   Corn processing machinery Three ways to extract corn germ The technology of embryo extraction is the key technology in the processing of corn products. Do you know why to remove the germ? This is because corn germ contains rich oil and unsaturated fatty acids. If it is not separated and processed directly, it will have a bad impact on the quality of corn flour, corn flour and other products in the later stage. Better product quality can be achieved. Moreover, the separated corn germ can extract oil and improve the comprehensive utilization value of corn.

The technology of maize embryo extraction has made great progress. At present, there are three kinds of embryo extraction methods: dry method, wet method and semi wet method.

1. Dry method. Dry embryo extraction is a method of separating skin, embryo and endosperm by mechanical method without water regulation. The process is simple, low energy consumption, no pollution, but the efficiency of embryo extraction is low and the embryo contains more endosperm.

2. Wet method. Wet embryo extraction is a method of corn soaking, crushing and de embryo, and separating embryo and starch by liquid cyclone separator. The results showed that the efficiency of embryo extraction could reach 85% - 95%, and the moisture content of embryo was as high as 60%. It must be dried. The moisture content of the dried embryo was 2% - 4%, and the oil content was 44% - 50%. However, this way of corn processing machinery energy consumption, environmental pollution, high investment, high production costs, long investment recovery period.

3. Semi wet process. The principle of semi wet embryo extraction is to use the difference of moisture content and water absorption of corn germ and endosperm, as well as the difference of elasticity, toughness and crushing strength after water absorption, select suitable mechanical equipment to crush, peel and de embryo corn, and then use the different physical characteristics of embryo and endosperm to flatten the germ, while the endosperm is crushed, and then sift and sort out the germ To achieve the purpose of embryo extraction. The results showed that the efficiency of embryo extraction was more than 85%, energy consumption was low, no pollution, equipment investment was less, investment recovery period was short, production cost was low, but the embryo contained a certain amount of endosperm.
