Production process for manufacturing solid-phase povidone iodine

The invention discloses a production process for manufacturing solid-phase povidone iodine. The production process is characterized in that: the raw materials used in the preparation process comprise 80 to 84.5 percent by weight of povidone K30 and 20 to 15 percent by weight of iodine; before the povidone iodine is subjected to a complex reaction, actual water content of the povidone raw materialis detected first and then the water content of the povidone K30 is increased to between 4 and 8 percent by a method for accurately measuring and adding pure water into the povidone raw material and evaporating the pure water to make the pure water adsorbed by the povidone; and the temperature range of the complex reaction is between 50 and 95 DEG C and the time of the complex reaction is between25 and 36 hours. The technical scheme of the invention can guarantee that the effective iodine content of the excellent povidone iodine reaches over 10.6 percent and the stability of solution of the excellent povidone iodine i
