Purnia is one of India's top maize basins, yet grain leaves raw to mills in Bihar's neighbours and beyond. A maize processing unit producing corn grits, flour and flaking grade — sited on the Seemanchal rail hub — captures freight savings and the steady B2B demand from snack, brewery and poultry-feed buyers.

This unit dry-mills local maize into graded fractions: corn grits for the snack and brewing trade, corn flour for the food industry, and broken grade for poultry feed. It is anchored on the district's wider agri base around its Makhana (fox nut) heartland and, crucially, the Seemanchal commercial and rail hub that lets it move bulk grain and finished product cheaply toward Kolkata, Guwahati and the North-East. Purnia's structural problem is that it grows maize at scale but exports it unprocessed; this unit captures the milling margin the district currently gives away.
What it takes: a degerming-and-grading line, moisture control and aflatoxin testing (buyers reject on it), and reliable procurement against a sharply seasonal harvest, which makes working capital and silo storage the real constraint. The operator needs FSSAI and consistent particle-size specs to hold institutional contracts. Buyers are extruded-snack makers, breweries, cornflake brands, and large poultry integrators. A makhana grading-and-snack line can share the same packing floor and procurement team in a later phase.
