If food is to be dried by the stove-drying method, it may be placed in the oven, on top of the stove, or suspended above the stove.

If the oven is to be used, a device that fits the oven should be employed. Spread the food on the trays in single layers, and put the device into the oven. The temperature of the oven demands attention in this method. Only a very moderate heat may be applied at first, 110 degrees Fahrenheit being considered the ideal temperature for beginning.

As it is difficult to hold an oven at such a low temperature if a fire is burning, the oven door should be left open to admit air. The temperature of the oven of a coal stove in which the fire is banked or is being allowed to go out is usually ideal for drying foods. If desired, the heat of an oven may be gradually increased to about 180 degrees as the food dries; but the application of greater heat is liable to scorch the food and injure its flavor. The food must be turned often to permit it to dry evenly.

If food is to be dried on top of the stove, the device shown in Fig. 23 will prove satisfactory. The same arrangement may be improvised by placing a metal tray over a large flat vessel of water. Place the food to be dried in a single layer on the tray over the water. Let the water boil and keep it boiling, and turn the food frequently so that the heat will be applied to all sides. Continue this process until the food is leathery, when it may be stored.

If food is to be dried in a rack suspended above the stove, a rack like that shown in Fig. 24 should be used. Cover the trays in the rack with a single layer of food, and dry it to the leathery stage, when it may be removed and stored. In using this device, only a coal or a wood stove is practical.

When the heat coming from the stove is not great, the rack may be allowed to come close to it, and when the heat is intense the rack may be drawn up. Regulating the distance of the rack from the stove will tend to keep the food at a uniform temperature and allow it to dry evenly, especially when the food is turned from time to time.

ELECTRIC-FAN DRYING METHOD.--If a house is wired for electricity, drying foods by means of the air-currents generated by a moving electric fan is a simple matter. Use devices like those required for the sun and oven-drying methods. Spread the foods to be dried on the trays in a single thin layer, and arrange them so that the air from the electric fan will blow over them.

Turn the trays as the food dries, so that one part does not dry sooner than another; also, turn the food frequently so as to expose all parts alike. If the fan can be placed so as to blow across a stove and thus blow heated air on the food, it will dry more quickly. A very warm kitchen is an excellent place in which to do the work with an electric fan, as the combination of air and heat does the work more rapidly than either one used alone.

COMBINATION DRYING METHODS.--A combination of any of the drying methods mentioned may be used effectively. Drying may be started in the sun and completed in the oven, or it may be started with an electric fan and completed in the sun or the oven. Any means whereby the time required for drying may be shortened is advantageous.
