The present invention relates to a feed mixing apparatus. A plurality of separation walls are formed between an upper plate and a lower plate. An agitator, which discharges water at predetermined pressure in the direction of the outside and is rotated at the same time, is joined to a rotation axis and is located in an agitation container. A driving motor for rotating the rotation axis is installed on an upper side of the agitation container. Since a discharge pump is installed on a discharge pipe of the agitation container and the driving motor is operated, the agitator is rotated in forward and backward directions by the rotation axis joined to the driving motor and, discharges water at a predetermined pressure and feed in the direction of the outside at the same time, and generates centrifugal force around the same. Accordingly, the feed and water, provided to the inside the agitation container, are rotated around the agitator. The feed and water are discharged in the inner circumferential direction of the agitation container by discharge pressure of the water and the feed discharged in the direction of the outside of the agitator, and at the same time, they are uniformly mixed. According to the present invention, as the water and feed spread in a radial direction and are mixed in the inner circumferential direction of the agitation container, the mixing ratio is increased. As a material in a gel phase is discharged in the direction of the outside of the agitator and generates centrifugal force at the same time, the material is rotated along the inner circumferential side of the agitation container and is uniformly mixed. In particular, the material in a gel phase is discharged in the direction of the outside of the agitator by the rotational force of the agitator and, thus, does not adhere to the inside of the agitator. Accordingly, the rotational force of the agitator is maintained, and at the same time, overload on the driving motor is prevented. Consequently,
