DRYING ON TRAYS.
For convenience in handling, wooden or paper trays are commonly used for drying figs in the Western States. By their use the fruit can easily be stacked and sheltered in wet weather. The trays are of various sizes, but a small size, such as 2½ feet by 3½ feet, or 3½ feet by 4 feet, is preferable, as when filled with fruit it can easily be handled by one man, while a larger size requires two men. The drying ground should be a clean space outside the orchard, where the trays may be exposed to the uninterrupted rays of the sun. The figs require all the sunshine obtainable, and the drying ground must therefore be free from the shade of trees or buildings. The drying floor may consist simply of beds of soil elevated a foot above the general level. A drying floor 4 feet wide may be raised 8 inches additionally along one side. The slope toward the sun thus given will insure greater heat. Trays may be placed on strips of wood or scantlings supported by low sawhorses. The sawhorses should be long enough to support two rows of trays abreast. Three scantlings or strips will be required for each pair of sawhorses. They should be of even lengths, as long as obtainable, and the middle one should be larger than the outside ones; 2 by 4 inches for the middle one and 2 by 3 inches for the side scantlings will be found convenient sizes. The figs should be placed singly on the tray, with their eyes all toward one side, and this side of the tray should be slightly raised in order to prevent the contents of very juicy figs from running out during the process of drying. The raising of the trays is the most easily accomplished by placing the 2 by 4 inch supporting strip in the middle of the sawhorses and the 2 by 3 inch strips on either side. Immediately after sulphuring, if that is practiced, or after dipping, the fruit should be spread and the trays distributed on the racks where they will have the full benefit of the hottest sun. This distribution of the trays should be finished before noon each day to secure the best color of the dried product.
The figs must be turned twice a day at first and once a day in the later stages of drying. The turning requires much work and expense, as it can be done well only by hand labor. An inferior product may be turned by placing an empty tray face downward upon a filled one and inverting them, leaving the fruit on the new tray. To produce the best grade of dried fruit, the figs should not touch one another on the trays during the process of drying. During the turning, all inferior figs, such as those that ferment and puff up, should be culled out and used for vinegar. Figs which show a slight froth at the eye are turning sour and should be removed.
Covering the figs must not be neglected, if a choice article of dried fruit is to be produced. If white figs are left out over night uncovered, they will be discolored. Rain and dew are very damaging and the fruit should be protected from them. This is best accomplished, in California, by stacking the trays one on top of another when rain is expected. The top and sides of the stacks should then be protected with empty trays. If permanent drying beds of gravel and cement are made, a mechanical device for covering the trays with a horizontal canvas curtain can be used, and in this way they can easily be covered every night.
