Problems solved by technology

The conventional pulverization process needs to provide more energy. Therefore, the pulverization process is inefficient. Moreover, the mechanical energy is converted into heat energy, and the temperature of the medicinal material rises sharply, causing the loss of heat-sensitive components.

Embodiment 1

[0027] Saffron ultramicro decoction pieces are prepared according to the following preparation method:

[0028] (1) Take 1kg of saffron raw material, use camera imaging, computer graphics analysis, use picking location, stamen length, flower integrity, color and other factors as features to identify impurities and inferior medicinal materials, and use robotic hands to pick out local medicinal materials. Among them, the qualified medicinal materials are 0.94kg; the unqualified products are 0.06kg.

[0029] (2). Treat qualified saffron medicinal materials at low temperature and cool down according to the square function to -0.05℃ / min 2 Accelerate cooling to -15℃;

[0030] (3) Crush the pre-frozen medicinal materials into coarse powder at 5℃;

[0031] (4) The secondary treatment of saffron, first reduce the temperature to -40°C at a constant rate of -2°C / h, vacuum the system, keep the absolute pressure at 45Pa, and then sublime and dry. The sublimation temperature is 35°C and dry for 12 ...

Embodiment 2

[0037] Collect 60g of medicinal materials containing impurities automatically picked in Example 1, and place them in a manual picking platform. Use manual picking methods to pick out the high-quality saffron medicinal materials that were wrongly selected, gather them together, and return to the original qualified Chinese medicinal materials In order to improve the utilization rate of medicinal materials and reduce the loss of medicinal materials. 36 g of saffron medicinal materials were recovered after the second time, and the recovery rate was 60%.

Embodiment 3

[0039] The particle size analysis of saffron ultrafine decoction pieces powder uses laser particle size analysis.

[0040] Before the measurement, the laser particle size analyzer is turned on and preheated for more than 30 minutes.

[0041] Sampling: Add 2~4g of ultra-micro decoction pieces sample into the sampling tank, click start to start the analysis. In the measured data, the shading ratio should be controlled between 0.5 and 3, and the data whose shading ratio does not meet the requirements are eliminated, and the workstation automatically measures the particle size distribution and cumulative percentage of saffron ultrafine decoction pieces.

Abstract

The invention discloses a preparation method for a stigma croci ultramicro decoction piece. The preparation method comprises the following steps: choosing stigma croci through a local graphic processing technology, and removing impurities according to dislocation degree; performing low-temperature treatment on stigma croci medicinal material, and cooling to be not higher than (-)15 DEG C according to square function; smashing the pre-frozen medicinal material into crude powder, performing secondary treatment on the stigma croci, performing equal-speed cooling to freeze, performing microwave heating unfreezing, damaging the structure of the medicinal material through a method of heat expansion and cold contraction, thereby strengthening brittleness of the material and improving air-jet pulverizing efficiency; sampling and observing surface treatment results of the stigma croci material; and after the surface treatment results are qualified, crushing the material until the grain size is smaller than 5 microns through an air-jet pulverizing process, and performing bactericidal treatment, thereby obtaining the stigma croci ultramicro decoction piece. The preparation method for the stigma croci ultramicro decoction piece disclosed by the invention can effectively reduce loss of thermal sensitive components of the medicinal material in a processing process, and increases a dissolution rate of active ingredients, so that the blood circulating promoting function and the beautifying function of the stigma croci are improved.

Description

Technical field [0001] The present invention belongs to the technical field of processing precious fine Chinese medicinal materials. More specifically, the present invention relates to a process method for preparing ultra-micro decoction pieces using saffron medicinal materials as raw materials. Background technique [0002] Saffron (Saffron, Crocus sativus L.), also known as saffron, is a bulbous perennial herb of the genus Iridaceae, Crocus sativus. Its medicinal part is stigma. Its origin is in Greece, Spain, Iran and other countries, and it is imported from Tibet. My country. The "Compendium of Materia Medica" records "Saffron, going out of Xifan to return to the land and the kingdom of heaven, that is, red and blue flowers there. In Yuan Dynasty, it is used for food." Due to the low yield of saffron, harvesting is time-consuming and laborious. Its price remains high, and it is listed as a rare and precious Chinese medicinal material in my country, and it is even more known a...
