Ultra fine bubble generator, ultra fine bubble generation method, and ultra fine bubble containing liquid

摘要

PROBLEM TO BE SOLVED: To provide a UFB generation apparatus capable of efficiently producing a highly pure UFB-containing liquid within a target generation time by controlling the production of UFB in a liquid. SOLUTION: A UFB generator 1A drives a target concentration setting means 6000 for setting a target concentration of an ultrafine bubble contained in a liquid and a heat generating element 10 to cause a film to boil in the liquid to generate an ultrafine bubble. The driving means 2000, the generation time setting means 6001 for setting the target generation time required to generate a predetermined amount of liquid having the target concentration, and the ultrafine bubble generation speed according to the target concentration and the target generation time. It includes a control means 1000 that controls the drive means so as to adjust. [Selection diagram] FIG. 12
