Automated Fumigation Equipment for Grain Silo

As a new - generation grain storage safety solution, automated fumigation equipment for grain silo is transforming traditional manual fumigation through intelligent control and precise application technology. It is an essential tool for improving grain quality and reducing losses. This article will detail its technical principles to help us store grain better.

Why Grain Silos Need Fumigation Equipment

Pain Points of Traditional Pest Control in Grain Storage

Grain silos are vulnerable to pests and mold during long - term storage. Traditional manual phosphine application has issues like uneven distribution, high operational risks, and labor - intensive work.

automated fumigation equipment for grain silo can achieve uniform diffusion of agents through intelligent control system and directional airflow circulation technology.

Core Advantages of Automated Fumigation Equipment

Precise Dosing: Real - time monitoring of phosphine (PH₃) concentration via sensors allows dynamic adjustment of dosage. This prevents explosions from high concentrations and ineffective pest control from low levels.

Bidirectional Circulation: A fixed - pipe system supports alternating up - and down - flow gas circulation, increasing gas distribution uniformity by over 50%.

Safety and Efficiency: Reduces human exposure to toxic gases.

Technical Principles of Automated Fumigation Equipment

Intelligent Circulation System Design

Circulation Fan: A corrosion - resistant, explosion - proof fan (power ≤1kW) drives gas to circulate in a closed loop inside the silo.

Application Device: Supports cylinder - mixed gas (PH₃+CO₂) or external phosphine generator application, eliminating manual entry.

Detection System: Integrates gas concentration sensors and temperature - humidity probes, transmitting data in real - time to a central control platform.

Intelligent Control Process

Automatic Application: Triggers dosing based on preset concentration thresholds, minimizing human intervention.

Bidirectional Circulation Mode: Alternates up - and down - flow every hour through butterfly valve combinations, ensuring gas penetration in all grain layers.

Remote Monitoring: Allows real - time data viewing on PC or mobile devices, with automatic alarms for anomalies.
