Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figs. 1-2 A rapid neutralization device for cystine production is a highly efficient and flexible production equipment, mainly used for acid-base neutralization reactions in the cystine production process. By precisely controlling the reaction conditions, it ensures that the neutralization reaction is rapid, uniform, and stable, thereby improving the production efficiency and product quality of cystine.

[0023] Specifically:

[0024] The device includes a fixed support 1 for providing stable support for the entire device. A neutralization tank 2 for cystine production is installed on the fixed support 1. The neutralization tank 2 serves as the main container for the neutralization reaction, capable of holding the reactants and carrying out the neutralization reaction. Preferably, the neutralization tank 2 is cylindrical to facilitate material mixing and reaction, and its inner wall is smooth for easy cleaning and maintenance. A heat exchange jacket 3 is fitted on the outside of the neutralization tank 2 to facilitate temperature regulation of the neutralization tank 2. Circulating water is circulated to regulate the temperature of the neutralization tank 2, ensuring that the neutralization reaction takes place at a suitable temperature.

[0025] To facilitate the input of neutralizing agents (such as acids and bases) into neutralization tank 2, an input pipe 11 is installed at the top of neutralization tank 2, and an output pipe 12 is installed at the bottom of neutralization tank 2 to facilitate the discharge of the neutralized filtrate from neutralization tank 2.

[0026] A neutralizing cylinder 4 is installed in the neutralizing tank 2 for input of cystine hydrolysate, and a plurality of filter holes 6 are arranged on the neutralizing cylinder 4, so that the neutralizing cylinder 4 is in communication with the neutralizing tank 2, thereby facilitating mixing and neutralization reaction of the cystine hydrolysate and the neutralizing agent, and meanwhile, the filter holes 6 can also filter the cystine hydrolysate, so that the filter residue can be blocked in the neutralizing cylinder 4. Preferably, the neutralizing cylinder 4 is in a spherical shape as a whole.

[0027] A feeding pipe 5 is installed on the top of the neutralizing cylinder 4, so as to facilitate input of the cystine hydrolysate. Preferably, a funnel 9 for facilitating feeding is also installed on the feeding pipe 5. A discharging pipe 7 is installed on the bottom of the neutralizing cylinder 4, so as to facilitate output of the filter residue.

[0028] Secondly, the feeding pipe 5 penetrates the top of the neutralizing tank 2 from the inside to the outside and extends to the outside of the neutralizing tank 2. The discharging pipe 7 penetrates the bottom of the neutralizing tank 2 from the inside to the outside and extends to the outside of the neutralizing tank 2. A rotary dynamic seal 10 is installed on the neutralizing tank 2 at the joint of the feeding pipe 5 and the discharging pipe 7 and the neutralizing tank 2, which not only ensures the sealing of the neutralizing tank 2, but also enables the feeding pipe 5 and the discharging pipe 7 to rotate relative to the neutralizing tank 2.

[0029] A driving device 8 for driving the feeding pipe 5 to rotate the neutralizing cylinder 4 is also installed on the neutralizing tank 2, which provides power for rotation of the neutralizing cylinder 4, so that the neutralizing cylinder 4 rotates and the efficiency of the mixing and neutralization reaction is improved. Preferably, the driving device 8 is a speed reducer motor. The motor shaft of the speed reducer motor is in transmission connection with the feeding pipe 5, and transmission gears that are in mesh with each other are installed on the motor shaft of the speed reducer motor and the feeding pipe 5.

[0030] In order to further improve the efficiency of the mixing and neutralization reaction, a plurality of transversely arranged stirring rods 13 are also installed on the neutralizing cylinder 4, which promote mixing of the materials and ensure uniform mixing of the materials in the neutralizing tank 2.

[0031] In order to monitor the temperature and pH value in the neutralizing tank 2 in real time and ensure that the neutralization reaction is carried out under suitable conditions, a temperature instrument and a pH meter are also installed on the neutralizing tank 2.

[0032] In actual use, an input control valve is installed on the input pipe 11, an output control valve is installed on the output pipe 12, a feeding control valve is installed on the feeding pipe 5, and a discharging control valve is installed on the discharging pipe 7, so as to facilitate control of input and output of the materials.

[0033] The specific working process of the device is as follows:

[0034] I. Preparation

[0035] Ensure that the neutralization tank 2, heat exchange jacket 3, input pipeline 11, output pipeline 12, neutralization cylinder 4, feed pipeline 5, discharge pipeline 7 and other components are intact and have no leakage phenomenon;

[0040] III. Add raw materials

[0041] Open the feed control valve on the feed pipeline 5, and add cysteine hydrolysate (cysteine hydrolysate is obtained by biochemical process from raw materials containing cysteine such as hair) into the neutralization cylinder 4 through the hopper 9. The raw materials are evenly distributed in the neutralization cylinder 4 along with the rotation of the neutralization cylinder 4;

[0042] Open the input control valve on the input pipeline 11 and add an appropriate amount of neutralizing agent into the neutralization tank 2;

[0043] IV. Neutralization reaction

[0044] The rotation of the neutralization cylinder 4 and the action of the stirring rod 13 make the cysteine hydrolysate and the neutralizing agent fully mix and stir in the neutralization tank 2, promoting the progress of the neutralization reaction. At the same time, the heat exchange jacket 3 adjusts the temperature of the neutralization tank 2 to ensure that the reaction is carried out at an appropriate temperature;

[0045] Monitor the temperature and pH value in the neutralization tank 2 in real time through the temperature instrument and pH meter, and adjust the temperature setting of the heat exchange jacket 3 and the amount of neutralizing agent according to the monitoring results to ensure that the neutralization reaction is carried out under appropriate conditions;

[0046] V. Discharge material

[0047] When the neutralization reaction is completed, first close the speed reducer motor to stop the rotation of the neutralization cylinder 4, then open the output control valve to output the filtrate from the output pipeline 12, and then open the discharge control valve on the discharge pipeline 7 to discharge the filter residue from the neutralization cylinder 4;

[0048] Collect the discharged material and carry out subsequent processing according to the production requirements;

[0049] VI. Cleaning and maintenance

[0050] After production is completed, the neutralization tank 2, neutralization cylinder 4, input pipeline 11, output pipeline 12 and other components are cleaned to remove residues, ensuring the cleanliness and hygiene of the equipment.
