PROBLEM TO BE SOLVED: To provide a drying method for a surfactant paste providing high drying efficiency. SOLUTION: A cylindrically formed inner wall surface of a drying tank 1 is used as a heat transfer surface 2, and the surfactant paste is put in the drying tank 1. The surfactant paste wound upward from below while rotating rotation blades 9 journalled to a bottom face center of the drying tank 1, the surfactant paste is pressed against the heat transfer surface 2 by centrifugal force following rotation of the rotation blades 9, and drying of the surfactant paste is carried out while evaporating moisture included in the surfactant paste by heat transferred from the heat transfer surface 2.
