- 花生冷榨工藝設(shè)計(jì)設(shè)計(jì)說明書要：冷榨制油是指油料在入榨前不經(jīng)蒸炒等高溫處理，入榨溫度為常溫或略高于常溫及壓榨過程料溫較低的榨油方法。應(yīng)用花生直接冷榨制油技術(shù)，減少了精煉污水的排放有利于保護(hù)環(huán)境，同時(shí)，制得的花生油除具有普通制油工藝的一般特征外，更在于提高了油脂品質(zhì)，避免了高溫加工油脂產(chǎn)生反式脂肪酸、油脂聚合體等有害物質(zhì)，保留了油中的活性物質(zhì)，同樣冷榨餅的營養(yǎng)價(jià)值也有很大提高，蛋白質(zhì)變性少更多活性物質(zhì)得以保存，提高了餅的開發(fā)價(jià)值。介紹了花生直接冷榨的工藝、各個(gè)過程的操作方法及注意事項(xiàng)，對(duì)花生冷榨直接制油工藝進(jìn)行了設(shè)計(jì)，并進(jìn)行了物料衡算和熱量衡算；對(duì)花生冷榨制油所需要的設(shè)備進(jìn)行了選擇并核算了所需臺(tái)數(shù)；用CAD繪制了制油的工藝流程圖以及車間布置圖，完成對(duì)花生冷榨制油的工藝設(shè)計(jì)。

Abstract: Cold pressing for plant oil is a press way that oilseeds don’t need to be heated such as steam cooking, the pressing temperature is normal or a bit higher than that, and the material temperature is lower during the process of pressing. By the technology of cold pressing for peanut oil directly, the discharge of wastewater produced by refining could be reduced and it would be helpful to the protection of environment. Meanwhile, the peanut oil produce dose not just maintain the characteristic of normal way of producing, but also retain active components without harmful materials such as trans-fatty acid and oil polymer produced when the oil was dealed with under high temperature. So the quality of cold pressing oil and the developing venue of cold pressing cake were higher. The technology, each part of operating method and advertent problems of direct cold press of peanut were introduced; the technology was designed and the material balance and heat balance were made; the equipments for cold pressing of peanuts were chosen and the number needed is decided; the process flow diagram and department arrangement diagram were drawn by CAD.
Key words: peanut; cold pressing; cold pressing oil; cold pressing cake.
