Kusiyanitsa kwazinthu ndi kuchuluka kwa kagwiritsidwe ntchito ka matumba oyika vacuum

Mitundu yayikulu yogwiritsira ntchito matumba onyamula vacuum ndi gawo lazakudya, ndipo imagwiritsidwa ntchito pazakudya zosiyanasiyana zomwe ziyenera kusungidwa pamalo opanda vacuum. Amagwiritsidwa ntchito potulutsa mpweya m'matumba apulasitiki, kenaka amawonjezera nayitrogeni kapena mpweya wina wosakanizika womwe suwononga chakudya.
1. Pewani kukula kwa tizilombo toyambitsa matenda m'malo opanda phokoso, pewani kuipitsidwa kwa malo ozungulira, kuchepetsa kuchuluka kwa okosijeni m'zakudya, ndikulepheretsa kukula kwa tizilombo toyambitsa matenda.
2. Thumba la vacuum package limatha kuletsa chinyezi cha chakudya kuti chisasunthike, kuchepetsa kutaya kwa madzi ndikusunga mtundu wazinthuzo.
3. Kukongola kwa thumba losungiramo vacuum palokha kumapangitsa kuti anthu azikhala ndi chidziwitso chodziwika bwino cha mankhwala ndikuwonjezera chilakolako chogula.
Tiyeni tiyankhule za kusankha kwapadera kwa matumba osungiramo vacuum, ndi kusankha mitundu yosiyanasiyana ya matumba opangira vacuum ndi yosiyana.
PE zakuthupi: zoyenera matumba onyamula a vacuum otsika kutentha. Kuyika zambiri pazinthu zowuma.
PA zakuthupi: kusinthasintha kwabwino komanso kukana kwamphamvu kwambiri.
Zinthu za PET: onjezerani mphamvu zamakina azinthu zonyamula katundu, ndipo mtengo wake ndi wotsika.
AL: AL ndi zojambulazo za aluminiyamu, zomwe zimakhala ndi zotchinga zazikulu, zotchinga, komanso kukana chinyezi.
PVA zakuthupi: kuchuluka kwa zotchinga katundu, zokutira zotchinga kwambiri.
Zida za RCPP: Zomwe zimagwiritsidwa ntchito kwambiri pamatumba ophikira otentha kwambiri, oyenera kugwiritsa ntchito kutentha kwambiri.
Matumba osungiramo vacuum amapangidwa ndi polyvinylidene chloride, polyester, ndi polyamide zipangizo zomwe zimakhala ndi anti-oxidative, ndiko kuti, zimateteza mpweya wabwino komanso kuchepa kwabwino; ena a iwo adzapangidwa ndi nayiloni, filimu poliyesitala ndi polyethylene Mipikisano wosanjikiza zipangizo. Polyvinylidene chloride zakuthupi zomwe tazitchula pamwambapa ndi mtundu wa filimu yomwe ili ndi zotsatira zabwino kwambiri zotsekereza mpweya ndi nthunzi wa madzi, koma sizimalimbana ndi kusindikiza kutentha. Polyester ili ndi mphamvu yolimba kwambiri. Nayiloni ili ndi zotchinga zabwino za okosijeni komanso kukana kutentha, koma kuchuluka kwa mpweya wamadzi ndikokulirapo ndipo mtengo wopangira ndi wokwera. Chifukwa chake, ambiri opanga ambiri amasankha zida zophatikizika kuti asankhe zabwino ndi zovuta zamakanema osiyanasiyana. Chifukwa chake, makasitomala ambiri akamagwiritsa ntchito ndikusankha matumba oyika vacuum, tiyenera kusanthula zomwe zili mkati ndikusankha zida zoyenera malinga ndi mawonekedwe awo.
