挤压膨化大豆样品的机械采油(含外文出处)(中文3500字,英文5400字)
摘要：人们普遍认为，大豆是食用油和工业油的一个来源，其中脱油脂中的蛋白质也常作动物食品的来源。但是，最近几年，一些人认为使用豆粕作为蛋白质来源供人类食用，可以获得更多的利息。站在这个发展方向上为挤压膨化大豆提供了一个机会。集中于这项研究主要是：用三个不同类型的挤出机和不同的加工条件，最大限度地获得大豆油脂采收率。这些大豆样品随着时间的推移研究，最终在一个特别设计的试验中获得突破性进展。结果表明，超过90％的大豆油可以从大豆样品中施压挤出。通过研究，这些过程变量的影响包括：施加压力、热压温度和样品的高度。所产生的这些信息可以有效的解释在预处理大豆时过程变量和挤压设备所产生的影响。

Mechanical Oil Expression from Extruded Soybean Samples
ABSTRACT: Soybean is generally recognized as a source of edible and industrial oil, and the deoiled meal is seen as a source of protein in animal feed. In recent years, however, more interest has been directed toward using soy meal as a protein source for human consumption. Extrusion-expelling of soybean provides an opportunity in this direction. The main focus of this study was to maximize the oil recovery from extruded soybean processed using three different kinds of extruders and processing
conditions. These extruded samples were later pressed uniaxially in a specifically designed test-cell and the oil recovery was recorded over time. The effects of process variables, including applied pressure, pressing temperature and sample height, were investigated. Results indicated that over 90% of the available oil could be recovered from pressing of extruded soy samples. The information generated is likely to be useful in interpreting the effect of process variables and extruding equipment for pretreatment of soybean for subsequent mechanical oil expression.
