Abstract:

The separator/dryer includes a housing, removable collection trays, a separator assembly, a rinse assembly, and a heater/blower. The separator assembly separates the ammunition casings from the clean media and the rinse waste and includes a rotating separator basket disposed within the housing on a motor driven shaft. The rinse assembly provides a water shower to rinse any cleaning residue, carbon particulate and dust from the ammunition casings and the cleaning media. The heater/blower circulates a stream of hot air into the housing interior to dry ammunition casings and the cleaning media. The removable collection trays are vessels for collecting both the rinsed and dried ammunition casings and the rinsed and dried clean media.
