Abstract

Tests on the through‐circulation drying of Ascophyllum nodosum on a semi‐commercial scale have been conducted with a batch dryer to determine the optimum conditions. It was found that there was a maximum feasible loading for rockweed of 80% initial moisture content of approximately 8 Ib./sq. ft. in each layer and that four layers were enough to insure full use of drying air at an air mass flow of 20 Ib. dry air/min./sq. ft. The effects of variations in the fraction of air recirculated, air‐flow reversal, and temperature (160–220° F) have been studied with particular reference to output and thermal efficiency. High outputs were recorded at heat consumptions of <2500 B.Th.U./Ib. of water evaporated.
