Most large-scale industrial distillers grains drying is done on concurrent convective dryers where the wet material and heated drying gas pass together through the equipment. High inlet gas temperatures can be used without damaging the material because the surface moisture on the wet feed rapidly evaporates at the dryer inlet. This lowers the gas temperature
An industrial dryer is an essential part of most material processing procedures, but they are typically a large capital expense and can last for decades. This makes picking the best dryer for your processing needs especially important since picking the wrong dryer can have long term negative consequences for both material quality and company finances.
