This kiln is the com- mon size in New York, 20 x20 feet, and will evaporate one hundred bushels of ap- ples per day, or more if run all night. In this evaporator, two men had charge of the furnace and of six kilns that were evaporating 400 bushels per day. Fig. 261 gives the outside view of a five-kiln evaporator of this type. It shows the ventilator at the ridge, where the hot air escapes after passing over the fruit. This system is open to the objection that the fruit must be shoveled over from time to time to insure uniform drying. If not skillfully done, some will be too dry while other parts will not be dry enough. The handling itself is likely to damage some fruits. However, a skilled man overcomes these objections. The system has some very decided advantages over the tower system. Kilns are cheaper to build, are less likely to take fire, and require much less labor to operate. In some neighborhoods the tower evaporators are now being replaced by the kiln system for evaporating apples. Tower or flue evaporators.—The tower evaporators are the commonest ones in New Y'ork, where apple- evaporating has become such a great industry. They consist of a chimney-like structure of wood or brick extending from the basement of the building to a point higher than the roof. A stove. Fig. 261. A five-kiln evaporator. or furnace in the basement furnishes hot air that through the tower. The tower is usually three to four feet square and is provided wi
