The effectiveness of sauna technique on the drying period and kinetics of seaweed Kappaphycus Alvarezii using solar drier

A sauna drying technique was designed and imposed. A V-Groove Hybrid Solar Drier (VGHSD) was constructed and tested for drying of seaweeds. Drying of sample seaweed in VGHSD reduced the moisture content from about 90.50% to 38% in 4 days at average solar radiation of about 600W/m2 and mass flow rate...
