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.

Section Three

Optoelectronic Technology – Grading and Embryo Extraction Section

AI-optoelectronic technology equipment is used to effectively separate pure germ and pure endosperm.

Section Four

Tippy Selected Work Section

Equipped with adjustable micro-negative-pressure suspension technology, this system achieves a gentle separation of the skin from the endosperm granules based on their differing densities.

Section Five

Light R&D Powder Section

The graded endosperm is processed through advanced light milling and fine grinding technologies to produce yellow, low-fat corn flour. All physicochemical indicators meet the requirements for application in sugar fermentation processes.

01

Efficient and low-loss embryo removal

The “steam conditioning + flexible embryo removal” combined process achieves an embryo removal rate of ≥92% and an integrity rate of ≥96%, significantly surpassing the results obtained with conventional equipment that relies on hard-contact embryo removal.

02

High purification accuracy

Multiple purification processes work in synergy to achieve a germ purity of ≥98.5%, free from impurities and foreign-colored grains, with consistently stable quality.

03

High degree of automation

From impurity removal and embryo separation to purification and metering, the entire process is driven by interconnected equipment, with intelligent control of key parameters. A single production line requires only 2-3 operators, and its daily processing capacity can reach 100-500 tons.

04

Strong device compatibility

The core equipment—intelligent degerming machine and flexible embryo-cleaning machine—supports parameter adjustment, enabling them to meet the embryo-extraction needs of different corn varieties and offering high versatility.

05

Production safety and controllability

Iron removal via magnetic separator + multi-stage purification—preventing equipment damage and product contamination, and complying with food production safety standards.

06

End-to-end low-loss quality control

From the flexible kneading of the intelligent degerminator, the gentle pressing of the embryo-pressing machine, to the soft treatment provided by the flexible embryo-scrubbing machine—entirely avoiding hard contact throughout the process—thus enhancing the integrity rate of the germ.

I. Core Operational Logic

This production line centers on a “multi-stage purification and impurity removal + steam conditioning and softening + gentle degerming + graded purification” process. Addressing corn's characteristics of “tight adhesion between germ and endosperm requiring low-loss separation.” By leveraging differences in specific gravity, particle size, and color among components (germ, endosperm, seed coat), it employs end-to-end physical processing to achieve “complete impurity removal, intact germ separation, and precise purity control.” Strict control of key parameters throughout ensures ≥92% germ stripping rate, ≥98.5% pure germ purity, and ≥97% raw material utilization rate.

II. Core Equipment Synergy Logic

1. Purification - Grain Conditioning - Germ Removal Synergy: First remove impurities and stabilize material, then soften the grain to lay the foundation for low-loss germ removal.

2. Germ Removal - Closed-Loop Re-removal: Material not fully degerminated is recycled to ensure thorough removal.

3. Progressive Purification Synergy: Multi-stage impurity reduction gradually elevates purity from 95% to 98.5%.

4. Low-Loss Throughout: Flexible processing avoids hard contact, achieving ≥96% germ integrity rate.
