Drying Methods Used
Ventilation
The ventilation sjstem was
quite similai to the one used in
the 1967-68 expeuments. How
ever, some veo significant
changes weie made
The size of the fans used foi
circulating air was incieased
An aluminum four bladed fan
with a 16 degree pitch, powered
with a totally enclosed 1 ., H P
single phase motor instead of *4
H.P. and dehvenng 4900 cubic
feet per minute, w as used. These
fans were located in positions
similar to the pievious expeu
ment.

The use of the more powerful
fans resulted in an average an
velocity of ovei 500 feci pci
minute in contiast to 250 feel
per minute However, electrical
consumption also was incteased

Stirring
Minor changes were made in

its efficiency.

By further drying the manure
after it was removed trom the
poultiy house with a commercial
diyer, the quantity of manure
remaining was reduced to 17,556
pounds with less than 10 per cent
moisture content. Combining the
actual drying costs for increase
in ventilation and the dryer, a
total of $66 58 was obtained This
calculated to a cost of $7 60 per

In the other 30 by 100 feet

When dneet field application
is planned, the fust diving stage
is all that is needed The manuie
can be icmoved on a continuous
automatic basis oi at intervals of
scvoial weeks
If both diying stages are de
sued in order to pioduce a di.v
manuie suitable for sale as an
oi game fertilize!, the two stages
can be integrated as a complete
automatic drying system
From these and earhei experi
ments it was noted that on the
average after the first stage of
drying inside the poultry house
the manure remaining amounted
to slightly less than half the
weight of feed consumed.
Thus, when chickens consume
1 ton of feed, approximately h'z
ton of relatively dry manuie
remains
After the second stage of dry
ing with the use of the commer
cial dryer, the weight was re
duced to about 30 per cent of
oiigmal weight of feed con
sumed. Hence, slightly over v <
ton of dry manure with less than
10% moistuie remains from each
ton of feed consumed by the
chickens
Capital Investment
The estimated capital require
ments for a flock of 25,000 layers
for a 40 x 400 feet house for
total ventilation with exhaust
fans and circulating fans over
manure run between 10 and 15
cents per bird
The stirring and cleaning
mechanism, including the power
unit, cable, reversing and re
cycling units and cioss elevator,
also runs about 10 to 15 cents
per bud
The commercial dryer adds
about 20 cents per bud to invest-

Benefits of Dehydration
1 The weight of manure to be
handled can be reduced to about
'a to 1 the onginal weight pro
duced The manuie is in a dry,
textured form that can be easily
handled, thus reducing handling
costs
2 Odors inside the house and
in the commercial drying pro
cess are practically eliminated.
Fiequent stirring of dioppmgs
and use of high velocity an not
only speeds drying but prevents
excessive growth of anaerobic
bacteria, the organisms which
manufacture the offensive odors.
Elimination of these odors at
the outset is essential if the final
dry product is to be free of
offensive odors
Only by having a dry product
fiee of obnoxius odors can it be
merchandised successfully.
Eliminating odors make pos
sible the use of the sloping wire
floor and its manure dehydration
system near urbanized areas
without causing a nuisance
3. Less “down-time” between
flocks is required since the ma
nuie is practically all removed
b> the time the flock is removed.
This is in contrast to systems
where manuie is permitted to
accumulate over the life ot the
flock.
4 Labor requirements for
cleaning are sharply reduced.
5 Fly breeding areas are con
stantly being destroyed thus
keeping flies under control
6 Capital investment require
ments aie relatively low.
