Other devices are made so that they may be suspended over a
stove, put into a stove oven, or used out of doors. Still others have a
heating device placed inside of them. It is possible, however, to make
drying devices in the home that will answer the purpose just as well as
the devices that may be bought.
[Illustration: FIG. 23]
As has been stated, drying devices should be so made that the air may
pass up through the food and across its surface. A pan, a platter, or a
solid board, as will be readily seen, is not so good for drying as a
wooden frame of convenient size that has small slats or fine,
rustless-wire netting, or screening, attached to the bottom. Such a
device may be covered with cheesecloth to keep out dirt. If it is to be
used in the oven or set in the sun, a nail driven part way into each
corner will provide feet and thus keep it from resting on the oven floor
or any other flat surface.
For suspending food that is to be dried over a stove, a rack like that
shown in Fig. 24 may be easily made in the home. As will be observed, it
consists of three trays fastened together. These trays are suspended by
four strings tied to another string that runs over small pulleys.
