1《饲料工业》·圆园园7年第圆8卷第17期工艺设备干法膨化宠物饲料技术参数关系的研究单达聪季海峰王雅民摘要采用双螺杆膨化机干法工艺对宠物全价粉状饲料进行膨化并制粒，研究所得产品的容重与淀粉糊化度、硬度指标之间的关系，以及设备参数和配方特性对颗粒饲料容重的影响。结果表明：容重与淀粉糊化度、硬度密切相关；设备参数与配方特性均对产品容重有极显著影响；通过容重的测定估测其熟度和硬度具有可行性；可以通过调节喂料速度和膨化玉米比例控制产品容重。关键词参数关系；干法膨化；设备参数；配方特性；容重中图分类号S816.34Studyonthetechnologyparameterrelationshipforthepetfeedindry-wayextrusionShanDacong,JiHaifeng,WangYaminAbstractThecompleteandmealyfeedofthepetwasextrudedandpelletizedbythedry-wayextru鄄sionwithdouble-screwextruder,toresearchintotherelationshipbetweenthebulkweightandthegela鄄tinizationofstarch,thebulkweightandthehardnessofthepelletedfeed,andthesametimetostudytheeffectsoftheequipmentparameterandtheformulafeatureforthebulkweightofthepelletedfeed.Theresultshowedthattherewerehighcorrelationamongthebulkweight,thegelatinizationofstarchandthehardness.Theeffectsoftheequipmentparameterandtheformulafeatureishighlysignificantforthebulkweight.Itwaspermittedtoestimatthegelatinizationandthehardnessbythebulkweight,andtocontroltheproductsbulkweightbyadjustingthefeedingrateandtheproportionofextrudedmaize.Keywordsparameterrelationship曰dry-wayextrusion曰equipmentparameter曰formulafeature曰bulkweight双螺杆膨化机干法膨化工艺相对湿法而言省却了材料和方法1饲料调质器及其附属蒸汽锅炉和管道设备安全简饲料配方与膨化设备袁尧1.1单投资少适用范围广该工艺使饲料受热时间短而试验用饲料配方见表尧袁遥1遥对热敏营养成分破坏少是一种极具发展前景的全价袁表饲料配方及营养水平（）饲料膨化制粒生产工艺对全价宠物饲料膨化制粒可1豫遥项目一二三四五六七使淀粉糊化蛋白质变性消除和钝化抗营养因子灭尧袁尧配方组成玉米活有害微生物从而提高消化率改善饲料卫生状况54.749.542.035.752.750.349.9袁尧尧大米原5.27.418.95.35.25.2延长保质期检验全价颗粒型宠物饲料膨化加工程面粉遥原3.13.26.34.23.13.1花生仁粕度和效果的工艺指标有产品的熟度以淀粉糊化度表原原原9.45.85.25.2渊大豆粕23.06.35.3原原原原示容重和硬度测定熟度和硬度繁琐耗时而测定容小麦麸冤尧袁袁3.02.42.4原原原原膨化大豆重则简单易行使用该工艺加工产品时通过容重估测5.45.25.33.15.39.49.3遥袁鱼粉5.07.811.110.58.46.36.2其熟度和硬度通过调整设备技术参数和配方定量调猪肉粉袁2.55.25.35.25.35.25.2鸡肉粉控容重可为产品质量检验和控制提供极大便利本研1.08.48.45.210.510.510.4袁遥牛肉骨粉原2.62.62.6原2.12.1究目的是在双螺杆干法膨化工艺条件下验证通过颗粒全蛋粉原原3.2原原原原油脂容重定量估测熟度硬度指标的可行性以及明确设备2.00.8原原原原0.8尧曰预混料3.43.53.82.92.52.62.6参数和配方中各因素对容重影响的规律合计遥100100100100100100100营养水平蛋白质含量22.925.228.025.325.425.725.5无氮浸出物
