A small homemade sun dryer, easily constructed, is made of light
strips of wood, a sheet of glass, a small amount of galvanized-wire
screen and some cheesecloth. A convenient size for the glass top is
eighteen by twenty-four inches. To hold the glass make a light wooden
frame of strips of wood a half inch thick and one inch wide. This
frame should have legs of material one by one and a half inches, with
a length of twelve inches for the front legs and eighteen inches for
those in the rear. This will cause the top to slope, which aids in
circulation of air and gives direct exposure to the rays of the sun.
As a tray support nail a strip of wood to the legs on each of the four
sides, about four inches below the top framework and sloping parallel
with the top. The tray is made of thin strips of wood about two inches
wide and has a galvanized-wire screen bottom. There will be a space of
about two inches between the top edges of the tray and the glass top
of the dryer, to allow for circulation of air.
Protect both sides, the bottom and the front of the dryer with
cheesecloth, tacked on securely and snugly, to exclude insects and
dust without interfering with circulation. At the rear place a
cheesecloth curtain, tacked at the top but swinging free below, to
allow the tray to be moved in and out. Brace the bottom of this
curtain with a thin strip of wood, as is done in window shades. This
curtain is to be fastened to the legs by buttons when the tray is in
place. If you have a sunny, breezy attic you can hang your drying
trays there.
The use of an electric fan is an effective means of drying. As there
is no danger of the food scorching, the fan proves as effective as the
sun for drying.
Sliced vegetables or fruits are placed on trays one foot wide and
three feet long. These trays are stacked and the fan placed close to
one end, with the current of air directed lengthwise along the trays.
The number of trays to be used is regulated by the size of the fan.
Drying by this process may be done in twenty-four hours or less. With
sliced string beans and shredded sweet potatoes a few hours are
sufficient if the air is dry.
Of importance equal to proper drying is the proper packing and storage
of the finished product. Use baking-powder and coffee cans and similar
covered tins, pasteboard boxes with tight-fitting covers, strong paper
bags, and patented paraffin paper boxes, which may be bought in
quantities at c
