Description

Technical Field

[0001] This invention relates to a device and process for preparing keratin silk peptide nanoemulsion for pet hair repair, belonging to the field of keratin silk peptide preparation technology. Background Technology

[0002] The main drawbacks in the emulsification stage of existing keratin silk peptide nanoemulsion preparation processes for pet hair repair include low emulsification efficiency, poor emulsion stability, and uneven particle size distribution. These drawbacks are typically related to the choice of emulsifier, emulsification process parameters, and the properties of the raw materials. Poor compatibility between the selected emulsifier and keratin silk peptides, or improper control of parameters such as stirring speed, time, and temperature during emulsification, will lead to unsatisfactory emulsification results. Conventional solutions include optimizing the selection of emulsifiers and adjusting emulsification process parameters. For example, choosing emulsifiers with better compatibility with keratin silk peptides, or determining the optimal stirring speed, time, and temperature through experiments. However, these methods have the disadvantage of potentially requiring extensive experimentation to screen for optimal conditions, which is time-consuming, labor-intensive, and costly. Pet hair repair products are affected by various external factors, such as temperature changes, light exposure, and chemical substances, which can further affect the stability and effectiveness of the emulsion. Therefore, there is an urgent need for a new equipment for preparing keratin silk peptide nanoemulsions for pet hair repair to address these issues. Summary of the Invention

The pretreatment component uses a spiral centrifugal valve body with an internal centrifugal vane assembly to efficiently emulsify and dialysis keratin raw materials. The negative pressure environment ensures material flow stability. The buffer centrifugal component is connected to the separation and freezing system via a constant pressure sealed guide tube, ensuring the molecular structure integrity of the nanoemulsion during phase inversion.

The cooling liquid nitrogen recovery pipe has a set of drying and retention components at the lower middle position for the emulsified keratin and silk peptide substances. In actual use, the relevant personnel use a guide motor to drive the guide auger to send the material into the emulsification mixing chamber through a right-angle guide path. The magnetically controlled guide screw promotes the uniform mixing of keratin and acetic acid solution with a 15-20mm spiral inclined surface. The main tank adopts a flange-sealed double-connecting wing structure, which, together with the side response chamber door, enables operation visibility. The vacuum compression freezing device and the liquid nitrogen cooling pipe form a gradient cooling system, allowing the material to complete the phase change in the range of -40℃ to -196℃. The inner turbulence roller creates a turbulent flow field inside the guide screw and effectively improves the freezing efficiency. The drying and retention components realize the recycling of liquid nitrogen through the condensate air recovery pipe.

The right end of the inner channel pipe is provided with a control module for controlling the release degree of the refrigerant compression tank, the flow effect of the flow interruption control valve, and the liquid nitrogen recovery effect of the inner channel control valve. The control module is connected to the flow interruption control valve, the refrigerant compression tank, and the inner channel control valve via wires. The inside of the inner channel pipe is provided with several sets of diversion inner cavities for diverting liquid nitrogen. Each set of diversion inner cavities is provided with a filter for trapping and filtering impurities inside the liquid nitrogen. The inner permeation mesh, with its internal flow-blocking holes for liquid nitrogen flow and filtration, forms a double-sealing structure with the sealing ring and the outer locking seat in practical use, ensuring the airtightness of the liquid nitrogen delivery pipeline. The inner channel control valve and the flow-off control valve work together to regulate the flow of the refrigerant. The refrigerant compression tank distributes liquid nitrogen evenly to the pressure-resistant pipe through a three-part distribution pipe. The sealing inner liner effectively prevents low-temperature leakage. The control module integrates and manages the entire refrigeration cycle, monitoring the refrigerant release, recovery, and filtration process in real time. The inner permeation mesh in the distribution cavity can intercept impurities with a particle size greater than 5μm, ensuring the purity of the refrigerant and thus providing a stable low-temperature environment for the preparation of keratin nanomaterials.

[0016] A preparation process for a device for preparing keratin silk peptide nanoemulsion for pet hair repair includes the following steps: S1: First, the crude keratin raw material is centrifuged to obtain the supernatant and dialyzed to remove salt, and keratin silk peptides are obtained. Then, keratin and silk peptides are dissolved in 0.1 mol / L acetic acid solution at a mass ratio of 3:1 to form an 8% protein aqueous phase. Span80 and Tween80 are compounded at an HLB value of 10.5 and mixed with cyclohexane at a volume ratio of 1:4. S2: During the mixing process, the aqueous phase is slowly dripped into the organic phase under magnetic stirring, and the temperature is maintained at 35-42℃. Then, it is circulated three times under 45MPa pressure by a high-pressure homogenizer to form a colostrum with a particle size of 60-75nm. S3: Liquid nitrogen is compressed using a refrigerant compression tank, then released into the main tank and cooled with the keratin emulsion to be emulsified. After centrifugation and collection of the precipitate, 0.1% trehalose is added for freeze-drying protection, while simultaneously completing phase inversion drying. Then, the temperature is lowered to -40℃ at a rate of 1℃ / min and maintained for 2 hours, followed by drying at -55℃ and 10Pa for 24 hours. The final product has a water content of ≤5% as the basic standard.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are as follows: by integrating modules such as pretreatment, centrifugal separation, and freeze drying, continuous preparation of keratin silk peptide nanoemulsion is realized. The pretreatment component adopts a centrifugal valve body with a spiral spiral structure and an inner centrifugal blade assembly, which can efficiently complete the emulsification and dialysis of keratin raw materials. The negative pressure environment ensures the stability of material flow. The buffer centrifugal component is connected to the separation and freezing system through a constant pressure sealed guide tube, so that the nanoemulsion maintains the molecular structure integrity during the phase transformation process. The separation and freezing component adopts gradient cooling technology and, together with the condensate air recovery system of the drying and retention component, can effectively retain the active ingredients of keratin and improve the stability of the emulsion. Motor 1 drives the main drive roller via belt to rotate the centrifugal mixing core, enabling the keratin raw material in the feed centrifuge tank 1 to complete primary nano-emulsification in the hollow structure. Positioning bearings and side stabilizing support plates ensure operational stability. The seepage chamber and lower guide pipe 1 guide the primary emulsion into the primary recovery box for preliminary separation. The inner sealing side plug prevents material leakage and maintains a negative pressure environment. The secondary centrifuge tank achieves secondary centrifugation by motor 2 driving the main drive roller 2. Its internal static chamber, combined with the centrifuge outlet controlled by the electric heating wire, can adjust the separation accuracy. The sealed space formed by the connecting conduit and the guide pipe can maintain the stability of the material phase. The secondary recovery pipe enables continuous collection of products. This design allows keratin molecules to be gradually refined during the two centrifugation processes. The electric heating system can precisely control the separation temperature to avoid protein denaturation. Efficient emulsification is achieved through a roller structure and annular centrifugal flow channel design. The embedded holes and drive shaft work together to ensure stable power transmission. The annular flow holes promote the axial circulation of the keratin solution. The swivel maintains rotational balance. The centrifugal blades supported by arc-shaped arms form a multi-stage annular flow channel, causing the material to generate a spiral shearing motion under centrifugal force. This improves the emulsification uniformity by more than 30% compared to traditional stirring methods. The internal flow centrifugal annular cavity structure can avoid local eddies and ensure that the particle size distribution of the nanoemulsion is controlled within a reasonable and effective range. The relevant personnel use a guide motor to drive the guide auger to send the material into the emulsification mixing chamber through a right-angle guide path. The magnetically controlled guide screw promotes the uniform mixing of keratin and acetic acid solution with a 15-20mm spiral inclined surface. The main tank adopts a flange-sealed double-connection wing structure, which, together with the side response chamber door, enables operation visibility. The vacuum compression freezing device and liquid nitrogen cooling pipe form a gradient cooling system, which enables the material to complete phase change in the range of -40℃ to -196℃. The internal turbulence roller creates a turbulent flow field inside the guide screw and effectively improves freezing efficiency. The drying and interception component realizes liquid nitrogen recycling through the condensate air recovery pipe. The sealed bearing ensures the continuous operation stability of the system under low temperature conditions. The sealing connection ring and the outer locking seat form a double sealing structure to ensure the airtightness of the liquid nitrogen delivery pipeline. The inner channel control valve and the flow cut-off control valve work together to regulate the flow of the refrigerant. The refrigerant compression tank distributes liquid nitrogen evenly to the pressure-resistant pipe through a three-part distribution pipe. The sealing inner liner effectively prevents low-temperature leakage. The control module integrates and manages the entire refrigeration cycle, and monitors the refrigerant release, recovery and filtration process in real time. The inner permeation mesh in the distribution cavity can intercept impurities with a particle size greater than 5μm, ensuring the purity of the refrigerant, thereby providing a stable low-temperature environment for the preparation of keratin nanomaterials.

[0018] The beneficial effects of this process after adopting the above technical solution are as follows: This process prepares 60-75nm nanoemulsions through high-pressure homogenization technology, which significantly improves the skin permeability of keratin silk peptides and enhances the hair repair effect. The optimized emulsifier compound and gradient freeze-drying technology work together to protect protein activity. The addition of trehalose effectively maintains the stability of the nanoemulsion. Liquid nitrogen freeze-drying combined with precise temperature control ensures that the final product has a water content of ≤5%, which preserves the function of repair factors for a long time, improves pet hair dryness and sensitivity problems, and restores the skin microecological balance.

Then, it is circulated three times under 45MPa pressure by a high-pressure homogenizer to form a colostrum with a particle size of 60-75nm. S3: Liquid nitrogen is compressed using a refrigerant compression tank 84, and then released into the main tank 76. The liquid nitrogen is then cooled with the keratin emulsion to be emulsified. After centrifugation and collection of the precipitate, 0.1% trehalose is added for freeze-drying protection, while phase inversion drying is completed.

S3: Use a refrigerant compression tank (84) to compress liquid nitrogen, then release the liquid nitrogen into the main tank (76) and cool it down with the keratin emulsion to be emulsified. After centrifugation and collection of precipitate, add 0.1% trehalose for freeze-drying protection and complete phase inversion drying. Then, first lower the temperature to -40℃ at a rate of 1℃ / min and keep it for 2 hours, and then dry it at -55℃ and 10Pa for 24 hours. The final product has a water content of ≤5% as the basic standard.
