Kuyerera kwekushanda:
1, vacuum: vacuum kamuri yakavharwa chivharo, basa repombi yekutsvaira, kamuri yekutsvaira yakatanga kupomba vacuum, vacuum mubhegi panguva imwe chete, iyo yekugezera yegeji yekunongedza inosimuka, ichisvika kune yakatemerwa vacuum (inodzorwa nenguva yekudzosera ISJ) pombi yekutsvaira kusvika rega kushanda, vacuum stop. Panguva imwechete yebasa rekutsvaira, maviri-nzvimbo matatu-nzira nhatu solenoid vharafu IDT basa, kupisa kuvharira gasi mukamuri vacuum, kupisa kudzvanya furemu ramba iripo.
2, kupisa chisimbiso: IDT kuputika, mhepo yekunze kuburikidza nepamusoro pemhepo inopinza mukamuri yekupisa yekuvhara gasi, kushandiswa kwekamuri yevacuum ine mutsauko wekumanikidza pakati pekamuri yekuisa chisimbiso chegasi, kupisa kuvharisa gasi kamuri inoputika inflatable kuwedzera, kuitira kuti kupisa kupisa furemu pasi, dzvanya muromo webhegi; panguva imwecheteyo, iyo inopisa sealing transformer inoshanda, tanga kuisa chisimbiso; panguva imwe chete, iyo nguva inotumira 2SJ basa, masekondi mashomanana mushure mekuita, kupera kwekupisa chisimbiso.
3, kudzokera kumhepo: mbiri-nzvimbo mbiri-nzira solenoid vharafu 2DT inopfuura, mhepo ichipinda mukamuri yekutsvaira, iyo yekugezera yegeji yekunongedzera kumashure kune zero, inopisa yekutsikisa furemu inotsamira pakusetazve chitubu, imba yekutsvaira yakavhurika chivharo.
Mechanism yekuita:
Basa guru rekuputira vacuum ndiro deoxygenation, kudzivirira kuparara kwezvokudya, nheyo yacho iri nyore, ndeyokubvisa okisijeni uye masero ezvokudya muhomwe, kuitira kuti ma microorganisms arasikirwe nehupenyu hwavo. Ongororo dzinoratidza kuti: apo oksijeni yekuisa muhomwe iri pasi pe1%, kukura uye kubereka kwema microorganisms kuchadonha zvakanyanya, apo oxygen concentration iri pasi pe0.5%, microorganisms dzakawanda dzichadziviswa uye dzinorega kubereka. (Cherechedza: vacuum packaging haigoni kutadzisa kubereka kweanaerobic bacteria uye enzyme reaction inokonzerwa nekuora kwechikafu uye kushanduka kwemavara, saka inoda kusanganiswa nedzimwe nzira dzekubatsira, dzakadai sefiriji, kukurumidza kutonhora, kupera simba, kupisa kwepamusoro-tembiricha, irradiation. sterilization, microwave sterilization, pickling yemunyu, nezvimwe.
