Approach OF warm weather adds to
the dairyman's problem Of keeping
milk from souring. 1t is commonly
known that bacteria in milk produces
changes which spoil 1t and therefore
every means should be taken to reduce
the bacteria content of milk as much
as possible. This can be done, first, by
producing milk under clean conditions;
second by cleanliness in handling and
keeping it In sterilized utensils, and
third, by cooling 1t and keeping 1t cold.
Dirty milk utensils, and even those
which apparently are clean but which
have not been sterilized, contain vast
numbers OF bacteria which are added
to milk or cream when it comes in con-
tact with them. 1t is true that even
when milk is produced under clean
conditions it will contain few bacter-
la, for when such milk is placed In I'M
stcrilized utensils or Is run through |
an unsterilized strainer cloth of the
separator, large numbers of bacteria
are added, which are apt to spoil 1T
quickly. When dairy utensils are steri-
lized by steam germs are destroyed,
and therefore milk and cream in these
utensils will keep sweet much longer.
Sterilization of utensils on farms Is
neither difficult nor expensive ii the
simple steam sterilizer designed by
dairy specialists OF the United States
department OF agriculture Is used.
Scr Smaller or Larger Farms.
This sterilizer is designed to be of
greatest use to those who have one,
two or three ten-gallon or smaller cans
with similar number Of pals and a
strainer cloth, but 1t can be used to
advantage where a larger number of
cans are required. In its construction
are needed first roasting pan Of stan
dard size GO inches long, IA inches
wide and inches deep, close fitting
insulated cover to fit over this pan,
and box with removable top to fit
over the cover.
To make the cover, take a sheet OF
heavy galvanized iron and cut 1t large
enough to allow it to project three
fourths OF an inch over the edge OF
the pan. Bend the edges of the sheet
so as to form shallow box with sides
three-eighths of an inch high. Then
cut out a cover for the shallow box
thus made. Cut hole one and one
half inches In diameter in the center
braces should be placed crosswise on
the box to strengthen 1t. Then fill
the shallow box with paper or asbes-
| tos sheets, after which the top of the
| box is carefully soldered on. Solder
round, galvanized-iron pipe four and
one-half INCHES long and one and one
half inches in diameter in the hole In
the center Of the cover.
The box with the removable cover
previously referred to should also be
made of galvanized iron. This box
should be II inches high and large
enough to fit on the cover just de-
scribed. The complete cost of THU
outfit should not be more than So, and
If soldering outfit is available it car
the job.
Using the SteriIlzer.
To sterIlize cans, the roasting par
should be placed on two burners of {
cook stove or an especially built bricl
furnace. The pan should be filled
with water to the depth of one incl
and the cover placed over it. AS sool
az the water heats sufficiently, steam
will come out Of the outlet pipe, ant
as rule 1t takes less than Is minute
to develop enough steam for sterillza
ton. When steam Of sufficient heat Ca
least POS degrees Fahrenheit) has bee
reached, place the can over the stear
|, outlet for FIVE minutes, then remove
shake out any water and place Ut
right on the floor. The can should b
absolutely dry In two or three minute.
If not dry In that time 1t shows tina
the steam was not as hot as 205 d.
grees Fahrenheit, or that the can ha
not been washed clean.
Pals and other utensils are ster
lized in the same manner. But
sterilize can covers, strainer cloth
, separator parts and other small utel
, 4 sils 1t is necessary to use the box ha'
; ing the removable cover. When ii
steam begins to Issue from the outl'
pipe place the box over the sterilize
put the small utensils in 1t and plat
the cover over the box. See that a
parts fit snugly so the steam will n
escape, and then proceed as in stel
lizing cans.
When properly operated, this stel
lizer destroys practically all bacter
In the utensils, including all disea
germs. 1t will accomplish the san
results as any sterilizer in viii
steam not under pressure is used. +
