The core value of a wheat milling production line

1.Superior product quality and economic benefits

The primary goal of the production line is to produce flour of outstanding quality. Through the core technology of “low-temperature light grinding”, the grinding temperature is controlled throughout the process, which can preserve the natural wheat aroma and nutrients of wheat to the greatest extent, laying the foundation for the production of high-end specialty flours (such as bread flour and steamed bun flour). Pada saat yang sama, with the precise grinding and grading process, the flour yield can be stably increased to over 78%-80%, and the power consumption and labor costs can be significantly reduced, thereby increasing profit margins.

2.Intelligent and stable technological foundation

The reliability of the production line is based on intelligent control. From the cleaning stage with intelligent color sorting, to the core powder making section with multi-stage grinding and high square flat sieve, and then to the finished product processing section that achieves precise blending, the entire line is automatically controlled by a centralized PLC system. This ensures stable production parameters, consistent quality, and significantly reduces the reliance on operator experience.

3. Flexible strategic adaptability

A successful production line is not a rigid standard product, but a solution that can be deeply customized and optimized according to the characteristics of local raw grains (such as hardness, moisture, and impurities), climate conditions, dietary habits, and even the stability of power supply. Whether dealing with the high temperature and humidity in Southeast Asia, the dry and dusty environment of the Middle East, or specific wheat varieties in CIS countries, a medium-sized production line with technical expertise and customization capabilities can ensure optimal operation and production efficiency in the local area through targeted design adjustments.

Core process system for the entire wheat milling process

Cleaning and removing impurities

Fungsi: The rice sorting machine systematically removes various impurities, including large impurities (jerami, batu), small impurities (pasir, broken wheat), light impurities (wheat awns, debu), as well as adjacent stones, logam, moldy grains, and different types of grains.

Significance: This mini rice sorting machine protects subsequent grinding equipment from wear and tear, preventing hard impurities like stones from contaminating the flour and affecting food safety and taste. It is the first step in obtaining high-purity flour.

Representative Equipment and Process Essence: Utilizing a combined process of “vibrating screen (initial cleaning of large impurities) → air separator (removal of light impurities) → destoner (removal of stones based on density difference) → flat rotary screen (fine screening of broken wheat and fine impurities) → horizontal threshing machine (impact cleaning of surface impurities) → wheat washing machine (wet cleaning of adjacent stones and contaminants) → intelligent color sorter”.

Key Performance Indicators: Raw grain purity >99.9%, precise water control, beneficial for subsequent grinding.

Grinding and Sieving

Fungsi: The commercial double roller malt mill grinds clean wheat grains through multiple crushing processes, stripping the endosperm (dedak), and gradually grinding them into flour, followed by immediate sieving and grading.

Significance: Controlling the grinding material is the core of flour milling, directly determining the flour yield, flour particle size, and degree of starch damage. Grading and grinding processes maximize the extraction of high-quality endosperm.

Representative Equipment and Process Essence: Utilizing the mainstream and efficient double roller mill as the core grinding equipment, it can be used for bran grinding (stripping bran), residue grinding (processing endosperm with bran), and endosperm grinding (grinding pure endosperm) by adjusting the roller tooth profile, gap, and speed ratio. This roller milling process is the mainstream technology in the wheat milling industry. After grinding, the material immediately enters a high-square flat sieve (double-compartment flat sieve) for sieving, separating flour, dedak, endosperm, and residue of different particle sizes.

Key Performance Indicators: Low grinding temperature (temperature rise control), high sieving efficiency, and reduced starch damage.

Quality Improvement

Fungsi: The sorting machine purifies the intermediate materials (such as bran and wheat germ) after sieving, separating residual bran and extracting the purest endosperm particles.

Significance: Directly increases the yield of high-grade flour (low ash content, high whiteness), a key step in producing premium flour.

Representative Equipment and Process Essence: The core equipment is the “grinding machine.” It utilizes the combined action of vibration and controlled airflow to precisely separate pure endosperm particles, bran fragments, and intermediate materials from the bran based on differences in particle size and density. The pure wheat germ is then fed into the endosperm milling system to produce high-quality flour.
Key Performance Indicators: Precise grading, the core of which is to improve the extraction rate of high-quality flour (such as endosperm flour).

Flour Mixing and Kemasan

Fungsi: Flour Mixing: The packaging machine mixes flour base materials with different characteristics produced by different systems according to a scientific formula to form the final commercial flour.

Dust Removal: The automated packaging machine collects dust throughout the entire process, ensuring a safe and healthy production environment.

Significance: Flour mixing enables product standardization and customization; dust removal is crucial for safe production, environmental protection, and raw material recycling.

Representative Equipment: PLC-controlled flour mixing system, fully automatic packaging machine; pulse dust collectors (distributed at various dust-generating points on the production line). Key Performance Indicators: Precise formula, small packaging and weighing error; high dust collection efficiency, emissions meet standards.

Process Flow

Raw Grain Silo → Cleaning Screen (removes large impurities) → Magnetic Separator (removes metals) → Destoner (removes stones) → Color Sorter (removes moldy and spoiled grains) → Moisture Adjuster (adjusts moisture content) → Wheat Conditioner (allows resting for 18-24 jam) → Mill (multi-stage crushing and grinding) → Flat Screen/Powder Cleaner (screening and purification) → Mixing Silo (mixing according to formula) → Packaging Machine (finished product packaging)

Core Functions and Unique Selling Points

Maximizing the Preservation of Wheat’s Original Flavor and Nutrition

1.Low-Temperature Grinding Technology

The core lies in controlling the grinding speed and temperature of each mill. Through precise roller mill spacing control and excellent heat dissipation design, the material temperature rise is ensured to remain within a certain range (misalnya, 6-8°C) throughout the process. The low-temperature environment effectively inhibits the loss of volatile aromatic substances in wheat, protects the activity of proteins and vitamins in the flour, and reduces mechanical damage to starch.

2.Precise Grading and Extraction

The efficient “grinding-flat sieving-cleaning” circulation system, like a “molecular sieve,” extracts the purest and most flavorful part of the endosperm (usually with the lowest ash content) layer by layer for the production of high-end flour.

Significantly Improved Flour Yield and Economic Benefits

1.High Flour Yield

Through the close integration of “multi-stage light grinding and fine milling” and “high-efficiency cleaning and sieving” processes, as well as the recovery of residual endosperm on the bran, the total flour yield can be stabilized at 78%-80% atau lebih tinggi (the industry average is about 75%). Every percentage point increase means a huge profit margin.

2.Reduced Energy Consumption and Losses

Adopting high-efficiency energy-saving motors and optimized transmission design, the power consumption per ton of flour can be reduced by 15%-20% dibandingkan dengan peralatan tradisional. Pada saat yang sama, the efficient cleaning section reduces the energy consumption of grinding useless impurities, and precise grinding and sieving reduce the waste of high-quality materials.
