SCOPE OF SERVICES
Shambaugh & Son completed this Design/Build and installation of a 40,000 CFM Critical Process Air Unit (CPAU) for an existing corn-dog production facility in Muncie, IN.
Prior to the installation of the new equipment, the food processing and packaging areas of the plant operated as a single room. The large amount of air required for the evacuation of smoke emanating from the fryers was being pulled from the surrounding areas of the facility. This resulted in negative pressures in the packaging and cook areas.
In order to ensure product quality, a new CPAU was installed to pressurize the packaging area relative to the cook room, and maintain precise space temperatures. The air that is introduced into the packaging area with the CPAU now passes into the cook room through conveyor openings, ensuring that hot moist air from the fryers does not enter into the packaging room.
Additional transfer fans were also installed between the rooms to ensure uniform temperatures throughout. A pressure differential control device modulates a VFD on an exhaust fan in the cook area to ensure that the cook room remains at a pressure that is below that of the package area (but above the unconditioned surrounding plant areas).
As exhaust hoods are shutdown or turned on, the VFD driven exhaust fan is modulated to maintain positive air pressure in both of these critical areas.
- Multi-room pressurization to ensure maintenance of critical process environments
- 95% final filters and ultra-violet lighting to ensure air quality
- Use of flooded ammonia cooling coil for precise temperature control of incoming air
- Energy efficient design utilizing VFD drives for room pressure control
- Stainless steel finishes in process areas to provide superior wash-down capability
- Extensive modification and expansion of the central ammonia refrigeration system
