In farm operations, storage is where profits quietly leak—or quietly accumulate. The Feed Silo Metal Silo Galvanised Feed Tower For Poultry House from Jinwang Western Street, Industrial Zone, Anping County, Hengshui, Hebei (China) is one of those workhorse solutions that, to be honest, doesn’t shout. It just works. And when farmers tell me they want fewer blockages and cleaner discharge, a silo automatico with a hopper bottom is usually the first thing I suggest.
Three trends keep coming up: corrosion resistance (galvanised steels with higher zinc layers), smart level sensing, and—this is big—clean discharge. Hopper-bottom designs with a 55–65° cone angle reduce residue and cut labor. It seems that many customers now expect plug-and-play integration with augers or pneumatic feed lines.
| Parameter | Typical Value |
|---|---|
| Material | Galvanised steel (Q235 or similar), zinc layer ≈ Z275–Z450 g/m² |
| Capacity Range | ≈ 5–100 m³ (real-world use may vary by bulk density) |
| Hopper Cone Angle | ≈ 60° for free-flowing grains; options for feed pellets/flour |
| Discharge | 300–400 mm outlet; auger or gravity, self-cleaning, low residue |
| Fasteners & Seals | 8.8-grade bolts, EPDM gaskets, anti-leak corrugated joints |
| Design Life | ≈ 15–25 years with routine maintenance |
| Typical Loads | Wind ≤ 0.6 kPa, seismic per local code (check site conditions) |
For poultry houses, a silo automatico with a hopper bottom means consistent feed flow, less bridging, fewer climbs to knock clumps loose. For seeds and flour, the smooth discharge and easy clean-out cut cross-contamination risks. Many customers say they appreciate the simple visual level check (paired with a sensor, even better) and the quick install.
| Vendor | Corrosion Protection | Lead Time | Certifications | Customization |
|---|---|---|---|---|
| Yize Machine (Hebei) | Z275–Z450 zinc (option) | Around 3–6 weeks | ISO management; CE on structures where applicable | Cone angle, outlets, sensors, ladders |
| Generic Importer A | Z275 typical | 8–10 weeks | Basic factory QC | Limited options |
| Local Fabricator | Varies by stock | 2–4 weeks | Depends on shop | High, but price varies |
A midsize poultry operator upgraded to two 25 m³ units; feed bridging dropped to near zero, and staff time on roof checks disappeared once level sensors went in. Another site handling feed pellets and cracked corn reported cleaner changeovers thanks to the cone’s self-emptying profile—surprisingly, they also noted quieter auger operation, likely because fines build-up fell.
