IMPORTANT FEATURES OP J DING
R ICE .. .....
THE SAMPLING OPFO *' ;
The obtaining of a representative satiple is
essential to the determination of .the. ti grade
of a given lot of rice. If the sample oi."lai d-
is not representative no amount of 4 iiifiak-
ing determinations for the :grading fator will
establish. the true grade of the rie..e 4apled.;
Consequently, great care should be t-k-' in
sampling in order that the sample: on whn the
grade of the rice is to be based shall tl re: "r
present the rice sampled.
The sample should be approxin.atel. arts
in size. If the time to elapse between irth w -r-
ing of the sample. and the determinatio f 'aiide
would permit of such change in the jjoAion
of the sample as to affect the grade. at l ast
1 pints should be inclosed in ta air i6-tbCon- .
trainer and the remainder, if any, in "4*-N ''
cloth sack. '
In case of rice in sacks, samples shalte:e d'wn-
from as many individual sabks seletead .t;ran-
; :: :..N ..1
dom as will enable the sanhpler to p. rq an
average and representative sample of 'the :ie 5tir
lot. In case a lot is' of such size or is sta- d in
such a manner that a representative an.
not be obtained, no official inspection ?a tt rice 4.
should be made until a representative o;pn f

BULK RICE TRIER (PROBE) AND' :.J iNG
CANVAS ': :
: : :.' *. : ...
For obtaining a representative sample from a
carload of bulk rice the use of the double tube,
separate compartment grain trier "(prboe) shown
in Figure 2 is recommended.
The use of such a, trier makes it ..po ifoefor
the sampler to note any uneveuiness I' ing
and to ascertain the, approximate o o n and
quantity of any mixture of rice or of d.itj heat-
ing, or damp spots, etc., found tf ny 'art of the
rice. To assist in doing this it is advisable to
use a canvas 5 by 2 feet in dime'sionst:: ... ... lch
to empty, the grain from the tier. T' grain
should be emptied lengthwise oA their SAnvas,
each separate trierful. apart from thhe- 6'tt, so
that the grain. from leach comprtmentin be
noted separately. ;

SAMPLE DIVIDER (BOERNER SAMrPLR)
After a representative sample bf t i' Llo or
parcel of; rice to be graded is ; obt&* id i, it is
usually necessary to reduce its sized consia bly,
in order that the grade maS be deterni"ld by
careful analysis. To.reduce these df a' ple
of rice containing broken kernel s&or fa sub-
stances of different specific gravity o tfe than
of the rice with which. they are mixed, andl the
same time obtain a sample as repres tative as
the original, is hardly possible except b. w han-
ical means.
