Bulk Grain Storage

Safe storage · moisture & pest proof · long-term quality

Challenges in grain storage

Long-term bulk storage faces multiple risks: moisture rebound causing mold, day-night temperature swings causing wall condensation, pest and rodent damage, and local "hot spots" triggering spontaneous combustion. A sound storage plan must be designed across three dimensions, silo selection, temperature-controlled ventilation, and automated loading/unloading, not just picking a silo.

Silo selection guide

Flat-bottom steel silo

Large single-silo capacity (500–10,000+ t)
Lowest unit storage cost
❌ Needs mechanical cleaning (sweeping auger)
For: long-term bulk storage, low-frequency turnover (1–2 cycles/year)

Cone-bottom steel silo

Gravity discharge, no cleaning equipment needed
Fast unloading, suited to frequent turnover
❌ Smaller single-silo capacity (50–300 t)
For: raw-material silos at processors, high-frequency turnover silos

Square steel silo

Square structure, maximizes site space
Can be mounted flush to walls and corners
Modular assembly, expandable as needed
❌ Needs auxiliary discharge device
For: in-workshop installation, processing by-products / feed raw materials, space-limited sites

Core auxiliary systems for storage

Temperature-controlled ventilation

Multi-point temperature cables monitor in real time + automatic ventilation/dehumidification. In-silo temperature difference held within ±3°C, fundamentally preventing condensation and "hot spots". Mobile remote monitoring optional.

Automated loading/unloading

Bucket elevator + scraper conveyor + belt conveyor combination, sized to the silo group. Full automation from truck unloading to silo storage, reducing labor dependence.

Protection & fumigation

Silo reserved with phosphine fumigation port, bottom moisture barrier + roof waterproof seal. Insect screens and rodent guards build a physical + chemical dual-protection system.

Silo capacity planning reference

Scenario	Recommended total capacity	Recommended silo type	Recommended number
Small farm	100–500 t	Mainly cone-bottom	2–4 silos
Medium cooperative	500–2,000 t	Flat-bottom + cone-bottom mix	3–6 silos
Large collection center	3,000–10,000+ t	Mainly flat-bottom	4–12 silos

Frequently Asked Questions

Flat-bottom or hopper-bottom silo — which should I choose?

Flat-bottom bolted silos cover 500-10,000+ tons with the lowest unit storage cost, suited to long-term, low-frequency turnover (1-2 cycles/year) but need a sweep auger to clear out. Hopper-bottom silos cover 50-300 tons with gravity discharge and no cleaning equipment, suited to high-frequency turnover such as processor raw-material bins. Choose by turnover frequency.

How do you prevent mold and condensation in stored grain?

Silos come standard with multi-point temperature cables for real-time monitoring plus automatic temperature-controlled aeration, holding in-silo temperature difference within +/-3C to fundamentally prevent condensation and local hot spots. A bottom moisture barrier, roof waterproof seal, insect screens and rodent guards form a physical plus chemical dual-protection system.

What total capacity and how many silos do I need?

Small farm 100-500 t (mainly hopper-bottom, 2-4 silos), medium cooperative 500-2,000 t (flat + hopper mix, 3-6 silos), large collection center 3,000-10,000+ t (mainly flat-bottom, 4-12 silos).
