Ukuhamba komsebenzi:
I-1, i-vacuum: igumbi lokucoca igumbi elivaliweyo, umsebenzi wempompo yokucoca, igumbi lokucoca laqala ukupompa i-vacuum, i-vacuum engxoweni ngaxeshanye, isalathisi se-vacuum gauge siyenyuka, sifikelele kwi-vacuum elinganisiweyo (elawulwa yi-vacuum ye-relay ISJ) Yeka ukusebenza, vacuum stop. Ngexesha elifanayo lomsebenzi we-vacuum, i-valve ye-IDT ye-solenoid eneendlela ezimbini, i-vacuum yokutywina ubushushu, i-vacuum yokushisa ubushushu igcinwe kwindawo.
2, ukutywinwa kobushushu: Ikhefu le-IDT, umoya wangaphandle ngokungena komoya ongaphezulu kwigumbi lokutywina lobushushu, ukusetyenziswa kwegumbi lokucoca elinomohluko woxinzelelo phakathi kwegumbi legesi yokutywina ubushushu, ukutywinwa kwegesi kwigumbi lokwandiswa kwegesi, ukuze isakhelo soxinzelelo lobushushu phantsi, cinezela umlomo wengxowa; ngelo xesha, umsebenzi wokuguqula ukutywinwa kobushushu, qalisa ukutywinwa; ngexesha elifanayo, ixesha lokubuyisela i-2SJ umsebenzi, imizuzwana embalwa emva kwesenzo, ukuphela kokutywinwa kobushushu.
I-3, ubuyela emoyeni: i-valve ye-solenoid ye-2DT eneendlela ezimbini, i-atmosphere kwi-vacuum ye-vacuum, i-vacuum gauge pointer ibuyele kwi-zero, isakhelo sokushicilela eshushu sixhomekeke ekusetweni ngokutsha kwentwasahlobo, igumbi lokucoca elivulekileyo.
Indlela yokwenza:
Umsebenzi oyintloko wokupakishwa kwe-vacuum yi-deoxygenation, ukukhusela ukonakala kokutya, umgaqo ulula, kukususa i-oksijini kunye neeseli zokutya engxoweni, ukuze ii-microorganisms zilahlekelwe yindawo yazo yokuhlala. Iimvavanyo zibonisa ukuba: xa i-oksijeni yoxinaniso kwisikhwama ingaphantsi kwe-1%, ukukhula kunye nokuzala kwe-microorganisms kuya kuhla ngokukhawuleza, xa i-oxygen concentration ingaphantsi kwe-0.5%, i-microorganisms ezininzi ziya kuvinjelwa kwaye ziyeke ukuvelisa. (Qaphela: ukupakishwa kwe-vacuum akukwazi ukuthintela ukuveliswa kwebhaktheriya ye-anaerobic kunye ne-enzyme reaction ebangelwa ukonakala kokutya kunye nokuguqulwa kombala, ngoko kufuneka kudityaniswe nezinye iindlela ezincedisayo, ezifana nefriji, ukukhenkceza ngokukhawuleza, ukuphelelwa ngamanzi emzimbeni, ukutshabalalisa ubushushu obuphezulu, i-radiation. ukuvala inzala, ukwenza inzala kwi-microwave, ukuchola ityuwa, njl.
