Production line and factory setup overview
A maize dehulling, degerming, crushing, grading and polishing line for fine, medium and coarse grits with flour co-product.
Recommended lowest-entry line configuration Start at 300-500 kg/h with one cleaner, a combined dehulling and grits machine, aspiration, grading screens and semi-manual packing.

Production process and implementation sequence
- Maize intake and sampling
- Cleaning and magnetic protection
- Moisture adjustment
- Dehulling and degerming
- Controlled crushing
- Aspiration of light bran
- Grit sizing and optional polishing
- Weighing, sealing and lot coding
Products, capacity and market fit
- Local maize can be upgraded into multiple priced food fractions
- Small combined machines reduce initial building and conveying requirements
- Grits can serve household, institutional and snack-processing buyers
- Separated flour, germ and bran create additional saleable streams
- Coarse maize grits - Uniform large fraction with low bran specks - Porridge, food service and further processing
- Medium and fine maize grits - Buyer-defined graded fractions - Retail, snacks and institutional foods
- Maize flour, germ and bran - Separated and traceable co-products - Food, oil and approved feed users
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Air-screen maize cleaner | Removes dust, stones and foreign material | Screens selected for local maize |
| Magnet and moisture-control station | Protects equipment and prepares kernels for dehulling | Measured water addition only when trial requires |
| Combined dehuller and degerminator | Removes bran and germ with controlled endosperm loss | Adjustable pressure and aspiration |
| Grits crusher | Breaks clean endosperm into controlled particles | 300-500 kg/h entry reference |
| Air separator | Removes loose bran and light fractions | Dust-tight ducting and adjustable air |
| Grit grader and polisher | Separates saleable sizes and improves appearance | Interchangeable screens for launch grades |
| Product bins and scales | Keeps grades and co-products separate | Food-grade identified bins |
| Bag sealer or closer | Packs each grit grade | Semi-manual 1-25 kg launch range |
