Munguva yehupenyu hwakakurumidza-hwakakurumidza, chikafu-chikafu chiri kuwana yakawanda uye zvakanyanya fashoni munguva pfupi yapfuura, kunyanya pakati pevadiki. Vazhinji vanhu vazhinji havana nguva yakakwana kana chishuvo chekugadzirira ndiro. Ivo vanofarira kutora imwe chikafu yakagadzirirwa, pop navo mu microwave, uye ding, zvese zvakaitwa. Kudya kwakagadzirirwa kusingachengetedze nguva yedu mukugadzirira chikafu asi zvinotibatsirawo kuti tisvike pachinangwa chekusimba.
Zvepamberi2020 zvakapupurirawo mukurumbira wezvakagadzirira-kudya. Hapana mabara, hapana kuunganidza, hapana mudumbu wemukati, denda rasiya akawanda maresitorendi ari panjodzi yekuvhara pasi. Zvakadaro, mamwe masevhisi ezvekudya akanakidzwa nebhizimusi rinoita kuburikidza nekutora chikafu. Uyezve, nhamba inowedzera yenhetemake inopa vakasiyana-siyana chikafu pamasherufu.
Saizvozvo akatarisana nezvikafu zvakawandisa, zvatichanhonga?
Kunze kwekuravira uye kuravira, ini ndinofunga kuti pakeji yacho inofanira kuve yakakosha.
Zvakakosha zvinowanikwa zvinogona kugadzira chikafu chekudya, asi iyo phukusi hairevi nhema. Kunyangwe kudikanwa kwekukurumidza kumhanya uye nyore, vatengi vanogara vachida kudya chikafu chine hutano uye chitsva. Saka maitiro ekuita izvo zviyero, ibasa remakesi akakodzera.
Parizvino, iyo inomuka-freshiges yekugadzira chikafu imepu uye vs.
Chii chinonzi mepu?
Mepu ipfupi kune yakawanda mamiriro ekupfeka. Mushure mekubvisa mweya muchero nyaya, isu tichaisa mamwe magasi anodzivirira senge co2 uye No2 kuchengetedza kugara kwenguva refu uye kutsiva.
Chikafu chinoshanduka ichikurumidza kukurumidza kuratidzwa kwemhepo sezvo microorms akawanda anokura nekukurumidza munzvimbo ine okisiGen. Nekudaro, kudzora okisijeni mwero ndiyo yekutanga zvakare inhanho yakakosha pamepu. Carbon Dioxide inoshanda kwazvo mukunyanyisa Aerobic Spoilage Microorganisms uye kuderedza iyo yekufema yekufema yechikafu chitsva. Nepo nitrogen inowanzoshandiswa kudzivirira kudonha kwepakeji. Iko kusarudzwa kwekupedzisira kwegasi musanganiswa kunoenderana nezvivakwa zvezvikafu
Chii chinonzi vs?
Vs, abrr. yevacuum ganda ratidziro. VSP inoshanda kupisa uye vacuum yekuvhara chigadzirwa neyakagadzirirwa kuputira firimu, yakakodzera seganda rechipiri. Inobvisa mweya yese yakatenderedza chikafu asi kukiya mumanyoro matsva ipapo. Semhedziso yakanaka kwazvo yekuisa, yakave yakanyatsoshandiswa mune zvekudya zvakasiyana-siyana zvakatsanangurwa uye zvakagadziriswa. Izvo hazvingobatsire kungopa pasherufu nguva asi zvakare inosimudzira mharidzo yayo 'zvizere zvizere.
Utien ine ruzivo rwakapfuma mune zvekudya zvekudya zvekudya. Kana iwe ukambove nekubvunza kwakadaro, takagadzirira kukushandira.
