IMMEDIATELY-BEFORE-STIRRING-TYPE FLUID PROCESSING DEVICE AND PROCESSING METHOD

摘要

Provided are an immediately-before-stirring-type fluid processing device and an immediately-before-stirring-type fluid processing method that can adjust or improve the final properties of a fluid to be processed that is introduced as a raw material into an annular flow channel of a microreactor employing the annular flow channel, which is formed between relatively rotating processing surfaces, as a flow channel in which fluid processing is performed. A fluid to be processed, which has been prepared in a fluid preparing system P so as to be in an ideal state for reaction, is charged into a fluid processing device F. The fluid processing device F subjects the fluid to be processed to reaction processing in an annular flow channel 3, which is formed between two processing surfaces 1, 2. A cylindrical stirring space 51 is provided in the radially inner side of the annular flow channel, and a rotor 61 and a screen 71 are disposed inside the stirring space 51. Stirring energy is applied by the rotor 61 and a shearing force is applied between the rotor 61 and the screen 71 to the fluid to be processed immediately before the fluid to be processed is introduced into the annular flow channel 3.
