Technical Field

[0002] Niacinamide, also known as nicotinamide, is an amide compound of nicotinic acid. It is a white crystalline powder and is mainly used as a skin conditioner in cosmetics. Supramolecular VC niacinamide is a complex that combines vitamin C (VC) and niacinamide. This complex is widely used in the medical and beauty fields, such as whitening skin, fading spots, improving skin texture, promoting wound healing, and enhancing immunity.

[0003] Application No. CN202220786385.9 discloses a crystal precipitation device, including a casing, wherein a cooling chamber and a filter box are sequentially arranged inside the casing from top to bottom. By sequentially arranging the cooling chamber and the filter box from top to bottom inside the casing, an array of guide plates are sequentially arranged inside the cooling chamber from top to bottom, and the array of guide plates inside the cooling chamber are alternately arranged with discharge ports on the left and right. After the material enters the cooling chamber, it flows downward alternately on the left and right inside the cooling chamber. The heat conducting plates arranged on the inner walls on the left and right sides of the cooling chamber are cooled after the semiconductor refrigeration plate is powered on, and the flowing material is cooled. During this period, the throttle plate arranged on the guide plate can slow down the flow speed of the material and improve the cooling efficiency of the material. The filter cylinder arranged can intercept the crystals when the material is crystallized, and water flows out from the holes of the filter arc plate. The crystals of the chemical material are pushed to the discharge port by the guide screw shaft. The device integrates crystallization and solid-liquid separation, has a simple structure, and is easy to operate.

[0004] When the crystallization device in the existing and above technologies is used, the flowing material is cooled and crystallized by cooling, and then sent to the discharge port through the spiral shaft. However, the crystals easily clog the holes of the filter arc plate, so that the water cannot flow out in time and is transported to the discharge port by the spiral shaft. This will cause excessive water to be mixed in the crystals, affecting the crystallization effect. Therefore, in view of the above problems, a eutectic cooling and crystallization device for the production of supramolecular VC niacinamide is proposed. Utility Model Content

[0034] It also includes a cleaning mechanism and a limiting mechanism for cleaning the crystals on the surface of the filter plate 5;

[0035] The cleaning mechanism comprises a driving motor 3, which is a servo motor.

At the same time, the sleeve ring 7 on the surface of the threaded shaft 9 slides on the surface of the threaded shaft 9. At the same time, the threaded shaft 9 drives the connecting rod 6, and the connecting rod 6 drives the brush head 21 to clean the surface of the filter plate 5, thereby avoiding the clogging of the filter plate 5, affecting the filtering effect of the filter plate 5, and avoiding the crystals from clogging the holes of the filter arc plate, so that the water cannot flow out in time, and is transported to the discharge port by the spiral shaft, resulting in excessive water mixed in the crystals, affecting the crystallization effect.

At the same time, the plug rod 17 will also squeeze the gear rod 18, so that the gear rod 18 drives the rotating rod 19 to rotate, and drives the impact pad 20 to rotate at the same time. When the retaining ring 8 is reset, the plug rod 17 is separated from the gear rod 18, so that the torsion spring drives the rotating rod 19 to reset, so that the impact pad 20 hits the scraper 10, and the debris on the surface of the scraper 10 is shaken off to avoid accumulation.
