Eminyakeni embalwa edlule kuye kwafakwa amasistimu amaningi kakhulu emapulazini amakhowe kusetshenziswa ivacuum cooling njengendlela yokupholisa ngokushesha amakhowe.Ukuba nezinqubo zokupholisa ezifanele kubalulekile ekuphatheni noma yimuphi umkhiqizo omusha kodwa kumakhowe kungaba bucayi kakhulu.Nakuba isidingo sabathengi samakhowe anomsoco namnandi siqhubeka sikhula, isikhunta esidumile sinikeza izinselele ezithile kubalimi ngenxa yesikhathi sabo esifushane seshelufu uma siqhathaniswa neminye imikhiqizo.Uma esevuthiwe, amakhowe asengozini enkulu ekukhuleni kwamagciwane.Angakhipha amanzi emzimbeni futhi wonakalise ngokushesha ngaphandle uma aphole ngokushesha futhi agcinwe ezingeni lokushisa elifanele.Ukupholisa i-vacuum kunikeza lapha ikhambi elingcono kakhulu kubalimi elibavumela ukuthi bapholise amakhowe ngendlela ephumelelayo.
Ukubaluleka kwezinga lokushisa elifanele kanye nokulawula umswakama kudlala indima ebalulekile ngemva kokuvuna amakhowe, ukuqinisekisa ikhwalithi eyanele nokuhlala isikhathi eside eshalofini.
Ukubaluleka kokupholisa kwangaphambili
Ukupholisa kwangaphambi kokupholisa kubhekisela ekususeni ngokushesha ukushisa kwensimu (imvamisa cishe ku-80 – 85%) ngemva nje kokuvunwa kwesitshalo.Ukushisa kwensimu kungachazwa njengomehluko wamazinga okushisa phakathi kwezinga lokushisa lesivuno esivunwayo kanye nezinga lokushisa elifanele lesitoreji salowo mkhiqizo.
Ukupholisa ngaphambi kwesikhathi kuyisinyathelo esibaluleke kakhulu esigabeni sangemva kokuvuna njengoba amakhowe ethola ingcindezi ngemuva kokusika.Lokhu kubangela ukuphefumula (ukujuluka, okuholela ekwehleni kwesisindo nokwakhiwa komswakama esikhumbeni somkhiqizo) nokuphefumula okuphezulu (ukuphefumula = ukushisa okushukela), okuholela ekulahlekelweni kokuphila, kodwa ngesikhathi esifanayo ukwanda izinga lokushisa lomkhiqizo, ikakhulukazi uma upakishwe ngokuqinile.Amakhowe ku-20˚C akhiqiza amandla okushisa angu-600% ngaphezulu uma kuqhathaniswa namakhowe ku-2˚C!Kungakho kubalulekile ukuthi zipholise ngokushesha nangendlela efanele.
Kokubili ukuphefumula nokuphefumula kungancishiswa kakhulu ngokupholisa kwangaphambili.Ngokwesilinganiso kokubili kungancishiswa nge-factory engu-4, 5 noma ngisho nangaphezulu, uma kupholiswe phansi kusukela ekuvuneni (ngokwesilinganiso ku-20 – 30 ⁰C / 68 – 86 ⁰F phansi kuya ngaphansi kuka-5 ⁰C / 41⁰F).Izinga lokushisa eliphelele lokugcina lichazwa izici eziningi, njengomkhiqizo okufanele upholiswe kanye nezinyathelo zokuvuna ngemva kokupholisa kwangaphambili.
