Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a medicine tablet coating machine. Background Art

[0002] Tablet coating machine is a kind of equipment widely used in the pharmaceutical industry, mainly used for the sugar coating production of pills and tablets. The working principle of the tablet coating machine is to form a uniform coating layer by spraying slurry material (such as syrup) on the rotating pills or tablets.

[0003] During use, the existing coating machine usually sprays the slurry material onto the rotating tablets through a spray system, and then takes out the tablets. However, there is moisture on the surface of the tablet sugar coating, and removing the medicine can easily cause impurities to adhere to the coating layer, and it can also easily cause the coating layer to deform, affecting the coating effect of the tablets. In addition, the tablets are usually coated inside a rotating container, which is inconvenient to disassemble and clean the container, which can easily cause the medicine to remain inside the container, affecting the subsequent tablet coating effect.

[0004] Therefore, it is necessary to provide a new medicine tablet coating machine to solve the above-mentioned technical problems. Utility Model Content
