Kune zvakawanda zvekudya pamusika parizvino ndeye kushandisa iyozvirongo zvekudya zvepurasitiki, zvichienzaniswa neyechinyakare inochinjika yekurongedza mabhegi, zvirongo zvepurasitiki zvechikafu mukutaridzika zvakanyanya kunaka uye zviri nyore, uye chigadzirwa chinotaridzika zvakanyanya-giredhi, panguva imwe chete mukutakura uye kutengesa maitiro uye kurongedza kuchengetedzwa kwechikafu kune zvakanakira kupfuura zvakapfava zvakajairika. bhegi kurongedza, epurasitiki kurongedza kwechikafu, kazhinji kazhinji, saka, Zvimwe zvakajairika ndedzimwe nzungu, makeke, masiwiti uye zvichingodaro.
Izvi zvekudya zvemumagaba kazhinji zvine matambudziko eoxidation mukuchengetedza, senge nut chikafu oxidation inoratidzwa nekunhuhwirira kwakashata, chikafu chepastry pamwe nekunhuhwirira kwakashata, chinogonawo kuoneka mildew phenomenon.Kugadzirisa matambudziko aya, vagadziri vezvekudya vanowanzo shandisa zvimwe zvinodzivirira, antioxidants, nzira dzekuchengetedza, senge deoxidizer, zvakare kuderedza hunyoro hwechikafu panguva imwe chete, munzira yekuchengetedza, zvakananga kuwedzera antistaling agent kuchengetedza kazhinji zvakare kubvunzwa nevatengi, vachishandisa. deoxidizer kuchengetedza ndiyo nzira yakachengeteka yekuchengetedza, uye mhedzisiro yacho iri pachena.
Paunenge uchishandisa deoxidizers kuchengetedza chikafu chitsva mumagaba epurasitiki, vagadziri vanowanzowana dambudziko rakadaro: sei mapurasitiki echikafu akaremara?
Mumagaba akavharwa epurasitiki shandisa zvakajairika deoxidizer, deoxidizer tora epurasitiki tangi oxygen gettering, oxygen tank air volume inosvika 21%, kana tangi mushure mekunge okisijeni yave deoxidizer kuwana, kudzvanywa kwemhepo mukati metangi kunoderedzwa, kana simba repurasitiki. poto inokwana kuramba kumanikidzwa kwemhepo yekunze, mapurasitiki emagaba contraction deformation phenomenon ichaitika.
Mukugadzirisa dambudziko repurasitiki tangi deformation, vamwe vagadziri vachashandisa dzimwe nzira dzisiridzo, dzakadai sekuda kuvhara gomba pabhaisikopo retangi, kana kushandisa modhi diki kana kutotadza kutora oxygen deoxidizer, kunyangwe nzira iyi inogadzirisa dambudziko epurasitiki tangi deformation, asi kuchengetedza chikafu hakuna mhedzisiro.Chisimbiso tangi pagomba, mhepo iri kunze kwetangi inogona kukurumidza kupinda mutangi, deoxidizer ichakurumidza kukundikana, iyo oxygen concentration mutangi haina kudonha, dambudziko re oxidation richiri kugadzirwa;Kushandiswa kwemhando diki ye deoxidizer, iyo oxygen yekuisa mutangi repurasitiki haina kudonha yakawanda sei, mhepo yekumanikidza mutangi haina kuderedza kuwanda, saka tangi yepurasitiki haina kuremara, asi kune yakawanda yeokisijeni tank, zvirokwazvo haikwanise kugadzirisa dambudziko rekuchengetedza chikafu.
Isu tinowanzo kuve nekusanzwisisa kwakadai, funga chirongo chepurasitiki che deformation nekuda kwe deoxidizer okisijeni simba rakakura kwazvo, kutaura zvazviri, mune yepurasitiki inogona kuita deoxidization, apa hapana pesvedzero pahukuru hwe deformation uye deoxidizer yekusarudza, nekuti, mu tangi yepurasitiki yakavharwa, huwandu hweokisijeni hunogadziriswa, hunoita 21% yetangi yemhepo yemhepo, Kureva kuti, huwandu hweokisijeni mutangi ndeyechokwadi, ingave iri modhi yakawedzerwa, kana diki modhi ye deoxidizer. , iyo yakanyanya shrinkage rate yetangi yakafanana.
Kwete chete mukutakura kwechikafu kunogona kuisa deoxidizer nyowani, asi zvakare kugadzirisa dambudziko rekurongedza kunogona deformation, kune nzira mbiri, imwe ndeyekuwedzera ukobvu uye simba rekurongedza inogona, kuitira kuramba tangi yemhepo kudzvanywa kwakaderedzwa kudzvanywa. , nzira iyi ichaita zvisingadzivisiki kuwedzera mari yekuputira inogona, panguva imwechete, simba rekuvhara firimu harigoni kuvimbiswa zvizere;Chechipiri, uchishandisa nguva dzose kumanikidza rudzi deoxidizer, rudzi urwu rwechigadzirwa cheokisijeni mumhepo panguva imwe chete inogonawo kuburitsa yakaenzana yeokisijeni vhoriyamu yecarbon dioxide, nepo mutengo wechigadzirwa unodhura kupfuura wakajairika deoxidizer, asi unoenderana ne yakawedzera mutengo wekukora emarata epurasitiki akadzikira zvakanyanya, panguva imwecheteyo, nzira iyi inogona kunyatso wedzera chigadzirwa mutengo nguva, inovimbisa kunaka kwechikafu, inogona kuunza mabhenefiti anobatika kune vanogadzira.
