Improvements in conveyor drying of rockweed and kelp

The drying industry in Iceland is a rapidly growing industry where new technology has been applied in recent years. Seaweed drying is an energy intensive process which requires considerations regarding the utilization of raw material. For better control of this utilization a mass and energy balance...
