ABSTRACT:
A protection system for a conveyor for items, such as food items, is provided to keep the conveyor free from bacteria and other contaminants which may accumulate and build-up on the conveyor track and track traversing components. The protection system includes a shroud surrounding the conveyor to which pressurized, bacteria-free air is fed. A preferred bacteria removal unit is a filtration unit to filter bacteria from the ambient air. Herein, a combination filter and blower unit is disclosed which finely filters ambient air, preferably down to 3 microns, and pressurizes the air and blows it into an air manifold connected to the shroud by a series of air ducts. The shroud walls cooperate to form a slot through which the meat hangers can extend and for allowing the clean air in the shroud to be continually flowed therethrough and circulated around the conveyor components. A cleaner, such as a steam cleaner, can be located at a predetermined position along the track between the unloading and loading stations for the meat transported by the conveyor. The protection system herein advantageously keeps the conveyor clean and sanitized during conveyor operations without requiring costly conveyor shutdowns for cleaning and maintenance.
