The present invention relates to a liquefied fertilizer producing device for producing a liquefied fertilizer by fermenting treatment water separated from livestock excrement. The liquefied fertilizer producing device comprises: a reaction tank having an accommodation space formed therein to accommodate the treatment water, and capable of being selectively sealed; a circulation unit connected with the reaction tank, supplying the treatment water accommodated in an upper current layer to a lower side of the accommodation space, and circulating the treatment water;an air supply unit for supplying oxygen or air to the treatment water circulating by the circulation unit, and promoting the fermentation of the treatment water; and a defoaming unit including a suctioning pipe for suctioning the treatment water to one side in the accommodating space, and a spraying means disposed in an upper side of the reaction tank to be connected with the other side of the suctioning pipe and to have a plurality of spraying holes spaced apart from each other, wherein the spraying means sprays the treatment water suctioned through the suctioning pipe to a lower side thereof in a non-pressing way. The defoaming unit suctions the treatment water accommodated in the reaction tank, sprays the treatment water from an upper side to a lower side thereof, and removes bubbles generated from the treatment water. |
