[0021] The embodiments described below are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Referring to Figure 1 and Figure 2 The present embodiment provides a crystalline trehalose recrystallization device, which comprises a frame 10 and a crystallization kettle 20. The crystallization kettle 20 is horizontally arranged on the top of the frame 10. One end of the bottom of the crystallization kettle 20 is rotatably connected with the frame 10 through a rotary assembly 30. A telescopic assembly 40 is arranged between the other end of the crystallization kettle 20 and the frame 10. A driving assembly 50 is arranged on one side of the crystallization kettle 20 close to the telescopic assembly 40. An output end of the driving assembly 50 is connected with a rotary shaft 60. The rotary shaft 60 extends into the crystallization kettle 20. Stirring blades 70 are arranged on the outside of the rotary shaft 60. Flexible scrapers 80 are arranged on the side of the stirring blades 70 away from the rotary shaft 60. A first cooling pipe 90 and a second cooling pipe 100 are spirally arranged on the outside of the crystallization kettle 20. The first cooling pipe 90 and the second cooling pipe 100 are both provided with an inlet and an outlet. The inlet and the outlet of the first cooling pipe 90 and the second cooling pipe 100 are arranged in opposite directions. That is, the inlet of the first cooling pipe 90 is arranged on the side close to the driving assembly 50, the outlet of the first cooling pipe 90 is arranged on the side away from the driving assembly 50, the inlet of the second cooling pipe 100 is arranged on the side away from the driving assembly 50, and the outlet of the second cooling pipe 100 is arranged on the side close to the driving assembly 50. The bottom of the side of the crystallization kettle 20 close to the rotary assembly 30 is arranged as a discharge port 21. A liquid outlet is arranged on the bottom of the crystallization kettle 20. A filter screen is arranged on the liquid outlet.

[0023] Preferably, the stirring blades 70 are provided with filter holes 71. The filter holes 71 can make part of the material pass through the filter holes 71 during stirring, thereby effectively reducing the direct interference between the stirring blades 70 and the material during stirring. Not only can the stirring resistance be reduced to make the stirring process smoother, but also the problems of material caking or damage to the crystalline form caused by excessive stirring can be avoided.

[0024] Preferably, the rotating assembly 30 is a hinge. By using a hinge as the rotating assembly 30, the stable rotation of the crystallization kettle 20 can be achieved, and unnecessary vibration or damage of the material during rotation can be avoided.

[0025] Preferably, the telescopic assembly 40 is an electric telescopic rod, and the two ends of the electric telescopic rod are connected to the crystallization kettle 20 and the rack 10 through the rotating shaft 60, respectively. The setting of the electric telescopic rod makes the height of one side of the crystallization kettle 20 adjustable as needed, providing more flexible operability. Through the control of the electric telescopic rod, the lifting position of the crystallization kettle 20 can be accurately adjusted, so that the position of the discharge port 21 is lower, facilitating the collection and discharge of the material. In another preferred mode, the telescopic assembly 40 is a hydraulic cylinder.

[0026] Preferably, the driving assembly 50 is a driving motor. Through the adjustment of the driving motor, the stirring speed can be accurately controlled, and the material mixing and crystallization quality in the crystallization process can be optimized.

[0027] Preferably, the top of the crystallization kettle 20 is provided with a pressurized air port 23, and the pressurized air port 23 is detachably connected to a pressurizing device. During discharging, high-pressure air is introduced through the pressurized air port 23, which can effectively push the material in the crystallization kettle 20 out quickly. The use of high-pressure air not only can speed up the discharge speed of the material, but also can avoid the long residence of the material in the crystallization kettle 20, thereby improving the production efficiency.

[0029] Preferably, the flexible scraper 80 is in contact with the inner side wall of the crystallization kettle 20. The setting of the flexible scraper 80 makes it closely adhere to the inner side wall of the crystallization kettle 20, effectively cleaning the material attached to the inner wall during crystallization. It can prevent the accumulation of crystallized material on the inner wall, reduce the accumulation of material in the crystallization kettle 20, and thereby avoid the situation of blockage or uneven crystallization.

[0030] Preferably, the inner side wall of the crystallization kettle 20 is provided with a vibrator at the bottom. The setting of the vibrator can not only provide moderate vibration during the crystallization process, promote the uniform distribution and crystallization of the material, but also assist the discharge of the material. Specifically, the vibrator generates a vibration wave, which makes the material at the bottom of the crystallization kettle 20 more loose, reduces the adhesion and accumulation of the material, and effectively promotes the smooth discharge of the crystallized material from the discharge port.

[0031] Preferably, the inner side wall of the crystallization kettle 20 is provided with a temperature sensor. The temperature sensor can monitor the temperature change in the crystallization kettle 20. By detecting the temperature, it can be ensured that the crystallization process is adjusted within the optimal temperature range, thereby improving the crystallization efficiency and product purity. At the same time, the setting of the temperature sensor can prevent the negative effects of excessively high or low temperature on the crystallization process, avoid unevenness or excessive crystallization during the crystallization process, and ensure the stability of the quality and crystallization form of the material.

[0032] The utility model provides a kind of crystalline trehalose recrystallization device, including a rack 10 and a crystallization kettle 20. The crystallization kettle 20 is placed horizontally, and inside is provided with stirring blade 70, and stirring blade 70 is stirred to material during recrystallization, so that material can be fully stirred, avoid the problem of general crystallization quality, efficiency caused by uneven stirring (the existing reaction kettle is vertically arranged, and the material at the bottom cannot be stirred).

In addition, the first cooling pipe 90 and the second cooling pipe 100 spirally arranged outside the crystallization kettle 20 realize efficient convection cooling through the water inlet and outlet in opposite directions, ensure that the temperature distribution in the kettle is uniform, so as to optimize the crystallization effect and improve the product purity. When the material crystallization is completed, the telescopic assembly 40 drives the crystallization kettle 20 to lift, so that the discharge port 21 is located at a lower position, and the discharge can be more easily. Therefore, the crystalline trehalose recrystallization device is designed by efficient stirring, cooling, cleaning and discharging, which not only improves the recrystallization efficiency, but also improves the product quality after recrystallization.
