and water-soluble dissolution rate of calcined products are taken as indicators for evaluating the effect of calcining. The scoring rules are as follows:

[0022] (1) The color of the calcined product: 10 points for golden yellow, 6 points for dark yellow brown, 4 points for no yellow appearance;

[0023] (2) The porosity of the calcined product: the calcined product is loose (good fluidity, no agglomeration) as 10 points, relatively loose or crisp (some agglomerated, but loose with a little force) is rated as 6 points, and the hardness is evaluated. It is 4 points.

[0024] (3) Water-soluble dissolution rate: calculate the water-soluble dissolution rate of the sample based on the dried product.

[0025] Experimental design: adopt L 9 (3 4 ) Orthogonal table examines the layer thickness (A), the mass ...

Embodiment 3

[0036] Example 3 Verification of the calcination process of bluestone and fire nitrate

[0037] Three batches of samples were prepared according to the optimized conditions for the calcination of bluestone and fire nitrate in Example 2. The results showed that the color was golden yellow, the samples were loose, and the water-soluble dissolution rates were 29.48%, 29.47%, and 29.43%, indicating the optimal process The conditions are stable, reasonable and feasible.

Abstract

The invention discloses a calcining method of lapis chloriti potassium nitrate, which comprises the steps of: crushing lapis chloriti into small blocks with particle sizes of 2-5mm, cleaning and airing; taking raw lapis chloriti and potassium nitrate with a weight ratio of (1:0.1)-(1:2.5), spreading in a crucible at the thickness of 2-10cm, placing in a muffle furnace, and calcining at the temperature of 500-900 DEG C for 1h-4h to prepare the potassium nitrate calcined lapis chloriti. Meanwhile, color, looseness, water dissolution rate, contents of harmful elements, and the like are used as quality indexes of calcining the lapis chloriti. Experiments prove that the lapis chloriti product prepared by adopting the calcining method provided by the invention is remarkably increased in dissolution rate, and is reduced in contents of the harmful elements under the condition that the content of a main element water solution is not remarkably changed, thus the safety of clinical medication is increased. Therefore, an optimized method for preparing the lapis chloriti is established, the defect of non-uniformity in quality of the prepared lapis chloriti in the production is overcome, and a method and an idea are provided for unifying the lapis chloriti preparing standards in China.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and in particular relates to a method for calcining bluestone and fire nitrate. Background technique [0002] Chloriti Lapis (Chloriti Lapis) is a commonly used clinical mineral medicine with a long history of application. It has been included in historical pharmacopoeias. It is a metamorphic rock-like biotite schist or chloriteized mica carbonate schist. The clinical application of bluestone stone usually requires a process of processing. The ancient bluestone processing methods include firing, simmering, frying, simmering, and calcining vinegar. The modern processing methods include calcination, sintering, etc. Vinegar quenching and so on. The Chinese patent medicine preparations containing Qingzhushi included in the 2010 edition of "Chinese Pharmacopoeia" (Part One) include "Children Qingfei Pills", "Bei Ling Capsules", and "Zhuli Datan Pills". It is a calcined product, and i...
