This large-scale maize milling plant is widely adopted in Africa, Latin America, and Southeast Asia, where governments, grain reserve authorities, or leading food companies establish centralized plants to secure food supply. It is particularly suitable for regions with high maize consumption, where large-scale logistics and distribution systems support the continuous demand.
500TPD Maize Milling Plant Process Flow
500TPD Maize Milling Project process is based on a dry milling method, which guarantees consistent flour quality and minimal energy consumption.
1、Cleaning and Destoning
Raw maize is pre-cleaned using high-capacity vibrating cleaners and destoners to remove dust, stones, and impurities. The cleaning section is equipped with magnetic separators to eliminate metallic contaminants.
2、Dehulling and Degermination
Advanced dehullers and degerminators are applied to separate bran and germ efficiently. This step ensures flour whiteness and longer shelf life while securing high extraction rates.
3、Conditioning and Milling
Moisture conditioning improves kernel flexibility. High-strength roller mills then crush and grind the maize, achieving uniform granulation while preserving nutritional value.
4、Sifting and Grading
Large-capacity plansifters classify flour and grits into different mesh sizes. At this stage, by-products such as bran and germ are collected separately for feed or oil processing.
5、Blending, Fortification, and Packaging
Final flour is blended according to customer specifications and fortified with micronutrients if required by local food regulations. Fully automated packing lines allow both bulk and retail packaging.
Types of Maize Flour Produced by Mesh Size
60–80 mesh fine maize flour – for bread, biscuits, noodles, and instant foods.
40–60 mesh medium maize flour – for porridge, chapati, tortillas, and household cooking.
20–40 mesh coarse grits – for beer brewing, snack food, and breakfast cereals.
Bran and germ by-products – for animal feed or oil extraction.
