A food fermenter mainly formed by a main chamber comprising an evaporation chamber therein, and a fermentation chamber, where said fermentation chamber includes a first water tank therein and a second water tank connected in a fluid manner with the first water tank, said second water tank being supplied by said first water tank and configured for having a smaller size than the first water tank a heat emitting source supplied by gas or electricity is arranged under the second water tank for providing heat thereto, at least a heat exchanger being arranged inside the second water tank for transmitting the heat generated by the heat source to said evaporation chamber, where the first and second water tanks are configured for being arranged in such a manner that the ratio in the level or capacity of water of the first and second tanks is of 1:20, and for maintaining the level once the evaporation of the water has started, by means of the supply of water from the first tank, which level is maintained by means of a plunger. The evaporation chamber comprises in the upper portion thereof, a means for distributing the heat and humidity generated in the evaporation chamber towards the fermentation chamber through a distribution system arranged in the lower portion of the evaporation chamber.Una fermentadora de alimentos la cual está conformada esencialmente por una cámara principal que comprende en su interior una cámara de evaporación, y una cámara de fermentación, en donde dicha cámara de fermentación comprende en su parte inferior un primer tanque de agua y un segundo tanque de agua conectado de manera fluida con el primer tanque de agua, dicho segundo tanque de agua el cual es alimentado por dicho primer tanque, está configurado para tener dimensiones menores que el primer tanque de agua un fuente emisora de calor alimentada por gas o electricidad dispuesta debajo del segundo tanque de agua para proporcionar calor al mismo al menos un intercambiador de calor dispuesto dent
