water.
The liquid ammonia is then pumped
through coils Of pipe that come in con-
tact with the water to be frozen. The
ammonia absorbs the heat from the
water, and when the ammonia has
drawn from the water all Of its heat
and reduced the temperature to its own
level the water congeals into ice.
The arrangement Of the pipes in an
Ice factory is ingenious. It would be
impracticable to make ice in huge
blocks and to cut It up afterward, so
in most factories the pipes are SO ar
ranged that small tanks containing
water may be set into pits. These
tanks turn out q block Of ice that
weighs 200 pounds and thus aid greatly
IN the convenience Of handling them.
In some factories the blocks are made
larger and are then called plates. Some
times these plates are made as large
as twelve feet long and from six to
eight feet wide and a foot in thickness,
having the appearance of plate glass.
Unlike the natural ice, the artificial
product is always clear. That is be-
cause 1t has been found that in order
to make the water freeze readily it is
necessary to remove from it as much Of
the air as possible. To get out the air
the water has to be distilled, and in
this process the water is also purified
to a considerable extent.
In the making - artificial fee by the
tank system Cne J. the early tro'-bles
was that the ice took on q frosty ap-
pearanCe. This was due to air, but 1t
has been largely overcome by the use
of a specially constructed nozzle for the
pipe line that fills the empty tanks,
1t requires from forty-eight to sixty
hours to freeez a 200-pOund tank, so
that a factory to turn out 200 tons Of
ice a day has to have from 1900 to
1000 tanks, necessitating considerable
floor space and investment.
When the tanks have been sufficient
ly frozen they are lifted out and run to
the bumper" This is a Continuance
that throws the tank on end and per-
mits hundreds Of little streams OF warm
water to play on the four sides Of the
iron. loosenhlg the grip Of ice until it
drops out, perfect cake.
In all times or during the winter
when the demand for ice is light, the
factory begins working on stock. The
blocks Of ice made are sent into a stOr-
age room and packed away. one on top
of the other, but between each layer
are thin strips of wood. In the oTdi-
nary icehouses sawdust or straw is
tory this Is not necessary, for the tenn
perature Of the room is maintained by
refrigeration.
The LIQUID ammonia Is pumped
through a series Of pipes IN the room
and the heat from the air Is absorbed
in Just the same manner as the heat is
absorbed from the water. This Is mere
ly the method Of refrigerating that is
generally employed and for which new
uses are being found daily. No longer
do dealers in perishable foods alone de-
pend upon refrigeration, but depart
ment stores are installing the system In
rooms in which are stored during the
summer months valuable furs, blankets
and wooden goods.
The making of ice and refrigeration
have caused an increase in the ammo
MIA producing industry and there have
been great strides in this industry with
in the past few years. The ammonia,
in huge steel drums, is easily trans
ported and thus it is now possible to
have ice factories in even tropical coun-
tries.
There are many interesting stories
told Of methods used IN the introduction
Of fee IN the tropics where the most
Of the natives never even heard of II.
It Is said that when a plant in a South
America was opened and the natives
bought the beautiful crystal blocks TO
carry them into the interior they were
astonished at the lightness OF their bur-
den when they reached their destina-
ton The hot sun had reduced the ice
TO water and much wrought up were
they for they were under the impress
sion that the blocks would last for
years and continue to give off their
most OfeaSing GOODNESS.
Then. too, the enterprising Yankees
were met by the equally "enterprising"
officials who taxed" the fcemakers IN
til all Of the profit disappeared and
finally the plants were abandoned.
This was just to the liking II the ma
tives, who promptly began 20 run out
fits for their own profit.
While many persons are under the
impression that an fee factory must be
a delightfully."- cool place to work, a visit
to one viii demonstrate that for heat
such a place can scarcely be equalled.
On the principle that all heat ascends
the ice-makng apparatus is below
where one walks, consequently on the
top of the floor all the heat Of the build
ing is concentrated.
A 200-pound cake Of fee is pretty, but
there Is little poetry in the handling Of
one and those who sling these blocks
about perspire freely. It is remarkable
how dexterOps the icemen become in
the handling Of fee. Unconsciously they
apply natural laws Of physics and swing
the huge cakes on their shoulders with
apparent ease.
Then, too, in the cutting Of ice the
men display their skill. To split a
cake a man taps It gently several times
with his tomahawk-Iike pick and II
breaks true. In estimating how much
of a piece Of fee it will require to make
up a given weight many experts IN Ice
houses can chop off a piece that will
weigh within an ounce.
One Of the features Of the annual
convention Of ice dealers is the conpe-
tition IN handling ice. This consists Of
carrying 200-pound blocks by means Of
a pair of tongs, splitting a block into
from five to ten pieces and each piece
to weigh the same and in tossing small
pieces to a teammate who catches them
with tOngs.
The rivalry among the icemen is keen
and not infrequently a dealer will bring
his most expert handler to compete
with some man that another dealer has
brought for the purpose, thus introduce
ing a little fun into what IS ordinarily
rather prosaic occupation entailing
little but hard work.
