Embodiment 1

[0035] The corn germ extracting processing technology of the present embodiment comprises the following steps:

[0036] (1) Screening: Screen high-quality corn in a vibrating sieve to remove dust and grains of sand larger and smaller than corn grains;

[0037] (2) Stone removal: remove the same heavy impurities as corn grains through the gravity-specific gravity stoner after the screened corn;

[0038] (3) Irrigation: the destoned corn is absorbed in the watering machine for 15 minutes to expand until the water content of the corn reaches 15%;

[0039] (4) degerming and slag breaking: the corn after the water treatment is degerminated and slag-breaking in the degerminator;

[0040] (5) Suction classification: the skin, powder, germ and endosperm obtained after the degerming process are subjected to suction separation through a suction separator and a classifier, and the germ and endosperm mixture is classified and sorted;

[0041] (6) Lifting: the sorted germ and endosperm m...

Embodiment 2

[0048] The corn germ extracting processing technology of the present embodiment comprises the following steps:

[0049] (1) Screening: Screen high-quality corn in a vibrating sieve to remove dust and grains of sand larger and smaller than corn grains;

[0050] (2) Stone removal: remove the same heavy impurities as corn grains through the gravity-specific gravity stoner after the screened corn;

[0051] (3) Irrigation: the destoned corn is absorbed in the water machine for 20 minutes to expand until the water content of the corn reaches 15.6%;

[0052] (4) degerming and slag breaking: the corn after the water treatment is degerminated and slag-breaking in the degerminator;

[0053] (5) Suction classification: the skin, powder, germ and endosperm obtained after the degerming process are subjected to suction separation through a suction separator and a classifier, and the germ and endosperm mixture is classified and sorted;

[0054] (6) Lifting: the sorted germ and endosperm mi...

Embodiment 3

[0061] The corn germ extracting processing technology of the present embodiment comprises the following steps:

[0062] (1) Screening: Screen high-quality corn in a vibrating sieve to remove dust and grains of sand larger and smaller than corn grains;

[0063] (2) Stone removal: remove the same heavy impurities as corn grains through the gravity-specific gravity stoner after the screened corn;

[0064] (3) Irrigation: the destoned corn is absorbed in the water machine for 25 minutes to expand until the water content of the corn reaches 16%;

[0065] (4) degerming and slag breaking: the corn after the water treatment is degerminated and slag-breaking in the degerminator;

[0066] (5) Suction classification: the skin, powder, germ and endosperm obtained after the degerming process are subjected to suction separation through a suction separator and a classifier, and the germ and endosperm mixture is classified and sorted;

[0067] (6) Lifting: the sorted germ and endosperm mixt...

Abstract

The invention discloses a corn germ extraction processing technology, and belongs to the technical field of corn processing. The corn germ extraction processing technology comprises the following steps: dampening; degerming and residue crushing; air suction separation: sifting and classification; separation of a germ and endosperm mixture; conveying of the germ and endosperm mixture into a color sorter by an elevator to sort germs and endosperm according to color difference sorting; and husking treatment on the sorted endosperm. According to the corn germ extraction processing technology, the corn is subjected to dampening treatment, so that the roots of the corn absorb water, the flexibility of the corn germ is improved, the binding force between the cortex and the germ body is weakened, the cortex of the root cap and the germ body can be completely removed by the degerming machine, then an air suction separator and a classifying screen are used for wind extraction and classifying screen classification, then the germ and endosperm mixture is conveyed into the color sorter through the elevator to be subjected to color difference sorting, so that the integrity of the germs is guaranteed, the germ extraction efficiency is improved, the integrity rate of the germs can reach 95%, the germ extraction efficiency can reach 99%, and the germ extraction quality and the germ extraction rate are far higher than those of an existing dry germ extraction method.

Description

technical field [0001] The invention relates to the technical field of corn processing, in particular to a process for extracting corn embryos. Background technique [0002] Corn is known as the "golden crop" and is one of the most important food crops in my country. Its 4 seeds are rich in nutrients and contain protein, fat, starch, sugar and vitamins and other nutrients. It can not only be used as grain, food and feed, but also has broad market prospects for its deep processing and comprehensive utilization. [0003] Corn kernels are composed of cortex, aleurone, endosperm, germ and root cap. The cortex covers the surface of the grain and consists of hard and compact cells (the epidermis) and a thin translucent membrane (the testa) that does not have a cellular structure. The epidermis is formed by oblong cells with thick walls and micropores, and has a certain degree of water absorption. Below the seed coat are the embryo and endosperm. The endosperm is a thick-walled...
