PROBLEM TO BE SOLVED: To provide a device for dehydrating jellyfishes landed in quantities, by a weight loaded on top of the jellyfish layers. SOLUTION: An uncovered treatment vessel 1 is connected with a drainpipe 1a holding a drain valve 1b at the lower end of the sidewall, and an uncovered inside vessel 2 by a plurality of supporting members 2c on the bottom of the treatment vessel. The side wall 2a and the bottom is supported 2b of the inside vessel are made of porous materials to communicate with the outside facemember through the materials, and the inner face of the inside vessel is made to form a flexible reticular surface. The jellyfishes 6 are laid on the bottom bed of the inside vessel uniformly by handwork to form a loading layer of jellyfishes at the bottom, and pressing members 3 made of a tabular and porous body covering the jellyfish layers and forming a reticular surface and the jellyfish layers are alternately overlaid. Further a weight 4 hung by a rope 5b of adjustable tension through a pulley 5a from a winch 5 is put on the uppermost pressing member.
