15–25 Tons Per Hour Complete Rice Milling Unit

Product Introduction

This complete rice milling unit is a modular, scalable grain processing system tailored for medium-to-large grain processing enterprises, grain depots, and agricultural industrial parks. Covering the entire process from raw paddy cleaning, stone removal, hulling, paddy-brown rice separation, milling, polishing to grading and packaging, it supports flexible capacity adjustment between 15 t/h and 25 t/h to match different production scales. The unit integrates intelligent control technology, realizing automated operation and real-time monitoring of key indicators such as broken rice rate and whiteness, which not only improves production efficiency but also ensures the stable quality of finished rice.

Core Advantages

1. Flexible Capacity & Strong Adaptability

The unit adopts a modular design, allowing free switching between 15 t/h and 25 t/h production capacity by adjusting the number of grinding rollers and the speed of the conveyor system. It is compatible with various paddy varieties including indica rice, japonica rice and glutinous rice, and can produce different grades of rice such as standard grade rice, high-grade polished rice and germ rice by replacing screen meshes and adjusting grinding parameters.

2. High Processing Quality & Low Loss Rate

Equipped with high-carbon steel alloy nitrided grinding rollers and multi-layer precise classification screens, the unit achieves a hulling rate of ≥ 99.8% and a broken rice rate of ≤ 1.0%. The rice bran separation system with adjustable air volume ensures that the rice bran contains rice rate ≤ 0.5%, greatly reducing grain loss during processing. The finished rice has uniform whiteness, smooth surface and good taste, meeting national first-class rice standards.

3. Intelligent Operation & Low Labor Cost

The whole unit is controlled by an intelligent PLC system, supporting functions such as remote parameter setting, fault alarm and automatic shutdown protection. One person can complete the operation of the entire production line, which saves 60% of labor costs compared with traditional semi-automatic equipment. The system can automatically record production data, facilitating enterprise production management and traceability.

4. Stable Performance & Easy Maintenance

The key components such as gearbox and motor are made of well-known brand parts, with a transmission efficiency of ≥ 98% and stable operation for 24 hours without failure. The modular structure enables quick disassembly and replacement of wearing parts such as grinding rollers and screens, reducing maintenance time by 50% and lowering daily operation and maintenance costs.

5. Energy Saving & Environmental Protection

Adopting variable frequency speed regulation technology, the unit can adjust power consumption according to actual production capacity, saving 15–20% of energy compared with fixed-speed equipment. The closed dust removal and rice bran collection system effectively reduces dust emission in the workshop, and the collected rice bran can be directly used as feed raw materials, realizing resource recycling.
