COLD STORAGE ROOM.
The Principles Involved and the simple
Plan of Construction.

Plan of Construction.
The cold storage system is gradually
growing into favor as its practicability
becomes known. Where q constant
low and dry temperature can be main
tanned the principle is no longer a Sc
cret Nor is it necessary that the room
be made of any particular size or form.
1t must, however be thoroughly in
si,ll:sssss. "a regard to keeping the walls
impervious to circulating currents OF
air, except those necessary for ventila-
tion, which should be small and per-
fectly controllable. A plan OF very
good room is given by tho California
Fruit Grower, as follows: Erect a
frame lined upon the inside with heavy
paper and vanished with shellac, then
ceiled and noored with tongue and
grooved material, 5-8 or 3-4 inch thick.
Yarnish the entire inner surface. Be-
fore putting down the paper lining and
floor, fill in between the framing dry
sawdust and pulverized charcoal mixed.
Board up the outside with tightly
matched boards, filling in as you board
up with the sawdust and charcoal, as
well as every part OF the top. excepting
the door for putting in the ice.
The door for entrance to the room
must be made TO slut against broad
jams and angular closures like an iron
safe, so that it can not stick by swell
ing. 1t should be made by framing and
packing with sawdust and charcoal, in
the Same manner as the room, which
should be from u to Is inches between
the walls. Frame an opening in the
ceiling large enough to let in galvan-
lied sheet-iron box of sufficient size to
hold as much ice as you may wish &c
store, or about onc-tenth Of the capacity
of the whole room. The ice-chamber
should be fitted into the opening tight,
with Hange all around the top. II
may be made of No. Is or 20 galvan.
lied sheet-iron. TO the bottom attach
coil of galvanized iron or lead pipe,
running two or three times around the
room, hanging on hooks or brackets,
just below the level OF the ice-box.
Pass the end of the coil through &c
the outside of the room and termi-
nate in an inverted siphon, SO as
to retain the water within the coil
up to level just below the bottom
OF the ice-box. This is for the purpose
of economizing the cold from the waste
water by circulating it around the
room. From the cross beams of the
ceiling, as bearings for the weight ol
the ice, place two or three straps oi
square iron. of size sufficient for car.
rying the weight of the ice you intend
putting in. Let them hang upon the
inside of the galvanized iron box tC
within an inch of the bottom. Upor
these straps lay a hardwood grating.
Make a galvanized iron cover to I'll
tightly over the leo chamber, and q
wooden one to close over the iron one.
To prevent the water which may be con
densed upon the outside OF tho ice.
chamber from dripping down upon the
goods, mako the bottom of the ice
chamber bulge downward, so that the
condensed drops will run to the center
or one side, where a small pan may be
hung with q small pipe leading to tho
outside of the cold room and a siphor
attached to prevent ingress OF air. The
ice chamber may now be charged with
its full capacity of ice, and If a very
cold room is required, sprinkle a layer
of salt between each layer OF ice Thi:
is seldom used for such rooms.
The principle upon which this colo
room is constructed is that there shall
be no communication between the ice
with its moist vapor and tho air OF the
cold room. ANY moisture made by
cooling OF the air, and which is pre-
cipitated upon the iron surface Of the
ice chamber, is at once conveyed out
of the room by the drip pan and its
pipe. Hence there is no need of amy
special ventilation. more than what will
naturally occur by the use of the door
and the small leakage through 1t:
crevices. The ice chamber require:
no ventilation, hence economies the
ice to the best advantage, while the
water from the melting ice is turned tC
the best account by circulating around
the room in the waste pipe. Tho best
temperature for eggs and fruit is about
80 degrees or any temperature
below 40 degrees and above
freezing, where this kind of stock il
often changing by sale. II stock is tC
lie for considerable time. 81 degrees
should DO obtained if possible. Orange
