Large-scale production scenarios—including large grain and oil processing plants, major grain and oil markets, food deep-processing enterprises, feed production companies, and germ oil processing enterprises—are well-suited to both standardized batch processing and customized production needs.

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

High cleanliness, worry-free safety.

The triple impurity removal process—magnetic separation + vibrating screen + density-based stone removal—effectively eliminates metallic impurities, large-sized foreign objects, small-sized foreign objects, and heavy impurities, with removal rates for each type of impurity reaching or exceeding 99.5%. The purity of the raw materials is ≥98%, ensuring both production safety and product quality.

02

High-quality, polished and peeled—excellent condition.

The “two-step peeling + two-step polishing” combined process achieves a peel removal rate of ≥98%. The corn grits exhibit a bright color and a smooth surface, with an appearance far superior to that of conventional single-step peeling products, making them ideal for high-end consumer applications.

03

Simultaneous output of multiple products

Achieve the simultaneous production of three product categories—corn grits, pure germ, and low-fat corn flour—meeting diverse market demands. The comprehensive utilization rate of raw materials reaches ≥98%, thereby enhancing the company’s profitability.

04

Low loss and high efficiency, stable quality.

Flexible degerming and progressive grinding minimize material breakage, achieving a germ integrity rate of ≥95%. The particle size uniformity of corn grits and corn flour is ≥97%. The entire process is fully automated, requiring only 3–4 operators per production line, with a daily processing capacity ranging from 100 to 500 tons.

05

Flexible and adaptable process

The particle size of corn grits, the fineness of corn flour, and the purity standards for germ can be adjusted according to market demands, making it suitable for a variety of downstream applications such as food processing, feed production, and germ oil extraction.

06

Automated and precise regulation

Full-process parameters—such as peeling speed, conditioning moisture content, and grinding pressure—are dynamically adjusted in real time by intelligent measurement and control equipment. The equipment operates in coordinated fashion, ensuring batch-to-batch production consistency of ≥98% and reducing the need for manual intervention.

I. Core Operational Logic

This production line centers on a “multi-stage cleaning and impurity removal + two-pass dehulling and polishing + steam conditioning and softening + intelligent germ removal and extraction + grading, purification, grit production, and flour milling” process. to address corn's characteristics: coarse husk texture, tightly adhered germ and endosperm, simultaneous hulling and low-loss separation requirements, and concurrent production of corn grits and low-fat corn flour. It integrates core equipment like magnetic separators, sand roller hullers, iron roller polishers, and intelligent kneading embryo separators. By leveraging the differences in specific gravity, particle size, magnetic properties, toughness, and color among corn components (hull, germ, endosperm), the process achieves "physical impurity removal - hulling and polishing - Moisture conditioning - Gentle germ removal - Graded germ extraction - Endosperm grit/flour production“ workflow. This achieves ”complete impurity removal, husk elimination, intact germ separation, superior product appearance, and uniform grit/flour particle size." Strict control over hulling intensity, conditioning parameters, and grinding precision ensures ≥98% hull removal rate, ≥90% germ separation rate, ≥99% grit appearance compliance, and ≥99% purity for low-fat corn flour. This process yields three products—corn grits, pure germ, and low-fat corn flour—enhancing raw material utilization.

II. Core Equipment Synergy Logic

1. Cleaning - Dehulling - Conditioning Synergy:    Triple impurity removal via magnetic separation + vibrating screen + density stone removal.    “Two-pass dehulling + two-pass polishing” removes husks and enhances appearance.    Conditioning softens grain for “clean + high-quality + easy-to-process” raw materials for germ removal and grit/flour production.

2. Germ Removal - Grading - Three-Line Parallel Processing: After intelligent germ removal, dual-bin screening accurately diverts materials. Corn grit grading, germ purification, and endosperm milling proceed simultaneously, boosting production efficiency and raw material utilization.

3. Purification - Closed-Loop Recovery: Residual and mixed materials generated during germ and endosperm processing are recovered via dedicated equipment. Germ recovery rate ≥95%, raw material utilization rate ≥98%, with zero material waste;

4. Low-Loss Quality Control Throughout: From gentle kneading degermination and low-speed grinding to mild drying, hard contact is avoided throughout. Gradient parameter adjustments during dehulling and polishing prevent particle breakage, ensuring the quality and integrity of corn grits, germ, and corn flour.

5. Automated regulation: Real-time adjustment of all process parameters (e.g., dehulling speed, conditioning moisture, grinding pressure) via intelligent monitoring equipment. Interlinked equipment operation ensures batch consistency ≥98% while minimizing manual intervention.
