Zida zopangira manyowa a nkhosa
Manyowa a nkhosa amathanso kukonzedwa kukhala feteleza pogwiritsa ntchito zida zokokera.Kapangidwe ka granulation kumaphatikizapo kusakaniza manyowa a nkhosa ndi zinthu zina ndiyeno kuumba chisakanizocho kukhala ma pellets ang'onoang'ono kapena ma granules osavuta kugwira, kusunga, ndi kunyamula.
Pali mitundu ingapo ya zida za granulation zomwe zingagwiritsidwe ntchito popanga feteleza wa manyowa a nkhosa, kuphatikiza:
1.Rotary ng'oma granulator: Iyi ndi njira yotchuka yopangira ma pellets a feteleza a manyowa a nkhosa.Mchitidwewu umaphatikizapo kuwonjezera chomangira pa manyowa a nkhosa ndi zinthu zina zosakaniza ndi kugwetsa chisakanizocho mu ng'oma yozungulira.Kutentha kopangidwa ndi ng'oma kumathandiza kulimbitsa chisakanizocho kukhala ma pellets.
2.Disc granulator: Mtundu uwu wa granulator umagwiritsa ntchito chimbale chozungulira kuti chiphatikize manyowa a nkhosa ndi zinthu zina kukhala pellets.Chimbalecho chimakhala ndi masamba angapo opindika omwe amathandiza kusakaniza zosakaniza ndikuzipanga kukhala ma pellets ozungulira.
3.Pan granulator: Mofanana ndi granulator chimbale, poto granulator ntchito mozungulira poto kuti agglomerate nkhosa manyowa ndi zipangizo zina mu pellets.Chophikacho chimakhala ndi masamba angapo opindika omwe amathandiza kusakaniza zosakaniza ndikuzipanga kukhala ma pellets ozungulira.
4.Extrusion granulator: Mtundu uwu wa granulator umagwiritsa ntchito screw extruder kukakamiza manyowa a nkhosa ndi zipangizo zina kupyolera mu kufa kuti apange pellets.The extruder imagwiritsa ntchito kukakamiza kusakaniza, komwe kumathandiza kuti apange ma pellets.
5.Wodzigudubuza atolankhani granulator: Mtundu uwu wa granulator umagwiritsa ntchito zodzigudubuza ziwiri kuti zikanikize manyowa a nkhosa ndi zipangizo zina mu pellets.Kupanikizika kopangidwa ndi odzigudubuza kumathandiza kupanga chisakanizocho kukhala ma pellets.
Pambuyo pokonza manyowa a nkhosa kukhala ma pellets, amathanso kuyanika, kuziziritsa, kupaka, ndi zida zina kuti apange feteleza wapamwamba kwambiri.
