Corn Processing Training Programme

Corn Processing Training Programme- The Corn Processing industries and corn processing plants produce much important food, industrial and chemical products from corn grain, and in the process produce many important by-products that have increased nutritional and economic impact on our food supply. There are two distinct techniques that are used to process corn:  wet milling and dry milling. Wet milling processors or corn wet milling companies generate pure corn starch, which has many food and industrial uses.  In addition, corn oil, corn products and many other by-products are produced. Dry Milling processors produce starch for ethanol and other products, while valuable by-products for use in animal feeds.


The first step of processing corn germ from wet milling or dry milling is to properly prepare the seed for oil removal. There are also corn wet milling process flow chart available. The seed is delivered clean; additional cleaning with a magnet and screener may be done to remove any impurities or fines. For dry-milled germ, the seed is conditioned, flaked and sent to solvent extraction. For wet-milled germ, the seed is conditioned, flaked and cooked, then pressed prior to solvent extraction. For smaller capacities, the germ can be fully pressed instead of solvent extracted.


The wet-milled germ seed is mechanically pressed (pre-pressed) to extract approximately half to three-quarters of the available oil so that the solvent extraction can be run more efficiently. This is typical for seeds containing more than 20% oil. The solvent extraction process uses hexane or other solvents to wash the corn oil from the prepared flakes or press cake. The design of the equipment varies so that the Crown can optimize the amount of solvent and bed depth needed to efficiently wash the flakes, the contact time of the solvent and flakes, and the power and utilities needed to run the equipment. Corn germ is processed with the Model III Extractor. And the next processes are Desolventizing, Oil refining, and processing, Biodiesel, Oleochemicals.
