ABSTRACT
The maize kernels are screened, tempered with hot water/steam to loosen the germ and bran. Maize is generally processed to manufacture corn starch by wet milling method the world over. The viability of a maize processing plant depends upon the availability and uninterrupted supply of raw material to the unit. The possibility of obtaining it from adjoining states is also available. States like Bihar, Tamil Nadu, Karanataka, Andhra Pradesh and Punjab produce winter maize. The maize is generally packed in gunny bags in bulk. The most common mode of transportation is by lorries. The addition of steep water during the grinding generates a so-called maize mash. The mash is then carried over to a cyclone for germ separation. Afterwards the mash is fine-grinded in an impact mill for complete disruption of the maize kernels. Maize is usually processed by two distinct processes, namely wet milling and dry milling.
