Mu gihe inganda zikora impapuro zihinduka zigana ku muvuduko no kunoza, igice cyo kumisha, nk'ikintu cy'ingenzi kigena ubwiza bw'impapuro n'umusaruro wazo, nticyigeze kireka gukoresha ikoranabuhanga ryacyo ry'ibikoresho. Nubwo utuzu twa kera tw'impapuro twuma umwuka dushobora guhaza ibyo zikeneye by'ibanze byo kumisha, duhura n'ibibazo nko kuzunguruka kw'impapuro, gushwanyagurika no kuvunika mu buryo bwihuse, bigatuma bigorana kumenyera ibyo zikenera mu gukora impapuro nke kandi zigezweho. Muri urwo rwego, utuzu twa VAC twuma (tuzwi kandi nka Vac rolls, ni ukuvuga utuzu twa vacuum dryer rolls) twavutse. Hamwe n'imikorere yatwo yihariye yo kumisha no gukamura, twahindutse ibikoresho by'ingenzi mu gice cyo kumisha imashini zikora impapuro zihuta cyane, bitanga inkunga y'ingenzi mu kunoza ireme n'imikorere myiza mu nganda zikora impapuro.

Imigozi yo kumisha ya VAC si ibikoresho bisanzwe bishyushya no kumisha, ahubwo ni ibikoresho byihuta cyane byo kumisha impapuro kandi byunganira ibyuma bikorana na silindiri zo kumisha zikoresha umwuka. Bikoreshwa cyane cyane mu buryo bwo kumisha impapuro zikoresha insinga imwe, kandi bikunze kuboneka mu mishinga yo gukora impapuro zikoreshwa mu buryo bw'umwimerere, impapuro zipfutse, ikarito yera, n'impapuro z'ibanze zikoresha corrugating. Bitandukanye n'uburyo busanzwe bwo gukora silindiri zo kumisha zikoresha umwuka zishingiye ku mwuka wo imbere mu gutanga ubushyuhe bwo kumisha, imigozi yo kumisha ya VAC ikora neza binyuze mu gushyushya umuvuduko, kandi icyarimwe bifasha kwihutisha isohoka ry'umwuka utose, binongera uburyo bwo kumisha muri rusange, bigatuma habaho uburyo bwo kumisha buhuriweho bwo "gushyushya + gushimangira imiterere y'impapuro".

Mu bijyanye n'imiterere y'imiterere, imigozi y'umuvuduko wa VAC igabanyijemo ubwoko bubiri kugira ngo ihuze n'umuvuduko utandukanye w'imodoka n'ibyo ikenera mu musaruro. Muri yo, umugozi wa Vac urimo imigozi ntusaba agasanduku k'umuvuduko. Ubuso bw'umugozi bufite imigozi ifite ubugari bwa mm 5 na mm 4 z'ubujyakuzimu, kandi imyobo mito inyuramo ikwirakwizwa hasi mu migozi, hamwe n'imyobo minini ku nkengero kugira ngo byorohereze gukurura. Ishobora gutanga uburebure bwa vacuum bwa 2kPa iyo ihujwe n'agasanduku gahumeka umwuka, kandi igipimo cyo gufungura kigenzurwa kuri 0.1% ~ 0.4%, bigatuma impapuro zifatana binyuze mu muvuduko utari mwiza unyura mu mwuka. Imiterere yayo ni yoroshye, ikwiriye gukorwa mu mashini zikoresha impapuro ziciriritse n'izihuta cyane. Ubundi bwoko ni umugozi wa Vac wo mu gasanduku k'umuvuduko, ufite imyobo ihamye cyangwa imyobo minini ku gishishwa cy'umugozi, hamwe n'icyumba cy'umuvuduko gishobora guhindurwa hakurikijwe ubugari bw'imbere, gihujwe neza na pompe y'umuvuduko. Ifite urwego rwo hejuru rw'ubushyuhe n'uburyo bwo kugenzura neza, byagenewe by'umwihariko imashini zikoresha impapuro zihuta cyane zifite umuvuduko urenga metero 1000 ku munota, zishobora guhangana neza n'ikibazo cyo kubungabunga urubuga rw'impapuro mu gihe cy'akazi gakomeye. Mu mishinga imwe n'imwe ikora cyane, imigozi ya Vac na silindiri z'umurinzi zikora igipimo nyacyo. Urugero, imashini icapa impapuro nziza cyane ifite umusaruro wa toni 130.000 ku mwaka ifite igice cyo kumisha kigizwe na silindiri 29 z'umurinzi w'umwuka n'imigozi myinshi ya Vac ifite umurambararo wa mm 1500. Umurongo wo hasi w'imigozi isanzwe y'umurinzi usimbura burundu imigozi ya Vac, bigatuma umusaruro uhoraho udakomeza gukurura imigozi kandi bikanoza cyane uburyo ikora neza.

Agaciro k'ingenzi k'imizingo y'imyunyungugu ya VAC gaturuka ku mahame yayo ya siyansi n'inyungu zayo mu mikorere yayo yihuta cyane. Mu musaruro nyawo, umurongo wo hejuru w'imizingo y'imyunyungugu y'umwuka ni wo utanga ubushyuhe bwo gushonga ubushuhe buri mu mpapuro, mu gihe umurongo wo hasi w'imizingo y'imyunyungugu ya VAC ifata neza impapuro ku buso bw'insinga yumye binyuze mu gitutu kibi, igakuraho neza imbaraga za centrifugal ziterwa no gukora vuba cyane, kandi igakemura by'umwihariko ibibazo by'inganda nko guhindagurika kw'impapuro, gushwanyagurika no kuvunika. Muri icyo gihe, umwuka unyura mu mufuka w'umwuka uhuzwa mu myobo y'imyunyungugu, ukihutisha gusohora umwuka utose, ugaca urwego rw'umwuka utose ku buso bw'impapuro, kandi ukanoza mu buryo butaziguye umuvuduko wo kumisha. Mu cyiciro cyo gufunga, imiterere y'imyobo minini ku mpande ishobora kongera ingaruka zo gufunga, ikarushaho kunoza umuvuduko wo gutsinda kw'impapuro, kandi ikagabanya igihe cyo gufunga. Impinduka zakozwe n'imashini ya Lee & Man Paper's PM15 yemeza ibi neza. Nyuma yo guhindura silindiri z’impapuro za mbere zikozwe mu buryo bwa "double-maning dryer" mo silindiri z’impapuro zikozwe mu buryo bwa "single-maning dryer" no kuzivugurura zikajya mu "Vac rolls", hamwe n’udusanduku tworoshye two guhagarara hamwe n’ibikoresho byo guhumeka mu mufuka, igipimo cyo gucika kw’impapuro cyagabanutseho 60%, igihe kitateganijwe cyo gucika cyagabanutseho 30%, kandi iyo hakorwaga impapuro z’ibanze za corrugating 70 ~ 90g / m² ku muvuduko wa 1000m / min, impapuro zangiritseho buri kwezi zari inshuro 10 gusa, kandi umusaruro wongeweho 3%.

Ugereranyije n'utuzu two kumisha imyotsi gakondo, aho imiyoboro ya VAC yumisha ishyirwa mu mwanya wayo irushaho kuba myiza mu gushimangira ubushyuhe bw'impapuro no kuyumisha by'inyongera, kandi byombi bikora isano yunganira kandi ihuzwa. Ku bijyanye n'isoko ry'ubushyuhe, imiyoboro ya VAC yumisha nta buryo bwo gushyushya ifite kandi yishingikiriza gusa ku gitutu kibi kugira ngo ikore, mu gihe utuzu two kumisha imyotsi dukoresha umwuka nk'isoko y'ubushyuhe kandi tugakorera imirimo yo kohereza ubushyuhe n'ubwumisha; ku bijyanye n'imiterere y'ubuso, imiyoboro ya VAC yumisha ikoresha imiterere y'imirongo cyangwa itobowe, mu gihe utuzu two kumisha imyotsi ahanini dufite ubuso bworoshye bwa chrome cyangwa icyuma gishongeshejwe; ku bijyanye n'imikorere, imiyoboro ya VAC yumisha yibanda ku gushimangira ubugari bw'impapuro, gukuraho ubushuhe by'inyongera, no kugabanya inenge z'impapuro, mu gihe utuzu two kumisha imyotsi twibanda ku gukwirakwiza ubushyuhe neza kugira ngo busoze ubushuhe bw'impapuro. Ku bijyanye n'ubushobozi bwo kumisha, ubushobozi bwo kumisha bw'umuyoboro umwe wa VAC ni buke, kandi imiyoboro ya VAC igera kuri 2 ~ 3 ingana na silindiri imwe isanzwe yumisha. Bityo rero, mu bikorwa bifatika, ni ngombwa guhuza mu buryo bwa siyansi umubare w'imizingo ya Vac na silindiri z'umuvuduko w'imodoka hakurikijwe umuvuduko w'imodoka n'ingano y'impapuro kugira ngo habeho uburinganire hagati y'imikorere myiza n'ikiguzi.

Dukurikije iterambere ry’ingamba za "karuboni ebyiri" hamwe n’impinduka mu buryo bw’ubwenge kandi buzigama ingufu mu nganda zikora impapuro, ikoreshwa ry’imizingo y’imyunyungugu ya VAC nayo igomba kwita ku kugenzura ikoreshwa ry’ingufu no kunoza uburyo bwo kubungabunga. Imizingo y’imyunyungugu ya VAC ikenera uburyo bwo gushyigikira uburyo bwo guhumeka no guhumeka, kandi ugereranije n’uburyo busanzwe bwo kumisha, ikoreshwa ryayo ry’ingufu n’ikiguzi cyo kuyibungabunga kiri hejuru gato, ariko kuzigama ingufu no kugabanya ikoreshwa bishobora kugerwaho binyuze mu kunoza tekiniki. Urugero, Lee & Man Paper yavuguruye agasanduku k’imyunyungugu ya SymRun mu gihe cyo guhindura, igabanya umutwaro w’umufana w’umwuka ku kigero cya 30% mu gihe yongera urugero rw’imyunyungugu; Valmet Finland yongereye intera iri hagati y’imizingo y’imyunyungugu ya Vac na silindiri z’imyunyungugu binyuze mu gupima no kwerekana imiterere ya 3D, yongereye inguni y’impapuro z’imyunyungugu, igabanya umubare w’imiyoboro y’umwuka n’iy’umwuka, kandi igabanya ikoreshwa ry’ingufu n’ikiguzi cyo kuyibungabunga. Mu kubungabunga buri munsi, ni ngombwa ko buri gihe usubiza inyuma imyobo n’imirongo y’imyunyungugu ya Vac ukoresheje umwuka ufunze kugira ngo wirinde kuziba, urebe imikorere y’imyunyungugu yo gufunga n’ubushyuhe bw’imyunyungugu icyarimwe, kandi ugenzure urugero rw’imyunyungugu mu buryo busabwa. Guhuza n'uburyo bwo guhumeka neza mu mufuka no mu buryo bwo gushyushya bishobora kongera cyane imikorere myiza yo kumisha no kugabanya ikoreshwa ry'umwuka ushyushye.

Hamwe no gukomeza kunoza ikoranabuhanga ry’imashini zikoresha impapuro zihuta cyane hamwe n’ubwiyongere bw’ibicuruzwa by’impapuro zigezweho, ivugurura ry’ikoranabuhanga rya VAC dryer rolls naryo rizagenda rigana ku buryo bunoze, kubungabunga ingufu, n’ubwenge. Mu gihe kizaza, hifashishijwe ikoranabuhanga rigezweho nka CFD simulation no kubara imibare, igishushanyo mbonera cy’umwobo n’imiterere y’icyumba cy’impapuro zikoresha impapuro zikoreshwa mu gufunga bishobora kunozwa cyane kugira ngo binoze uburyo bwo kugenzura umuvuduko mubi n’urwego rwo guhuza impapuro; hamwe no kumenya neza no gusesengura amakuru menshi, kugenzura imbaraga z’urwego rw’impapuro zikoreshwa mu gufunga bishobora kugerwaho kugira ngo bihuze n’ibikenewe mu gukora impapuro zitandukanye n’umuvuduko utandukanye w’imodoka; icyarimwe, binyuze mu kuvugurura ibikoresho no kunoza imiterere, ikoreshwa ry’ingufu n’ibikoresho bishobora kugabanuka, kandi igihe cyo kuzikoresha gishobora kongerwa. Nk’ “igikoresho cyo kubungabunga ubuziranenge” ku buryo bwo kumisha impapuro zihuta cyane, VAC dryer rolls ntikemura gusa ibibazo byinshi byo kumisha bisanzwe mu gihe cy’akazi kihuta cyane, ahubwo inafasha ibigo bikora impapuro kunoza ubuziranenge bw’ibicuruzwa no kunoza imikorere myiza, bikongera imbaraga nshya mu iterambere ry’inganda zikora impapuro.
