A scientific selection of fumigation equipment for grain silo can reduce pest - related losses by over 90%. Based on global experience from over 300 grain silo projects, HKB will explain the scientific logic behind choosing automated fumigation equipment.
Pressure half - life ≥250 seconds: Through positive - pressure testing (initial pressure of 500Pa), the time for internal pressure to halve must exceed 250 seconds. This ensures effective retention of fumigant gas.
Matching formula: Airflow (m³/h) = Silo capacity (m³) × 0.3 - 0.5 (circulation factor).
Recommended standard: For a 1000 - ton silo capacity, a blast - resistant fan with an airflow of ≥1000m³/h is needed. This ensures uniform gas distribution and concentration error <5%.
316 stainless steel: Suitable for high - humidity, high - corrosion environments (e.g., coastal areas), with a lifespan of up to 15 years.
Corrosion - resistant PVC - U: Reduces costs by 30%, suitable for dry areas (average annual humidity <60%), and can withstand temperatures from - 20℃ to 60℃.
IoT remote operation: Supports real - time monitoring of gas concentration and temperature - humidity via mobile phone or PC, and automatically adjusts circulation frequency.
HKB's intelligent system can shorten fumigation time from the traditional 72 hours to 48 hours, reducing energy consumption by 25%.
When selection of fumigation equipment for grain silo, consider other aspects:
Real - time monitoring of phosphine concentration via infrared sensors, with fluctuations controlled within ±5ppm (national standard allows ±20ppm).
Gas leak alarm threshold set at 0.3ppm (1/10 of OSHA safety standard), triggering automatic activation of ventilation systems.
The intelligent control system records data from each fumigation process. By analyzing this data, future fumigation operations can be optimized to improve efficiency and reduce resource waste. For example, the system can predict the optimal fumigation time and gas dosage based on historical data, further lowering operating costs.
When selection of fumigation equipment for grain silo, different parameters should be selected for different grain. There is a 30% difference in fumigation parameters between wheat and rice, necessitating customized programs.
Non - explosion - proof fans have a failure rate six times higher than dedicated equipment, posing explosion risks.
