Mphika woyeretsera umatchedwanso mphika woyeretsera. Ntchito ya mphika woyeretsera ndi yayikulu kwambiri, ndipo imagwiritsidwa ntchito makamaka m'magawo osiyanasiyana monga chakudya ndi mankhwala.
Chotsukiracho chimapangidwa ndi thupi la mphika, chivundikiro cha mphika, chipangizo chotsegulira, wedge yotseka, chipangizo chotetezera cholumikizira, njanji, dengu loyeretsera, nozzle ya nthunzi ndi ma nozzle angapo. Chivundikirocho chimatsekedwa ndi mphete yotsekera yolimba ya silicone yomwe imapumira kutentha, yomwe ndi yodalirika komanso yogwira ntchito nthawi yayitali.
Pogwiritsa ntchito nthunzi yokhala ndi mphamvu inayake ngati gwero la kutentha, imakhala ndi mawonekedwe a malo otenthetsera akuluakulu, kutentha kwambiri, kutentha kofanana, kutentha kwa madzi kwa nthawi yochepa, komanso kuwongolera kutentha kosavuta. Thupi la mphika wamkati (mphika wamkati) wa mphika uwu limapangidwa ndi chitsulo chosapanga dzimbiri cha austenitic chosagwira asidi komanso chosagwira kutentha, chokhala ndi choyezera kuthamanga ndi valavu yotetezera, yomwe ndi yokongola, yosavuta kuyiyika, yosavuta kugwiritsa ntchito, yotetezeka komanso yodalirika.
Mafakitale ambiri odyetsera chakudya amagwiritsa ntchito mtundu uwu wa mankhwala oyeretsera opingasa akamatenthetsa ndi kuyeretsa zinthu zomwe zapakidwa m'madzi pansi pa mphamvu yachibadwa. Zipangizozi zimayeretsa mpweya wopanikizika kumbuyo mwa kuyambitsa mpweya wopanikizika. Ngati kuziziritsa kuyenera kuchitika mumphika, pampu yamadzi iyenera kupopedwa mu chitoliro chopopera madzi pamwamba pa mphika (kapena kugwiritsa ntchito njira yoyendetsera madzi). Panthawi yoyeretsa, mphamvu mkati mwa thumba losungiramo zinthu idzapitirira mphamvu yakunja kwa thumba (mumphika) chifukwa cha kutentha komwe kumakwera chifukwa cha kutentha. Chifukwa chake, kuti tipewe kuwonongeka chifukwa cha kupanikizika mu phukusi panthawi yoyeretsa, ndikofunikira kugwiritsa ntchito mphamvu yotsutsana, kutanthauza kuti, mpweya wopanikizika umadutsa mumphika kuti uwonjezere mphamvu kuti upewe kuwonongeka kwa phukusi. Ntchitoyi ikufotokozedwa motere:
Popeza mpweya wopanikizika ndi woyendetsa kutentha wofooka, ndipo nthunzi yokha imakhala ndi mphamvu inayake, panthawi yotenthetsera yoyeretsa, mpweya wopanikizika suyikidwa mumphika, koma pokhapokha ngati wasungidwa wofunda pambuyo poti kutentha kwa sterilization kwafika, mpweya wopanikizika umatulutsidwa mumphika. Mkati, onjezerani mkati mwa mphika ndi 0.15-0.2Mpa. Mukayeretsa, mukaziziziritsa, siyani kupereka mpweya, ndikukanikiza madzi ozizira mu chitoliro chopopera. Pamene kutentha mumphika kukutsika ndipo nthunzi ikuchepa, mphamvu ya mpweya wopanikizika imagwiritsidwa ntchito kubwezera kuchepa kwa mphamvu yamkati ya mphika.
Pa nthawi yoyeretsera, muyenera kuyang'anitsitsa utsi woyamba, kenako kutulutsa mpweya, kuti nthunzi izitha kufalikira. Imathanso kusungunuka kamodzi pa mphindi 10 zilizonse kuti ipititse patsogolo kusinthana kwa kutentha. Mwachidule, mikhalidwe yoyeretsera iyenera kukwaniritsidwa ndikuchitika motsatira njira zina. Kutentha kwa kuyeretsera, kuthamanga kwa kuyeretsera, nthawi yoyeretsera ndi njira yogwirira ntchito zonse zimafotokozedwa ndi njira yoyeretsera ya zinthu zosiyanasiyana.
Pali mitundu yambiri ya zoyeretsera, zomwe zambiri zimapangidwa malinga ndi zosowa za makasitomala, ndipo kukula kwa zida kumapangidwa malinga ndi zomwe makasitomala amafunikira komanso momwe chomeracho chilili. Kupanikizika ndi kutentha kumayendetsedwa ndi PLC yolondola kwambiri, ndipo kuthamanga ndi kutentha zimakhala zokwera kwambiri. Kukonza machenjezo oyambirira.
