REFRIGERATOR CARGOES 415 shows a side elevation, the small squares being peep holes, fitted with sliding shutters, for inspection of the fruit One ripe banana generates heat which sets up a "nest" or centre of ripening fruit which will quickly spread throughout the whole bin unless it is removed. The lowei part of the figure shows in plan the breadth of a ship with msulated hold and bins side by side* ARRANGEMENT Of REFRIGERATING PLANT BANANA BOAT Fig 8.—Side View and Plan of Bins and Ventilating System. The refrigerating plant circulates cooled brine through nests of pipes which reduce the temperature of the air in contact with them* The cooled air is circulated through the fruit chambers by powerful fans driven by electric motors. The air is driven into the air trunk which forms a passage-way between the ship's side and the bins, afterwards passing through the fruit chamber and returning to the circulating machine.
