Maitiro ekushanda kwemuchina wekuvhara chikafu

Maitiro ekushanda kwemuchina wekuvhara chikafu ndeaya anotevera:

Chifukidziro chekamuri re vacuum, pombi ye vacuum, imba ye vacuum yakatanga kupomba mweya mu vacuum state, mabhegi ari mu vacuum panguva imwe chete, pointer ye vacuum gauge kuti ikwire kune vacuum yakarongwa (Panosvika nguva yekutumira ISJ control) Pombi ye vacuum inomira kushanda, uye vacuum inomira. Mu vacuum, panguva imwe chete basa revanhu vaviri rinoitwa ne three-way magnet valve (IDT, vacuum heat sealing, thermal in situ).

Muchina wekuvhara chikafu chevacuum ndiro basa guru reokisijeni, unobatsira kudzivirira kuora kwechikafu, musimboti wawo uri nyore, nekuti kuchinja kwechikafu kunokonzera chakuvhuvhu kunonyanya kukonzerwa nebasa rezvipembenene, uye tupukanana twakawanda (Sekunge chakuvhuvhu nembiriso). Kupona kunoda okisijeni, uye uchishandisa musimboti uyu, kurongedza nechikafu mukati mesero utsi hweokisijeni, zvinorasikirwa nenzvimbo yekurarama kwetupukanana. Mhedzisiro yekuyedza inoratidza: kana huwandu hweokisijeni mupakeji & le; 1%, kukura kwetupukanana uye mwero wekuberekana kwaderera zvakanyanya, huwandu hweokisijeni & le; 0.5%, tupukanana twakawanda tuchadzorwa mukati uye kumisa kubereka. (Cherechedza: kurongedza vacuum kunogona kudzivirira kubereka kwetupukanana tweanaerobic uye maitiro eenzyme anokonzerwa nekuchinja kwechikafu uye kuchinja kweruvara, saka zvichiri kudiwa kusanganiswa nedzimwe nzira dzekubatsira, dzakadai sekuchengetwa kwechando, kuomeswa nemvura, kupiswa kwekupisa kwakanyanya, kupiswa nemwaranzi, kupiswa ne microwave, kunyungudutsa, nezvimwewo.)
