Blower loss
Machine used to detach and separate the paddy from the panicles
Mechanical Rice Thresher
Ratio of the weight of grains that fell out from the machine during threshing operation, to the weight of the total grain input of the thresher, expressed in percent
Scattering loss
Ratio of the weight of grains that come out of the threshing chamber with the straw, to the weight of total grain input of the thresher, expressed in
percent
Separation loss
Grains that are detached from the panicles by the thresher inclusive of mature, immature, and damaged grains
Threshed grain
Part of the thresher where the grains are detached and separated from the panicles
Threshing unit or Threshing chamber
Part of the threshing unit that rotates about an axis and it is equipped with either pegs, rasp bars, or wire loops on its periphery
Threshing cylinder or Threshing drum
Ratio of the weight of grains that remained in the panicles of the plants fed into the threshing chamber, to the weight of total grain input of the thresher, expressed in percent
Unthreshed loss
Threshed grain with 100% purity exclusive of the empty grains and other impurities
Clean Threshed Grain
An electric motor, or a gasoline or diesel fed engine used to run the thresher
Primemover
Preliminary operation of the machine to make various adjustments prior to the conduct of test
Running-in period
The weight of the threshed grains collected at the grain outlet
Threshing output
Grains obtained after the removal of hull, bran and germ
Milled rice
White rice
Device of a rice mill, which removes the remaining bran on the milled rice and produces a glossy appearance
Polisher
Outer most rough covering of the paddy grain (palea and lemma) consisting of the empty glumes, floral glumes, and awn
Rice hull or Rice husk
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
Auxiliary device used to separate stones from the paddy and/or brown rice.
Destoner
Rice grain from which the hull, the germ, and the bran layers have been completely removed (0%)
Overmilled rice
Component of a rice mill that removes the bran in the brown rice.
Whitener
Auxiliary device used to remove foreign matter/impurities from the paddy before milling
