Nthawi zonse fotokozani ubwino wogwiritsira ntchito chakudya, kotero pali anthu ambiri amakayikira vacuum
makina onyamula ikhoza kuikidwa nthawi yayitali bwanji mutatha kuyika vacuum, kaya ikugwirizana ndi chitetezo cha chakudya ndi zina zambiri zovuta.
Makina onyamula a vacuum amatha kutulutsa mpweya mkati mwa thumba, ndikukwaniritsa kusindikiza kwa vacuum.
Tekinoloje yonyamula vacuum idayamba m'ma 1940.
Mu 1950, polyester, polyethylene pulasitiki filimu bwinobwino ntchito vakuyumu ma CD, kuyambira pamenepo, vakuyumu ma CD ndi kupeza chitukuko mofulumira.
Vacuum wazolongedza makina nthawi zambiri ntchito makampani chakudya, chifukwa pambuyo zingalowe ma CD, chakudya antioxidant, kukwaniritsa cholinga cha kusunga nthawi yaitali.
Vuto ndiloti liyenera kupititsa mayeso kuti lipeze zotsatira zolondola.
Monga taonera alumali moyo pa ma CD chakudya, kokha pamene ogwira ntchito mwaukadaulo dipatimenti pambuyo mayeso, akhoza kudziwa.
komanso pa webusayiti lero kusonkhanitsa mafunso ambiri okhudza vacuum atanyamula chakudya alumali moyo.
Makina odzaza otopa okha ndi oyenera kudula nyama yowuma, nyama yozizira yatsopano, zinthu za soya monga nyama, nsomba zam'nyanja, zokhwasula-khwasula chakudya, mankhwala, zida zamankhwala, zida zamagetsi, zida zamagulu amagetsi, zinthu zamakampani monga vacuum kapena kuyika gasi, zotengerazo zakhala. chizolowezi cholongedza chakudya m'tsogolomu.
Tiyeni tione ayenera kudziwa ulemu.
Mitundu ya alumali moyo wa chakudya ndi zakudya zokhudzana ndi vacuum pretreatment musananyamuke.
Zakudya zamitundu yosiyanasiyana, kapena njira yopangira mankhwala, kulongedza kwa vacuum kumakhala kosiyana pambuyo pa nthawi yosungira kutentha.

Zochokera zinachitikira Mwachitsanzo, ngati kusunga chakudya firiji kwa masiku awiri, ayenera mwatsopano ulimi mankhwala kapena kukonzedwa pang'ono kukonzedwa nyama.
Ngati ndi choncho, mutatha kulongedza vacuum, imatha kukulitsidwa mpaka masiku asanu ndi limodzi.
Zina zitha kuonjezedwa mpaka masiku 18.
Nthawi yotsalira nthawi ya deli ndi yaifupi, zipatso zouma, ngakhale miyezi 12.
Adzayesa chinthu china chake.
zotsatirazi makamaka za mfundo ya kusunga vakuyumu wazolongedza, kuti amvetse vuto la alumali moyo: zingalowe kulongedza katundu ntchito mpweya ndi ntchito yaikulu ya zingalowe ma CD makina, pofuna kupewa kuwonongeka chakudya, mfundo ndi yosavuta.
Chifukwa kuwonongeka kwa mildew kumayamba chifukwa cha zochita za tizilombo tating'onoting'ono, komanso tizilombo toyambitsa matenda (microorganisms)
Monga nkhungu ndi yisiti)
Zofunikira kuti pakhale moyo wa okosijeni, komanso kunyamula vacuum ndiko kugwiritsa ntchito mfundo imeneyi.
Thumba chakudya ndi mpweya m'maselo wachotsedwa, tizilombo anataya & zina
chilengedwe & lonse;
.
Zotsatira zimasonyeza kuti pamene mpweya ndende mu thumba kukhala zosakwana 1%, kukula kwa tizilombo toyambitsa matenda kubereka mlingo anagwa kwambiri, ndende mpweya & le;
Ku zero.
5%, tizilombo toyambitsa matenda ambiri amaletsa, kusiya kuswana.
Zindikirani: kulongedza vacuum kungathe kulepheretsa kuswana kwa mabakiteriya a anaerobic komanso ma enzyme omwe amayamba chifukwa cha kuwonongeka kwa chakudya, kuzizira, kuzizira, kutaya madzi m'thupi, kutsekemera kwa kutentha kwambiri, kutseketsa kwa radiation, kutsekereza kwa microwave, mchere ndi njira zina zothandizira.
Vacuum deaerating osati ziletsa kukula kwa tizilombo kuswana, ntchito ina yofunika ndi kuteteza makutidwe ndi okosijeni wa chakudya, chifukwa mafuta chakudya lili zambiri unsaturated mafuta zidulo, makutidwe ndi okosijeni ndi mpweya, kupanga chakudya kununkhira metamorphism.
Komanso, makutidwe ndi okosijeni kumapangitsanso vitamini A ndi vitamini C kutaya, chakudya pigment wosakhazikika zinthu mchikakamizo cha mpweya, kupanga mtundu mdima.
Oxygen imatha kuteteza kuwonongeka kwa chakudya, choncho, sungani mtundu wake, fungo lake, kukoma kwake ndi zakudya.
Malingana ngati ingathe kufika pa digiri ya vacuum, zotsatira zake zimakhala zofanana.
Kupeza sikuyenera kukhala kodula, kuwononga nthawi, kapena kovuta. Zonse zimabwera ku njira yoyenera komanso choyezera choyezera m'malo mwake.
Njira zonse zanthawi yayitali komanso zochita zazifupi za Smart Weigh zidzawumbidwa ndi zikhalidwe zazikulu zomwe zimagawidwa ndi mnzake aliyense.
weigher amagulitsidwa pamsika woyang'anira ndipo ali ndi mbiri yabwino. Kupatula apo, zinthu zathu zimagulitsidwa pamitengo yabwino.
