Motivated by the drying pattern experiment by Yamazaki and Mizuguchi [J. Phys. Soc. Jpn. 69 (2000) 2387], we propose the dynamics of sweeping interface, in which material distributed over a region is swept by a moving interface. A model based on a phase field is constructed and results of numerical simulations are presented for one and two dimensions. Relevance of the present model to the drying experiment is discussed.
