ABSTRACT:
An enhanced apparatus and method for cleaning, drying, and disinfecting brine shrimp eggs is provided. The apparatus may have a blower and a furnace that provide pressurized, dry air to a screening device. The screening device may include a vibrating screen designed to release detritus while retaining viable cysts. The dry air may convey the cysts upward and suspend them within a containment vessel. The containment vessel may have a lower, narrow section and an upper, wide section; the larger airflow velocity within the narrow section suspends the brine shrimp eggs while the remaining detritus moves upward, into the wide section, in which the airflow velocity is lower. The air suspension rapidly dries the cysts to maintain a high percentage of viable eggs. Ultraviolet lights disinfect the cysts within the narrow section. An extractor with a cyclone separator draws material from the wide section and removes viable eggs from the detritus.
