Structural Advantages of Soybean Meal Silo
As the core equipment of modern warehousing, the soybean meal silo achieves three core advantages through a cylindrical steel structure design:
The space utilization rate has increased by 40%
Standardized silos with a diameter of 8 to 12 meters can store 200 to 500 tons of soybean meal, saving land area compared to flat silos
Anti-deterioration double insurance system
Equipped with a humidity sensor (accuracy ±2%RH) and an axial flow fan, the moisture content of soybean meal can be stably controlled below the 12% safety line
Mechanized operation efficiency
The matching screw conveyor (15-30 tons per hour) and automatic weighing system have increased the efficiency of inbound and outbound operations by three times
Standardized Clearance Operation Procedures for Soybean Meal Silo (Including Safety Points)
Stage 1: The pretreatment stage is expected to take 2 to 4 hours.
Close the feed inlet and hang the “Operation warning sign”.
Turn on the bottom vibrator of the warehouse (with a recommended frequency of 15Hz) for initial loosening
The concentration of hydrogen sulfide in the detection chamber (should be less than 10ppm)
Phase 2: Mechanical Clearance (Core Operation)
Use a dedicated warehouse clearance machine to spiral down along the warehouse wall (with the speed controlled at 0.5m/min)
Pause the inspection every 2 meters of thickness to prevent arching and collapse
Switch to manual cleaning mode when the residual amount is ≤0.3%
Stage 3: Quality Inspection
The sampling points are distributed according to the “upper, middle and lower three-layer five-point method”
The fluctuation of the detected protein content should be ≤1.5%
Key Control Points for Soybean Meal Storage
Environmental parameter threshold
Temperature: ≤25℃ (The top sprinkler system of the warehouse needs to be activated in summer)
Relative humidity: The range of 55% to 65%
Stacking height limit: ≤8 meters (to prevent compaction and caking)
Pest control management
Phosphine fumigation (concentration 200ppm×72 hours) is carried out monthly.
Before being stored in the warehouse, impurities are removed through a 60-mesh sieve
First-in, first-out principle
It is recommended to adopt an RFID tag management system, and the storage period should be strictly controlled within 90 days
【 Special Note 】 Flaw detection and inspection of the welds of the warehouse body should be carried out every quarter to prevent structural stress cracking
