  "description_excerpt": "The disclosure relates to the field of fluidization devices, and more particularly to a powder rotary fluidization device and a method thereof.\n\nSome powder has loose properties and thus can flow freely. Some powder has strong adhesion and thus is easily to be adhered together so that is difficult to flow. The flowability of powder is one of important properties of powder, which is of great significance for pharmaceutical works. For example, powder packaging, capsule filling, tablet pressing and dosage distribution and the like are all affected by the flowability of powder. Only the powder flows, subsequent powder treatment processes such as mixing, drying, rounding, surface modification and the like can be carried out. An existing fluidized bed can solve some of problems associated with the flowability of powder, but has a poor effect for fine powder with high viscosity. Therefore, it is necessary to provide a powder rotary fluidization device and a method thereof, so as to solve at least some of the problems in related art.\n\nA series of simplified concepts are introduced in the summary section, which will be further described in detailed in embodiments of the disclosure. The summary of the disclosure is not intended to define key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.\n\nIn order to solve at least some of the above problems, embodiments of the disclosure provide a powder rotary fluidization device and a method thereof.",
