PROBLEM TO BE SOLVED : To provide a vacuum fermentation dryer that can efficiently remove odor produced from an article to be treated, prevent diffusion of smell to surroundings and further prevent deterioration by a corrosive component produced from the article to be treated.SOLUTION : The vacuum fermentation dryer 1 includes : a dryer 2 having a treatment chamber 22 to which an organic article to be treated added with microorganisms is thrown in; a heating jacket 24 arranged in the dryer 2, which heats the article to be treated; a heating agitation part 25 rotatably disposed in the treatment chamber 22 of the dryer, which heats and also agitate the article to be treated; a condensation part 23 for condensing steam generated from an organic waste to generate condensed water; a gas-liquid separator 3 into which a mixture of the condensed water of the condensation part 23 and air in the treatment chamber 22 is introduced and which separates the introduced mixture into the condensed water and air; and a suction pump 5 connected to a downstream side of the gas-liquid separator 3, which sucks the condensed water of the condensation part 23 and the air in the treatment chamber 22 toward the gas-liquid separator.
