Abstract: Chimiro chemicrobial chezvinovirisa chine simba guru pamhando yedoro.Kuchena uye kusachena ndicho chinodiwa pakubata hutsanana mukugadzira doro.Iyo yakanaka CIP system inogona kunyatso kuchenesa yekuvirisa.Matambudziko ekuchenesa nzira, nzira yekuchenesa, nzira yekuchenesa, yekuchenesa agent / sterilizant kusarudzwa uye kushanda kwehutano hweCIP system yakakurukurwa.
Nhanganyaya
Kuchenesa uye sterilization ndiro basa rekutanga rekugadzira doro uye yakakosha tekinoroji chiyero chekuvandudza mhando yedoro.Chinangwa chekuchenesa uye sterilization ndechekubvisa zvakanyanya sezvinobvira tsvina inogadzirwa nemukati memadziro epombi uye zvishandiso panguva yekugadzira, uye kubvisa kutyisidzira kwekuparadzika ma microorganisms pakubika doro.Pakati pavo, chirimwa chekuvirisa chine izvo zvakanyanya kudiwa kune ma microorganisms, uye yekuchenesa uye sterillization basa inodarika 70% yebasa rose.Parizvino, vhoriyamu yekuvirisa iri kuramba ichikura, uye pombi inotakura zvinhu iri kuramba ichireba uye ichireba, izvo zvinounza matambudziko mazhinji pakuchenesa nekubvisa.Maitiro ekuchenesa nemazvo uye nemazvo uye nekubirisa kuvirisa kuzadzisa izvo zvino "pure biochemical" zvinodiwa zvedoro uye kuzadzisa zvinodiwa nemutengi zvemhando yechigadzirwa inofanira kukosheswa zvakanyanya nevashandi vanobika doro.
1 yekuchenesa michina uye zvinoenderana nezvinhu zvinokanganisa kuchenesa maitiro
1.1 nzira yekuchenesa
Munguva yekugadzirwa kwedoro, pamusoro pemidziyo inosangana nezvinhu inoisa imwe tsvina nekuda kwezvikonzero zvakasiyana.Zvekuvirisa, izvo zvinosvibisa zvinonyanya kusvibiswa mbiriso uye mapuroteni, hop uye hop resin makomisheni, nematombo edoro.Nekuda kwesimba remagetsi uye zvimwe zvinhu, tsvina iyi ine imwe adsorption simba pakati pepamusoro pemadziro emukati ekuvirisa.Zviripachena, kuti udzinge tsvina kubva pamadziro etangi, imwe huwandu hwesimba hunofanira kubhadharwa.Iri simba rinogona kuva simba remagetsi, kureva, nzira yekutsvaira kwemvura ine imwe simba rekuita;kemikari simba rinogonawo kushandiswa, sekushandisa acidic (kana alkaline) yekuchenesa agent kuti isunungure, kuputika kana kunyungudutsa tsvina, nokudaro ichisiya yakabatanidzwa;Isimba rinopisa, ndiko kuti, nekuwedzera kutonhora kwekuchenesa, kukurumidza kushandiswa kwemakemikari uye kukurumidza kuchenesa.Muchokwadi, iyo nzira yekuchenesa kazhinji inokonzeresa kusanganiswa kwemakanika, kemikari uye tembiricha mhedzisiro.
1.2 Zvinhu zvinokanganisa kuchenesa maitiro
1.2.1 Huwandu hwekunamira pakati pevhu nepamusoro pesimbi hunoenderana nekukwasharara kwepamusoro kwesimbi.Iyo yakanyanyisa simbi yepamusoro, iyo yakasimba iyo adsorption pakati petsvina nepamusoro, uye zvakanyanya kuoma kuchenesa.Equipment inoshandiswa pakugadzira chikafu inoda Ra<1μm;hunhu hwechinhu chepamusoro chemidziyo inokanganisawo adsorption pakati petsvina uye pamusoro pemidziyo.Semuenzaniso, kucheneswa kwezvinhu zvakagadzirwa zvakanyanya kuoma kana zvichienzaniswa nekucheneswa kwesimbi isina tsvina.
1.2.2 Hunhu hwetsvina zvakare hune humwe hukama nemhedzisiro yekuchenesa.Zviri pachena kuti zvakaoma zvikuru kubvisa tsvina yekare yakaomeswa pane kubvisa itsva.Naizvozvo, mushure mekunge kutenderera kwekugadzira kwapera, yekuvirisa inofanirwa kucheneswa nekukurumidza, izvo zvisiri nyore, uye ichacheneswa uye sterilized isati yashandiswa kunotevera.
1.2.3 Kusimba kwe Scour chimwe chinhu chikuru chinokanganisa maitiro ekuchenesa.Pasinei nepombi yekutsvaira kana tangi madziro, iyo yekuchenesa mhedzisiro iri nani chete kana mvura yekuwachisa iri mumhirizhonga.Naizvozvo, zvinodikanwa kunyatso kudzora kusimba uye chiyero chekuyerera kuitira kuti pamusoro pechishandiso chinyoroveswe zvakakwana kuti ive nechokwadi chekuchenesa mhedzisiro.
1.2.4 Kubudirira kwemugadziri wekuchenesa pachako kunoenderana nerudzi rwayo (asidhi kana chigadziko), basa uye kuisa pfungwa.
1.2.5 Muzviitiko zvakawanda, maitiro ekuchenesa anowedzera nekuwedzera kwekushisa.Nhamba huru yekuedzwa yakaratidza kuti kana rudzi uye kusungirirwa kwemugadziri wekuchenesa zvakatemwa, mhedzisiro yekuchenesa pa50 ° C ye5 min uye kushambidza pa20 ° C kwe30 min zvakafanana.
2 fermenter CIP kuchenesa
2.1CIP maitiro ekushanda uye maitiro ayo pakuchenesa maitiro
Nzira yakajairika yekuchenesa inoshandiswa nevanobikira doro vemazuva ano ndeyekuchenesa munzvimbo (CIP), inova nzira yekuchenesa uye sterilizing michina uye pombi pasina kupatsanura zvikamu kana mafittings emidziyo pasi pemamiriro akavharwa.
2.1.1 Magaba mahombe akaita semavirisi haagone kucheneswa nenzira yekuchenesa.Iyo in-situ yekuchenesa yefermentor inoitwa kuburikidza ne scrubber cycle.Iyo scrubber ine marudzi maviri eyakagadziriswa bhora yekuwachisa mhando uye rotary jet rudzi.Mvura yekugezesa inopfapfaidzwa mukati metangi kuburikidza nemuscrubber, uye ipapo mvura yekugeza inoyerera ichidzika nemadziro etangi.Mumamiriro ezvinhu akajairika, mvura yekugeza inoumba firimu yakasungirirwa patangi.Pamadziro etangi.Mhedzisiro yeichi mechanical chiito idiki, uye kuchenesa maitiro kunonyanya kuwanikwa nekemikari chiito chekuchenesa mumiririri.
2.1.2 Iyo yakagadziriswa bhora washing type scrubber ine nzvimbo yekushanda ye 2 m.Kune mahorizontal fermenters, akawanda scrubbers anofanira kuiswa.Kudzvinyirirwa kwemvura yekuwachisa pakubuda kwe scrubber nozzle inofanira kuva 0.2-0.3 MPa;for vertical fermenters Uye nzvimbo yekuyeresa yepressure panobuda pombi yekuwachisa, kwete kungorasikirwa kwekumanikidza kunokonzerwa nekupokana kwepombi, asiwo pesvedzero yehurefu pakumanikidza kwekuchenesa.
2.1.3 Kana kudzvinyirirwa kwakanyanya kuderera, radius yekuita ye scrubber idiki, chiyero chekuyerera hachina kukwana, uye sprayed yekuchenesa mvura haigoni kuzadza tangi rusvingo;kana kudzvinyirirwa kwakanyanyisa, mvura yekuchenesa ichaita mhute uye haigoni kuumba kuyerera kunodzika pamadziro etangi.Iyo firimu remvura, kana yakapfapfaidzwa yekuchenesa mvura, inobvondokera kumashure kubva kumadziro etangi, ichideredza kuchenesa.
2.1.4 Kana iyo midziyo inofanira kucheneswa yakasviba uye dhayamita yetangi yakakura (d> 2m), rotary jet type scrubber inowanzo shandiswa kuwedzera washing radius (0.3-0.7 MPa) kuwedzera washing radius uye kuwedzera washing radius.Iyo mechanical chiito chekusuka chinowedzera descaling effect.
2.1.5 Rotary jet scrubbers inogona kushandisa yakaderera purge fluid flow rate pane yeball washer.Sezvo svikiro rekushambidza richipfuura, mucheki anoshandisa recoil yemvura kutenderedza, kupuruzira uye kudonhedza zvimwe, nekudaro kuvandudza maitiro ekuchenesa.
2.2 Kufungidzira kwekuchenesa mvura inoyerera
Sezvambotaurwa pamusoro apa, iyo yekuvirisa inoda kuve nekumwe kuyerera uye kuyerera kwekuyerera kana uchichenesa.Kuti uve nechokwadi chekuwanda kwakakwana kwemvura inoyerera uye kugadzira mhirizhonga inoenderera mberi, zvinodikanwa kubhadhara kuyerera kwepombi yekuchenesa.
2.2.1 Pane nzira dzakasiyana dzekufungidzira mwero wekuyerera kwemvura yekuchenesa yekuchenesa matangi epasi pekoni.Nzira yechinyakare inongotarisa denderedzwa retangi, uye inotarirwa muhupamhi hwe1.5 kusvika 3.5 m3/m•h zvichienderana nekuoma kwekuchenesa (kazhinji muganho wakaderera wetangi diki uye muganho wepamusoro wetangi hombe. )Tangi repasi redenderedzwa repasi rine dhayamita 6.5m rine denderedzwa rinoita 20m.Kana 3m3 / m•h inoshandiswa, kuyerera kwemvura yekuchenesa inenge 60m3 / h.
2.2.2 Nzira itsva yekufungidzira yakavakirwa pakuti huwandu hwemetabolites (sediments) inonaya parita imwe yekutonhodza wort panguva yekuvirisa inogara iripo.Kana iyo dhayamita yetangi ichiwedzera, nzvimbo yemukati yenzvimbo pane unit tank simba inoderera.Nekuda kweizvozvo, huwandu hwehutsvina hwemutoro panzvimbo yeyuniti hunowedzera, uye kuyerera kwemvura yekuchenesa kunofanirwa kuwedzerwa maererano.Inokurudzirwa kushandisa 0.2 m3 / m2•h.Chiviriro chine simba re 500 m3 uye dhayamita ye6.5 m ine nzvimbo yemukati inenge 350 m2, uye kuyerera kwemvura yekuchenesa inenge 70 m3 / h.
3 nzira dzinowanzoshandiswa uye maitiro ekuchenesa mafermenters
3.1 Zvinoenderana nekushisa kwekushanda kwekuchenesa, inogona kukamurwa kuita inotonhora yekuchenesa (yakajairika tembiricha) uye inopisa kuchenesa (kupisa).Kuti uchengetedze nguva uye mvura yekugeza, vanhu vanowanzogeza pane tembiricha yepamusoro;kuitira kuchengetedza kwekushanda kwematangi makuru, kuchenesa kunotonhora kunowanzoshandiswa pakuchenesa matangi makuru.
3.2 Zvinoenderana nerudzi rwekuchenesa agent inoshandiswa, inogona kukamurwa kuita acidic kuchenesa uye alkaline kuchenesa.Alkaline washing inonyanya kukodzera kubvisa organic tsvina inogadzirwa muhurongwa, yakadai sembiriso, mapuroteni, hop resin, nezvimwewo;pickling inonyanya kubvisa zvinosvibisa zvinogadzirwa muhurongwa, senge calcium munyu, magnesium munyu, matombo edoro, nezvimwe zvakadaro.
