Sechinhu chikuru chemuchina wekuomesa nechando, pombi ye vacuum inoita basa rakakosha mukuomesa nechando. Muchina wekuomesa nechando (lyophilizer) chishandiso chinoshandiswa zvakanyanya mumaindasitiri ezvekudya, mishonga, uye makemikari. Nekuomesa nekuisa zvinhu pasi pemvura kana tembiricha yakaderera uye kumanikidzwa kwakaderera, inoita kuti hunyoro husavepo kana kuti hushoma, zvichiita kuti nguva yekushanda kwechinhu ichi iwedzere uye ivandudze kugadzikana kwacho.
Basa Guru rePombi yeVacuum
Basa guru repombi yekubvisa mvura mufiriji nderekugadzira nekuchengetedza nzvimbo yekubvisa mvura, iyo inokosha pakuomesa kwefiriji. Pombi yekubvisa mvura inogara ichibvisa gasi kubva mufiriji, ichideredza kumanikidzwa kwemukati zvishoma nezvishoma. Kana kumanikidzwa kwadzikira kusvika padanho rakati, hunyoro huri muchinhu hunotanga kuchinja zvakananga kubva pachinhu chakaoma kuenda kugasi - maitiro anonzi sublimation - nokudaro zvichiita kuti chinhu chiome nefriji.
Zvikurukuru, kushandiswa uye basa repombi ye vacuum mufiriji yekuomesa zvinoratidzwa muzvinhu zvinotevera:
Kugadzira nzvimbo isina chinhu:Pombi yekuomesa inobvisa mhepo kubva mukamuri rekuomesa, ichideredza kumanikidzwa kuri mukati uye ichigadzira nzvimbo yekuomesa. Nzvimbo iyi inobvumira chando chiri muchigadzirwa kuti chinyungudike zvakananga muutsi hwemvura pasi pekumanikidzwa kwakaderera, zvichidzivirira maitiro echando kunyunguduka kuita mvura uye yobva yapwa, nokudaro zvichivandudza kushanda zvakanaka kwekuomesa.
Kudzora kumanikidzwa:Munguva yekuomesa nechando, pombi ye vacuum inogona kugadzirisa nekuchengetedza kumanikidzwa mukati mekamuri yekuomesa mukati menzvimbo yakakodzera. Izvi zvakakosha kuti sublimation ishande zvakanaka, nekuti zvinhu zvakasiyana uye zvigadzirwa zvine mwero wakasiyana we sublimation pasi pekumanikidzwa kwakasiyana.
Kuvandudza mashandiro ekugadzira uye kunaka kwechigadzirwa:Midziyo yepombi ye vacuum inoshanda zvakanyanya inogona kusvika padanho re vacuum rinodiwa nekukurumidza, kupfupisa nguva yekuomesa nechando, uye kuwedzera kushanda zvakanaka kwekugadzira. Panguva imwe chete, inodzivirira mhando yezvigadzirwa nekuderedza marara ane tsvina. Izvi zvakakosha zvikuru kumakambani anogadzira zvinhu zvakaomeswa nechando, sezvo zvichikanganisa zvakananga kukwikwidzana kwezvigadzirwa mumusika.
Kuchengetedza mari yemagetsi:Pombi yakanaka ye vacuum inogona kuwana huwandu hunodiwa hwe vacuum munguva pfupi, zvichiita kuti simba rideredzwe. Kune michina yekuomesa inoomesa inoramba ichishanda, izvi zvinoita kuti simba rirambe richichengetwa zvakanyanya.
Mhando uye Sarudzo dzeMapombi eVacuum
Mhando dzemapombi evacuum anoshandiswa mufreezer dryers dzinosanganisira rotary vane vacuum pumps, centrifugal vacuum pumps, uye turbomolecular pumps. Rudzi rumwe nerumwe rune zvarwakanakira uye mamiriro akakodzera:
Pombi yekuputira ine rotary vane vacuum:Inozivikanwa nehukuru hwayo hudiki, huremu hwayo hushoma, chimiro chayo chiri nyore, uye kugadzirisa kuri nyore, pombi iyi inoshandiswa zvakanyanya mukushandiswa kunoda vacuum yakakwira kana kumhanya kukuru kwekupomba. Inoburitsa gasi kuburikidza nechinhu chinotenderera chine vacuum uye inogona kuwana vacuum yakakwira munguva pfupi, ichikurumidzisa sublimation yehunyoro.
Pombi yekuputira mvura yeCentrifugal:Rudzi urwu rwakakodzera masisitimu epombi dzevacuum dzakakura, dzine simba rekupomba nekukurumidza, uye gasi rakakura. Rinoshandisa simba re centrifugal rinogadzirwa nekutenderera nekukurumidza kuti ribudise gasi, richizadzisa zvinodiwa pakugadzirwa kwaro.
Pombi yeTurbomolecular:Pombi iyi ine simba guru, ine vacuum yakawanda, saizi shoma, uye inoshandisa simba shoma, yakanakira masisitimu evacuum akanyatsogadzirwa. Inoburitsa gasi kuburikidza neturbine inotenderera nekukurumidza uye inogona kupa simba shoma, ichizadzisa zvinodiwa pakugadzirira zvinhu zvakachena zvakanyanya.
Pakusarudza pombi ye vacuum, zvinhu zvakaita sekumhanya kwekupomba, huwandu hwesimba rekushanda, kuchena kwenzvimbo yekushanda, uye mari yekugadzirisa zvinofanirwa kufungwa nezvazvo. Panguva imwe chete, kuti ive nechokwadi chekuti muchina wekuomesa unoomesa nechando unoshanda zvakanaka uye kuti uwedzere hupenyu hwawo hwekushanda, kugadzikiswa kwepombi ye vacuum nguva dzose kunodiwa - kusanganisira kutarisa zvisimbiso, kugona kwayo kusveta, uye kutsiva oiri yepombi ye vacuum.
Mhedziso
Sechinhu chikuru chemuchina wekuomesa nechando, mashandiro epombi yekuomesa nechando anokanganisa zvakananga kushanda zvakanaka uye kuchengetedzeka kwemidziyo. Nekugadzira nekuchengetedza nzvimbo yekuomesa nechando, pombi yekuomesa nechando haingogadzirise kushanda zvakanaka kwemaitiro ekuomesa nechando uye mhando yechigadzirwa, asiwo inobatsira mabhizinesi kuchengetedza mari yemagetsi. Saka, pakusarudza pombi yekuomesa nechando, zvakakosha kufunga nezvezvinhu zvakasiyana-siyana zvichienderana nezvinodiwa chaizvo, kuve nechokwadi chekuti michina yekuomesa nechando yepamusoro yasarudzwa, uye kugadzirisa nguva dzose kuti ive nechokwadi chekuti dryer yekuomesa nechando inoshanda zvakanaka uye kuwedzera hupenyu hwayo hwekushanda.
