Innovative air ducting systems for grain aeration and pest control

Overview

This innovative air ducting system revolutionizes grain storage by achieving uniform air and fumigant distribution, particularly in the dense, central regions of silos. By enhancing aeration, the system effectively reduces the risk of insect pathogenic bacteria and mold development, ensuring better grain quality and safety. Additionally, the ducting system is energy efficient, lowering the specific energy consumption of the fan and ventilation systems. As a result, it minimizes insect and mold growth, reduces microbial load, and optimizes fumigation during infestations, leading to safer and longer-lasting grain storage.

Technical specifications

Designed with advanced inlet air ducts labeled E, F, and H, this system successfully directs air and fumigant gases into the central parts of grain storage systems. This ensures uniform and rapid gas distribution and cooling, crucial for effective grain preservation. The system addresses common challenges such as uneven distribution caused by chaff and foreign materials. Future validation includes scaling the technology to real-size silos, constructing prototypes to test performance under realistic conditions, and assessing its efficacy in reducing insect and pathogen presence using aeration and fumigants like phosphine or ozone.

Technology readiness level

Currently at Technology Readiness Level 4, this air ducting system has undergone lab-based validation. Future plans involve further testing and refinement through prototype construction and real-world application to demonstrate its full potential.
