The Small-Farm model has three main features which enhance drying speed and efficiency. This compact configuration provides for:
â€¢ Horizontal airflow across the food is proven superior versus vertical airflow.
â€¢ Solar air collector tilts to accommodate any latitude or season.
â€¢ Entire dryer can swivel on a fixed table so operator can rotate unit to track the sun.
Large commercial dryers, or their solar air collectors, are unable to be rotated during the day to track the sun. This limitation also favors multiple small units.
Advantage of solar air collector
Solar air collector is a specific collector developed by Dryfree solar from 2009.Different from the traditional solar collector
using the water as the heat transfer fluid, solar air collector heats the air directly by using the air as heat transfer medium.
Air drawn through the system absorbs the collectorâ€™s heating,rising in temperature by as much as required temperature, and then
the warm air returns to the drying chamber for the drying operation, or passes into the living room for heating. Solar air
collector can be widely used in industrial and agricultural drying and spacing heating, etc.
