Application of corn processing equipment in making grits and corn germ extraction

　　Corn is a kind of food crop that is often encountered in daily life. Since it can be made into grits and powder, it can be used to make porridge, noodles, steamed buns, etc., so it has good uses. We know that corn processing equipment is required to process corn. Let’s learn about the application of corn processing equipment in making grits and embryo extraction.

　　Based on actual life analysis, after the embryo extraction treatment of corn processing machinery, using corn as raw material, in the process of producing corn grits, corn starch or corn starch sugar, about 8% to 12% of corn germ can be recovered. After collection, it can Used to prepare corn germ oil and corn germ protein.

　　When extracting embryos, in order to make the embryos in the corn fall off completely and improve the germ acquisition rate and purity, personnel pay attention to using qualified quality machinery and use reasonable processing methods. There are two main methods commonly used at present, namely dry method and wet method. The former is widely used in the flour milling industry, and the latter is suitable for starch processing and production.

　　In corn processing equipment, corn grits extraction and embryo extraction are an important process. In modern corn processing equipment, corn grits extraction and embryo extraction are carried out simultaneously, that is, grits extraction and embryo selection. Generally, the process flow of corn processing complete sets of corn processing equipment is mainly divided into two types: grits and embryo lifting by suction-type specific gravity embryo lifting machine and grits and embryo lifting by gravity embryo lifting machine.

　　1. The process of lifting the grits and embryos using a suction-type specific gravity embryo lifting machine uses two suction-type specific gravity embryo lifting machines in series to lift the grits and embryos. The materials after the grits are broken are graded with a flat sieve, and the 4-5W sieves are separated, and the 7-8W sieves are put into the embryo lifting machine. After the corn residue extracted by the two embryo lifting machines is shaped and polished, it is graded by screening and separated. After the large and medium grits are discharged, the slag and embryo mixture separated by the second embryo extraction machine enters the embryo pressing and grinding process to extract the embryos. In corn processing equipment, this process can extract corn residue with low fat content, but it cannot directly extract corn embryos.

　　2. The grits and embryos are lifted and broken by the gravity embryo lifting machine. The degermed materials are graded according to particle size using a flat screen to separate large and medium residues. After being peeled by the air selector respectively, they enter two gravity embryo lifting machines. The machine selects large and medium slag and embryos; the large and medium slag is polished and shaped with a sand roller rice machine to become large and medium grits. The separated slag and embryo mixed materials are pressed into embryos and ground into powder. Generally, the embryos are further extracted after the second pressing and second screening. This process can directly extract corn embryos with higher purity.

　　The above is the role of corn processing machinery in embryo extraction and the relevant introduction to the embryo extraction process. I hope it can be helpful to everyone!
