Located at the base of corn kernel, corn germ is taking up one-third of its volume, weight accounting for about 10-14 %. Corn kernels fat distribution in the vast majority of embryos, generally up to 34-47 %, and an average of 95.8 percent digestibility, high nutritional value. Since fat contains unsaturated fatty acids, easily oxidized deterioration, to safe custody of corn germ brought some difficulties. Therefore, embryos should be made in corn milling machine as far as possible, so that consumers cannot only get a higher value to increase oil resources, but also conducive to the safe custody of products, improve product quality goods.
In the study mentioned of dry corn germ milling machine, it is quite important to master the characteristics of the various parts of the corn, take reasonable processing methods, use high-efficiency equipment, on the one hand corn embryo as complete shedding, on the other hand the separation of a mixture of various substances to maximize yield and purity germ.
The main component of the endosperm has brittle cornstarch composition, low crushing strength. The main component is a fat germ, having elasticity and toughness, is not easy to be broken. For high- moisture corn, difference of corn germ processing is more significant, which provides a reliable basis for corn broken. Specific gravity, the speed difference between the suspension and the coefficient of friction for the embryo, using reasonable residue separation processes of corn germ, separation equipment selection and design provides reliable parameters.
Dry milling Corn germ making method
The adoption of dry corn milling machine method is generally depending on the product quality requirement and uses. The quality of corn flour in addition to required fineness and corn flour color, the fat content is also an important indicator during corn germ processing. Generally the limit of 1%, according to the product's use varies. Such as pasta, require not less than 1% fat content. For the wine industry, requires less than 1% fat content.
Oilmachineworld has recently designed new type dry milling corn germ making machine. There is no need of water addition during the whole process of corn germ making. The dry corn germ milling machine is quite reasonable processing method to get high quality corn germ with little breaks and residual. In addition, there is no water addition, thus no need of drying after corn germ removal. Dry corn germ milling is an efficient way to get high quality germ, save cost and electric consumption etc.
