PURPOSE: A vacuum absorption dehydrator is provided to increase dehydration efficiency by controlling interval between vacuum nozzles according to width of fabric. CONSTITUTION: A vacuum absorption dehydrator makes a vacuum nozzle contact with the inner wall of a perforated drum by installing a vacuum pipe body and a vacuum nozzle between frames (20) at both sides and additionally installing the perforated drum (50) allowing rotation on the outer surface and make dehydrated by vacuum absorbing power of the vacuum nozzle with a fabric passing through the top of the perforated drum. A concaved groove is formed in an absorption hole of the vacuum nozzle and enables the control of vacuum absorbing width in the vacuum nozzle. A guide ring and a perforated drum gear are formed at both ends of the perforated drum and rotates being combined with a drive gear (55).
