Abstract
An automated processing freezer system is described that provides a plurality of cooling units to chill the air within a freezing enclosure, whereby the coils of each cooling unit may be defrosted independently, without louvers or other moving mechanisms, while the cooling output of the freezer system is maintained 24 hours a day. Baffles in the freezing enclosure isolate each cooling unit from the airflow associated with the other cooling units, thereby eliminating the need for expensive and less efficient louvers surrounding the coils of each cooling unit.
