Most of the drying room air constantly circulates through the product, while a controller determines the percentage of fresh air to be introduced for maximum efficiency, given the stage of the drying cycle.
A heat pump may be used as the heat source. Yet a lower-cost alternative with higher running cost may simply involve the use of electric elements. This is viable for short seasonal applications.
Agridry Systems make use of a heat exchanger to capture the heat leaving with the moist air, using this to pre-warm the incoming ambient air.
This system is satisfactory for most products, but the lowest humidity achievable is limited by the geographic location and the season. Coastal or tropical locations during high humidity periods are the most problematic situations as the lowest humidity achievable may not suit some products.
