Disclosed is an apparatus for manufacturing a feed additive for livestock and fish farming by using a grape byproduct and a propolis extract. According to the present invention, grape seeds, grape skins, and grape fruit stems, which are grape byproducts, are aged for a long period of time, and then the aged products are collected inside a hot-air drier and dried by hot air while discharging the hot air containing moisture generated at the time of drying. Therefore, dried materials of the grape seeds, the grape skins, and the grape fruit stems, which have a moisture content of 10%, are obtained. In addition, tartaric acid is mixed with the dried materials, followed by coarse pulverization, and then propolis extract powder is mixed with the coarse-pulverized grape byproducts mixed with the tartaric acid while the rotation rate of a mixing blade is controlled to achieve the optimum mixing state of each ingredient. In addition, the mixed materials are dried at low temperatures in a vacuum drier by maintaining a high degree of vacuum, thereby obtaining vacuum-dried materials having a moisture content of 5%. In addition, the vacuum-dried mixed materials are finely pulverized into 100-120 meshes in a fine pulverizing machine using a rotating blade rotating at high speed, and then the finely pulverized mixed materials are supported on a moving storage container below without flying. In addition, the high heat generated from the rotating blade is cooled to prevent the deformation of the mixed materials due to the heat at the time of fine pulverizing, and thus powder with high quality can be produced.본 발명에서는 포도부산물과 프로폴리스 추출물을 이용한 가축 및 양어용 사료첨가제 제조장치를 개시한다.본 발명에 따르면, 포도부산물인 포도종자(씨), 과피(껍질) 및 포도송이가지를 장시간 숙성시킨 다음, 이를 열풍 건조기 내부에 포집하여 열풍으로 건조하고, 건조시 발생 되는 수분이 포함된 열풍을 배출시킴으로써 함수율 10%의 포도종자(씨), 과피(껍질) 및 포도송이가지 건조물을 얻게 되었으며, 또한 건조물에 주석산을 배합하여 조분쇄하게 되고, 조분쇄된 주석산이 혼합된 포도부산물에, 프로폴리스 추출물 분말을 혼합날개부재로서 회전 속도를 조절하여, 원료별 최적의 혼합상태를 이루게 되었으며, 또한 혼합원료를 진공건조기에서 높은 진공도 유지로 저온에서의 건조가 가능하여 함수율 5%
