Table Type Sun Drying for Seaweed Preservation

Abstract:

Open sun drying is one of the oldest techniques employed for processing agricultural products. The local practice of drying the seaweed is by spreading it over a plastic sheet on the ground and exposing it to the sun. Unfortunately, such traditional practice of drying seaweed has led to increased risk of contamination of seaweed by dust and sand particles and other impurities, as well as seaweed often suffer from lower quality. This research was conducted to examine the effect of application of table type sun drying on quality of dried seaweed, through indicators of water content, level of impurities, and brightness. The dryer was designed by using aluminum as a drying surface, with holes for circulation. The surface of aluminum is blackened to increase temperature. The results of study showed that table type sun drying reduced water content rapidly, reduce level of impurities, and improve brightness of dried seaweed.
