Regenerated desiccant devices for cooling stored grains
About 10% of all food grains that are harvested are ruined by insects and moulds during storage. One method of protecting stored grains is to cool them, as this reduces biological activities such as insect pest reproduction and mould growth. Cooling grains also reduces that rate at which moisture …

Inline disinfestation of canola seeds from red flour beetles using a 50-ohm RF technology
Disinfestation of insect pests in stored grains is a crucial unit operation to save the quality of the grains during the storage. Several methods of disinfestation are available including chemical and non-chemical methods. However, the use of the chemical method is avoided because of its adverse …

Modelling the microclimate in a conical bottomed circular grain silo
… predicting the behaviour of microclimate in the stored grain silo is presented. This analysis is implemented by calculating the air pressure field within an aerated conical bottomed circular silo, to continuing prediction the velocity field. The obtaining results are used to compute the …

Design and Development of a Low-cost Acoustic Device to Detect Pest Infestation in Stored Maize
Insect damage in stored maize is one of the major post-harvest losses occurring in developing countries, especially in sub-Saharan Africa. To reduce economic losses, separation of infested grains from clean ones is critical and requires detection of infestation in stored grains. This study aimed at …

When the Waters Came
… floating in the currents. Silos were crushed and stored grains were contaminated, losing seasons of labor in a matter of days. But even when the water receded and returned to the confines of its banks, there was no relief for farmers like Jeremy Mahon and his family. Ranchers and farmers are still …
