Nkhani zokhudza chitetezo cha chakudya zimagwirizana ndi thanzi la aliyense, kotero anthu nthawi zonse akhala akuchiyang'ana kwambiri. Makamaka m'zaka zaposachedwa, chifukwa cha kuchuluka kwa zinthu zakuthupi zomwe anthu ali nazo komanso kusintha kwa miyoyo yawo, kufunikira kwa kuyesa chakudya kwapitirirabe kukula.

Ndipotu, ntchito yoyesa chakudya ndi kufufuza momwe chakudya chilili nthawi zambiri imagawidwa m'magulu awiri: limodzi ndi la zinthu zaukhondo, ndipo lina ndi la zinthu zabwino.

Komabe, mosasamala kanthu kuti ndi mtundu wanji, ndikofunikira kuonetsetsa kuti zotsatira za mayeso ndi zolondola, apo ayi sizingatheke kupanga kusanthula kwina ndi kuwonetsa. Kuphatikiza apo, kupatula zitsanzo zomwe ziyenera kuyesedwa, ngati pali vuto ndi madzi, ma reagents, kapena magalasi panthawi yowunikira chakudya mu labotale, ndiye kuti kutsimikizika kwa zotsatira za mayeso azakudya kudzakayikiridwa.

Njira zoyambira zowunikira chitetezo cha chakudya

Kuyesa chitetezo cha chakudya ndi kugwiritsa ntchito mfundo zoyambira ndi njira zaukadaulo kuphatikiza fizikisi, chemistry, biology ndi maphunziro ena kuti ayang'ane, adziwe ndikusanthula zosakaniza zazikulu, momwe zinthu zopangira, zinthu zothandizira, zinthu zomalizidwa pang'ono, zinthu zomalizidwa, ndi zina. Masitepe oyambira akuphatikizapo:

① Sonkhanitsani zitsanzo: tsimikizirani cholinga cha mayeso, pangani kuchuluka kwa mayeso ndi zinthu zinazake zoyeserera.

② Kukonzekera zitsanzo: Ikani zitsanzo m'mabotolo oyera, ndipo lembani mabotolo a zitsanzo molingana ndi manambala otsatizana omwe ali pa zitsanzo. Zizindikiro zomwe zapangidwa ziyenera kuzindikira momwe chitsanzo chikuyendere. Konzani kukonzekera koyambirira kwa chitsanzo kuti mukonze njira yokhotakhota ya chitsanzo ndi njira yodziwira chitsanzo.

③Zitsanzo zoyesera: Pogwiritsa ntchito zida zogwirizana nazo, ma reagents kapena mayankho okhazikika ndi yankho loyesera zidzayesedwa nthawi imodzi. Pambuyo powerengera zotsatira za mayeso ndikupeza zolemba zoyambirira, lipoti loyesa likhoza kulembedwa.

Mu njira imeneyi, madzi, zinthu zoyeretsera, ndi magalasi zimagwira ntchito zosiyanasiyana.

Madzi: Madzi oyera okonzedwa mwapadera ndi madzi osungunuka ndi chinthu chofunikira kwambiri pakuwunika chakudya. Kawirikawiri, zinthu zoyesera, monga kukonzekera reagent ndi gawo la njira yoyesera, gwiritsani ntchito madzi wamba osungunuka ngati chisankho chachikulu. Ndikofunikira kudziwa kuti pamene kufufuza zinthu zina kukuchitika, kuzindikira kwa madzi osungunuka kuyenera kukonzedwanso asanayambe gawo lotsatira la kuyesa chakudya.

Ma Reagents: Ma reagents omwe ali mu mayesowa ayenera kugwiritsidwa ntchito moyenera kuti akhudze mwachindunji sayansi ndi kulondola kwa zotsatira za kuwunika chakudya. Chisamaliro chapadera chiyenera kuperekedwa pa nthawi yosungiramo mankhwala. Kuchuluka ndi mtundu wake ziyenera kuyesedwa nthawi zonse, ndipo kugwiritsa ntchito mankhwala omwe atha ntchito n'koletsedwa, apo ayi zidzakhudza kulondola kwa zotsatira zodziwira. Kuphatikiza apo, kuyika tit yankho motsatira malangizo oyenera kungachepetse chiopsezo cha kulephera kwa ma reagents.

Zipangizo zagalasi: Pakadali pano, mabotolo agalasi kapena zinthu zopangidwa ndi polyethylene zimagwiritsidwa ntchito makamaka m'zidebe zoyesera chakudya, zomwe zingagwiritsidwe ntchito kusungiramo mankhwala, kunyamula mankhwala, ndi mankhwala oyesera. Monga machubu oyesera, ma beakers, ma flasks a volumetric, ma flasks oyezera ndi ma flasks a Erlenmeyer. Koma chofunika kwambiri ndikuwonetsetsa kuti ukhondo ndi kusatulutsa madzi kwa zidebe zagalasi izi zikutsatira miyezo ndi zofunikira. Chifukwa chake, chidebe cha chinthu choyesera chiyenera kutsukidwa bwino ndi kutsukidwa musanagwiritse ntchito kuti zitsimikizire kuti palibe zodetsa zomwe zatsala. Ntchito ya magalasi imakhala pafupifupi mbali zonse zofunika kwambiri pakuwunika chakudya.

Kodi ndi zinthu ziti zomwe zimatsalira zomwe zimachitika nthawi zambiri poyesa chakudya? Kodi chingayeretsedwe?

Ntchito iliyonse yoyesera chakudya idzapanga zinthu zotsalira mu ziwiya zagalasi, monga zomera za tizilombo toyambitsa matenda, zotsalira za mankhwala ophera tizilombo, formaldehyde, zitsulo zolemera, ma protease, zowonjezera chakudya, zolimbitsa thanzi, zotsalira za reagent mu kuyesa, choyambitsa kutsuka panthawi yoyeretsa, ndi zina zotero. Chifukwa chake, ziwiya zagalasi ziyenera kutsukidwa musanagwiritse ntchito. Koma njirayi sikuti imangokhala yoyeretsa pamanja. Popeza kuchuluka kwake, kusiyanasiyana, kusowa kwa anthu ogwira ntchito, komanso nthawi yochepa, tiyeni tiwone zabwino zake.makina ochapira a labuyopangidwa ndi Hangzhou Xipingzhe Instruments Technology Co., Ltd? Mwachitsanzo, zotsatira zoyeretsa sizodalirika komanso zolondola kuposa kuyeretsa pamanja, komanso zimatha kujambulidwa, kutsimikizika, komanso kubwerezedwa! Kuphatikiza ndi anzeruchotsukira magalasi chokhaKuti muwongolere njira yoyeretsera, zimathandiza kwambiri kuti kuyesa konse koyesa chakudya kukhale bwino komanso kuti chitetezo chikhale chotetezeka.

Mwachidule, kuti kukhale kolondola kwa zotsatira zoyesa chakudya ndi komwe makampani oyesa chakudya akupitiliza kukwaniritsa. Kuti zotsatira zowunikira chitetezo cha chakudya zigwirizane ndi deta yeniyeni yoyesera, madzi, ma reagents, ndi magalasi ndizofunikira kwambiri. Makamaka, kuyeretsa kwachotsukira ziwiya zagalasiZingathe kupititsa patsogolo ukhondo nthawi zonse kuti zikwaniritse miyezo yoyezera chakudya yomwe ikuyembekezeredwa. Mwanjira imeneyi yokha ndi momwe zingagwiritsidwe ntchito moyenera ngati maziko enieni komanso olondola. Ndikukhulupirira kuti oyang'anira chakudya adzakumbukira izi, ndipo asalole kuti ntchito yowunikira chitetezo cha chakudya ilephereke kapena kuwonongeka chifukwa choyeretsa magalasi.
