[0002] Hair contains a large amount of keratin, accounting for approximately 65-95% of its composition. Many natural active proteins have a high affinity for hair, are easily absorbed, and have nourishing and film-forming effects, making them excellent hair conditioning agents. The conditioning function of proteins is closely related to their structural composition and molecular weight, the key being the formation of hydrogen bonds with keratin in the hair. Water-soluble proteins, in particular, have a certain repairing effect on damaged hair. Proteins and amino acids are already well-established in hair care products as repairing ingredients for damaged hair.

[0003] Currently, the preparation process of some silanized hydrolyzed proteins involves many steps and requires the use of various equipment in a step-by-step manner. This not only results in a large demand for tools but also in a cumbersome process and insufficient ease of operation. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] See Figures 1-9The silanized hydrolyzed protein preparation method and apparatus provided by this invention includes a tank 1, which consists of a tank body and a tank cover. The tank cover allows for maintenance and replacement of the internal structure of the tank body. Symmetrical feed inlets are provided on both sides of the tank 1. An inlet pipe 2 is welded to the inside of each feed inlet, allowing the solution to enter the tank 1 through the inlet pipe 2. A heating jacket 3 is fitted over the tank 1, which is made of a metal-ceramic composite material, such as an aluminum-based / nickel-based composite material with embedded ceramic particles. The high heat resistance of the ceramic reduces the thermal conductivity of the metal, thereby reducing heat loss. A resistance coil 302 is installed inside the heating jacket 3, and the resistance coil 302 is wound in a ring around the outside of the tank 1. One end of the resistance coil 302 is electrically connected to a power cord 301, which is connected to the power supply. After external power is supplied, current flows through the power cord 301 and the resistor coil 302, generating heat to heat the inside of the tank 1. A mounting bracket 101 is installed at the bottom of the tank 1 to support it. A discharge port is located at the bottom of the tank 1, connected to a drain pipe by welding. An electric push rod 103 is installed at the top of the tank 1. The electric push rod 103 is a device that converts the rotational motion of a motor into linear motion. When the motor is powered on, it generates rotational motion, which is then converted into linear motion of the connecting rod 4 via a mechanical transmission mechanism. The transmission mechanism drives the shaft of the connecting rod 4 to extend or retract, achieving push-pull or lifting functions. The electric push rod 103 mainly consists of the following components: a motor, providing the power source, usually equipped with a reduction gearbox to increase torque; a transmission mechanism: a lead screw, a threaded structure that converts rotational motion into linear motion; gears / belts, used for speed reduction or changing the direction of power transmission; the connecting rod 4 body, including a housing, piston rod, and guide device; and a limit switch, controlling the travel range of the connecting rod 4 and automatically cutting off power when the limit position is reached. Controller: Adjusts the motor's start / stop, direction, speed, or position via feedback from potentiometers, encoders, or Hall sensors.

[0032] The tank 1 is equipped with a stirring assembly for mixing solutions. The stirring assembly includes: a stirring rod 6, which is rotatably connected to the inside of the tank 1, and a pushing member is sleeved on the top of the stirring rod 6; a stirring mechanism, which includes multiple stirring blades 10 evenly arranged around the stirring rod 6, and a torsion member sleeved on one end of the stirring blade 10. Under the action of the torsion member, the deflected stirring blade 10 is driven to return to its original shape; and a pressing mechanism, which is sleeved on the bottom of the stirring rod 6. The pressing mechanism includes multiple sets of fork blocks 603 evenly arranged around the stirring rod 6. When the fork blocks 603 move down, they contact the torsion member and drive the stirring blades 10 to rotate to a horizontal state.

[0033] Furthermore, the pushing component includes: a connecting rod 4, which is slidably inserted into the top of the tank 1; and a connecting plate 402, which has a connecting hole adapted to the stirring rod 6, and the connecting plate 402 is sleeved on the outside of the stirring rod 6.

[0034] Furthermore, the torsion component includes: a torsion spring 1003, which is sleeved on one end of the stirring blade 10 and used to drive the stirring blade 10 to rotate; a fixing plate 1002, which is sleeved on one end of the stirring blade 10 and connected to one end of the torsion spring 1003 by welding on one side, and a stop bar 1001 is provided on the other side of the fixing plate 1002. When the fork block 603 contacts the stop bar 1001, it pushes the stop bar 1001 to drive the stirring blade 10 to rotate to a horizontal position.

[0035] Specifically, the top of the connecting rod 4 is connected to the output end of the electric push rod 103, the top of the stirring rod 6 is connected to the output end of the drive motor 102, the stirring blade 10 is composed of a fan blade and a shaft, and the other end of the stirring blade 10 is slidably connected to the inner wall of the tank 1. When multiple sets of stirring blades 10 rotate to a horizontal state, they will form a plane, which facilitates the application of pressure to the reaction solution when it moves downward, and facilitates filtration. The baffle rod 1001 is set parallel to the stirring blade 10, and the opposite ends of the two baffle rods 1001 are connected to one end arm of the stirring blade 10 by spot welding.

[0036] Furthermore, a telescopic sleeve 1101 is fitted at the bottom of the stirring rod 6, and a spring 11 is provided inside the telescopic sleeve 1101 to elastically restore the initial state.

[0037] Specifically, the telescopic sleeve 1101 has evenly spaced connection holes that are adapted to the stirring blade 10. One end of the stirring blade 10 is rotatably connected to the inside of the connection hole, and the other end of the torsion spring 1003 is spot-welded to the inside of the connection hole. When the rotating rod rotates, it drives multiple stirring blades 10 to rotate circumferentially through the sleeve 601, thereby stirring the silanized hydrolyzed protein and promoting the reaction.

[0038] Furthermore, the bottom end of the connecting rod 4 is connected to a connecting block 401 by welding. A baffle 5 is fitted on the outside of the connecting block 401, which divides the top of the tank 1 into a mixing chamber for mixing solutions.

[0039] Furthermore, the connecting block 401 has a groove on one side of the stirring rod 6 that is compatible with the connecting plate 402, and the connecting plate 402 is rotatably connected to the inside of the connecting block 401.

[0040] Specifically, the baffle 5 is installed in a funnel shape on the top of the tank 1. The bottom of the baffle 5 has a slot. The connecting plate 402 is rotatably connected to the inside of the slot. At the same time, the connecting plate 402 is slidably connected to the stirring rod 6. The outer side of the connecting block 401 is slidably connected to the inner wall of the slot. When the connecting plate 402 is connected to the baffle 5, it plays a sealing role to prevent the mixture from leaking during the mixing process. After the mixture is prepared, the connecting rod 4 is pushed down, and the connecting plate 402 is moved down through the connecting block 401, thereby separating from the baffle 5. The mixture flows out and enters the chamber where the silanized hydrolyzed protein solution is located for mixing and stirring reaction.

[0041] Furthermore, a housing 601 is fitted around the outside of the stirring rod 6, and T rods 602 are uniformly connected to the outside of the housing 601 by welding. During the up-and-down movement of the housing 601, the fork block 603 is driven synchronously by the T rods 602.

[0042] Specifically, the lower side of the same T-bar 602 is connected to two fork blocks 603 respectively. When the housing 601 moves along the outer wall of the stirring rod 6, it drives the fork blocks 603 to move synchronously. The inner diameter of the slot at the bottom of the fork block 603 is adapted to the diameter of the stop rod 1001. When one of the fork blocks 603 contacts the stop rod 1001, it pushes the stop rod 1001 to drive the stirring blade 10 to rotate. When the other fork block 603 contacts the other stop rod 1001, the two ends of the stirring blade 10 are restricted and stop rotating. The principle of the remaining stirring blades 10 is the same. After rotation, all the stirring blades 10 are in a parallel state, forming a circle, which facilitates the subsequent pressing operation.

[0043] Furthermore, a filter membrane 7 is provided at the bottom end of the stirring rod 6. The filter membrane 7 is fixedly installed inside the tank body 1 and is used to filter the mixed liquid.

[0044] Specifically, the filter membrane 7 allows certain substances, such as water and small molecules, to pass through through micropores or chemical properties on its surface, while blocking other substances, such as particles, macromolecules, and ions. The separation mechanisms include: 1. Sieving effect: Separation based on the relative size of the particle size and the membrane pore size, such as microfiltration and ultrafiltration. 2. Dissolution-diffusion mechanism: Substances first dissolve in the membrane material and then diffuse through, such as reverse osmosis and nanofiltration. 3. Charge repulsion: Charged membranes repel ions of the same charge through electrostatic interactions, such as electrodialysis membranes. 4. Affinity adsorption: The membrane surface is modified with specific functional groups to selectively adsorb target substances. By using the filter membrane 7, impurities in the solution after the reaction can be filtered out.

[0045] Furthermore, a slot is provided in the middle of the tank body 1, and a bottom plate 8 is slidably inserted into the slot. A jacket 9 is provided at the bottom end of the bottom plate 8, and an activated carbon layer 901 is provided inside the jacket 9 to decolorize and deodorize the liquid after the reaction.

[0046] Specifically, activated carbon is made from carbonaceous materials such as wood, coconut shells, and coal through high-temperature activation. It possesses a highly developed pore structure of micropores, mesopores, and macropores, with a specific surface area reaching 500~1500 m² / g. This structure provides a large number of adsorption sites. Activated carbon adsorbs pigments and odor molecules such as organosulfur compounds and benzene compounds through weak electrostatic attraction (van der Waals forces) between molecules, and is particularly effective for small molecules with molecular weights <300 Da. Oxygen-containing functional groups on the surface of activated carbon, such as carboxyl, hydroxyl, and carbonyl groups, can chemically bond or react with polar molecules such as aldehydes and hydrogen sulfide, enhancing the adsorption of specific substances. Some odor molecules, such as ammonia and formaldehyde, may be catalytically oxidized into harmless substances on the surface of activated carbon. Activated carbon is targeted at decolorization and deodorization. For decolorization, it mainly adsorbs large molecular colored substances such as dyes and humic acids, relying on the sieving effect of micropore and mesopore size. Deodorization: For volatile organic compounds, sulfides, aldehydes, etc., the adsorption efficiency is affected by molecular polarity and boiling point. High boiling point substances are more easily adsorbed.

[0047] A method for preparing silanized hydrolyzed protein includes the following steps:

[0048] Step 1: First, add 0.1 mol / L hydrochloric acid as a catalyst to propylmethylsilanediol (or propylsilanetriol) through the central inlet pipe 2 into tank 1. The mixing ratio of hydrochloric acid to propylmethylsilanediol is 1:3. Hydrochloric acid activates the hydroxyl groups, promoting the condensation reaction.

[0049] Step 2: After the solution is mixed, start the electric push rod 103, push down the pusher, open the notch of the baffle 5, and the mixed liquid flows into the next chamber of hydrolyzed protein solution to react with it to obtain crude product silanized hydrolyzed protein solution. During the reaction, the inside of the tank 1 is heated by the resistance coil 302 to keep the inside of the tank 1 at 60-80℃, and the final pH of the system is adjusted to 5-7 to obtain crude product silanized hydrolyzed protein solution. At the same time, start the drive motor 102, and drive the stirring blade 10 to rotate through the stirring rod 6 to make the hydrolyzed protein solution react fully with the hydrochloric acid-propylmethylsilanediol mixture. The reaction time is 4-8 hours.

[0050] Step 3: After the reaction, the bottom plate 8 is pulled out, and then the connecting rod 4 is pushed down. Through the connecting block 401, connecting plate 402 and casing 601, multiple fork blocks 603 are moved down synchronously and come into contact with the stop rod 1001, causing the stirring blade 10 to rotate to a horizontal position. As the connecting rod 4 continues to descend, the horizontal stirring blade 10 descends, applying pressure to the crude product silanized hydrolyzed protein solution after the reaction, causing it to be filtered through the filter membrane 7 and fall into the next chamber. The filtered silanized hydrolyzed protein solution comes into contact with activated carbon and is decolorized and deodorized using the activated carbon layer 901. Then it is concentrated and sterilized to obtain silanized hydrolyzed protein, which is then discharged through the drain pipe.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
