<p>Production of a water-in-oil emulsion that is stable over a long period, while the amount of surfactant added is kept to a minimum, will be possible. An apparatus is configured with an oil passageway (1), an oil supply means (P1) that supplies oil to the oil passageway maintaining a constant flow rate and that also generates a turbulent flow zone in the oil passageway (1), a water supply passageway (4) that merges into the turbulent flow zone (1a) in the oil passageway (1), a water supply means (P2) that supplies water at a constant flow rate to the water supply passageway (4), a surfactant supply passageway (7) that merges into the water supply passageway (4), a surfactant supply means (P3) that supplies surfactant at a constant flow rate to the surfactant supply passageway (7), an oil and water dispersing zone (A) created at the point where the turbulent flow zone (1a) in the oil passageway (1) and the water supply passageway (4) merge, and an impact effect zone (C) provided on the downstream side from the oil and water dispersing zone (A). A fluid subjected to impact in the impact effect zone (C) is discharged as an emulsion.</p> |
