The technology uses one drier head for multiple containers, while the same container is used to hold grain for drying and storage, which makes it affordable.

It reduces drudgery because there is no movement of grain for drying and storage and there is a possibility for periodic air circulation during storage for pest control. The capacity tested ranges between 1 and 30 bags but there is a possibility to have bigger sizes.

About the Project

Research Summary and Technology

The hybrid solar desiccant drier combines solar and desiccant drying to achieve rapid drying, even on cloudy days and at night. It is designed to be airtight, making it hermetic and preventing aflatoxin contamination, as well as preventing pest and rodent infestation.
