Kuwumitsa kozizira, komwe kumadziwikanso kuti kuuma kowuma, ndi njira yomwe imachotsa chinyezi kuchokera kuzinthu kudzera mu sublimation, zomwe zimapangitsa kuti pakhale chinthu chowuma.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza mankhwala, kukonza chakudya ndi ma laboratories ofufuza.Mfundo ya luso lochititsa chidwi limeneli lagona pa kuzizira chinthu kenako n’kuika vacuum kuchotsa mamolekyu a madzi oundanawo popanda kuwasungunula kukhala madzi.

Kuwumitsa kozizira kumaphatikizapo magawo atatu akuluakulu: kuzizira, kuyanika koyamba ndi kuyanika kwachiwiri.Panthawi yoziziritsa, zinthuzo zimazizidwa kaye mpaka kutentha pang'ono, nthawi zambiri pansi pa kuzizira kwake.Izi zimatheka mwa kuyika zinthuzo mu chipinda chowumitsa ndi kuyika firiji kuti apange malo olamulidwa.Chinthucho chikaundana, chimatha kupita ku sitepe yotsatira.

Kuyanika koyambirira ndi gawo lofunikira pakuwumitsa kuzizira.Iyi ndi njira ya sublimation, momwe mamolekyu amadzi oundana amapita molunjika kuchokera kumalo olimba kupita ku gasi popanda kudutsa gawo lamadzimadzi.Izi zimatheka pogwiritsa ntchito vacuum kuchipinda chowumira, kuchepetsa kuthamanga ndi kutulutsa mamolekyu amadzi.Kusunga kutentha pang'ono panthawiyi kumapangitsa kuti mankhwalawa asawonongeke kapena awonongeke.

Gawo lomaliza, kuyanika kwachiwiri, ndikofunikira kuchotsa mamolekyu aliwonse omangika amadzi omwe sanachotsedwe poyambira kuyanika.Zimatheka ndi kuonjezera pang'ono kutentha mkati mwa chipinda chowumitsira madzi, zomwe zimapangitsa kuti mamolekyu otsala a madzi asungunuke.Izi zimatsimikiziranso kukhazikika kwanthawi yayitali komanso mtundu wa zouma zouma.

Mfundo yowumitsa kuzizira imachokera pa lingaliro la kusunga mapangidwe oyambirira ndi katundu wa chinthu.Mosiyana ndi njira zina zowumitsa monga kuyanika mpweya kapena kupopera mbewu mankhwalawa, kuumitsa kozizira kumachepetsa kuwonongeka komwe kumachitika chifukwa cha kutentha kwambiri komanso kusintha kwamphamvu.Mwa kuzizira zinthuzo ndikuchotsa madzi kudzera mu sublimation, kukhulupirika kwa mankhwalawo komanso zakudya zake, kukoma ndi fungo lake zimasungidwa.

Kugwiritsa ntchito ukadaulo wowumitsa-kuzizira kukukulirakulira kumafakitale osiyanasiyana.M'munda wamankhwala, amagwiritsidwa ntchito kwambiri kusunga zida zamoyo, katemera ndi mankhwala.Zouma zowuma mufiriji zimatha kukonzedwanso mosavuta ndi madzi kuti zisungidwe bwino, zoyendetsa ndikugwiritsa ntchito motsatira.

M'makampani azakudya, kuyanika kozizira kumapangitsa kuti zitheke kusunga zakudya zomwe zimatha kuwonongeka monga zipatso, ndiwo zamasamba, ngakhale mkaka.Njirayi imateteza kukoma kwachilengedwe ndi kapangidwe kazakudya ndikukulitsa moyo wawo wa alumali.Kuonjezera apo, zakudya zowuma mufiriji ndizopepuka komanso zophatikizika, zomwe zimawapangitsa kukhala otchuka ndi anthu oyenda m'misewu, oyenda m'misasa, ndi oyenda mumlengalenga chifukwa amalola kuti madzi aziyenda mosavuta.

Mwachidule, mfundo ya zowumitsira amaundana zimatengera njira ya sublimation, momwe mamolekyu amadzi oundana amasinthidwa kuchokera ku olimba kupita ku gasi pansi pa vacuum.Ukadaulo umatsimikizira kuti kapangidwe koyambirira ndi katundu wa chinthu zimasungidwa, ndikupangitsa kuti ikhale yamtengo wapatali m'mafakitale monga mankhwala ndi kukonza chakudya.Kuthekera kwa kuyanika kowumitsa kuti apange zinthu zowuma zokhala ndi shelufu yotalikirapo komanso kuwonongeka kochepa kwapangitsa kuumitsa kuzizira kukhala njira yomwe imakonda kuteteza padziko lonse lapansi.
