Kev tu noob yog thawj kauj ruam hauv kev ua cov noob.Vim muaj ntau yam impurities hauv cov noob, cov tshuab tsim nyog yuav tsum tau xaiv los ntxuav.Raws li cov khoom sib txawv, nws tuaj yeem muab faib ua cov impurities loj thiab me me impurities raws li qhov ntev geometric;Raws li qhov ntev, muaj cov impurities ntev thiab luv impurities;Raws li qhov hnyav, muaj lub teeb impurities thiab hnyav impurities.Txawm hais tias lawv yog lub teeb impurities, lawv tseem tuaj yeem muaj qhov sib txawv ntawm qhov hnyav thiab qhov ntom ntom (qhov tshwj xeeb lub ntiajteb txawj nqus).Cov xim sib txawv kuj yog ib hom kev faib cov noob impurity.
Cov khoom sib txawv ntawm impurities txais kev tshem tawm sib txawv.Cov txheej txheem tshem tawm sib txawv yuav tsum xav tau cov txheej txheem sib txawv.Cov hauv paus ntsiab lus hauv qab no feem ntau tau txais.(1) Yog tias cov impurities sib zog dua li cov noob ib txwm muaj, thiab qhov loj me yog pom tseeb txawv ntawm cov noob ib txwm, yuav tsum siv lub tshuab ntxuav kom huv.(2) Thaum tshem tawm cov impurities ntev lossis luv luv uas pom tseeb qhov sib txawv ntawm qhov ntev thiab qhov loj thiab tseem tsis tuaj yeem tshem tawm tom qab kev sib cais ntawm huab cua, lub qhov (socket-type indented separator) yuav tsum siv. Lub qhov (socket-type cleaning machine), qhov kev huv huv tau zoo dua qub, thiab qhov loj me me kuj zoo ib yam, tab sis tseem muaj qee cov txiv hmab txiv ntoo qhuav thiab worm-noj kernels tov nrog pob kws;Qhuav thiab shriveled nplej thiab shelled nplej nyob rau hauv hom qoob mog;Rau cov kab mob worm-noj thiab kab mob hauv cov taum, feem ntau ntawm cov impurities saum toj no yog qhov ntom ntom (qhov tshwj xeeb lub ntiajteb txawj nqus) impurities, uas zoo ib yam li cov noob zoo hauv qhov hnyav thiab nyuaj rau tshem tawm.Lub sijhawm no, lawv yuav tsum tau ntxuav nrog lub tshuab nqus tsev tshwj xeeb.
