According to variety, aquatic feed raw materials, fine crushing changes require high degree and materials such as liquidity characteristic, production process design general use of the secondary crushing and secondary mixing to finish of powdery raw material processing; Powder materials by extrusion machine pressure molding, and then after drying, oil spraying and cooling process such as the screening to finish to feed into the finished product processing expanded packaging system. This process detailed tells the feed from the raw puffed accept to the finished product puffed granulating the whole process of the packing.Key words: puffing crushing pressing drying目 录摘 要…………………………………………………………………………..…I第1章 绪 论…………………………………………………………..……………11.1 膨化饲料简介…………………………………………………………………….11.2 膨化饲料加工工艺的内容……………………………………………….………11.3 膨化饲料的优点及缺点…………………………………………….……………2第2章 膨化饲料加工工工艺……..….…… ………………………………….…52.1 原料的接受、清理及粗粉碎……………………….…………………………52.2 物料的输送与搬运………………………………………………………………..62.3一次配料与混合…………………………………………………………………….….……72.4 二次粉碎…………………………………………………………………………..82.5 二次混合…………………………………………………………
