RACK FOR REGENERATING AGENT

PROBLEM TO BE SOLVED: To provide a rack capable of evenly freezing a sheet-like regenerating agent with high efficiency.SOLUTION: The hanger rack 40 has a structure in which a plurality of substantially portal supporting frames 45 having a hanging frame 46 capable of hanging a sheet-like regenerating agent 1 in a double-fold manner and extending in the longitudinal direction are juxtaposed on a body frame 41 with the prescribed spacing. The two sheet-like regenerating agents 1 are longitudinally juxtaposed, and hanged from and supported by a hanging part 46 of each supporting frame 45. An area on the distal side of the hanging frame 46 forms a horizontal part 48 in the horizontal posture, and an area on the proximal side forms an inclined part 47 having the downhill gradient toward the distal side. The sheet-like regenerating agent 1A on the distal side is hanged in a downwardly straight posture with respect to the horizontal part 48, and the sheet-like regenerating agent 1B on the proximal side is hanged in a diagonal posture toward the distal side while being partly overlapped with respect to the inclined part 47.
