[0002] As a relatively precious Chinese medicinal material, tortoise shell glue has been widely used in the field of traditional Chinese medicine due to its high medicinal value. Tortoise shell glue is a solid glue made by processing the plastron and carapace of testudinidae animals through multiple processes. It consumes a large amount of raw materials for tortoise shells and has a low output, so it is relatively precious. Most manufacturers of tortoise shell glue in the prior art use traditional processes to process the plastron and carapace of testudinidae animals through multiple processes, resulting in different quality of the final tortoise shell glue products, and lack of intelligent process technology for stable extraction of tortoise shell glue. In addition to the existing tortoise shell glue extraction process, the whole piece of finished tortoise shell glue is generally cut into tortoise shell glue cubes with a thickness of 8 mm. The drying cycle of tortoise shell glue cubes of this specification is long, and the moisture content is also high. It is inevitable that the composition standard in the tortoise shell glue cubes is lower than the pharmacopoeia standard, resulting in unnecessary waste of raw materials. Summary of the invention

[0003] In view of the above problems, the present invention is proposed to provide a new preparation process of tortoise shell glue that overcomes the above problems or at least partially solves the above problems, which can realize the automated and intelligent extraction of tortoise shell glue and process it into cubes, thereby ensuring the quality of the finished tortoise shell glue cubes and avoiding the waste of raw materials.

[0009] S5 concentration: low-temperature concentration of the tortoise shell glue after separation and impurity removal in step S4 to reduce damage to the collagen in the tortoise shell glue;

[0010] S6: mixing the tortoise shell glue concentrated in step S5 to further improve the light transmittance and product quality of the tortoise shell glue;

[0011] S7: Cutting the tortoise shell glue after the total mixing in step S6; the thickness of the tortoise shell glue after cutting is set to 1mm-8mm;

[0012] S8: drying the glue: drying the tortoise shell glue diced in step S7 to obtain tortoise shell glue dices that meet product specification requirements.

[0013] Optionally, the intelligent extraction device is configured to automatically control various index parameters in the extraction process to ensure the stability of the extracted tortoise shell glue.

[0014] Optionally, the index parameters include at least extraction temperature parameters, time parameters, and pressure parameters to reduce instability caused by human operation.

[0015] Optionally, the step S5 includes: the low-temperature concentration process is carried out using a double-effect vacuum low-temperature concentration device to reduce damage to the effective ingredients in the tortoise shell glue.

[0022] S23 drying: using a high-speed centrifugal device to wash the tortoise shell in step S22 to ensure the cleanliness of the surface of the tortoise shell.

[0023] Optionally, the tortoise shell raw material in step S1 is the tortoise shell of Chinese grass tortoise over 3 years old.

[0024] In the preparation process of a novel tortoise shell glue of the present invention, an intelligent device is added to the preparation process, and the stable parameter setting of the intelligent device ensures the reasonable use of the tortoise shell raw materials while increasing the quality stability of the finished tortoise shell glue. By improving the dicing process of the finished tortoise shell glue and adding an automatic dicing device, tortoise shell glue products of different specifications can be obtained, which makes it easier to meet the standard requirement that the component standard of tortoise shell glue diced is higher than the pharmacopoeia standard, so as to meet the diverse needs of users.

[0033] The embodiment of the present invention provides a novel preparation process of tortoise shell glue, comprising the following steps:

[0034] S1 Material selection: Select tortoise shell raw materials to ensure the production quality of finished tortoise shell glue from the source.

[0035] S2 pretreatment: pretreatment of the tortoise shell raw material selected in step S1 to ensure that the tortoise shell raw material is clean, free of impurities and odor.

[0041] S8: drying the glue: drying the tortoise shell glue diced in step S7 to obtain tortoise shell glue diced in accordance with product specification requirements.

[0042] In a new tortoise shell glue preparation process of an embodiment of the present invention, since an intelligent device is introduced to participate in the entire process flow of tortoise shell glue preparation, by setting the stable parameters of the intelligent device, the quality stability of the finished tortoise shell glue is increased while ensuring the rational use of the tortoise shell raw materials. First, S1 material selection, by strictly checking the tortoise shell raw materials, the production quality of the finished tortoise shell glue is guaranteed from the source. Further, by selecting and breeding by building a self-built tortoise and deer breeding base, and accumulating experience in cooperation with scientific colleges and universities, the selection and breeding ensures the quality of raw materials. Further, in terms of the control of tortoise shell suppliers, they must be legal enterprises that have been registered and approved by relevant national departments and have corresponding production or business qualifications, or comply with national industrial policies, can trace the source of the products, and can provide certification documents. S2 pretreatment, through this step, the selected tortoise shells are further processed to ensure that the tortoise shell raw materials are clean, free of impurities and odor. S3 extraction, mainly the operation of extracting tortoise shell glue from the pre-treated clean tortoise shell, this step is mainly carried out by an intelligent extraction device. By setting the extraction parameters of the intelligent extraction device in advance, the entire tortoise shell glue extraction process becomes more intelligent, more stable, and more efficient, avoiding the errors caused by manual participation, and forming a standardized extraction process. S4 separation and impurity removal, mainly using a high-speed separation device to separate and remove impurities from the extracted tortoise shell glue, further removing the grease and fine impurities in the glue liquid, making the glue liquid clearer and more transparent. S5 concentration, low-temperature concentration of the tortoise shell glue after separation and impurity removal, to reduce the damage to its collagen by high-temperature concentration, effectively extending the concentration time. S6 total mixing, the total mixing process is mainly to improve the transmittance and product quality of tortoise shell glue. S7 cutting glue, the semi-finished tortoise shell glue completed by the above steps needs to be further processed and diced to facilitate the subsequent packaging and listing of packaging bags. In the market, tortoise shell glue is generally cut into different thicknesses of glue dices, and the cutting thickness is generally set to 1mm-8mm. S8 glue drying, the diced tortoise shell glue is dried. After the tortoise shell glue is diced, it needs to be further dried to obtain the final tortoise shell glue dices. Intelligent devices are involved in the entire tortoise shell glue preparation process. Through the stable parameter setting of the intelligent device, the quality stability of the finished tortoise shell glue is increased while ensuring the rational use of the tortoise shell raw materials.

[0043] Furthermore, in response to the problems of low intelligence level and low efficiency of automated equipment in the existing tortoise shell glue preparation process, the company jointly built the country's first intelligent production line for tortoise shell glue with Aerospace Cloud Network, using a large number of new equipment and new processes, and utilizing automation, informatization, and intelligent technologies to achieve the leap from traditional tortoise shell glue production methods to intelligent production.

[0044] In some embodiments of the novel tortoise shell glue preparation process of the present invention, step S2 includes: S21 impurity removal, S22 cleaning and S23 drying. The tortoise shell is cleaned by a tortoise shell impurity removal device to remove the rotten meat and rotten oil on the tortoise shell to ensure that the tortoise shell is clean and free of physical impurities. The tortoise shell is dynamically cleaned online by a cleaning device to further remove impurities on the surface of the tortoise shell. The tortoise shell in step S22 is washed by a high-speed centrifugal device to ensure the cleanliness of the surface of the tortoise shell.

[0045] In this embodiment, preferably, a self-developed tortoise shell dry impurity removal machine is used to remove impurities (tortoise shell meat oil) from the raw materials to ensure that the raw materials are clean and free of impurities. The tortoise shell dry impurity removal machine has the characteristics of thorough cleaning, high efficiency, and low pollution. The quality of raw material processing directly affects the quality of the product. After the rotten meat and rotten oil of the tortoise shell are thoroughly processed, the fishy smell or peculiar smell of the tortoise shell glue can be effectively removed.

[0046] Furthermore, a self-developed horizontal cleaning machine is used for online dynamic cleaning, which allows the raw materials to rub against each other and remove impurities on the surface of the tortoise shell.

[0047] Furthermore, the cleaned tortoise shell raw material is spun and washed using a high-speed sling centrifuge to remove excess soaking and washing water contained on the tortoise shell, thereby achieving further cleaning of the tortoise shell raw material.

[0048] In some embodiments of the novel tortoise shell glue preparation process of the present invention, the intelligent extraction device is configured to automatically control various index parameters during the extraction process to ensure the stability of the extracted tortoise shell glue.

[0049] In this embodiment, the intelligent extraction device is an intelligent extraction cabinet, and the use of an intelligent extraction cabinet to extract tortoise shell glue is a national first. In the process of extracting tortoise shell glue, the intelligent extraction cabinet automatically controls all technical parameters such as extraction temperature, extraction time, and extraction pressure, reducing the instability of the operation. In the process of extracting tortoise shell glue, the temperature of the production process directly affects the stability of the quality of the tortoise shell glue product. Through the application of the intelligent extraction cabinet, it plays an important and key role in the extraction of tortoise shell glue, further increasing the utilization rate of raw materials and the extraction efficiency of tortoise shell glue, and ensuring the quality of the finished tortoise shell glue.

[0050] Furthermore, in some embodiments of the novel tortoise shell glue preparation process of the present invention, the extraction index parameters of the intelligent extraction cabinet include at least extraction temperature parameters, time parameters, and pressure parameters to reduce the instability caused by human operation.

[0051] Specifically, the intelligent extraction process of tortoise shell glue is generally divided into three times. Among them, the detailed index parameters involved in the first extraction are: insulation for 4 to 6 hours, temperature control between 110℃ and 115℃, and intelligent extraction cabinet cavity pressure control between 0.065 and 0.080MPa. The detailed index parameters involved in the second extraction are: insulation for 3 to 5 hours, temperature control between 110℃ and 115℃, and intelligent extraction cabinet cavity pressure control between 0.065 and 0.080MPa. The detailed index parameters involved in the third extraction are: insulation for 2 to 4 hours, temperature control between 110℃ and 115℃, and cavity pressure control between 0.065 and 0.080MPa. After the extraction is completed, the glue is pumped into the sedimentation tank through a bag filter, and after precipitation, it is transferred to the storage tank through a stainless steel multi-layer filter.

[0052] In some embodiments of the novel tortoise shell glue preparation process of the present invention, a high-speed separation device is used to separate and remove impurities from the tortoise shell glue extracted in the step S3. In this embodiment, the preferred high-speed separation device is an improved three-stage high-speed butterfly separator, which performs high-speed separation on the extracted glue to remove grease and fine impurities in the glue, making the glue clearer and more transparent.

[0053] In some embodiments of the novel tortoise shell glue preparation process of the present invention, step S5 includes: the low-temperature concentration process is carried out using a double-effect vacuum low-temperature concentration device to reduce the instability caused by human operation.

[0054] In this embodiment, the low-temperature concentration process is mainly carried out using a double-effect vacuum low-temperature concentration device. By vacuum low-temperature concentration of the extracted tortoise shell glue solution, the damage to collagen caused by high-temperature concentration is reduced, the concentration time is effectively extended, and the collagen molecules in the tortoise shell glue solution are more fully hydrolyzed, and the protein molecules are hydrolyzed from large molecules into small molecules, which are more conducive to human absorption.

[0055] In some embodiments of the novel tortoise shell glue preparation process of the present invention, the total mixing process in step S6 is carried out using a vacuum concentration device; the vacuum concentration device has an intelligent temperature control system to achieve full temperature control of the tortoise shell glue.

[0056] In this embodiment, the total mixing process of the tortoise shell glue liquid is intended to improve the light transmittance and product quality of the tortoise shell glue. The process used in the middle mainly involves low temperature control throughout the process, and the temperature in the total mixing process needs to be controlled in real time. The total mixing process is carried out by using a vacuum concentration tank independently developed to realize the intelligent display of the process temperature, reduce the total mixing time, and further improve the light transmittance and product quality of the tortoise shell glue product.

[0057] In some embodiments of the novel tortoise shell glue preparation process of the present invention, step S7 includes: dicing the tortoise shell glue by an automatic dicing device to make the obtained diced glue more uniform in shape. The automatic dicing device is configured to automatically adjust the thickness of the diced glue according to demand.

[0058] In this embodiment, the dicing device is mainly used to dice the above-mentioned semi-finished tortoise shell glue. Traditional dicing is mainly done by manpower, the degree of automation is not high, and the shape of the finished tortoise shell glue dices is not uniform. By developing a CNC one-piece dicing machine for cutting glue, the shape of the obtained glue dices is more uniform and more intelligent. Furthermore, the CNC one-piece dicing machine can adjust the thickness of the dices according to customer needs, and can meet the needs of different customers for tortoise shell glue dices.

[0059] Furthermore, in some embodiments of the novel tortoise shell glue preparation process of the present invention, the thickness of the tortoise shell glue after cutting is preferably set to 2 mm in step S7.

[0060] In this embodiment, the company's R&D personnel conducted multiple experiments and found that the tortoise shell glue cubes were cut into 2mm thick cubes. Due to the small size of the cubes, the drying cycle was greatly shortened, and the water evaporated faster and more evenly during the drying process. After testing, the moisture content was 30% lower than that of the 8mm cubes on average, the solid content was higher, the melting time was shorter, and the disintegration speed was faster. Among them, the experimental data after the measurement are as follows Figure 1 , Figure 2 As shown in Table 1 and Table 2:

[0061] Through statistical analysis of inspection data of 6 batches of 2mm tortoise shell glue cubes and 24 batches of normal batches of tortoise shell glue, the average moisture content of 2mm tortoise shell glue cubes was 23.9% lower than that of normal batches of tortoise shell glue (8mm cubes and blocks), and 44.7% lower than the pharmacopoeia standard.

[0064] Depend on Figure 1 , Figure 2 As can be seen from Table 1, the novel tortoise shell glue preparation process of the present invention introduces intelligent and automated processing technology, so that the final tortoise shell glue cubes have better quality ingredient content when they are 2mm in size. The average moisture content of 2mm tortoise shell glue cubes is 23.9% lower than that of normal batches of tortoise shell glue (8mm cubes and blocks), and 44.7% lower than the pharmacopoeia standard; the amino acid content is 50% higher than that of normal batches of tortoise shell glue (8mm cubes and blocks), which is more advantageous.

[0066]

[0067] In some embodiments of the novel tortoise shell glue preparation process of the present invention, the tortoise shell raw material in step S1 is selected from the tortoise shell of Chinese tortoise over 3 years old.

[0068] In this embodiment, the selection of better quality tortoise shell raw materials is the basis for ensuring the finished tortoise shell glue. Based on the material selection standards of "raw material control starts from seed selection" and "good raw materials and good quality", all the tortoise shell raw materials used by the company are selected from Chinese grass tortoise shells over 3 years old, and strictly control the supplier selection, raw material acceptance and production material feeding, and establish the "Turtle Shell Acceptance Management Regulations". The Quality Management Department leads the acceptance, supervises the entire acceptance process, strictly controls the key points of the acceptance link, and is responsible for the authenticity and quality of the raw materials. During the initial inspection, the supplier and the acceptance team members are present, and the tortoise shells are inspected bag by bag. The acceptance process establishes strict acceptance standards in terms of safety, appearance, and variety source. In order to ensure the quality of tortoise shell glue products, the Quality Department conducts standardized management of tortoise shell production and feeding. The Quality Management Department strictly leads the acceptance of raw materials in accordance with the acceptance process, communicates in time for tortoise shells with problems, and proposes treatment opinions for sites that do not meet the requirements.
