Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of stirring treatment, in particular to a method for optimizing earthworm treatment parameters, a treatment method and a preparation method of Qilong Capsules. Background Art
[0002] Earthworms (also known as earthworms) are an important ingredient in Chinese patent medicines. During the production of Qilong Capsules (with astragalus and earthworms as the main raw materials), earthworm treatment is required. In related technical solutions, the specific steps of earthworm treatment are as follows: First step, place fresh earthworms or dehydrated dry earthworms in warm water at 40 degrees Celsius for self-dissolution, and then separate some undissolved earthworm residues from the earthworm solution. The second step requires heating to evaporate the excess water to obtain an earthworm concentrate. The third step is to place the earthworm concentrate in a stirring tank and stir for about 40 - 50 minutes (the specific stirring time varies depending on the batch and source of the earthworms) to obtain a fully foamed earthworm concentrate solution. The fourth step is to transport the foamed earthworm concentrate solution to a continuous belt dryer for drying to obtain plate-shaped earthworms. The fifth step is to crush the plate-shaped solid earthworms into granular form.
[0003] The inventor has learned that during the treatment process of the third step above, through stirring, the earthworm concentrate can be fully mixed with air, and the concentrate will achieve a foaming effect. After foaming, the volume of the earthworm concentrate increases and the density decreases. When it is sent to the subsequent continuous belt dryer for drying, it is convenient to obtain a better drying effect, so that its inside and outside are dried synchronously, and the residue of earthworms on the surface of the belt dryer can be reduced. Specifically, during the stirring and foaming process of the earthworm concentrate, the color of its liquid surface will gradually change from dark brown to light brown, and the volume of the earthworm concentrate will expand. Generally, technicians will visually judge based on the color change of the earthworm concentrate and the proportion of volume expansion to determine the timing of stopping stirring and foaming.
[0004] In the above technical solution, determining the stirring time of the earthworm concentrate by the experience judgment of technicians is limited by the experience judgment, and it is not convenient to obtain a better stirring effect within the shortest stirring time. In addition, for earthworms from different suppliers and different batches, the way of experience judgment by technicians is prone to errors. Summary of the Invention

[0039] To clearly illustrate the technical features of this solution, the present invention will be elaborated in detail below through specific embodiments and in conjunction with its accompanying drawings.
[0040] Embodiment 1
[0041] See Figures 1-4 , one or more embodiments of the present invention provide an earthworm treatment parameter optimization method, including the following steps:
[0042] S1, obtain a sample group of earthworm concentrated liquid to be dried, and the sample group includes multiple samples.
[0043] Specifically, the volume of the earthworm concentrated liquid sample in the sample group here is 5%-15% of the volume of the earthworm concentrated liquid in each stirring treatment during actual production. This setting method is convenient for conducting tests with a smaller volume of samples, reducing the consumption of the earthworm concentrated liquid during the test process. More specifically, the initial volume and mass of each sample are the same to avoid the influence of sample itself differences on the experimental results.
[0044] S2. At different times within a set time interval, stir multiple samples in the sample group respectively. Use the first CCD camera to collect the photos of each sample when the stirring stops, grayscale the photos, and obtain the grayscale values x of different samples. Use the second CCD camera to collect the foaming heights of different samples when the stirring stops, and then obtain the foaming rates y of different samples. Specifically, place the earthworm concentrated liquid in a stirring bucket for stirring and foaming.
[0045] Specifically, referring to the prior art, the optimal stirring time for the earthworm concentrated liquid is generally 40 - 50 minutes. In this embodiment, the number of samples in the sample group is 6 respectively, the set time interval is 40 minutes - 50 minutes, and different samples in the sample group are stirred at intervals of 2 minutes in sequence. More specifically, in the sample group: the stirring time of the first sample is 40 minutes, the stirring time of the second sample is 42 minutes, the stirring time of the third sample is 43 minutes, the stirring time of the fourth sample is 46 minutes, the stirring time of the fifth sample is 48 minutes, and the stirring time of the sixth sample is 50 minutes.
[0046] In order to obtain more sample data, in some other embodiments, the number of samples in the sample group can be 8 or 11 or other values. Taking the number of samples in the sample group being 11 as an example, the stirring time of the first sample is 40 minutes, and the difference in the stirring time between two adjacent samples before and after is 1 minute.
[0047] As mentioned above, in this solution, the first CCD camera is used to collect the photos of each sample when the stirring stops, and the photos are grayscaled to obtain the grayscale value x. Specifically, the photos taken by the first CCD camera here are brown. In the initial stage of stirring, not enough air is mixed into the earthworm concentrated liquid, and it does not foam. The color of the earthworm concentrated liquid is a darker brown. After stirring for 40 - 50 minutes, a large amount of air is mixed into the earthworm concentrated liquid, and the earthworm concentrated liquid foams and becomes light brown.
[0048] Specifically, in this embodiment, the color images taken by the first CCD camera can be grayscale converted using the maximum value method or the average value method according to the RGB values. The obtained grayscale images can be denoised by median filtering or mean filtering. Calculate the average grayscale value of each pixel point of the denoised grayscale image. Take this average grayscale value as the above-mentioned grayscale value x.
[0049] As mentioned above, the second CCD camera is used to collect the foaming heights of different samples when the stirring stops. The second CCD camera needs to cooperate with the scale on the following stirring bucket when in use. First, take a photo of the scale and the earthworm concentrated liquid surface with the second CCD camera, and then use a visual recognition algorithm to obtain the reading of the scale in the photo. The method of using a visual recognition algorithm to obtain the height of the earthworm concentrated liquid surface here can adopt the prior art and will not be elaborated here.
[0050] In some other embodiments, the second CCD camera can be replaced with a laser rangefinder to measure the liquid level height of the earthworm concentrated liquid by using the laser rangefinder. Specifically, the laser rangefinder is set on the top cover of the stirring barrel here, and the laser of the laser rangefinder is emitted and reflected in the direction from top to bottom. In some other embodiments, the scale value on the side wall of the stirring barrel can be visually observed or a separate scale can be inserted into the earthworm concentrated liquid to measure its liquid level height.
[0051] S3. Sequentially convey multiple samples of the sample group to a continuous belt dryer for drying to obtain the solid earthworm output weight α1 corresponding to each sample and the residue weight α2 on the conveyor line of the dryer, and obtain the drying yield of the solid earthworm formed after drying the earthworm concentrated liquid. Specifically, the continuous belt dryer here is a vacuum dryer, which includes a housing in the shape of a pressure tank, and an inner cavity for installing a continuous conveyor belt is formed inside the housing. During actual drying, the thickness of the earthworm concentrated liquid on the surface of the conveyor belt is Ha, and the samples are also laid flat on the upper surface of the conveyor belt with a thickness of Ha for drying.
[0052] Specifically, in the initial stage, the sample is at one end of the conveyor belt close to the feed port. After drying is completed, the conveyor belt conveys the flat earthworm solid to one end close to the discharge port. At this time, a vertical cutter is provided at one end of the belt conveyor line close to the discharge port. After the earthworm solid is output from the end of the belt conveyor line, it will be separated from the conveyor belt in a plate shape, and then every time a certain length of the earthworm solid is output, it can be cut downward by using the cutter.
[0053] S4. Establish the functional relationship of z = f(x), and the functional relationship of z = f(y).
[0054] S5. Respectively obtain the first value range of x and the second value range of y when the drying yield z meets the requirements.
[0055] More specifically, the stirring barrel in this embodiment includes a vertically arranged barrel body 2, the upper end of the barrel body 2 is open, a top cover 3 is installed at the open upper end of the barrel body 2, and the top cover 3 and the barrel body 2 are detachably fixed by a buckle. The lower end of the barrel body 2 is supported by a base 1, a discharge port 10 is provided on the side wall at the lower end of the barrel body 2, and a feed port 6 is provided on the top cover 3. The feed port 6 is used to input the foamed earthworm concentrated liquid into the inner cavity of the barrel body 2, and the discharge port 10 is used to discharge the foamed earthworm concentrated liquid from the inner cavity of the barrel body 2.
[0056] In this embodiment, in S1, the first CCD camera 5 is arranged above the earthworm concentrated liquid to be dried, and the shooting direction of the first CCD camera 5 is vertically downward. More specifically, the first CCD camera here is fixed through the top cover of the stirring barrel. A transparent observation window is provided at the top cover, and the first CCD camera takes pictures of the liquid level inside the stirring barrel through the observation window.
[0057] In this embodiment, in S1, a transparent observation window is provided on the side of the stirring barrel, the second CCD camera 9 is arranged on the side of the observation window, the shooting direction of the second CCD camera 9 is horizontal, and a scale for marking the height of the current earthworm concentrated liquid is arranged on the inner wall surface of the stirring barrel.
[0058] Specifically, the observation window provided on the top cover 3 is the first observation window 4, and the first CCD camera 5 takes a picture of the liquid level of the earthworm concentrated liquid in the inner cavity of the barrel body 2 through the first observation window 4. The observation window at the lower side wall position of the barrel body 2 is the second observation window 8, and the second CCD camera 9 takes pictures of the earthworm concentrated liquid and the scale in the inner cavity of the barrel body 2 through the second observation window 8, and then obtains the height of the current earthworm concentrated liquid according to the image recognition technology.
[0059] More specifically, a guide rod 7 is arranged on the side wall of the barrel body 2, a sliding seat is arranged on the guide rod 7, the sliding seat is driven by an electric push rod 11 to realize lifting, and the above-mentioned second CCD camera 9 is installed on the sliding seat. Furthermore, the second CCD camera 9 is convenient to adjust its shooting range by lifting itself. This setting method enables the second CCD to lift, so as to adapt to the characteristic that the earthworm concentrated liquid rises after foaming.
[0060] In this embodiment, in S3, the residue is the earthworm residue attached to the surface of the conveyor line of the belt dryer. This part of the residue will not naturally separate from the surface of the conveyor belt along with the main part of the fixed earthworms. Instead, it adheres tightly to the surface of the conveyor belt in the form of stubborn residue and needs to be cleaned regularly with a scraper.
[0061] In this embodiment, in S4, a linear function is used to fit multiple values of x and the corresponding values of z to obtain the function z = f(x); a linear function is used to fit multiple values of y and the corresponding values of z to obtain the function z = f(y).
[0062] It can be known that through the drying tests of multiple samples in the sample group, the mapping relationship between x and z, and the mapping relationship between y and z can be obtained. Generally, the higher the foaming rate of the earthworm concentrated liquid, the less the earthworm residue; the smaller the gray value of the photo of the liquid level of the earthworm concentrated liquid, the less the earthworm residue. Therefore, in this embodiment, a monotonic linear function is used to fit the above mapping to obtain the corresponding functional relationship.
[0063] In this embodiment, the foaming rate Among them, h1 is the height of the earthworm concentrated liquid before foaming, and h2 is the height of the earthworm concentrated liquid after foaming. Specifically, before and after the earthworm concentrated liquid foams, the bottom area of the stirring barrel remains unchanged. Furthermore, by using the ratio of the liquid level height difference to the original height, the foaming rate of the earthworm concentrated liquid can be obtained.
[0064] This embodiment also provides a method for processing earthworms, comprising the following steps:
[0065] S10, Place the concentrated earthworm liquid in a stirring barrel.
[0066] S20, Start the stirring shaft of the stirring barrel to stir and foam the concentrated earthworm liquid.
[0067] S30, Use the first CCD camera 5 to monitor the gray value x of the surface photo of the concentrated earthworm liquid, and use the second CCD camera 9 to monitor the foaming rate y of the concentrated earthworm liquid; Stop stirring until the gray value x falls within the first value range and the foaming rate y falls within the second value range.
[0068] S40, Send the foamed concentrated earthworm liquid to a continuous belt dryer to dry it into solid earthworms.
[0069] S50, Crush the solid earthworms into solid particles.
[0070] This embodiment also provides a method for preparing Qilong capsules, comprising the following steps:
[0071] S100, Obtain earthworm granules by using the above-mentioned method for processing earthworms.
[0072] S200, Mix the earthworm granules and astragalus granules according to a set weight ratio.
[0073] S300, Transport the earthworm granules and astragalus granules to a capsule production line to produce Qilong capsules.
[0074] Embodiment 2
[0075] Referring to Embodiment 1, in this embodiment, the sample group has 10 samples, each sample weighs 1 kg, and the drying temperature of the samples in the continuous belt dryer is 45°C - 55°C. The stirring time of each sample plate increases every 1 minute from 40 minutes to 49 minutes. The following are the test data of the stirring time, average gray value of the liquid surface photo, foaming rate, and drying finished product rate of the samples during the sample test process.
[0076]
[0077] The functional relationships of z = f(x) and z = f(y) can be obtained by manual calculation by technicians or by importing the data into a matlab program. In this embodiment, through the automatic fitting and solution of matlab, the functional relationships are as follows:
[0078]
[0079] When the required z is greater than 96%, the optimal value range of x is (97.2, 100.8), and the optimal value range of y is (3.28, 3.31). After the sample test is completed, during the subsequent actual process of stirring, foaming and drying the earthworm extract, when the average gray value x of the earthworm extract obtained by the cooperation of the first CCD camera and the second CCD camera with the subsequent computer image processing is greater than 97.2, and the foaming rate y is greater than 3.28, the stirring can be stopped.
[0080] The above specific implementation manners cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manners of the present invention falls within the protection scope of the present invention. Where the present invention is not described in detail, it is the well-known technology of those skilled in the art of this technology.
