Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of ocher calcination process currently on the market that there are no clear regulations on calcination temperature, vinegar concentration, calcination time and programmed temperature rise time, to provide a unified ochre calcination process, and to solve the problem of labor-intensive, time-consuming and labor-intensive production. The problem of uneven quality is not conducive to mass production

Embodiment Construction

[0064] An optimum calcining process for ochre, characterized in that the process steps are as follows

[0065] (1) Break ocher into small pieces of 4-5 mm, wash, dry, and place the ochre in a crucible with a thickness of 2 cm;

[0066] (2) According to ocher calcining temperature (650°C, 750°C, 850°C), vinegar concentration (3.8g / 100mL, 5.0g / 100mL, 6.4g / 100mL), calcining time (1h, 1.5h, 2h), Program heating time (20min, 40min, 60min) four investigation factors, each factor takes 3 levels, choose L 9 (3 4 ) Orthogonal table arrangement test, according to the orthogonal test scheme, the ocher obtained in the previous step is calcined, and each test number is repeated 3 times (shown in Tables 2, 3, and 4);

[0067] (3) Determination of the relative hardness, porosity, and Fe in the decoction of calcined ochre obtained in the previous step 2+ The method of As content in content, water decoction is as follows:

[0068] ① Determination of relative hardness of calcined ochre by M...

Abstract

The invention discloses an ocher calcining process comprising the following steps: (1), breaking, washing and drying the ocher in air in a crucible; (2),selecting three levels of each of the four considering factors of calcining temperature, vinegar concentration, calcining time and program warming up time, and calcining the ocher using L9(34) orthogonal table; (3), measuring hardness, sedimentation and Fe2+ and As conternt in decocting water to the calined ocher; (4), calculating the integrative score of the measurement result in step (3); (5), performing variance analysis to the integrative score to obtain the optimal ocher calcining processing condition is that: the calcining is 850 degrees centigrade, the calcining time is 2h, the temperature programming time is 20 min, and the used vinegar total acid content is 5.0g / 100mL. The invention provides an optimal ocher calcining processing condition, further proposes to use relative hardness, sedimentation and Fe2+ and As conternt in decocting water as quality criterion of the calcined ocher, and establishes an objective evaluation criterion.

Description

technical field [0001] The invention relates to a process for calcining ocher, which belongs to the technical field of traditional Chinese medicine. Background technique [0002] The ocher oxide mineral corundum hematite (Haematitum), the main component is ferric oxide (Fe 2 o 3 ), cold in nature, bitter in taste, has the effects of calming the liver and suppressing yang, lowering the adverse, and stopping bleeding. [0003] The processing method of ocher has a long history. In ancient times, there were many processing methods such as crushing, grinding, water flying, simmering, burning, calcining and quenching. The 2005 edition of "Chinese Pharmacopoeia" stipulates that the ochre should be calcined to red through the calcining method, quenched with vinegar, and ground into a coarse powder. The calcining and quenching method is as follows: when the pure ochre is calcined until it is completely red, it is immediately put into vinegar, quenched, taken out, dried, crushed or...
