PAES 206:2015 Flashcards
outer layer of the brown rice consisting of the aleurone cells covering the endosperm of the
rice grain
Bran
pieces of grains smaller than three-fourths (3/4) of the average length of the unbroken kernels
Broken grains
dehulled rice
cargo rice
dehusked rice
rice kernels from which only the hull has been removed and with the bran layer still intact
brown rice
ratio of the dehulled grains to the total amount of grain input, expressed in percent
coefficient of hulling
ratio of the whole brown rice to the total amount of dehulled grains, expressed in percent
coefficient of wholeness
grain or a piece of a grain with its length equal to or greater than three-fourths (3/4) of the
average length of the whole kernels
head rice
husker
dehuller
component of a rice mill that removes the hulls (palea and lemma) from the grains
huller
product of the coefficient of hulling and the coefficient of wholeness of grains, expressed in
percent
hulling efficiency
weight of paddy per unit loading time into the huller, expressed in metric tons per hour
input capacity
white rice
grains obtained after the removal of hull, bran and germ
milled rice
quantity of paddy that the rice mill can process to a specified quality per total milling
time,expressed in metric tons per hour
milling capacity
extent or degree by which the bran layer of the brown rice is removed as a result of whitening
milling degree
ratio of the weight of milled rice to the total weight of paddy, expressed in percent
milling recovery
ratio of the milling recovery obtained in actual testing, to the milling recovery obtained from
the laboratory test mill
milling recovery index
rice mill that employs a series of two or more whitening/polishing machines
multi-pass rice mill
rough rice
“palay”
unhulled grain of Oryza sativa, which means, grain with the glumes enclosing the kernel
paddy
ratio of the weight of grains with a size ofthree-fourths (3/4) or more of the whole grain to the
total weight of milled rice, expressed in percent
percent head rice
ratio of the percent head rice obtained in actual testing, to the percent head rice obtained from
the laboratory test mill
percent head rice index
device of a rice mill, which removes the remaining bran on the milled rice and produces a
glossy appearance
polisher
rice husk
outer most rough covering of the paddy grain (palea and lemma) consisting of the empty
glumes, floral glumes, and awn
rice hull
machine used to remove the hull and bran of the paddy to produce milled rice and consists
mainly of hulling and whitening assembly
rice mill
type of rice mill having an under-runner stone disc huller and vertical cone whitener (Figure
1)
cone “cono” type
type of rice mill using rubber roll huller and utilizes friction and/or combination of other
types of whitener
rubber roll type
type of a huller with rotating blades and utilizes pressure such as Coriolis’ force, frictional
force from the blades, or impact force at collision with the blades and the peripheral surface
centrifugal type
rice mill that employs only one whitening machine
single-pass rice mill
rice grain from which the hull, the germ, the outer bran layers, and the greater part of the
inner bran layer have been removed, but part of the lengthwise streaks of the bran layers may
still be present on less than 20% of the sample grains
well-milled rice
component of a rice mill that removes the bran in the brown rice
whitener
type of whitening machine consisting of a cylinder or cone coated with abrasive material such
as emery stone or any similar materials enclosed in a perforated steel housing
abrasive type
type of whitening machine consisting of a ridged cylinder enclosed in a perforated steel
housing
friction type
