Makina oyeretsera madzi ndi makina omwe amagwiritsa ntchito mphamvu ya centrifugal kulekanitsa zigawo kuchokera ku tinthu tamadzimadzi ndi tolimba kapena chisakanizo cha madzi ndi madzi. Ma centrifuge amagwiritsidwa ntchito makamaka kulekanitsa tinthu tamadzimadzi ndi madzi omwe ali mu suspension; kapena kulekanitsa madzi awiri osasakanikirana amitundu yosiyanasiyana mu emulsions (monga kulekanitsa kirimu ndi mkaka); ingagwiritsidwenso ntchito kuchotsa Madzi mu zinthu zolimba zonyowa, monga kuumitsa zovala zonyowa ndi makina ochapira; olekanitsa machubu apadera a ultra-speed amathanso kulekanitsa zosakaniza za mpweya zamitundu yosiyanasiyana; pogwiritsa ntchito mawonekedwe a kuchulukana kosiyana kapena kukula kwa tinthu tamadzimadzi tolimba mu zakumwa zomwe zili ndi liwiro losiyana la sedimentation, zina zoyeretsera madzi. Ma Centrifuge amathanso kugawa tinthu tamadzimadzi ndi kuchuluka kapena kukula kwa tinthu tamadzimadzi.

Mota yaikulu imayendetsa pulley ya lamba kuti ipereke mphamvu ku ng'oma kudzera mu lamba wa triangle, zomwe zimapangitsa ng'oma kuzungulira mozungulira mozungulira mozungulira ndi kupanga mphamvu ya centrifugal. Pa liwiro lodyetsa, zinthuzo zimalowa mu ng'oma kudzera mu chitoliro chodyetsa ndipo zimagawidwa mofanana pakhoma la ng'oma. Chakudya chikafika pa voliyumu, wolamulira wa level amachitapo kanthu kuti ayimitse chakudyacho. Mpaka kulekanitsidwa kwa liwiro lalikulu. Pansi pa mphamvu ya centrifugal, zinthu zolimba zomwe zili muzinthuzo zimapita kukhoma la ng'oma ndipo pamapeto pake zimakhala pansi. Gawo lamadzimadzi likafotokozedwa bwino kuti likwaniritse zofunikira, liwiro la ng'oma limachepa kufika pa liwiro la skimmer ndipo madzi oyeretsedwa amachotsedwa mu makina kudzera mu payipi yotulutsira madzi. Chinthu cholimba chimagwidwa mkati mwa ng'oma ndikupanga keke yosefera. Pomaliza, ng'oma imatsika kufika pa liwiro lotsitsa (30-100r/min), chosefera chimayamba kukanda, keke yosefera imakanda pansi, gawo lolimba limatulutsidwa kudzera pa doko lotulutsira pansi pa centrifuge, chosefera chimakwera kubwerera pamalo oyamba, ndipo njira yozungulira imatsirizidwa.

Chiwonetsero cha National Pharmaceutical Machinery Expo ndi China International Pharmaceutical Machinery Expo chomwe chinachitika nthawi yomweyo chinayamba kuchitika m'ma 1990, ndipo chimachitika nthawi iliyonse ya masika ndi nthawi yophukira. Kuyambira mu 2004, chakhala chikulembedwa ngati chimodzi mwa ziwonetsero zazikulu zomwe zimathandizidwa ndi Unduna wa Zamalonda wa People's Republic of China mosalekeza. Kuyambira mu 2008, chavomerezedwa kukhala Chiwonetsero cha International Pharmaceutical Machinery Expo ndi Unduna wa Zamalonda. Ziwonetserozi zikuphatikiza mankhwala akumadzulo, mankhwala achikhalidwe aku China, mankhwala a biopharmaceutical, mankhwala azinyama, mankhwala ophera tizilombo, zinthu zina zaumoyo ndi mankhwala a tsiku ndi tsiku, makampani opanga chakudya amafunikira zida zosiyanasiyana zopangira, kukonza, kuyesa ndi zida zina zothandizira. Chimavomerezedwa ndi makampaniwa ngati chiwonetsero chaukadaulo, chapadziko lonse lapansi, chachikulu, omvera ambiri, komanso malonda okhazikika, kukambirana mu imodzi mwa nsanja yosinthira zida zamankhwala.
