MOISTURE (ONTEXNT AND SIIRINIKA(GE IN GRAIN.


REDUCTION OF MOISTURE AND SHRINKAGE.

livingg (i1e co()nsideration 1 to the loss of material resulting from the
handling of grain through an elevator, (drier. etc., the re(luction in
thle percentage of moisture is inot the same as the percentage loss in
weight, alllnd sllouild not be the same if thle moisture content is properly
determined anid thlie weighing d(lone correctly, notwithstanding the
fact that water is thlie only substance liberated in tlie drying process.

WIlY TIHE REDUCTION OF MOISTURE AND THIE SHRINKAGE IN GRAIN
ARE NOT THE SAME.
Tle difflerenice between tile reduction in thlie percentage of moisture
and thlie shrinkage exists be('ause there is a constant change of base
in making the moisture test. Moisture percentages are calculated on
the basis of tlie wet sample, i. e., 100 grams of grain containing 20
per cent of moisture co()nsist of SO grams of dry material and 20 grams
of free water. For thlie purpose of dlemlonstration it is assumed that
thls 100 graiis of grain containing 20 per cenlit of moisture be dried
until tlie weight is reduced to 90 grams. The weight has therefore
been reduced 10 per cent. During the drying, 10 grams, or one-hia,4
of the water, have been liberated and( likewise 10 grams still remain in
the grain, but thlie remaining 10) grams of water are contained in thlie
partially dried grain, which weiglis only 90 grams, i. e., tein-ninetiethlis,
or (me-ninthi of thlie partially dried grain is water. This fraction
expressed in percentage is equivalent to 11.1 per cent, which is the
moisture content of tile riii,i inij-ii 90 grams of grain. In actual prac-
tice thlie moisture content after drying would not be determined on the
90( grams alone, but a new sample of 100 grams, tlie same weighlit as
was used for thlie original test, would lbe taken anid this would contain
11.1 grams, equivalent to 11.1 per cent, ofw"ater.
II the illustration here given I hliere hlas been a reduction in weight
from 100 grams to 90 grmis, (or a shrinkage of 10 per cent. Tlie
moisture content of thlie gr:iin hlias been lowered from 20 per cent
before dlr\ ir to 11.1 Iper cenlt after Irving, or a reduction of only 8.9
per cent. The shrinkage in weighlit therefore exceeds tlie re(luction
in moisture b)V 1.1 per cent. This (lierenice, however, is not constant
)but depel)en(Is on thle (luantity of water oriiin,.lly contained ill tihe
graini anid tlie extent to which thie dr viig is carried. Moreover, the
difference increases irregularly litil thlie moisture conitenlit is reduced(l
approx ) imately one-lhall, after wi ich it gradually (decreases and wIhen
tlie free water is eltirelv expelled tlie difference between t lie slirinkage
in weight anld the redluictioi in miioisture cointenlit equ(als zero.
These variations are better slhow\n ii Table 1, in which the i.il
moisture co('ntenit is taken as 25 per ceint. The first part of thlie table

MOISTURE CONTENT AND SHRINKAGE IN GRAIN.


lo express tlhe -lj'i .ieo in terms of bushels or pounds thile calcula-
ti(ln 1mav be made a's in tle followii .g example:
I'roblit .-What. will be tih' shrinkage in weight oiln l.O(tt) bushels of corn if tlhe
moist'lre content is reduced from 2.5) ptr cent It 1,7) per cent?
I t-vry matter after .li ;i,_ =- 100 15 = ,s:5 pe1r cent.
Dry matter Ibefo r drying 1110 25 7-5 per cent.
Original weight of corn 1,000 bushel.
Therefore 8) per cent : 7. per cen :: 1,000 bushels : final weight.
(Coilmpleting the lpr(o](rlio n 1 muniltiplying 1,0()0 ) by 7.3 and divid-
in- tlie p(Irduct by S5 the fiiinIl weight is fomind to be 8S2.4 bhi-li]-.
givin g a shriniikage equivalent to 117.6 bushiels, or 11.76 per cent.
The shrinkage in this case exceeds the redtci ion inii moist re content
byV 1.76 per cent.
For additional data see tables IT and III.
Moistr.'I. -To lind thle fill moisture (olitenlit of all- given hlt of
grain or other substance which lias been dried, the moisture c,(lntentt
before di 'it I1 ad the weight before and after drying being known,
the following simple proportion may be used:
Weight fOriginal Percentag'e of dry matter
after drying J I weight J I in original
r = percentage of dIry matter after drying.
Therefore 100 less .x equals the per(entag( of moist ure remaining after driving.
Tlie following will serve as ian (exampl)le:
]'rohhlm.-If 1,000 bulshels of grain containiing 2 pe)r cent of moisture ae r(, educed
to, 9100 bush'els on dryingl, what, will be the . i ii _. of moisture' inll thle dried grain?
900 lbushel- : 1,000 bushels :: 7.') per cent :.r.
Complete( i2 thlie iproportion lbv multipl)ying 75 by 1,00() an(l diviliii_
(lie product by 9()(), the value of x is found to be S3.33 per cent, which
is lie pr)(ce(ntage of (dry matter re(maininiiti after drying. Therefore
10)0 per cent less ,::.-3 per cent equals 16.67 per cenit, which is thlie
moisture content of thle dried grain.
Th'e , redticed to I(;.(;7 pe)(r cent, or I (decre(ase( in moisture co(lntent ofS ;.
per ce]nt as th(e result of drying. At the same time the wighit was
reduced from 1,()()0 bushels to 900 bushels, or a hl,,iiii'..w-v of 10 per
ce',nt. Thle shrinkage in t,.iht, (herefore, exceeded llte reduction in
almost ur(' ) v 1.67 per cei('('lt.
'For aIdditioml data ])trl;!,ii,-_ to moisture see Tables TIT and IV.
