The 40T/D Maize Milling Plant For Small Corn Flour Factory is a fully automatic grain processing solution specially designed for small and medium-sized corn flour manufacturers, agricultural cooperatives, rural processing centers, and commercial flour mills. With a processing capacity of 40 tons per day, this complete maize milling plant integrates grain cleaning, conditioning, degermination, milling, sifting, flour grading, and automatic packaging into one efficient production line. It is engineered to produce premium-quality maize flour with high extraction rates, uniform particle size, excellent whiteness, and stable production performance while reducing labor requirements and operating costs.
Maize flour is one of the most widely consumed cereal products worldwide and is used to manufacture corn flour, cornmeal, breakfast cereals, tortillas, ugali, nshima, porridge, bakery products, snacks, and various food ingredients. Since maize kernels are composed of bran, germ, and starchy endosperm, efficient flour production depends on precise cleaning, proper moisture conditioning, effective degermination, and gradual roller milling. Our maize milling plant is specifically developed according to the physical characteristics of maize to maximize flour yield, preserve the quality of the endosperm, reduce bran contamination, and produce fine maize flour with excellent baking and cooking performance.
Working Principle
The maize milling plant utilizes advanced grain cleaning, moisture conditioning, degermination, roller milling, plansifting, flour purification, and automated packaging technologies to convert raw maize into high-quality maize flour. Each processing stage is carefully optimized to remove impurities, improve milling efficiency, increase flour extraction rates, minimize flour loss, and ensure consistent product quality. The PLC automatic control system coordinates every machine for stable, continuous, and energy-efficient operation.
Processing Flow
Raw Maize Feeding → Pre-cleaning → Destoning → Magnetic Separation → Moisture Conditioning → Degermination → Roller Milling → Plansifting → Flour Purification → Flour Blending → Automatic Packaging → Finished Product Storage
Main Equipment Description
• Raw Maize Feeding System
The feeding system transports raw maize smoothly into the production line through bucket elevators and conveying equipment, ensuring continuous material supply and reducing manual handling.
• Pre-cleaning Machine
The pre-cleaner removes dust, straw, broken cobs, leaves, husks, and other large impurities before milling, protecting downstream equipment and improving flour quality.
• Destoner
The destoner separates stones, sand, glass fragments, and other heavy contaminants from maize by utilizing differences in density and airflow, ensuring safer and cleaner processing.
• Magnetic Separator
The magnetic separator removes iron particles and metallic impurities that may enter during harvesting, transportation, or storage, effectively protecting the roller mills and extending equipment life.
• Moisture Conditioning System
The conditioning system accurately adjusts the moisture content of maize kernels before milling. Proper conditioning toughens the bran while softening the endosperm, resulting in higher flour extraction rates and lower bran contamination.
• Degerminator
The degerminator efficiently separates the germ and bran from the maize kernel before grinding. This process improves flour whiteness, extends shelf life by reducing oil content, and enhances flour quality.
• Roller Mill
The roller mill gradually grinds maize into fine flour through multiple milling passages. Precision rollers produce uniform particle size while maintaining high flour yield and minimizing starch damage.
• Plansifter
The plansifter separates flour according to particle size using multiple screening layers. Coarse materials are automatically returned for further milling, maximizing flour recovery and ensuring consistent fineness.
• Flour Purifier
The purifier removes residual bran particles using a combination of airflow and sieving technology, producing cleaner, brighter, and finer maize flour for premium food applications.
• Flour Blending System
The blending system mixes different flour streams according to customer specifications, ensuring stable flour quality, uniform texture, and consistent product performance.
• Automatic Packaging Machine
The automatic packaging system accurately weighs and packs finished maize flour into bags of different sizes, improving packaging efficiency while reducing labor intensity.
