Palibe Chokhalira Kwa Inu!
Coffee hulling ndi njira yomwe mungasankhe pakuphika khofi. Kafukufuku wa khofi amapezeka pakapita nthawi yopanga khofi; Kawirikawiri imachitika pakati pa mphero ndi kupota, ngakhale kuti anthu ena amaganiza kuti ndi gawo la mphero kapena kudumphira ndikusunthira payekha ndikuyeretsa.
Cholinga cha khofi kumatulutsa khungu (lomwe limatchedwanso "pergamino") kuchokera ku nyemba za khofi.
Chikopacho ndi chinthu chachilengedwe chomwe chimapanga nyemba za khofi, monga endocarp (chingwe chofanana ndi chingwe) chomwe chikuzungulira mitundu yambiri yambewu (monga mbuto za apulo). Kuchotsa chikopacho ndizosankha chifukwa nyemba zina za khofi zimagulitsidwa "mu zikopa" (kapena "en pergamino").
Pambuyo pa nyemba za khofi zakhala zouma (mwina dzuwa ndi / kapena makina oyanika), khungu la zikopa ndilophwa ndi louma, kotero likhoza kuchotsedwa mosavuta. Pankhani ya chonyowa khofi, kubisala kumachotsa nthongo zouma pafupi ndi nyemba za khofi (kuphatikizapo exocarp, mesocarp ndi endocarp / zikopa). Kwa khofi yowuma bwino, khola limachotsa mankhusu komanso zouma mucilage ku nyemba. Kwa khofi yowuma (onani ndondomeko ili m'munsiyi), kukunkha kumachotsa chikopa cha chikopa cha nyemba za khofi, zomwe zimaphatikizapo mankhusu ndi mucilage komanso zinthu zina. Mosasamala kuti zingati zingati zikuchotsedwa panthawi yopuma, zonsezi zimasamalidwa mu sitepe imodzi.
Mayendedwe amagwira ntchito monga chonchi. Makina otchedwa "huller" amagwiritsidwa ntchito kuchotsa zikopa za khofi. Nkhosa zimachokera ku miyala yamphongo yosavuta kupita ku makina apamwamba omwe amachoka pa khofi kuti achotse zikhomozo. Ziribe kanthu kaya ndi zophweka kapena zovuta motani, ntchito yaikulu ndikuti amachotsa chipikacho mpaka icho chikugwedezeka kutali.
Voil à ! Zosakaniza nyemba za khofi.
Zindikirani: Mu njira yowumitsa yowuma, zoumba zouma zamasamba zimasungidwa mochuluka mu silos wapadera mpaka zitumizidwa ku mphero komwe kumakhotakhota, kukonza, kuyika ndi kunyamula. Mu njira zina zogwiritsira ntchito, kuomba kumachitika popanda kuyembekezera pakati.
