ratio of the weight of corn kernels blown by the sheller fan, to the weight of the total corn
kernel input of the sheller, expressed in percent
blower loss
type of shelling cylinder formed by a rolled metal sheet/plate or formed by
longitudinal bars adjacently arranged forming a continuous cylinder
closed-frame cylinder
iron grill frame partially or fully surrounding the cylinder on which the shelling elements
rubs, shear and/or impact the corn ear with or without husk
concave component
part of the ear corn where the kernels are attached
corn cob
pistillate inflorescence of the plant Zea mays L., enclosed with a leaf-like protective covering
known as husk
corn ear
machine used to remove the husk of corn ear, detach, separate and clean the corn kernels
from the cobs in one operation
corn husker-sheller
machine used to detach, separate and clean the corn kernels from the cobs
corn sheller
type of shelling unit consisting of a cylinder with shelling elements such as knife bar or
pegtooth
cylinder-type
kernels which show signs of fissures or fractures or splinters
cracked kernels
type of shelling unit consisting of a vertical disc with spiked surface
disc type
dehusked corn
corn-in-cob
unshelled fruit of the corn plant where the husk has been removed mechanically or manually
ear corn
type of corn sheller wherein the ear corn are fed into shelling chamber by gravity
hopper-fed type
dry and indehiscent seed developed from the ovary of the ear corn
kernel
ratio of the weight of the corn kernel present in the ear corn to the weight of the ear corn
kernel-ear corn ratio
kernels that were broken and/or scratched as a result of shelling operation
mechanically damaged kernels
amount of moisture in the kernel expressed as percentage of the total weight of the sample,
wet basis
moisture content
difference between the percent cracked sample taken before and after the shelling operation
net cracked kernel
type of shelling cylinder where the shelling elements are attached to the equally spaced
longitudinal bars arranged cylindrically
open-frame cylinder
ratio of the weight of clean corn kernels, to the total weight of unclean corn kernels sample,
expressed in percent
purity
ratio of the weight of corn kernels that fell out from the machine during shelling operation to
the weight of the total corn kernel input of the sheller, expressed in percent
scattering loss
ratio of the weight of corn kernels that come out of the shelling chamber with the cobs at the
cob outlet, to the weight of the total corn kernel input of the sheller, expressed in percent
separation loss
whole and damaged corn kernels separated from the cob after shelling
shelled kernels
shelling drum
part of the shelling unit that rotates about an axis and it is equipped with pegs on its periphery
shelling cylinder
ratio of the weight of the shelled corn kernels collected at all outlets, to the total corn kernel
input of the sheller, expressed in percent
shelling efficiency
ratio of the weight of the shelled corn kernels collected at the main outlet, to the total weight
of the corn kernel input of the sheller, expressed in percent
shelling recovery
shelling chamber
part of the sheller where the kernels are detached and separated from the corn cobs
shelling unit
type of corn sheller wherein the ear corn are fed into shelling chamber with the application of
external force
table-fed type
kernels that remain in the cob after shelling
unshelled kernels
ratio of the weight of corn kernels that remained in the cobs of the corn fed into the shelling
chamber, to the weight of the total corn kernel input of the sheller, expressed in percent
unshelled loss
unbroken kernels after shelling
whole kernels
