An air-cooling drop pill production line comprises a drop pill system, an air-cooling circulation system and a control system. The drop pill system comprises a molten material tank and a dripper. A vibration apparatus is arranged between the molten material tank and the dripper, and drives the dripper to vibrate up and down. A vibration shear force cuts liquor flowing out from the dripper into drops, and drop pills are formed after the drops fall into the air-cooling circulation system and are cooled. An online monitoring apparatus is arranged on the dripper, and comprises a pulse signal emission mechanism with an emission frequency which is the same as a vibration frequency of the vibration apparatus. The control system controls and regulates a dropping parameter according to a monitoring result of the online monitoring apparatus. The present invention combines vibration dropping, online monitoring and controlling, air cooling, and fluidized drying and coating together, which satisfies the requirement of high-speed dropping, micro pill preparation and improving a drug-loading capacity. Thus, the drug-loading capacity of drop pills can be multiply improved, the usage of auxiliary materials and the dosage can be greatly reduced, organic solvent residual can be completely avoided, and requirements of different processes including slow-release coating, film coating and sugar coating can be satisfied.
