玉米皮-玉米胚芽壓榨脫水

玉米皮-玉米胚芽壓榨脫水

玉米濕磨是一種非常大的加工方式，玉米被加工成重要的產(chǎn)品，其中四種主要是玉米油、淀粉、果糖和動物飼料。

所用的方法是首先將收獲的玉米粒浸泡在苛性鈉溶液中。這樣可以使玉米破碎，從而分離出胚芽。胚芽是玉米仁中含有玉米油的部分。大多數(shù)工廠將細(xì)菌運送到其他專門回收石油的工廠。分離細(xì)菌后，下一步是分離淀粉。玉米淀粉在另一個過程中轉(zhuǎn)化為果糖。果糖是蔗糖（由甘蔗和甜菜生產(chǎn)）的替代品。

螺旋壓力機在玉米濕磨工業(yè)中有兩個重要的應(yīng)用。其中之一是在淀粉被去除后對殘余纖維進(jìn)行脫水。這種纖維經(jīng)干燥至低水分，然后制成顆粒作為動物飼料出售。為了盡量減少烘干機所需的燃料，在烘干機前面使用螺旋壓力機，以盡可能地除去水分。壓榨蛋糕的工業(yè)標(biāo)準(zhǔn)應(yīng)在55%到58%之間。

第二種螺旋壓榨在玉米濕磨中的應(yīng)用是去除玉米胚芽中的水分。為了液化細(xì)菌中的脂肪，它通過排油器來回收油脂。然而，在將榨油機之前，必須將其脫水，這就是脫水螺旋壓榨機非常有效的地方。盡管壓榨后渣的含水量較低，為50%至55%，但壓榨動作必須溫和，以免擠壓出油。

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.
