Abstract:
Solar energy can be a renewable solution for the supply of the drying heat. In combination with a back-up biomass boiler, wastes from food processing with high moisture content can be dried in a sustainable way. However, the operation of such a drying plant, which includes different sub-systems as well as many operational parameters, bears some challenges, especially in terms of the control strategy. In this regard, the process was investigated using Aspen Plus to understand the influence of the operational parameters and to provide an overview on the operational limitations of the low temperature drying system. It was shown that an overall control strategy needs to take into account the air properties (i.e. temperature and flow rate) as well as the flow rate of the wet product to provide an extensive operational range, considering the dynamic behaviors of the system, which is heavily, weather dependent.
