GrainPro Solar Bubble Dryer (SBD)™

A Green Drying Technology

SBD50-Solar uses purely solar energy to dry agricultural commodities.
Drying is the critical first step in preserving the quality of agricultural commodities. Immediate drying of grains and seeds to the correct moisture content (MC) is an effective post-harvest practice that minimizes fungal growth and infestation.

Sun-drying is the most common method used in the tropical and sub-tropical regions of the world. The process is simple and relies on free solar energy. However, it is very dependent on weather conditions. Climate change makes weather very unpredictable and unexpected rainfall can result in delayed drying, re-wetted grains and quality deterioration. This leads to damages that reduces the market value of the commodity.

To address these problems, GrainPro™, in close collaboration with the International Rice Research Institute (IRRI) and the University of Hohenheim (UOH) Germany, introduces the Solar Bubble Dryer™ (SBD): a modern drying innovation that minimizes the effects of unpredictable weather to commodities during its drying stage.

The SBD is designed to safely dry agricultural commodities against unexpected rain and other common contaminants. Its transparent polyethylene (LDPE) cover is UV and water-resistant to safeguard the commodities as it dries. It acts like a bubble that traps solar radiation to heat the commodities. Moisture is then vaporized and pushed out by ventilators (which also maintain the shape of the bubble).

The drying floor is made of a proprietary watertight material to prevent water permeation from below. The top cover and the drying floor are joined together by heavy-duty zippers.

The SBD can dry grains and seeds at an average drying rate of 1% MC per two (2) hours for paddy and corn. During sunny weather conditions, the drying rate could be faster than conventional sun-drying.

The SBD comes in two (2) models. The SBD50-Solar comes with solar panels and relies on purely solar power to run the ventilators. It also comes with a charge controller to re-charge the battery (sold separately). Alternatively, the SBD50-Electric uses electricity from the grid.
