Mfundo yogwira ntchito yazakudya vacuum ya thupi
Kutulutsa kwapamwamba kwambiri ku khungu, ku vacuum State, chakudya chosindikizidwa-chosindikizidwa chokhazikika pa thireyi pakati pa chakudya chowoneka bwino cha thupi ndi chassis. Khumbu lanu limakulunga nyama yozizira ngati khungu lachiwiri, lomwe limatha kusunga mtunduwo, fungo labwino la nyama yozizira kwa nthawi yayitali, ndipo ili ndi njira yovomerezeka. Masanjidwe amthupi amapangidwa makamaka ndi filimu ya pakhungu, vsp mafuta ndi mafilimu. Masanjidwe amthupi amatha kugwiritsidwa ntchito kwambiri mu ng'ombe yatsopano, nsomba zam'madzi zatsopano, nsomba zatsopano zam'madzi, mbalame zatsopano, zonunkhira zatsopano, komanso bakha wowotchera nyama , Nkhuku yanjunda, nyama yophika, miyendo ya nkhuku ndi zinthu zina zophika nyama.
Kanema wapamwamba wa pakhungu ali ndi izi:
A. Paketi yosindikizidwa imatha kusunga mwakachilengedwe, fungo, utoto ndi zolaula za malonda. B. Itha kuletsa mpweyasgen, kulepheretsa kubereka kwa mabakiteriya pamalo ocheperako, khalani atsopano kwa nthawi yayitali ndikuteteza mtundu wa chinthucho. C. Imatha kuletsa makhiristo oundana kuti asapangidwe mu firiri ndikuletsa kuzizira kumawotcha pamtunda. 
Ntchito ndi magwiridwe antchito a vacuum khungu
● Ntchito yapamwamba: Nyama yatsopano, nsomba zam'nyanja zam'nyanja, tchizi zokongoletsedwa, nkhuku zapamwamba, etc. ● Magwiridwe antchito apakale: zotsatira zabwino kwambiri. ● Zida zotsatizana zotetezedwa zimapangidwira ma trays osiyanasiyana. ● Malo obisala otchinga a oxirge ndi madzi otchinga amatha kusankhidwa malinga ndi zomwe zili. ● Masaka onse adzawonetsedwa bwino ndi ma CD, ndipo amathanso kuperekanso moyo wautali kuposa malemba wamba.
Mawonekedwe a vacuum pakhungu
● Kutulutsa bwino: malonda ali ndi mawonekedwe abwino owoneka atanyamula, kulimba mtima, ndipo kumatha kupirira kutentha ndi kutentha kochepa. ● Kuchulukitsa Kwambiri: Kutentha kochepa kwa nthawi yoyambira, kukonza bwino ndikusunga mphamvu. ● Zogulitsa zachilengedwe zanyengo, palibe kuwonongeka kwa chilengedwe ndi ngozi zaumoyo. ● Palibe fungo lovulaza mukanyamula. ● Kutha kwa anti-ukalamba komanso nthawi yayitali yosungirako. ● Ndi filimu yopanga chakudya, mogwirizana ndi malangizo oyenerera a US FDA, ndipo ndi zinthu zobiriwira za rohs.
● Ndi miyeso, bolodiyo ili ndi katundu wopulumutsa, kupulumutsa ndi mtengo. ● Kutsatirana ndi mbaleyo ndi kolimba kwambiri kuonetsetsa kuti patsamba. ● Mafuta abwino kwambiri. ● Zogulitsa za mawonekedwe ndi chilengedwe zitha kukhazikitsidwa.
