ABSTRACT:
A method, and associated apparatus, for drying harvested brine shrimp cysts for storage for subsequent hatching for fish food. The cysts are washed with fresh water, and strained through a sieve to remove foreign material, flotation separated to eliminate dead cysts, strained out of the water, dewatered centrifugally and finally dried in a special apparatus which prevents any caking of the cysts together. The drying apparatus includes a drum with cyst-retaining porous walls, mounted on its side to rotate in a vented housing about its longitudinal axis. Drying air is blown into the rotating drum, exiting through the porous walls, drying the cysts without caking.
