Scope of application

Suitable for large-scale applications such as food processing plants and deep-processing bases for agricultural products, this equipment can professionally hull and purify various types of sweet buckwheat, including common sweet buckwheat and large-grain sweet buckwheat, meeting the production needs of multiple sectors—including sweet buckwheat rice, snack foods, deeply processed products, and specialized health foods.

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.

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.

Technical Features

Sweet buckwheat has strong adaptability.

The HuaYu Wantong flexible polishing machine is custom-designed specifically for sweet buckwheat’s characteristics—“thin shell and high fragility.” It features ultra-soft rubber rollers combined with a low-speed design, striking a perfect balance between hulling efficiency (≥96%) and kernel damage rate (≤2%). This addresses the common pain points of conventional equipment, which either leave residual hulls or produce excessive broken kernels.

The finished product is of excellent quality.

After undergoing “three-stage purification + flexible hulling + double refining,” the finished sweet buckwheat rice boasts a purity level of ≥99.5%, with uniform color and a smooth, glossy surface. It has a clean, sweet taste free of impurities, meeting high-end food processing standards.

Nutrients fully preserved

Made entirely through physical processing—without any chemical additives or high-temperature and high-pressure treatments—this product fully preserves core nutrients such as tartary buckwheat protein, B vitamins, and dietary fiber, aligning with the trend toward healthy food production.

Automated effective operation

The entire process—from raw material delivery to finished-product storage—is fully automated and interconnected, with a daily processing capacity ranging from 100 to 500 tons. This reduces manual intervention, minimizes human error, and ensures batch-to-batch production consistency of ≥98%.

High raw material utilization rate

Unhulled sweet buckwheat is returned for a second hulling process. The broken grains can be recycled for processing into sweet buckwheat flour and sweet buckwheat noodles, ensuring zero material waste and achieving a comprehensive raw-material utilization rate of ≥97%, thereby enhancing economic benefits.

Easy to operate and maintain

Device parameters are centrally controlled via a frequency conversion system. The Huayu Wantong flexible rubbing rollers are wear-resistant and durable, easy to disassemble and clean, thereby reducing subsequent maintenance costs and downtime.

Working principle

I. Core Operational Logic

This production line centers on “flexible physical hulling + precise grading and purification.” Addressing the characteristics of sweet buckwheat—thin, moderately tough hulls and plump, easily damaged endosperm—it leverages coordinated equipment to exploit differences in particle size, specific gravity, color variations, and the contrast in toughness between the thin, brittle husk and the resilient endosperm. Through a comprehensive physical process encompassing "conveying - multi-stage purification - flexible hulling - density sorting - optical sorting - sealed preservation." This achieves complete impurity removal, gentle hull separation, and standardized sweet buckwheat kernel output without chemical additives or additional softening treatments. It balances hulling rate (≥96%), kernel integrity (damage rate ≤2%), and nutrient retention to meet large-scale production goals.

II. Equipment Synergy Logic

1. Purification equipment (vibrating cleaning screen + destoner) progressively removes large impurities, small impurities, and heavy impurities, providing “clean and uniform” raw materials for flexible hulling. This prevents impurities from causing uneven hulling or equipment wear.

2. Huayu Wantong's flexible polishing machine and sorter operate in tandem, recycling unhulled sweet buckwheat for secondary processing to enhance hulling efficiency. Post-polishing, the clean surface of sweet buckwheat kernels improves optical sorting accuracy by over 20%, reducing misclassification.

3. The entire process integrates equipment parameters (conveyor speed, vibration frequency, hulling gap/rotation speed, color sorting threshold) through variable frequency systems and infrared monitoring. This achieves seamless integration of “conveying - purification - hulling - refinement - storage,” ensuring batch consistency ≥98%.
