Innovative Technology for Semi-Dry Extraction of Corn Germ and Bran, and Production of Low-Fat Corn Flour

Section One

Detoxify and reduce the processing stage.

After cleaning and separation, the equipment removes organic impurities from the raw grains as well as various mycotoxins adhering to the surface of the grains, thereby ensuring food safety.
Detoxify and reduce the processing stage.

Section Two

Homogeneous De-embryonation Screening Section

Using the double-cone rubbing and embryo-removal screening equipment, corn kernels are rubbed into four-, six-, or eight-lobed segments, ensuring that the germ remains undamaged and its integrity is fully preserved.

01

Multi-stage purification with a high impurity removal rate.

The four-stage integrated system—comprising a vibrating grain-cleaning screen, a specific-gravity stone-removal machine, a magnetic soil-removal machine, and an optoelectronic color-sorting machine—comprehensively removes various impurities from grains based on four key parameters: particle size, specific gravity, magnetic properties, and color. The overall impurity removal rate reaches ≥99.5%, and the purity of the finished product exceeds 99.8%, fully meeting the stringent raw-material requirements of high-end food processing.

02

Dedicated equipment empowers condition.

The HuaYu Wantong Flexible Polishing Machine employs flexible grinding technology that not only removes impurities and enhances brightness but also ensures the integrity of the beans, preventing damage. Paired with an optoelectronic color-sorting machine, it precisely controls color, resulting in finished bean products with uniform color and smooth surfaces—significantly superior in appearance to raw materials processed by conventional cleaning equipment.

03

Carefully selected, with nothing missed.

Equipped with high-speed recognition and jet-air sorting technology, the photoelectric color sorter can detect even tiny impurities with particle sizes ≥0.5mm as well as defective beans that exhibit minimal color differences, thereby addressing the issues of low efficiency and high omission rates associated with traditional manual sorting and achieving effective purification.

04

Automated effective operation

The entire process—from raw material input to finished-product storage—is highly automated, with equipment operating in seamless coordination to minimize human intervention. The daily processing capacity can range from 50 to 500 tons, striking a balance between large-scale production and operational convenience, while reducing human error and labor costs.

05

Highly adaptable and widely versatile

It can flexibly accommodate the processing of various types and particle sizes of beans, including soybeans, mung beans, chickpeas, kidney beans, and more, without the need for frequent replacement of equipment components, thus meeting the production demands of multiple bean varieties.

06

Green and environmentally friendly, zero pollution

The entire process employs physical processing methods, with no chemical additives and no additional water added, thereby avoiding wastewater pollution. The dust collection systems integrated into the polishing machine and grain-cleaning sieve efficiently manage dust, reducing workshop contamination and meeting green production standards.

I. Core Operational Logic

This production line centers on a progressive process of “Physical Separation + Precision Purification.” Leveraging coordinated equipment operations, it capitalizes on the inherent differences between legume raw materials and various impurities in particle size, specific gravity, magnetic properties, adhesion, and color. Through the sequential steps of “Preliminary Impurity Removal - Deep Purification - Appearance Optimization,” it achieves purification and quality enhancement of legume raw materials. The entire process involves no chemical additives or additional water, relying primarily on physical methods. This approach safeguards the natural quality of legumes while ensuring product integrity. - Precise Grading - Finished Product Protection." The entire process involves no chemical additives or additional water, relying primarily on physical methods. This approach preserves the natural quality and integrity of the beans while effectively removing impurities, yielding high-purity, uniformly colored, and storage-stable premium bean raw materials.

II. Core Equipment Synergy Logic

1. Production line equipment achieves effective coordination through “parameter adaptation + closed-loop process”:

2. Vibrating grain cleaners supply uniformly sized raw materials to downstream equipment, preventing large and small impurities from affecting the air suspension precision of gravity stone removers and the magnetic field adhesion accuracy of magnetic soil removers;

3. The gravity stone remover and magnetic soil remover progressively eliminate heavy impurities and metal contaminants, reducing grinding load on Huayu Wantong's flexible polishing machine and preventing abrasion damage to polishing rollers from hard impurities.

4. The polishing machine enhances surface purity by minimizing color variation and impurity interference, boosting the color recognition accuracy of the photoelectric color sorter by over 30% and reducing misjudgment rates.

5. An automated control system coordinates all equipment parameters (e.g., vibration frequency, airflow velocity, polishing speed, color sorting thresholds) throughout the process. This achieves seamless integration from “raw material input → purification → optimization → selection → storage,” ensuring consistent purity and appearance across every batch while delivering robust production stability.
