[0031] Reference Figure 1 and Figure 3 In the present application, a screening plate 2 is arranged in the middle of the reactor body 1. After the powder enters the reactor body 1 through the feed port 10, it is screened by the screening plate 2 and the bulk powder is discharged from the discharge port 11 for collection and re-crushing. The screened powder passes through the screening plate 2 and enters the bottom of the reactor body 1 to mix and react with the liquid amino acid raw material through the liquid inlet 12. The rotating shaft 31 of the stirring component 3 is connected to the output end of the motor 30. The motor 30 drives the rotating shaft 31 to rotate, and the amino acid raw material and the powder are uniformly stirred, while reducing the mixing time, accelerating the reaction rate, and improving the work efficiency.

[0032] Meanwhile, the rotation of the rotating shaft 31 has no influence on the screening, and the cross-section of the screening plate 2 is formed into a trapezoid, which is conducive to the transportation of large-block powder to the discharge port 11.

[0033] In some preferred embodiments, a first stirring rod 32 and a second stirring rod 33 are provided on the upper portion of the outer circumference of the rotating shaft 31, the first stirring rod 32 and the second stirring rod 33 correspond to each other, a plurality of pointed protrusions 320 are provided on the outer circumference of the first stirring rod 32, the end of the second stirring rod 33 is connected to the scraper assembly 4, and the end of the scraper assembly 4 away from the second stirring rod 33 contacts the inner wall of the reactor body 1. The first stirring rod 32 and the second stirring rod 33 are located above the sieve plate 2.

[0034] Specifically, the upper part of the rotating shaft 31 is provided with a first stirring rod 32 and a second stirring rod 33. During the stirring process of the powder by the first stirring rod 32 and the second stirring rod 33, on the one hand, the pointed protrusions 320 provided break the incoming powder for the second time, and on the other hand, a scraping operation is performed on the powder adhered to the inner wall of the reactor body 1, so that the powder is completely used for the reaction processing of amino acid raw materials.

Similarly, the scraping assemblies 4 arranged at the ends and bottoms of the stirring blades 34 are mainly used for scraping the reactants adhered to the inner wall of the reactor body 1, and at the same time, they are thoroughly cleaned during the subsequent cleaning process to avoid affecting the next use. At the same time, the scraping assembly 4 located at the bottom end of the stirring blade 34 scrapes the bottom of the reactor body 1.

[0037] In some preferred embodiments, the scraping assembly 4 includes a sleeve 40 and a connecting rod 41 located inside the sleeve 40. The connecting rod 41 is connected to a scraper 42.

Adaptive scraping can be performed according to the thickness of the material adhered to the inner wall, improving the reuse of the scraping assembly 4.

[0039] Embodiment 2

[0040] This Embodiment 2 is implemented on the basis of Embodiment 1. A water cavity 15 is arranged between the inner wall and the outer wall of the reactor body 1. A cleaning assembly 5 is arranged on the outer wall of the reactor body 1. The cleaning assembly 5 includes a heating water tank 50. A first water inlet pipe 53 is arranged at the top of the heating water tank 50, and the first water inlet pipe 53 is communicated with the water cavity 15. A second water inlet pipe 54 is also arranged at the top of the heating water tank 50, and the second water inlet pipe 54 is communicated with an annular diversion pipe 51 located at the top of the reactor body 1. The annular diversion pipe 51 is adjacent to the inner wall of the reactor body 1 and is provided with a plurality of spray heads 52. The spray heads 52 are inclined towards the inner wall of the reactor body 1.

[0041] Specifically, referring to Figure 2 , a heating device is provided inside the heating water tank 50 to make the heating device work to meet the temperature requirements during the processing of amino acid raw materials. It is connected to the water chamber 15 in the reaction kettle body 1 through the first water inlet pipe 53 to provide the temperature requirements for the processing of amino acid raw materials and accelerate the reaction rate of amino acid raw materials. At the same time, it is connected to the annular diversion pipe 51 located at the top of the reaction kettle body 1 to clean the reaction kettle body 1 from which the reaction liquid is discharged after processing. During the cleaning process, the spray head 52 always sprays towards the inner wall of the reaction kettle body 1 to thoroughly clean the materials adhered to the inner wall without affecting the reaction of the next amino acid raw material.

[0042] In some preferred embodiments, a recovery pipe 55 is provided at the bottom of the water chamber 15 and communicated with the bottom of the heating water tank 50. Pressure pumps 56 are respectively provided on the first water inlet pipe 53, the second water inlet pipe 54, and the recovery pipe 55.

[0043] Specifically, the recovery pipe 55 can recover the water in the water chamber 15 to the heating water tank 50 for heating under the action of the pressure pump 56 for secondary recycling. After being heated and processed in the heating water tank 50, it is then transmitted into the water chamber 15 through the first water inlet pipe 53 under the action of the pressure pump 56. The water in the water chamber 15 is always under a certain temperature condition, thus meeting the temperature requirements for the reaction of amino acid raw materials. At the same time, a water inlet is also provided in the heating water tank 50 to facilitate replenishing water and heating the heating water tank 50, so that the heated water in the water chamber 15 is always under a certain temperature condition.

[0044] The working principle of the present utility model is as follows: The powder material enters the upper part of the reaction kettle body 1 through the feeding port 10. At this time, the rotating shaft 31 starts to work, driving the first stirring rod 32, the second stirring rod 33, and the stirring blades 34 to rotate. Before screening, the powder material will contact the pointed protrusions 320 provided in the first stirring rod 32 to make the powder material broken twice. After being screened through the sieve holes 21 of the screening plate 2, the powder material drops to the lower part of the reaction kettle body 1, and the powder material that has not been screened is collected through the discharge port 11. The heated water in the heating water tank 50 enters and exits the water chamber 15 through the first water inlet pipe 53 under the action of the pressure pump 56, making the internal environment of the reaction kettle body 1 present a certain temperature condition. Then, the liquid amino acid raw material is mixed with the powder material inside the reaction kettle body 1 through the liquid inlet 12. Under the action of the stirring blades 34 and scraping, the reaction rate is accelerated and the reaction time is shortened. After the reaction is completed, it is discharged and collected through the liquid discharge port 13. At the same time, the pressure pump 56 connected to the second water inlet pipe 54 is started, so that the water in the heating water tank 50 enters the reaction kettle body 1 through the annular diversion pipe 51 and the spray head 52. The spray head 52 is arranged towards its inner wall, so that the water sprays precisely on the inner wall of the reaction kettle body 1, thus thoroughly cleaning the inner wall.

Based on the technical essence of the present utility model, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present utility model still fall within the protection scope of the technical solution of the present utility model.
