Description

Technical Field

[0001] The invention belongs to the technical field of heating treatment, and particularly relates to a preparation method and an application method of a standard medicinal piece model for fire intensity testing. Background Art

[0002] The "huo" in the term "huohou" (fire) refers to heating, while "hou" (hou) represents time. There's a saying that "five days constitute one hou." According to traditional concepts, huohou refers to "the intensity of the fire and the duration of the heating," essentially the degree to which a substance is heated. While firepower and huohou are both distinct and related, firepower refers to the intensity, strength, or temperature of the fire, while huohou is a combination of both firepower and time.

[0003] The heat and duration required for traditional Chinese medicine preparation, such as boiling, stir-frying, calcining, and steaming, vary, resulting in reduced toxicity, increased efficacy, and altered medicinal properties. Heat is the cumulative effect of the time it takes to achieve a certain temperature, encompassing the intensity of the heat, the duration of the heating, and the overall internal and external changes to the medicine during the heating process. Understanding and judging "heat" largely relies solely on the operator's sensory inspection and experience, influenced by various human factors and subject to arbitrariness. This falls significantly short of modern precision requirements, and quantitative research on correlation evaluation indicators for "heat" is a common problem that urgently needs to be addressed. In particular, when heating the same object under different heating environments and conditions, it's difficult to find correlation to achieve the same heating effect.

[0004] In the prior art, there are evaluation methods for defining the intensity and degree of heat for medicinal preparations. However, when studying the heating effects of medicinal materials, this evaluation method usually uses the medicinal preparations themselves in medical institutions or laboratories to conduct standardized heat and temperature processing experiments using water or other heat-conducting media as a reference. However, in a heating system with calibrated heat intensity, the optimal heat intensity for processing is verified by processing medicinal preparations. By measuring the appearance and internal component content of the processed medicinal preparations, the quality of the frying process is comprehensively evaluated. This can lead to inaccurate verification test results due to a variety of factors. The specific reasons are as follows: Differences in medicinal materials: The quality of Chinese herbal medicines is affected by many factors, such as the type of medicinal materials, origin, harvesting time, processing methods, individual differences, etc. These factors may cause the medicinal materials to show different degrees of changes during the frying process, thereby affecting the judgment of the results.

[0005] Uneven heating: Due to differences in the shape and size of medicinal materials, even if the frying container and frying method are exactly the same, the medicinal materials will still be heated unevenly during the frying process, resulting in different results after the same pot of medicinal materials comes out of the pot, which also increases the difficulty of firepower measurement. Summary of the Invention

[0006] To solve the problems existing in the prior art, the present invention provides a method for preparing a standard decoction piece model for fire intensity testing and an application method, which can improve the accuracy and practicability of fire intensity testing by artificially manufacturing idealized traditional Chinese medicine decoction pieces.

[0007] The technical solution adopted by the present invention is as follows: In the first aspect, the present invention provides a method for preparing a standard decoction piece model for fire intensity testing, and making particulate matter with standard specifications for frying to determine the fire intensity. First, select starch-based traditional Chinese medicine decoction pieces, fried leaching traditional Chinese medicine decoction pieces or effective ingredient decomposition traditional Chinese medicine decoction pieces as the reference for gelatinization as the reference substances. After cleaning, classifying and sorting, they are used as the standby decoction piece materials. Then, select one or more of the standby decoction piece materials for mixing, drying and pulverizing, and obtain powders or coarse granular pulverized materials with a particle size of 1μm - 1000μm. Add the pulverized material to water and mix it evenly to form a mass of material. Form pills, tablets, or blocks with a unified shape from the mass of material through equipment or manual processing, and dry them to form a standard decoction piece model.

[0008] It should be noted that as a standard decoction piece model, it is actually a dispersed material with several standard shapes and homogeneous materials. Its main components are divided into three categories. The degree of gelatinization mainly forms a contrast through the color differentiation, and then the other two are set according to the requirements of the decoction piece type. The so-called fried leaching type means that its components can leach out the corresponding components when the fire intensity reaches the standard, that is, to detect the chemical component dissolution characteristics of this type of medicinal material after being heated. And the effective ingredient decomposition type refers to the change in the content of the effective ingredients originally contained in it, so as to judge whether the fire intensity has affected the effective ingredients of the medicinal material itself and caused their decomposition. Mainly refer to the above three judgment directions.

[0009] Combined with the first aspect, the present invention provides the first implementation manner of the first aspect, and the reference substances simultaneously include starch-based traditional Chinese medicine decoction pieces, fried leaching traditional Chinese medicine decoction pieces and effective ingredient decomposition traditional Chinese medicine decoction pieces.

[0010] The starch-based traditional Chinese medicine decoction pieces include Poria, Chinese Yam, and Trichosanthes Root. It should be noted that the above content is only three preferred commonly used starch-based traditional Chinese medicine decoction pieces, but actually as long as the starch-based traditional Chinese medicine decoction pieces have a sufficient content, they can be used, and generally rhizome decoction pieces are used. The fried leaching traditional Chinese medicine decoction pieces include Astragalus Root, Salvia Miltiorrhiza, and Achyranthes Root. The effective ingredient decomposition traditional Chinese medicine decoction pieces include Licorice Root, Bitter Orange, and Cassia Seed.

[0011] Combined with the first aspect, the present invention provides the second implementation manner of the first aspect, and the reference substances further include volatile oil-based traditional Chinese medicine decoction pieces and resin-based traditional Chinese medicine decoction pieces. Among them, the volatile oil-based traditional Chinese medicine decoction pieces include Mentha and Chuanxiong, and the resin-based traditional Chinese medicine decoction pieces include Frankincense and Myrrh.

[0012] In combination with the first aspect, the present invention provides a third embodiment of the first aspect, wherein the spare decoction pieces material further includes high-fiber Chinese herbal decoction pieces and oil-based Chinese herbal decoction pieces as inert auxiliary materials.

[0013] In combination with the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein when the ball-shaped material is processed into a pellet, the diameter of the pellet is 4 mm to 20 mm; When processing the lump-shaped material into sheets, the diameter of the sheet is 5mm-50mm and the thickness is 1mm-5mm; When the lump-shaped material is processed into blocks, the side length of the blocks is 2mm-20mm.

[0014] In a second aspect, the present invention provides an application method for using the standard decoction piece model prepared by the above-mentioned method for preparing the standard decoction piece model for fire strength testing; First, weigh the standard medicinal material model to the required weight, and then conduct a stir-fry test to determine the fire power range. By controlling the stir-fry time, several groups of stir-fried materials are obtained at different fire power ranges and stir-fry times. Then the stir-fried and roasted food was inspected, first by direct observation to observe the color change of the appearance, and then by cross-section to observe the color change of the medicinal pieces; Then, the extract is determined according to the extract determination method specified in the standard for the selected medicinal material species of the ideal decoction piece; the component content is determined according to the content determination method specified in the standard for the selected medicinal material species of the ideal decoction piece; Finally, determine the optimal firepower and time for the corresponding size, and calculate and confirm the standard fire degree reference table.

[0015] In conjunction with the second aspect, the present invention provides a first embodiment of the second aspect, wherein when inspecting a roasted food, the roasted food is continuously heated, and photographs are taken at set intervals by a camera installed in the open roasting apparatus. The degree of color change of the roasted food is determined based on the photographs using a color algorithm. Simultaneously with the photographs, a predetermined amount of roasted food sample is removed from the open roasting apparatus, cut, and photographed to determine the degree of internal color change. A threshold W for the degree of appearance color change is set. When the degree of appearance color change exceeds the threshold W, the camera device automatically controls to reduce the interval time or shoot video mode and recognizes each frame of image and then makes a judgment and confirmation.

[0016] The beneficial effects of the present invention are: (1) The present invention can provide more reference judgment standards by determining three types and other types of benchmarks based on the three types of Chinese herbal medicine slices.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be further explained below with reference to the drawings and specific embodiments.

[0019] Embodiment 1: This embodiment discloses a preparation method of a standard decoction piece model for fire power test, which is mainly used as a standard processing object for processing experiments when obtaining standard processing time and fire power reference data for traditional Chinese medicine decoction pieces.

[0020] This kind of standard decoction piece model mainly forms a unified external shape, and then by selecting representative decoction piece materials, the processing effects can be referred to from three main characteristics, namely the gelatinization degree, the leaching amount and the content of active ingredients.

[0021] Among them, the gelatinization degree is mainly judged by the change of the appearance state, specifically the color difference before and after heating. Generally, it is directly observed and judged manually. In order to improve the efficiency, a camera device is introduced for efficient judgment to improve the accuracy.

[0022] The leaching amount and active ingredients need to be experimentally analyzed according to the national standard after sampling. During the inspection process, sampling is usually mainly carried out according to the degree of gelatinization stage, and then subsequent sample testing is carried out for each important gelatinization change point to obtain corresponding data for matching analysis.

[0023] Specifically, the preparation method of the standard decoction pieces model is as follows: First, select starch-based traditional Chinese medicine decoction pieces, stir-fried and leached traditional Chinese medicine decoction pieces, and active ingredient decomposition traditional Chinese medicine decoction pieces as the reference substances for gelatinization. After cleaning, classifying and sorting, they are used as spare decoction piece materials. Then, select one or more of the spare decoction piece materials for mixing and carry out drying and pulverization treatment to obtain pulverized materials with a particle size of 1μm - 1000μm in the form of powder or coarse particles. Add the pulverized material to water and mix it evenly to form a mass material. Form the mass material into pills, tablets, and blocks with a unified shape through equipment or manual processing and dry them to form a standard decoction piece model.

[0024] Then, the experimental application method of the fire intensity and processing time using this standard decoction piece model is as follows: First, weigh the required weight of the standard decoction piece model, carry out stir-frying and roasting tests to determine the fire intensity range, and obtain several groups of stir-fried and roasted products by controlling the stir-frying and roasting time within different fire intensity ranges and stir-frying and roasting times. Then, inspect the stir-fried and roasted products. First, observe the change in appearance color by the direct observation method, and then observe the change in the color of the decoction pieces through cross-section observation. Then, according to the leaching substance determination method specified in the standard for the selected medicinal material variety of the ideal decoction pieces, determine the leaching substance; according to the content determination method specified in the standard for the selected medicinal material variety of the ideal decoction pieces, determine the component content. Finally, determine the optimal fire intensity and time under the corresponding dimensions, and calculate and confirm the standard fire intensity reference table.

[0025] As an implementation method, three types of traditional Chinese medicine decoction pieces are selected simultaneously as a comprehensive reference model for preparation, configured with at least 40% of the starch-based traditional Chinese medicine decoction pieces, and the other two are prepared with the same proportion.

[0026] Among them, the starch-based traditional Chinese medicine decoction pieces are Poria cocos, Dioscorea opposita, and Trichosanthes kirilowii Maxim., the stir-fried and leached traditional Chinese medicine decoction pieces are Astragalus membranaceus, Salvia miltiorrhiza, and Achyranthes bidentata Blume, and the active ingredient decomposition traditional Chinese medicine decoction pieces are Glycyrrhiza uralensis Fisch., Aurantii Fructus Immaturus, and Cassia obtusifolia L.

[0027] As an implementation method, the raw materials of the standard decoction piece model only contain starch-based traditional Chinese medicine decoction pieces, and Dioscorea opposita and Paeonia lactiflora Pall. are selected. Since they both belong to rhizome decoction pieces, after drying and pulverization, they form a powdery shape with a fineness of about 100μm, and a spherical standard decoction piece model with a diameter of about 5mm is formed for stir-frying and roasting.

[0028] During the stir-frying process, a large, open stir-frying vessel is set up. A standard heat intensity range corresponding to starch-based medicinal herbs is then set. The stir-frying time range is then determined for each heat intensity point within this range. A camera is then installed above the stir-frying vessel, which not only continuously photographs the material within the vessel but also records high-definition video.

[0029] Set the interval time for taking photos, and obtain photo data in real time through the computer connected to the camera device for image analysis. Use the color difference before and after as the comparison standard, and set the threshold W of the degree of appearance color change. When the degree of appearance color change exceeds the threshold W, the camera device automatically controls to reduce the interval time or shoot video mode and recognize each frame of the image before judgment and confirmation.

[0030] Each time a sample is taken, a quantitative sample is obtained from the roasting apparatus manually or automatically. Each sample is sectioned and photographed for identification. The sample is then stored and other parameters are determined in the laboratory. In this embodiment, no extract is present; only active ingredients other than starch are determined, and roasting then begins.

[0031] Reference Figures 1 - 7 The figure shows the state of the standard medicinal slice model at different time stages. It can be seen that before 180 seconds, the sample had almost no color change, and then after 180 seconds, some local gelatinization occurred. Then, a large number of gelatinization changes began to appear at 220 seconds, and finally at 360 seconds, it almost became a burnt brown state, that is, the entire gelatinization state has exceeded the standard value. In other words, the gelatinization state of starch-based medicinal slices will undergo rapid changes at a certain stage, so setting a change threshold can automatically control the shooting time interval, so that enough pictures can be obtained for analysis and determination during the rapid change period.

[0032] The following table shows the color difference values obtained from the images captured during the experiment. l a b Δl Δa Δb ΔE original drug 45.279 1.179 8.360 20s 46.923 0.970 7.507 1.645 -0.209 -0.853 1.865 40s 51.183 0.977 8.447 5.905 -0.202 0.087 5.909 60s 47.313 0.917 7.307 2.035 -0.262 -1.053 2.306 80s 48.890 0.927 7.803 3.611 -0.252 -0.557 3.663 100s 46.917 0.930 7.273 1.638 -0.249 -1.087 1.981 120s 46.023 0.943 7.130 0.745 -0.235 -1.230 1.457 140s 45.800 1.003 7.537 0.521 -0.175 -0.823 0.990 160s 48.363 1.110 8.717 3.085 -0.069 0.357 3.106 180s 48.423 1.213 9.407 3.145 0.035 1.047 3.315 200s 47.420 1.467 10.080 2.141 0.288 1.720 2.762 220s 42.987 1.713 9.727 -2.292 0.535 1.367 2.722 240s 42.763 2.480 11.233 -2.515 1.301 2.873 4.034 260s 41.887 3.383 12.563 -3.392 2.205 4.203 5.834 280s 39.813 4.023 12.353 -5.465 2.845 3.993 7.342 300s 36.880 4.513 11.027 -8.399 3.335 2.667 9.422 320s 33.967 4.493 8.950 -11.312 3.315 0.590 11.802 340s 34.473 4.420 9.313 -10.805 3.241 0.953 11.321
