玉米皮-玉米胚芽压榨脱水

玉米皮-玉米胚芽压榨脱水

玉米湿磨是一种非常大的加工方式，玉米被加工成重要的产品，其中四种主要是玉米油、淀粉、果糖和动物饲料。

所用的方法是首先将收获的玉米粒浸泡在苛性钠溶液中。这样可以使玉米破碎，从而分离出胚芽。胚芽是玉米仁中含有玉米油的部分。大多数工厂将细菌运送到其他专门回收石油的工厂。分离细菌后，下一步是分离淀粉。玉米淀粉在另一个过程中转化为果糖。果糖是蔗糖（由甘蔗和甜菜生产）的替代品。

螺旋压力机在玉米湿磨工业中有两个重要的应用。其中之一是在淀粉被去除后对残余纤维进行脱水。这种纤维经干燥至低水分，然后制成颗粒作为动物饲料出售。为了尽量减少烘干机所需的燃料，在烘干机前面使用螺旋压力机，以尽可能地除去水分。压榨蛋糕的工业标准应在55%到58%之间。

第二种螺旋压榨在玉米湿磨中的应用是去除玉米胚芽中的水分。为了液化细菌中的脂肪，它通过排油器来回收油脂。然而，在将榨油机之前，必须将其脱水，这就是脱水螺旋压榨机非常有效的地方。尽管压榨后渣的含水量较低，为50%至55%，但压榨动作必须温和，以免挤压出油。

CORN HUSK - CORN GERM

Corn wet milling is an extremely large,where corn is processed into vital products, of which the four principal ones are corn oil, starch, f ructose, and animal feed.

The process used is to first steep the harvested corn kernels in a caustic solution. This allows the corn to be cracked so that the germ can be separated. The germ is the part of the kernel which contains corn oil. Most facilities ship their germ to yet other facilities which specialize in recovering the oil.

After separating the germ, the next step is to separate the starch. Corn starch is converted, in yet another process, into f ructose. F ructose is a substitute for sucrose (which is produced from sugar cane and sugar beets).

Screw presses have two important applications in the corn wet milling industry. One of these is in dewatering the residual fiber after the starch has been removed. This fiber is dried to low moisture content and then pelleted for sale as animal feed. To minimize the fuel required by the dryer, screw presses are used, ahead of the dryer, to remove as much water as possible. The industry standard for the output moisture content of the press cake should be in the range of 55% to 58%.

The second screw press application in corn wet milling is removing water from the corn germ. In order to liquefy the fat in the germ, it is run through an oil Expeller to recover the oil. However, before the germ can be pressed in an Oil Expeller, it must be dewatered.That is where the dewaterig screw presses are very efficient. Although the press cake moisture content comes out lower, 50% to 55%, the pressing action must be gentle in order not to squeeze out the oil.
