Hot air filtering system for solid medicine production

The utility model relates to the technical field of pharmaceutical engineering, in particular to a hot air filtering system for solid medicine production, which comprises a drying tower, a hot air generator assembly, a stirring assembly and a driving assembly, the drying tower is used for drying solid medicine, the upper end of the drying tower is communicated with a feeding assembly, and the lower end of the drying tower is communicated with a discharging assembly. The hot air generator assembly is used for conveying hot air into the drying tower, and the stirring assembly is arranged in the drying tower and used for fully stirring solid medicine. Hot air is conveyed into the drying tower through the hot air generator assembly, impurities in the air are filtered out, the stirring rod and the spiral stirring blades are driven by the driving assembly to alternately rotate forwards and backwards, a plurality of solid medicines are driven to roll over and move, and hot air enters the stirring barrel through the
