摘要
本工艺为大豆热脱皮工艺。不仅大豆脱皮效果好,而且提高了大豆饼粕的质量。选用了高效振动筛、比重去石机、调质塔、快速干燥器、破碎机、皮仁分离器、轧胚机等先进的设备。调质塔不但能够提高大豆的温度,使大豆达到适宜于轧胚的温度70℃左右的温度,还降低了大豆的含水量,使含水量控制在10%左右。快速干燥器短的时间内使大豆的表面温度上升到90℃左右。由于只有豆皮的温度达到90℃,而豆仁的温度并不增加多少,这样就可以降低蛋白质的变性,有利于提高饼粕的质量。豆皮温度的提高有利于大豆破碎后皮仁的分离,且处理量大、能耗低。皮仁分离器是根据豆皮和豆仁悬浮速度的不同依靠风力将豆皮和豆仁分开,这样就可以得到含高蛋白的饼粕。液压轧胚机采用系统的压力来代替弹簧轧距调节装置的一种新型轧胚机。这种轧胚机是利用油缸中的液体压力来代替弹簧压力进行紧辊。它不仅大大提高了紧辊的压力,使轧出的料胚薄而给实,粉末度小,提高了胚片的质量,而且使生产能力得以成倍的增加。本次工艺在轧胚后增加了一个抽风装置,因为轧完胚后大量的水游离在胚片表面。增加这个装置大约可以除去1%水分,进一步降低胚片的含水量,有利于胚片的浸出。

Title A Research on Designing 2000t/d Pre- process Factory for Soybean
Abstract
The technology for soybean heat peeling process, not only dehulled soybeaneffective, but also enhancing the quality of soybean meal. Efficient use of the vibrating screen, the proportion Stoner, conditioning tower, rapid dryer, crusher, Pi-separator, Embryo rolling machine and other advanced equipment.Conditioning tower not only to raise the temperature of soybean, soybean appropriate to the temperature rolling embryo of about 70 ° C temperature, Soybean have also lowered the water content, water content control at about 10%. Rapid Dryer short period of time so that the surface temperature of soybean rose to 90 ℃. As only the hull of the temperature reaches 90 C, while the temperature of beans - no increase in the number This can reduce the protein denaturation, will be conducive to improving the quality of meals. This will be with the high-protein meal. . This machine is rolling embryo using the liquid fuel tank pressure to replace the spring bear pressure roller. It has not only greatly increased the pressure on the roll tight, rolling out the material to the embryo is thin, powder, it increases the quality of the embryo film, but also doubling the production capacity to increase. In this process rolling after the embryo of an increased ventilation devices, which rolled End embryos after a large amount of water free surface of the embryo. The device can be removed about 1% of water to further reduce the water content of tablets embryo, the embryo is conducive to the extraction unit.
