r is allowed to return to the room before it is cooled. The position of the portable unit must be chosen to direct the warm air to the intake of the cooling system to prevent condensation on producealready cooled. In the case of permanent fans, the containers must also be rearranged after cooling to prevent possible dehydration. Cold wall cooling systems are more complex form of forced-air cooling but are very exible with regard to the time that different types of produce require for adequate cooling and the time at which they arrive (Fig. . The main constraint is that pallets need to be moved as soon as they are cooled in order to prevent dehydration of the contents. false wall is constructed, creating permanent air plenum between the real wall andthe false wall. This plenum is equipped with exhaust fans that circulate air across thecooling coils. Air inlets are located on the false wall but are not opened until pallet loadis placed up against the wall. Dampers control the air inlets so that they remain closeduntil pallet load or stack is placed up against the false wall. good damper design allows different types of packages or partial pallets to be used. The false wall may be built with shelves so that several layers of pallets may be cooled (. Fig. 5 Schematic of cross-sectional view of cold wall cooling system. Cooling and Storage 5 Serpentine cooling, modication of the standard cold wall cooling method, is used for cooling pallet bins. Although the bins must have bottom ventilation, side ventilationis not necessary (. Several rows of bins are pushed up against the false wall, each rowhaving several layers. The number of rows that can be used is dependent on the desiredcooling speed and the ow rate that is available. The openings on the pallet bins for the forklift are used as air supply and return plenums. Every second layer of the forklift open- ings that are facing the cold room is covered to prevent air from entering. Likewise, everysecond la
