Tsvina iri pamadziro ekuvirisa isanganiswa ye inorganic and organic matter, iyo yakaoma kuchenesa nemushonga mumwe wekuchenesa.Kana chete caustic soda inoshandiswa pakuvirisa kuchenesa, inongoshanda kubvisa organics.Chete kana tembiricha yekuchenesa yasvika pamusoro pe80 ℃, inogona kuwanikwa iri nani yekuchenesa maitiro;pakuchenesa, imwe nitric asidhi inoshandiswa pakuchenesa, iyo inongove neimwe mhedzisiro pane inorganic zvinhu uye inenge isingashande kune organic zvinhu.Naizvozvo, kuchenesa kwekuvirisa kunoda alkaline yekuchenesa mhinduro uye ine acidic yekuchenesa mhinduro.
Matangi ekuvirisa anocheneswa kutanga obva aitwa sterilized.Chinodiwa pakuita sterilization inobudirira ndechekuti tsvina yacho inonyatsocheneswa.Mumabasa ekugadzira chaiwo, inogara yacheneswa kutanga yozoitwa sterilized.
Yekuchenesa tangi yekuvirisa: buritsa yakasara kabhoni dhaidhirodhi gasi mutangi.Mhepo yakamanikidzwa inobvisa kabhoni dhaikisaidhi kwemaminitsi gumi kusvika gumi nemashanu.(zvichienderana nemhepo yakamanikidzwa inoyerera).Mbiriso yakasara mufermenter yakashambidzwa nemvura yakachena, uye fermenter yakashambidzwa nepakati nemvura inopisa pa 90 ° C kuti ichidziye.Bvisa vharuvhu yemusanganiswa wekuburitsa uye aseptic sampling vharafu, shandisa bhurashi rakanyikwa mulye kuti uichenese, uye woimisazve.Kuvirisa kunocheneswa nekutenderedza mvura ine alkaline inopisa pamusoro pe1.5-2% pa80°C kwemaminetsi makumi matatu kusvika makumi matanhatu.Geza tangi yekuvirisa nguva nenguva nemvura inopisa kana inodziya kuita kuti mvura inobuda isarerekera, uye wogeza tangi rekuvirisa nguva nenguva nemvura inotonhora kusvika patembiricha yekamuri.Geza ne nitric acid solution ine concentration ye1% kusvika 2% kwemaminitsi gumi nemashanu.Iyo yekuvirisa yakagezwa nemvura kuti isaite mudhini.
Zvinotendwa kuti kuburikidza nekucheneswa kwakasimba uye kuuraya hutachiona, kugadzikana kwedoro rakabikwa kuchawedzera kuvandudzwa.
