PURPOSE: An automatic feed steaming apparatus is provided to easily input or discharge feed by having a top opening/closing part where feed is vertically provided. CONSTITUTION: A combination steamer(110) is equipped with a top opening/closing part(111) where feed is vertically provided. A mixer is equipped in the combination steamer and stirs and blends input feed. Spiral rotary wings are adhered to the outer periphery of a driving means which drives up and down movement and rotary motion of the mixer. Multiple cutters are adhered to the outside of the spiral rotary wings and cut the input feed. A steamer steams the feed with high temperature steam which is supplied from a steam generating apparatus. A rotary motor rotates the combination steamer to the correct area. A discharging means(114) discharges the feed stirred and blended in the combination steamer and steamed by the steamer to the outside. The top opening/closing part is hinged to the combination steamer and opens and closes. The steamer comprises the steam ejector for steaming the feed in the combination steamer with supplied vapor. The combination steamer can be moved by being mounted on a transfer dolly. A control panel is equipped outside of the combination steamer and controls on/off operations of all driving apparatuses. A display panel is equipped outside of the combination steamer and indicates the internal condition of the combination steamer.본 발명은 사료 배합장치에 있어서, 직립형으로 사료가 투입되는 상부 개폐부를 구비한 배합 찜통； 상기 배합 찜통에 구비되며, 투입된 사료를 교반 배합하기 위한 교반기； 상기 교반기의 외주면에 부착되며, 상기 교반기의 상하이동과 회전운동을 구동시키는 구동수단의 외주면에 부착되는 나선형 회전날개； 상기 나선형 회전날개의 외측에 부착되어 투입된 사료를 절단하기 위한 다수개의 절단기； 및 상기 배합 찜통에 구비되며, 증기발생장치로부터 공급되는 고온 증기로 사료를 찌는 찜기；를 포함하는 것을 특징으로 하는 자동 사료 찜장치를 제공한다.
