Abstract

Dry Distiller Grains with Soluble (DDGS) are a co-product of the conversion from corn into Ethanol fuel. Several applications depend on the ability of a drying process to remove moisture from a product, such as DDGS, in an effective and economical manner. Common drying methods use air to facilitate product drying as it proficiently absorbs the unwanted moisture, creating a moist-air mixture that captures both the latent and sensible heat released from the product. The most economical approach to an Air Drying System integrates a heat recovery system that transfers the heat removed by the moist-air mixture during drying back into the drying system before rejecting the moist-air mixture out of the system. The ability to condense moisture out of the moist-air mixture represents the potential energy available for recovery in the heat recovery system. This report analyzes a DDGS Air-Drying System with Heat Recovery.
