The utility model relates to an efficiency of reaction of hydroxypropyl starch is improved device belongs to modified starch processing equipment technical field. It comprises reation kettle, spray assembly, and its characteristics are: installing agitator, upper portion in the reation kettle and opening the system and have mounting hole, bottom export to install total valve, pipeline connection valves a, valve b are respectively crossed to the main valve gate open, spray assembly's the pumping over incoming end that sprays has valve b through piping erection, and spray that the pumping over output connects through pipeline and multi pack at least two spray that the ball passes through the pipeline, the mounting hole is installed in reation kettle. The realization is handled epoxypropane's circulation atomizing, guarantees that starch milk and gasification epoxypropane fully contact, simple structure, and installation, convenient operation, the sexual valence relative altitude improves epoxypropane's utilization ratio greatly, effectively shortens production reaction time, and it is few with the epoxypropane contact to have solved the prior art starch milk, leads to the fact the epoxypropane utilization ratio low, and greatly increased reaction time results in the low problem of hydroxypropyl starch epoxypropane 1.
