Pallet loads of strawberries are placed at the two sides of the wall blower so as to allow a plenum (air-chamber or passageway) for air being drawn through produce to the blower. sons, et. al, 1970, 1972). This difference forces air through the stacks and carries produce heat away primarily by flow around the individual fruits or vegetables in the containers (figs. 18- 22) , rather than by flow around the outside of the containers (as in room cooling) . In forced-air cooling, cooling speed can be regulated by adjusting the volume of air. Rapid cooling can be accomplished with adequate refrigeration and a large volume of air flow per unit of produce. Using a large air volume to speed forced-air cooling reduces area of floor Fig. 21. Forced-air cooling unit in operation with pallet loads of strawberries. The fabric cover in front seals the air-return plenum, and air is thus forced to pass through side slots of containers and around the fruit in order to return to blower. The blowers used in this procedure are controlled by time clocks. ^. 15.
