Mfundo yosungira makina opaka vacuum

M'zaka zaposachedwapa, anthu amafunikira kwambiri ma phukusi kuposa kale, koteromakina opaka vacuumOpanga ayika ndalama zambiri za anthu ndi zinthu zina mu kafukufuku, chitukuko, ndi kupanga makina opaka vacuum. Tsopano ma CD omwe ali pamsika ndi osiyanasiyana, ndipo ntchito zake zikupangidwa kwambiri. Makina opaka vacuum amaletsa kuwonongeka kwa chakudya pochepetsa kuchuluka kwa mpweya. Popeza kuwonongeka kwa chakudya kumachitika chifukwa cha ntchito ya tizilombo toyambitsa matenda, mpweya ndi wofunikira kuti tizilombo toyambitsa matenda ambiri tipulumuke. Chopaka vacuum ndiye chifukwa cha ndalama zotumizira. Matumba a mpweya amatseka, zomwe zimapangitsa kuti tizilombo toyambitsa matenda tisapulumuke m'chilengedwe. Pamene kuchuluka kwa mpweya m'thumba kuli kochepera 1%, kukula ndi kuberekana kwa tizilombo toyambitsa matenda kumatsika kwambiri. Kukula kunatha pamene kuchuluka kwa mpweya kunali kochepera 05%. Onse ndi makina opaka vacuum, omwe amagwiritsidwa ntchito kwambiri m'munda uno. Mfundo yosungiramo firiji ya makina opaka vacuum Makina opaka vacuum amaletsa kuwonongeka kwa chakudya pochepetsa kuchuluka kwa mpweya.

Pamene kuchuluka kwa okosijeni m'thumba kuli kochepera 1%, kukula ndi kuberekana kwa tizilombo toyambitsa matenda kumachepa kwambiri. Kukula kunatha pamene kuchuluka kwa okosijeni kunali kochepera 05%. Zakudya zina zosalimba zimagwiritsa ntchito chopumira mpweya.makina opaka vacuum, chifukwa thumba lodzaza ndi mpweya limatha kupewa kusweka kwa chakudya. Motero zimakhudza mawonekedwe ndi kugwiritsidwa ntchito. Makina opakira opumira a vacuum amadzazidwa ndi N2. Carbon dioxide, mpweya kapena kusakaniza kwa mpweya wosiyanasiyana Nayitrogeni ndi mpweya wosagwira ntchito ndipo umagwira ntchito yodzaza. Carbon dioxide imasungunuka m'madzi kapena mafuta kuti ipange asidi wochepa wa carbonic acid, womwe ungalepheretse bwino mphamvu za tizilombo toyambitsa matenda. Mpweya umasunga mtundu wa zipatso ndi ndiwo zamasamba. Mpweya wambiri umasunga nyama yofiira yatsopano yofiira.
