Abstract

See full text

Disclosed is a drying device for a hollow fiber membrane, including: a tubular drying member that is formed with an opening portion through which a hollow fiber membrane is input and output at at least one end thereof in a length direction, the hollow fiber membrane passing inside the tubular drying member while forming a gap between the hollow fiber membrane and an inner circumferential surface of the tubular drying member; and a gas supply unit that is formed on a side surface of the tubular drying member and supplies a drying gas into the tubular drying member. Thus, it is possible to dry the hollow fiber membrane in a short time at a low cost without the necessity of large equipment.
