LIQUID REMOVAL APPARATUS AND LIQUID REMOVAL METHOD

[Object] To provide a liquid removal device capable of removing liquid on a steel sheet without using wringer rolls and a drier. [Solution] A liquid removal device that removes liquid attached to a surface of a sheet-like member that moves relatively, the liquid removal device including: a slit nozzle that jets gas to the surface of the sheet-like member; and a gap measurement device that measures a gap between a jetting port of the slit nozzle and the sheet-like member. The slit nozzle is installed so as to jet gas from a downstream side toward an upstream side in a movement direction of the sheet-like member that moves relatively to the slit nozzle, and is configured in a manner that a jet angle ¸, a back face inclination angle ², a back face length L of a nozzle back face, a gap h, a slit width d, and nozzle pressure P n of the slit nozzle satisfy the following relational formulas.
