Ukususela ngo-1950 ukuya phakathi - 80 - s linqanaba ekuphuhliseni umatshini, ixesha liqala ukusuka kwimpompo elula yokuvelisa.
Phuma emoyeni ngaphakathi kwebhegi, ukuya kulindelekileyo emva kwedigri yevacuum, inkqubo yokutywina epheleleyo.
Isetyenziswa ngokubanzi kwishishini lokutya, ukupakishwa kwevacuum, zonke iintlobo zeemveliso eziphekiweyo, njengenkukhu, ham, iisoseji, i-fillet eyosiweyo, ijerky yenkomo, njl.
Iimveliso ezivundiweyo ezinje ngazo zonke iintlobo zemifuno ecoliweyo kunye neemveliso zesoya, iziqhamo ezomisiweyo, njl. njl
Emva kokupakishwa kwevacuum yokutsha kokutya ixesha elide, yandisa kakhulu ubomi beshelufu yokutya.
Umvelisi wasekhaya we-vacuum
umatshini wokupakisha ingaphantsi kwama-20, iimveliso eziphambili zizixhobo zevacuum eziphakathi.
Ngo-1996, ngenxa yokutsalwa kweshishini lokunyibilikisa i-magnesium, ishishini lomatshini wokupakisha ivacuum ibe luphuhliso olukhawulezayo.
Ngapha koko, umatshini wokupakisha wevacuum yindlela yokuvelisa?
Namhlanje, umhleli uya kuba nawe kwaye ujonge.
okokuqala, kufuneka sijonge ukuba yintoni ivacuum.
Uhlobo lobushushu lokumpompa umoya kwi-vacuum state, ukutywina, ukupholisa umsebenzi ogqityiweyo wexesha elinye, kufakwe ekutyeni, kwiimveliso zasemanzini, kwimathiriyeli ekrwada yeekhemikhali, izinto zombane, iindawo ezichanekileyo kunye nezinye iimveliso zokutywinwa kwevacuum, kunokuthintela i-oxidation, ukungunda, ukubola. , ukufuma, kodwa ukwandise imveliso ngekhwalithi elungileyo ubomi obutsha bokugcinwa komatshini.
I-vacuum ikwisithuba esinikiweyo, urhulumente uphantsi kunoxinzelelo lwe-atmospheric yegesi yesiganeko somzimba.
Kwi & nezinye;
Ingenanto & kuyo yonke;
, ngenxa yokuba akukho nto iphakathi, isandi asikwazi ukusasazeka, kodwa ukuhanjiswa kwe-electromagnetic wave akuchatshazelwa yi-vacuum.
Enyanisweni, kwi-vacuum, inkqubo ye-vacuum ijoliswe kwi-atmosphere, inxalenye yezinto eziphathekayo kwindawo ethile iyagxothwa, uxinzelelo lungaphantsi koxinzelelo oluqhelekileyo lwe-atmospheric, ngoko ngokuqhelekileyo sibiza le ndawo i-vacuum okanye i-vacuum.
Vacuum nge-PASCAL (ngokuqhelekileyo
Pascal)
Okanye thor (
Torr)
Njengeyunithi yoxinzelelo.
Kwimeko-bume yendalo, yindawo yangaphandle kuphela ekufutshane ne-vacuum yendawo.
umatshini wokupakisha we-vacuum usebenzisa umgaqo we-vacuum, kwakhona uthi impompo yokucoca isebenzisa lo mgaqo ukuphumeza ukupakishwa kwe-vacuum yemveliso.
Oku kunokwandisa ubomi beshelufu yokutya, kuthintele ukonakaliswa kokutya.
Okanye uloyiko oluninzi lokuba ngumatshini wokupakisha we-oxidized vacuum unokusetyenziselwa ukupakisha ukupakisha.
I-
multihead weigher ithandwa ngumntu wonke kwaye isetyenziswa kwikhaya ngalinye.
Ungathembela kwi-Smart Weigh
