Post-harvest losses refer to grain losses occurring from harvest to consumption due to improper handling, outdated equipment, or poor storage conditions. According to statistics, global post-harvest grain losses range from 10–20%.

Modern grain processing equipment reduces losses by:

• Efficient cleaning equipment: Removing impurities to minimize waste in subsequent stages.
• Precise grading equipment: Sorting by size and density to ensure processing consistency.
• Temperature-controlled drying equipment: Replacing natural sun drying to prevent mold and pests.
• Airtight storage systems: Protecting against moisture, rodents, and insects to extend shelf life.

Grain cleaning refers to removing various impurities from raw grains, including organic impurities (straw, weed seeds, moldy kernels), inorganic impurities (sand, stones, dirt), and foreign grains. The necessity of cleaning includes:

• Ensuring product quality: Impurities affect the purity, color, and taste of final products.
• Protecting processing equipment: Hard objects like stones can damage key components such as rollers and screens.
• Ensuring food safety: Metal contaminants and moldy kernels may pose health risks.
• Improving yield: Cleaned grains result in higher milling efficiency and finished product rates.

A complete cleaning process typically includes: pre-cleaner → vibrating screen → destoner → magnetic separator → gravity separator.

Capacity determination should consider:

• Raw material availability: Daily processing volume should match your supply capacity.
• Market demand: Estimate daily sales; it's advisable to have capacity slightly above current demand to accommodate growth.
• Operating shifts: Single, double, or triple shifts affect daily output.
• Product type: Different grains (corn, wheat, pulses) process at different rates.

Typical capacities: small-scale lines 10–50 tons/day, medium-scale 50–200 tons/day, large-scale 200–1,000 tons/day. If unsure, provide your raw material type and target output, and our engineers will recommend the appropriate configuration.

Modern grain processing typically includes the following core processes:

Yes, but with considerations:

• Corn vs. wheat: Different processes—corn requires degermination, wheat requires conditioning; adjustable screen sizes and roller gaps are recommended.
• Pulses vs. cereals: Pulses are harder with irregular shapes; air flow and screen openings need adjustment for cleaning and grading stages.
• Changeover cleaning: When switching grain types, thoroughly clean equipment internals to prevent cross-contamination.

If you plan to process multiple grain types, inform our engineers during purchase, and we will recommend a more compatible configuration.

Space requirements depend on equipment configuration and capacity:

• Small-scale (10–30 tons/day) : 100–200㎡, height ≥6 meters.
• Medium-scale (50–100 tons/day) : 300–500㎡, height ≥8 meters.
• Large-scale (200+ tons/day) : 800–1,200㎡, height ≥10 meters.
