Abstract
Description
Technical Field
[0001] This invention relates to the field of traditional craftsmanship, and in particular to a traditional preparation process for Gastrodia elata incense sticks. Background Technology
[0002] Incense sticks, also known as longevity incense or fairy incense, are usually made from natural plant fragrances such as sandalwood and agarwood. They are shaped like thin, long threads, hence the name incense sticks. When lit, incense sticks produce a fragrance that can purify the air and has a calming effect. They are often used for indoor aromatherapy, religious ceremonies, and other occasions. Incense sticks not only have practical value but also contain rich cultural connotations. Some of the incense stick making techniques are my country's intangible cultural heritage.
[0003] Experience-dependent factors lead to quality fluctuations: Traditional incense making relies on the personal experience of artisans, and key parameters such as raw material ratios and processing time lack quantitative standards, which restricts large-scale production and market access.
[0004] Traditional production processes have shortcomings: the extraction process is outdated, and natural fragrances (such as agarwood) are still mainly extracted by traditional distillation, resulting in a low extraction rate (more than 30% lower than microwave-assisted extraction) and serious loss of active ingredients.
[0005] While hydraulic incense making improves efficiency, the high pressure causes the incense to become dense, hindering the release of volatile oils and resulting in a "smoking first, burning later" failure—the aroma is not fully released and the ash turns black and curls. To compensate, talc (flame retardant) and combustion aids need to be added, leading to a vicious cycle. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a traditional preparation process for Gastrodia elata incense sticks.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A traditional preparation process for Gastrodia elata incense sticks includes the following steps:
[0009] S1, AI-driven fragrance development: By digitizing dimensions such as aroma concentration and chemical properties and combining them with convolutional neural network algorithms, the efficiency of fragrance development is increased by 10 times, the customized response time is shortened by 36%, and the fragrance formula can be automatically optimized, reducing the development cycle by 60%.
[0010] S2. Low-temperature cell wall breaking extraction of Gastrodia elata: Supercritical CO2 extraction (parameters: 35℃, 15MPa) is used to extract gastrodin, avoiding high temperature damage. The extract is encapsulated with β-cyclodextrin to form heat-resistant microcapsules, which improves the combustion resistance to 300℃.
[0011] S3. Stepwise fusion: Extract frankincense resin with anhydrous ethanol, mix gastrodia microcapsules, frankincense resin and borneol together, and knead by hand to form a core material with a diameter of 0.5mm.
[0012] Clematis chinensis and Clematis armandii were ultra-finely pulverized using a 200-mesh ultra-fine pulverizer. Then, Clematis chinensis, Artemisia argyi powder, and natural binders were mixed together and coated onto the core material. The mixture was then air-dried at a humidity of 40% and a temperature of 25℃.
[0013] S4. Combustion control: Add a combustion regulator to the air-dried core material. The combustion regulator is made by mixing potassium nitrate and bamboo charcoal powder in a ratio of 1:9 to form the shell.
[0014] S5. Molding and quality inspection: The core material and outer shell are squeezed into thin strips by hand rolling or using molds. After shaping, the prepared incense sticks are cut into multiple sections, each 21cm long, and sampled for testing.
[0015] Preferably, the ratio of the extract to β-cyclodextrin is 1:8, and the natural binder is a mixture of elm bark and nanmu powder in a ratio of 3:7.
[0016] Preferably, the core material needs to be left to stand for 2 hours after kneading to promote the fusion of frankincense resin and microcapsules. During the standing process, the core material is placed in a ceramic jar at 25°C.
[0017] Preferably, the combustion modifier powder for the shell layer is added in three stages: the first layer is a thin coating, then it is air-dried for one hour, then a second layer of powder is added and the mixture is plasticized, and finally a third layer of powder is added, and the mixture is compacted to eliminate air bubbles.
[0018] Preferably, during the air-drying process, direct sunlight should be avoided to prevent ultraviolet radiation from degrading the active ingredients in the incense sticks; ventilation should be prevented to avoid cracking of the incense stick surface; and moisture should be prevented by turning the incense sticks three times a day to prevent them from becoming damp and unable to be lit.
[0019] Preferably, when treating damp-heat arthralgia, mugwort leaves are replaced with carbonized granules of phellodendron bark.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. Through intelligent AI and algorithms, existing incense sticks are digitally analyzed to achieve automatic optimization of fragrance formulas, which increases fragrance blending efficiency by 10 times, shortens customization response time by 36%, and reduces the R&D cycle by 60%. At the same time, the digital formula is more accurate, and the raw material ratio and processing time can be quantified, avoiding fluctuations in the quality of incense sticks and facilitating large-scale production and market access.
[0022] 2. By reforming traditional processes through advanced technologies, the extraction rate of raw materials is greatly improved through advanced equipment such as supercritical CO2 extraction and ultra-high-power pulverization devices, which not only saves preparation time but also reduces material waste.
[0023] 3. Kneading and pressing are still done manually, with molds used to knead the core material into shape. This avoids the situation where high pressure causes the fragrance to become dense, which hinders the release of volatile oils and leads to the failure of "smoking first and then burning".

[0024] Figure 1 This is a schematic diagram of the traditional preparation process of Gastrodia elata incense proposed in this invention. Detailed Implementation
[0025] Reference Figure 1 A traditional preparation process for Gastrodia elata incense includes the following steps:
[0026] S1, AI-driven fragrance development: By digitizing dimensions such as aroma concentration and chemical properties and combining them with convolutional neural network algorithms, the efficiency of fragrance development is increased by 10 times, the customized response time is shortened by 36%, and the fragrance formula can be automatically optimized, reducing the development cycle by 60%.
[0027] S2. Low-temperature cell wall breaking extraction of Gastrodia elata: Supercritical CO2 extraction (parameters: 35℃, 15MPa) is used to extract gastrodin, avoiding high temperature damage. The extract is encapsulated with β-cyclodextrin to form heat-resistant microcapsules, which improves the combustion resistance to 300℃. The core material releases the drug slowly when heated, and the encapsulation layer blocks high temperature, increasing the retention rate of active ingredients to 85%.
[0028] S3. Stepwise fusion: Extract frankincense resin with anhydrous ethanol, mix gastrodia microcapsules, frankincense resin and borneol together, and knead by hand to form a core material with a diameter of 0.5mm.
[0029] Clematis chinensis and Clematis armandii are ultra-finely pulverized using a 200-mesh ultra-fine pulverizer. Then, Clematis chinensis, Artemisia argyi powder, and natural binders are mixed together. This mixture is then coated onto the core material and air-dried at 40% humidity and 25℃. The material is hand-kneaded to ensure porosity, resulting in a density of 0.65 g / cm³. 3 To avoid the "fumigation before burning" method becoming ineffective;
[0030] S4. Combustion control: Add a combustion regulator to the air-dried core material. The combustion regulator is made by mixing potassium nitrate and bamboo charcoal powder in a ratio of 1:9 to form the shell.
[0031] S5. Molding quality inspection: The core material and outer shell are squeezed into thin strips by hand rolling or using molds. After shaping, the prepared incense sticks are cut into multiple sections, each 21cm long, and sampled for testing.
[0032] β-cyclodextrin microcapsules resist degradation at 300℃, frankincense resin activates skin TRPV1 channels, opens the transdermal barrier, and the core-shell sustained-release structure prolongs drug action to 4 hours;
[0033] Gastrodia elata has the effects of calming wind and promoting blood circulation, anti-inflammatory and analgesic. It is extracted and processed by supercritical CO2. The extract is encapsulated with β-cyclodextrin (or ground into fine powder) at a dosage of 300g / 1000g as the main body of the core material, which can prevent pyrolysis and inactivation at 300℃.
[0034] Clematis chinensis has the effects of dispelling wind and dampness and softening bone spurs. It is made by pulverizing it into 200-mesh ultrafine powder, using a dosage of 200g / 1000g, and mixing it with a binder to form a shell layer.
[0035] Frankincense promotes blood circulation and facilitates skin penetration, guiding the medicine into the meridians. It is used as a binder for the core material by extracting resin with anhydrous ethanol at a dosage of 150g / 1000g, which increases the permeability of gastrodin by 5 times.
[0036] Artemisia argyi charcoal has the effect of warming the meridians and dispelling cold (suitable for cold-dampness arthralgia). Artemisia argyi is first calcined and carbonized, and then nano-ground. The dosage is 150g / 1000g. It has the effect of reducing irritation and enhancing the ability to adsorb toxic molecules.
[0037] Borneol has the effects of opening the mind and refreshing the spirit, and promoting transdermal absorption. It uses natural borneol crystals, with a dosage of 150g / 1000g, as a core material volatile carrier.
[0038] Agarwood has the effects of regulating qi and relieving pain, and stabilizing the burning of incense. After aging for 3 years, it is ground into powder with a mesh size of 30 and the dosage is 100g / 1000g. This helps to harmonize the medicinal properties and improve the problem of burning off the end of the incense.
[0039] The nanmu wood adhesive powder acts as a natural binder and provides low-smoke combustion aid. It is refined using a water-milling method, with a dosage of 250g / 1000g. The shell matrix has a density of 0.65g / cm³. 3 ;
[0040] After kneading, the core material needs to be left to stand for 2 hours to promote the fusion of frankincense resin and microcapsules. During the standing process, the core material is placed in a ceramic jar at 25°C.
[0041] The combustion modifier powder for the shell layer is added in three stages. The first layer is a thin coating, then it is air-dried for one hour. The second layer is then applied and the powder is shaped. Finally, the third layer is applied, and the powder is compacted to eliminate air bubbles.
[0042] During the air-drying process, direct sunlight should be avoided to prevent ultraviolet radiation from degrading the active ingredients in the incense sticks; ventilation should be prevented to avoid cracking of the surface of the incense sticks; and moisture should be prevented by turning the incense sticks three times a day to prevent them from becoming damp and unable to be lit.
[0043] When treating damp-heat arthralgia, mugwort leaves can be replaced with carbonized phellodendron bark granules. Carbonized phellodendron bark granules have the effect of clearing heat and drying dampness, and are used to treat damp-heat arthralgia.
[0044] In this invention, the aroma concentration and chemical properties are first digitized, and combined with a convolutional neural network algorithm, the fragrance blending efficiency is increased tenfold, the customized response time is shortened by 36%, and automatic optimization of fragrance formulations is achieved, reducing the R&D cycle by 60%. Then, supercritical CO2 extraction (parameters: 35℃, 15MPa) is used to extract gastrodin, avoiding high-temperature damage. The extract is encapsulated with β-cyclodextrin to form heat-resistant microcapsules, improving combustion resistance to 300℃. Frankincense resin is extracted with anhydrous ethanol. The gastrodin microcapsules, frankincense resin, and borneol are mixed together and hand-kneaded to form a core material with a diameter of 0.5mm. Clematis chinensis and Clematis armandii are then ultra-finely pulverized using a 200-mesh ultra-fine pulverizer. Clematis armandii, Artemisia argyi powder, and a natural binder are then mixed together and coated onto the core material. The mixture is then air-dried at 40% humidity and 25℃, with hand-kneading to ensure porosity. The fragrance density is 0.65g / cm³. 3 To avoid the failure of "fumigation before burning", a combustion modifier is added to the air-dried core material. The combustion modifier is made by mixing potassium nitrate and bamboo charcoal powder in a ratio of 1:9. The shell is then formed, and the core-shell sustained-release structure prolongs the drug's effect to 4 hours.
