The120T/D Linya ng Produksyon ng Maize Flour is a high-capacity, fully integrated milling solution purpose-built for large-scale maize processing enterprises seeking industrial-grade output with consistent flour quality. Designed as aturnkey solution, this production line covers the entire value chain — from raw maize intake and cleaning, through tempering and degermination, to fine milling, sifting, and automatic packaging. With a daily processing capacity of 120 metric tons, it is ideally suited for commercial flour mills, industrial food ingredient plants, and large grain processing facilities that demand reliability, automation, and hygiene compliance throughout the production loop. The line is engineered to maximize endosperm extraction yield while minimizing power consumption and maintenance downtime, delivering a competitive ROI for mill operators.
Maize Flour Production Line Working Principle
The 120T/D maize flour production line operates on the principle ofgradual reduction milling combined with dry degermination technology. Raw maize kernels are first cleaned to remove impurities, then conditioned to optimize moisture content for efficient bran removal and endosperm release. The degerminated grits are progressively milled and sifted through multiple break and reduction passages, producing fine maize flour with controlled particle size distribution. The entire process is governed by a centralized PLC control system that monitors load, temperature, and flow rate in real time, ensuring consistent product quality with minimal human intervention.
Complete Workflow:
Raw Maize Intake & Storage → Cleaning (Sifter + Destoner + Magnet) → Tempering & Conditioning → Degermination → Maize Grits Milling (Roller Mills) → Plansifter Grading → Purification → Fine Flour Milling → Final Sifting → Automatic Packaging & Warehousing
1. （Cleaning Section）
Comprising a vibratory cleaner, destoner, magnetic separator, and suction aspiration system, this section removes all foreign materials — stones, metal, dust, broken kernels, and husks — with a cleaning efficiency exceeding 99%. It protects downstream equipment from damage and ensures flour purity from the very first stage.
2. （Tempering & Degerminator）
The horizontal dampener precisely adjusts kernel moisture to 16–18%, followed by a residence time of 20–40 minutes in a tempering bin for uniform hydration. The degerminator then mechanically separates the germ and bran from the endosperm using centrifugal impact force, minimizing germ breakage and maximizing grit yield.
3. （Roller Mill）
Each pair of counter-rotating rollers is configured with differential speeds and specialized roll corrugation for each milling passage. The gradual reduction approach — 4–5 break passages followed by 6–8 reduction passages — gently scrapes endosperm from bran without over-grinding, preserving starch integrity and reducing energy consumption.
4. （Plansifter）
Covering multiple sieve layers with graded mesh sizes from 12XX to 60XX, the plansifter separates ground material into bran, coarse grits, semolina, and flour fractions. Its balanced gyratory motion ensures high sieving efficiency and throughput without blinding.
5. （Purifier）
Positioned between break and reduction stages, the purifier uses controlled air currents and oscillating sieves to classify semolina particles by size and specific gravity, isolating pure endosperm particles from bran-contaminated fractions for higher flour brightness and lower ash content.
6. （Flour Blending & Packaging Station）
The final section includes an automatic flour blender for batch formulation, a high-precision electronic scale, and a valve-type bag packer (25 kg / 50 kg / 1 ton options) capable of 6–8 bags per minute, integrated with a sewing machine and conveyor for full-line automation.
Maize Flour Milling Plant Features
Fully Automated PLC Central Control System – Integrated touchscreen control panel for real-time monitoring of key parameters such as temperature, current, and output; supports one-button start/stop and self-diagnosis of faults.
Progressive Milling Process with Four Screening Stages + Eight Grinding Stages – Adopts the internationally mainstream “multi-stage grinding and screening” process route, effectively separating bran, germ, and endosperm to improve flour extraction rate.
All Stainless Steel Food-Grade Contact Components – All pipes, hoppers, and screens in contact with materials are made of 304 stainless steel, meeting international food safety standards, facilitating cleaning, and providing corrosion resistance.
Modular Frame Structure Design – The entire line utilizes a steel structure platform and modular splicing, shortening the installation cycle by 40% and facilitating subsequent capacity expansion or production line relocation.
Maize Milling Plant Advantages
Flour yield increased to 80–83% – Compared to traditional single-pass milling processes, flour yield is 5–8 percentage points higher, endosperm extraction is more thorough, and the economic value per ton of raw material is significantly improved.
Electricity consumption per ton of flour reduced by 15–20% – Optimized roller gap adjustment and variable frequency drive technology reduce unit energy consumption to 65–75 kWh/t, significantly reducing operating costs.
Flour ash content controllable at 0.45–0.65% – Through precise cleaning and grading processes, the finished flour has stable ash content, meeting the whiteness and purity requirements of high-grade food processing.
Labor costs reduced by over 60% – High degree of automation; the entire line requires only 3–4 operators to complete the entire process from feeding to packaging, solving the labor shortage problems of large factories.
Maize Flour Production Line Benefits
Rapid Payback Period (12–18 months) – The combination of high capacity, high flour yield, and low energy consumption results in substantial daily gross profit, typically recovering the equipment investment within 18 months.
Multi-functional Plant with Flexible Formula Switching – Grinding fineness and powder ratios can be quickly adjusted to meet different customer needs, supporting the production of various SKUs such as fine corn flour, coarse corn grits, and corn feed powder.
Comprehensive After-Sales and Warranty System – Provides a 12-month warranty on the entire machine, remote diagnostic support, and overseas installation guidance services, reducing the customer’s total cost of ownership (TCO) over the equipment’s lifecycle.
Compliant with International Export Standards – The equipment is certified by CE/SGS and other standards, ensuring smooth customs clearance and operation for exports to Africa, Southeast Asia, and the Middle East.
