Through-circulation drying of seaweed. IV.—A graphical desiǵan method for continuous multi-staǵae driers

A graphical design method is proposed for calculating the drying time, throughput rates and specific evaporation for double- and triple-stage conveyor through-circulation driers. The method is illustrated with examples based on the unit wet-bulb depression drying curves for Laminaria cloustoni stipe and frond.
