Hybridized Drying System
Macrowave Express Series increases drying efficiency and line productivity while reducing carbon emissions, heat degradation and product cracking, says the manufacturer. The dryer line is suited for the processing of bedded products such as agricultural commodities, filter cakes and temperature-sensitive materials. When exposed to radio frequency energy, a product will heat throughout its entire thickness, evaporating moisture in-situ and forcing the escaping vapor to the product surface. The vapor is swept away from the product surface by the impinged hot air, leaving the product uniformly dry throughout its thickness. This moisture uniformity naturally creates a product with low water activity and eliminates the checking and surface cracks sometimes created by hot air alone.
