POWDER MIL K
New Process for
Milk.
Treating
A MASON CITY INSTITUTION
Powe. Made in New and Economical
Way.

The building Is OF peculiar shape,
having more the appearance of a.
round grain elevator than milk fac
tory. It has tower Is feet high.
with the top Is feet about three feet
greater in diameter than the balance
which is 25 feet.
To start with. the milk must be
absolutely pure and clean. the know
ledge Of which will go long way
with the consuming public in the use
of the product. The milk is received,
tested and paid for much the same as
lis the milk in any creamery or cheese
factory: but here all similarity Of
treatment ends.
1t is pumped to the top of this Is
foot tower and forced into it in a
spray or vapor. This tower is lined
with galvanized iron and is heated to
about 1876 deg. F. The water in the
vapor is here condensed and runs off
while the solid. consisting of curd.
caselne and butter fats. fall to the
bottom in the powdered form.
The process is very rapid, requiring
less than FIVE minutes from the time
the milk starts on its journey to the
top Of the tower until the solids in it
reach the bottom in remarkable
form: and during this time the milk
is both pasteurized and aerated.
Eggs are to be treated in the same
way and both products. in this con-
densed form. will be shipped to the
large bakeries. candy factories and
in fact. into every channel where
they now are used and at cost in
transportation charges of nearly 80
per cent than in the original state.
The power to run this plant is GER
tainly a wonderful combination of
mechanical construction in which
economy of operation Is the main
point in view ;and when it is realized
that the 20 horse power gas engine
can run to its full capacity for ten
hours on 200 pounds of coal it will be
seen that the acme of producing pow
er at low cost has been reached.
A. Wooley suction gas producer
and producer gas plant has been in
stalled in an addition to the main
tower shaped building and it is just
what its name implies. A 20 horse
power gas engine does the great part
of the work of producing its own fuel.
,yhe Wooley gas producer is an ar
rangements of upright boilers and
tubes connected. each of which has a
part to perform along with the engine
in converting fuel. The Wooley gas
producer is an arrangement of upright
boilers and tubes connected, each OF
which has part to perform long with
the engine in converting fuel. steam
and air into gas, the fuel being
burned at slow incandescent heat.
through which air and steam passes
which by special arrangement. has
been previously superheated. The
resultant product is gas rich in carbon
and when mixed with air is highly in.
hammable and combustible.
Not alone Is the economy OF tue
one of the main objects obtained: but
the ease of operation is another feat
ure. The addition of fuel once il
three hours constitutes the work o.
firing this plant. This with keeping
the machinery oiled is all the worl
the engineer has to do. The system
is one that should commend itself t,
some of our larger creamery plants
whose fuel bills now represent tn,
largest item in their expense account
This whole plant is radical depart
ure from any of the present method
of handling milk in the dairy section
of the west and when we consider tn
wonderfully low cost of operation. tn
