Kushandisa muchina wekurongedza chikafu chinoputirwa mupurasitiki (vacuum packaging machine) zvinotora nguva yakareba sei kuti chikafu chigare chakaputirwa mupurasitiki?

Gara uchitsanangura zvakanakira kushandiswa kwechikafu, saka vanhu vazhinji vanobvunza nezve vacuum cleaner. muchina wekurongedza inogona kuiswa nguva yakareba sei mushure mekurongedza vacuum, kana ichienderana nekuchengetedzeka kwechikafu nezvimwewo zvakatevedzana matambudziko. Muchina wekurongedza vacuum unogona kuburitsa mweya otomatiki mukati mebhegi, zvichiita kuti upedze mushure mekusunga vacuum. Tekinoroji yekurongedza vacuum yakatanga muma1940s. Muna 1950, polyester, polyethylene purasitiki firimu yakashandiswa zvinobudirira mukurongedza vacuum, kubva ipapo, kurongedza vacuum uye yakawana kukura nekukurumidza. Muchina wekurongedza vacuum unowanzo shandiswa muindasitiri yechikafu, nekuti mushure mekurongedza vacuum, antioxidant yechikafu, kuti uwane chinangwa chekuchengetedza kwenguva refu. Dambudziko nderekuti unofanirwa kupasa bvunzo kuti uwane mhedzisiro chaiyo. Sezvatakaona hupenyu hwesherufu hwemachira echikafu, chete kana bhizinesi rikaita dhipatimendi rehunyanzvi mushure mebvunzo, rinogona kuziva.

asi zvakare pawebhusaiti nhasi kuti muunganidze mibvunzo yakawanda nezvenguva yekurongedza chikafu muchina wevacuum. Muchina wekuisa otomatiki muchina wevacuum wakakodzera kucheka nyama yakaomeswa nechando, nyama itsva inotonhora, zvigadzirwa zvesoya zvakaita senyama, hove, chikafu chekudya chemazuva ano, zvigadzirwa zvemishonga, michina yekurapa, zvigadzirwa zvemagetsi, zvigadzirwa zvehardware, zvigadzirwa zveindasitiri zvakaita sevacuum kana gasi, kurongedza kwave tsika yekurongedza chikafu mune ramangwana. Ngatitarisei kuti tinofanira kuziva kuti chii chinodiwa. Mhando dzenguva yekurongedza chikafu nechikafu zvine chekuita nekugadziriswa kwevacuum usati warongedza. Mhando dzakasiyana dzechikafu, kana maitiro akasiyana ekugadzirisa, kurongedza vacuum kwakasiyana mushure menguva yekuchengetera patembiricha yemukamuri. { +- *} Zvichibva pane zvakaitika, semuenzaniso, kana kuchengetedzwa kwechikafu patembiricha yemukamuri kwemazuva maviri, chingave chiri zvigadzirwa zvitsva zvekurima kana zvigadzirwa zvenyama zvakagadziriswa zvishoma. Kana zvakadaro, mushure mekurongedza vacuum, zvinogona kuwedzerwa kusvika mazuva matanhatu. Zvimwe zvinogona kuwedzerwa kusvika mazuva gumi nemasere. Nguva inogara kwenguva refu ipfupi, michero yakaomeswa, kunyange kupfuura mwedzi gumi nemiviri. Inofanira kuita kuyedza kwechigadzirwa chaicho.

Zvinotevera zvinonyanya kutaura nezve musimboti wekuchengetedza kurongedza kwevacuum, kuti tinzwisise dambudziko rekugara kwenguva refu: kushandisa vacuum packing okisijeni ndiwo mabasa makuru emuchina wekupaka vacuum, kudzivirira kuora kwechikafu, musimboti wacho uri nyore. Nekuti kuora kwechikafu kunonyanya kukonzerwa nebasa rezvipembenene, uye tupukanana twakawanda (Sezvakaita chakuvhuvhu nembiriso). Zvinodiwa zveokisijeni kurarama, uye kurongedza vacuum ndiko kushandisa musimboti uyu. Chikafu chebhegi neokisijeni mumasero zvabviswa, tupukanana twakarasikirwa nezvakatipoteredza; 。 Mhedzisiro inoratidza kuti kana huwandu hweokisijeni mubhegi huchinge huri pasi pe1%, kukura kwehuwandu hwemabhakitiriya ekubereka hwakaderera zvakanyanya, huwandu hweokisijeni & le; Kusvika zero. 5%, tupukanana twakawanda twakadziviswa, kurega kubereka. Cherechedza: kurongedza vacuum kunogona kudzivirira kuberekana kwebhakitiriya anaerobic uye maitiro eenzyme anokonzerwa nekuora kwechikafu, nechando, kuoma, sterilization yekupisa kwakanyanya, sterilization yemwaranzi, sterilization ye microwave, munyu nedzimwe nzira dzekubatsira. Kubvisa mhepo mu vacuum hakungodziviriri kukura kwehutachiona chete, asi rimwe basa rakakosha nderekudzivirira kusvibiswa kwechikafu, nekuti chikafu chine mafuta akawanda asina kuguta, kusvibiswa neokisijeni, kunoita kuti kunaka kwechikafu kuchinje. Pamusoro pezvo, kusvibiswa kunoitawo kuti vhitamini A nevhitamini C zvirasikirwe, ruvara rwechikafu rusagadzikana pasi pesimba reokisijeni, uye kunoita kuti ruvara ruve rwakasviba. Okisijeni inogona kudzivirira kuora kwechikafu zvinobudirira, saka, inochengetedza ruvara rwayo, kunhuhwirira, kuravira uye kukosha kwekudya. Chero bedzi ichigona kusvika padanho rakati re vacuum, mhedzisiro yacho yakafanana.

Kuwana hakufanirwe kunge kuchidhura, kuchitora nguva, kana kuti kuchinetsa. Zvese zvinoenderana nenzira chaiyo uye nzira yekuyera nayo.

Maitiro ese enguva refu nezviito zvenguva pfupi zveSmart Weigh zvichaumbwa nehurongwa hwezvinhu zvakakosha zvinogovaniswa nemumwe nemumwe wevanobatana navo.

Weigher inotengeswa mumusika we oversees uye ine mukurumbira wepamusoro. Pamusoro pezvo, zvigadzirwa zvedu zvinotengeswa nemitengo inonzwisisika.
