Milling of maize is a crucial process in the agricultural industry as it helps in converting maize kernels into various maize products that are used for human consumption, animal feed, and other industrial purposes. The procedure of milling maize involves several steps that are aimed at separating the kernels from the rest of the maize plant, grinding the kernels into meal or flour, and then further processing it into different products. In this article, we will discuss the procedure of milling of maize in detail.

**Cleaning and Sorting of Maize Kernels**.

The first step in the milling of maize is cleaning and sorting the maize kernels. The maize kernels are harvested from the fields and are often mixed with other plant materials like stalks, leaves, and cob pieces. In this step, the maize kernels are separated from the other plant materials using various cleaning equipment like screens, air separators, and magnets. This ensures that only clean maize kernels are sent for the next step in the milling process.

**Conditioning and Moisture Adjustment**.

After the maize kernels are cleaned and sorted, they are conditioned and their moisture content is adjusted. Conditioning involves adding water to the maize kernels to soften them and make them easier to grind. The moisture content of the maize kernels is adjusted to the desired level using steam or water. This step helps in improving the milling efficiency and the quality of the final products.

**Grinding of Maize Kernels**.

Once the maize kernels are conditioned, they are sent to the grinding machine where they are ground into meal or flour. The grinding process involves crushing the maize kernels between two rough surfaces to break them down into smaller particles. The size of the particles can be adjusted depending on the final product required. The grinding machine used for milling maize can be a hammer mill, roller mill, or plate mill, depending on the desired end product.

**Sieving and Sifting of Maize Meal**.

After grinding the maize kernels into meal or flour, the next step is sieving and sifting the ground maize to remove any impurities or larger particles. This process helps in separating the fine maize meal from the coarse particles, husks, and bran. The sieved and sifted maize meal is then further processed into different products like maize flour, maize grits, and maize bran, depending on the requirements of the market.

**Packaging and Storage**.

The final step in the milling of maize is packaging and storage of the maize products. The processed maize products are packed into bags or containers and are labeled with relevant information like the date of production, expiry date, and nutritional information. The packaged maize products are then stored in warehouses or silos before they are shipped to the market for distribution and sale.

In conclusion, the procedure of milling of maize involves several important steps like cleaning, sorting, conditioning, grinding, sieving, and packaging. Each step is crucial in ensuring that the maize kernels are processed efficiently and the final products meet the quality standards of the market.
