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

Peeling—Synergistic Enhancement of Skin Exfoliation

The Huayu Wantong bean splitting and peeling machine is precisely matched with the peeling machine. The splitting stage weakens the bond between the bean skin and the bean kernel, boosting the peeling rate to over 98%. Compared to traditional direct peeling methods, the residual bean skin rate is reduced by 80%, and the damage rate of the bean kernels is no more than 3%, striking a balance between efficiency and quality.

02

Multi-stage purification with high purity

The five-stage integrated system—comprising a grain-cleaning sieve, stone-removal machine, magnetic separator, dust-removal unit, and color sorter—effectively removes all types of impurities, from coarse and heavy contaminants and metallic debris to bean skins, damaged beans, and fine powders. The resulting pure soybean kernels achieve a purity level of ≥99.5%, meeting the stringent raw-material requirements of high-end food processing.

03

The dedicated equipment has strong adaptability.

The Huayu Wantong series of pod-breaking and hulling machines are designed specifically for legume characteristics, offering flexible compatibility with various types and particle sizes of beans, including soybeans, mung beans, chickpeas, and kidney beans. These machines are highly versatile and do not require frequent replacement of equipment components.

04

Bean kernel quality is stable and controllable.

The entire process employs flexible processing technology (gentle pod cracking and soft skin removal), which prevents excessive damage to the soybean kernels or loss of nutrients. As a result, the finished soybean kernels maintain high integrity and natural color, and graded screening ensures uniform specifications, making them suitable for a wide range of downstream applications.

05

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 reach 50 to 200 tons, striking a balance between large-scale production and operational convenience, while reducing human error and labor costs.

06

High raw material utilization rate

There are no material-waste stages throughout the entire process, and both small bean kernels and fine powder can be effectively recycled. Combined with Huayu Wantong’s low-damage processing technology, the comprehensive utilization rate of raw materials reaches over 98%, significantly enhancing production economic benefits.

I. Core Operational Logic

This production line centers on “physical separation + flexible processing,” leveraging coordinated equipment to exploit inherent differences in particle size, specific gravity, magnetic properties, adhesion, and color among soybean components (bean skins, kernels) and impurities. Through a progressive process of "multi-stage purification - shell-breaking assistance - Precise Dehulling - Deep Purification - Graded Storage" progressive process to achieve effective separation of bean skins and kernels. The key innovation lies in the synergistic “fracturing + hulling” process. Gentle fracturing weakens the bond between hull and kernel, followed by precise flexible hulling. This chemical-free, water-free method preserves kernel integrity (crush rate ≤3%) while achieving high hulling purity (≥98%), yielding consistently high-quality, pure hulled kernels.

II. Core Equipment Synergy Logic

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

1. In the pre-treatment stage, the grain cleaner, stone remover, and magnetic separator operate sequentially to eliminate impurities based on particle size, specific gravity, and magnetic properties. This provides clean, uniform raw material for the splitting machine and hulling machine, preventing impurities from affecting splitting efficiency and hulling purity.

2. Huayu Wantong's kernel splitter and hulling machine feature precise parameter coordination (linked kernel size and hulling speed). After the splitter weakens seed bonds, the hulling machine achieves effective removal at lower friction intensity, minimizing kernel damage;

3. The peeling machine, powder remover, and color sorter work in tandem. Bean skins and fine powder are immediately removed after peeling, reducing interference from impurities on the color sorter's recognition accuracy and enhancing purification efficiency.

4. Grading equipment interfaces with finished product silos for directed storage of size-sorted kernels. Small fragments and fine powder are recycled, forming a “processing-grading-reuse” closed loop with over 98% raw material utilization.

5. An automated control system centrally manages operational parameters (e.g., vibration frequency, airflow velocity, rotational speed gaps) across all equipment. This ensures consistent hulling rates, purity, and kernel integrity for every batch, delivering exceptional production stability.
