The present invention is to provide a fodder fermentation tank equipped with a warm water circulator, which heats water in a water tank to be circulated in the fodder fermentation tank so as to transfer hot heat, generated when fodder is fermented, everywhere uniformly within the fodder fermentation tank. In the fodder fermentation tank equipped with a warm water circulator, fodder stirring wings are vertically installed within a fodder stirring chamber arranged inside the fodder fermentation tank and are rotated by a decelerating motor a cylindrical water tank is installed outside the fodder fermentation tank and absorbs hot heat generated when fodder is fermented and the cylindrical water tank and a warm water adjustment tank forming the fodder fermentation tank, are connected to a warm water supply pipe and a warm water discharge pipe which include circulating pumps. According to the present invention, hot heat generated when fermented fodder is produced does not stay at one location, but heats water in the cylindrical water tank and circulates water through the warm water adjustment tank, thereby maintaining a suitable temperature required for fermentation to produce high-quality fodder inexpensively. In addition, hot heat generated when fodder is fermented will be used to heat water to be circulated into the cylindrical water tank making up the fodder fermentation tank and to ferment fodder, thereby greatly reducing energy consumption. Therefore, various advantages such as increasing the competitiveness of the livestock industry or the like are expected.COPYRIGHT KIPO 2016본 발명은 사료가 발효될 때 발생하는 고열이 사료발효탱크에 골고루 전달될 수 있도록 수조에 물을 데워서 사료발효탱크에 순환되도록 구성된 온수 순환장치가 구비된 사료발효탱크를 제공하려는 것이며, 사료발효탱크의 내부에 구비된 사료 교반실에 감속모터에 의해서 회전하는 사료 교반익이 수직으로 설치되고, 사료 교반실의 외부에는 사료가 발효될 때 발생하는 고열을 흡수할 수 있도록 원통형 수조가 구성되며, 상기 사료발효탱크를 구성하는 원통형 수조와 온수조절탱크가 순환펌프가 구비된 온수공급관과 온수배출관으로 연결되어 구성된 것이며, 본 발명에 의하면, 발효사료를 생산하는 과정에서 사료가 발효되면서 발생하는 고열이 한곳에 정체되지 않고 원통형 수조에 있는 물을 가열하고, 온수조절탱크를 경유하여 순환하기 때문에 발효에
