What is involved in corn milling?
corn, also known as corn in many countries, is an important crop of grain made worldwide for use in a wide range of food and as food for livestock. After harvesting, the corn must be subjected to milling to improve the products. The two main corn milling processes are wet milling and dry grinding. Wet milling is used to produce food ingredients and animal feed, while dry milling is primarily used to produce ethanol, widely used alcohol compounds that have application as biofuels.
The only corn core consists of several useful components. Embryo or plant embryo contains oil. The mask part of the core surrounding the germ, called endosperm, contains starch; carbohydrate or sugar; And gluten, protein. When grinding industrial corn, the aim is to extract these core components so that they can be used to create different products. Milk and sulfur dioxide soften the nuclei and release starch. After this step is toUkurice grounded. The baker is removed by lowering ground maize and water through the separator, causing the oil key to float on the surface. This part of the core can be used to produce corn oil; food products; and germ food, livestock feed.
After removing the germs, the fiber, which is also used in animal feed, is proven from the remaining starch and gluten. Centrifugees spin starch and gluten at high speeds, causing to separate by density. Gluten is added to the fiber for use in sources and starch is used in human food, textile, paper and many other applications. Starch consists of most products produced by wet corn milling, followed by gluten and corn oil.
dry milling of corn includes fermentation, a biochemical process in which ethanol is made from sugars in corn cores. In the first step of this process JE corn grinded into great food. Starch in this meal must then undergo liquefaction. Water and enzyme are added to stimulate the hydrolytic reaction that breaks down the starch molecules on long sugar chains.
Furthermore, starch is heated to destroy unwanted bacteria and divide into basic sugars using another enzyme. Yeast is added to sugar metabolization. Through the metabolic activity of yeast, sugar is converted into ethanol and carbon dioxide. This process is known as fermentation. The main product of dry milling, ethanol, has a number of uses as an industrial chemical and fuel, while the co -product of the process can be used as a further addition of feed for livestock.
