This kind of chemical product does not require a drug production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for drug synthesis. In the process of pharmaceutical intermediate drying equipment, the obtained pharmaceutical intermediate drying equipment solution needs to be separated and purified, and then further dried in order to obtain high-purity and high-quality target products.

[0003] For example, application number CN202223505591.7 The utility model discloses a pharmaceutical intermediate drying equipment, including a base body, a column is provided on the base body, a drying room is provided on the column, a feeding device and a heating device for providing heat for the drying room are provided on the drying room, a motor is provided on the drying room, a rotating shaft is provided for rotating motor one, a dispersion plate and a distribution plate are provided in the drying room, a dispersion plate and a support arm connected to the rotating shaft are rotatably provided on the dispersion plate, a brush is provided on the support arm, a screen is provided at the bottom of the dispersion plate, a distribution plate is provided below the dispersion plate in the drying room, a scraper connected to the rotating shaft is rotatably provided on the distribution plate, and a distribution hole is provided at the bottom of the distribution plate. The advantages of the utility model compared with the prior art are: it can disperse the materials of the intermediate drying equipment to prevent the materials from clumping and thus being heated unevenly, avoid the adhered materials from being dried for a long time and denaturing and affecting the product quality, prolong the contact time between the materials and the hot air, and ensure that the materials are dried more thoroughly.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that although the above equipment can solve the problem that the intermediate drying equipment is transported and dried at the same time, which easily leads to material clumping, thereby causing uneven heating of the surfaces of the materials in the intermediate drying equipment, affecting the uniformity of the intermediate drying equipment, and the product cannot be fully exposed to the hot air flow, thereby affecting the drying efficiency and effect of the product. At the same time, the material adhering to the inner wall of the drying cylinder is in contact with the high-temperature heating device for a long time, which easily leads to the degeneration of the intermediate drying equipment and affects the product quality. At the same time, when the material of the intermediate drying equipment is dried, its contact time with the hot air is short, which reduces the drying efficiency. However, during use, the material is discharged and dried through a spiral discharge pipe. During the discharge process of the spiral discharge pipe, the material will adhere to the inner wall of the spiral discharge pipe, which will not only affect the normal discharge of the spiral discharge pipe, but also cause the spiral discharge pipe to be blocked. There are certain limitations. Utility Model Content
