Technical Field

[0001] The utility model relates to the technical field of material drying devices, in particular to a 6S-5-methyltetrahydrofolate calcium drying device. Background Art

[0002] 6S-5-methyltetrahydrofolate is a new type of folic acid drug. It is well known because it is often used as the main ingredient of nutritional supplements and food additives. 6S-5-methyltetrahydrofolate can directly participate in many important biochemical reactions in the body, can prevent symptoms such as Alzheimer's disease and cellular anemia, and has important pharmacological effects. Compared with other drugs, 6S-5-methyltetrahydrofolate has the characteristics of significant efficacy, complete functions and few side effects, and has gradually become the focus of common concern in the fields of medicine and pharmaceutical research. Since 6S-5-methyltetrahydrofolate has extremely low solubility in water and poor bioavailability, its calcium salt is generally used in medical and health care applications.

[0003] However, the stability of 6S-5-methyltetrahydrofolate calcium is poor, and it is particularly highly sensitive to oxygen, so there are special requirements for its synthesis, drying and packaging. In particular, the drying process of the product has a huge effect on the final quality control of the product. Due to the use of conventional inert atmosphere (such as nitrogen) drying, due to uneven heating, the product temperature near the heating wall is too high, thereby hardening and yellowing occur, which greatly affects the quality of the product, and the drying process is intermittent production, which greatly affects production efficiency. How to solve the above problems and improve the quality and production efficiency of the product has become a problem in the 6S-5-methyltetrahydrofolate calcium drying process. Utility Model Content

The rotating shaft is driven to rotate by two driving motors, and the conveyor belt can be driven to transport while the rotating shaft rotates, so that the material moves left and right on the conveyor belt and falls downward, which is conducive to the dispersion of the material.

[0007] Preferably, the bottom of the tank body is in a bucket-shaped structure, and a viewing window is embedded on one side of the bottom of the tank body. The viewing window is made of transparent tempered glass, and the material inside the tank body can be easily observed through the viewing window.
