[0132] A preparation method of Miao medicine incense beads includes the following steps:

[0133] Step One: Pretreating traditional Chinese medicine materials:

[0134] a. Cleaning: Rinse the recycled and used traditional Chinese medicine materials with clean water to remove sand and impurities.

[0135] b. Draining: Drain the water from the cleaned traditional Chinese medicine materials, and then dehydrate them with a centrifuge to avoid mildew caused by excessive moisture during the subsequent drying process.

[0136] Step Two: Drying traditional Chinese medicine materials: Adopt a low-temperature segmented drying process. During the drying process, maintain the low humidity of the hot air through dehumidification technology to improve the drying efficiency. The specific operation is as follows:

[0137] The first stage: Use hot air at a temperature of 50 °C to pre-dry the materials for 24 minutes, so that the moisture content of the materials is reduced to a certain level.

[0138] The second stage: Further dry under the combined action of microwave at 2500 MHz and hot air at 50 °C for 12 minutes.

[0139] The third stage: Use hot air at 48 °C to dry again for 14 minutes until the materials meet the final moisture content requirement ≤ 5%.

[0140] Step 3. Crushing Chinese medicinal materials: The ultrafine crushing process is adopted, and the specific operation is as follows:

[0141] (1) Preparation work: Prepare the Chinese medicinal materials to be crushed; check whether the equipment is normal, whether each component is fastened, and whether the power cord and power plug are normal; put the Chinese medicinal materials into the hopper, turn on the power switch, and after confirming that the voltage is stable and correct, turn on the power switch;

[0142] (2) Start crushing: According to the types and crushing requirements of the Chinese medicinal materials, adjust parameters such as rotation speed, temperature, and crushing time, press the start button to start working. During the crushing process, observe the working state of the crusher and adjust the parameters to obtain a better crushing effect;

[0143] (3) Crushing completion: When the crushing time reaches the preset time of 30 minutes or reaches the ideal crushing degree and the crushing particle size reaches 1800 mesh, stop working and turn off the power switch. Take out the crushed ultrafine powder of Chinese medicine and carry out packaging and storage;

[0144] (4) Cleaning and disinfection: After use, it needs to be cleaned and disinfected. First, clean the residues in the crusher, and then disinfect each component of the crusher with a disinfectant to ensure hygienic safety during the next use;

Ultrasonic power: within the range of 200 - 1000 W, a suitable power can be selected according to the sample amount and equipment capacity. Ultrasonic frequency: between 20 - 40 kHz. Different frequencies have an impact on the extraction effect and need to be adjusted according to specific circumstances;

[0149] D. Monitoring the extraction process: During the ultrasonic treatment process, take samples regularly for analysis to monitor the extraction of the target components. Extraction time: 40 minutes; Extraction temperature: usually between room temperature and 80 °C to prevent the loss of heat-sensitive components due to temperature. Conduct multiple extractions to improve the extraction rate;

[0150] E. Extract separation: After the ultrasonic treatment, first use filter paper or filter cloth to roughly filter the extract to remove medicinal residues and large particle impurities; then further use a 0.37 μm microporous membrane for fine filtration to remove fine particles; finally, centrifuge. Put the extract into a centrifuge and centrifuge at 4000 rpm for 13 min to separate solid impurities and supernatant;

[0151] F. Post-treatment of the extract: Adopt the method of reduced pressure concentration to avoid destroying the thermosensitive components in traditional Chinese medicine at high temperature. Pour the extract into the evaporation flask of a rotary evaporator; set the water bath temperature to 50 °C, turn on the vacuum pump to reduce the system pressure, so that the solvent evaporates at a lower temperature, and collect the concentrated solution until the required volume or concentration is reached;

[0152] Step Five: Making incense beads:

[0153] 1) Powder mixing: Use a 1500-mesh sieve to sieve medicinal powder and Phoebe zhennan powder in a ratio of 7:3, and mix them evenly;

[0154] 2) Adding and mixing the extract: Add the extracted Miao medicine extract to the mixture. The ratio of the mixture to the extract is 1:1. Stir while adding, and knead the mixture into a uniform dough-like shape, ensuring that there is no dry powder or excessive moisture, and it is appropriate to be able to knead into a ball without sticking to the hands;

[0155] 3) Shaping: Seal the dough-like mixture with plastic wrap and ferment for 1 hour. Take an appropriate amount of the mixture and roll it into small balls with a diameter of about 1.2 cm, ensuring that the surface of the incense beads is smooth and without cracks; Fill the mixture into a mold, press it firmly and then demold to obtain incense beads with regular shapes. If there are cracks on the surface of the incense beads, moisten your fingers with a little water and gently smooth them;

[0156] 4) Natural drying: Place the shaped incense beads on a drying rack and let them dry naturally in a ventilated and cool place. The drying time is 4 days, depending on the specific environment;

[0157] 5) Sanding, polishing and waxing: The surface of the dried incense beads may be slightly rough. Gently sand it with 900-mesh fine sandpaper to make the surface smooth. Wipe the incense beads with a polishing board to make the surface shiny. Finally, apply wood wax oil to prevent insects and moisture;

[0158] Step Six: Processing the finished product: Package the made incense beads into bracelets, necklaces, hairpins, hair clips, etc. to improve the aesthetics and commercial value;

[0159] Step Seven: Storage: Put the incense products into a sealed bag or sealed jar and store them in a cool and dry place.

[0160] The test of the influence of the ultra-fine grinding particle size on the quality of incense beads in the present invention is as follows:

[0161] Test method: The dried Chinese medicinal materials were respectively pulverized to 1250 mesh, 1800 mesh, and 2000 mesh, and 50 g of powder was taken from each. Through the adsorption test, the powder was placed in a closed container containing volatile organic gases (VOCs) at a certain concentration. After a period of time, the gas concentration in the container was detected, and the adsorption rate of the powder to VOCs was calculated; for the forming stability test, the powder was made into incense bead blanks, and the deformation and cracking conditions during natural drying were observed, and the forming success rate was recorded.

[0162] Test results: The adsorption rate of the 1250-mesh powder to VOCs was 75%, and the forming success rate was 80%; the adsorption rate of the 1800-mesh powder reached 85%, and the forming success rate was 90%; the adsorption rate of the 2000-mesh powder was 90%, and the forming success rate was 92%. Considering comprehensively, the 1800-mesh powder showed a relatively balanced performance in terms of adsorption and forming stability. It could not only effectively adsorb odors but also ensure a high forming quality. The particle size was detected to be ≤100 μm, meeting the expected requirements, as shown in Table 3 below.

[0163] Table 3 Influence of ultra-fine grinding particle size on the quality of incense beads

[0164] Particle size (mesh) Hardness of the incense beads Uniformity of the incense beads Duration of fragrance retention (hours) 1000 3.8 85% 48 1500 4.2 92% 60 2000 4.5 95% 72

[0165] Note: The hardness of the incense beads was measured by a Shore hardness tester, the uniformity was evaluated by visual inspection, and the aroma persistence was evaluated by sensory testing.

[0166] The test on the influence of ultrasonic-assisted extraction on the extraction efficiency in the present invention is as follows:

[0167] Taking the formula of the exorcising and calming the nerves incense beads as an example, different ultrasonic powers (200 W, 600 W, 1000 W), frequencies (20 kHz, 30 kHz, 40 kHz), and extraction times (10 min, 40 min, 60 min) were set respectively, and each group of tests was repeated 3 times. High-performance liquid chromatography (HPLC) was used to determine the contents of the target efficacy components such as calming the nerves and repelling mosquitoes in the extract, and the extraction efficiency was calculated.

[0168] Test results: When the ultrasonic power was 600 W, the frequency was 30 kHz, and the extraction time was 40 min, the extraction efficiency was the best. Compared with the traditional extraction method, the extraction efficiency of the target components was increased by 30%. Under these conditions, the contents of the main efficacy components in the extract reached a relatively high level. The content of cineole in the volatile oil of Artemisia argyi was 5 mg / g, and the content of camphor was 3 mg / g; the content of cedrol in Platycladus orientalis seeds was 4 mg / g, which could effectively ensure the efficacy of the incense beads, as shown in Table 4 below.
